A little while ago, Northrop Grumman’s Cygnus spacecraft blasted off atop an Antares rocket from the Mid-Atlantic Regional Spaceport (MARS), part of NASA’s Wallops Flight Facility (WFF) on Wallops Island. After about nine minutes it successfully separated from the rocket’s last stage went en route to its destination. This is its 15th official mission, called NG-15 or CRS NG-15, to transport supplies to the International Space Station for NASA.
A few hours ago, the Progress MS-16 spacecraft blasted off atop a Soyuz-2.1a rocket from the Baikonur Cosmodrome in Kazakhstan. After about nine minutes it successfully separated from the rocket’s last stage and was placed on its route. The cargo spacecraft began its resupply mission to the International Space Station also called Progress 77 or 77P. In this mission, the route used is the one that requires about two days.
It was afternoon in the USA when SpaceX conducted in Boca Chica, Texas, the flight test of the Starship prototype identified as SN9, the second after the one conducted on December 9, 2020. SN9 was supposed to solve the problems of the previous prototype and it too carried out regularly its flight up to an altitude of about 10 kilometers and then attempted a controlled landing at the end of a series of maneuvers. After 6 minutes and 26 seconds of flight, like its predecessor, SN9 landed too fast and was destroyed as a result. SpaceX confirmed that its good results with regards to Starship’s maneuverability, but landing is still an issue. With the many first-stage landings of the Falcon 9 rocket, it’s making that kind of maneuver look easy, but it requires perfect systems tuning.
It was afternoon in the USA when SpaceX conducted the first flight test of a prototype of Starship, the one identified as SN8, in Boca Chica, Texas. Equipped with 3 Raptor engines, SN8 flew regularly up to an altitude of approximately 12.5 kilometers, then attempted a controlled landing at the end of a series of maneuvers. During the ascent it remained in a vertical position while during the descent it carried out various maneuvers that brought it to a horizontal position almost to the ground, where it turned over. However, after 6 minutes and 42 seconds of flight, SN8 landed too fast and was consequently destroyed. Despite the ending, the test was in many ways really positive.
A little while ago the SpaceX Dragon 2 spacecraft blasted off atop a Falcon 9 rocket from Cape Canaveral in its CRS-21 (Cargo Resupply Service 21) mission, also referred to as SPX-21. After just over eleven minutes it separated successfully from the rocket’s last stage and went en route. This is the 21st mission for the Dragon spacecraft to resupply the International Space Station with various cargoes and then return to Earth, again with various cargoes. It’s the first mission for this Dragon version.
