A brand new Russian Progress cargo ship launched into orbit Sunday night time (Feb. 14) to ship cargo to the seven crew members on the Worldwide House Station.
Russia’s house company Roscosmos launched the Progress MS-16 cargo ship, additionally referred to as Progress 77, on a Soyuz rocket from Website 31 of the Baikonur Cosmodrome in Kazakhstan at 11:45 p.m. EST (0445 GMT on Feb. 15, 10:45:06 a.m. Baikonur time). It can arrive on the station on Tuesday.
Progress 77 is carrying roughly 5,424 lbs. (2,460 kg) of cargo and provides for the crew at the moment on board the station. That features 3,086 lbs.(1,400 kg) of analysis and crew provides (like meals and clothes), together with a provide of contemporary water, nitrogen fuel and propellant for the station’s Zvezda service module propulsion system.

Tucked contained in the payload fairing of its Soyuz 2.1a launcher, the Progress MS-16 spacecraft rolled to the launch pad on Friday (Feb. 12), forward of its deliberate Sunday launch. This fashion floor crews might end their remaining flight preparations.
The Soyuz is a 152-foot-tall (46-meters) three-stage launch car. It was anticipated to go on a northeasterly trajectory after launch, jettisoning its 4 strap-on boosters roughly two minutes after liftoff. The rocket’s second stage, (additionally referred to as the core stage) is powered by one RD-108A engine designed to proceed firing for roughly three extra minutes earlier than handing the reins over to the rocket’s third stage — an RD-0110 engine.
As soon as the rocket reached a sure altitude, the fairings fell away to reveal the Progress MS-16 spacecraft, which separated from the booster’s higher stage 9 minutes into the flight to make its technique to the house station.
After separation, the Progress spacecraft ought to unfurl its photo voltaic arrays and navigation antennas. It can then align itself with the house station and put together for docking with the Russian-built Pirs module Tuesday (Feb. 16) at 1:20 a.m. EST (0620 GMT).
The Pirs module is a docking port on the Zvezda service module that doubles as an airlock for station crewmembers to make use of when conducting Russian-led spacewalks. Pirs is scheduled to be eliminated when the Progress 77 spacecraft ends its mission in July.
Instead, Roscosmos will carry up a long-awaited new addition: the Nauka laboratory. This may mark the biggest addition to the Russian phase of the house station because the Zvezda module was put in in 2000. (There’s one other, related port to Pirs, referred to as Poisk, that can stay on station.)
The Progress spacecraft is an uncrewed freighter that appears similar to its crew-toting counterpart, the Soyuz spacecraft, which is used to ferry astronauts to and from the house station. The primary distinction is that Progress is used to fly cargo and can be designed to dissipate because it re-enters Earth’s ambiance, whereas Soyuz will land again on land.
As a result of Progress autos are disposable, they’re sometimes loaded with trash and different objects to be discarded earlier than setting off on a course to dissipate within the Earth’s ambiance, sometimes over a distant area of the Pacific Ocean.
Progress 77 is the primary of two deliberate cargo deliveries to the house station inside every week. On Saturday (Feb. 20), a U.S.-built Cygnus spacecraft is slated to launch from Wallops Flight Facility in Virginia by itself two-day journey to the house station.
