  2. SpaceBlower: a rocket to combat space debris

    Date de publication:

    8 Octobre 2020

    SpaceBlower is a light suborbital rocket designed to eject a cloud of particles into the path of large non-manoeuvrable space debris. Its goal is to avoid collisions likely to generate thousands more debris fragments and thus to keep satellites and their orbits safe. Space Blower is a preliminary project initiated and funded by CNES and its partner Bertin Technologies (now CT France). Christophe Bonnal, senior expert at CNES’s Launch Vehicles Directorate, outlines what this project is aiming to accomplish.
