We're learning more about the comet that a European Space Agency paired up with its Rosetta probe last fall. For one thing, it has "goosebumps" on steep cliff faces. It's also highly porous.
The Beagle 2 Mars lander was lost in December 2003. Today, scientists confirmed their spacecraft was found partially deployed on the surface of the Red Planet.
An orbiting spacecraft caught the Philae lander bounding on the surface of Comet 67P/Churyumov–Gerasimenko. The lander sent home some scientific data before its batteries ran out.
As the Rosetta mission made history by putting a lander on a comet, one of its leading scientists drew wide criticism for wearing a shirt featuring lingerie-clad women.
Fearing that Philae's batteries won't last past Friday, engineers are looking at possible ways to help it get more power from its solar panels. One ray of hope: Its comet is heading toward the sun.
Before the Philae lander came to rest on the surface of a comet Wednesday, it bounced — twice. The lander weighs far less on the comet than it did on Earth.
A "mountain-sized" comet known as Siding Spring will pass very close to the red planet, where orbiters from the U.S., Europe and India, hope to get close — but not too close — to the action.
