NASA and Boeing are further extending the first Starliner crewed flight but are not yet setting a new target date for returning the capsule to Earth, the organizations announced on Friday. Boeing’s Starliner capsule “Calypso” will stay at the International Space Station into next month while the company and NASA conduct new testing back on the ground. Boeing’s crew flight test represents the first time Starliner is carrying people, flying NASA astronauts Butch Wilmore and Suni Williams. Officials say the Starliner team is starting a test campaign of the spacecraft’s thruster technology at White Sands, New Mexico – testing that will be completed before Starliner returns to Earth. Oof. Spaceship named “Calypso” who strands crew on ISS … Per wiki… In Greek mythology, Calypso (/kəˈlɪpsoʊ/; Greek: Καλυψώ 'she who conceals')[1] was a nymph who lived on the island of Ogygia, where, according to Homer's Odyssey, she detained Odysseus for seven years. She promised Odysseus immortality if he would stay with her, but Odysseus preferred to return home. |

SpaceX doesn’t have a Dragon ready to go. According the NASA, there are 6 docked at the ISS currently, that includes the Boeing pos. There are six docks total, so the ISS is full. I get the impression that some docks can only work with certain spacecraft. |

Quote HistoryOriginally Posted By RiverSwine45: Orion CM uses N2H4 and a catalyst ignition thruster (no OX propellant) and the Orion SM uses MMH and N2O4 in the thrusters. Interesting, I had to go googling for more info and discovered this is correct - monopropellant on the crew module. The service module (where the leaks and "thruster problem" are) uses fuel/oxidizer and does all the maneuvering until it is jettisoned prior to reentry. The crew module thrusters are (obviously) tiny and only used to maintain attitude during reentry, so monopropellant is very feasible for them. The service module can carry adequate helium/fuel to reach lunar orbit. Assuming it was launched with a full load of fuel/helium any leaks large enough to compromise an earth orbiting mission would have to be massive. Found info online that says: The helium leaks are in the service module plumbing/manifolding, so that 395psi/min leak rate is presumably for a small volume of plumbing, not from the supply tanks. The thruster concern is related to a service module oxidizer isolation valve that is not reporting that it is closed when it is commanded to close. One aspect I didn't consider is that the service module will be jettisoned and burn up - so you can't examine it after flight to determine what caused a problem. Found some info online that they are disassembling the next service module and inspecting for any clues as to the source of the leak(defective parts, bad assembly procedures, incorrect execution of procedures, etc). If there is any chance of getting more details about the problem then delaying the return is probably worthwhile. Significantly, news says that NASA has begun stating that starliner is not "stranded" over the weekend so they are at least aware of the public perception. |

Intentionally reporting leak rate as psi/minute is incompetence. A reporter writing that indicates "not competent to report". The person that supplied that information should have jumped on it right away and gotten a correction by the reporter. (395 psi/min)(24 hours/day)(60 min/hour) = 568800 psi/day. Let's see those storage tanks! The leaks should be reported as pounds-mass per minute, or seconds, or hours. And not constant without pumping something into the tanks to maintain pressure. |

The leaks should be reported as pounds-mass per minute, or seconds, or hours. And not constant without pumping something into the tanks to maintain pressure. We already covered this a week or two ago. The consensus was that the pressure was from a sensor somewhere in the plumbing.

Quote HistoryOriginally Posted By redoubt: Someone in this thread mentioned that there was a lower limit to the pressure that was needed to reliably push propellant and oxidizer to the thrusters against the chamber pressure.

Helium is always a gas at the pressures we are talking about(that's why it's used) so if you lose 1/2 the mass of gas you have 1/2 the pressure. From the reporting that is out there, the leak is in the plumbing and the tanks themselves are not leaking when the valves are closed. Surely there is some concern, but absent more details we can only speculate about what their concerns are. You don't test fire engines of a spaceship while it is in orbit and make it wait until your testing is complete before you give a greenlight for it to return - you do that before the spaceship takes off. So they are clearly concerned about something. |

That doesn't work for what you need. You'd report that as a 25 psi leak, because you're still getting the volume you wanted. Edited for clarity. |

Spaceship named “Calypso” who strands crew on ISS … Per wiki… In Greek mythology, Calypso (/kəˈlɪpsoʊ/; Greek: Καλυψώ 'she who conceals')[1] was a nymph who lived on the island of Ogygia, where, according to Homer's Odyssey, she detained Odysseus for seven years. She promised Odysseus immortality if he would stay with her, but Odysseus preferred to return home. It could be named as an homage to Cousteau's famous ship (... which was presumably named after the nymph). |

Incorrect. The starliner does not belong to the taxpayer anymore than the seat you ride in on Delta belongs to you. NASA is just paying for a ride. NASA paid $4.2 billion dollars to Boeing for the development of Starliner, which includes six operational flights. So no, it is NOTHING like buying a ticket for a seat on Delta, unless you also paid to develop and build the airplane that your seat is on. Yes, Starliner belongs to Boeing, but NASA (and the taxpayer) paid for its development and construction. |

That's a surprise and unusual. |

They are going to wait out the news cycle and let the fiasco disappear and then fetch the crew with a Dragon.
As far as what they will do with the capsule. It will limp away from the ISS, the deorbit burn will fail and it will be a mostly peaceful but fiery return. |

As far as what they will do with the capsule. It will limp away from the ISS, the deorbit burn will fail and it will be a mostly peaceful but fiery return. It's not like the deorbit burn can fail. It's deorbiting now w/ the ISS very, very slowly, which is why the ISS has to be reboosted periodically. It's that the deorbit process can take too long w/ the very little bit of aerobraking currently occurring at that altitude, meaning if it was crewed at the time they'd need rescuing before they ran out of O2. If we believe NASA/Boeing's claim that it could be used to deorbit right now in an emergency b/c the ISS suddenly became uninhabitable b/c something the size of a crew capsule crashed into it, then there are enough thrusters they're confident in working to do the deorbit burn. But no matter what, Boeing's not going to get the service module w/ the failing thrusters back, so they're trying to figure out the problem w/ this service module while it still exists. If we don't believe Boeing, NASA's not letting it depart the ISS for fear the astronauts might get stranded, or worse, it might impact the ISS on departure, meaning NASA might have to pay SpaceX sooner to deorbit the ISS b/c of a Boeing fuckup. |

Elon should explain he'd really like to help, but can't for various reasons. But Joe could pick up the phone and call Putin and ask him for a solid.

July 4th CO2 sensor issue, #Boeing.
 "CAPCOM update from this morning. The CO2 sensor in Starliner, apparently there is only one, behaved erratically overnight before finally failing off scale high and has been suppressed. Sunny was instructed to alter any possible future safe haven procedures to insert installation of lithium hydroxide scrubber canisters earlier. Sunny acknowledged and asked which canisters to use. 4 were used during launch/docking, 4 during the last safe haven and 8 remain. This exchange was at about 7 am eastern. The Starliner team was already off console and they did not inform the crew directly before departing." Transcript: 00:00:01 Houston Station Houston on two for Butch or Sunny at your convenience, go ahead. 00:00:08 Houston All right, Butch. I wanted to pass on one configuration change we made to CST overnight. We started seeing the CO2 sensor actor radically. It was jumping between a nominal value and an off scale high. It eventually tripped the fault for the PPCO2 high. So there's some tones and lights and alarm and. 00:00:28 Houston CST ecom has inhibited defaults associated and we'll continue looking into it. 00:00:35 Houston If that all makes sense, I do have 1D for your safe haven procedure. When you're ready to copy. 00:00:43 Butch So that was a single erratic sensor, just one sensor. 00:00:48 Houston That's correct. And that sensor is for CO2. 00:00:53 Butch I'll be ready to copy the delta. 00:00:56 Houston OK. So while we have these faults inhibited, if we were in another safe haven case, you would not receive a message for high PPCO2. 00:01:06 Houston And so as a result, we recommend that sunny perform the Liao steps. 00:01:12 Houston Before entering step 8, which is the first step in her column of the procedure. 00:01:20 Butch Right. So the Lyle steps, I think was at 13 before she does step 8. 00:01:28 Butch Yeah, sounds wise. Well, we find ourselves in that situation. We will definitely do that. Thank you. 00:01:35 Houston Absolutely. 00:01:37 Sunny Hey, just got a question too. Is there a CST ecom in the house? 00:01:42 Houston There is no longer one in the house. They were there a couple of hours ago. I can takedown a question, though, if you. 00:01:49 Sunny Quick question, if we by chance do safe Haven again, I'm just curious about what lyo canisters they'd want us to use, and we used four on the way here. I put 4 fresh ones in during safe haven. We've got eight more fresh ones. 00:02:09 Sunny But in case there's a safe haven event, would they want us to use the ones we used for less safe haven or break open for more? 00:02:17 Houston Copy the question. I'll pass it along. Might be able to get you an answer doing Houston business hours today, but would Friday be all? 00:02:25 Houston Right. 00:02:26 Sunny Yeah, that's great. I just, you know, just thinking ahead about what you just mentioned about the sensors and us putting it in there pretty quickly. So just curious about which would be the right ones to use? 00:02:38 Houston Yeah, I copied the question. All makes sense. 00:02:40 Sunny OK. Thanks. |
