Russian cosmonauts Oleg Kononenko and Nikolai Chub went to space; They closed the radiator-heat exchanger circuits of the multi-purpose laboratory module (MLM) “Nauka”. On October 9, a coolant leak occurred from the MLM. This information reported In the publication of Roscosmos.
Cosmonauts Kononenko and Chub separated the radiator hydraulic circuits from the module circuits, examined the leak site and took photographs. The resulting data will be analyzed by experts on Earth to determine the causes of depressurization. The astronauts are about 25 to 30 minutes ahead of schedule, according to a representative at NASA’s Mission Control Center in Houston.
Kononenko and Chub will then need to install a small-sized radar to observe the Earth’s surface on the Nauka MLM. They will also launch the Parus nanosatellite from the surface of the module. This nanosatellite was made by MSTU students. It was designed to test Bauman solar sail technology. If they have time, the cosmonauts will also replace the retaining plates that hold the cables in place in the Zvezda module.
Russian scientists before was created Vodka-powered space engines.
