I have no doubt the scrubliner is broken. The He leaks are a big deal because the gas pressurizes the hypergolic RCS. Without the He they can’t fire the thrusters to steer or de-orbit.
The “extra time” is off nominal for ANY space mission. |

Without the He they can’t fire the thrusters to steer or de-orbit. The “extra time” is off nominal for ANY space mission. There are 2 missions going on here that have to mesh. One is ISS scheduled operations and the second is the Starliner flight. Starliner got there late and the ISS schedule that has been laid out out for a long time is taking priority. There's way too much involved with spacewalks and ship undockings with respect to station preops and ground console support for the two to happen at the same time. That is what the article in OPs lame title thread is about. In the other thread there is a lot of information about the leak in the videos. I could be wrong but I haven't seen anything released about the helium leak being from tank accumulator pressure helium. Is that true and I missed it? My understanding is it is from the pneumatics/control which aren't sourced from tank accumulator pressure and the location of the leaks are at the thruster manifolds which they have been isolating when not in use. |

Quote HistoryQuoted: First 2 Starliner flights were unmanned so that shouldn't be a problem. Just detach from ISS then come back to Earth if nothing else goes wrong. Crew can come back on a Soyuz or Dragon once they have been provided with proper suits. If it detached and something else went very wrong, having an uncontrollable Starliner just orbiting up there would be pretty bad though.

https://spaceflightnow.com/2024/06/14/nasa-boeing-set-new-undocking-landing-date-for-starliner-spacecraft/
The reason for the extended stay is in part due to a need to gather more information about the Starliner capsule with the benefit of having an astronaut crew assigned to study aspects of the spacecraft with additional detail. “The crew can do more detailed testing into the various aspects of the spacecraft hardware with the additional time in orbit. It’s an opportunity that is important because the spacecraft is new and this is the first time carrying a crew that can perform this testing on-orbit,” a NASA spokesperson told Spaceflight Now. “Even though an effort is repeated, the additional work gives them a chance to refine what they saw the first time and pass more knowledge to the crews of Starliner missions to come.” Some of the work that will be done in the next several days will also be to better understand some of the anomalies that Starliner experienced during its journey to the orbiting outpost and while docked.

"The helium leak on the launch pad was not an immediate safety issue, but in investigating it further, NASA and Boeing uncovered a design vulnerability in the RCS system that could affect Starliner's reentry. Agency officials subsequently certified a new reentry mode after testing the idea on the ground in simulations with the CFT crew, veteran NASA astronauts Barry Wilmore and Suni Williams, both of whom are former U.S. Navy test pilots." Sounds like they were stranded for a bit if they couldn't safely reentry. Hopefully the new 'reentry mode' works...https://www.space.com/boeing-starliner-earth-return-delay-june-26-thruster-issues |

...they need to test the thrusters on the ground to figure out how to get the astronauts back safely...  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. |

Both before launch and before docking when they were wringing their hands deciding if they wanted to dock or rtb.  I really would love to know who pushed so hard to keep rolling the dice. NASA or Boeing? |

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. The statement above is interesting because White Sands has an altitude chamber that you can fire rocket engines in at near orbital pressures. The engines themselves have flown before on unmanned flights with no issues - if we assume the engine design is sound, then they are investigating some sort of abnormal scenario. Rampant speculation on my part, but if the helium leak was so bad that they lost significant amounts of helium then they might be worried about having enough pressure to reliably operate the engines. There is pressure drop as the helium and fuels flow through the plumbing when the engines are running. The engines run at 25bar of chamber pressure so you need more than 25bar of pressure in the fuel tanks to force the fuel into the engines. But how much more? I wonder if they ever probed the limits of just how little hydrogen pressure is needed to reliably pump fuel at the required rates into the engines. You might need 26 bar, 30 bar or 100bar in the fuel tanks to get adequate fuel flow rates. If the fuel pressure at the engine injectors is not high enough the engine will flame out and/or generate less thrust - unreliable/unpredictable thrust is an obvious safety problem. The engines could also run at an incorrect fuel/oxidizer ratio which could generate lower thrust than normal and therefore require more fuel/helium than planned. Either situation would explain the thruster problem that delayed docking, why they are doing ground tests of the engines, and the indefinite delay for the return trip. |

It has to carefully back away, lower the orbit and then conduct the reentry burns. There is a huge zone around the ISS that all craft much execute actions perfectly before they are allowed within it and they have to be functioning perfectly to be released. |

They spontaneously ignite on a catalyst and require no ignition system. Hydrazine and other such fuels are often used on earth by reacting them with ambient air. On a spacecraft you have to carry your oxidizer with you. |
