Comet Scientists Honor Colleagues
Scientists from the European Space Agency Rosetta team have honored two late team members by naming comet features after them. The comet is 67P/Churyumov-Gerasimenko, where the mission successfully landed a probe. One of the features is shown here in these Rosetta images, with...

First Panoramic View from Comet Lander
The Philae lander of Europe Rosetta mission has returned the first panoramic image from the surface of a comet. The unprocessed panorama from the lander CIVA-P camera shows a 360-degree view around the point of final touchdown.

Welcome to a Comet, from Lander on Surface
The Philae lander of the European Space Agency Rosetta mission is safely on the surface of Comet 67P/Churyumov-Gerasimenko, as these first two images from the lander CIVA camera confirm. One of the lander three feet can be seen in the foreground.
