e.Deorbit is a planned European Space Agency active space debris removal mission developed as a part of their Clean Space initiative. The launch is planned for 2023 on board a Vega launch vehicle.
A 1,600-kilogram (3,500 lb) spacecraft will be launched on board a Vega rocket into a polar orbit at an altitude of 800–1,000 kilometres (500–620 mi). Once on orbit, the spacecraft will rendezvous with a derelict satellite in an unknown condition, inoperative, and probably tumbling.
Capture will be conducted in one of two ways: either by using mechanical tentacles or nets. The tentacles option includes equipping the spacecraft with robotic arms, one of which will first capture a holding point, before the remaining arms embrace the derelict and secure it with a clamping mechanism. The net option includes equipping the spacecraft with a deployable net on a tether, that will envelope the target derelict before the spacecraft will begin changing orbit.:13,24,25 The net option has the advantage of being able to capture objects with a wide range of sizes and spins.
The mission was developed at ESA's Concurrent Design Facility, with studies for the Clean Space programme on de-orbiting techniques being carried out in 2009. The first symposium about the mission took place in May 2014. Early testing included successful attempts at capturing scale model satellites by shooting nets from compressed air ejectors. The first design stage was completed in June 2015, with a systems requirements review being conducted in May–June 2016 and a final mission approval taking place in December 2016.
