Boeing is set to make one other try to attain the International Space Station with its Starliner capsule Thursday, almost two and a half years after the firm’s first mission fell quick.
Boeing has been creating its Starliner spacecraft underneath NASA’s Commercial Crew program, having received almost $5 billion in contracts to construct the capsule. The firm competes underneath the program towards Elon Musk’s SpaceX, which accomplished growth of its Crew Dragon spacecraft and is now on its fourth operational human spaceflight for NASA.
Boeing’s growth of Starliner has run into a number of obstacles over the previous three years.
Its first uncrewed mission in December 2019, known as the Orbital Flight Test (OFT), ended prematurely after a software malfunction saw the capsule end up in the wrong orbit. NASA famous earlier this yr, after an investigation into the situation, that Boeing’s software program growth “was an space the place we could haven’t had fairly as a lot perception and oversight as we should always have had.”
Boeing tried to launch the second orbital flight take a look at, or OFT-2, in August, however the company discovered a propulsion valve problem whereas the spacecraft was nonetheless on the floor. Thirteen of the 24 oxidizer valves that management Starliner’s motion in space acquired caught after launch-site humidity induced corrosion, and the spacecraft’s service module was changed.
Boeing has now utilized a sealant to the valves and is scheduled to make one other try at launching OFT-2 on Thursday at 6:54 p.m. ET.
An Atlas V rocket from United Launch Alliance will carry Starliner to orbit, when it’ll start a 24-hour journey earlier than docking with the ISS. The mission is anticipated to final a couple of days in complete earlier than the capsule returns to Earth.
The U.S. Space Force’s forty fifth Weather Squadron forecast situations to be probably clear for launch, with the potential for disruption from scattered thunderstorms round Florida’s Cape Canaveral. A back-up launch time is scheduled for Friday, though the climate forecast deteriorates considerably then.

The aerospace large was as soon as seen as evenly matched with SpaceX in the race to launch NASA astronauts. Yet the delays to Starliner’s growth have steadily set Boeing again, each in schedule and funds.
Due to the fixed-price nature of its NASA contract, Boeing absorbed the value of extra work on the capsule – with $595 million spent by the firm up to now.
NASA final yr took the rare move of reassigning astronauts from Starliner to SpaceX’s Crew Dragon. The company additionally final yr introduced it intends to buy three extra crew flights from SpaceX, which might put Musk’s firm on observe to probably end its authentic NASA contract of six flights earlier than Starliner even carries a crew as soon as.
If Thursday’s OFT-2 launch is profitable, Boeing would then put together for a crewed flight take a look at that will see the first astronauts fly on Starliner.
Boeing vice chairman Mark Nappi mentioned in a pre-launch press convention that the firm “might probably be prepared” for the crewed flight “by the finish of this yr.” Still, the firm is analyzing whether or not to redesign the Aerojet Rocketdyne-made valves on Starliner, which might additional delay crewed launches.
NASA’s Commercial Crew supervisor Steve Stich mentioned the company would not see a redesign of the Starliner valves as a “massive deal from a certification perspective.” NASA would work with Boeing to “work out what sort of testing wants to happen” in the occasion of a redesign, Stich famous, with a schedule but undefined for “how lengthy it will take.”
“Personally, I might love to see Starliner flying previous 2030 – I might love to see Dragon flying previous 2030. NASA made an enormous funding in each these automobiles and so they’re nice platforms to go to low Earth orbit,” Stich mentioned.
