It is occurred once more. A Russian Progress cargo spacecraft docked to the Worldwide House Station has sprung a coolant leak, NASA mentioned in a press release on Saturday. That is the second incident of this kind in latest months after a Russian Soyuz spacecraft hooked up to the ISS spewed out coolant from a leak in December.
NASA mentioned “engineers on the Russian Mission Management Heart outdoors Moscow recorded a depressurization within the unpiloted Roscosmos Progress 82 cargo ship’s coolant loop, which is docked to the space-facing Poisk module on the station.” The reason for the leak is beneath investigation.
The uncrewed Progress 82 (also referred to as Progress MS-21) arrived in late October of final 12 months carrying a number of tons of meals, gasoline and provides. It is at present filled with trash for disposal and is scheduled to undock on Friday, Feb. 17, to deplete in Earth’s environment.
Most significantly, the crew — which consists of three NASA astronauts, one Japanese astronaut and three Russian cosmonauts — is protected. “The hatches between the Progress 82 and the station are open, and temperatures and pressures aboard the station are all regular,” NASA mentioned. “The crew, which was knowledgeable of the cooling loop leak, is in no hazard and persevering with with regular area station operations.”
A minimum of the Progress spacecraft is not used to hold people. NASA and Roscomos declared the leaky Soyuz MS-22 unfit to convey crew again to Earth, necessitating a brand new plan for getting NASA astronaut Frank Rubio and Russian cosmonauts Sergey Prokopyev and Dmitry Petelin again dwelling. The businesses hatched a plan to ship up a recent Soyuz in February and detach MS-22 with no crew on board.
Roscosmos and NASA suspect a micrometeorite (a tiny area rock) might have brought on the Soyuz leak. It is unknown but if the Progress drawback is perhaps traced to an analogous supply or if the leak is coming from an analogous location. A leak on a cargo craft is not as worrisome because the Soyuz leak, however the mixture of the 2 so shut collectively will seemingly set off further scrutiny of Russian spacecraft, particularly because the launch of a “substitute” Soyuz nears.
