Tethered space net (TSN)
Figure 3.
Tether space system step-by-step operation. Start: stowed structure on the satellite; first step: deployment of the stiffer boom; second step: deployment of the tubular booms and opening of the net, checking the opening area; third step: contact of the net with the debris; fourth step: retracting the tubular boom, checking the closing time.
