Spaceward Bound event in the Mojave Deser , CA (an outreach exercise) with Dr Chris McKay and Ames Education department personnel Brian Day, Barbara Bazar and a accompaning (learning for the the classroom) team of teachers will be studying side-by-side with NASA scientists who search for life in extreme environments, closely approximating what they expect to find on other planets. Why the Mojave -- an inhospitable, sun-drenched spot in the California Desert This natural setting presents scientists with opportunities to study environments that are analogous to what explorers will find on the Moon and Mars. Teachers and scientists will perform scientific fieldwork in lunar geology, Mars astrobiology, Mars geology, and issues of temperature and solar inundation and radiation. for additional information and Outreach projects see http //quest.arc.nasa.gov/

AS16-117-18728 (23 April 1972) --- Astronaut Charles M. Duke Jr., lunar module pilot, exposed this view of the huge Shadow Rock with his 70mm Hasselblad camera during the mission's third and final extravehicular activity (EVA), on April 23, 1972. This particular stop was referenced as Station 13. The scoop, a geological hand tool, leans against the rock and helps to give an idea of the size. Station 13 is a little southeast of North Ray Crater at the Descartes area. While astronauts John W. Young, commander; and Duke descended in the Apollo 16 Lunar Module (LM) Orion to explore the Descartes highlands landing site on the moon, astronaut Thomas K. Mattingly II, command module pilot, remained with the Command and Service Modules (CSM) Casper in lunar orbit.

Small pyrite ammonites in Aptian grey marls. The gray marls around Apt were proposed by Alcide d'Orbigny as a reference for the Aptian stage, for their rich paleontological content. Some thirty different species of ammonites have been recorded in the Tuiliere sections, and belemnite rostrums are abundant in certain levels, as are gastropods and lamellibranchs (oysters and plicatula). These marls also yield corals, sea urchins, brachiopods and shark teeth. The Aptian is the penultimate stratigraphic stage of the Lower Cretaceous. It extends from -121.4 to -113.0 Ma, succeeding the Barremian and preceding the Albian (Secondary or Mesozoic Era). France
