Stereo Saturn |
| Explanation |
Get out your red/blue glasses [ http://img.arc.nasa.gov/archive/desert96/redblue.html ] and launch [ http://antwrp.gsfc.nasa.gov/apod/ap971016.html ] yourself into this stereo [ http://cass.jsc.nasa.gov/research/stereo_atlas/SS3D.HTM ] picture of Saturn! The picture is actually composed from two images recorded weeks apart by the Voyager 2 spacecraft [ http://vraptor.jpl.nasa.gov/voyager/voyager_fs.html ] during its visit to [ http://nssdc.gsfc.nasa.gov/planetary/voyager.html ] the Saturnian System in August of 1981. Traveling at about 35,000 miles per hour, the spacecraft's changing viewpoint from one image to the next produced this exaggerated but pleasing stereo effect [ http://antwrp.gsfc.nasa.gov/apod/ap970404.html ]. Saturn is the second largest planet [ http://seds.lpl.arizona.edu/nineplanets/nineplanets/saturn.html ] in the Solar System, after Jupiter. Its spectacular ring system [ http://ringmaster.arc.nasa.gov/saturn/saturn.html ] is so wide that it would span the space between the Earth and Moon. Although they look solid here, Saturn's [ http://antwrp.gsfc.nasa.gov/apod/ap000129.html ] rings consist of individually orbiting bits of ice and rock ranging in size from grains of sand to barn-sized boulders. |

Newton Crater: Evidence for Recent Water on Mars |
| Explanation |
What could have formed these unusual channels? Inside a small crater [ http://www.jpl.nasa.gov/galileo/sepo/education/plansurf/plansurfii.html ] that lies inside large Newton Crater [ http://ic.arc.nasa.gov/ic/projects/bayes-group/Atlas/Mars/features/n/newton.html ] on Mars [ http://www.seds.org/nineplanets/nineplanets/mars.html ], numerous narrow channels run from the top down to the crater floor. The above picture [ http://www.msss.com/mars_images/moc/june2000/newton/index.html ] covers a region spanning about 3000 meters across. These and other gullies [ http://antwrp.gsfc.nasa.gov/apod/ap000623.html ] have been found on Mars in recent high-resolution pictures [ http://www.msss.com/mars_images/moc/june2000/index.html ] taken by the orbiting Mars Global Surveyor [ http://mars.jpl.nasa.gov/mgs/overvu/overview.html ] robot spacecraft. Similar channels on Earth [ http://www.msss.com/mars_images/moc/june2000/labeled/index.html ] are formed by flowing water, but on Mars the temperature is normally too cold and the atmosphere [ http://windows.ivv.nasa.gov/cgi-bin/tour_def/mars/lower_atmosphere.html ] too thin to sustain liquid water [ http://www.es.mq.edu.au/courses/GEOS112/mod2/worsho/06/6_2.html ]. Nevertheless, many scientists now hypothesize that liquid water did burst out here from underground Mars [ http://antwrp.gsfc.nasa.gov/apod/mars.html ], eroded the gullies, and pooled at the bottom as it froze and evaporated. If so, life-sustaining ice and water [ http://antwrp.gsfc.nasa.gov/apod/ap980530.html ] might exist even today below the Martian surface [ http://antwrp.gsfc.nasa.gov/apod/ap000514.html ] -- water that could potentially support a human mission to Mars [ http://www-sn.jsc.nasa.gov/marsref/contents.html ]. Research into this exciting possibility [ http://www.sciencemag.org/feature/data/hottopics/index.html ] is sure to continue! |

Mercury Astronauts and a Redstone |
| Explanation |
Space suited project Mercury [ http://www.ksc.nasa.gov/history/mercury/mercury.html ] astronauts John H. Glenn [ http://politicsusa.com/PoliticsUSA/resources/almanac/ohs1.html.cgi ], Virgil I. Grissom [ http://repos.msfc.nasa.gov/history/mm/grisbio.html ], and Alan B. Shepard Jr. [ http://repos.msfc.nasa.gov/history/mm/shepbio.html ] (left to right) are pictured here posing in front of a Redstone rocket [ http://www.redstone.army.mil/history/pioneer.html ] in this 1961 NASA publicity photo. Project Mercury [ http://www.osf.hq.nasa.gov/mercury/ ] was the first U.S. program designed to put humans in space. It resulted in 6 manned flights using one-man capsules and Redstone and Atlas rockets. Shortly after the first U.S. manned flight on May 5, 1961, a suborbital flight piloted by Alan Shepard, President Kennedy announced the goal of a manned lunar landing by 1970. This goal was achieved by NASA's Apollo program [ http://bang.lanl.gov/solarsys/apo14.htm ] and Shepard himself walked on the moon as a member of the Apollo 14 [ http://antwrp.gsfc.nasa.gov/apod/ap951209.html ] mission. |
