Description : An improved version of cargo freighters used to supply the Mir space station, the Progress M series had greater cargo capacity, a modernized approach/docking system and carried 2 solar panels to generate electrical power. Progress M can fly for 30 days independently and 108 days docked with Mir. Spare propellent in Progress M’s tanks can be transferred to Mir before it is consigned to burn up in reentry. In the past, extra fuel was abandoned with the craft. Future Progress vehicles will carry a recoverable reentry capsule for the speedy return of up to 150 kg of material from Mir to earth.


Progress M-25 was launched from the Baykonur Cosmodrome by a Soyuz-U rocket. The cargo ship carried more than 2 tons of supplies and a returnable Raduga capsule to bring back about 150 kg of experimental results from Mir.
