Space Debris

Astroscale hit a major milestone Wednesday, when its space junk removal demo satellite that’s currently in orbit successfully captured and released a client spacecraft using a magnetic system. The End-of-Life Services by Astroscale-demonstration (ELSA-d) mission was launched in March, with the goal of validating the company’s orbital debris removal tech.…

The Oort cloud represents the very edges of our solar system. The thinly dispersed collection of icy material starts roughly 200 times farther away from the sun than Pluto and stretches halfway to our sun’s nearest starry neighbor, Alpha Centauri. We know so little about it that its very existence…
