Title Mars Odyssey: Mars' Northern Hemisphere
Abstract NASA's Mars Odyssey detected water ice in the northern hemisphere. During the winter months, the icy soil is covered by a thick layer of carbon dioxide ('dry ice') frost obscuring the water ice signature.This animation is match-framed to #2779 and #2780. Its purpose is to establish a frame of reference using a true color dataset. In this case, that data is from Viking.

Title Mars Odyssey Epithermal Neutron Data overlayed on MGS/MOLA Topography Data (Full Globe, Viking True Color)
Abstract Mars Odyssey's Gamma-ray spectrometer (GRS) instrument has detected large amounts of Hydrogen on Mars, particularly near the south pole. This is an indication that water ice exists in the upper meter of these areas of the Martian surface. The epithermal neutron data ranges from 0 to about 12 counts per second. The blue areas indicate high concentrations of Hydrogen (low epithermal neutron counts). A series of animations was generated to support a Space Science Update (SSU) on the topic. These animations were match-rendered with unsmoothed, smoothed, and Viking true-color data.

Title Valles Marineris: The Grand Canyon of Mars
Explanation The largest canyon in the Solar System [ http://www.nineplanets.org/overview.html ] cuts a wide swath across the face of Mars [ http://www.nineplanets.org/mars.html ]. Named Valles Marineris [ http://astrogeology.usgs.gov/Projects/VallesMarineris/ ], the grand valley extends over 3,000 kilometers long, spans as much as 600 kilometers across, and delves as much as 8 kilometers deep. By comparison, the Earth's Grand Canyon [ http://www.aqd.nps.gov/grd/parks/grca/ ] in Arizona, USA is 800 kilometers long, 30 kilometers across, and 1.8 kilometers deep. The origin of the Valles Marineris [ http://mars.jpl.nasa.gov/mep/science/vm.html ] remains unknown, although a leading hypothesis holds that it started as a crack [ http://antwrp.gsfc.nasa.gov/apod/ap980310.html ] billions of years ago as the planet cooled [ http://helio.estec.esa.nl/intermarsnet/redreport/node20.html ]. Recently [ http://antwrp.gsfc.nasa.gov/apod/ap020531.html ], several geologic processes have been identified in the canyon [ http://www.windows.ucar.edu/cgi-bin/tour.cgi?link=/mars/interior/Valles_Marineris.html&sw=false&sn=4444&d=/mars/interior&edu=mid&br=graphic&back=/mars/exploring/MGS_altimeter_OMons.html&cd=false&tour=&fr=f ].

Candor and Ophir Chasmata
Title Candor and Ophir Chasmata
Explanation First imaged by the Mariner [ http://nssdc.gsfc.nasa.gov/planetary/mars/ mariner.html ] 9 spacecraft, Valles Marineris [ http://antwrp.gsfc.nasa.gov/apod/ap020827.html ], the grand canyon of Mars, is a system of enormous depressions called chasmata that stretch [ http://www.msss.com/mars_images/moc/7_20_98_marineris_rel/ ] some 4,000 kilometers along the Martian equator. Looking north over the canyon's central regions [ http://astrogeology.usgs.gov/Projects/VallesMarineris/ candor_ref.html ], Candor chasma lies in the foreground of this spectacular view [ http://nssdc.gsfc.nasa.gov/imgcat/html/object_page/ vom_nj05s070.html ] with the steep walls of Ophir chasma near the top. Surface collapse and landslides are seen to be part of the complex geologic history of these dramatic features [ http://astrogeology.usgs.gov/Projects/ VallesMarineris/Anaglyph/mars_anaglyph.html ] but recent high resolution [ http://antwrp.gsfc.nasa.gov/apod/ap980319.html ] images have also revealed layered deposits [ http://antwrp.gsfc.nasa.gov/apod/ap001205.html ] within the canyon system. This picture represents a mosaic of images recorded in 1978 from Martian orbit by the Viking [ http://history.nasa.gov/SP-4212/on-mars.html ] 1 and 2 spacecraft. The full width of the picture covers about 800 kilometers.
Five to Mars
Title Five to Mars
Explanation Come December 2003 - January 2004, an armada of five new invaders [ http://www.planetary.org/rrgtm/missions5.html ] from Earth should arrive on the shores of the Red Planet -- the Japanese ( ISAS [ http://www.isas.ac.jp/ ]) Nozomi [ http://www.isas.ac.jp/e/enterp/missions/nozomi/ index.html ] orbiter, the European Space Agency's Mars Express [ http://sci.esa.int/home/marsexpress/ ] orbiter carrying the Beagle 2 [ http://www.beagle2.com/index.htm ] lander, and NASA's own two Mars Exploration [ http://mars.jpl.nasa.gov/mer/ ] Rovers. While Nozomi began [ http://antwrp.gsfc.nasa.gov/apod/ap980904.html ] its interplanetary voyage in 1998, the other spacecraft are scheduled for launch windows beginning this June. Clearly, earthdwellers remain intensely curious about Mars and the tantalizing [ http://antwrp.gsfc.nasa.gov/apod/ap030221.html ] possibility of past or present martian life [ http://cmex-www.arc.nasa.gov/SiteCat/sitecat2/ stratex.htm ], with these robotic missions focussing on investigating the planet's atmosphere and the search for water [ http://www.psrd.hawaii.edu/Sept98/GusevMars.html ]. This mosaic [ http://nssdc.gsfc.nasa.gov/photo_gallery/caption/ marsglobe2.txt ] of over 100 Viking 1 orbiter images of Mars [ http://nssdc.gsfc.nasa.gov/photo_gallery/ photogallery-mars.html ] was recorded in 1980 and is projected to show the perspective seen from an approaching spacecraft at a distance of 2,000 kilometers. Exceptional [ http://skyandtelescope.com/observing/objects/planets/ article_929_1.asp ] views of Mars will be possible from earthbound telescopes in August and September.
Close Up Fly Over of Mars Po …
Title Close Up Fly Over of Mars Polar Lander Landing Area in True Color
Abstract This is one of a series of visualizations showing false-colored renderings of the Martian topography measured by MOLA in the vicinity of the Mars Polar Lander landing site. Blue tones represent elevations of less than 2 kilometers, while reddish tones are greater than about 2.8 kilometers, relative to the mean equatorial height of Mars. The elevation of the landing site is about 2.4 km, midway into the polar layered terrain. The 400 meters (1/4 mile) resolution of the MOLA data gives a smoothed but vertically exaggerated view of the topography. At this scale it is impossible to ascertain the actual roughness at the lander's destination, forcing project directors to make their best guesses based on available data.

Could Hydrogen Peroxide Life …
Title Could Hydrogen Peroxide Life Survive on Mars?
Explanation Is there life on Mars? Although no unambiguous evidence for indigenous life on Mars has ever been found, a more speculative question -- "could" some life forms survive on Mars -- has taken on a new twist. Two planetary scientists recently speculated [ http://www.cosis.net/abstracts/EPSC2007/00439/EPSC2007-J-00439.pdf ] that were extremophile microbes [ http://antwrp.gsfc.nasa.gov/apod/ap060122.html ] to involve a mixture of hydrogen peroxide [ http://en.wikipedia.org/wiki/Hydrogen_peroxide ] (H2O2) and water (H2O), these microbes might well be able survive the thin, cold, dry atmosphere on Mars. Life [ http://www.hlasek.com/brachinus_crepitans_2053.html ] that involves hydrogen peroxide [ http://www.h2o2.com/intro/faq.html ] does exist here on Earth [ http://antwrp.gsfc.nasa.gov/apod/ap070325.html ], they note, and such life would be better able to absorb water on Mars [ http://en.wikipedia.org/wiki/Mars ]. They also claim that such life [ http://www.planetary.org/blog/article/00001109/ ] would be consistent with the ambiguous results coming out from the life-detecting experiments [ http://www.daviddarling.info/encyclopedia/V/VikingGCMS.html ] aboard the old Viking Landers [ http://www.nasm.si.edu/exhibitions/GAL100/viking.html ]. Although such speculation is not definitive, debating possibilities for life on Mars [ http://antwrp.gsfc.nasa.gov/apod/ap960207.html ] has again proven to be fun and a magnet for media attention. Pictured above [ http://photojournal.jpl.nasa.gov/catalog/PIA00571 ], the Viking Lander 2 [ http://en.wikipedia.org/wiki/Viking_2 ] captured an unusual image of the Martian surface [ http://www.google.com/mars/ ] in 1979 sporting a thin layer of seasonal water ice [ http://www.howstuffworks.com/ice-rink.htm ].
Mars: Just The Facts
Title Mars: Just The Facts
Explanation Mars [ http://www.challenger.org/marsl.html ], the freeze-dried planet [ http://nssdc.gsfc.nasa.gov/planetary/factsheet/marsfact.html ], orbits 137 million miles from the Sun or at about 1.5 times the Earth-Sun distance [ http://antwrp.gsfc.nasa.gov/apod/ap960727.html ]. It has two diminutive moons [ http://antwrp.gsfc.nasa.gov/apod/ap961222.html ], towering extinct volcanos [ http://antwrp.gsfc.nasa.gov/apod/ap950719.html ], an immense canyon system [ http://antwrp.gsfc.nasa.gov/apod/ap950720.html ], a thin atmosphere chiefly composed of carbon dioxide (CO2), a frigid average surface temperature of -63 degrees Celsius [ http://www.unidata.ucar.edu/staff/blynds/tmp.html ], and permanent frozen CO2 polar caps which contain some water ice. Mars' surface presently lacks liquid water [ http://antwrp.gsfc.nasa.gov/apod/ap970316.html ] and has a reddish color because of an abundance of oxidized iron compounds (rust). A small terrestrial planet [ http://www.seds.org/nineplanets/nineplanets/mars.html ], fourth from the Sun [ http://antwrp.gsfc.nasa.gov/apod/ap970528.html ], Mars has only about 3/8 the surface gravity of Earth. So for example, if you tip the scale at a hefty 200 pounds on Earth you'd be a 75 pound featherweight on Mars [ http://quest.arc.nasa.gov/mars/ ]. The low martian gravity will be good for NASA's Mars Pathfinder [ http://mpfwww.jpl.nasa.gov/ ] spacecraft scheduled to land on Mars [ http://bang.lanl.gov/solarsys/mars.htm ] next Friday, July 4th [ http://www.lpl.arizona.edu/imp/mission.success.html ]. Using rockets, parachutes, and airbags [ http://mars.sgi.com/mpf/realtime/edlpage.html ], Mars Pathfinder [ http://mpfwww.arc.nasa.gov/mpf/mission_ops.html ] will be the first spacecraft to touchdown on the planet since the Viking landers [ http://antwrp.gsfc.nasa.gov/apod/ap960722.html ] in 1976. Pathfinder is also scheduled to begin the first ever mobile surface exploration [ http://cmex-www.arc.nasa.gov/ ] by releasing the robot rover [ http://ranier.hq.nasa.gov/telerobotics_page/coolrobots96.html ], "Mars Sojourner" [ http://mars.sgi.com/rover/about.html ].
The Face on Mars
Title The Face on Mars
Explanation This image, showing what looks to be a human face sculpted on the martian surface, was produced using data from NASA's Viking 1 orbiter [ http://nssdc.gsfc.nasa.gov/planetary/viking.html ] in 1976. Described in a press release as a "face-like hill" it caused some to offer the sensational speculation that it was an artificial construct built by an intelligent civilization on Mars! As a result, this image was splashed across the covers of many grocery store tabloids at the time. A detailed analysis of multiple images of this feature reveals a natural looking martian hill whose illusory face-like appearance depends on viewing angle and angle of illumination. For more information about the picture see the NSSDC Photo Gallery of Mars. [ http://nssdc.gsfc.nasa.gov/photo_gallery/PhotoGallery-Mars.html#controversy ] For a detailed discussion of the "Face on Mars" see Calvin J. Hamilton's Face on Mars page.

Title 25 Years Ago: Vikings on Mars
Explanation On July 20, 1976 [ http://science.nasa.gov/headlines/y2001/ast20jul_1.htm ], NASA's Viking 1 lander became the first [ http://www.star.le.ac.uk/edu/solar/sovmars.html ] U.S. spacecraft to land on Mars [ http://cmex-www.arc.nasa.gov/ ], followed weeks later by its twin robot explorer, the Viking 2 lander. Operating [ http://photojournal.jpl.nasa.gov/cgi-bin/ PIAGenCatalogPage.pl?PIA00563 ] on the Martian surface [ http://nssdc.gsfc.nasa.gov/photo_gallery/ photogallery-mars.html#surface ] into the early 1980s, the Vikings took [ http://history.nasa.gov/SP-425/cover.htm ] thousands of pictures, conducted [ http://nssdc.gsfc.nasa.gov/planetary/viking.html ] sophisticated chemical searches for life [ http://history.nasa.gov/SP-4212/ch11-6.html ], and studied the martian weather [ http://www-k12.atmos.washington.edu/k12/resources/ mars_data-information/mars_overview.html ] and geology. In the dramatically detailed image above, a field of rocks and boulders is viewed from the Viking 1 landing site on Chryse Planitia (the Plain of Chryse). Viking 1's dusty foot pad is just visible at the lower right. The image was created [ http://nssdc.gsfc.nasa.gov/photo_gallery/caption/ vikinglander1-2.txt ] by combining high resolution black and white images with lower resolution color images of the same area. NASA is continuing its well chronicled [ http://history.nasa.gov/SP-4212/on-mars.html ] martian exploration program as the Mars Odyssey [ http://mars.jpl.nasa.gov/odyssey/ ] spacecraft is scheduled to arrive at the mysterious [ http://antwrp.gsfc.nasa.gov/apod/ap970528.html ] Red Planet on October 24th.
