As planned, the spacecraft will stay in space 265 days.

The arrived Progress delivered more than 2.5 tons of cargo and materials, i.e. propellant, water, pressurized nitrogen and various equipment such as onboard life-limited hardware, tools and accessories for extravehicular activities, cables, sensors, medical means and clothing. The spacecraft also carries Russian science experiment kits for investigating human alimentary and immune systems, impact of space flight factors on cosmonaut organism, developing new sterilizing agents, as well as studying the effect of microorganisms on materials’ strength in space.

In addition, the Progress MS accommodates two pairs of super-small spacecraft, YUZGU-55 Nos. 11 and 12, and Tsiolkovsky-Ryazan Nos.1 and 2, which Roscosmos cosmonauts will launch to orbit during their egress into space.
