NASA Selects First Mars Scout Concepts for Further Study

http://www.spaceref.com/news/viewpr.html?pid=5150

The ten most promising mission concepts of the 43 proposed to NASA for
possible launch to Mars in 2007 were selected today to receive funding for
six months of continued studies. Included in the ten concepts selected for
study are missions to return samples of martian atmospheric dust and gas,
networks of small landers, orbiting constellations of small craft, and a
rover that would attempt to establish absolute surface ages of rocks and
soils.

Defrosting Martian Sand Dunes in Late Southern Winter

http://www.spaceref.com/news/viewpr.html?pid=5142

As winter gives way to spring in the martian southern hemisphere, the
Mars Global Surveyor is observing the retreat of the south polar frost
cap as sunlight falls upon it for the first time in several months. One of
the most aesthetically-pleasing aspects of the spring defrosting process
is the pattern that is created on the martian sand dune fields.
