Astronauts Christopher Cassidy and Thomas Mashburn successfully repaired International Space Station (ISS), eliminating the leakage of ammonia from the refrigeration system. Thus, ammonia snowfall in space has been discontinued.
According to NASA, Cassidy and Mashburn spent in space five o’clock thirty minutes. During this time they disconnected the unit pumps the cooling system and replaced it with a spare. After that, the mission control center in Houston, including the pump, and the astronauts were watching him, watching, will continue to leak. While the new ammonia flakes were found, but the observations will continue to finally make sure that the problem is fixed.
leakage of ammonia, which is used in the cooling system, was recorded on 9 May, when the astronauts saw snowflakes drifting in space. Heavy snow has caused damage to the cooling system of one of the solar panels in the U.S. section of P6. If the problem persists, then the crew would have 48 hours to switch to the backup cooling system. Since the leak occurred in the U.S. segment of the station, the astronauts were engaged in a fix NASA, who made an unscheduled spacewalk.
“Yes, indeed, there was a leak of ammonia, it was in the U.S. segment of the station, but it is not critical. Such a situation (ammonia slip) is not happening for the first time, unfortunately. Meanwhile, the Russian segment of the station and all the rest of it are working in normal mode, “- commented on the incident head of Roskosmos space programs Alexei Krasnov. Previous leaked mentioned by Krasnov, took place in November last year in the cooling system of the same solar cell.
Recall of the ISS is now a crew of six people: the Canadian astronaut Chris Hadfield (commander), Roman Romanenko, Thomas Mashburn (NASA), Pavel Vinogradov, Alexander Misurkin and Christopher Cassidy (NASA) . Hadfield was soon to pass the post Vinogradov, who will be in command of the 36th expedition to the ISS.
