Humans Just Got Our First Close-Up Look At A Comet And It's Mind-Blowing
Ten years ago the European Space Agency launched Rosetta, a first-of-its-kind spacecraft on a mission to meet a comet.
That comet? 67P/Churyumov-Gerasimenko.
It finally accomplished that goal earlier this month - getting into the comet's orbit. But she's not done yet.
This November Rosetta will deploy a small probe that, if successful, will land on the comet - the first time we've ever made contact with a space rock (intentionally).
Before Rosetta, we knew comet 67P/Churyumov-Gerasimenko as just a speck of light - as we do most comets. It's hard to really see what a comet is like because they're extremely small. Here's what the comet looks like from Earth:
The left half of the image is a profile of the comet's body and the right half is the back of the comet's head, near to where Rosetta's probe will land.
Another close up, taken Sept 14, was taken about 19 miles from comet 67P/Churyumov-Gerasimenko. Scientists were surprised they found no traces of water ice on the comet's black-as-coal surface. The comet only looks grey because of the intense blackness of space behind it. On Monday, ESA scientists announced where the Philae lander will attempt to touch down. The location, simply dubbed "Site J", is located on the head of the comet and was selected amongst five final candidate landing locations. The back-up site for Philae will be "Site C," located on the body of the comet. Site J, however, offers minimum risk to the lander compared to other candidate sites.
