Starliner return delayed again to June 26th
In a press briefing today, Boeing and NASA announced that they have decided to delay the return of Boeing’s Starliner capsule, carrying two astronauts, another four days to June 26, 2024. The landing would take place just before dawn, landing at White Sands in New Mexico.
The decision to delay is related to the results from the hot fire tests of the aft thrusters of Starliner on June 15, 2024. Engineers want to review the data, which included finding that one of the eight thrusters is producing unacceptable results and will not be used for the rest of the flight. The other seven thrusters however produced acceptable results, “good thrust” as noted by one official.
The extra time to review the data is also because these thrusters are on the service module, which will not return to Earth. They want to make sure they understand the issues entirely. The longer time docked to ISS is also giving them better data for future longer missions.
As for the helium leaks, the level of leaking appears to be dropping, and in fact dropped after the hot fire burns, and “appears to be somehow related to the thrusters.” Either way, the safety margins remain sufficient so that the return is not threatened in any way by these leaks.
The valve issue also seems under control, with all the valves now working as expected.
Overvall, engineers have decided they have a safe vehicle that can not only be used to return to Earth as scheduled, they are confident that they could also use Starliner as a lifeboat in a sudden emergency.
