Video: Flight director updates status of comet lander

Entering the final months of a 12-year mission, Europe’s Rosetta spacecraft is again moving closer to the oddball comet that has engaged scientists since it arrived in 2014, heading for a controlled “smash” landing on the comet’s rugged charcoal-colored surface at the end of September.

Research teams across Europe spent the last half-year meticulously going through a wish list of experiments for the Philae comet lander without knowing whether they would ever get a chance to execute the tasks.

The European Space Agency’s Rosetta mission will end Sept. 30 with a dicey descent to the core of comet 67P/Churyumov-Gerasimenko, a risky, but potentially rewarding finale punctuated by commands to automatically safe the probe’s rocket thrusters and turn off its radio transmitter.
