Here's a look at the final cut:
_ Gale crater located near the Martian equator possesses a 3-mile-high mound of layered mineral deposits.
_ Mawrth Vallis is an ancient flood channel in the Martian northern highlands that is rich in clay minerals.
_ Eberswalde crater in the southern hemisphere contains remnant of a river delta.
_ Holden crater, close to Eberswalde, is the site of water-carved gullies and sediment deposits.
The shortlist was culled from nearly 60 hopefuls in a selection process that began in 2006.
