Originally set to return in mid-June, Barry Wilmore and Sunita Williams may be on the station until February, 2025.
During a press conference today, NASA representatives confirmed they have a contingency plan to bring astronauts Barry Wilmore and Sunita Williams home from the International Space Station (ISS) early next year. If they’re unable to leave sooner aboard the Boeing Starliner spacecraft that brought them there
Tests conducted at NASA’s White Sands Test Facility pointed to deformed Teflon seals being a potential cause of the Starliner’s thrusters failing, but the agency isn’t expected to make a final decision on whether or not Williams and Wilmore will return using Boeing’s spacecraft until mid-August.
Yes and no. One of the problems right now is each of the three capsule designs uses a different pressure suit, with different hookups, and each relies on a custom fitted seat liner to absorb some of the shock of landing / splashdown, so if you’re planning on landing on a different ship then you launched on, they need to send up a new seat liner & space suit.
This was half a problem even with the shuttle. You still needed a different spacesuit, but because it landed gently on a runway, it didn’t require custom seats.
The industry gossip/theory going around is that there’s a software issue in Starliner that makes it incapable of autonomously returning to Earth. This is probably NASA’s way of telling Boeing to fix it to a satisfactory degree of confidence before a given deadline, or else.
Arguably that alone is enough reason to completely abandon Starliner as an option for the return trip.
It's only an issue in that the logic isn't currently turned on. The capsule can do it just fine. It just wasn't the point of this mission.
NASA update earlier today said Boeing can turn the ability on if needed. Will just need time for update and then testing to make sure it's all good to go.
It takes no fewer than 4 weeks (!!!) to “turn the logic on”. The software that is currently loaded on Starliner cannot autonomously return - they will have to reflash the entire system.
It seems like there is disagreement within NASA whether it is safe for the astronauts to return on Starliner or not.
Boeing engineers did test on the ground to try to replicate the issue that is occuring on the thrusters. They found thqt the issue isndue to a Teflon seals bulging but they don't understand precisely why is the seal buldging and when it occurs.
However they feel confident enough that the problem would not happen on the way back to earth. Some people are NASA are not as confident as they are and would like to know the precise cause of the bulging.
About the software: there is a capability in the software for the capsule to undock autonomously.
However it would means resurrecting parameters that have not been used and updated since 2022, there is some reconfiguration needed and testing to make sure it still does what is needed despite the different hardware and software change that happened since then.
It is really not looking good for Boeing right now and I don't know if the Starliner program will survive this accident.
I get that being trapped in a tube that is essentially a tiny little bubble of habitable area in the vast, hostile, emptiness of space can already be super claustrophobia inducing and they are vetted and trained for that. But it seems once you are up there and you realize the world's leaders in space, and the people that sent you can't figure out how to get you home, that would trigger that panic in anyone. If there is an emergency you have no escape and there is no rescue coming.
If there is an emergency you have no escape and there is no rescue coming.
In the case of emergency they will jump into the Starliner and go. And they’ll probably be fine.
If Scott Manley is to be trusted (and I think he is), what’s likely happening is that the probability of failure has gotten higher than the mission parameters. Still very low, but higher than what was planned.
Uh oh astronauts... SpaceX "might have" gone to Mars starting in 2017 was it? They "might have"done a lot of things they they never actually done... Save that oxygen, astronauts.
What's your reasoning behind the claim that a company that's been transporting crew to and from the ISS for 4 years, and currently has a vehicle docked to the station, is incapable of launching a tenth mission? Mind that said mission was supposed to launch next week, but Starliner is being a pad princess in orbit and won't get off the required docking port.
Scott Kelley did 340 days in space without too much long term damage that I am aware of (his was the first long term test) so I wouldn't anticipate damage much worse than what he got. If we can get them out in under a year and if they get don't have an emergency and if they don't have any underlying medical conditions that get exacerbated and if our single test can be used to predict their outcomes.
We really fucked up. Either trusting Boeing or not having a contingency plan I guess.
It's certainly not great for their eyes, but a number of people have been up for longer in one go. I think Frank Rubio currently holds the record at ~14 months.
