Astroscale is a company that was created to find solutions for orbital debris

Astroscale is a company that is interested in removing orbital debris through EOL and ADR services. The company was founded by Mitsunobu Okada and Nobu Okada in 2013, in Sumida, Tokyo, Japan.

The company recognizes the amount of debris that occupies orbital space consists of millions of pieces of trash that can measure up to 10cm in diameter. Since they expect to see thousands of satellites launch within the next decade, they look to develop sustainable technologies to help remove and secure debris.
