Yesterday, when the Rosetta spacecraft was a mere 234 kilometers (145 miles) from the comet 67P/Churyumov-Gerasimenko (or just ChuGer) it took this amazing image with its navigational camera...

Mind you, the main OSIRIS camera has more resolution than the NAVCAM, so we'll be getting better pictures soon. And of course, Rosetta is still on the approach!


UPDATE: A second close up photograph:

Presently, astronomers only have a short period of observations to forecast the comet's path through the inner solar system and they know the probability of Mars "taking one for the celestial team" on Oct. 19, 2014, is small — in all likelihood the comet will fly by, creating a wonderful astronomical event for Earth and Mars-based observers alike.

History was made Wednesday when the European Space Agency successfully landed a spacecraft on a comet for the first time ever.

"We are the first to do this - and that [achievement] will stay forever." said Jean Jacques Dordain, Director General of ESA.



The comet, 67P/Churyumov–Gerasimenko, orbits, the sun every 6.45 years. It is 2.1 miles wide by 2.4 miles long.

Rosetta first launched in 2004 to research the comet, and it didn't arrived at its destination until this past August. On Wednesday morning, Philae first separated from the probe to attempt a landing.

Researchers are hoping to learn more about the origins of the solar system and whether or not comets could have brought water and life to Earth. Watch an ESA animated explanation of Rosetta's journey to the comet and it's surface mission below.
