Progress spacecraft suffers coolant leak

For the second time in less than two months, a Russian spacecraft docked to the International Space Station suffered a coolant leak. The Russian space agency Roscosmos reported a depressurization in the coolant loop of the Progress MS-21 cargo spacecraft Feb. 11, shortly after the docking of another cargo spacecraft, Progress MS-22. Roscosmos and NASA said that controllers were investigating the problem and that it did not affect other station systems. The Soyuz MS-22 spacecraft docked to the station also experienced a coolant leak in December, an event Roscosmos blamed on a micrometeoroid hit. Progress MS-21 remains scheduled to undock from the station late this week to burn up in the atmosphere.
