Шаблон:Short description Шаблон:Lowercase title Шаблон:Outdated as of Шаблон:Use dmy dates Шаблон:Infobox spaceflight e.Deorbit was a planned European Space Agency active space debris removal mission developed as a part of their Clean Space initiative.[1][2] The launch was planned for 2025 on board a Vega launch vehicle.[3][4][5] Funding of the mission was stopped in 2018[6] in favor of the ClearSpace-1 mission, which is now under development.[7]
Overview
A Шаблон:Convert spacecraft was to be launched on board a Vega rocket into a polar orbit at an altitude of Шаблон:Convert. Once on orbit, the spacecraft would rendezvous with the derelict satellite Envisat which is in an unknown condition, inoperative, and probably tumbling.[2]
Capture would be conducted in one of two ways: either by using mechanical tentacles or nets. The tentacles option included 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 included equipping the spacecraft with a deployable net on a tether, that will envelop the target derelict before the spacecraft will begin changing orbit.[8]Шаблон:Rp The net option has the advantage of being able to capture objects with a wide range of sizes and spins.[9]
After successfully capturing the targeted derelict, the spacecraft would deorbit itself, performing a controlled atmospheric reentry.[5]
History
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.[5][10] The first symposium about the mission took place in May 2014.[1] Early testing included successful attempts at capturing scale model satellites by shooting nets from compressed air ejectors.[9] 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.[5]
