Boeing's Starliner Landing: NASA Says Astronauts Would Have Been Fine
Boeing's Starliner spacecraft successfully returned from its Crew Flight Test (CFT) mission, parachuting to a soft landing in New Mexico. Although the mission experienced thruster issues, NASA confirmed that if astronauts had been on board, they would have been safe. This marks an important milestone in the spacecraft's journey to becoming an operational crew transport vehicle to the International Space Station (ISS). NASA's decision to return Starliner uncrewed was a cautious yet necessary step in ensuring crew safety for future missions.

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.
