... near-Earth asteroids), planetary defence efforts have not risen to the level, or the budgets, of having dedicated spacecraft missions. The most immediately relevant objects for planetary defence are asteroids of an intermediate scale, ones on the...
... missions to perform deorbiting manoeuvres, and hence self-deorbiting is often not possible. As such, ADR by means of remover spacecraft seems to be inevitable. In the net removal method a net is deployed towards the target which is captured and then...
... mass of 800kg – less than a third of Rosetta’s launch mass. Measuring 1.8 x 2.0 x 2.1m across with solar arrays stowed, the spacecraft design is a simple one with fixed solar arrays, a fixed high-gain antenna and a bipropellant propulsion system...
... as a failure by the fault detection and recovery logic. Also the whole swing-by scenario had to be re-designed to establish a spacecraft configuration that would minimise power consumption whilst in the shadow. It was not an easy task but we had...
