The dust swirls above the highlights of the Martian terrain. Image: High-definition image taking by the HiRISE instrument probe MRO reveals surprising marks on the surface of Mars. By scanning the surface of regular solar modules from Martian rovers, they had the unexpected effect of prolonging the duration of Spirit and Opportunity, which now moves on Mars for nearly 6 years. Dust Devils of the red planet may reach 8 km in height. On Mars, the red dust sucked from the soil consists of sand darker contrasting with the light color of the surface. These frequent air columns begin to rotate and rise under the effect of heat from the Earth's surface. We see mostly in the deserts during heat waves. The dust devils are visible when they raise sufficient amounts of dust. These dust devils are called "eturbules" "in our campaigns. The researchers realized that these were small atmospheric vortices that occur frequently on the red planet. The Martian riddle size, has been resolved. High-definition image taking by the HiRISE instrument probe MRO (Mars Reconnaissance Orbiter) reveals some surprising brands on the soil of Mars.

Image: High definition image taken in February 2008 by the HiRISE instrument probe MRO reveals a surprising avalanche on the soil of Mars. The thaw occurs each spring in the northern hemisphere of Mars, a Martian year, or sidereal period, lasts 686.960 days (1.93 years).Ĭlimate warming causes the melting of ice and carbon dioxide sublimates directly into vapor. The whole scene is illuminated by the Sun than we guess the upper right of the image. The slope has an angle greater than 60 degrees. On the cliff of over 700 meters high in thawing the ice fall on the floor of which rise thick plumes of dust. What caused this sudden avalanche of dust on Mars?ĭigital image shown cons, you can see several layers of white ice and on the right, the rock indicates that the red Martian soil with a mixture of rock and ice.

The probe serves as a network of communication and navigation for the rovers and landers present in soil. She will play the role of high-speed relay for future probes to Mars. The probe, whose scientific objectives are multiple, will select potential landing sites for future missions. The second instrument, the Mars Climate Sounder, which is responsible for scanning the Martian atmosphere above the horizon, meanwhile has problems of timing his field of vision. Half of the sensors of the HiRISE camera (High Resolution Imaging Science Experiment) are indeed abnormal levels of noise but have little impact on image quality. With all this technology onboard, the probe MRO has encountered some difficulties with its instruments. MRO Mars probe from NASA, which actually began its science mission in November 2006, has already sent to Earth in a few months, nearly 8 terabytes of data, as far as MGS ( Mars Global Surveyor) in nine years of observation. On March 10, 2006, after a journey of seven months, it has successfully executed the delicate maneuvers into orbit around Mars. After traveling 500 million km in 7 months to 3 km/s, it was positioned in orbit around Mars. On a total mass of 2180 kg at liftoff, MRO was launched by an Atlas V rocket-401. With a height of 6.50 m and a diameter of 3 m, monster stuffed technology, contains 11 instruments in total to ensure its scientific mission, navigation and communication with Earth (High Resolution Stereo Camera HiRISE, camera CTX context, imaging spectrometer CRISM, MARCI camera, radiometer MCS, SHARAD radar, radio transmitters science.). This probe is much bigger than the previous (Mars Global Surveyor and Mars Odyssey). MRO will identify the best landing sites for probes or men to come and will, upon completion of its scientific mission, communication relay to Earth until 2015. MRO is the fourth artificial satellite in activity of the Red Planet, joining the European probe Mars Express, and the two NASA probes Mars Odyssey and Mars Global Surveyor. probe, launched Friday, Augfrom Cape Canaveral base in Florida, helping to enrich our knowledge about Mars, as the history of its water, its climate or its basement. Mars Reconnaissance Orbiter (MRO) is the name of the eagle eye of a new generation of probes to photograph Mars.
