Uncrewed Progress Spacecraft Deorbit Burn Time Set

On Feb. 17, the uncrewed Roscosmos Progress 82 cargo spacecraft undocked without issue from the International Space Station’s Poisk module at 9:26 p.m. EST. Following undocking, Expedition 68 cosmonauts Sergey Prokopyev and Dmitri Petelin sent commands from the station’s Roscosmos segment to rotate the Progress for additional visual inspections using space station’s external cameras of the general area where a coolant leak occurred on Feb. 11.

After Progress departure from the space station, flight controllers at Mission Control in Moscow canceled Friday’s scheduled deorbit burn while Roscosmos analyzed the post-undocking imagery collected of the Progress radiator.

Early Saturday, Roscosmos managers decided to deorbit Progress Saturday, Feb. 18, with a deorbit burn time of 10:15 p.m. EST. Progress remains in a stable configuration and on a safe trajectory well away from the International Space Station. Loaded with trash, Progress will deorbit over the Pacific Ocean after spending four months at the station.

Update on Progress Resupply Spacecraft Deorbit

Following the undocking of the uncrewed Roscosmos Progress 82 cargo spacecraft from the International Space Station at 9:26 p.m. EST on Friday, Feb. 17, flight controllers at Mission Control in Moscow canceled the scheduled 11:02 p.m. deorbit burn, which would have set the vehicle on course to burn up over the Pacific Ocean.

Progress 82 currently is in a stable configuration and on a safe trajectory that keeps it well away from the International Space Station while teams on the ground discuss a forward plan.

International Space Station Operations Update, Crew Continues Normal Activities

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.
