A few hours ago, the Progress MS-23 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 ultra-fast track in its resupply mission to the International Space Station also called Progress 84 or 84P. After almost 3.5 hours it reached the International Space Station docking with its Poisk module. The ultra-fast track requires very precise maneuvering and a favorable position of the Station. For this reason, it wasn’t used in the previous two Russian resupply missions.
