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 and the unsuccessful Znamya 2.5 solar mirror.

Launch

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

Docking

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. 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.
