Soyuz carries Progress MS-17 freighter toward the ISS

A Russian Soyuz 2.1a rocket has successfully launched the Russian uncrewed Progress MS-17 space freighter into a low Earth orbit and toward the International Space Station (ISS).

The three-stage, liquid-fueled, medium-lift launch vehicle blasted off from Site 31 at the Baikonur Cosmodrome in Kazakhstan on June 29, 2021 at 23:27 UTC / June 30 at 04:27 QYZT (local time).

After 118 second of flight, the four strap-on boosters, referred to as Block B, W, D and G, shut down and separated from the Block A stage. Block A continued to burn until T+287 s before also shutting down and separating from the rocket’s third stage, the Block I. After another 238 seconds, the powered phase of the flight was complete and the Progress spacecraft separated from the Block I. This was shortly followed by the deployment of the two solar arrays and several antennas.

Progress MS-17 is now traveling through Earth’s orbit for around two days, slowly adjusting its orbit prior to the rendezvous with the space station. The spacecraft is expected to arrive at the orbital laboratory after 34 orbits around the planet, on Friday, June 2 and dock to the space-facing docking port of the ISS’ Poisk module at 01:02 UTC Friday morning.

Progress MS-17 carries about three tons of cargo to humanity’s orbital outpost, including 470 kg / 1,036 lbs. of propellant, 420 l of water, 40 kg / 88 lbs. of oxygen and breathing air, as well as 1,509 kg / 3,327 lbs of crew supplies and food.

The freighter will stay docked to the International Space Station for almost five months until November 2021. After unpacking of all the cargo from the Progress, the astronauts and cosmonauts onboard the space station will start loading trash into the spacecraft. Progress MS-17, as well as its “new cargo” will burn up in Earth’s atmosphere during re-entry in November.
