Since April 23rd, NASA Mars exploration rover Spirit as been lodged in a site on Mars scientists call “Troy”. Beginning on November 16th, NASA will begin transmitting commands to Spirit as part of an escape plan to free the venerable robot from its Martian sand trap.
NASA's Mars Reconnaissance Orbiter has revealed frozen water hiding just below the surface of mid-latitude Mars. The spacecraft's observations were obtained from orbit after meteorites excavated fresh craters on the Red Planet.
Scientists controlling instruments on the orbiter found bright ice exposed at five Martian sites with new craters that range in depth from approximately 1.5 feet to 8 feet. The craters did not exist in earlier images of the same sites. Some of the craters show a thin layer of bright ice atop darker underlying material.
NASA's Mars Rover Opportunity is investigating a metallic meteorite the size of a large watermelon that is providing researchers more details about the Red Planet's environmental history.
The rock, dubbed "Block Island," is larger than any other known meteorite on Mars. Scientists calculate it is too massive to have hit the ground without disintegrating unless Mars had a much thicker atmosphere than it has now when the rock fell. Atmosphere slows the descent of meteorites. Additional studies also may provide clues about how weathering has affected the rock since it fell.
WASHINGTON -- NASA's Mars Science Laboratory rover, scheduled for launch in 2011, has a new name thanks to a sixth-grade student from Kansas. Twelve-year-old Clara Ma from the Sunflower Elementary school in Lenexa submitted the winning entry, "Curiosity." As her prize, Ma wins a trip to NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif., where she will be invited to sign her name directly onto the rover as it is being assembled.
A NASA panel selected the name following a nationwide student contest that attracted more than 9,000 proposals via the Internet and mail.
