Comet landing is a “go” despite thruster problem

November 12, 2014 Stephen Clark

A potential problem with a rocket thruster designed to keep the Philae lander from bouncing off comet 67P/Churyumov-Gerasimenko after touchdown Wednesday will make the probe’s daring descent even more challenging, officials said.
