In June 2008, a lander mission called Phoenix could deliver tools to search for habitable zones and the history of water on Mars. NASA today announced that the University of Arizona Lunar and Planetary Laboratory’s Phoenix mission has been selected as one of four candidates to fly NASA’s first Mars Scout Mission, cost-capped at $325 million, planned for launch in 2007. Peter H. Smith of the UA Lunar and Planetary Laboratory heads the Phoenix mission.
