Shortly before Philae’s touchdown on Comet 67P/C-G, the lander’s down-looking descent camera, ROLIS, imaged the surface of the comet:
The image shows was acquired during descent on 12 November 2014 at 14:38:41 UT, from a distance of approximately 3 km from the surface. The landing site is imaged with a resolution of about 3m per pixel.
The ROLIS instrument is a down-looking imager that acquires images during the descent and doubles as a multispectral close-up camera after the landing. The aim of the ROLIS experiment is to study the texture and microstructure of the comet’s surface.
In the upper right corner a segment of the Philae landing gear is visible.
ROLIS (ROsetta Lander Imaging System) is a descent and close-up camera on the Philae Lander. It has been developed by the DLR Institute of Planetary Research, Berlin.
