A camera closes in on a detailed model satellite, to simulate the extreme 'guidance navigation and control' (GNC) challenge of rendezvousing with an uncooperative target, such as a derelict satellite or distant asteroid.
This scene takes place in ESA's GNC Rendezvous, Approach and Landing Simulator, or GRALS, based at the ESTEC technical centre in the Netherlands, which is used to test vision-based navigation algorithms as well as cameras in development for future space debris removal, as well as the Hera asteroid mission for planetary defence.
GRALS is the Agency's single longest lab, incorporating a 33-m long railing. Camera-carrying robotic arms can be mounted onto this railing to mimic the entire cycle of closing in upon a rendezvous target.

In the not-too-distant future an international regulatory and enforcement agency may be looking for Space Traffic Controllers to fill hundreds of positions for well-trained professionals.
It is likely that these positions will be located in an international metropolis such as Washington, Paris, London, Hong Kong, Rome or Moscow. Applicants must pass a rigorous training program including many hours in class and in simulators. They will probably be required to have prior training in spacecraft dynam ... read more
