possible mission to Mars in 2007 would scrutinize the martian atmosphere for any chemical traces of life, or even environments supportive of life, anywhere on the planet. An international team led by Dr. Mark Allen, an atmospheric chemist at NASA’s Jet Propulsion Laboratory, Pasadena, Calif., developed the mission proposal named Mars Volcanic Emission and Life Scout, or Marvel. Today, NASA announced that Marvel is one of four finalists in competition for the first Mars Scout Mission for the 2007 launch opportunity. Final selection by the NASA associate administrator for space science, Dr. Edward Weiler, will be made by late next summer.
