A next Russian spacecraft docked at the ISS is leaking coolant

Leakage Detected in 2nd Russian Craft Docking at ISS

A second Russian spacecraft, launched to the Global Area Station (ISS) on April 9, has commenced leaking coolant from a person of its units. This is the initially time given that the start of the lunar orbital station ‘Lunar Gateway‘ previous wintertime that a leak has been detected in a spacecraft related to the ISS.

Result in of the Leak

The induce of the leakage is thought to be the deterioration of a rubber seal that protects the cooling process of the spacecraft’s thrusters. This is a variety of mixture seal, developed to shield the thrusters from equally air and h2o, although even now enabling essential lubrication. Given that the thrusters want to stay in frequent neat temperatures, it is essential that the seals do not wear out or turn into brittle.

Repercussions of the Leak

Whilst the leak is not considered to be serious, it is continue to a induce for worry because of to the potential risks that arrive with extended duration spaceflight. As the spacecraft is in a reduced Earth orbit it will not be ready to be fixed. It is anticipated that the leakage will lead to the cooling program to eventually fall short, ensuing in the heating up of the thrusters. This could direct to a far more severe malfunction of the spacecraft, which could place the crew aboard the ISS in danger.

Steps Remaining Taken to Resolve the Leakage

To overcome the leak, the crew on the ISS has been instructed to:

  • Just take the necessary actions to cut down the level of the leakage, this sort of as replacing the seal
  • Keep an eye on and modify the cooling system as essential
  • Report back to ground command if the leakage price boosts or other challenges occur

At this time, the spacecraft is still working and the crew is safe, although they stay on warn.


It is still unsure how the leak will impact the procedure of the spacecraft and the ISS in the very long-phrase. In the meantime, the ISS crew is getting all safety measures important to make sure that the second Russian spacecraft will continue to be leak-totally free and intact. Must anything at all adjust, they will report again to ground control accordingly.
