Episode 457 - Not so Empty Space near Earth

November 15, 2021

Space  is big and vast, but whilst not densely packed like in Sci Fi, there's still so much going on around Earth's orbit. Mapping out the local neighborhood around Earth's orbit is tricky but important work. We think we have an idea about most Near Earth Asteroids but occasionally they can sneak up on is. A chip off the old block of the Moon has become one of our newest near Earth Objects. How we clean up space junk without touching it or grabbing it with a rocket?
