The science geek on your shopping list is gonna love this: The UA's Lunar and Planetary Lab has assembled a dazzling 2011 calendar with luscious shots of Mars taken by the HiRISE camera aboard the Mars Reconnaissance Orbiter. A mere $15—and you're supporting the space program! Details on ordering here.

The HiRISE team has recently uploaded another big batch of Martian surface photos you can browse here.

HiRISE team member Laszlo Kestay tells us about the aureole of Olympus Mons in the photo above:

The aureole that surrounds the Western and Northern sectors of Olympus Mons has puzzled Mars geologists. The most common idea is that these deposits formed as giant land slides as the volcano partially collapsed under its own weight.

This HiRISE image is centered on a dark and relatively dust-free part of the aureole. Where the dust

has been stripped off, swirling bands of darker and lighter rocks are visible. These suggest gently warped layers that have been exposed by erosion. In fact, many of the small pinnacles and mesas in this area are being eroded by the wind in the same way as layered deposits in other parts of Mars.

However, there are also blocks that shed dark material, that could be broken up lava rock. The many dunes in the area suggest that much of the debris is sand sized.
