Astroscale said its Japan unit would sign the five-year contract with the Japan Aerospace Exploration Agency (JAXA) on Tuesday.
The agreement will see the startup remove the upper stage of JAXA’s H-IIA rocket, which was launched in 2009 and has been in orbit about 600 km (373 miles) above the earth’s surface.
Astroscale will develop a new spacecraft named ADRAS-J2 that will equip robotic arm technologies to capture the target debris by March 2029, the company said in a statement.
Debris is increasingly becoming a risk for space missions, as the number of satellites in orbit has risen sharply.
A Chinese rocket stage that broke apart in space earlier this month created more than 700 pieces of debris in the latest addition to the hazardous collision risks. ($1 = 147.9200 yen)
