Space Station Progress 82 Cargo Ship Experiences Coolant Loss
current ISS configuration

Earlier today, Feb. 11, the uncrewed Roscosmos Progress 83 cargo spacecraft docked automatically to the aft end of the Zvezda service module at the International Space Station. The rendezvous and docking operations were conducted with no issues.

Meanwhile, engineers at the Russian Mission Control Center outside Moscow recorded a depressurization in the unpiloted Roscosmos Progress 82 cargo ship’s coolant loop, which is docked to the space-facing Poisk module at the station. Progress 82, which arrived to the space station in October 2022, is scheduled to undock Friday, Feb. 17, filled with trash and will be deorbited over the Pacific Ocean.

The reason for the loss of coolant in the Progress 82 spacecraft is being investigated. The hatches between the Progress 82 and the station are open, and temperatures and pressures aboard the station are all normal. The crew, which was informed of the cooling loop leak, is in no danger and continuing with normal space station operations.

NASA specialists are assisting their Russian counterparts in the troubleshooting of the Progress 82 coolant leak. Officials are monitoring all International Space Station systems and are not tracking any other issues.
