Phoenix Launch; Mission to the Martian Polar North

200786128Washington DC: National Aeronautics and Space Administration 2007. Presumed First Edition First printing. Comb binding. Very good. 50 pages including covers. Decorative front cover. Phoenix was an uncrewed space probe that landed on the surface of Mars on May 25 2008 and operated until November 2 2008. Phoenix was operational on Mars for 157 sols 161 days. Its instruments were used to assess the local habitability and to research the history of water on Mars. The mission was part of the Mars Scout Program; its total cost was $420 million including the cost of launch. The multi-agency program was led by the Lunar and Planetary Laboratory at the University of Arizona with project management by NASA's Jet Propulsion Laboratory. Academic and industrial partners included universities in the United States Canada Switzerland Denmark Germany the United Kingdom NASA the Canadian Space Agency the Finnish Meteorological Institute Lockheed Martin Space Systems MacDonald Dettwiler & Associates MDA in partnership with Optech Incorporated Optech and other aerospace companies. It was the first NASA mission to Mars led by a public university. Phoenix was NASA's sixth successful landing on Mars from seven attempts and the first in Mars' polar region. The lander completed its mission in August 2008 and made a last brief communication with Earth on November 2 as available solar power dropped with the Martian winter. The mission was declared concluded on November 10 2008 after engineers were unable to re-contact the craft. JPL declared the lander to be dead. The program was considered a success because it completed all planned science experiments and observations. The mission had two goals. One was to study the geological history of water the key to unlocking the story of past climate change. The second was to evaluate past or potential planetary habitability in the ice-soil boundary. Phoenix's instruments were suitable for uncovering information on the geological and possibly biological history of the Martian Arctic. Phoenix was the first mission to return data from either of the poles and contributed to NASA's main strategy for Mars exploration "Follow the water."
