The RESURS-P1 satellite tv for pc is splitting into almost 200 items, including to the harmful quantity of particles already in house.
A defunct Russian satellite tv for pc broke up into almost 200 items of particles, forcing astronauts on the Worldwide Area Station (ISS) to take shelter for about an hour.
NASA, the US house company, was knowledgeable that the Russian Earth remark satellite tv for pc RESURS-P1 had break up on Wednesday, and ordered the six US crew members on the house station to “search shelter of their respective spacecraft as an ordinary precaution,” the ISS mentioned in a message on X.
“Mission Management continued to watch the particles path and after roughly one hour the crew was cleared to evacuate their spacecraft and the house station resumed regular operations,” the corporate mentioned Thursday.
The US Area Command, which coordinates space-related operations for all branches of the armed forces, initially tracked “greater than 100 items of traceable particles” from the satellite tv for pc, which was declared useless by Russia in 2022, and reported that the incident posed “no speedy menace” .
On Thursday afternoon, the American house monitoring firm LeoLabs reported that its radars had detected not less than 180 items. “As a result of low orbit of this particles cloud, we estimate it is going to take weeks to months for the hazard to go,” the report mentioned.

The Russian house company Roscosmos retired RESURS-P1 in 2021 on account of malfunctions within the onboard gear. The company didn’t reply to a request for remark or publicly acknowledge the occasion on its social media channels.
NASA astronauts Butch Wilmore and Suni Williams boarded their Starliner spacecraft, the Boeing-built capsule that has been docked since June 6, on its first crewed take a look at mission on the station.
Three of the opposite American astronauts and a Russian cosmonaut boarded SpaceX’s Crew Dragon capsule that took them to the house station in March. The sixth American astronaut joined two different Russian cosmonauts within the Russian Soyuz capsule that carried them there final September.
Crash dangers
Area debris-generating occasions are uncommon however are a rising concern as house turns into more and more crowded with satellite tv for pc networks which might be very important to day by day life on Earth, from broadband web and communications to primary navigation companies.
In 2021, Russia hit one in all its defective satellites in orbit with a ground-based anti-satellite (ASAT) missile fired from its Plesetsk missile base. The explosion, which examined a weapons system forward of Russia’s 2022 invasion of Ukraine, created hundreds of items of house particles.
There was no speedy indication from airspace or maritime warnings that Russia had launched a missile to hit the RESURS-P1 satellite tv for pc, mentioned Jonathan McDowell, an area tracker and Harvard astronomer.
“I discover it arduous to imagine that they’d use such a big satellite tv for pc as an ASAT goal,” McDowell mentioned. He and different analysts speculated that the breakup was extra doubtless brought on by an issue with the satellite tv for pc, equivalent to leftover gas on board inflicting an explosion.
With roughly 25,000 items of particles bigger than 10 cm in house, specialists are involved in regards to the prospect of a Kessler impact – a phenomenon through which satellite tv for pc collisions with particles might create a cascade of extra harmful particles and exponentially enhance the prospect of a crash.
