After a 10-year journey aboard the spacecraft Rosetta, the lander Philae touched down on the nucleus of comet 67P/Churyumov-Gerasimenko and took a picture of its surface. Although harpoons intended to anchor Philae to the comet did not deploy, it appears to be in a stable position. The lander has to deal with a problem not experienced with spacecraft sent to larger celestial objects.
Gravity on the comet is 1/100,000th that of Earth, meaning the lander weighs only 0.04 ounces there.Read the full story, and of course, look at the picture.
UPDATE: The Guardian has more.
