The much-anticipated Boeing Starliner crewed mission encountered an unexpected setback. It was abruptly scrubbed just before liftoff on Monday. 

The decision was made due to concerns regarding an oxygen relief valve, marking another delay in the spacecraft's test journey to certify it for future manned missions.

The Scrubbed Launch

The United Launch Alliance (ULA) made the tough call to abort the launch of the Starliner mission just moments before liftoff, citing concerns over an oxygen relief valve on the Centaur Stage of the Atlas V rocket. 

Both astronauts, Suni Williams and Butch Wilmore, were already strapped into the capsule, heightening the tension surrounding the last-minute cancellation. The decision was made "over an abundance of caution," emphasizing the priority of crew safety in space missions.

Starliner Crewed Mission

Both Wilmore, 61, and Indian-origin Williams, 58, have already spent time on the International Space Station.

The seasoned astronauts both have impressive spaceflight experience. With past missions to the International Space Station under their belts, they were poised to conduct tests and maneuvers crucial for certifying the Starliner spacecraft for future manned flights.

Technical Challenges and Delays

Boeing's Starliner project has faced a series of setbacks since its inception, with the first crewed mission already four years behind schedule.

 The initial uncrewed orbital test flight in 2019 encountered issues, resulting in a failure to reach the International Space Station. Subsequent attempts were plagued by technical glitches, including valve malfunctions and parachute faults, further delaying the program's progress.

Ten years ago, NASA first approved Boeing and Space X to construct spacecraft that would fly from the United States to the ISS. Boeing received a $4.2 billion contract, while NASA gave SpaceX $2.6 billion. 

Boeing vs SpaceX

Since then, Boeing and SpaceX seem to have contrasting trajectories in the race for space dominance. 

NASA has spent the money to design and build Starliner, with Boeing adding another $1.5 billion in development costs. 

The Starliner can carry up to four astronauts to low-Earth orbit where they can use manual or automatic steering to maneuver it. The capsule is designed to be used for up to 10 missions.

SpaceX has been actively delivering cargo to and from the International Space Station (ISS) since 2012. It has a total of 46 successful launches (35 governmental and 11 commercial). 

Then, the Elon Musk owned company began transporting astronauts to the orbiting laboratory under NASA’s Commercial Crew Program in 2020. It launched 12 crewed flights to space, seven for NASA and four for commercial customers.

SpaceX has achieved notable success by expanding its Crew Dragon spacecraft from 1 to 4. The competitive landscape underscores the challenges and innovations driving the aerospace industry forward.

Despite this latest setback, NASA, Boeing, and ULA remain committed to resolving the technical issues and resuming the Starliner crewed mission. With potential launch opportunities in the coming days, the teams are taking a cautious approach to ensure the safety and success of the mission.
