Progress MS-09 (Russian: Прогресс МC-09), identified by NASA as Progress 70P, was a Progress spaceflight operated by Roscosmos to resupply the International Space Station (ISS). This was the 161st flight of a Progress spacecraft.
The Progress-MS is an uncrewed freighter based on the Progress-M featuring improved avionics. This improved variant first launched on 21 December 2015. It has the following improvements:
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.
Progress MS-09 docked as scheduled with the nadir docking port of the Pirs module on 10 July 2018 at 01:31 UTC.
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.
The Progress MS-09 spacecraft delivered 2,450 kg of cargo and supplies to the International Space Station. The following is a breakdown of cargo bound for the ISS:
Beginning with the Progress MS-03, the Progress can optionally carry four CubeSat deployers for a total of 24 CubeSat-units.
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.
