Progress MS-15 has completed its mission

February 9, 2021

 Today, on February 9, 2021 at 08:21:30 Moscow time cargo transportation spacecraft Progress MS-15 undocked from the Pirs module of the International Space Station. After departing at a safe distance from the station specialists of the Lead Operational Control Team of the ISS Russian Segment started a controllable de-orbiting of the spacecraft.

According to the program loaded in the onboard computer, at 11:30:11 Moscow time the main engine fired a de-orbit burn via commands from the Mission Control Center, TsNIIMASh (part of State Corporation Roscosmos). Having operated for 3 minutes 30 seconds it fired a retro-burn of 116 meters per second to the cargo spacecraft. Thereafter Progress MS-15 descended from the earth orbit and burned up. At about 12:13 Moscow time the spacecraft fragments unburnt in the earth atmosphere submerged in a spacecraft cemetery in an non-navigational water area of the south part of the Pacific Ocean.

Russian ISS-64 Expedition crewmembers, Roscosmos cosmonauts Sergei Ryzhikov and Sergei Kud Sverchkov began to prepare for arrival of the next cargo vehicle. On February 17, 2021 the freed docking port of the Pirs docking compartment of the International Space Station shall be taken by cargo transportation spacecraft Progress MS-16, which will deliver 2.5 tons of various cargo to ensure life support of the station and the crew. At present the spacecraft is being exposed to final processing operations at the integration and test facility of the Baikonur Launch Site. Its launch from the launch facility No. 31 is scheduled for February 15.

The new cargo spacecraft shall deliver 600 kg of resupply propellant, 420 liters of Rodnik system portable water and 40.5 kg of compressed gases with additional nitrogen supplies, as well as about 1 400 kg of various equipment and materials including hardware for onboard control and life support systems, kits for space experiments, medical monitoring and sanitary and hygienic items, articles of clothing, standard food ratios and fresh products for the current Expedition crewmembers. In addition, the cargo compartment accommodates a repair and recovery assembly consisting of a set of reinforcing adhesive cover plates intended for temporary sealing of the defects detected in the hull of the transfer chamber of the ISS Zvezda Service Module.
