Abstract:
Abstract
ESA’s Rosetta mission arrived on August 6, 2014, at target comet 67P/Churyumov-Gerasimenko after 10 years of cruise. OSIRIS (Optical, Spectroscopic, and Infrared Remote Imaging System) is the scientific imaging system onboard Rosetta. It comprises a Narrow Angle Camera (NAC) for nucleus surface and dust studies and a Wide Angle Camera (WAC) for the wide field coma investigations.
We present the first science results achieved by OSIRIS from the arrival at the comet throughout the mapping phase. The overview will cover surface morphology and activity of the nucleus as seen in gas, dust, and local jets.
