NASA is monitoring a leak on the Russian module of the Worldwide House Station (ISS), from which air has been escaping at an growing fee for practically 4 years. The area company acknowledged that the leak is rising, whereas claiming it poses no menace to the astronauts on board.
The speed at which air is leaking within the Zvezda service module has doubled from one pound a day to “a bit of over two kilos a day,” NASA ISS Program Supervisor Joel Montalbano revealed throughout a press briefing on Wednesday, based on SpacePolicyOnline.
The Roscosmos area company first reported the leak in August 2020, which was discovered within the Russian Zvezda life assist module that Russia launched to low Earth orbit in July 2000. The leak is in a vestibule (named Prk) positioned between the docking port and the remainder of the module. The module comprises essential life assist programs, and crews depend on it as a essential assist hub in emergencies.
The speed of leakage elevated round per week earlier than the February 14 launch of the Progress MS-26 cargo spacecraft, which docked to the aft finish of Zvezda. The hatch that connects the module to the ISS remained open for 5 days because the crew offloaded the cargo from Progress MS-26 onto the area station, but it surely has since been closed shut.
In an announcement launched on Wednesday, Roscosmos additionally acknowledged the air leak, including that its crew are often working to establish the supply and repair doable leaks on the ISS, based on Russian state media TASS. The area company added that the leak poses no menace to the crew or the area station itself.
NASA additionally harassed that the crew and the area station are protected for now. “The groups are watching it. We’re working with our Russian colleagues on the subsequent step,” Montalbano stated throughout Wednesday’s briefing, SpaceNews reported. “It’s not an influence to crew security or car operations.”
This isn’t the one leak detected from Russian {hardware} on the ISS. In December 2022, floor groups noticed a fountain of particles pouring out from a Soyuz spacecraft docked to the ISS. In February 2023, shortly after docking with the ISS, a Russian Progress 82 freighter also started leaking coolant. In October 2023, the backup radiator of Russia’s Nauka module, mounted on the module’s exterior, started leaking coolant. Russia blamed the leaks on exterior impacts, however the three consecutive incidents instructed potential manufacturing defects.
The ISS has been in low Earth orbit for greater than 20 years, housing crews of astronauts conducting analysis within the microgravity surroundings. In 2030, the area station is because of retire, deorbiting its historical {hardware} to make room for newer, business area stations. Till that occurs, hopefully the ageing area station can preserve it collectively for the crew on board.
