"Early this morning US Eastern Time, the MarsScience Laboratory (aka Curiosity rover) successfully landed on Mars. "Curiosity's main assignment," according to NASA, "is to investigate whether its study area ever has offered environmental conditions favorable for microbial life." To achieve its two year exploratory mission, the nuclear powered Curiosity carries 15 times as much scientific equipment as on previous Mars rovers. Curiosity will analyze samples of soil, rocks and atmosphere on the spot and transmit results back to NASA scientists. NASA claims that "Curiosity is a bold step forward in learning about our neighboring planet." Importantly, according to Doug McCuistion, director of the Mars Exploration Program at NASA Headquarters in Washington, D.C., "This mission transitions the program's science emphasis from the planet's water history to its potential for past or present life."
If you are interested in learning about the possibility of current life on Mars, Curiosity is not designed to answer that. "
