How Space Agencies Safely Decommission Satellites And Retired Spacecraft

4 days ago | rfglobalnet.com | John Oncea

By John Oncea, Editor Earth has a growing space junk problem, with three sizable pieces of debris crashing onto our planet every day. To combat that, space agencies are using targeted reentry, graveyard orbits, and RF tracking to safely dispose of retired spacecraft. Did you hear about the 53-year-old Soviet Venus lander that fell from the sky? According to Space, “The Kosmos 482 probe crashed to Earth (on May 10) after circling our planet for more than five decades.
