The Sky at Night (1957) : 2014x7

The team goes behind the scenes at mission control for the critical point of the most ambitious space project of the decade. The European Space Agency's Rosetta probe finally catches up with the comet it has been chasing across the solar system for ten years and prepares to send out a lander armed with drills and harpoons for a daredevil attempt to hitch a ride. With the latest images revealing that it may even be two comets stuck together, Dr Chris Lintott is on hand in Germany with updates from the mission team on this unparalleled challenge, whilst Dr Maggie Aderin- Pocock reveals the instruments that the lander is carrying.
