  ISS resupply mission. The Progress M failed to reach orbit. Five minutes and 25 seconds into flight, during the burn of the booster's third stage, the engine's gas generator failed and the engine shut down. The upper stage and spacecraft crashed in the Gorno-Altai region of Russia. First ever failure of a Progress spacecraft to dock with a space station in its 135-mission history. The six crew aboard the ISS had sufficient supplies, but the mishap delayed the launch of the Expedition 29 replacement crew until the cause of the failure was understood and the Soyuz launch vehicle cleared again for manned launches. The return to Earth of the first half of the Expedition 28 crew has also delayed to mid-September, meaning the station would be reduced to a three-person crew for a time.
