, was used for the docking. Progress M1-4 remained docked for two weeks before undocking at 16:22:52 UTC on 1 December.

Second docking

Following its undocking, Progress M1-4 spent 25 days in free flight, prior to redocking with the same port on 26 December at 11:03:13 UTC. Like the original docking, the TORU system was used, as although the fault with the Kurs system had been resolved, the procedure used to abort the original Kurs docking attempt was irreversible due to the retraction of an antenna that could not be redeployed. It remained docked for 44 days before undocking again at 11:26:04 UTC on 8 February 2001. It was deorbited at 12:59 UTC on the same day. The spacecraft burned up in the atmosphere over the

Progress M1-4 carried supplies to the International Space Station, including food, water and oxygen for the crew and equipment for conducting scientific research. It was the first Progress spacecraft to resupply an Expedition crew aboard the ISS. Progress M1-4 was the first Progress spacecraft to make two dockings with the ISS, a feat that was not repeated until Progress M-15M in 2012.
