European Space Probe Lands on a Comet

European Space Probe Lands on a Comet

7 hours after Europe’s Rosetta orbiter launched Philae, a washing-machine-sized robot probe, it landed on Comet 67P/Churyumov-Gerasimenko, a big ball of ice and rock 314 million miles away and traveling through space at 34,000 miles an hour. The ESA probe will remain there transmitting data until August 2015 as the comet slowly melts from the heat of the sun.

The international space mission has been a long time in the making. Comet-chasing Rosetta was launched ten years ago. The scientific importance of the Rosetta mission cannot be over-estimated. Comets are frozen repositories of early stages of the solar system.
