ISS air leak stopped but cause of malfunction remains unknown
The air leak at the International Space Station's Russian segment has been halted, but the cause of the cracks remains unknown. The issue was observed in the "Zvezda" module, and Russian cosmonauts managed to stop the air loss by applying a sealing compound. Experts from NASA and Roscosmos have differing views on the potential risks associated with the cracks, with possibilities including material fatigue from pump vibrations and corrosion. A final decision regarding the station's future is expected by the end of 2026, with NASA planning to conclude its use by 2030, although an extension to 2032 is being considered.
Air leaks in the Russian segment of the International Space Station, which have concerned engineers for several years, have been stopped. However, the cause of the cracks remains unknown. Ixbt.com reports on this.
The problem was observed in the transfer tunnel of the "Zvezda" module. Air loss stopped after Russian cosmonauts applied a sealant.
NASA and "Roskosmos" specialists have different views on the risk of the cracks. Among the main versions, material fatigue due to pump vibrations and corrosion are being considered.
NASA representative Joel Montalbano emphasized that he is still concerned about the condition of the station's structure. For safety purposes, the hatch between the compartments is kept closed while the crew is working.
A final decision on the fate of the station must be made by the end of 2026. NASA plans to end the use of the station in 2030, but the possibility of extending the period until 2032 is also being studied.
