The section where the incident occurred was used to test experimental technologies for refueling spacecraft with methane using special techniques, including the Allow fuel conservation In long tanks in containers.
The RRM-3 module of the US section of the International Space Station has leaked several tens of kilograms of methane into space, Sputnik said. The incident was reported to have occurred after the electrical equipment of the section was broken and the cryogenic freezer system, which keeps the methane in liquid form, making it easier to curb it, stops its work.
There was no immediate danger aboard the ISS. because the module is located outside the crew rooms of the station. The shutters of the station lights were temporarily closed to prevent contamination.
The module contained about 42 kilograms of methane before the incident and served to test and determine the use of the ISS for refueling spacecraft with liquefied methane. The RRM-3 also tested the technology to store methane as a fuel for half a year without leaks in space by using a cryogenic freezer.
