Mission to Harpoon Comet is Back on Track

Posted by michael on from the go-go-go dept.

An anonymous reader writes "The Rosetta mission planners have announced today that after an indefinite launch delay earlier this year, their goal of landing on a comet is back on track. Their new baseline target is a rendezvous with the comet, Churyumov-Gerasimenko, in November 2014. En route to the comet, Rosetta will inspect two asteroids (Otawara and Siwa) at close quarters."

    Yes. Centripetal force. The Earth is constantly changing direction (as it orbits), which means its velocity (speed with direction) is constantly changing. Change in velocity / time = acceleration. The direction of acceleraton is towards the sun.
