Russia’s robotic Progress 80 cargo ship blasted off Monday (Feb. 14), carrying about 3 tons of supplies and equipment toward the orbiting lab.
A Russian Soyuz rocket launched Progress 80 from Baikonur Cosmodrome in Kazakhstan at 11:25 p.m. EST Monday (0425 GMT or 9:25 a.m. local time on Tuesday, Feb. 15).
The freighter will orbit Earth more than 30 times before arriving at the International Space Station, a milestone that’s scheduled to occur early Thursday (Feb. 17). NASA TV will air live coverage of the cargo ship’s arrival beginning at 1:30 a.m. EST (0630 GMT) Thursday, and the Progress should link up with the Russian Poisk docking module at 2:06 a.m. EST (0806 GMT).
NASA stated that Progress 80 will carry about three tons of food, fuel and supplies to the International Space Station and that the cargo craft’s departure date from the orbiting lab will be determined by Russia’s federal space agency, Roscosmos, at a later date.
Roscosmos announced days ago that it plans to shorten Progress deliveries to a single-orbit, two-hour journey to the orbiting lab. Should early testing go to plan, implementation of that superfast route is expected in 2023.
Starting in 2018, many Progress vehicles were able to get to the station in just two orbits, or three hours. But the timing of launches and space station arrivals is subject to many factors, such as the activities of other spacecraft docked to the space station.
Progress is the main spacecraft by which Russia delivers supplies to its crews on the International Space Station, following the work of previous Progress variants that supplied earlier stations such as Salyut 6 and Mir. Progress was first developed in the 1970s under the now-defunct Soviet Union.
