NASA officials give tongue to confidence that Starliner will have a safe and successful return to Earth late Friday evening , though they had enough qualification about the spacecraft ’s performance to conclude that the trip should be undertaken without man on board .
The mellow - interest foreign mission is now set to formally close on Friday , with Starliner making its undocking attack around 6:04 p.m. EST . Should all go to programme , the space vehicle will land at New Mexico ’s White Sands Space Harbor approximately six hour after .
These final maneuvers will bring to a close a riotous first crewed mission for the Boeing - made Starliner . It was mean to be the terminal certification mission before the vehicle could figure operation as a even transporter for spaceman traveling to and from the International Space Station . But technical problems , include offspring with several of the spacecraft ’s pusher and a handful of He leaks in the propulsion systems , crop up shortly before the fomite attempted to dockwith the station on June 6 .
The two astronauts onboard , Butch Wilmore and Suni Williams , ended up boarding the ISS safely . But the issues finally extended the mission by several calendar month as NASA and Boeing engineers work to taste to determine the origin cause of the anomalies . After weeks of testing , both on the ground using reproduction hardware and on reach , NASA in the end adjudicate on August 24that Starliner should return to Earth empty , and Wilmore and Williams will come home using a SpaceX capsule in February 2025 or else .
The return slip will have one major difference from normal return missions from the ISS , which is that Starliner will conduct what ’s telephone a “ breakout burn ” to apace move it up and away from the station . This tactical manoeuvre — which is actually 12 minor suntan , with an orbital velocity of just 0.1 meter per second each — will see the pusher pulsing for a shorter period of time than they did during the approach shot to the station . For this ground , the breakout sunburn will likely not cause the same problem as railroad engineer follow at the start of the mission , and thus pose no rubber threat to the ISS , said Steve Stich , NASA ’s commercial-grade bunch program managing director , during a news conference .
“ The reasons we take doing this breakout suntan is it get the vehicle away from station faster , ” he sound out . “ Without the gang on board , able to take manual control if needed , there ’s just a lot less variables we need to account for when we do the breakout burn , and it allows us to get the vehicle on the flight home that much preferably . ”
The next critical maneuver will be the 60 - 2d deorbit burn , which will put Starliner into Earth ’s ambiance and en route to White Sands . The space vehicle will deploy parachute and airbags to make a indulgent landing on the terra firma .

“ We promise a good suntan , and we have a lot of redundancy , and that ’s what we ’re relying on to have a safe entry , ” he add .
NASA and Boeing will go through a few calendar month of post - flight psychoanalysis of the spacecraft ’s carrying out , but Stich say the team are already look at modifications to the organisation or extra testing to get the fomite in full certified by the quad bureau .
But it ’s unclear what the ultimate path will be to certify the space vehicle — let alone how much more it might cost Boeing , which has already receive cost totaling more than $ 1.5 billion related to the Starliner programme . It ’s also unclear whether Boeing would need to do another crewed test delegation .
If NASA and Boeing ’s joint flight control squad decide not to perform the undock on Friday , there will be several other opportunities in the coming day . Astronauts onboard the space station have modified the SpaceX Dragon fomite that ’s presently attached to the station with temporary seats in case of an parking brake .
