Elon Musk Says FAA Should Make Boeing Pay for Putting Starliner Astronauts at Risk, Not Fine SpaceX

By Jonathan Bala September 20, 2024

Elon Musk Says FAA Should Make Boeing Pay for Putting Starliner Astronauts at Risk, Not Fine SpaceX

Elon Musk recently criticized the Federal Aviation Administration (FAA) for proposing fines against SpaceX instead of focusing on safety issues with Boeing’s Starliner. Musk emphasized that Boeing’s Starliner spacecraft had put astronauts at risk, yet the FAA was fining SpaceX over what he called “trivial” violations. Musk called on the FAA to redirect its focus and hold Boeing accountable for safety failures.

Summary

Elon Musk publicly criticized the FAA for fining SpaceX over minor infractions while ignoring safety concerns with Boeing’s Starliner.
The FAA proposed a $633,009 fine against SpaceX for violating launch licenses during two launches in 2023.
SpaceX used an unapproved launch control room and rocket propellant farm during those missions.
Musk accused the FAA of focusing on “petty matters” that didn’t involve safety, while Boeing’s Starliner program jeopardized astronaut safety.
Boeing’s Starliner spacecraft has faced multiple safety issues, including thruster malfunctions and helium leaks.
Musk highlighted that NASA had turned to SpaceX’s Crew Dragon for astronaut returns due to concerns with Boeing’s Starliner.
Despite Boeing’s issues, the FAA has yet to fine the company, which Musk sees as a clear double standard.
SpaceX has completed multiple successful missions, including the Polaris Dawn mission and the world’s first commercial spacewalk.
Musk and SpaceX have had ongoing disputes with the FAA over delays, safety concerns, and environmental regulations.
Musk suggests that the FAA’s actions may be influenced by external pressure and not genuine safety concerns.

Elon Musk’s Response to FAA Fines

On September 6, 2023, the FAA proposed a $633,009 fine against SpaceX for violations related to launch licenses. These violations occurred during two separate launches in 2023. The FAA accused SpaceX of using an unapproved launch control room and an unapproved rocket propellant farm during these missions.

In response, Elon Musk expressed his frustration with the FAA’s decision. In a post on X, Musk accused the FAA of focusing on “petty matters” and ignoring real safety concerns with Boeing’s Starliner program. He tweeted, “NASA deemed the Boeing capsule unsafe for astronaut return, turning, out of necessity, to SpaceX, yet instead of fining Boeing for putting astronauts at risk, the FAA is fining SpaceX for trivia!”

Musk’s frustration stems from what he sees as a clear double standard. While SpaceX is being penalized for minor infractions, Boeing’s Starliner spacecraft has faced significant safety concerns, including thruster malfunctions and helium leaks.

For more details on the FAA’s fine, check out their official announcement on their website here.

The Boeing Starliner spacecraft has faced numerous technical issues, most notably during its mission in June 2023. After docking with the International Space Station (ISS), the spacecraft experienced thruster issues and helium leaks, which delayed the return of astronauts Butch Wilmore and Suni Williams. As a result, NASA opted to use SpaceX’s Crew Dragon for future astronaut returns, citing safety concerns with the Starliner.

Boeing has faced scrutiny over its ability to deliver a safe spacecraft, and yet the FAA has not issued fines against the company. Musk’s frustration is partly due to the fact that Boeing, despite its safety issues, has escaped financial penalties.

For more on Boeing’s Starliner challenges, see thisSpaceX update.

Elon Musk Says FAA Should Make Boeing Pay for Putting Starliner Astronauts at Risk, Not Fine SpaceX

Musk’s History of Disputes with the FAA

This isn’t the first time Musk has had issues with the FAA. SpaceX recently criticized the FAA for delaying the launch of its Starship vehicle, pushing the mission from mid-September to late November. In a statement, SpaceX accused the FAA of unnecessary delays, stating that the delay was “driven by superfluous environmental analysis” rather than actual safety concerns.

SpaceX also said the delays were based on “false and misleading reporting” by online detractors and special interest groups. Musk has often voiced his concerns over what he sees as bureaucratic inefficiencies within the US government, even floating the idea of joining a potential Trump administration to lead a new Department Of Government Efficiency (DOGE) if the former president wins the next election. You can read more about Musk’s involvement with the government in this article.

For further updates on SpaceX’s progress, visit the officialSpaceX updates page.

Despite its ongoing disputes with the FAA, SpaceX continues to make groundbreaking strides in space exploration. In September 2023, SpaceX successfully completed the Polaris Dawn mission, which involved a crew of four non-astronauts. During this mission, the crew conducted the world’s first commercial spacewalk, further cementing SpaceX’s reputation as a pioneer in the commercial space sector.

Meanwhile, Boeing’s Starliner spacecraft has yet to prove itself as a reliable alternative. While it has completed a handful of missions, technical malfunctions and safety concerns continue to plague the spacecraft, delaying its progress in NASA’s Commercial Crew Program. Musk has pointed out that SpaceX’s Crew Dragon finished development “4 years sooner” than Starliner, as he noted in a May 2023 X post.

Musk’s criticism of the FAA is not solely about SpaceX. He argues that the regulatory body is not holding Boeing accountable for serious safety concerns. In fact, NASA itself has expressed concerns over Starliner’s readiness. NASA deemed the spacecraft unsafe for astronaut return, which is why astronauts Wilmore and Williams will return to Earth in February 2025 via SpaceX’s Crew Dragon.

Musk’s demand for fairness and accountability is at the heart of his rebuke of the FAA. He believes that Boeing should face penalties for its shortcomings, rather than SpaceX being fined for what he calls “trivial” matters. In a letter to top congressional leaders, SpaceX forcefully rejected the FAA’s accusations, stating that “these distractions continue to directly threaten national priorities and undercut American industry’s ability to innovate.” You can read more about this letter and Musk’s rebuke in this Business Insider article.

As the space race between SpaceX and Boeing continues, Musk’s latest comments highlight the broader debate over regulation and innovation. While SpaceX has repeatedly proven its ability to deliver successful missions, Boeing’s Starliner program still faces significant challenges.

Moving forward, it remains to be seen how the FAA will respond to Musk’s criticisms and whether Boeing will face further scrutiny. What is clear is that spaceX’s continued innovation, despite regulatory hurdles, has made it the dominant force in the commercial space industry.

Elon Musk’s call for accountability from the FAA shines a light on the broader issues of regulation and safety in the commercial space industry. While SpaceX continues to push the boundaries of space exploration, Boeing’s Starliner spacecraft has faced repeated setbacks and safety concerns. As the space race continues, the FAA must ensure that all companies, including Boeing, are held to the same safety standards.

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.

Crew Dragon first made headlines in 2020 when it completed its first crewed test flight, earning NASA’s certification for operational missions. 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.

Table 1: Key Events in Starliner’s Mission

Date	Event	Description
Launch	Eight weeks ago	Starliner launched on an Atlas V rocket.
Initial Issues	Shortly after launch	Helium leaks and failing thrusters detected.
Testing	Last few weeks	Ground and in-orbit thruster tests conducted by NASA and Boeing.
Task Award	July 14	NASA issued a task award to SpaceX for emergency response study.
Flight Review	Scheduled for August 1	Flight Readiness Review meeting scheduled and later canceled.

Table 2: Potential Scenarios for Crew Return

Scenario	Description	Likelihood (As of Now)
Return on Starliner	Crew returns on the original Starliner spacecraft.	Less than 50%
Return on Crew Dragon (Crew-8)	Crew returns on the Crew-8 spacecraft currently docked at the space station.	Significant possibility
Return on Crew Dragon (Crew-9)	Crew returns on the Crew-9 spacecraft scheduled for launch on August 18.	Possible, if launch occurs
Mixed Crew Dragon Scenario	A combination where some crew return on Crew-8 and others on Crew-9.	Under consideration

Conclusion

NASA faces a challenging decision in determining the safest way to return the Starliner crew. With ongoing concerns about Starliner’s thrusters, the reliable alternative of SpaceX’s Crew Dragon is being seriously considered. The ultimate choice will have significant implications for both NASA and Boeing, balancing safety, risk, and the future of the Starliner program.
