by Russia’s state space corporation Roscosmos reported Saturday that the external cooling system of the Progress MS-21 cargo spacecraft aboard the International Space Station lost pressure. Roscosmos said there were no threats to the seven astronauts aboard the space station. The incident occurred shortly after another cargo spacecraft, Progressive MS-22, docked with the space station. Dmitry Strugovets, the former head of press at the Russian space agency, later clarified that all of the spacecraft’s coolant had leaked. This is the second time a Russian spacecraft has suffered a coolant leak in less than two months. On December 14 last year, its manned spacecraft Soyuz MS-22 suffered an external cooling circuit leak – the cause is believed to be hit by a micrometeorite. Last month, Roscosmos and NASA announced that they would launch another manned spacecraft, Soyuz MS-23, to replace MS-22 and pick up three astronauts back to the ground.
