Starliner To Remain Docked To ISS With No New Departure Date

While NASA engineers review propulsion system data, Boeing's Starliner will remain docked at the ISS longer than planned, with a new departure date yet to be specified due to upcoming spacewalks and ongoing engineering reviews. "After repeated delays, the spacecraft was set to leave the outpost on June 25 and land at White Sands, New Mexico," notes The Register. NASA has stated that the crew is not in a hurry to leave, with sufficient supplies available, and the delay will allow more time to address helium leaks and thruster issues observed during docking. From the report: The Starliner will need to depart the ISS before August without some additional engineering analysis. During the post-docking news conference, Steve Stich, NASA's Commercial Crew Program manager, gave a figure of 45 days for the docked duration, meaning a docking would have to occur during the latter half of July at the very latest. The delay will remove any potential conflict with the upcoming spacewalks and give engineers more time to review data from the Starliner's propulsion system. The vehicle has been bedeviled by helium leaks and thruster problems. Once the Starliner commences its return to Earth, the service module where the problematic hardware is located will be discarded, depriving engineers of an avenue of investigation. Stich said, "We are taking our time and following our standard mission management team process. We are letting the data drive our decision-making relative to managing the small helium system leaks and thruster performance we observed during rendezvous and docking. Additionally, given the duration of the mission, it is appropriate for us to complete an agency-level review, similar to what was done ahead of NASA's SpaceX Demo-2 return after two months on orbit, to document the agency's formal acceptance on proceeding as planned." The Starliner has been cleared for use as a return vehicle in the event of an emergency. In the highly unlikely event that NASA opts not to use the Starliner as a crew return vehicle, the agency has a few options open to it. One could be to remove two crew members from the next Crew Dragon launch -- currently set for the latter half of August -- or use an upcoming Soyuz, although the latter requires custom seat liners for the crew. During the June 18 teleconference Stich confirmed that the team had already cleared the vehicle for a contingency or emergency return, and added "I think we will work through each of these issues and we will get to a point where we can bring Butch and Suni back in Starliner."

As leaks on the space station worsen, there’s no clear plan to deal with them

NASA and the Russian space agency, Roscosmos, still have not solved a long-running and worsening problem with leaks on the International Space Station.

The microscopic structural cracks are located inside the small PrK module on the Russian segment of the space station, which lies between a Progress spacecraft airlock and the Zvezda module. After the leak rate doubled early this year during a two-week period, the Russians experimented with keeping the hatch leading to the PrK module closed intermittently and performed other investigations. But none of these measures taken during the spring worked.

"Following leak troubleshooting activities in April of 2024, Roscosmos has elected to keep the hatch between Zvezda and Progress closed when it is not needed for cargo operations," a NASA spokesperson told Ars. "Roscosmos continues to limit operations in the area and, when required for use, implements measures to minimize the risk to the International Space Station."
