Scientists from the ESA's Rosetta mission are honoring their deceased colleague, Claudia Alexander of NASA's Jet Propulsion Laboratory by naming a feature after her on the mission's target, comet 67P/Churyumov-Gerasimenko.
ESA's Rosetta spacecraft has provided evidence for a daily water-ice cycle on and near the surface of comets.
On Sept. 13, 2015, the Solar and Heliospheric Observatory -- a joint project of the European Space Agency and NASA -- discovered its 3,000th comet, cementing its standing as the greatest comet finder of all time.
On 30 July, the first papers covering the scientific results obtained by Philae on the surface of Comet 67P/Churyumov-Gerasimenko were published in Science magazine.
On 13 August, Comet 67P/Churyumov-Gerasimenko reaches its closest point to the Sun (perihelion) and the Rosetta orbiter will be there to see exactly what happens.
The Rosetta orbiter is continuing its science until the end of the extended Rosetta mission in September 2016. The lander's future is less certain. This film covers some of what we've learnt from Philae about comet 67P/Churyumov-Gerasimenko so far.

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.
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.
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.
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 has woken up after seven months in hibernation on the surface of Comet 67P/Churyumov-Gerasimenko.
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 image was captured on 19 October 2014 and looks across the neck from the comet's small lobe in the foreground to the large lobe in the background.
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.
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.
