  • Goal 1 -- Life: Determine if life ever arose on Mars Determine if life exists today Determine if life existed on Mars in the past Assess the extent of prebiotic organic chemical evolution on Mars Goal 2 -- Climate Characterize Mars’ present climate and climate processes Characterize Mars’ ancient climate and climate processes Goal 3 -- Geology Determine the geological processes that have resulted in formation of the Martian crust and surface Characterize the structure, dynamics, and history of Mars interior Goal 4 -- Prepare for human exploration Acquire Martian environmental data set (such as radiation) Conduct in-situ engineering/science demonstration Establish infrastructure for future missions
  • With goals to detect health hazards for future human space explorers, to discover what our neighboring planet is made of, and to find buried water ice in the shallow subsurface of Mars, the 2001 Mars Odyssey orbiter has achieved mission success. &amp;quot;As of August 24, 2004, the end date for its primary mission, Odyssey has officially fulfilled its science goals, and we look forward to refining our understanding of the red planet throughout an extended mission,&amp;quot; said Dr. Jeff Plaut, Odyssey project scientist.

  • Magellan was ripped apart in the Philippines. 260 sailors, 5 ships, 3 years later 1 ship returned with 16 men Magellan crews dying daily, and the living surviving by eating rats and boiled leather. Columbus: #1--3 ships, 104 men. Lost 2 ships and most of the men (40 killed in the new world) #2--With 17 ships, 1,200 men and boys #3The monarchs financed yet another voyage for Columbus. On May 30, 1498, Columbus set sail with six ships.= Columbus was arrested and sent back to Spain in chains. #4—10 years later with four ships and 150 crewmen, one being his 13-year-old son, Diego.

    4. 4. Exploring Mars: Following the Water Why Mars? It is the most Earth-like of the planets The most likely to have past or present life Reachable every 26 months Why Water? Liquid water is required for life as we know it. Climate Life Common Thread Human Exploration Geology W A T E R When Where Form Amount
    5. 5. Today’s Robotic Mars Exploration Program Redefined in October 2000 after twin failures in 1999 A science-driven effort to characterize and understand Mars as a dynamic system, including its present and past environment, climate cycles, geology, and biological potential. Central among the questions to be asked is… “ Did life ever arise on Mars?” The science strategy is known as “Follow the Water.” Mars Global Surveyor Mars Exploration Rovers Mars Odyssey Phoenix Scout Mars Reconnaissance Orbiter Mars Science Laboratory
