The Russian space agency Roscosmos launched a robotic cargo ship early Wednesday (Feb. 22) on a mission to deliver fresh supplies to the International Space Station.
The autonomous Progress 66 resupply ship launched into orbit atop a Soyuz rocket at 12:58 a.m. EST (0558 GMT), lifting off from a pad at the Baikonur Cosmodrome in Kazakhstan. The cargo ship will arrive at the space station early Friday (Feb. 24).
"Liftoff of the 66th Progress resupply vehicle outbound to the International Space Station," NASA spokesman Rob Navias said during live commentary.
The new spacecraft is due to dock itself at the station on Friday at 3:34 a.m. EST (0834 GMT). You can watch the Progress 66 docking live online, courtesy of NASA TV, beginning at 2:45 a.m. EST (0745 GMT).
Progress 66 is Russia's first resupply mission to the space station since the loss of the Progress 65 cargo ship shortly after its launch on Dec. 1, 2016.
Wednesday's launch occurred just hours before another cargo ship, a SpaceX Dragon capsule, was due to arrive at the International Space Station. But the Dragon aborted its approach at a range of seven-tenths of a mile due to an incorrect value in the global positioning system software used to pinpoint the spacecraft's position relative to the space station, NASA officials said.
The Dragon capsule will attempt another rendezvous on Thursday (Feb. 23), NASA officials added.
The International Space Station is currently stocked with supplies using a fleet of robotic spacecraft. In addition to Russia's Progress vehicles and SpaceX's Dragon capsules, the station is also resupplied by Orbital ATK's Cygnus spacecraft and Japan's H-2 Transfer Vehicles. SpaceX's Dragon and Orbital ATK's Cygnus are privately built spacecraft that resupply the space station under contracts with NASA.
