A Retired Weather Satellite's Surprising End

A weather satellite that's been retired for a while, just floating in space. Well, an old one from a military program called DMSP-5D2 F14 has broken up into over 50 pieces. Why's this a big deal? This satellite was launched in 1997 and has been orbiting ever since its retirement in 2020. Now, it's adding to the growing problem of space junk. This isn't the first satellite from this program to break up. In 2016, F12 met a similar fate, and even further back in 2015, F13 did too. The reason? A design flaw in the batteries that makes these satellites vulnerable to exploding. You might be thinking, "Couldn't they stop this from happening? " They tried. Passivation is a process where they drain the batteries and vent fuel tanks to prevent explosions. But sometimes, older satellites just don't respond well to this. They weren't designed with the same rules we have today to prevent space junk. "But why should we care about this? " you ask. Space junk is dangerous. It can collide with other satellites or even spacecraft, causing big problems. So, keeping track of all this is important. Two companies, LeoLabs and Slingshot Aerospace, were watching this breakup. Interestingly, they had slightly different times for when it happened. LeoLabs reported tracking over 50 pieces. It's like a big space puzzle, trying to keep track of all these pieces.
