Starliner's Space Station Flight Was 'Wilder' Than We Thought (arstechnica.com) 95

The Starliner spacecraft lost four thrusters while approaching the International Space Station last summer. NASA astronaut, Butch Wilmore took manual control, remembers Ars Technica, "But as Starliner's thrusters failed, Wilmore lost the ability to move the spacecraft in the direction he wanted to go..." Starliner had flown to within a stone's throw of the space station, a safe harbor, if only they could reach it. But already, the failure of so many thrusters violated the mission's flight rules. In such an instance, they were supposed to turn around and come back to Earth. Approaching the station was deemed too risky for Wilmore and Williams, aboard Starliner, as well as for the astronauts on the $100 billion space station.

But what if it was not safe to come home, either?

"I don't know that we can come back to Earth at that point," Wilmore said in an interview. "I don't know if we can. And matter of fact, I'm thinking we probably can't."

After a half-hour exclusive interview, Ars Technica's senior space editor Eric Berger says he'd heard "a hell of a story." After Starliner lost four of its 28 reaction control system thrusters, Van Cise and this team in Houston decided the best chance for success was resetting the failed thrusters. This is, effectively, a fancy way of turning off your computer and rebooting it to try to fix the problem. But it meant Wilmore had to go hands-off from Starliner's controls. Imagine that. You're drifting away from the space station, trying to maintain your position. The station is your only real lifeline because if you lose the ability to dock, the chance of coming back in one piece is quite low. And now you're being told to take your hands off the controls...

Two of the four thrusters came back online.

Wilmore: "...But then we lose a fifth jet. What if we'd have lost that fifth jet while those other four were still down? I have no idea what would've happened. I attribute to the providence of the Lord getting those two jets back before that fifth one failed...

Berger: Mission Control decided that it wanted to try to recover the failed thrusters again. After Wilmore took his hands off the controls, this process recovered all but one of them. At that point, the vehicle could be flown autonomously, as it was intended to be.

"Wilmore added that he felt pretty confident, in the aftermath of docking to the space station, that Starliner probably would not be their ride home," according to the article. And Williams says it was the right decision. Publicly, NASA and Boeing expressed confidence in Starliner's safe return with crew. But Williams and Wilmore, who had just made that harrowing ride, felt differently.

    I remember reading that the capsule suffered more thruster failures on the unmanned trip home, even though it was able to successfully re-enter atmosphere and land.

    I'd equate it to a 747 losing an engine and rudder control, managing to land and disembark passengers, then after "repairs" done by a small field tech with very limited tools, heads back without the passengers, but suffers another engine failure on the way back.

    If I was one of those passengers, I'd be 100% with not being on that flight back, even if it made it back "safely".

    Especially if I'm getting to spend another week in some tropical paradise* on the airline's dime waiting for another plane.

    As a note, the dragon capsules have a history now of working without serious failures.

      But it's so much worse than that!. The plane was so damaged that the only airport nearby wants to turn you away because they're afraid you're going to lose control, crash in to the terminal, and kill everyone at the airport if you try to land there.

      • .. which is why the terminals are over there, and the runway(s) are [points in a different direction] over there, separated by a maze of taxiways with speed limits, turns, and soft ground traps which will stop an out-of-control plane pretty much dead in the mud.

        It's called engineering. It doesn't happen by accident.

    • Fair analogy. Just substitute the rusk of causing, probably, fatal harm to the airport. The entire airport, on the attempted landing.

      And never had actually landed that 747 more than 3 times. All without passengers.

      Boeing flew this with a history of problems with the thrusters, apparently both the RCS and OMAC thrusters. 28 RCS thrusters. That seems complex.

      Not quite that bad. It's as if a 747 had 28 rudders, and four failed, when it needed five to keep control.

      Also point a 747 will fall out of the sky with loss of control, unlike spacecraft, which are in orbit.

      • by sjames ( 1099 )

        No. The thrusters on Starliner are not interchangeable. Right there in the summary, the pilot said that with 5 of them out, they would not be able to complete a docking maneuver with the station. So more like 28 control surfaces, but all of the ones offering yaw control went out.

        • The Starliner and every other Aircraft that Boeing makes should have its flight worthiness cancelled and have to get everything re-certified from scratch again.
  • Talk about a Major Tom moment! Wonder when Starliner will actually be safe for human travel...

      It's quite potentially "never", in the sense that NASA or Trump might "allow" them to exit their contract, cancelling further development of the system.

      Actually had a bit of an argument on that with somebody online not long ago, they were convinced that Musk would cancel the contract to save the fed money. They just couldn't seem to understand that Boeing has already been paid everything they're going to be paid for it, and are now burning through their own money to fulfill the contract at a major loss.
      As such, holding their feet to the fire to fulfill the contract actually "helps" Musk and SpaceX more, by making them bleed even more money. So I judged it unlikely.

      • Boeing is on the hook for Starliner, but what about the boosters NASA wastes on launching it?

        You should have lost that argument.

        It's a firm fixed price contract, with payments made at specific milestones. The actual contract, and the actual milestones, is not public information so there's always going to be some speculation involved in how much money is left on the contract that Boeing could get paid.

        But, speculating here, getting Starliner certified to carry NASA crew to the ISS is something that stands out as perhaps the most obvious milestone possible. If there's a milestone payment associated with that (likely, IMHO), they'll get that if they ever get certified. They'll also get paid for each NASA mission that goes to the ISS. So, IMHO, you're likely wrong with "Boeing has been paid everything they're going to get paid for". They're not getting any more money until they meet the next milestone, whatever that is.

        • The current one is to have a successful launch and dock at ISS. What they've done can't be considered a success. They're also running out of time before ISS is deorbited so it would be impossible after that.
        • The actual contract, and the actual milestones, is not public information

          The actual contract is here [nasa.gov], AFAICT, and it does list the specific milestones in considerable detail (see Appendix A) though the payment amounts and some of the acceptance criteria are redacted. There are quite a few milestones, and Boeing has at this point completed all but the last two milestones (Operational Readiness Review Interim Milestone, which includes the crewed flight test, and Certification Review Delivery Milestone).

          So... it appears to me that letting them out of the contract would save the

      Given Starliner's history of failure, 'm honestly in disbelief NASA even ALLOWED Starliner to launch with humans on board without requiring that it successfully make MULTIPLE successful unmanned supply runs to the ISS first.

      Maybe I'm mis-remembering, but I could SWEAR I remember SpaceX launching several Dragon capsules for unmanned ISS supply runs before its first manned launch.

      Regardless, that should be NASA's firm requirement for Starliner NOW... no humans until it successfully completes at least 2 or 3 unmanned supply runs to the ISS without serious incidents (with NASA paying Boeing the going rate for an ISS supply mission, regardless of how much more it actually costs Boeing to do it with a Starliner capsule.

        Crew Dragon is not the same as Cargo Dragon. My understanding is there are significantly more complex systems onboard Crew for life support, additional radiation shielding, communications, and internal controls for thrust, yaw, pitch, attitude, and roll (commonly referred to as RCS). Cargo doesnt have a lot of those additions and was therefore independently certified. Human rating is a different certification as well.

        SpaceX did have the crew dragon before they designed, built and flew the quite different Crew vessel. But the experience in building the cargo craft really helped them.

        Crew dragon flew one automatic flight with no crew, then one flight with two crew members, before beginning normal operations. These flights were not completely problem-free, but they still went remarkably smoothly.

        • "the experience in building the cargo craft really helped them."

          It certainly did, but it's not like Boeing lacked experience. In fact, early on there was a serious push for sole-sourcing the crew contract to Boeing based on their history with the Shuttle, that SpaceX was too inexperienced and couldn't be trusted to get the job done.

          • Anyone who designed the shuttle at boeing has long since retired.

        But, with that said, Musk is absolutely the chief visionary of SpaceX. He absolutely comes up with the direction of what he wants to see done, and then gives it to his engineers to turn it into steel. And it's been working.

        Musk is phenomenally good at what he does well, awful at others. "Wiser" is a value judgement. At the moment, I'd say he is not acting very wisely, because he has surrounded himself with yes-men who don't dare to every disagree with him on anything, because he fires anybody who disagrees on the spot. That does not seem wise to me.
