Hollows on Mercury: NASA's MESSENGER spacecraft discovered strange hollows on the surface of Mercury. Images taken from orbit reveal thousands of peculiar depressions at a variety of longitudes and latitudes, ranging in size from 60 feet to over a mile across and 60 to 120 feet deep.

Mariner 10's Mercury: Date: 29 Mar 1974 - A photomosaic of images collected by Mariner 10 as it flew past Mercury. It shows the southern hemisphere of the innermost planet. The spacecraft took more than 7,000 images of Mercury, Venus, the Earth and its Moon during its mission. Credit: NASA
Computer Simulated Global View of Venus Date: 29 Oct 1991 This global view of the surface of Venus is centered at 180 degrees east longitude. Magellan synthetic aperture radar mosaics from the first cycle of Magellan mapping are mapped onto a computer-simulated globe to create this image. Last Update: 11 Jul 2011 (AMB) Credit: NASA/JPL
Double Ring Crater - Date: 14 Jan 2008 MESSENGER's Narrow Angle Camera (NAC) on the Mercury Dual Imaging System (MDIS) during the spacecraft's flyby of Mercury on 14 January 2008. The scene is part of a mosaic that covers a portion of the hemisphere not viewed by Mariner 10 during any of its three flybys (1974-1975). The surface of Mercury is revealed at a resolution of about 250 m/pixel (about 820 feet/pixel).
Anyone Else Think This Looks Like the Cookie Monster? The MESSENGER spacecraft is the first ever to orbit the planet Mercury, and the spacecraft's seven scientific instruments and radio science investigation are unraveling the history and evolution of the Solar System's innermost planet, Mercury.
