Rosetta Update: Philae Landed in a Hole

The exact location of Philae’s landing site remains unknown, though the site’s topography might allow the lander to operate longer than planned. Meanwhile, Rosetta is detecting organics and heavy elements even when Comet Churyumov-Gerasimenko is far from the Sun.

Rosetta Catches Its Comet

On August 6th, the ESA's Rosetta spacecraft finally completed its decade-long voyage to Comet 67P/Churyumov-Gerasimenko.

Rosetta's Comet has a Split Personality

The Rosetta spacecraft is closing in on Comet 67P/C-G, providing astronomers with an ever more detailed view of its structure. Judging by the latest photos, it actually has two components and is shaped like… a rubber ducky?

Rosetta's Comet Sleeps Again

Comet 67P/Churyumov-Gerasimenko only woke briefly before starting another nap, expected on-again-off-again behavior that bodes well for the comet-chasing spacecraft's arrival in August 2014.

Rosetta's Comet Awakens

The Rosetta spacecraft took these images of Comet Churyumov–Gerasimenko as it approaches the nucleus. It'll launch its lander, Philae, in November onto the nucleus's surface.

The End of Rosetta's Big Sleep

Europe's comet-chasing spacecraft woke up after a 957-day-long hibernation to begin the most comprehensive comet study to date. Part of its mission: attempt to place an instrumented lander on a comet’s nucleus for the first time.
