The International Space Station fired its thrusters to maneuver retired of the mode of a portion of oncoming Russian abstraction junk, NASA said precocious Monday.

The abstraction bureau said successful a quality merchandise that the ISS conducted a 5 minute, 5 2nd pain to debar a fragment of Russia’s Cosmos 1408 satellite, which the state destroyed successful a weapons trial successful November past year.

Officials astatine NASA person antecedently warned astir the risks of the proliferation of debris successful space, caused by a melodramatic summation successful the fig of satellites successful orbit and respective instances of governments intentionally destroying satellites and creating caller plumes of junk.

The abstraction presumption conducted a “Pre-Determined Debris Avoidance Maneuver,” oregon PDAM, to springiness the ISS “an other measurement of region distant from the predicted way of a fragment of Russian Cosmos 1408 debris,” the abstraction bureau said.

“The thruster firing occurred astatine 8:25 p.m. EDT and the maneuver had nary interaction connected presumption operations. Without the maneuver, it was predicted that the fragment could person passed wrong astir 3 miles from the station.”

The pain raised the abstraction station’s altitude by 2/10 of a mile, according to the abstraction agency.

On November 15, 2021, Cosmos 1408, a nary longer operational satellite, was destroyed, generating a unreality of debris including immoderate 1,500 pieces of trackable abstraction debris.

US Space Command said Russia tested a direct-ascent anti-satellite, oregon DA-ASAT rocket and powerfully condemned the anti-satellite test, calling it “a reckless and unsafe act” and saying that it “won’t tolerate” behaviour that puts planetary interests astatine risk.

The ISS was forced to marque a akin maneuver successful June to debar debris created by the anti-satellite test. In January, a portion of debris created by that trial came wrong striking region of a Chinese satellite, successful an brushwood the Chinese authorities called “extremely dangerous.”

The ISS typically has to displacement its orbit to debar abstraction junk astir erstwhile a year, maneuvering distant from the entity if the accidental of a collision exceeds 1 successful 10,000, according to NASA.

Invisible successful the nighttime sky, determination are hundreds of millions of debris objects orbiting our planet. This debris is composed of parts of aged satellites arsenic good arsenic full defunct satellites and rocket bodies.

According to a 2021 study by NASA, astatine slightest 26,000 of the pieces of abstraction junk orbiting the Earth are the size of a softball oregon larger – large capable to wreck a satellite; much than 500,000 pieces of debris are marble-sized – susceptible of damaging spacecraft; portion “over 100 cardinal pieces are the size of a atom of brackish that could puncture a spacesuit.”

As these fragments sound into each other, they tin make yet much pieces of smaller orbital debris.

Russia said earlier this twelvemonth it is readying to propulsion retired of the International Space Station and extremity its decades-long concern with NASA astatine the orbiting outpost, which is owed to beryllium retired by 2031.
