All year we are following ESA’s Rosetta mission as the team hunts down a comet and then puts a lander on its surface. How are they progressing?
Jake and Armelle are in the clean room at ESA’s operations centre in Germany, testing commands on an exact copy of the spacecraft:
Jakub Urbanek, Rosetta Operations Engineer explains the role of the replica: “While Rosetta is flying far away we have a fully functional model here at ESOC that we can use to test out various things that we want to do.”
Armelle Hubault another engineer on the Rosetta project gives an insight into high-tech comet hunting: “We have a complete set of instruments on board Rosetta, which allow us to observe the comet from afar. We can monitor ultraviolet rays and infrared, etc.”
