Progress M-40 (Russian: Прогресс M-40) was a Russian unmanned Progress cargo spacecraft, which was launched in October 1998 to resupply the Mir space station, carry the Sputnik 41 satellite[4] and the unsuccessful Znamya 2.5 solar mirror.



Progress M-40 launched on 25 October 1998 from the Baikonur Cosmodrome in Kazakhstan. It used a Soyuz-U rocket.[2][5]



Progress M-40 docked with the aft port of the Kvant-1 module of Mir on 27 October 1998 at 05:34:41 UTC, and was undocked on 4 February 1999 at 09:59:32 UTC.[3][6] On 4 February 1999 at 10:24 UTC, following undocking from Mir, an unsuccessful attempt was made to deploy Znamya 2.5, a solar mirror.[3][6]



It remained in orbit until 5 February 1999, when it was deorbited. The deorbit burn occurred at 10:16:05 UTC, with the mission ending at 11:09:30 UTC.[3][6]
