Progress M1-1
[1] It was the first flight of the Progress-M1, a derivative of the Progress-M originally designed for resupplying the International Space Station, which was optimised for the transportation of fuel over pressurised cargo.Progress M1-1 was launched by a Soyuz-U carrier rocket from Site 1/5 at the Baikonur Cosmodrome.[2][4] It was deorbited at 19:26:03 GMT,[2] and burned up in the atmosphere over the Pacific Ocean around fifty minutes later.[5] Progress M1-1 was used to reboost Mir, which was rapidly decaying from orbit at the time of its arrival.It carried nitrogen to repressurise the station following a leak, as well as supplies for the EO-28 crew, who arrived aboard Mir in April.
