After a ten year journey, NASA’s New Horizons mission is still 420 million kilometers from the Pluto system – but that’s close enough to begin to see the orbital dance of an icy world and its major moon. This far out from the Sun it’s easier for planetary objects to hold onto satellites, so even [...]

(ESA)

Over the coming month the European Space Agency’s (ESA) Rosetta mission will fire its main engines no less than eight times to tweak its interplanetary intercept course with Comet Churyumov–Gerasimenko; eventually sidling up to the 4 kilometer wide cometary nucleus at about 7.9 meters per second in early August.
