Video: Mission control celebrates separation but anxiety builds over landing

Emboldened by renewed contact with Europe’s comet lander, engineers are repositioning the mission’s Rosetta mothership this week to establish a reliable a communications link with the dishwasher-sized Philae landing craft, a prerequisite for resuming a science campaign abbreviated by a power shortfall last year.

We speak with Matt Taylor, Rosetta Project Scientist, at the European Space Agency’s mission control in Darmstadt, Germany, about the plan to crash land the spacecraft on Comet 67P/Churyumov–Gerasimenko.

For some comets, breaking up is not that hard to do. A new study indicates that the bodies of some periodic comets — objects that orbit the Sun in less than 200 years — may regularly split in two, then reunite down the road. This may be a repeating process fundamental to comet evolution.
