A little while ago the Progress MS-13 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 74 or 74P. In this mission, the route used is out of the ordinary since the journey will last about three days.
The Progress MS-13 cargo spacecraft is carrying a total of almost 2,500 kilograms (more than 5,500 lbs) of various types of supply including food, water, air, oxygen, propellant and more such as a series of products for the International Space Station crew, various science experiments, tools and various hardware.
In the last two resupply missions, the Russian Progress space cargo ship was launched on an ultra-fast track, which requires a very precise set of maneuvers. The Progress MS-13 spacecraft was launched the day after another cargo spacecraft, the SpaceX Dragon, and in these cases the routes are established so that the two spacecraft reach the International Space Station on different days. For this reason the Russian space agency Roscosmos didn’t use the “classic” two-day route either. The Progress MS-13’s route requires three days of journey for a total of 49 orbits, a route really out of the normal. Despite the one-day delay on the Dragon spacecraft’s launch, the Progress MS-13 will arrive the day after it.
The Progress MS-13 cargo spacecraft is scheduled to reach the International Space Station on Monday, around 10.38 UTC. The Progress has an automated docking system so it will reach the Pirs module on its own.
