Massive piece of space junk tossed from ISS sets new record

A pallet of batteries was released from the International Space Station, becoming the heaviest single piece of junk ever jettisoned from the station.

Mission controllers in Houston commanded the Canadarm2 robotic arm to release an external pallet loaded with the 2.9 tons of nickel-hydrogen batteries into Earth’s orbit Thursday morning.

“It is safely moving away from the station and will orbit Earth between two to four years before burning up harmlessly in the atmosphere,” NASA said in a statement.
