The Planck consortium has published a statistical analysis of the dust polarization towards the regions of the sky best suited to measure Cosmic Microwave Background polarization. This work shows that dust polarization is significant over all of the sky, and that the signature of cosmic inflation will not be detected unless contamination associated with the dusty and magnetized interstellar medium in the Galaxy is removed with the required accuracy and confidence.
The target region of Rosetta’s lander Philae has been selected: the site offers a unique scientific potential with hints of activity nearby, minimum risks to the lander and good conditions to exploit energy resources. Landing is scheduled for November 11.
Two months prior to its separation, descent, and landing on the Churyumov-Gerasimenko nucleus, the Philae lander of the ESA Rosetta mission delivers its first images of the comet. The 7 micro-cameras of the CIVA instrument, designed and developed under IAS responsibility, will acquire the full 360° panorama of the landing site.
Jean-Loup Puget, Directeur de Recherche at CNRS, working at Institut d'Astrophysique Spatiale, has received the 2014 Space Science Award of COSPAR (Committee on Space Research). This Award honors a scientist who has made outstanding contributions to space science.
The COSIMA instrument on board the Rosetta spacecraft will provide the first high resolution mass spectra of grains collected close to a comet. The imaging system of COSIMA, COSISCOPE, built by Institut d’Astrophysique Spatiale, will locate and characterize the collected cometary grains.
