Progress M1-11

Progress M1-11, identified by NASA as Progress 13P, was a Progress spacecraft used to resupply the International Space Station. It was a Progress-M1 11F615A55 spacecraft, with the serial number 260.

Launch
Progress M1-11 was launched by a Soyuz-U carrier rocket from Site 1/5 at the Baikonur Cosmodrome. Launch occurred at 11:58:08 UTC on 29 January 2004.

Docking
The spacecraft docked with the aft port of the Zvezda module at 13:13:11 UTC on 31 January 2004. It remained docked for 114 days before undocking at 09:19:29 UTC on 24 May 2004 to make way for Progress M-49. Following undocking, it remained in orbit for ten days, conducting tests of its attitude control system. It was deorbited at 09:50 UTC on 3 June 2004. The spacecraft burned up in the atmosphere over the Pacific Ocean, with any remaining debris landing in the ocean at around 10:36:25 UTC.

Progress M1-11 carried supplies to the International Space Station, including food, water and oxygen for the crew and equipment for conducting scientific research. Its cargo included an Orlan spacesuit, a replacement flex hose for the Destiny module, a new Elektron oxygen generator with spare parts for the Elektron already aboard the ISS, some oxygen generator candles, spare batteries, new fire detection and suppression systems, a gas analysis system, cameras, data cassettes, and an external experiment package for the Zvezda module, Matreshka. It was also used to perform a reboost manoeuvre shortly before its departure from the ISS.

It was the last Progress-M1 11F615A55 to be launched, with all subsequent flights until 2011 using the earlier Progress-M spacecraft. An updated Progress M1, serial number 11F615A70, was later canceled. Progress-M was eventually replaced by 11F615A60, which retained the Progress-M designation, beginning with Progress M-01M in 2008.
