Two NASA astronauts did some home maintenance Friday on the orbiting laboratory 200 miles above Earth during a seven-hour spacewalk. Astronauts Bob Behnken and Chris Cassidy ventured out of the International Space Station Friday morning to install batteries outside the station. Once outside, the astronauts began work on one of two power channels on the far starboard truss of the station. https://t.co/SN3Y9zOMwr — NASA (@NASA) June 26, 2020As he stepped out of the ISS, Cassidy lost a small mirror on his spacesuit adding to the millions of pieces of junk orbiting the Earth. While millions of pieces of space debris orbit Earth, more than 20,000 items including old rocket parts and busted satellites are big enough to be tracked in order to safeguard the space station and functional satellites.
