New Mexico gadget hints at water on Red Planet The Albuquerque Tribune

When the Mars Observer spacecraft disappeared into the cold void of space nine years ago, it broke Bill Feldman’s heart. Feldman, 62, a Los Alamos National Laboratory scientist, had worked since 1984 to develop an instrument for the spacecraft called a neutron spectrometer. There was no room to fit the instrument, which is smaller than a shoe box and weighs about 8 pounds, on subsequent missions to the planet until the Mars Odyssey spacecraft. It took nearly a decade, but Feldman finally got a second chance with Odyssey, which was launched in early 2001 and successfully reached orbit in October. A few months ago, the instrument returned some surprising results – including showing that hydrogen, which many think indicates water, is more abundant on Mars than previously believed.
