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.

After a ten-year-long interplanetary journey, Rosetta finally approaches its final destination, the nucleus of the comet Churyumov-Gerasimenko, on which the Philae module will land in November. The CIVA imaging system, designed to obtain a stereoscopic panoramic view of the surface of the comet after the landing of Philae, has just been turned on successfully, after years of hibernation, at a distance of more than 600 million km from the Sun.

The source region on Mars was probably impacted about 3 million years ago by a medium-size body, and the meteorites ended their space journey at the Earth’s surface a few thousand years ago.
