NASA Mission Successfully Knocks Asteroid Moon Off Orbit
Summary
NASA’s DART mission intentionally crashed into Dimorphos, the moon of an asteroid, to test planetary defense techniques.
The collision altered Dimorphos’ shape from a hamburger-like structure to a more football-like shape.
Dimorphos’ orbit was significantly changed, causing it to tumble unpredictably through space.
This mission provides vital data for future planetary defense strategies in case of an asteroid threat to Earth.
The findings challenge previous assumptions about the behavior and formation of asteroid moons.
The DART Mission: A Milestone in Planetary Defense
In 2022, NASA embarked on a groundbreaking mission that aimed to test a method of planetary defense. The Double Asteroid Redirection Test (DART) was designed to determine if a spacecraft could successfully change the trajectory of a celestial object, specifically an asteroid’s moon. The target was Dimorphos, a small moon orbiting the larger asteroid Didymos. The mission’s success not only proved that an asteroid’s orbit could be altered, but it also brought about unexpected changes in Dimorphos’ shape and behavior.
The Purpose of the DART Mission
The primary objective of the DART mission was to explore the potential of using kinetic impact to alter the course of an asteroid. This technique could be crucial in the event of a future asteroid threat to Earth. NASA selected Dimorphos as the target due to its proximity and the fact that it posed no threat to our planet. The mission was part of a broader effort by NASA to develop strategies for planetary defense, ensuring that we have the tools necessary to protect Earth from potential celestial hazards.
When the DART spacecraft collided with Dimorphos, it was expected that the moon’s orbit would be slightly altered. However, the outcome far exceeded expectations. The impact not only knocked Dimorphos out of its natural orbit, but it also physically altered the moon’s shape. Before the collision, Dimorphos was described as being shaped like a hamburger. After the impact, it became more football-like in structure. This transformation was a surprise to scientists, who had previously believed that asteroid moons would naturally elongate over time, with their main axis always pointing toward the asteroid they orbit.
One of the most intriguing findings from the DART mission was that Dimorphos began to tumble unpredictably through space after being knocked off its orbit. Instead of maintaining a stable orientation, the asteroid moon started rotating erratically, with no consistent face pointing toward Didymos. This behavior was unexpected and has led scientists to reconsider their understanding of the gravitational forces and dynamics at play in such systems.
Dr. Derek Richardson, one of the researchers involved in the mission, noted, “This result contradicts the idea that asteroid moons naturally elongate and maintain a stable orientation. Instead, something more complex is at work here, and the impact-induced change in Dimorphos’ shape likely altered its interaction with Didymos.”
The DART mission’s findings have significant implications for future planetary defense efforts. The data gathered from the mission provides valuable insights into how kinetic impact can be used to alter the course of potentially hazardous asteroids. The ability to change an asteroid’s orbit and even its physical structure is a powerful tool in Earth’s defense against external threats. However, the unpredictable behavior of Dimorphos after the impact also highlights the complexity of such missions and the need for further research.

Before the DART mission, it was widely believed that asteroid moons would naturally increase over time, with their main axis always pointing toward the asteroid they orbit. This theory was based on the idea that gravitational forces would gradually shape these moons into elongated forms, similar to how the moon is tidally locked with Earth, always showing the same face. However, the changes observed in Dimorphos have challenged this assumption.
NASA’s DART mission has sent pictures back to Earth. These pictures show the Dimorphos asteroid. DART hit the asteroid as part of a test. This test is the first-ever trial of planetary defense.
The impact from the DART spacecraft caused Dimorphos to contract and become more squished, taking on a football-like shape. This result suggests that asteroid moons may not always follow the predicted pattern of elongation and stable orientation. Instead, the dynamics of these small celestial bodies may be more complex than previously thought.
The DART mission has provided scientists with a unique opportunity to study the effects of a kinetic impact on a small celestial body. The insights gained from this mission are invaluable for understanding the behavior of asteroid moons and the forces that shape them. The unexpected results have opened new avenues for research, prompting scientists to reevaluate existing theories and consider new possibilities.
NASA’s DART mission is just the beginning of a new era in planetary defense. The success of this mission has demonstrated that we have the capability to alter the course of an asteroid and potentially prevent a catastrophic impact on Earth. However, the unpredictable behavior of Dimorphos after the impact underscores the need for further research.
Future missions may focus on studying other asteroid systems to gain a deeper understanding of the dynamics at play. Additionally, scientists are likely to explore new methods of planetary defense, building on the knowledge gained from the DART mission. These efforts will be crucial in developing a comprehensive strategy to protect Earth from potential asteroid threats.
Conclusion
NASA’s DART mission has marked a significant milestone in the field of planetary defense. The mission not only demonstrated the ability to alter the course of an asteroid moon but also provided valuable insights into the complex dynamics of celestial objects. The unexpected changes observed in Dimorphos have challenged existing theories and opened new avenues for research. As we look to the future, it is clear that planetary defense will continue to be a critical area of focus. By building on the success of the DART mission and continuing to invest in research and technology, we can ensure that we are prepared to protect our planet from potential threats.
NASA Plans February Return for Starliner Astronauts on Different Craft
Summary
NASA announces that astronauts Barry “Butch” Wilmore and Sunita “Suni” Williams will return to Earth in February 2025 aboard SpaceX’s Crew Dragon 9, instead of the Boeing Starliner.
The Boeing Starliner will return uncrewed due to safety concerns, especially with the vehicle’s thrusters.
The return of the astronauts has been delayed multiple times, and they are currently assisting with science experiments and maintenance on the International Space Station (ISS).

NASA Plans February Return for Starliner Astronauts on Different Craft
The two astronauts who embarked on a mission to the International Space Station (ISS) aboard Boeing’s Starliner will not be returning on the same spacecraft. NASA has announced that astronauts Barry “Butch” Wilmore and Sunita “Suni” Williams will return to Earth in February 2025 on SpaceX’s Crew Dragon 9. The Boeing Starliner, meanwhile, will return to Earth uncrewed, marking a significant shift in NASA’s plans due to ongoing safety concerns.
The mission began on June 5, 2024, when Wilmore and Williams launched aboard the Boeing Starliner. This mission was meant to be the first crewed test flight of Starliner under NASA’s Commercial Crew Program. Initially, the plan was for the astronauts to stay on the ISS for about a week and return by June 14, 2024. However, this timeline has been repeatedly extended due to various issues encountered by the Starliner spacecraft.
“Safety is our top priority, and the decision to bring Butch and Suni home on a different spacecraft underscores our commitment to that,” said Bill Nelson, NASA Administrator, during a recent news conference. The unexpected need to extend the astronauts’ stay on the ISS has had far-reaching implications, including additional strain on the resources aboard the station.
Boeing’s Starliner spacecraft has faced a series of challenges both before and after its launch. The mission was originally scheduled for May 6, 2024, but was delayed due to a problem with an oxygen valve on a rocket from United Launch Alliance (ULA), the company responsible for launching the spacecraft into orbit. A new launch date of May 25, 2024 was set, only to be postponed again due to a small helium leak discovered in the service module.
Once in orbit, further problems emerged. The Starliner’s thrusters showed signs of malfunction, raising concerns about the spacecraft’s ability to safely return to Earth with the astronauts onboard. Despite the initial plan to address these issues while docked at the ISS, NASA has determined that the risks are too high for a crewed return.
NASA has been exploring various options to ensure the safe return of Wilmore and Williams. One such plan involves modifying the upcoming SpaceX Crew Dragon 9 mission. Originally scheduled to launch to the ISS in September 2024 with four astronauts, NASA is considering sending the spacecraft with only two crew members to make space for additional supplies, including extra spacesuits for Wilmore and Williams.
If this plan is approved, Wilmore and Williams would remain on the ISS until February 2025, when they would finally return to Earth aboard the Crew Dragon 9. Stich emphasized that this plan is still under review, and no final decision has been made. The modifications would involve updating the Starliner software and additional training for the Boeing flight control team to ensure a safe uncrewed return of the spacecraft.
The Boeing Starliner is part of NASA’s larger Commercial Crew Program, which aims to develop reliable and cost-effective crew transportation to the ISS. The program has seen significant progress with SpaceX’s Crew Dragon, which has successfully completed multiple missions to and from the ISS. However, Boeing’s Starliner has been plagued by delays and technical issues.
The issues with the Starliner spacecraft have raised concerns about Boeing’s ability to meet NASA’s stringent safety standards. A spokesperson for Boeing reiterated the company’s commitment to safety, stating, “Boeing continues to focus, first and foremost, on the safety of the crew and spacecraft. We are executing the mission as determined by NASA, and we are preparing the spacecraft for a safe and successful uncrewed return.”
While Wilmore and Williams were initially scheduled for a short stay on the ISS, their mission has now extended into a much longer period. During this time, they have integrated with the Expedition 71 crew, assisting with a range of research activities and maintenance tasks. NASA officials have indicated that the extended stay has put additional strain on the ISS’s resources, as the astronauts have been using supplies originally allocated for the station’s permanent crew.
Despite the challenges, Wilmore and Williams have continued to contribute to the mission. “We are doing everything we can to support the science experiments and the maintenance of the ISS,” said Williams in a recent interview from space. The astronauts have also participated in a series of spacewalks, further showcasing their adaptability and resilience in the face of an extended mission.

How NASA Monitors Asteroids
NASA uses a combination of ground-based telescopes and space-based observatories to track asteroids. The NEOWISE mission, for example, is dedicated to identifying and characterizing near-Earth objects. The Arecibo Observatory and Goldstone Solar System Radar also play crucial roles in determining the size, shape, and speed of asteroids.
NASA’s Techniques for Tracking Asteroids
Optical Telescopes: Capture images of asteroids and determine their orbits.
Radar Observations: Provide detailed data on the size, shape, and rotation of asteroids.
Infrared Observations: Measure the heat emitted by asteroids to determine their composition.
Spectroscopy: Analyzes the light reflected from asteroids to identify their mineral content.
The Jet Propulsion Laboratory’s Center for Near Earth Object Studies (CNEOS) constantly updates the orbits of known asteroids and calculates their likelihood of Earth impact. Although the probability of an impact is low, vigilance is essential to ensure that any potential threat is identified well in advance.
Can Asteroids Destroy Earth?
Asteroids have been a part of Earth’s history since its formation. While small asteroids frequently enter Earth’s atmosphere, they mostly burn up before reaching the surface. Larger impacts, however, have had catastrophic effects in the past.
The Chicxulub impact around 66 million years ago is the most famous example of a catastrophic asteroid collision. This event is widely believed to have caused the mass extinction that wiped out the dinosaurs. The asteroid, estimated to be about 6 miles in diameter, released energy equivalent to billions of atomic bombs.
Although such impacts are rare, the potential consequences are significant. For an asteroid to cause global destruction today, it would need to be at least 6 miles wide. Smaller asteroids, while destructive on a regional scale, do not pose a global threat.
According to the Planetary Science Institute, the likelihood of a catastrophic asteroid impact is extremely low. Most asteroids larger than 500 feet in diameter have been discovered and their orbits mapped. The remaining undiscovered asteroids are likely to be much smaller and less dangerous.
NASA is constantly improving its detection capabilities to identify even smaller asteroids. However, the vast majority of near-Earth objects pose no threat due to their size or the trajectory of their orbits.
Preparing for Potential Threats
While none of the five asteroids passing Earth next week pose any danger, NASA remains prepared for future threats. Strategies for reducing an asteroid impact include deflection techniques, such as kinetic impactors and gravity tractors. These methods aim to alter an asteroid’s trajectory well before it can reach Earth.
The Double Asteroid Redirection Test (DART) mission, launched by NASA in 2021, demonstrated the feasibility of deflecting an asteroid. The spacecraft successfully altered the orbit ofDimorphos, a moonlet of the asteroid Didymos, marking a significant milestone in planetary defense.
The upcoming flybys of these five asteroids are a reminder of the dynamic environment in which our planet exists. While they pose no danger, their presence underscores the importance of continued vigilance and research. As we learn more about these celestial visitors, we gain insights into the history of our solar system and prepare for the challenges that lie ahead.
A New Era in Lunar Communication: Axiom Space and Nokia’s Groundbreaking Partnership
The race to establish a sustainable human presence on the moon has led to some of the most innovative partnerships in space exploration history. Among these, the collaboration between Axiom Space and Nokia stands out as a significant leap forward. Announced on August 21, 2024, this partnership aims to integrate cutting-edge 4G/LTE wireless communication technologies into the spacesuits that Axiom Space is developing for NASA’s Artemis program.
At the heart of the Axiom-Nokia collaboration is the Lunar Surface Communications System (LSCS), a sophisticated communication network designed to support the Artemis spacesuits. The LSCS system will consist of two main components:
Network in a Box: This includes a base station, antennas, and other supporting systems installed on the Human Landing Services lander.
User Module: Integrated within Axiom’s spacesuits, this module will enable astronauts to connect to the LSCS seamlessly.
The system aims to provide redundancy for existing communication channels, such as UHF and Wi-Fi, while significantly increasing bandwidth. This enhancement allows for high-definition video streaming, real-time data transmission, and improved communication between astronauts and mission control.
The Artemis program, a critical part of NASA’s long-term lunar exploration goals, seeks to return humans to the moon by 2026. Axiom Space’s involvement in developing the next-generation extravehicular activity (EVA) suits is crucial to this mission. The addition of Nokia’s 4G/LTE technology will elevate the capabilities of these suits, allowing astronauts to perform more complex tasks with higher efficiency.
Russell Ralston, Axiom Space’s executive vice president of extravehicular activity, highlighted the importance of this technology in a recent interview. “From a suit perspective, we like this because it will give us a lot more capability and it gives us a little bit more redundancy in the communications,” he said. The LSCS technology offers a unique blend of reliability and versatility, providing astronauts with multiple communication options based on mission requirements.
One of the most significant benefits of the LSCS technology is its potential to revolutionize scientific operations on the lunar surface. The system enables scientists and geologists supporting the mission from Earth to gain a clearer, real-time understanding of the crew’s observations. By streaming high-definition video directly from the suit’s cameras, mission control and research teams can collaborate more effectively, making informed decisions with minimal delay.
“From a scientific perspective, what it means is all of the scientists and geologists supporting the NASA mission in real-time will have much better insight into what the crew is seeing,” Ralston explained. “People will connect with the mission a lot more closely when they can see it in such rich detail.”
Before being incorporated into Axiom’s spacesuits, Nokia’s LSCS system will undergo rigoroustesting during the IM-2 mission, the second robotic lunar lander mission by Intuitive Machines. This mission, scheduled for late 2024, will test the system’s ability to provide communication between the lander, a rover, and a “hopper” developed by Intuitive Machines. While the success of this mission is not a must for using LSCS on Axiom’s suits, it provides valuable insights for future Artemis missions.
Thierry Klein, president of Bell Labs Solutions Research at Nokia, noted that the technology could be adapted for future missions involving a lunar rover. Nokia is also exploring how this technology could be utilized in a commercial lunar economy over the next 10 to 15 years through its participation in DARPA’s LunA-10 study.
NASA’s commitment to developing advanced spacesuit technology is reflected in its recent $57.5 million task order to Axiom Space, part of the larger Exploration Extravehicular Activity Services (xEVAS) contract. This task order funds the integration of the LSCS technology into the Artemis suits, marking a significant milestone in the development process.
Axiom Space is now entering the critical design review (CDR) phase of suit development, a period that will continue into early 2025. “We’re approaching that point in time where the design is really solidifying,” Ralston said. He emphasized the importance of having Nokia’s technology incorporated before the CDR phase is completed, ensuring that the final design fully integrates the LSCS capabilities.

The LSCS technology is designed to be user-friendly, with seamless integration into the spacesuits. Astronauts can choose between different communication options based on their mission needs, whether it be UHF, Wi-Fi, or 4G/LTE. This flexibility allows for tailored communication strategies that can adapt to the unique challenges of each lunar mission.
Moreover, the LSCS system is built to operate efficiently at distances of up to two kilometers from the lander, meeting NASA’s requirements for the Artemis 3 mission. However, Nokia’s testing has shown that the system can potentially exceed this range in certain configurations, opening the door for even more ambitious lunar exploration activities in the future.
The collaboration between Axiom Space and Nokia is not just about enhancing communication for lunar missions; it’s part of a broader vision to establish a sustainable lunar economy. Nokia’s participation in DARPA’s LunA-10 study reflects this ambition. The studyexplores how communication networks like LSCS could support commercial activities on the moon, from mining operations to lunar tourism.
As the technology matures, it could become a critical infrastructure component for a thriving lunar economy, enabling everything from autonomous robotic operations to real-time video feeds for remote lunar workers.
The integration of Nokia’s LSCS into Axiom’s spacesuits represents a new standard in spacesuit technology. By combining cutting-edge wireless communication with robust, adaptable suit design, Axiom Space is setting the stage for a new era of lunar exploration.
The modularity of the LSCS allows for future upgrades and modifications, ensuring that the suits remain relevant as NASA and its partners push the boundaries of human exploration. This adaptability is crucial as NASA plans more complex missions, including establishing a permanent lunar base and eventually sending humans to Mars.

NASA’s ESCAPADE mission is about to make history. It is getting ready to launch Blue Origin’s New Glenn rocket from Cape Canaveral, Florida, for the first time. This important event will carry two spacecraft headed for Mars. These spacecraft are designed to study Mars’ atmosphere and magnetic fields. The twin satellites, called Blue and Gold, are on their way to Florida. This mission highlights big steps forward in both space science and private space travel.
ESCAPADE stands for Escape and Plasma Acceleration and Dynamics Explorers. This is a NASA mission. Its goal is to uncover the secrets of Mars’ atmosphere. Scientists will study the planet’s plasma and magnetic fields. Plasma is a hot, charged gas. They want to find out how atoms leave Mars’ upper atmosphere and magnetosphere. The magnetosphere is the region around a planet dominated by its magnetic field. This information will help us understand why Mars’ atmosphere is so thin. It will also show how the atmosphere has changed over time.
The twin spacecraft, Blue and Gold, are small satellites built by Rocket Lab, headquartered in Long Beach, California. These spacecraft are central to the ESCAPADE mission and have been carefully designed to perform their tasks with precision. Each satellite will orbit Mars, working in tandem to gather data that could answer fundamental questions about the planet’s atmospheric history.
The mission’s objectives are ambitious, aiming to enhance our understanding of how Mars lost its atmosphere over billions of years. Understanding these processes is critical not just for planetary science but also for future Mars exploration missions, including potential human expeditions.
Blue Origin’s New Glenn
The ESCAPADE mission is not just a milestone for NASA; it’s also a significant event for Blue Origin, the private spaceflight company founded by Jeff Bezos. The mission will be the first to launch aboard Blue Origin’s New Glenn rocket, a heavy-lift vehicle designed to compete with SpaceX’s Falcon Heavy. New Glenn is named after John Glenn, the first American astronaut to orbit Earth, and is designed to be reusable, with the first stage capable of flying up to 25 times.
Blue Origin’s New Glenn is a crucial component of NASA’s future space exploration plans, including the Artemis program, which aims to return humans to the Moon. Additionally, New Glenn will be used for several commercial missions, including launching satellites for Amazon’s Project Kuiper, a constellation of internet satellites designed to provide global broadband coverage.
Rocket Lab utilized its Photon spacecraft platform to develop the twin satellites. The Photon platform is a versatile spacecraft design that can be adapted for a wide range of missions, from Earth orbit to deep space exploration. For the ESCAPADE mission, Rocket Lab’s team in Long Beach, California, performed assembly, integration, and testing of the spacecraft at its Spacecraft Production Complex.
The Road to Mars
The journey to Mars is no small feat, and the ESCAPADE mission has faced numerous challenges along the way. Developing spacecraft capable of withstanding the harsh conditions of interplanetary travel requires extensive testing and engineering expertise. The successful completion of the Blue and Gold satellites is a testament to the dedication and skill of Rocket Lab’s team.
Rob Lillis is the principal investigator for the ESCAPADE mission. He is also the Associate Director for Planetary Science at the UC Berkeley Space Sciences Laboratory. Lillis praised the collaborative efforts that made the mission possible. He said,
The successful delivery of the spacecraft to Kennedy Space Center marks a significant milestone. It represents over three years of dedicated teamwork from individuals across the project, especially our partners at Rocket Lab.”
As the ESCAPADE mission prepares for launch, attention turns to Blue Origin’s New Glenn rocket. The success of this mission depends on the performance of New Glenn, a heavy-lift rocket that has been in development for several years. The launch window for the ESCAPADE mission begins in September 2024 and runs into October, with a placeholder date of September 29.
Blue Origin has invested heavily in the development of New Glenn, with construction taking place at the company’s factory on Merritt Island, Florida, adjacent to the Kennedy Space Center Visitor Complex. The rocket’s first stage is designed to be reusable, with plans for recovery operations at Port Canaveral after launch. The first-stage boosters will land on a platform in the Atlantic Ocean, similar to SpaceX’s Falcon 9 landings.
The ESCAPADE mission is just one of many planned launches for Blue Origin’s New Glenn. The rocket has a full manifest of commercial customers, including several flights for Amazon’s Project Kuiper. The Kuiper satellites are part of a broader effort to create a global broadband network, and the success of these missions is critical for Amazon’s ambitions in the space industry.
In addition to its commercial customers, Blue Origin is also a key partner in NASA’s Artemis program. The company is developing the Blue Moon lunar lander, which will be used to transport astronauts to the lunar surface as part of the Artemis program. The success of New Glenn is therefore crucial not just for the ESCAPADE mission but also for the future of human space exploration.
One of the key innovations of New Glenn is its reusability. The first stage of the rocket is designed to be used up to 25 times, significantly reducing the cost of access to space. Reusability has become a critical factor in the commercial space industry, with companies like SpaceX demonstrating the economic benefits of this approach.
Blue Origin has designed New Glenn to be a workhorse for both government and commercial customers. The rocket’s large payload capacity and reusability make it an attractive option for a wide range of missions, from launching satellites to deep space exploration. The success of the ESCAPADE mission will be an important test of New Glenn’s capabilities and a milestone in Blue Origin’s journey to become a leading player in the space industry.
The Launch Site: Cape Canaveral Space Force Station
The ESCAPADE mission will launch from Cape Canaveral Space Force Station’s Launch Complex 36 (LC-36), a historic site with a rich history of space exploration. LC-36 was originally used for government launches from 1962 to 2005, including missions like the Surveyor lunar lander and the Mariner probes. Blue Origin took over the lease for LC-36 in 2015 and has since invested approximately $1 billion in upgrading the pad for New Glenn launches.
Launch Complex 36 has played a significant role in the history of space exploration. It was from this pad that the Surveyor 1 mission launched in 1967, marking the first successful lunar landing by an American spacecraft. The Mariner probes, which provided humanity with its first close-up images of Mars, Venus, and Mercury, also launched from LC-36.
Blue Origin’s investment in LC-36 is a continuation of this legacy, transforming the site into a state-of-the-art launch facility for the New Glenn rocket. The pad is equipped with the latest technology to support the launch and recovery of the rocket’s reusable first stage, which will land approximately 620 miles downrange in the Atlantic Ocean.
As the launch date gets closer, final preparations are happening at LC-36. The twin spacecraft, named Blue and Gold, need to be checked and tested after transportation. These checks will take place in a cleanroom at Kennedy Space Center. A cleanroom is a special room with very low levels of dust and germs. After these inspections, the spacecraft will be encapsulated for launch. Encapsulation means covering the spacecraft to protect them. This process is important to keep the spacecraft safe during the harsh conditions of launch and their trip to Mars.
Once covered, the spacecraft will join with the New Glenn rocket at LC-36. Workers will attach the spacecraft to the rocket’s payload adapter. The payload adapter helps connect the spacecraft to the rocket. The spacecraft will then be secured inside the payload fairing. The payload fairing protects the spacecraft while the rocket rises. Finally, the whole launch vehicle will go through several last checks to make sure it’s ready to fly.
The ESCAPADE mission is expected to reach Mars in approximately 11 months after launch, with the twin spacecraft entering highly elliptical orbits around the planet. These orbits will allow the spacecraft to study Mars’ atmosphere and magnetosphere from different altitudes, providing a comprehensive view of the processes at work.
Once at Mars, the Blue and Gold satellites will work together to map the structure of Mars’ magnetosphere and observe how it interacts with the solar wind. This data will help scientists understand the processes that have stripped away much of Mars’ atmosphere over time, leaving the planet with the thin, cold atmosphere we see today.
Mission Duration and Goals
The primary mission duration is expected to be one year, during which the spacecraft will conduct a series of experiments and observations. The data collected will be transmitted back to Earth, where scientists will analyze it to build a more detailed understanding of Mars’ atmospheric processes.
One of the key goals of the ESCAPADE mission is to determine how much atmospheric escape is driven by Mars’ magnetosphere and how much is caused by interactions with the solar wind. By studying these processes in detail, scientists hope to gain insights into how atmospheres evolve on planets with weak magnetic fields, which could have implications for our understanding of other planets and exoplanets.
Potential Discoveries
The ESCAPADE mission could lead to several important discoveries about Mars and its history. By mapping the planet’s magnetosphere, scientists may be able to identify regions where the atmosphere is being lost most rapidly. This information could help inform future missions to Mars, including those that may involve human exploration.
The mission could also provide clues about the early history of Mars and how it lost its once-thicker atmosphere. Understanding these processes is critical for piecing together the history of the solar system and for assessing the habitability of other planets.
The upcoming launch of NASA’s ESCAPADE mission aboard Blue Origin’s New Glenn rocket marks a significant milestone in space exploration. This mission not only advances our understanding of Mars’ atmospheric and magnetic properties but also represents the dawn of a new era in commercial spaceflight with the debut of Blue Origin’s heavy-lift vehicle. As we look ahead to the journey of the Blue and Gold spacecraft to the Red Planet, the mission stands as a testament to the collaborative efforts of NASA, Rocket Lab, and Blue Origin in pushing the boundaries of what is possible in space exploration.

NASA Shuts Down NEOWISE Telescope as Sun Draws It to a Fiery End
NEOWISE, originally WISE, was a NASA space telescope designed to detect infrared signals from space objects, including near-Earth asteroids and comets.
Launched in 2009, the telescope vastly outlived its intended seven-month mission, operating for over 15 years and making significant discoveries.
NEOWISE detected over 200 previously unknown near-Earth objects (NEOs), including 25 new comets and provided valuable data on 44,000 other objects.
The telescope was retired on July 31, 2024, due to the increased solar activity that will eventually drag it into Earth’s atmosphere, where it will burn up.
A successor mission, the NEO Surveyor, is planned for launch in 2027 to continue the work of NEOWISE, with more advanced technology to detect asteroids near the sun’s glare.
The end of NEOWISE leaves a temporary gap inplanetary defense, but ground-based telescopes will continue to monitor near-Earth objects.
NASA Shuts Down NEOWISE Telescope as Sun Draws It to a Fiery End
NASA’s NEOWISE telescope, a remarkable instrument that spent 15 years scanning the skies for near-Earth objects, has reached the end of its journey. Originally launched as the Wide-field Infrared Survey Explorer (WISE) in 2009, the telescope far exceeded its initial expectations, making groundbreaking discoveries and providing critical data for planetary defense. As the sun’s activity reaches its peak, the satellite is being pulled towards Earth, where it will ultimately burn up in the atmosphere, marking the end of an era for NASA’s asteroid-hunting efforts.
The Origins and Evolution of NEOWISE
NEOWISE began its life as WISE, a mission with a relatively simple goal: to map the entire sky in infrared light. Infrared astronomy allows scientists to see objects that are otherwise invisible in visible light, particularly cold and distant objects in space. When WISE was launched, its primary mission was to observe distant galaxies, stars, and other cosmic phenomena, contributing to our understanding of the early universe.
However, the capabilities of WISE soon exceeded expectations. Its sensitivity to infrared light made it an excellent tool for detecting near-Earth objects (NEOs), such as asteroids and comets that might pose a threat to our planet. Recognizing this potential, NASA extended WISE’s mission in 2010 and rebranded it as NEOWISE in 2013, focusing its efforts entirely on planetary defense.
NEOWISE’s Mission and Achievements
Over the course of its extended mission, NEOWISE became an invaluable asset for NASA. The telescope detectedmore than 200 previously unknown near-Earth objects, including 25 new comets. It also gathered data on 44,000 other objects within our solar system, greatly enhancing our understanding of the space environment surrounding Earth.
One of NEOWISE’s most notable discoveries was the detection of comet C/2020 F3 (NEOWISE), a bright and spectacular comet that became visible to the naked eye in July 2020. This discovery captured the public’s imagination and highlighted the telescope’s enduring value, even as it approached the end of its operational life.
NEOWISE’s data has been crucial for mapping the orbits of near-Earth asteroids, which helps scientists assess the potential threat these objects might pose to our planet. According to NASA, more than 34,000 near-Earth asteroids have been cataloged, and none of them are expected to collide with Earth in the next 100 years.
The Inevitable End of NEOWISE
Despite its many successes, NEOWISE’s mission could not last forever. The spacecraft was originally designed for a seven-month mission, and although it managed to continue functioning for 15 years, the increasing activity of the sun, known as solar maximum, posed a significant threat. Without propellant to raise its orbit, NEOWISE has been gradually falling towards Earth, and it is expected to reenter the atmosphere and burn up by the end of 2024.
Amy Mainzer, a professor at the University of California, Los Angeles, and the principal investigator for both NEOWISE and its planned successor, NEO Surveyor, expressed her gratitude for the telescope’s extended mission. “This telescope has really outlived its original lifespan,” she said in an interview with Live Science. “We got so much more out of it than we were expecting to get.”
While the end of NEOWISE marks a significant loss for NASA’s planetary defense efforts, the space agency is already planning the next phase of its mission to protect Earth from potential asteroid impacts. The NEO Surveyor is a next-generation space telescope designed to continue the work of NEOWISE, with even greater capabilities.
Scheduled for launch no sooner than 2027, the NEO Surveyor will perform full-sky scans every two weeks, significantly improving the detection of near-Earth objects. One of the key features of this new telescope will be its ability to search for asteroids located near the sun’s glare, a region that has long been considered a blind spot in planetary defense.
To achieve this, the NEO Surveyor will be equipped with a purpose-built solar shade, allowing it to observe asteroids that are difficult to detect with ground-based telescopes. This capability will be crucial for identifying “planet-killer” asteroids that could potentially impact Earth with little warning.
A Temporary Gap in Planetary Defense
With the shutdown of NEOWISE, there will be a temporary gap in NASA’s space-based planetary defense capabilities. Currently, there is no other space telescope dedicated entirely to hunting for near-Earth objects. However, NASA and the astronomical community are not entirely defenseless. Powerful ground-based observatories, such as the Catalina Sky Survey in Arizona and Pan-STARRS in Hawaii, continue to play a vital role in monitoring the skies for potential threats.
The Importance of Planetary Defense
The work of NEOWISE and the upcoming NEO Surveyor highlights the critical importance of planetary defense. While the odds of a catastrophic asteroid impact are low, the potential consequences are so severe that vigilance is necessary. The extinction of the dinosaurs is a stark reminder of what can happen when a large asteroid collides with Earth.
NASA works hard to protect our planet from cosmic threats. They focus on planetary defense. This includes watching near-Earth objects. NASA also looks for ways to move or destroy dangerous asteroids. One of their projects is the Double Asteroid Redirection Test (DART). In 2022, DART successfully changed an asteroid’s orbit. This shows that technology can help reduce these risks.
As NEOWISE prepares to make its final descent into Earth’s atmosphere, it’s important to reflect on the legacy of this remarkable space telescope. Originally intended for a brief mission to observe distant galaxies, NEOWISE exceeded all expectations, becoming a cornerstone of NASA’s planetary defense efforts. Its discoveries have deepened our understanding of the solar system and provided valuable data that will continue to inform future missions.
The impending launch of the NEO Surveyor promises to build on NEOWISE’s achievements, offering even greater capabilities for detecting and monitoring near-Earth objects. While there may be a temporary gap in space-based planetary defense, the work of ground-based observatories and the eventual deployment of the NEO Surveyor will ensure that Earth remains vigilant against the threat of asteroid impacts.

New Geological Connection Between Earth and Venus Discovered by Scientists
Scientists have discovered a surprising geological connection between Earth and Venus, suggesting that despite the absence of plate tectonics on Venus, the planet may have experienced similar geological processes as Earth. This discovery opens new avenues for understanding planetary evolution and raises questions about Venus’s past habitability.
Summary
Venus is often called Earth’s “sister planet” due to their similarities in size, mass, and composition.
Unlike Earth, Venus lacks plate tectonics, traditionally believed to be essential for significant geological activity.
New research suggests that Venus’s Ishtar Terra, a highland region, may have formed through processes similar to those that created Earth’s ancient cratons.
Cratons are the stable, ancient cores of continents on Earth, some dating back over 2.5 billion years.
The discovery challenges previous assumptions about Venus’s geological history, indicating that the planet may have been more geologically active in the past.
This finding raises questions about the potential for past habitability on Venus and the role of similar geological processes in planetary evolution.
Understanding Venus’s geological history is crucial for comparative planetology and could provide insights into Earth’s own evolution.
Future missions to Venus should focus on gathering more data about its geology, atmosphere, and potential for past habitability.
The study highlights the need for continued exploration of Venus to unlock the secrets of its past and its implications for planetary science.
Venus: Earth’s Geological Twin?
Venus has long fascinated scientists due to its many similarities with Earth. Both planets are similar in size, mass, and composition, earning Venus the nickname “Earth’s sister planet.” However, the two planets have changed a lot in their geological and atmospheric development. Earth is a dynamic planet. It has active plate tectonics, which means its surface is made up of large plates that move and cause earthquakes. Venus, on the other hand, has been considered inactive for a long time. New research has found a surprising connection between the geology of Earth and Venus. This discovery challenges what we thought we knew about Venus’s history and how it relates to Earth.
Venus and Earth
Venus and Earth look very similar at first. Both are called terrestrial planets. This means they are mostly made of rock and metal. Both planets have thick atmospheres filled with carbon dioxide. They are also similar in size and density. This means they have almost the same amount of mass and take up nearly the same amount of space. However, Venus and Earth have evolved in very different ways.
Earth is a lively and ever-changing planet. Its surface changes all the time due to plate tectonics. In plate tectonics, the outer shell of the Earth, known as the lithosphere, is made up of large pieces called plates. These plates move and interact with each other. This movement forms continents, mountains, and oceans. It also creates many different geological features. Plate tectonics are very important in controlling Earth’s climate. They help create the right conditions for life to exist.
Venus, on the other hand, is very different. Thick clouds of sulfuric acid cover the planet’s surface. The atmospheric pressure is extremely high, more than 90 times that of Earth’s. Surface temperatures on Venus reach a blistering 900 degrees Fahrenheit (475 degrees Celsius). This heat is hot enough to melt lead. Because of these extreme conditions, scientists see Venus as a hostile place. They believe it has little or no tectonic activity, which means the planet’s surface does not change much through movements of the crust.
Ishtar Terra
Recent research has cast doubt on the long-held belief that Venus is a geologically dead planet. A team of scientists has focused their attention on Ishtar Terra, one of the planet’s three major highland regions. Ishtar Terra, located near Venus’s north pole, is a vast plateau that includes some of the planet’s most prominent geological features, including the Maxwell Montes mountain range, which rises nearly 11 kilometers (6.8 miles) above the surrounding plains.
Ishtar Terra’s topography is strikingly similar to Earth’s highland regions, such as the Tibetan Plateau. This similarity has led scientists to wonder whether Ishtar Terra may have formed through processes analogous to those that shaped Earth’s ancient cratons. Cratons are the ancient, stable cores of continents on Earth, some of which date back over 2.5 billion years. These geological formations are among the oldest rocks on our planet and provide crucial insights into Earth’s early history.
The recent study, published in the journal Nature Geoscience, used advanced computer simulations and data from NASA’s Magellan spacecraft to explore the formation of Ishtar Terra. The researchers discovered that the highland region may have been formed by processes similar to those that created Earth’s cratons. Specifically, they found evidence that powerful upwellings of molten rock from Venus’s interior could have caused the crust to thicken and rise, creating a plateau-like structure.
This finding is surprising because it suggests that Venus, despite lacking plate tectonics, may have experienced similar geological processes as Earth. The absence of plate tectonics on Venus has long been thought to limit the planet’s ability to generate significant geological features. However, the discovery of a thick, craton-like crust in Ishtar Terra challenges this assumption and opens new possibilities for understanding Venus’s geological history.

Implications for Planetary Evolution
The implications of this discovery are profound. If Venus did indeed experience a period of intense geological activity, it raises important questions about the planet’s past. For example, could Venus have once had conditions similar to early Earth, including the presence of oceans and a more temperate climate? If so, what caused Venus to undergo such a dramatic transformation into the inhospitable world we see today?
Understanding what led to Venus’s current state is important. It helps us learn about how planets change over time. This knowledge is also useful when studying exoplanets, which are planets outside our solar system. Scientists want to know what makes a planet habitable, or able to support life. Venus might have important hints about how Earth developed early on. It could also show us the potential for life on other planets.
The Role of Ishtar Terra in Venus’s Geological History
To better understand the significance of Ishtar Terra, it’s essential to examine the region’s geological features in more detail. Ishtar Terra is divided into several distinct regions, each with its own unique characteristics. These include the Maxwell Montes mountain range, the Lakshmi Planum plateau, and the surrounding plains.
Maxwell Montes is the highest mountain range on Venus, rising to an elevation of nearly 11 kilometers (6.8 miles) above the surrounding terrain. The range is composed of heavily deformed rocks, indicating a complex geological history. The presence of Maxwell Montes within Ishtar Terra suggests that the region has experienced significant tectonic forces, despite the lack of plate tectonics on Venus.
Lakshmi Planum
Lakshmi Planum is a vast, elevated plateau within Ishtar Terra, covering an area of approximately 2 million square kilometers. The plateau is characterized by smooth lava flows, indicating a history of volcanic activity. Two large shield volcanoes, Colette and Sacajawea, are also located within Lakshmi Planum. These features further suggest that Ishtar Terra has been shaped by processes similar to those that formed Earth’s cratons.
The Plains
Surrounding Ishtar Terra are vast plains, which are relatively smooth and featureless compared to the highland regions. These plains are likely the result of extensive lava flows, which have covered much of Venus’s surface over time. The transition from the highland regions to the plains provides clues about the geological processes that have shaped Venus’s surface.
Comparing Earth and Venus: Cratons and Highlands
To better understand the connection between Earth and Venus, it’s helpful to compare the geological features of the two planets. On Earth, cratons are the ancient cores of continents, and they are typically found in the center of tectonic plates. These cratons are composed of some of the oldest rocks on the planet and provide valuable insights into Earth’s early history.
Cratons are characterized by their stability and resistance to tectonic forces. They are composed of thick, rigid lithosphere, which helps them withstand the forces that reshape other parts of the Earth’s crust. This stability allows cratons to preserve a record of geological processes that occurred billions of years ago.
The discovery of a craton-like structure in Ishtar Terra suggests that Venus may have experienced similar geological processes in its past. The thick, stable crust of Ishtar Terra could be the result of upwellings of molten rock from Venus’s interior, similar to the processes that formed Earth’s cratons. This finding challenges the long-held assumption that plate tectonics are necessary for significant geological activity and suggests that other processes may be at work on Venus.
Venus’s Lithosphere
One of the key differences between Earth and Venus is the thickness of their lithospheres. Earth’s lithosphere can be as thick as 200 kilometers (124 miles) in some regions, while Venus’s lithosphere is much thinner, estimated to be between 50 and 100 kilometers (31 to 62 miles) thick. This thinner lithosphere may have significant implications for the planet’s geological history.
The thin outer layer of Venus, called the lithosphere, is likely more prone to bending and breaking than Earth’s thicker outer layer. This could be why we see large volcanic features on Venus. For example, there are shield volcanoes in an area called Lakshmi Planum. The surface of Venus is also covered with extensive lava flows. This thin lithosphere suggests that Venus has likely gone through intense periods of geological activity in the past. This happened even though it doesn’t have the same plate movement as Earth.
The Role of Volcanism in Venus’s Geological History
Volcanism has significantly shaped Venus’s surface. Large shield volcanoes are spread across the planet. Some of these volcanoes are among the largest in the solar system. Shield volcanoes have broad, gently sloping shapes. This shape is created by the eruption of lava that flows easily.
The presence of shield volcanoes in Ishtar Terra suggests that the region has been shaped by volcanic activity. This is further supported by the smooth lava flows that characterize Lakshmi Planum. The discovery of a craton-like structure in Ishtar Terra, combined with evidence of extensive volcanism, suggests that Venus’s geological history may be more complicated than previously thought.
Comparative Planetology: Lessons from Venus
The discovery of a geological connection between Earth and Venus has significant implications for the field of comparative planetology. Comparative planetology is the study of planets by comparing their characteristics and evolution. By studying the similarities and differences between planets, scientists can gain insights into the processes that shape planetary systems.
Venus and Earth provide a unique opportunity for comparative planetology. Despite their many similarities, the two planets have followed dramatically different evolutionary paths. Understanding why this divergence occurred could provide valuable insights into the factors that influence planetary evolution.
The Search for Past Habitability on Venus
One of the most intriguing questions raised by the discovery of a geological connection between Earth and Venus is the possibility of past habitability on Venus. If Venus once had conditions similar to early Earth, including the presence of liquid water, it raises the possibility that the planet could have supported life in its distant past.
Recent studies have suggested that Venus may have had a more temperate climate in its early history, with liquid water oceans that persisted for billions of years. If true, this would make Venus one of the most Earth-like planets in the solar system. However, at some point in its history, Venus underwent a dramatic transformation, leading to the extreme conditions we see today.
Understanding the factors that led to Venus’s current state is crucial for assessing the planet’s potential for past habitability. The discovery of a craton-like structure in Ishtar Terra suggests that Venus may have experienced similar geological processes as Earth, which could have played a role in the planet’s early climate and habitability.
Future Exploration of Venus
The discovery that Earth and Venus have a geological connection shows we need to explore Venus more. Venus is our closest neighbor planet, but we still know very little about it. It is one of the least explored planets in the solar system. The planet’s surface has very harsh conditions. These tough conditions make it hard to collect detailed information about its rocks, air, and history.
Future missions to Venus, such as NASA’s VERITAS mission and the European Space Agency’s EnVision mission, aim to address these challenges by providing high-resolution data about the planet’s surface and subsurface. These missions will help scientists better understand the geological processes that have shaped Venus and provide crucial insights into its past habitability.
The discovery of a new geological connection between Earth and Venus challenges our understanding of the two planets and their divergent evolutionary paths. Despite the absence of plate tectonics on Venus, the planet may have experienced similar geological processes as Earth, leading to the formation of craton-like structures in Ishtar Terra. This finding raises important questions about Venus’s past habitability and the factors that shaped its current state.

The Nancy Grace Roman Space Telescope: NASA’s Latest Space Marvel
The Nancy Grace Roman Space Telescope will revolutionize our understanding of the universe by exploring exoplanets, dark energy, and the cosmic dawn, all while continuing the legacy of the Hubble Space Telescope.
Summary
The Nancy Grace Roman Space Telescope will launch in 2027.
It features a 2.4-meter primary mirror, the same size as Hubble’s.
The Wide Field Instrument will capture images with a field of view 100 times greater than Hubble’s.
Before the Hubble Space Telescope, our view of the cosmos was limited by Earth’s atmosphere. When Hubble was launched, it transformed our understanding of the universe. Now, NASA’s Nancy Grace Roman Space Telescope is poised to do the same, offering a new perspective on the universe.
The Roman Space Telescope will feature a 2.4-meter primary mirror, the same size as Hubble’s. However, its capabilities will far exceed those of its predecessor. A single image from the Roman telescope will contain the detail of 100 Hubble images, thanks to its Wide Field Instrument, which has a field of view 100 times greater than Hubble’s infrared instrument.
After its launch in 2027, the telescope is expected to address fundamental questions about exoplanets, dark energy, and the cosmic dawn—the period when the first stars and galaxies formed. NASA has ambitious plans for this telescope, and its potential discoveries could reshape our understanding of the universe.
The Roman Telescope’s 100,000 New Exoplanets
The Roman Space Telescope will survey the Milky Way, taking observations every 15 minutes for over a year. This will result in a massive amount of data, enabling astronomers to track changes in the brightness of stars. These changes can reveal the presence of exoplanets, rogue planets, isolated black holes, and more.
The Roman Space Telescope is expected to increase the number of known exoplanets from around 5,000 to approximately 100,000 in the next five to ten years. This incredible leap in discovery is made possible by the telescope’s Coronagraph Instrument—the first active coronagraph to fly in space.
The Roman Coronagraph will advance scientists’ ability to directly image planets and disks around other stars. Coronagraphs work by blocking light from a bright object, like a star, making it easier to see a faint object, such as a planet near it.
The Roman Coronagraph is designed to detect planets 100 million times fainter than their stars, making it 100 to 1,000 times more effective than existing space-based coronagraphs. This instrument will be capable of directly imaging reflected starlight from a planet similar in size and temperature to Jupiter, providing unprecedented insights into distant worlds.
The Roman Telescope and the Cosmic Dawn
Following the Big Bang, the universe was dark for approximately 380,000 to 200 million years—a period known as the cosmic dark ages. During this time, stars began to form, but their light was absorbed by neutral atoms, creating a kind of obscuring fog. Eventually, these atoms broke apart, allowing the light of stars to travel freely and illuminate the universe. This transition from dark to light is called the cosmic dawn.
The Roman Space Telescope will play a crucial role in studying this period, helping astronomers understand how the first stars and galaxies formed and evolved. Roman’s wide field of view will allow it to quickly identify the densest regions of space where more “fog” is being cleared, making it a key mission for probing early galaxy evolution and the cosmic dawn.
Here is an artist’s idea of the cosmic dawn. The cosmic dawn is the time when the first stars and galaxies started to form. This picture shows how the universe may have looked when it was less than a billion years old. The image is from NASA, ESA, and an artist named A. Schaller for the Space Telescope Science Institute (STScI).
Roman will also help determine how common quasars were during this time and whether certain types of galaxies played a larger role in clearing the fog. By studying these early structures, Roman will provide insights into the processes that shaped the universe as we know it today.
The Roman Space Telescope and Dark Energy
One of the most profound mysteries in modern astrophysics is the nature of dark energy—the force that makes up about 68% of the total energy content of the universe and is responsible for the acceleration of its expansion. The Roman Space Telescope is designed to study dark energy by mapping the distribution of matter and measuring distant supernovae.
Roman’s wide field of view will allow astronomers to take a bigger picture of the universe, helping them understand how dark energy might have changed over time and how it influences the structure and evolution of the cosmos.
In the past, the universe expanded more slowly. Today, it expands faster. Dark energy causes this rapid growth. NASA’s Scientific Visualization Studio provides an image illustrating this concept.
The Nancy Grace Roman Space Telescope is named after Nancy Grace Roman, an American astronomer who played a pioneering role in the development of space-based astronomy. Often referred to as the “Mother of the Hubble Space Telescope,” Roman was a trailblazer in a male-dominated field and made significant contributions to our understanding of the universe.
Roman was born in 1925 and showed an early interest in astronomy. She pursued her passion despite the challenges she faced as a woman in science. After earning her Ph.D., Roman became known for her work in stellar spectroscopy and the motion of stars. She joined NASA in 1959, becoming the first Chief of Astronomy in the Office of Space Science, where she was instrumental in advocating for and planning space telescopes, including the Hubble Space Telescope.

From uncovering thousands of new exoplanets to probing the cosmic dawn and exploring the mysterious nature of dark energy, this telescope is poised to make groundbreaking discoveries that will shape our understanding of the cosmos for decades to come.
Europa Clipper Mission: Exploring Jupiter’s Icy Moon
The Europa Clipper mission is a groundbreaking initiative by NASA aimed at determining the habitability of Jupiter’s icy moon, Europa. Scheduled to launch in October 2024, the spacecraft will perform nearly 50 flybys of Europa, gathering detailed measurements to understand the moon’s ice shell, ocean, composition, and geology. This mission is critical in the search for life beyond Earth.
The Europa Clipper mission, spearheaded by NASA, is set to revolutionize our understanding of one of Jupiter’s most intriguing moons, Europa. This mission aims to determine whether there are places beneath Europa’s icy surface that could support life, thereby expanding our knowledge of potentially habitable environments beyond Earth.
Europa, one of Jupiter’s largest moons, has long intrigued scientists due to its strong evidence of a subsurface ocean beneath its icy crust. This ocean is believed to contain more water than all of Earth’s oceans combined, making Europa a prime candidate in the search for extraterrestrial life. The Europa Clipper mission, scheduled for launch in October 2024, aims to explore this ocean world and uncover its secrets.
Mission Objectives
The Europa Clipper mission has three primary science objectives:
Determine the Thickness of Europa’s Icy Shell: Understanding the thickness of the ice shell and the characteristics of the ocean beneath it is crucial. Scientists aim to discover if there is liquid water within and beneath the shell and estimate the size, saltiness, and other qualities of Europa’s ocean.
Investigate Europa’s Composition: The mission will investigate the composition of Europa’s ocean to determine if it has the necessary ingredients to support life.
Characterize the Geology of Europa: Scientists will study how Europa’s surface features formed and identify any signs of recent geological activity, such as sliding crust plates or plumes venting water into space.
Pre-Project Planning (Pre-Phase A) Before selecting a mission, planners come up with different mission ideas. For example, they considered a spacecraft to orbit Europa and another to land on Europa. Another idea was for a spacecraft to orbit Jupiter in sync with Europa’s orbit. This would allow for flybys of Europa and less exposure to Jupiter’s intense radiation. The idea with strong science potential, lower cost, and less risk was chosen in the end.
Spacecraft Design
Largest Planetary Mission Spacecraft
Europa Clipper is NASA’s largest spacecraft developed for a planetary mission. It features massive solar arrays designed to collect enough Sunlight to power the spacecraft as it operates in the distant Jupiter system, more than five times as far from the Sun as Earth. The spacecraft stands about 16 feet (5 meters) tall, with a span of over 100 feet (30.5 meters) when its arrays are fully deployed. It has a dry mass of 7,145 pounds (3,241 kg).
Designed for Jupiter’s Tough Radiation Environment
Given the intense radiation environment around Europa, the spacecraft’s electronics are enclosed in a thick-walled radiation vault made of titanium and aluminum. This design, first used by NASA’s Juno spacecraft, shields the electronics from most high-energy atomic particles, dramatically slowing down their degradation.
Science Instruments
Europa Clipper is equipped with a suite of advanced science instruments designed to explore Europa in unprecedented detail.
Imagers / Cameras
Europa Imaging System (EIS): This system includes a wide-angle and a narrow-angle camera, each with an eight-megapixel sensor. These cameras will produce high-resolution color and stereoscopic images of Europa, study geologic activity, measure surface elevations, and provide context for other instruments.
Europa Thermal Emission Imaging System (E-THEMIS): Using infrared light, this thermal imager will identify warmer regions on Europa where liquid water might be near the surface or have erupted onto the surface.
Imagers / Spectrometry
Europa Ultraviolet Spectrograph (Europa-UVS): By collecting ultraviolet light with a telescope, this spectrograph will determine the composition of Europa’s atmospheric gases and surface materials, and search for signs of plume activity.
Mapping Imaging Spectrometer for Europa (MISE): This infrared spectrometer will map the composition and distribution of ices, salts, organics, and the warmest hotspots on Europa.
Plasma & Magnetic Field
Europa Clipper Magnetometer (ECM): The magnetometer will study Europa’s magnetic field, confirm the presence of an ocean, measure its depth and salinity, and study the moon’s ionized atmosphere.
Plasma Instrument for Magnetic Sounding (PIMS): PIMS will distinguish distortions in Europa’s magnetic field, revealing information about the moon’s ocean.
Radar for Europa Assessment and Sounding: Ocean to Near-surface (REASON): This ice-penetrating radar will probe Europa’s icy shell, studying its structure and thickness, and the topography and composition of the surface.
Chemical Analysis
MAss Spectrometer for Planetary EXploration/Europa (MASPEX): This mass spectrometer will analyze gases in Europa’s faint atmosphere and possible plumes, studying the chemistry of the subsurface ocean.
SUrface Dust Analyzer (SUDA): SUDA will identify the chemistry and area of origin of material ejected into space by tiny meteorites or plumes, providing clues to Europa’s ocean salinity.
