Successful treatment of leakage of ammonia gas on ISS station

The US Aeronautics and Space Administration (NASA) said on May 11 that two astronauts on the International Space Station (ISS) had finished their walk out of space for more than 3 hours, completing the mission. case of ammonia gas leak treatment. This gas is used for cooling solar panels - the power supply for ISS.

NASA said that for a year now, ISS astronauts have been concerned about the phenomenon of ammonia gas leakage, but then the gas loss is only about 2kg / year.

The two astronauts Chris Cassidy and Tom Marshburn on the ISS Station have concluded
End the walk out of space to handle ammonia gas leak.

From May 9, the amount of ammonia leaking suddenly increased, on average, every day solar system insulated systems lost nearly 2kg of ammonia gas.

The two astronauts Chris Cassidy and Tom Marshburn have a duty to find the cause to overcome. They said a meteorite or some fragment traveling through the universe could have collided with the radiator of the energy battery's insulation system, and could have been located right in the ammonia gas pump. so they replaced the pump.

Ammonia is used in the refrigeration system of the power supply unit for ISS. Each ISS solar panel has its own cooling system. There are 8 battery panels on the station with 4 power conversion clusters weighing 100kg. This is the main power supply for the whole station.

Restoring the energy sources provided to ISS helps the crew not to interrupt unnecessary equipment, allowing ISS to operate at 100% of the design capacity.

Cassidy and Marshburn are all experienced astronauts operating in space. This is their third walk out of the air, the most recent trip was done in November last year.
