Update, September 15, 11:30 pm ET:  NASA still has not posted any updated information about this launch. Whether that means it’s not taking place tomorrow morning EDT, or NASA’s not covering it (which would be unusual), or it wasn’t posted on NASA Live, is a mystery.  Check NASA Live for updates.

Update, September 7, 11:55 am ET: Reports on X by @RussianSpaceWeb and @katlinegrey today say the launch has been postponed because of problems with the Soyuz rocket’s third stage. No official announcement has been made yet, however.

Original Entry: Russia will launch the next Progress cargo mission to the International Space Station, Progress MS-35, on September 9, 2026 from the Baikonur Cosmodrome in Kazakhstan. NASA refers to this as Progress 96 (96P) because it is the 96th Progress to resupply the ISS, although there were many dozens launched before that to support Soviet/Russian space stations starting in 1978.

NASA typically provides live launch and docking coverage. Check NASA Live for details.
