Progress MS-09 docks to ISS, completing fast-track orbital rendezvous

A Russian cargo vessel took just three hours and 40 minutes to reach the International Space Station on Tuesday, Roscosmos space agency said, smashing the record flight time by two hours.

A Soyuz rocket is scheduled to launch the uncrewed Progress 70 spacecraft from the Baikonur Cosmodrome in Kazakhstan at 5:51 p.m. EDT (2151 GMT) to deliver almost 3 tons of supplies for the space station's crew.

The spacecraft is expected to dock at the space station at 9:39 p.m. ET. The fastest-ever cargo run took less than four hours, rather than the usual two days, due to a carefully planned, time-saving, two-orbit trajectory that Russian Federation wants to use for crewed as well as uncrewed flights.

This is the spacecraft's first attempt of a fast-track orbital rendezvous with ISS.

Russian cosmonauts Oleg Artemyev and Sergey Prokopyev were on board the station and ready to take over manual control of the craft should any problems occur, but the docking proceeded in a fully automatic mode.

The Progress MS-09 or Progress 70 cargo ship-the former name is used by the Russian space agency, Roscosmos, and the latter by NASA-only did two orbits of Earth before docking with the ISS.
