The HiRISE camera on NASA's Mars Reconnaissance Orbiter took a huge, detailed image of Mars' Mojave crater on Jan. 7, 2007. Part of that photograph shows the central uplift structure in the crater. Rocks that form this peak were several kilometers beneath the surface until an impact formed the 37 mile-diameter (60 kilometer) crater just north of Mars' equator. The HiRISE image shows that boulders as large as 50 feet across (15 meters) have eroded from the massive uplifted rock and rolled downslope.

The HiRISE image also confirms earlier evidence that this part of Mojave crater appears untouched by liquid water.

Previous photographs taken by the HiRISE camera, and even earlier by the Mars Orbital Camera that flew on NASA'S Mars Global Surveyor, show that Mojave crater rim walls feature striking drainage channels and alluvial fans that likely were formed by surface water runoff.

How runoff formed these channels and alluvial fans is one of the questions that HiRISE team members and their collaborators are looking into.

MRO Conducts Details Survery Of Mars Pathfinder Landing Site And Surroundings

Pasadena CA (JPL) Jan 11, 2007
The high-resolution camera on NASA's Mars Reconnaissance Orbiter has imaged the 1997 landing site of NASA's Mars Pathfinder, revealing new details of hardware on the surface and the geology of the region. Pathfinder landed on July 4, 1997, and transmitted data for 12 weeks. Unlike the two larger rovers, Spirit and Opportunity, currently active on Mars, Sojourner could communicate only with the lander, not directly with Earth.
