Phoenix
Launched in August 2007 and will arrive at Mars on 25 May, landing at the southern edge of the planet's ice-rich northern polar cap. It will dig up samples of the ice and soil there, looking for complex organic molecules and investigating whether conditions there might once have been favorable to life.
