Progress MS-09 (Russian: Прогресс МC-09), identified by NASA as Progress 70P, was a Progress spacecraft used by Roscosmos to resupply the International Space Station (ISS). This is the 161st flight of a Progress spacecraft.
Progress MS-09 launched on 9 July 2018 from the Baikonur Cosmodrome in Kazakhstan. It used a Soyuz-2.1a rocket. NASA confirmed on 28 June 2018 that if Progress MS-09 launches on 9 July 2018, the mission succeeded a super fast-tracked rendezvous with the Station, docking to the ISS just 3 hours (2 orbits) after launch - making it the fastest orbital rendezvous ever-attempted with the International Space Station.
The new version features the upgraded Kurs-NA rendezvous system, featuring the AO-753A antenna replaced the earlier 2AO-VKA antenna and three AKR-VKA antennas, while two older 2ASF-M-VKA antennas are retained. Kurs-NA will increase the reliability and safety during docking operations. The new SUD flight control system allows for autonomous trajectory measurements using the GLONASS (Uragan) navigation satellites. The communications system is also upgraded to use the Luch-5 data relay satellites. Also improvements were made to the micrometeoroid protection, the lighting system and the docking port.
Undocking occurred on 25 January 2019, at 12:55 UTC. Later that day, the spacecraft burned up in the atmosphere and its debris fell into the Pacific Ocean.
