The Full Article

Space travel is one of humanity’s most remarkable achievements, but it comes with incredible risks. For astronauts like Sunita Williams, these risks become reality, especially when a mission doesn’t go as planned. As Williams has been stranded at the International Space Station (ISS) for over five months, the consequences of prolonged exposure to microgravity and isolation have become evident.

What Happened?

Sunita Williams, of Indian origin, and her colleague Butch Wilmore were initially scheduled to stay at the ISS for just eight days. However, a malfunction in Boeing’s Starliner spacecraft changed everything. The Starliner, initially intended to ferry them back to Earth, was deemed too hazardous for human travel after a critical malfunction. The two astronauts have now been on the ISS for more than 150 days.

“She has lost a lot of weight,” a NASA employee said in an interview with the New York Post. “The pounds have melted off her and she’s now skin and bones.” The health concerns have grown more serious with time, and Williams’ thin and frail appearance has worried experts and the general public.

How Space Affects the Human Body

Spending long durations in a microgravity environment impacts nearly every bodily system. Here’s a look at the physiological effects:

Weight Loss and Metabolism Astronauts must consume between 3,500 and 5,000 calories daily just to maintain their weight. This is because the microgravity environment increases their metabolism. If they fall behind, as has happened with Williams, rapid and dangerous weight loss can occur.
Muscle and Bone Loss In microgravity, bones lose minerals, leading to density loss at a rate of about 1% per month. Muscles, including the heart, weaken significantly due to a lack of regular resistance.
Heart and Vision Issues Space travel causes the heart to shrink slightly, and fluids shift in the body, often putting pressure on the eyes and affecting vision. Extended missions exacerbate these problems, creating long-term health implications.
Radiation Exposure Astronauts are exposed to higher levels of cosmic radiation, increasing the risk of cancer, cataracts, and neurological disorders. Sunita Williams and her colleague will continue to face these risks until their return.

Sunita Williams' Health Concerns in Space NASA's Official Response — NASA astronaut Suni Williams is the Commander of Expedition 72. She wears a pirate’s eye patch to celebrate Halloween. She is orbiting Earth on the International Space Station. The International Space Station, also known as the ISS, is a large spacecraft. It orbits Earth at a high altitude. People live and work there. NASA took a picture of Suni Williams.

Table 1: Health Effects of Long-Term Space Travel

Effect	Details
Weight Loss	Rapid due to high metabolic demands
Muscle Deterioration	Loss of muscle mass and strength
Bone Density Loss	1% loss per month in microgravity
Vision Impairments	Fluid shifts cause pressure on the eyes
Radiation Exposure	Increased risk of cancer and cataracts

Diet and Nutrition in Space

Astronauts have to eat twice as many calories as people on Earth. This requires a balanced diet of carbohydrates, fats, proteins, vitamins, and minerals. The space diet includes:

Freeze-Dried Foods: These foods have water removed through freezing and vacuum drying. To consume them, astronauts inject water into the packages.
Thermo-Stabilized Foods: Items like fish and chicken are heat-processed to kill bacteria.
Snacks: Nuts, granola bars, and cookies are sealed in clear pouches to preserve freshness.
Powdered Beverages: Hydration is crucial, and drinks are provided in powdered form, mixed with water.

Astronauts must consume meals three times a day, alongside snacks, to maintain energy and muscle mass. Special consideration is given to bone density, so diets are rich in calcium and vitamin D.

The Gender Factor in Space Travel

Research has shown that space travel affects men and women differently. A 2023 NASA study indicated that women lose muscle mass at a faster rate than men. This puts female astronauts at a disadvantage, requiring tailored exercise and dietary interventions.

“Space has a unique way of revealing human limitations and forcing us to adapt,” a NASA researcher explained. “We’ve learned that gender can significantly influence how the body responds to space, and we need to continue our research to ensure equality and safety.”

This revelation has led to new discussions about making space travel more inclusive and safer for everyone. For Sunita Williams, the unique challenges posed by her prolonged stay underscore the need for these ongoing studies.

NASA’s Official Response

NASA has been quick to reassure the public. Jimi Russell, spokesperson for NASA’s Space Operations Mission Directorate, told the Daily Mail, “All astronauts currently stationed on the ISS are in good health and undergoing routine medical evaluations.” However, the images of Williams’ weight loss have caused widespread concern.

To address this, NASA’s medical team has been actively working with Williams. The agency has increased her caloric intake and devised strategies to help her regain weight. Despite these efforts, the limited food variety and harsh conditions of space make recovery challenging.

Exercise Regimens on the ISS

Exercise is a crucial component of life in space. Astronauts spend two hours daily exercising to maintain muscle and bone health. The ISS is equipped with:

Treadmills: Special harnesses keep astronauts tethered while running.
Stationary Bicycles: Astronauts pedal in a microgravity environment to strengthen their legs.
Resistance Machines: These mimic weightlifting, using vacuum cylinders instead of gravity.

Table 2: Exercise Equipment on the ISS

Equipment	Purpose
Treadmill	Cardiovascular health and leg muscle maintenance
Stationary Bicycle	Cardiovascular exercise
Resistance Machines	Muscle strength using vacuum resistance

Long-Term Plans: Awaiting SpaceX Crew-9

Sunita Williams and Butch Wilmore are scheduled to return aboard SpaceX’s Crew-9 Dragon capsule, but the mission won’t arrive until February 2025. Until then, the astronauts must endure the challenges of microgravity, limited resources, and the psychological strain of isolation.

NASA has emphasized the importance of monitoring both physical and mental health. The crew receives regular support from ground-based psychologists and has access to communication channels to stay connected with their loved ones.

Boeing’s Starliner issue has exposed the vulnerabilities of human space exploration. The incident has triggered a broader conversation about the safety of spacecraft and the need for robust contingency plans. Delays and malfunctions can have serious consequences, as seen with the extended mission of Williams and Wilmore.

Facts About Astronaut Life

Space Sleep: Astronauts sleep in sleeping bags attached to walls to prevent floating away.
Cosmic Showers: They use special no-rinse shampoos to stay clean.
Space Suits: Each suit costs around $12 million.
Earth Views: Astronauts see 16 sunrises and sunsets every day on the ISS.
Space Music: Playing instruments like guitars is a popular pastime.

Main Article

On September 7, 2024, Boeing’s Starliner spacecraft made a triumphant return to Earth after more than three months in space. Initially planned as a 10-day Crew Flight Test (CFT) mission, the spacecraft experienced delays that extended the mission significantly. Despite the unexpected issues that arose, NASA affirmed that astronauts aboard the spacecraft would have been safe. The mission represents a crucial step in the development of Starliner as a crew transport vehicle to the International Space Station (ISS).

Steve Stich, the manager of NASA’s Commercial Crew Program, emphasized the confidence NASA has in Starliner’s performance, saying, “If we’d have had a crew on board the spacecraft, we would have followed the same back-away sequence from the space station, the same deorbit burn and executed the same entry. And so it would have been a safe, successful landing with the crew on board.”

NASA and Boeing’s Approach to Safety

Safety has always been the top priority for both NASA and Boeing. The three-month delay in Starliner’s return was prompted by issues with the spacecraft’s thrusters as it approached the ISS. These technical problems, while concerning, allowed NASA and Boeing to reevaluate and troubleshoot the spacecraft’s systems thoroughly. In the words of Stich, “It’s always hard to have that retrospective look. If we’d had a model that would have predicted what we saw tonight perfectly, yeah, it looks like an easy decision to go say we could have had a crewed flight, but we didn’t have that.”

NASA decided to return the spacecraft without any crew. They made this choice after studying the situation carefully. This helped them make sure that any dangers to astronauts were removed before sending humans on board.

The Crew Flight Test (CFT) mission was supposed to be Starliner’s final test before entering regular service as a crew transport vehicle to the ISS. NASA astronauts Butch Wilmore and Suni Williams were initially set to return with the spacecraft, but the thruster issues prompted NASA to revise its plan.

After launching aboard Starliner on June 4, 2024, Wilmore and Williams expected to spend about 10 days in space. However, NASA announced in late August that Starliner would return uncrewed. The decision resulted in the reassignment of Wilmore and Williams to ISS Expedition 71. They will now spend approximately ten months in space and return to Earth aboard SpaceX’s Crew Dragon in 2025.

This shift in plans, while unforeseen, has allowed NASA and Boeing to continue refining the spacecraft’s capabilities. Despite the setbacks, Starliner’s return to Earth went off without a hitch, landing at White Sands Missile Range in New Mexico at 12:01 a.m. EDT (0401 GMT) on September 7, 2024.

As Starliner approached the ISS for docking, engineers observed irregularities with the spacecraft’s orbital maneuvering and attitude control (OMAC) thrusters. These thrusters are crucial for the precise movements necessary to approach, dock, and undock from the ISS. The issue caused a significant delay, and NASA made the decision to delay the spacecraft’s return until they could fully understand and address the problem.

Over the next few months, extensive tests were conducted in White Sands, New Mexico, where NASA and Boeing engineers worked tirelessly to recreate the issues experienced in space. Ultimately, the spacecraft returned safely, with parachutes deploying as expected and landing softly in the New Mexico desert. This achievement demonstrated Starliner’s robustness despite the challenges encountered.

While Starliner completed its mission without its crew, astronauts Wilmore and Williams continue their extended stay aboard the ISS. The two astronauts will now return to Earth aboard a Crew Dragon spacecraft in February 2025. Instead of the planned 10 days in space, they will have spent ten months in orbit.

Despite the delays and challenges, Starliner’s safe return is an important milestone for NASA’s Commercial Crew Program. The program, which seeks to develop spacecraft that can safely transport astronauts to and from the ISS, now boasts two key players: SpaceX’s Crew Dragon and Boeing’s Starliner.

While SpaceX has already completed multiple successful crewed missions, Boeing’s Starliner has faced its fair share of delays. However, the safe landing of the spacecraft in New Mexico marks a significant step forward, bringing Starliner closer to operational status.

According to NASA Administrator Bill Nelson, “Starliner’s safe return is a testament to the dedication and perseverance of both NASA and Boeing teams. We are committed to ensuring the safety of our astronauts, and this mission brings us one step closer to making Starliner an integral part of our human spaceflight program.

With Starliner’s successful landing, both NASA and Boeing look to the future of human space exploration. The spacecraft, once fully operational, will play a critical role in ferrying astronauts to the ISS and potentially other destinations in low Earth orbit.

Boeing’s efforts to address and resolve the technical challenges faced during the CFT mission demonstrate the company’s resilience and determination. As Starliner continues to undergo rigorous testing and refinement, NASA remains confident that the spacecraft will soon be ready to transport astronauts regularly.

Starliner’s role in NASA’s future space missions goes beyond just ISS transport. The spacecraft’s design is adaptable, and Boeing has hinted at potential uses for missions to the Moon or Mars. With NASA’s Artemis program ramping up, Starliner could one day be a part of humanity’s return to the lunar surface.

The Role of NASA’s Commercial Crew Program

The Commercial Crew Program (CCP) has been a cornerstone of NASA’s efforts to foster collaboration with private companies in advancing human space exploration. By partnering with Boeing and SpaceX, NASA has sought to develop multiple spacecraft capable of transporting astronauts safely to and from space. This collaboration allows NASA to focus on deep space exploration, while companies like Boeing and SpaceX focus on low Earth orbit operations.

Table 1: NASA’s Commercial Crew Program Key Players

Company	Spacecraft	Status	Missions Completed

Introduction

On August 1, 2024, a routine space mission suddenly took a troubling turn. NASA astronauts Sunita Williams and Butch Wilmore heard strange, sonar-like sounds. These noises came from the Starliner capsule. This issue has added to growing concerns about Boeing’s spacecraft. The Starliner has faced many technical problems since it was first developed.

The report of the strange noises came from veteran NASA astronauts Sunita Williams and Butch Wilmore, both of whom have extensive experience in space missions. The astronauts, currently residing on the International Space Station (ISS), encountered what they described as a “pulsing noise, almost like a sonar ping,” coming from the Starliner capsule.

The recording of the noise, first shared by Michigan-based meteorologist Rob Dale, was later reported by Ars Technica. In the recording, Wilmore can be heard holding his phone up to the speakers so that NASA’s Mission Control could hear the sound. The pulsing noise was clear, coming out in regular beats, and was subsequently acknowledged by Mission Control.

“Butch, that one came through,” Mission Control responded. “It was kind of like a pulsating noise, almost like a sonar ping.”

Despite the clear recording, the source of the noise remains a mystery. Wilmore attempted to play the sound again to allow the team to identify what might be causing it. “I’ll do it one more time and let you all scratch your heads and see if you can figure out what’s going on,” Wilmore said.

NASA’s Mission Control has taken the report seriously, assuring the astronauts that the recording would be thoroughly investigated. “Good recording, thanks, Butch,” they replied. “We will pass it onto the team and let you know what we find.”

At the time of writing, there has been no official statement from NASA regarding the source of the noise. However, the incident has raised questions about the Starliner’s overall reliability, especially given the spacecraft’s troubled history.

The Boeing Starliner has been a point of contention since its development began. Originally conceived as part of NASA’s Commercial Crew Program, the Starliner was intended to provide a reliable and cost-effective means of transporting astronauts to and from the ISS. However, the project has been plagued by technical issues, delays, and budget overruns.

Table 1: Starliner Mission Timeline

Date	Event
2010	Boeing awarded contract to develop the Starliner
2019	Uncrewed test flight ends in failure
2021	Starliner’s first crewed flight delayed due to technical issues
2023	Successful launch, but with helium leaks and thruster failures
June 2024	Wilmore and Williams launch aboard Starliner
August 2024	Astronauts report strange sonar-like noises
September 2024	Unmanned Starliner return scheduled
February 2025	Wilmore and Williams expected to return via SpaceX capsule

One of the most significant challenges facing the Starliner has been its thruster system. During its first uncrewed test flight in 2019, the spacecraft encountered a software glitch that prevented it from reaching the ISS. Subsequent tests revealed issues with the thrusters, which were designed to help maneuver the spacecraft in space. In addition, the Starliner has suffered from helium leaks, further complicating its mission.

The date was June 13, 2024. | NASA via AP

In June 2024, when Wilmore and Williams launched toward the ISS aboard the Starliner, the spacecraft was already under intense scrutiny. The mission, originally planned as a one-week stay, was extended due to ongoing technical problems. By the time the astronauts arrived at the ISS, the Starliner had experienced more helium leaks and five of its 28 thrusters had failed.

The technical issues plaguing the Starliner have had a direct impact on the mission of Wilmore and Williams. What was intended to be a brief stay on the ISS has now stretched into several months, with the astronauts unable to return to Earth aboard the Starliner. Instead, they will remain on the ISS until February 2025, when a SpaceX capsule is scheduled to bring them home.

The decision to extend the astronauts’ stay and opt for a SpaceX return was not made lightly. In a press conference on August 24, NASA officials announced that it would be too risky to bring the astronauts back on the faulty Starliner. This decision underscores the severity of the technical issues and the potential risks involved in attempting to return the astronauts to Earth aboard the Starliner.

The ongoing issues with the Starliner have been a significant embarrassment for Boeing, which has invested over $4 billion of taxpayer money into the project. The repeated failures have cast doubt on the viability of the Starliner program and have led to growing dissatisfaction within the company.

“We have had so many embarrassments lately, we’re under a microscope. This just made it, like, 100 times worse,” one Boeing employee anonymously told the New York Post. “We hate SpaceX,” he added. “We talk s*** about them all the time, and now they’re bailing us out.”

With the ISS set to be decommissioned by 2030, Boeing has a limited window of time to resolve the ongoing technical issues and prove the Starliner’s reliability. The spacecraft has already experienced significant delays, and the current situation only adds to the uncertainty surrounding its future.

Boeing has already sunk $1.6 billion into the Starliner’s development, and questions are being raised about whether the company will continue to invest in the project. The financial and reputational stakes are high, and the pressure is mounting on Boeing to deliver a reliable spacecraft.

Possible Explanations for the Strange Noises

While the source of the strange sonar-like noises remains unknown, there are several possible explanations that have been suggested by experts. One possibility is that the noise is related to the spacecraft’s thruster system, which has already been identified as a point of concern. Another possibility is that the noise is being caused by a malfunction in one of the spacecraft’s systems, such as its communication equipment or life support systems.

Some experts have also suggested that the noise could be related to the spacecraft’s interaction with the surrounding environment in space. The vacuum of space presents unique challenges for spacecraft, and it is possible that the noise is being generated by some kind of interaction between the Starliner and its environment.

The Role of SpaceX in NASA’s Future Plans

The decision to bring Wilmore and Williams back to Earth aboard a SpaceX capsule highlights the growing role that SpaceX is playing in NASA’s future plans. The company, founded by Elon Musk, has become a key partner for NASA, providing reliable transportation to and from the ISS.

SpaceX’s Crew Dragon spacecraft has already proven its reliability, with multiple successful missions under its belt. The company’s success stands in stark contrast to Boeing’s struggles, and it is clear that NASA is increasingly relying on SpaceX to fulfill its space exploration goals.

The next major milestone for the Starliner program will be the spacecraft’s return to Earth in September 2024. The capsule will return unmanned, landing in New Mexico. The return will be closely watched, as it will provide valuable data on the spacecraft’s performance and offer insights into the technical challenges that need to be addressed.

For Boeing, the return of the Starliner represents a critical opportunity to demonstrate the spacecraft’s capabilities and address the concerns that have been raised. The company will need to carefully analyze the data from the return and work to resolve the issues that have plagued the program.

In a surprising yet prudent move, NASA has decided to remove two astronauts from its forthcoming SpaceX Crew-9 mission. This decision, made to accommodate two astronauts originally scheduled to return to Earth on Boeing’s Starliner, This shows how space missions can be very dynamic and sometimes unpredictable. The Crew-9 mission will now continue with only two astronauts. These astronauts are Nick Hague from NASA and Aleksandr Gorbunov from Roscosmos, which is the Russian space agency.

Boeing’s Starliner, which has been undergoing a historic first test mission with astronauts, encountered significant issues with its propulsion system and thrusters. These problems raised concerns about the spacecraft’s ability to safely return astronauts to Earth. After two months of rigorous tests and safety discussions, NASA concluded that the risk associated with the Starliner’s thrusters was too high to allow for a crewed return.

Instead, NASA decided to bring the Starliner back to Earth uncrewed, scheduled for September 6, 2024. This decision necessitated a reassignment of astronauts Butch Wilmore and Suni Williams, who were to return on the Starliner. The safest and most logical solution was to include them in the Crew-9 mission, thus prompting the removal of two original Crew-9 astronauts, Zena Cardman and Stephanie Wilson.

With the changes, Crew-9 will now be a half-empty flight with only two crew members: Nick Hague and Aleksandr Gorbunov. Hague, who was originally the pilot of the mission, has been promoted to commander, while Gorbunov will remain as the mission specialist.

Nick Hague, a U.S. Space Force commander and former test pilot, has had an illustrious career in space exploration. He has already been to space twice as a NASA astronaut, although his first trip was cut short due to a rocket malfunction during a Soyuz launch in 2018. Despite this setback, Hague and his cosmonaut colleague Alexey Ovchinin safely returned to Earth, and both successfully completed a full ISS mission on their second attempt in 2019.

Aleksandr Gorbunov, on the other hand, will be making his first spaceflight on the Crew-9 mission. His seat is part of a NASA arrangement with Roscosmos, ensuring the continued presence of Russian astronauts on NASA missions, and vice versa. This collaboration is crucial for maintaining international relations and ensuring the success of joint space endeavors.

The decision to reassign astronauts has led to a delay in the Crew-9 launch, which is now scheduled for September 24, 2024. However, this date remains tentative due to complications arising from a separate incident involving SpaceX’s Falcon 9 rocket. The Falcon 9, which was set to launch the Crew Dragon spacecraft for the Crew-9 mission, is currently grounded following the loss of a different Falcon 9 variant during a Starlink satellite mission on August 28, 2024.

The incident has triggered an investigation by the Federal Aviation Administration (FAA), NASA, and SpaceX, adding another layer of uncertainty to the Crew-9 mission timeline. The outcome of this investigation will be critical in determining whether the new launch date can be met or if further delays are necessary.

The Boeing Starliner program has faced numerous challenges since its inception. Despite its initial promise as a competitor to SpaceX’s Crew Dragon, the Starliner has been plagued by technical issues and delays. The propulsion system problems encountered during this test mission are just the latest in a series of setbacks that have raised questions about the spacecraft’s reliability and safety.

However, it is important to recognize the significance of the Starliner program in the broader context of space exploration. Boeing’s efforts to develop a reliable and safe spacecraft for crewed missions are part of a larger push to expand humanity’s presence in space. The Starliner represents a critical component of NASA’s Commercial Crew Program, which aims to reduce dependence on Russian spacecraft and provide the United States with its own means of sending astronauts to space.

Despite the challenges, NASA and Boeing remain committed to the success of the Starliner program. The upcoming uncrewed return of the Starliner will provide valuable data that will be used to address the propulsion issues and improve the spacecraft’s performance in future missions.

The collaboration between SpaceX and NASA has been a cornerstone of recent advancements in space exploration. SpaceX’s Crew Dragon spacecraft has proven to be a reliable and safe vehicle for transporting astronauts to and from the International Space Station (ISS). The success of the Crew Dragon missions has allowed NASA to focus on other critical areas of space exploration, including the Artemis program, which aims to return humans to the Moon by the mid-2020s.

The recent challenges with Boeing’s Starliner and the Falcon 9 incident highlight the inherent risks and complexities of space exploration. However, they also underscore the resilience and adaptability of NASA and its commercial partners. The decision to reassign astronauts from the Starliner to the Crew Dragon is a testament to NASA’s commitment to astronaut safety and mission success.

Looking ahead, the partnership between NASA and SpaceX is expected to continue playing a pivotal role in advancing human space exploration. As NASA works to overcome the challenges with the Starliner and Falcon 9, the agency remains focused on its long-term goals, including the establishment of a sustainable human presence on the Moon and the eventual exploration of Mars.

The reassignment of astronauts and the delays in the Crew-9 mission are not unprecedented in the history of space exploration. Human spaceflight has always been fraught with risks, and NASA has a long history of making difficult decisions to ensure the safety of its astronauts.

One of the most notable examples of this was the Apollo 13 mission in 1970, where an oxygen tank explosion forced NASA to abort the mission and bring the crew home safely. The successful return of the Apollo 13 astronauts, despite the severe challenges, is a testament to NASA’s ability to manage risks and adapt to unforeseen circumstances.

Similarly, the tragic losses of the Space Shuttle Challenger in 1986 and Columbia in 2003 led to significant changes in NASA’s approach to human spaceflight. These disasters prompted a thorough re-evaluation of safety protocols and the development of new technologies to minimize the risks associated with space travel.

In the context of the Crew-9 mission and the Boeing Starliner challenges, NASA’s decision to prioritize astronaut safety reflects the lessons learned from these past experiences. The agency’s cautious approach is a reminder that, despite the advances in technology, space exploration remains an inherently dangerous endeavor.

Conclusion

The decision by NASA to drop two astronauts from the SpaceX Crew-9 mission in favor of accommodating those from Boeing’s troubled Starliner mission reflects the challenges and risks of human spaceflight. As the space agency navigates these difficulties, it remains committed to ensuring the safety of its astronauts and advancing its long-term goals in space exploration. The ongoing collaboration between NASA, SpaceX, Boeing, and international partners will be crucial in overcoming these challenges and pushing the boundaries of what is possible in space.

The Reason SpaceX Crew Dragon Was Selected for Sunita Williams’ Return

Eighty days after launching from Cape Canaveral Space Force Station in Florida aboard Boeing’s Starliner mission, astronauts Sunita Williams and Butch Wilmore were scheduled to return to Earth. However, their return journey faced significant delays due to technical issues with the Starliner spacecraft. These problems, primarily helium leaks and thruster malfunctions, posed considerable risks, leading NASA to explore alternative solutions.

The Decision to Switch to SpaceX’s Crew Dragon

With safety as the top priority, NASA ultimately decided to switch from Boeing’s Starliner to SpaceX’s Crew Dragon for the astronauts’ return. This decision was influenced by several factors, including SpaceX’s proven track record in human spaceflight. Since 2020, Crew Dragon has successfully transported multiple crews to and from the International Space Station (ISS), earning a reputation for reliability and safety.

NASA Administrator Bill Nelson highlighted the agency’s extensive experience with spaceflight, both successful and unsuccessful, as a critical factor in their decision-making process. He stated, “Spaceflight is risky, even at its safest and even at its most routine. And a test flight, by nature, is neither safe, nor routine.” NASA’s careful consideration of past experiences, including the tragic loss of two space shuttles, underscored the importance of a robust safety culture where information can be shared openly and without hesitation.

Boeing’s Starliner program has faced numerous challenges over the years. Despite being a key player in NASA’s Commercial Crew Program, the spacecraft has struggled with technical issues that have delayed its progress. The latest setbacks, involving helium leaks and thruster problems, raised serious concerns about the Starliner’s readiness for a safe return mission.

Helium Leaks: One of the critical issues with the Starliner was the helium leaks in its propulsion system. Helium is used to pressurize the fuel tanks, and any leakage can lead to a significant reduction in the spacecraft’s ability to maneuver safely.
Thruster Malfunctions: In addition to the helium leaks, the Starliner experienced thruster malfunctions. Thrusters are essential for controlling the spacecraft’s orientation and performing maneuvers, especially during re-entry and landing. Any malfunction in this system could jeopardize the safety of the astronauts onboard.

Due to these unresolved issues, NASA deemed it too risky to bring Williams and Wilmore back to Earth using the Starliner. Instead, they opted for SpaceX’s Crew Dragon, a spacecraft with a proven safety record.

SpaceX’s Proven Track Record

SpaceX has been a key partner in NASA’s human spaceflight efforts since the early 2000s. The company’s Crew Dragon spacecraft has played a vital role in NASA’s Commercial Crew Program, successfully transporting astronauts to and from the ISS since 2020.

Since then, SpaceX has conducted multiple crewed missions, demonstrating the spacecraft’s reliability and safety. Over the past four years, Crew Dragon has carried a dozen crews to and from the ISS, solidifying its position as a reliable workhorse for human spaceflight.

Gwynne Shotwell, SpaceX’s President and Chief Operating Officer, expressed the company’s commitment to ensuring the safe return of Williams and Wilmore. She stated, “SpaceX is ready to work with NASA to bring back astronauts Butch Wilmore and Suni Williams on the Crew Dragon spacecraft. We are fully committed to supporting NASA in any way necessary to ensure the success of this mission.”

Reconfiguring the Crew-9 Mission

The decision to use Crew Dragon for the return mission required significant adjustments to SpaceX’s upcoming Crew-9 mission. Originally scheduled as a routine mission to transport a four-person crew to the ISS, Crew-9 will now be reconfigured to accommodate Williams and Wilmore.

Revised Crew Composition: To make room for the returning astronauts, SpaceX and NASA will need to revise the crew composition for the Crew-9 mission. This means selecting which astronauts will not fly to the ISS as initially planned and ensuring that the spacecraft can safely accommodate the additional passengers.
New Spacesuits and Supplies: Along with the crew adjustments, new Dragon spacesuits for Williams and Wilmore will be sent to the ISS in the coming months. These suits are designed specifically for the Crew Dragon spacecraft and are essential for ensuring the astronauts’ safety during the return journey. Additionally, other necessary supplies will be sent to the ISS to prepare for the reconfigured mission.

NASA’s Focus on Safety

NASA’s decision to switch from Starliner to Crew Dragon underscores the agency’s unwavering commitment to safety in human spaceflight. The agency conducted a thorough review of its options, considering the risks associated with each spacecraft and drawing on its extensive experience with spaceflight.

NASA Administrator Bill Nelson emphasized the importance of a strong safety culture within the agency. He pointed out that NASA’s past failures, including the loss of two space shuttles, were partly due to a lack of open communication and a culture that did not prioritize safety above all else. “We lost two space shuttles as a result of there not being a culture in which information could come forward,” Nelson said.

SpaceX’s Collaboration with NASA

The successful collaboration between SpaceX and NASA has been a key factor in the success of the Commercial Crew Program. Since the early days of the partnership, both organizations have worked closely together to develop and certify the Crew Dragon spacecraft for human spaceflight.

Joint Testing and Certification: The partnership between SpaceX and NASA has involved rigorous testing and certification processes to ensure the safety and reliability of the Crew Dragon spacecraft. These efforts have paid off, with Crew Dragon successfully completing multiple crewed missions without any major incidents.
Continued Collaboration: As SpaceX prepares for the reconfigured Crew-9 mission, the company will continue to work closely with NASA to ensure that all safety protocols are followed and that the mission is a success. This collaboration includes ongoing communication between SpaceX’s engineers and NASA’s mission control teams, as well as joint decision-making on critical aspects of the mission.

While the decision to switch to Crew Dragon is a setback for Boeing’s Starliner program, it does not mark the end of the road for the spacecraft. NASA and Boeing remain committed to resolving the technical issues plaguing the Starliner and ensuring that it can be safely used for future missions.

Boeing has already begun work on addressing the helium leaks and thruster malfunctions that led to the recent delays. The company is also conducting a thorough review of the spacecraft’s systems to identify any other potential issues that could affect its performance.

Empty Return Flight: To further assess the Starliner’s performance and safety, Boeing plans to fly the spacecraft back to Earth empty in early September. This uncrewed return flight will allow the company to test the spacecraft’s systems without risking the safety of any astronauts.
Continued Development and Testing: Following the empty return flight, Boeing will continue to work on improving the Starliner, with a focus on addressing the issues identified during the recent mission. The company is committed to working with NASA to ensure that the Starliner meets all safety requirements and is ready for future crewed missions.

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.

Steve Stich, Program Manager for NASA’s Commercial Crew Program, highlighted the concern by stating, “There was too much risk for the crew. Our primary focus is on ensuring the safety of our astronauts.” The decision was made to bring the astronauts home aboard a different spacecraft, specifically SpaceX’s Crew Dragon 9.

Modifications to the Crew Dragon 9 Mission

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.

NASA Explores Solutions to Return Boeing Starliner Crew Safely

Eight weeks after the Starliner spacecraft launched, NASA is still looking for possible answers to its technical issues—including the possibility of SpaceX lending a hand.

It has now been eight weeks since Boeing’s Starliner spacecraft launched into orbit on an Atlas V rocket, bound for the International Space Station. At the time, NASA officials said the two crew members, Butch Wilmore and Suni Williams, could return to Earth as soon as June 14, just eight days later.

Yes, there had been some problems on Starliner’s ride to the space station that involved helium leaks and failing thrusters. But officials said they were relatively minor and sought to downplay them. “Those are pretty small, really, issues to deal with,” Mark Nappi, vice president and manager of Boeing’s Commercial Crew Program, said during a post-docking news conference. “We’ll figure them out for the next mission. I don’t see these as significant at all.”

But days turned to weeks, and weeks turned to months as NASA and Boeing continued to study the two technical problems. Of these issues, the more pressing concern was the failure of multiple reaction control system thrusters that are essential to steering Starliner during its departure from the space station and setting up a critical engine burn to enter Earth’s atmosphere.

In the last few weeks, ground teams from NASA and Boeing completed testing of a thruster on a test stand at White Sands, New Mexico. Then, last weekend, Boeing and NASA fired the spacecraft’s thrusters in orbit to check their performance while docked at the space station. NASA has said preliminary results from these tests were helpful.

Dragon Becomes a Real Option

One week ago, the last time NASA officials spoke to the media, the agency’s program manager for commercial crew, Steve Stich, would not be drawn into discussing what would happen should NASA conclude that Starliner’s thrusters were not reliable enough for the return journey to Earth.

“Our prime option is to complete the mission,” Stich said one week ago. “There are a lot of good reasons to complete this mission and bring Butch and Suni home on Starliner. Starliner was designed, as a spacecraft, to have the crew in the cockpit.”

For a long time, it seemed almost certain that the astronauts would return to Earth inside Starliner.

However, there has been a lot of recent activity at NASA, Boeing, and SpaceX that suggests that Wilmore and Williams could come home aboard a Crew Dragon spacecraft rather than Starliner. Due to the critical importance of this mission, Ars is sharing what we know as of Thursday afternoon.

One informed source said it was greater than a 50-50 chance that the crew would come back on Dragon. Another source said it was significantly more likely than not they would. To be clear, NASA has not made a final decision. This probably will not happen until at least next week. It is likely that Jim Free, NASA’s associate administrator, will make the call.

Asked if it was now more likely than not that Starliner’s crew would return on Dragon, NASA spokesperson Josh Finch told Ars on Thursday evening,

“NASA is evaluating all options for the return of agency astronauts Butch Wilmore and Suni Williams from the International Space Station as safely as possible. No decisions have been made, and the agency will continue to provide updates on its planning.”

What follows are some data points that Ars can confidently report based on multiple sources:

NASA keeps delaying a decision: A Flight Readiness Review meeting had been scheduled for today, August 1, several days in advance. However, it was canceled. Instead, NASA put out a vague blog update on Thursday stating, “Following the completion of Starliner’s return planning, which is expected to continue into next week, more information will be shared about the agency’s return readiness review preparations and subsequent media briefing.” So maybe the meeting will take place next week.
NASA issued a $266,678 task award to SpaceX on July 14 for a “special study for emergency response.” NASA said this study was not directly related to Starliner’s problems, but two sources told Ars it really was. Although the study entailed work on flying more than four crew members home on Crew Dragon—a scenario related to Frank Rubio and the Soyuz MS-22 leaks—it also allowed SpaceX to study flying Dragon home with six passengers, a regular crew complement in addition to Wilmore and Williams.
SpaceX has been actively working on a scenario in which two or four astronauts launch on board Crew 9: (A normal crew is four) This mission has a nominal launch date of August 18, but it could well be delayed. SpaceX has already identified flight suits that would fit Wilmore and Williams, allowing them to fly home on the Crew-8 spacecraft (presently docked to the space station) or the Crew-9 vehicle. It is unclear how crews would be assigned to the two Dragon return flights. It is possible, if four astronauts launch on Crew 9, that five people could fly home on each of the two Dragons.
Two sources told Ars that in meetings this week at NASA field centers, there have been vigorous discussions about whether or not to fly crew home on Starliner: Multiple groups remain “no” on Starliner as of Wednesday. It is unclear how this will be resolved. Some engineers believe that if there are questions about Starliner, then NASA should opt for the safe course—flying on Crew Dragon, which has safely launched 13 times and landed 12 times.

Making Difficult Calls

NASA officials face a difficult decision. Because there is still at least a small risk to flying Starliner in its present condition, the space agency and Boeing have tested the thrusters as thoroughly as possible while the spacecraft is docked to the space station. This testing was intended to “buy down” these risks. But while the data is good, it has not addressed all of NASA’s concerns.

So what will the space agency do? Starliner probably could make it back to Earth safely. But there appears to be some reasonable doubt that Starliner will come back safely. If NASA defers to its fallback plan, flying on Dragon, it may spell the end of the Starliner program. During the development and testing of Starliner, the company has already lost $1.6 billion. Reflying a crew test flight mission, which likely would be necessary should Starliner return autonomously, would cost much more. Boeing might opt to cancel Starliner and leave NASA with just a single provider of crew transportation. That would be painful for both NASA and Boeing.

But the alternative—Starliner not coming home safely with the crew inside—is far, far worse. This is the risk-reward decision that Free, Stich, and other NASA officials ultimately must balance in the coming days.
