Floor groups are investigating the reason for an upsetting coolant leak that erupted yesterday on the Russian Soyuz Ms-22 spacecraft docked to the Worldwide Area Station (ISS). Consultants at the moment are saying {that a} micrometeorite could have been accountable.
Micrometeorites are tiny pebbles, roughly the dimensions of a grain of sand, that zip round area at excessive speeds, often impacting spacecraft. The Webb Telescope’s major mirror was smacked by a micrometeorite earlier in May, barely impacting its efficiency. They could be small, and normally trigger no hurt, however ought to a micrometeorite handle to hit one thing like a spacecraft radiator, effectively, that has the potential to supply some badness.
Sergei Krikalev, a former cosmonaut who heads the crewed area flight program for Roscosmos, was quoted in Russian state media outlet TASS as saying that the reason for the leak “could also be a micrometeorite coming into the radiator.” A potential consequence of a collision could possibly be “adjustments within the temperature regime,” he added. “No different adjustments within the telemetric parameters of both the Soyuz spacecraft or the [ISS] on the Russian or American segments have been detected,” he mentioned.
{That a} micrometeorite struck the Soyuz radiator is a definite risk. However it’s additionally potential {that a} tiny piece of human-produced area junk is answerable for the leak. In line with the European Area Company, there are at the moment round 130 million pieces of space junk in Earth orbit that measure between 1 millimeter and 1 centimeter in measurement.
On Wednesday, ground teams discovered a fountain of particles pouring out from the docked Soyuz spacecraft. The bizarre sight, which lasted for hours, was traced to a coolant leak probably coming from the exterior radiator cooling loop of the Soyuz spacecraft, NASA wrote in a blogpost on Thursday.

The leak was first detected round 7:45 p.m. ET on December 14 when “information from a number of strain sensors within the cooling loop confirmed low readings,” the area company added.
Two Russian cosmonauts had been making ready to exit the area station for a routine spacewalk, which has now been postponed indefinitely because of the leak. Fortunately, the crew on board the ISS weren’t harmed, but it surely’s not but confirmed whether or not the Soyuz spacecraft suffered significant injury. The spacecraft carried NASA astronaut Frank Rubio and Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin to the ISS in September, and is ready to take them residence when their expedition ends within the spring of subsequent 12 months.
“Roscosmos is intently monitoring Soyuz spacecraft temperatures, which stay inside acceptable limits,” NASA wrote in its weblog. “NASA and Roscosmos proceed to coordinate exterior imagery and inspection plans to help in evaluating the exterior leak location.”
The area companies may also be utilizing Canadarm2, a robotic arm put in on the surface of the ISS, to get a more in-depth have a look at the Soyuz spacecraft. Canadarm2 was struck by a flying piece of area junk, or presumably a micrometeorite, in June 2021, which created a hole on the robotic arm.
If floor groups deem the Soyuz spacecraft unusable for a crewed journey again to Earth, then the three astronauts on board the ISS might have to attend for an additional spacecraft to make its method to low Earth orbit and transport them again residence.
We’ll be following the story because it develops and offering updates on the leaky spacecraft.
