1
ClearSpace
Country: Switzerland | Funding: $37M
ClearSpace provides services for maintenance and removal of malfunctioning satellites and other space debris from the Earth orbit. The company (in partnership with the European Space Agency) is preparing the ClearSpace-1 mission to demonstrate the ability to remove the inoperative PROBA-1 satellite from low-Earth orbit. For this it's developing the "Claw" grappling system, which includes a robotic arm for the dexterous manipulation and capture of fragile space objects and control algorithms that enable fully autonomous grappling sequences. Another mission, CLEAR (Clearing the LEO Environment with Active Removal), in partnership with the UK Space Agency, aims to remove two UK-registered defunct satellites from low-Earth orbit. The company is also developing its own space service, Geo Life Extension, to extend the life of satellites by restoring their functionality using semi-autonomous spacecraft.
