A robotic Russian Progress cargo spacecraft launched toward the International Space Station tonight (Aug. 22), carrying 3 tons of supplies toward the orbiting lab.
If all goes according to plan, the freighter will arrive at the orbiting lab on Thursday (Aug. 24) at 11:50 p.m. EDT (0350 GMT on Aug. 25). You can watch the rendezvous and docking here on Space.com when the time comes.
Progress 85's launch comes just a few days after the departure of a previous Russian cargo vehicle from the International Space Station.
Progress 83 left the ISS on Sunday (Aug. 20) after a six-month stay, to be deorbited over the open ocean. (This is normal for Progress vehicles; unlike SpaceX's Dragon capsules, Progress freighters aren't designed for recovery and reuse.)
There's still another Progress docked to the ISS — Progress 84, which arrived at the orbiting lab in late May.
And yet another spacecraft will head to the orbiting lab soon. SpaceX's Crew Dragon capsule Endurance is scheduled to launch early Friday morning (Aug. 25), carrying four astronauts to the ISS on the Crew-7 mission.
