Rosetta's Path

Rosetta's investigations of its comet are continuing as the mission teams count down the last month to perihelion the closest point to the Sun along the comet's orbit when the comet's activity is expected to be at its highest.

Philae Contacted and Successfully Executes Commands

Philae Contacted and Successfully Executes Commands

The Philae lander communicated with the Rosetta orbiter again between 19:45 and 20:07 CEST on 9 July 2015 and transmitted measurement data from the COmet Nucleus Sounding Experiment by Radiowave Transmission (CONSERT) instrument.


Active Pits Found on Rosetta's Comet

Active Pits Found on Rosetta's Comet

Some of the dust jets emitted from Rosetta's comet can be traced back to active pits on its surface. They could be the remnants of collapsed cavities.


Exposed Water Ice Detected on Surface of Comet 67P

Using the high-resolution science camera on board ESA's Rosetta spacecraft, scientists have identified more than a hundred patches of water ice a few metres in size on the surface of Comet 67P/Churyumov-Gerasimenko.


Rosetta's Lander Philae Wakes Up from Hibernation

Rosetta's Lander Philae Wakes Up from Hibernation

Rosetta's lander Philae has woken up after seven months in hibernation on the surface of Comet 67P/Churyumov-Gerasimenko.


Rosetta Reveals Surprises in Comet 67P's Coma

Rosetta Reveals Surprises in Comet 67P's Coma Video in Story

Rosetta's continued close study of Comet 67P/ChuryumovGerasimenko has revealed an unexpected process at work, causing the rapid breakup of water and carbon dioxide molecules spewing from the comet's surface.

This single frame Rosetta navigation camera image of Comet 67P/Churyumov-Gerasimenko was taken on 15 April 2015 from a distance of 170 km from the comet center.


Rosetta and Philae Find Comet 67P Is Not Magnetized

Rosetta and Philae Find Comet 67P Is Not Magnetized

Studying the properties of a comet can provide clues to the role that magnetic fields played in the formation of solar system bodies almost 4.6 billion years ago.

Rosetta's OSIRIS Detects Hints of Ice in Comet 67P's Neck

The Hapi region on the neck of Rosetta's comet 67P/Churyumov-Gerasimenko reflects red light less effectively than most other regions on the comet. It thus appears slightly bluish.


OSIRIS Catches Glimpse of Rosetta's Shadow

OSIRIS Catches Glimpse of Rosetta's Shadow

OSIRIS images taken during Rosetta's close flyby on 14 February show 67P's surface in remarkable detail and the shadow of the spacecraft encircled in a wreath of light.
