The ESA will report the latest findings on the Rosetta Mission and Comet 67P over the next few days at the American Geophysical Union (AGU) meeting.
There should be some interesting results and below are a few of the many and varied Abstracts Submitted to this Session (Rosetta 2014), with many more to be found by following that link. Whatever subject floats your comet 67P boat should be covered.
Latest Rosetta Mission and comet 67P news
However 8P originates from the Oort cloud where the collisional activity is essentially non-existent. A contact-binary among the Jupiter family comets (JFC) such as 67P would have profound implications since it must be primordial and the comet must have survived a possible history of collisions in the Kuiper belt.
The Nucleus of Comet 67P/Churyumov-Gerasimenko : a New Case of Contact Binary?
Among the possible first signs of cometary activity that we shall discuss are distributions of pick-up ions possibly detectable by the Ion Composition Analyzer (RPC-ICA) and the Ion and Electron Sensor (RPC-IES), as well as ion cyclotron waves, generated by the pick-up process, which may be measured by the Fluxgate Magnetometer (RPC-MAG). Electron density and temperature measurements, and electric-field and waves measurements in the range from DC up to 3.5 MHz obtained by the Langmuir probes (RPC-LAP) and the Mutual Impedance Probe (RPC-MIP) will also be discussed.
First Results at 67P/Churyumov-Gerasimenko With the Rosetta Plasma Consortium
the Surface Electric Sounding and Acoustic Monitoring Experiment (SESAME) package was designed to measure the low frequency (Hz-kHz) electrical properties of the close subsurface of the nucleus.
At frequencies below 10 kHz, the electrical signature of the matter is especially sensitive to the presence of water ice and its temperature. PP-SESAME will thus allow to determine the water ice content in the near-surface and to monitor its diurnal and orbital variations thus providing essential insight on the activity and evolution of the cometary nucleus.
