Committee releases shortlist of Mars landing sites

Experts worry practicality may win over science in final selection.

Six potential landing sites have been chosen for NASA's Mars Science Laboratory, a large rover set to assess the past habitability of sites on the planet's surface, when it lands in October 2010 (See image). The shortlist, chosen from dozens of possibilities, includes craters partly filled with sediment, an ancient flood channel and regions rich in clay minerals thought to date from an era when the martian surface was wetter than it is today.
