Progress M-26M (Russian: Прогресс М-26М), identified by NASA as Progress 58 or 58P, is a Progress spacecraft used by Roskosmos to resupply the International Space Station (ISS) during 2015.^[3] Progress M-26M was launched on a 6-hours rendezvous profile towards the ISS. The 26th Progress-M 11F615A60 spacecraft to be launched, it had the serial number 425 and was built by RKK Energia.

Launch

The spacecraft was launched on 17 February 2015 at 11:00 GMT from the Baikonur Cosmodrome in Kazakhstan.^[4]

Docking

Progress M-26M docked with the Zvezda service module on 17 February 2015 at 16:57 GMT, less than six hours after launch.

In May 2015 Progress was used to reboost the station. First try was automatically aborted by the craft one second into the burn. Russian flight controllers identified problem into one of its eight thrusters. Second try with seven thrusters succeeded lasting 32 minutes and 3 seconds.^[5]

Cargo

The Progress spacecraft carries 2370 kg of cargo and supplies to the International Space Station.^[6]

The craft delivered food, fuel and supplies, including 435 kg of propellant, 50 kg of oxygen, 420 kg of water, and 1465 kg of spare parts, supplies and experiment hardware for the six members of the Expedition 42 crew. Progress M-26M is scheduled to remain docked to Zvezda for six months.
