Progress M-20M (Russian: Прогресс М-20М), identified by NASA as Progress 52 or 52P, is a Progress spacecraft used by Roskosmos to resupply the International Space Station (ISS) during 2013.[3] Progress M-20M was built by RKK Energia. Progress M-20M was launched on a 6-hours rendezvous profile towards the ISS. The 20th Progress-M 11F615A60 spacecraft to be launched, it had the serial number 420 and was built by RKK Energia.


The spacecraft was launched on 27 July 2013 at 20:45 GMT from the Baikonur Cosmodrome in Kazakhstan.[4] The launch was the first out of Baikonur since a disastrous Proton-M failure on July 2.


Progress M-20M docked with the Pirs docking compartment on 28 July at 02:26 GMT, less than six hours after launch.[5]


Some last minute items were added to the Progress to assist the station astronauts with figuring out why the cooling system on one of the U.S. spacesuits sprung a leak and caused a spacewalk to be aborted the previous week.
