NASA Eyes Shorter ISS Stays Amid Busy Schedule

NASA intends to maintain its practice of exchanging International Space Station crews approximately every six months. The upcoming SpaceX Crew-13 mission is now slated for launch in mid-September, an adjustment aimed at optimizing the station's use before its planned retirement at the end of this decade.

This decision follows considerations for extending missions to eight months, which would reduce the number of flights. While some missions, like Crew-12, will experience slight duration changes, the six-month cadence remains the agency's target. Roscosmos has already transitioned to eight-month missions for its Soyuz spacecraft.

Upcoming ISS activities include several cargo Dragon and Progress launches, as well as a Northrop Grumman Cygnus mission. Notably absent from the immediate schedule is Boeing's CST-100 Starliner. A planned cargo-only test flight, Starliner-1, is delayed due to technical issues stemming from a previous crewed test flight, with its launch contingent on the completion of investigations and corrective actions.
