Despite Concerns, Space Junk Continues to Clutter Earth Orbit

Posted on Categories Discover Magazine

Humans have a tendency to litter wherever we go. Whether it's the local park, a music festival, or Mt. Everest, we're just not good at cleaning up after ourselves. And space is no exception. Space is pretty big. Infinite, in fact. But the same can't be said of low-Earth orbit (LEO) and, in particular, the most popular orbital lanes used by Earth-sensing and communications satellites.
