Hera Mission – Europe Launches to Investigate Asteroid Hit by NASA

In an age where space exploration is more focused on planetary defense, humanity has taken a significant step toward safeguarding Earth. On October 7, 2024, the European Space Agency (ESA) launched the Hera mission, marking the next phase in the study of asteroids. Hera will investigate the binary asteroid system Didymos and its smaller moon Dimorphos, which NASA’s DART mission impacted in 2022. The goal is to collect critical data on planetary defense strategies that may one day protect Earth from rogue space rocks.

NASA’s DART (Double Asteroid Redirect Mission) struck Dimorphos to test if an asteroid’s orbit could be altered. The mission succeeded, reducing Dimorphos’ orbit around Didymos by 33 minutes. Now, Hera will build on DART’s success by conducting a more detailed study of the asteroid’s changes, surface characteristics, and impact crater.

Mission Overview

The Hera mission was launched aboard a SpaceX Falcon 9 rocket from Cape Canaveral at 10:52 a.m. EDT. Unlike most SpaceX launches, the first stage of the Falcon 9 did not return to Earth for reuse. To ensure Hera had enough fuel to reach its target, the booster burned up its reserves entirely, leading to a planned disposal in the ocean. This particular Falcon 9 booster had been used in 23 previous missions, including Starlink satellite launches, NASA astronaut flights, and rideshare missions.

Hera’s journey will take it through the solar system, passing by Mars in 2025 for a gravity assist before heading to its final destination – the binary asteroid system of Didymos and Dimorphos.

Why Dimorphos?

The choice of Dimorphos as the mission’s target is strategic. The DART impact on the asteroid in 2022 was the first attempt by humanity to intentionally change the orbit of a celestial body. DART’s success demonstrated the potential of using kinetic impactors to deflect an asteroid’s path, offering hope that we could one day protect Earth from a catastrophic collision.

“We are now going back to Didymos and Dimorphos, we’ll make those measurements, and we’ll make the world a safer place from the impact of asteroids.”
– Alan Fitzsimmons, Hera Science Team Board Member

Hera will examine whether the DART impact did more than alter Dimorphos’ orbit. It will investigate whether the impact changed Dimorphos’ surface composition or even its shape. Additionally, the mission will measure the size and depth of the crater left by DART’s collision, further refining models for future asteroid deflection strategies.

International Planetary Defense

One of the most exciting aspects of Hera is its contribution to the growing field of planetary defense. Earth is constantly under the threat of potential impacts from asteroids, and understanding how to deflect or destroy these bodies is vital to our survival. Hera is part of a larger, international effort to protect our planet. As ESA Director General Josef Aschbacher put it:

“Defending our planet from space threats involves countries from all around the world. I am very pleased about this cooperation. The Hera spacecraft is a project by ESA, which stands for the European Space Agency. This spacecraft is leading Europe’s efforts to protect Earth from potential dangers from space.”

While the NASA DART mission proved that an asteroid could be deflected, Hera will refine our understanding of how such impacts work and how effective they can be.

What Will Hera Do?

Once Hera arrives at Dimorphos in 2026, it will begin its mission of measuring the impact crater created by DART. Scientists are eager to learn how much material was ejected during the collision and how deep the crater penetrated into the asteroid’s surface.

Mission Objectives

  1. Crater Measurement: Hera will assess the depth and diameter of the crater caused by DART.
  2. Orbital Analysis: Confirm the orbital changes caused by DART’s impact.
  3. Surface Examination: Analyze the composition of surface minerals and look for any shape alterations in Dimorphos.
  4. Cubesat Exploration: Hera carries two smaller satellites, Milani and Juventas, which will examine Dimorphos’ gravity, structure, and surface features.
  5. Refining Models: The data from Hera will help scientists refine their models for asteroid deflection techniques, improving future missions.

The Cubesats: Milani and Juventas

A significant part of Hera’s mission involves two smaller spacecraft: Milani and Juventas. These cubesats will deploy once Hera reaches Dimorphos and begin their own investigations. Milani will focus on the surface composition, examining minerals and the asteroid’s structure. Juventas, on the other hand, will use a radar instrument to explore the internal structure of Dimorphos. This will provide insights into how asteroids are formed and how they behave when struck by external forces like DART.

Technical Aspects of the Mission

Main Article

The Federal Aviation Administration (FAA) has grounded SpaceX’s Falcon rocket fleet for the third time in three months following a second-stage malfunction. This latest incident occurred during a high-profile mission that successfully transported two astronauts to the International Space Station (ISS) aboard a Dragon Crew capsule on Saturday. While the capsule reached its destination without issue, the rocket’s second stage suffered a failure less than 30 minutes after the astronauts were delivered into orbit.

This malfunction caused the FAA to halt additional SpaceX launches, including two major missions: the launch of OneWeb satellites and a Starlink satellite mission. The disruption could also impact critical upcoming solar system exploration missions from NASA and the European Space Agency (ESA), both of which have narrow launch windows scheduled for later this month.

The Second-Stage Failure

The Falcon 9’s Merlin Vacuum engine, designed to boost the rocket’s second stage into a higher orbit, failed to fire correctly. The second stage was tasked with executing a deorbit burn, a maneuver intended to guide the rocket safely back to Earth by burning up in the atmosphere. Without the proper deorbit burn, debris from the rocket could potentially fall outside of the designated area, leading to space debris concerns.

In a statement, SpaceX acknowledged the issue, stating:

Falcon 9’s second stage was disposed in the ocean as planned, but experienced an off-nominal deorbit burn. As a result, the second stage safely landed in the ocean, but outside of the targeted area.”

SpaceX has since been working on identifying the root cause of the malfunction. Although the issue was not catastrophic, the FAA requires a full investigation before launches can resume.

FAA Grounds SpaceX Falcon Rocket Again After Second-Stage Malfunction

The failure of the deorbit burn raised concerns over space debris, often referred to as orbital space junk. Debris from failed rocket stages can pose significant risks to other spacecraft, satellites, and space stations in low Earth orbit. The FAA’s grounding of the Falcon rockets highlights the growing concern over maintaining safety in an increasingly crowded space environment.

This is not the first time SpaceX has faced issues with its rockets. Earlier this year, a Falcon 9 rocket suffered a second-stage explosion that sent several Starlink satellites on a destructive trajectory. Additionally, a Falcon 9 first stage made a crash landing on a drone ship after a different mission.

Impact on NASA and ESA Missions

The Hera mission, developed by the ESA to explore the Didymos binary asteroid system, and NASA’s Europa Clipper mission, which aims to study Jupiter’s moon Europa, are both at risk of delays. These missions have specific launch windows that must be adhered to in order to reach their destinations efficiently. Any delays could push back these high-priority exploration missions, costing both agencies valuable time and resources.

Mission Agency Launch Window Destination
Hera Mission ESA October 7-27 Didymos Binary Asteroid System
Europa Clipper NASA October 10-30 Jupiter’s Moon Europa

The potential delay of these missions is particularly concerning for NASA’s Europa Clipper, a $5 billion project that seeks to unlock the mysteries of one of the solar system’s most intriguing moons. The Falcon Heavy rocket, which shares its second-stage design with Falcon 9, is slated to carry this mission.

SpaceX’s Response and Investigation

SpaceX has a track record of quick response times and thorough investigations following any malfunctions. In July, a previous second-stage failure led to a 15-day suspension of Falcon 9 flights. The company determined that the issue was a liquid oxygen leak, which was quickly resolved with modifications to the rocket’s design. Similarly, SpaceX is expected to rapidly identify and fix the current malfunction.

Despite these setbacks, Falcon 9 remains one of the most reliable rockets in the world, with a success rate of over 98% across more than 200 launches. However, the FAA’s involvement complicates the situation. SpaceX is currently embroiled in a legal dispute with the agency over delays in authorizing the fifth test flight of its Starship rocket at its South Texas facility. This dispute, combined with the current suspension, could result in further delays for SpaceX’s ambitious space exploration goals.

FAA Grounds SpaceX Falcon Rocket Again After Second-Stage Malfunction

Rocket Mission Success Rate Notable Issues
Falcon 9 98% Second-stage failures, first-stage landing mishaps
Falcon Heavy 100% None

SpaceX’s Falcon Heavy is still scheduled to launch NASA’s Europa Clipper mission later this month, assuming the investigation wraps up in time. The company’s ability to learn from its mistakes and implement solutions swiftly will likely prevent further interruptions in its busy launch schedule.

The mission is led by Jared Isaacman, a US billionaire who previously chartered the Inspiration4 mission, the first all-civilian orbital spaceflight in 2021. The Polaris Dawn mission represents not just a technical achievement but also a major step forward in the commercialization of space.

The Polaris Dawn Mission

The Polaris Dawn mission is a five-day expedition that will take place aboard a SpaceX Falcon 9 rocket. The launch is scheduled to take place before dawn next Monday from the Kennedy Space Center in Florida. The mission will carry a crew of four, including Jared Isaacman, SpaceX employees Sarah Gillis and Anna Menon, and pilot Scott Poteet.

Jared Isaacman, who is funding the mission jointly with SpaceX, spoke about the journey so far during a press conference on Monday. “It’s been two and a half years since we announced the Polaris program. It’s been a really exciting journey of development and training,” Isaacman said. He did not disclose the amount he has spent on the Polaris program, which includes a total of three missions.

Advanced Space Suits for the Mission

One of the highlights of the Polaris Dawn mission is the new generation of space suits developed by SpaceX. These suits are white and futuristic in design, marking a departure from the traditional bulky space suits of the past. The suits are designed to withstand the extreme conditions of space, including intense radiation and extreme temperatures.

Elon Musk, CEO of SpaceX, expressed his excitement about the mission on X (formerly Twitter), stating, “This will be epic.

The space suits are not just a design improvement but also a technological advancement. They include built-in cameras that will capture every moment of the spacewalk, providing a unique perspective to viewers back on Earth. Jared Isaacman shared his thoughts on the new suits: “Someday, someone could be wearing a version of the suit as they are walking on Mars. It feels like a huge honor to have that opportunity to test it out on this flight.”

The Crew Members

The crew of the Polaris Dawn mission is a mix of experienced professionals who bring a wealth of knowledge and skills to the mission.

  • Jared Isaacman: Mission commander and leader of the mission, Isaacman is a billionaire entrepreneur and space enthusiast. He previously led the Inspiration4 mission.
  • Sarah Gillis: A SpaceX employee responsible for astronaut training, Gillis played a key role in training Isaacman for the Inspiration4 mission. This mission will be her first time in space.
  • Anna Menon: Another SpaceX employee, Menon has a background in aerospace engineering and previously worked for NASA. She expressed her excitement about the mission, saying, “I’ve spent years trying to put myself in the seat of astronauts in space, and I am really looking forward to learning firsthand what that experience is actually like.”
  • Scott Poteet: A close friend of Isaacman, Poteet is a seasoned pilot with 20 years of experience flying fighter jets in the US Air Force. He has undergone rigorous training to prepare for this mission. Poteet described the training as “some of the most challenging training that I’ve ever experienced.”

The crew has undergone extensive and challenging training to prepare for the Polaris Dawn mission. Their training included over 2,000 hours in a simulator, centrifuge sessions, scuba diving, skydiving, and even climbing the Cotopaxi volcano in Ecuador. The goal of this intense training was to prepare the crew for the physical and mental challenges they will face during the mission.

Scott Poteet described the training as incredibly demanding, stating, “I can tell you without a doubt, this has been some of the most challenging training that I’ve ever experienced.”

Mission Objectives

The Polaris Dawn mission has three main objectives:

  1. Reaching Record Altitudes: The mission aims to reach an altitude of 1,400 kilometers (870 miles), the furthest distance for a space crew since the Apollo lunar missions. This will be a record-breaking achievement, especially for Sarah Gillis and Anna Menon, who will become the two women to have traveled the farthest from Earth.
  2. Laser Communication Test: The second objective is to conduct a laser communication test between the spacecraft and SpaceX’s Starlink satellites. This test will demonstrate the ability to communicate effectively using lasers, which could be crucial for future space missions, especially those that travel beyond Earth’s orbit.
  3. First Commercial Spacewalk: The highlight of the mission is the first-ever commercial spacewalk, which will be broadcast live on the mission’s third day. The spacewalk will involve two astronauts venturing outside the Dragon capsule, while the other two remain inside. The spacewalk will be conducted in a lower orbit, and the crew will test the new space suits’ capabilities. Jared Isaacman described the spacewalk as a “hands-free demonstration,” where the astronauts will perform movements to test the suit’s performance.

Challenges of the Spacewalk

The spacewalk presents unique challenges for the crew. Since the Dragon capsule has no airlock, the entire spacecraft will be exposed to the vacuum of space when the hatch is opened. This means that the astronauts must carefully coordinate their movements to avoid any mishaps.

Jared Isaacman and his team have spent considerable time training for the spacewalk, and they are confident in their ability to carry out the mission successfully. The new space suits are designed to protect the astronauts from the harsh conditions of space, but the mission will be a critical test of their effectiveness.

The Role of Private Sector in Space Exploration

The Polaris Dawn mission highlights the growing role of the private sector in space exploration. Companies like SpaceX are playing an increasingly important role in advancing human space exploration, and the mission is a testament to the progress that can be made when private companies are involved. Jared Isaacman praised the private sector’s contributions, stating, “I’d certainly like my kids to see humans walking on the Moon and Mars and venturing out and exploring our solar system. We haven’t even scratched the surface yet. There’s so much to go out and explore and discover along the way.”

Future Missions

The Polaris program includes a total of three missions, with the Polaris Dawn mission being the first. The second mission is expected to be similar, but with more advanced objectives. The third mission, however, will be the most ambitious of them all. It will involve the first crewed flight on SpaceX’s Starship rocket, which is currently under development. The Starship is intended for missions to the Moon, Mars, and beyond.

Conclusion

The Polaris Dawn mission is set to be a historic event in the world of space exploration. As SpaceX prepares for its first-ever private spacewalk, the mission represents a significant achievement for the company and the broader space industry. With new technologies, rigorous training, and a dedicated crew, the mission is poised to make history and pave the way for future private space exploration. As Jared Isaacman said, “We haven’t even scratched the surface yet. There’s so much to go out and explore and discover along the way.”

  • Starship Tests: SpaceX is preparing for the fifth test flight of its Starship/Super Heavy system.
  • FAA Oversight: The FAA will continue to monitor SpaceX’s activities to ensure safety.

Introduction

SpaceX, the aerospace company founded by Elon Musk, has made headlines once again with the resumption of its Falcon 9 rocket launches. After a failed mission on July 11, which led to a temporary halt in operations, the company received a crucial green light from the Federal Aviation Administration (FAA) on July 25. This approval was a significant step in getting SpaceX back on track with its ambitious space exploration plans.

The July 11 Failure

On July 11, 2024, a Falcon 9 rocket experienced a significant failure that halted SpaceX’s flight schedule. The issue was traced to a crack in a pressure sensor line for the upper stage’s liquid-oxygen system. This crack caused an oxygen leak, which in turn led to degraded performance of the upper-stage engine. The failure resulted in the loss of 20 Starlink satellites that were intended to enhance SpaceX’s high-speed internet network.

The problem was identified as a fatigue crack in the sense line, which is crucial for monitoring the pressure of the liquid-oxygen system. According to SpaceX, the crack was caused by high loading from engine vibrations and a looseness in the clamp that normally holds the line in place. This malfunction led to excessive cooling of engine components during a planned coast phase, resulting in a hard start upon engine restart and damage to the hardware.

SpaceX took immediate action to address the issue. The company worked under FAA oversight to pinpoint the root cause and develop a corrective strategy. They removed the faulty sense lines and sensors from the upper stages of upcoming Falcon 9 rockets. As a result, the company could clear the way for the resumption of flights.

“The sensor is not used by the flight safety system and can be covered by alternate sensors already present on the engine,” SpaceX explained in a statement.

Resumption of Launches

Following the FAA’s green light, SpaceX quickly got back to its flight schedule. On July 26, 2024, the company successfully launched a Falcon 9 rocket from NASA’s Kennedy Space Center in Florida. The launch was notable for several reasons:

  • Timing: The rocket lifted off at 1:45 a.m. ET (05:45 GMT), demonstrating SpaceX’s ability to resume operations with minimal delay.
  • Mission Objective: Like the failed July 11 mission, this launch also carried a batch of SpaceX’s Starlink satellites to low Earth orbit.
  • Launch Success: The launch appeared to proceed without incident. The first-stage booster successfully landed on a drone ship in the Atlantic Ocean, while the second stage deployed 23 Starlink satellites into orbit.

The FAA’s evaluation of the July 11 failure concluded that there were no public safety issues involved. The agency’s determination allowed Falcon 9 rockets to return to flight operations while the overall investigation into the anomaly remained open. This decision reflects the FAA’s confidence in SpaceX’s ability to manage safety and address issues promptly.

Upcoming Missions and Future Prospects

SpaceX has several high-profile missions lined up, which include both crewed and uncrewed flights. These missions are critical for the company’s continued success and its role in advancing space exploration.

Polaris Dawn Mission

One of the upcoming missions is the Polaris Dawn mission, which is privately funded and led by billionaire entrepreneur Jared Isaacman. Scheduled for late summer, the Polaris Dawn mission will feature the first private-sector spacewalk.
