Boeing’s Starliner capsule to leave the International Space Station on Friday, without astronauts Butch Wilmore and Suni Williams

In a new episode of a real space soap opera, Boeing’s Starliner capsule leaves the International Space Station (ISS) on Friday, but returns to Earth empty-handed, without the two astronauts it had taken on the way there, due to concerns about the safety of the device.

The reputation of the American aeronautics giant – already dented by numerous recent problems with its airliners – took a further hit in June when thruster failures and helium leaks on the capsule were detected during the inaugural manned flight.

Despite the manufacturer’s attempts to convince NASA of the safety of its device, the space agency preferred to bring Butch Wilmore and Suni Williams back via Boeing’s competitor, SpaceX, and its Crew Dragon capsule. The two astronauts, who will not return until next year, will remain in space for more than eight months, whereas they were initially supposed to carry out a mission of… eight days.

NASA’s commercial human spaceflight program manager Steve Stich told reporters this week that despite Boeing’s confidence in its projections, the space agency “was not comfortable” proceeding with Starliner “because of the uncertainty around the model.”

A smooth return flight on Friday will be essential for the American manufacturer, not only for its own pride, but also for its future chances of obtaining new manned flight approvals.

“Better understanding”

Starliner will begin its autonomous undocking from the ISS shortly after 6 p.m. Eastern Daylight Time. It is scheduled to land at a base in New Mexico in the southwestern United States at 12:03 a.m. Saturday.

Ground teams will monitor Starliner’s performance in all aspects, particularly its thrusters — which have been experiencing problems — during the deorbit boost that allows it to re-enter Earth’s atmosphere.

Steve Stich assured that NASA was primarily focused on the immediate tasks at hand.

Once Starliner’s return is confirmed, “we’ll have a better understanding of when we can certify the aircraft and when we can resume flights,” he said.

NASA ordered a new spacecraft from Boeing and SpaceX ten years ago to each carry its astronauts to the ISS. With two vehicles, it wants to avoid being left without a solution in case of a problem with one or the other.

But Elon Musk’s company has largely beaten Boeing and has been acting alone as the American space taxi for four years now.

This first crewed flight of Starliner, carried out years late due to setbacks during its development, was to be the last test before beginning regular operations.
