“Surface changes on comet 67P/Churyumov-Gerasimenko suggest a more active past” by M. Ramy El-Maarry, O. Groussin, N. Thomas, M. Pajola, A.-T. Auger, B. Davidsson, X. Hu, S. F. Hviid, J. Knollenberg, C. Güttler, C. Tubiana, S. Fornasier, C. Feller, P. Hasselmann,...
"Comet 67P is coming alive," says Claudia Alexander, project scientist for the U.S. Rosetta Project at JPL. "And it is even more active than I expected." Launched in 2004, Rosetta has spent the past few years in hibernation as it chased the comet across the Solar System. In January ...

EUROPEAN spacecraft Rosetta released prober Philae to make the first-ever comet landing on Comet 67P/Churyumov-Gerasimenko on Wednesday morning, confirmed European Space Operations Centre in Darmstadt Germany.
Prospects in 2015: As of this writing,Comet 67P/C-Gis 1.9 AU from the Sun and closing. The ‘P’ in ‘67/P’ stands for ‘short term (less than 200 years) periodic,’ and the comet orbits the Sun once every 6.44 years. Perihelion for 67/P occurs on August 13th, 2015 when the...
Landslides have been invoked6 to explain some outbursts on comet 103P/Hartley 2, although the process required a pre-existing dust layer on the verge of failure. The Rosetta mission observed several outbursts from its target comet 67P/Churyumov–Gerasimenko, which were attributed to dust ...
The findings, published in The Astrophysical Journal, are based on data captured by the European Space Agency's (ESA) Rosetta mission during its two-year close flyby and observation of the comet 67P from 2014 to 2016. In 2015, ESA's Rosetta spacecraft detected the boulder shifting approximat...
Scientists uncovered new insights regarding the potential role of comets, particularly Comet 67P/Churyumov-Gerasimenko, in delivering water to early Earth. A new study led by Kathleen Mandt, a planetary scientist at NASA's Goddard Space Flight Center, has renewed focus on the role of Jupiter-fa...
Refractory and semi-volatile organics at the surface of comet 67P/Churyumov-Gerasimenko: Insights from the VIRTIS/Rosetta imaging spectrometer The VIRTIS (Visible, Infrared and Thermal Imaging Spectrometer) instrument aboard the Rosetta spacecraft has performed extensive spectral mapping of the su... ...
