Wilmore and Williams were present to assist with the detachment of Starliner from the space station.
“We’re cheering for you. You’re going to be fine,” Williams communicated to mission controllers at NASA’s Johnson Space Center in Houston before the capsule separated. “Bring us back to Earth. Best of luck.”
Starliner’s journey back will mark the end of a turbulent few months for Boeing and NASA, whose test flights were meant to show that the spacecraft could reliably transport astronauts to low Earth orbit and pave the way for NASA to approve Boeing for regular flights to the space station.
However, the issues with the thrusters are the latest setback for Boeing’s Starliner program, which is already more than $1.5 billion over budget and years behind schedule even before its first launch. An initial uncrewed test flight that NASA required before Boeing’s spacecraft could carry astronauts also failed, leading the company to try again in 2022.
NASA officials stated earlier this week that they are collaborating with Boeing to enhance Starliner’s thrusters, and further analysis will be conducted once the spacecraft returns and engineers evaluate its performance.
To prepare for a potential thruster malfunction as Starliner embarks on its return journey, flight controllers adjusted the capsule’s usual undocking process: After separating from the space station, Starliner would automatically move away from the station in case of any issues.
Preliminary data showed that the thrusters successfully completed all 12 scheduled burns during the retreat, according to NASA.
Several hours later, at 11:17 pm EST, Starliner’s engines will execute a 59-second “de-orbit burn,” decelerating the spacecraft and initiating its reentry into Earth’s atmosphere. As it nears the landing location in New Mexico, parachutes will be deployed to slow the capsule, with airbags beneath the spacecraft deployed to cushion the landing.
For Boeing, a successful return of the Starliner spacecraft will be mixed feelings: If all goes well, it could demonstrate that NASA astronauts could safely ride back on the spacecraft, although NASA’s senior leadership unanimously opted for SpaceX to handle the return flight to reduce the risk of further setbacks.
Boeing designed the Starliner spacecraft as part of NASA’s Commercial Crew Program, which began in 2011 to support private spacecraft in place of NASA’s retired space shuttle fleet. Competitor SpaceX is developing its Crew Dragon spacecraft under the same program, which has been conducting regular round-trip missions to the space station since 2020.
