"The contour of the Progress MS-21 transport cargo ship, deorbitation of which is scheduled for February 18, was depressurized, as confirmed by the telemetry data of the mission control center," the agency said in a statement.
The reasons for the depressurization are yet to be established, the statement read.
"The passage hatch of the ship is closed, thus Progress MS-21 is isolated from the general space of the ISS. The temperature regime and pressure on board the station are normal, nothing is threatening the life and health of the crew, they feel good," Roscosmos added.
All cargo scheduled for deorbitation has already been loaded onto the Progress MS-21 spacecraft, according to the statement.
