In a mission to resupply the International Space Station, the Russian Federal Space Agency – Roscosmos – used the Progress MS-12 uncrewed vehicle to continue testing and validating the super fast-track 2 orbit, 3-hour launch-to-docking profile for their spacecraft.
Confirmed by NASA earlier this month, this super fast-track rendezvous will eventually be employed on human launches to the international outpost beginning next year.
Launch of Progress MS-12 occurred from Site No. 31/6 at the Baikonur Cosmodrome in Kazakhstan aboard a Soyuz 2.1a rocket at 08:10:46 EDT (12:10:46 UTC) on 31 July 2019. Docking to the Station followed at 11:29 EDT (15:29 UTC).
