Two NASA astronauts on board Boeing’s Starliner spacecraft may be forced to stay in space until 2025 due to propulsion system issues with the spacecraft.

Summary

  • Two NASA astronauts, Butch Wilmore and Sunita Williams, are currently on the International Space Station (ISS) after their Boeing Starliner spacecraft experienced propulsion system malfunctions.
  • The malfunctions included stalled thrusters, helium leaks, and a faulty propellant valve.
  • Due to the problems, NASA is considering using SpaceX’s Crew Dragon capsule to bring the astronauts home in February 2025.
  • This would require delaying SpaceX’s Crew-9 mission which was originally planned for August 2024.
  • Boeing is still investigating the cause of the Starliner thruster issues.

Boeing Starliner: Stuck in Space Until 2025?

In June 2024, two NASA astronauts, Butch Wilmore and Sunita Williams, embarked on what was supposed to be a routine eight-day mission to the International Space Station (ISS) aboard Boeing’s Starliner capsule. However, their journey has taken an unexpected turn. Due to critical technical issues with the Starliner, including malfunctioning thrusters and helium leaks, their return to Earth has been significantly delayed.

Technical Challenges with the Starliner

The current predicament with the Starliner stems from a series of technical problems encountered shortly after launch. These problems include:

  • Malfunctioning Thrusters: Five of the Starliner’s maneuvering thrusters broke. This made it hard for the spacecraft to move and steer properly.
  • Helium Leaks: Engineers also detected leaks in the spacecraft’s helium valves, which are critical for proper thruster function.

These issues have rendered the Starliner unfit for a safe return journey to Earth at present. Consequently, NASA is exploring alternative options to bring the astronauts home safely.

Terraforming Mars with Tiny Metal Rods The Future of Making the Red Planet Habitable

Terraforming Mars with Tiny Metal Rods: The Future of Making the Red Planet Habitable

  • Terraforming Mars involves altering its environment to make it more suitable for Earth-like life.
  • A new method proposes using glitter-sized iron and aluminum rods to increase the planet’s temperature by around 30°C.
  • Micro-metal rods can be mined from Mars itself, reducing the need to import materials from Earth.
  • The concept is 5000 times more efficient than other proposed methods like engineered greenhouse gases.
  • Ethical concerns arise around altering another planet’s atmosphere, especially given our limited knowledge of Mars’ deep surface.

Summary

  • Terraforming is the process of modifying a planet’s environment to make it more Earth-like.
  • Mars currently has an average surface temperature of -65°C, making it inhospitable for Earth-like life.
  • Previous proposals for warming Mars included space mirrors and methane pumping, but these were resource-intensive.

Terraforming Mars with Tiny Metal Rods

Terraforming, the concept of transforming a planet’s environment to resemble Earth’s, has long been a subject of fascination and debate. Mars, our neighboring Red Planet, is the prime candidate for such an undertake. However, the challenges are enormous, given its harsh environment with temperatures averaging -65°C (-85°F). Scientists have proposed various methods to warm Mars, making it more hospitable for life, but most of these methods are resource-intensive and difficult to implement.

A recent study led by Edwin Kite at the University of Chicago presents a novel approach to this problem: using tiny rods of iron and aluminum to warm Mars. This method could be a game-changer in the field of planetary engineering, offering a more efficient and feasible way to terraform Mars.

The Science Behind Terraforming Mars

Mars is a cold, barren planet with a thin atmosphere composed mostly of carbon dioxide. Its surface temperature ranges from -140°C (-220°F) during winter at the poles to 20°C (70°F) during summer at the equator, but the average temperature is a frigid -65°C. The thin atmosphere means that even if the surface heats up during the day, the heat quickly escapes at night.

The idea of terraforming Mars revolves around changing these conditions to create a more Earth-like environment, capable of supporting life. The key challenge is raising the planet’s temperature and atmospheric pressure to allow liquid water to exist, a fundamental requirement for life as we know it.

Previous Proposals

Several ideas have been floated over the years to warm Mars:

  1. Space Mirrors: Large mirrors in space could reflect sunlight onto Mars’ surface, increasing the temperature. However, the logistics and costs involved in building and deploying such mirrors are staggering.
  2. Greenhouse Gases: Pumping greenhouse gases like methane into Mars’ atmosphere could trap more heat. But this method would require massive amounts of methane, which would need to be transported from Earth or synthesized on Mars, both of which are currently impractical.
  3. Nuclear Explosions: Another radical idea involves using nuclear explosions to heat Mars’ poles, releasing trapped CO2 and thickening the atmosphere. This idea is controversial, not least because of the potential dangers and ethical concerns.

Each of these methods has significant drawbacks, making the search for a more efficient solution critical.

The New Approach: Tiny Metal Rods

Edwin Kite and his team propose a new method that could be much more practical and efficient. The idea is to release tiny rods of iron or aluminum, each about 9 micrometers long and 160 nanometers wide, into Mars’ atmosphere. These rods would be mined from Mars’ surface, eliminating the need to transport materials from Earth.

Once released, these rods would be carried by wind into the upper atmosphere, where they would remain for about a decade. Their small size allows them to trap heat effectively, while still allowing sunlight to pass through. The trapped heat would raise the planet’s surface temperature by about 30°C, enough to melt ice and support microbial life.

Kite and his colleagues used climate models to simulate the effects of releasing these rods. Their results showed that the rods could increase the temperature by about 30°C in a matter of months to a decade, depending on how quickly the particles are dispersed. This increase in temperature would also lead to a rise in atmospheric pressure, potentially allowing liquid water to exist on the surface.

The warming effect is critical because it could create conditions suitable for microbial life. Microbes could play a vital role in terraforming Mars, as some bacteria are capable of producing oxygen, further transforming the planet’s atmosphere over time.

Terraforming Mars with Tiny Metal Rods The Future of Making the Red Planet Habitable

Practical Considerations

One of the biggest challenges in terraforming Mars is the sheer amount of material required. However, Kite’s approach is surprisingly efficient. To achieve the necessary warming, only about 700,000 cubic meters of metal rods would need to be released each year. This is equivalent to just 1% of Earth’s total annual metal production, making it a feasible target.

The fact that these materials could be mined directly on Mars is another significant advantage. This reduces the logistical challenges and costs associated with transporting materials from Earth. However, mining on Mars is not without its challenges, and significant technological advancements would be needed to extract and process these metals on the planet.

One of the uncertainties in this method is how the tiny rods would interact with Mars’ atmosphere, particularly with water vapor. There is a possibility that water molecules could cling to the rods, causing them to fall back to the surface as rain. This would reduce the warming effect, as the rods would no longer be in the atmosphere to trap heat.

This interaction needs to be carefully studied, as it could impact the overall effectiveness of the terraforming process. If the rods do indeed fall out of the atmosphere too quickly, alternative strategies might be needed, such as continuously replenishing the rods or finding ways to prevent water from clumping around them.

Ethical Considerations

While the idea of terraforming Mars is exciting, it raises important ethical questions. Mars is a pristine environment, and we know very little about its deep surface and potential for existing life forms. By altering its atmosphere, we could be destroying any chance of discovering native Martian life.

There is also the issue of planetary protection. International agreements currently require that we avoid contaminating other planets with Earth life. Terraforming Mars would almost certainly violate these agreements, as it would involve introducing Earth-based microbes and potentially altering the planet’s environment irreversibly.

Conclusion

Terraforming Mars is one of the most ambitious ideas in human history. It involves changing the planet’s harsh environment to make it more like Earth. The idea of turning a barren, frozen world into a second Earth is exciting. However, it is also very challenging. One new proposal is to use tiny metal rods to warm Mars. This approach seems promising and could help make the dream of terraforming Mars come true.

However, before we can proceed, we must carefully consider the ethical implications and ensure that we are not causing irreversible harm to a planet we are only just beginning to understand. With careful planning, international collaboration, and ongoing research, terraforming Mars could one day become a reality, offering a new frontier for human exploration and habitation.

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.
  • The telescope is expected to discover up to 100,000 exoplanets.
  • Roman will explore dark energy, the force driving the acceleration of the universe’s expansion.
  • It will also investigate the cosmic dawn, the era when the first stars and galaxies formed.
  • The Coronagraph Instrument on Roman will allow direct imaging of exoplanets.
  • The telescope is named after Nancy Grace Roman, the “Mother of the Hubble Space Telescope.”

Meet the Nancy Grace Roman Space Telescope

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.

Watch an introductory video about the Nancy Grace Roman Space Telescope.

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.

Learn more about the Roman Coronagraph Instrument.

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.

The Nancy Grace Roman Space Telescope NASA's Latest Space Marvel
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).

Read more about how the Roman Space Telescope will illuminate the cosmic dawn.

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.

Europa Clipper Mission: A Detailed Exploration

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:

  1. 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.
  2. 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.
  3. 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.
Europa Clipper Mission Exploring Jupiter’s Icy Moon
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.

Axiom Space Pioneering the Future of Commercial Spaceflight

History and Founding

Axiom Space was founded in 2016 by Michael T. Suffredini and Kam Ghaffarian. Suffredini, previously the program manager for the International Space Station (ISS) from 2005 to 2015, brought extensive experience in space operations. Ghaffarian, an engineer and entrepreneur, sold his company, Stinger Ghaffarian Technologies, Inc., a major NASA contractor, to KBR in 2018. Together, they targeted the emerging commercial spaceflight market with the vision of building a privately funded space infrastructure.

In its early stages, Axiom Space focused on securing key partnerships and contracts. The company was selected by NASA to provide the first commercial destination module on the ISS, a significant milestone in its journey toward establishing a commercial space station.

NASA Contracts and Commercial Spaceflight

In 2020, Axiom Space was awarded a $140 million contract by NASA to provide at least one habitable spacecraft to attach to the ISS as part of the Next Space Technologies for Exploration Partnerships (NextSTEP) initiative. This contract underscored NASA’s confidence in Axiom’s capabilities and vision. Axiom’s modules are designed to attach to the Harmony forward port on the ISS, with plans to include a node module, a research and manufacturing facility, a crew habitat, and a “large-windowed” module for Earth viewing.

The company’s first commercial astronauts flew to the ISS in 2022 on Axiom Mission 1, marking a significant milestone in commercial spaceflight. This mission was operated by Axiom’s Mission Control Center in Houston and utilized SpaceX’s Falcon 9 rocket and Crew Dragon spacecraft. The mission demonstrated Axiom’s ability to plan, manage, and execute crewed spaceflights.

Axiom Station

Axiom Space’s ultimate goal is to build and operate the world’s first commercial space station, known as Axiom Station. The company plans to launch its modules individually and assemble them in orbit, initially attaching them to the ISS. Before the ISS is retired and reenters Earth’s atmosphere, Axiom plans to detach its modules and operate independently as Axiom Station.

Design and Features

The interior of Axiom Station, designed by French architect Philippe Starck, features walls covered with tufted padding and studded with hundreds of color-changing LEDs, creating a futuristic and comfortable environment. The station will include amenities such as high-speed Wi-Fi, video screens, picture windows, and a glass-walled cupola for stunning views of Earth.

By
JWST's Discovery of Ancient Galaxy Shakes Up Cosmic Theories: JADES-GS-z14-0

JWST’s Discovery of Ancient Galaxy Shakes Up Cosmic Theories: JADES-GS-z14-0

  • The James Webb Space Telescope (JWST) has detected the earliest galaxy ever observed, named JADES-GS-z14-0.
  • This galaxy formed around 300 million years after the Big Bang, challenging existing models of galaxy formation.
  • JADES-GS-z14-0 contains a massive halo of stars and significant amounts of dust and heavy elements.
  • Current theories suggest that galaxies in the early universe should have been smaller and less developed.
  • The discovery implies that galaxies could form and evolve much more quickly than previously thought.

Summary

  • Discovery of JADES-GS-z14-0: The James Webb Space Telescope’s detection of the galaxy JADES-GS-z14-0.
  • Formation Time: This galaxy formed roughly 300 million years post-Big Bang, presenting a mystery to scientists.
  • Star Formation: JADES-GS-z14-0 features a halo of freshly minted stars that have been forming for 90 million years.
  • Galactic Models Challenged: The galaxy’s characteristics defy current models that suggest galaxies grow gradually.
  • Researcher Insights: Scientists emphasize the need for updated galaxy formation models to explain these observations.
  • Elemental Composition: The galaxy contains high levels of dust and heavy elements, indicating rapid star formation.
  • Previous JWST Findings: Earlier JWST discoveries also revealed mature galaxies that challenge theoretical predictions.
  • Possible Explanations: Researchers are exploring various hypotheses including supermassive black holes and dark energy.
  • Future Research: Ongoing studies aim to uncover the mechanisms behind these early galactic formations.

 

The Introduction of JADES-GS-z14-0

The James Webb Space Telescope (JWST) has once again revolutionized our understanding of the universe with its latest discovery: the galaxy JADES-GS-z14-0. Detected by Webb’s Near InfraRed Spectrograph (NIRSpec) earlier this year, this galaxy is the earliest ever observed, forming around 300 million years after the Big Bang, which occurred approximately 13.8 billion years ago .

What astonished scientists most about JADES-GS-z14-0 is its early and rapid formation. The galaxy is surrounded by a massive halo of freshly minted stars that have been forming for at least 90 million years before the point of observation. This rapid star formation, just a couple hundred million years after the universe’s inception, defies current galaxy formation models .

The Challenge to Existing Models

Current theories suggest that galaxies in the early cosmos were supposed to start small and grow gradually over billions of years through processes like galactic mergers and the accretion of gas and dark matter. However, JADES-GS-z14-0 is far too massive and active for its age, challenging these traditional models.

Table 1: Comparison of Galactic Formation Models

Aspect of Formation Traditional Models JADES-GS-z14-0 Observations
Initial Growth Slow and gradual Rapid and massive
Star Formation Rate Low in early stages High, sustained over 90 million years
Elemental Composition Limited heavy elements Rich in dust and heavy elements
Galactic Mergers Essential for growth Unclear influence
Influence of Black Holes Not early in formation Possible early influence

Enriched Composition

Adding to the mystery, JADES-GS-z14-0 contains significant amounts of dust and heavy elements like oxygen. This suggests that the galaxy had already undergone multiple generations of star formation, enriching its interstellar medium with these elements long before its observed age of 290 million years .

This is not the first time the JWST has uncovered galaxies that challenge our understanding of the early universe. In 2023, the telescope revealed half a dozen massive galaxies that formed 500 to 700 million years after the Big Bang, defying 99 percent of theoretical predictions. These discoveries indicate that our current models of the early universe have serious blind spots .

JWST's Discovery of Ancient Galaxy Shakes Up Cosmic Theories: JADES-GS-z14-0

Table 2: Notable Early Galaxy Discoveries by JWST

Galaxy Name Formation Time After Big Bang Unique Characteristics
JADES-GS-z14-0 300 million years Rapid star formation, high dust content
HD1 330 million years Extremely luminous, massive starburst activity
GLASS-z13 400 million years High redshift, indicating early formation
CEERS-93316 500 million years High stellar mass, mature star population
Maisie’s Galaxy 700 million years Compact but highly luminous

Scientific Reactions

“The discovery by JWST of an abundance of luminous galaxies in the very early Universe suggests that galaxies developed rapidly, in apparent tension with many standard models,” the researchers wrote in a study published on July 29 in Nature . “Galaxy formation models will need to address the existence of such large and luminous galaxies so early in cosmic history.”

Scientists are exploring several hypotheses to explain these early, rapid galactic growth spurts. Some potential explanations include:

  • Earlier Formation of Supermassive Black Holes: These black holes might have existed earlier than previously thought, influencing galaxy formation.
  • Frequent Supernovae: The feedback effects from supernovae could have driven rapid star formation and growth.
  • Dark Energy Influence: Dark energy might play a role in accelerating the growth of early galaxies .

These discoveries imply that the universe is playing by a set of rules we have yet to fully understand. Our current models might need significant revisions to accommodate these new observations.

The Future of Cosmic Exploration

The JWST’s Advanced Deep Extragalactic Survey aims to explore these mysteries further. It observes more distant and ancient galaxies. By doing this, astronomers hope to understand the early history of the universe better. They also want to improve our models of galaxy formation.

Upcoming Research and Missions

Future missions and studies will focus on understanding the mechanisms behind these early galactic formations. Key areas of research include:

  • Supermassive Black Hole Formation: Investigating how and when these black holes form and their impact on galaxy evolution.
  • Star Formation Rates: Understanding the conditions that lead to rapid star formation in the early universe.
  • Cosmic Reionization: Studying how early galaxies contributed to the reionization of the universe .

Advancements in telescope technology and data analysis will play a crucial role in these investigations. Enhanced resolution, wider spectral coverage, and improved computational models will enable more detailed observations and insights .

Conclusion

The discovery of JADES-GS-z14-0 by the James Webb Space Telescope has profoundly impacted our understanding of the early universe. This ancient galaxy’s rapid formation and rich elemental composition challenge existing models and suggest that galaxies could evolve much more quickly than previously thought. As researchers continue to study these early cosmic phenomena, they will likely uncover new insights that reshape our understanding of the universe’s infancy .

The asteroid Dimorphos, a small moonlet orbiting the larger asteroid Didymos, has captured the attention of scientists worldwide. Following NASA’s Double Asteroid Redirection Test (DART) mission in September 2022, researchers have explored into the geology and formation of these celestial bodies. Surprisingly, they found that Dimorphos has a much fresher surface compared to Didymos.

The Age of Dimorphos and Didymos

One of the most striking discoveries about Dimorphos is its surface age. While Didymos has a surface age of approximately 12.5 million years, Dimorphos’ surface is estimated to be only 300,000 years old. This significant age difference suggests that Dimorphos’ surface has been resurfaced relatively recently in geological terms. The younger surface of Dimorphos has led scientists to investigate the processes that could contribute to this rapid resurfacing.

Rubble Pile Composition

Both Didymos and Dimorphos are classified as rubble pile asteroids. This means they are not solid bodies but rather loose aggregates of rocks, boulders, gravel, and dust held together by their own gravity. Andy Rivkin, DART investigation team co-lead at the Johns Hopkins Applied Physics Lab (APL), described Dimorphos as “a pile of gravel and boulders (and some sand/dust) held together by its own gravity, and really not anything else.” This lack of cohesion between the different pieces makes rubble pile asteroids particularly interesting and challenging to study.

Impact of the DART Mission

The DART mission aimed to test the kinetic impactor technique as a method for planetary defense. By intentionally crashing into Dimorphos, the mission successfully altered the moonlet’s orbit, decreasing its orbital period by about 34 minutes. The significant change in Dimorphos’ orbit can be attributed to its rubble pile composition. A collection of loosely bound boulders is easier to shift than a solid object, highlighting the potential effectiveness of kinetic impactors in diverting hazardous asteroids.

Geology and Surface Characteristics

The images and data collected by DART provided a close-up view of the Didymos/Dimorphos system. Olivier Barnouin, Ronald-Louis Ballouz, and their team at APL used this information to determine the surface characteristics and ages of both asteroids. They found that the weak surface characteristics of these bodies contributed to the effectiveness of the DART impact. Dimorphos, covered with boulders of varying sizes, contrasts with the smoother, though still rocky, surface of Didymos at lower elevations.

Formation of Dimorphos

Researchers believe that Dimorphos likely formed from material shed by Didymos. The spin-up of Didymos, leading to a large mass shedding event, could have resulted in the formation of Dimorphos. This process was confirmed in a study by Maurizio Pajola and his team from the National Institute for Astrophysics (INAF) in Rome. They concluded that both Didymos and Dimorphos are primarily composed of boulders formed through the catastrophic disruption of their progenitors.

Thermal Fatigue and Boulder Fracturing

One of the critical processes affecting Dimorphos’ surface is thermal fatigue. Alice Lucchetti and colleagues from INAF discovered that the size and distribution of boulders on Dimorphos are consistent with thermal fatigue. This phenomenon involves the gradual weakening and cracking of materials due to heat, causing boulders to break up more rapidly than previously thought. Thermal fatigue significantly alters the physical characteristics of asteroids, contributing to their rapid resurfacing.

“The presence of boulder fields affected by thermal fracturing on near-Earth asteroid surfaces may contribute to an enhancement in the ejected mass and momentum from kinetic impactors when deflecting asteroids,” noted the authors of the study.

Bearing Capacity of Didymos

Understanding the surface’s ability to support applied loads, or bearing capacity, is crucial for predicting how an asteroid’s surface will respond to impacts. Jeanne Bigot and Pauline Lombardo from ISAE-SUPAERO in Toulouse, France, led a study that estimated Didymos’ bearing capacity. They found it to be only 0.1% that of dry sand on Earth. This low bearing capacity is an essential parameter for planetary defense strategies and future missions targeting asteroid displacement.

Comparative Analysis of Rubble Pile Asteroids

Colas Robin and co-authors conducted a comparative analysis of surface boulders on Dimorphos and other rubble pile asteroids, such as Itokawa, Ryugu, and Bennu. They found striking similarities in the boulders across these asteroids, suggesting they formed and evolved in a similar fashion. The data gathered from these comparisons provide valuable insights for future planetary defense missions and the interpretation of impactor missions.

Future Missions and Studies

The DART mission has paved the way for further research and exploration of the Didymos/Dimorphos system. ESA’s Hera mission, set to launch in 2024, will arrive at Didymos and Dimorphos in December 2026. Hera will conduct a detailed study of Dimorphos, examining the long-term effects of the DART impact and providing more insights into the moonlet’s geology and evolution.

Conclusion

Dimorphos’ surprisingly fresh surface and its rubble pile composition have provided scientists with valuable information about the formation and evolution of asteroids. The DART mission’s successful alteration of Dimorphos’ orbit demonstrates the potential of kinetic impactors for planetary defense. As researchers continue to study the Didymos/Dimorphos system, our understanding of these celestial bodies and their role in the history of our Solar System will continue to grow. The findings from the DART mission and future missions like Hera will inform strategies for protecting Earth from potential asteroid threats.
