:Look, It’s a Sublimation Formation!
Instrument: Mercury Dual Imaging System – Narrow Angle Camera.
Located in the crater Eminescu, this high-resolution image shows part of the mountainous peak ring, as well as an example of the extensive formation of hollows located within the crater. Hollows maintain an air of mystery in the realm of planetary science. Though the exact formation mechanism is unknown, most scientists agree sublimation of volatiles holds the answer. This image highlights the prevalence of these hollows on and around the peak ring, as well as captures the beauty of such enigmatic formations.
This image was acquired as a high-resolution targeted observation. Targeted observations are images of a small area on Mercury’s surface at resolutions much higher than the 200-meter/pixel morphology base map. It is not possible to cover Mercury’s entire surface at this high resolution, but typically several areas of high scientific interest are imaged in this mode each week.
Welcome to the regional planetary image facility of Orsay
You have reached the portal to our public image database of solar system planets, developed in collaboration with NASA missions and ESA. In these pages we bring you news about the Photothèque website and a selection of space mission news highlights.
The planetary Photothèque is a facility proposed by the geomorphology and subsurface-atmosphere interaction team at the IDES Orsay lab.

The site’s features are reduced for a hardware failure forces us to renew the whole installation.
Everything will come back soon! Thank you for your patience!

The Photothèque Planétaire d’Orsay and the Centre de Vulgarisation de la Connaissance of Orsay Faculty of Sciences present an exhibition about Mars exploration history.IDES and IAS labs, currently involved in Mars space missions, provide their scientific oversight,
Visitors could admire ancient and new pictures of the Red Planet and its satellite Phobos, still mysterious, and they could play scientists in search of the best site for MSL rover landing.
The exhibition will begin Thursday, November 17, 2011 to the Bibliothèque Universitaire of the Faculty of Sciences. It will close on Thursday, December 15.
