Rosetta, Europe's Comet-Chasing Spacecraft: Latest News, Images and Video

Gravity measurements taken by the orbiting Rosetta spacecraft show the body of comet 67 P/Churyumov-Gerasimenko is about 75 percent dust and 25 percent ice all the way through.

The odds aren’t great. Engineers don’t even know if Philae still has a working receiver and the probe could be covered in dust.

In a surprise finding for scientists, the Rosetta spacecraft detected molecular oxygen in the gas streaming off comet 67P/Churyumov-Gerasimenko.

Scientists with ESA's Rosetta mission named two surface features on comet 67P/C-G for scientists from the mission team who recently passed away.
