PASADENA, Calif., Dec. 11 /PRNewswire-USNewswire/ -- NASA's Mars Reconnaissance Orbiter has completed its primary, two-year science phase. The spacecraft has found signs of a complex Martian history of climate change that produced a diversity of past watery environments. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) The orbiter has returned 73 terabits of science data, more than all earlier Mars missions combined. The spacecraft will build on this record as it continues to...

NASA's Mars Reconnaissance Orbiter has completed its primary, two-year science phase. The spacecraft has found signs of a complex Martian history of climate change that produced a diversity of past watery environments. The orbiter has returned 73 terabits of science data, more than all earlier Mars missions combined. The spacecraft will build on this record as it continues to examine Mars in unprecedented detail during its next two-year phase of science operations. Among the major findings...

As much as a third of Mars could have been underwater, UA scientists say An international team of scientists who analyzed data from the Gamma Ray Spectrometer onboard NASA's Mars Odyssey reports new evidence for the controversial idea that oceans once covered about a third of ancient Mars. "We compared Gamma Ray Spectrometer data on potassium, thorium and iron above and below a shoreline believed to mark an ancient ocean that covered a third of Mars' surface, and an inner shoreline believed...

The longest-serving of six spacecraft now studying Mars is up to new tricks for a third two-year extension of its mission to examine the most Earthlike of known foreign planets. NASA's Mars Odyssey is altering its orbit to gain even better sensitivity for its infrared mapping of Martian minerals. During the mission extension through September 2010, it will also point its camera with more flexibility than it has ever used before. Odyssey reached Mars in 2001. The orbit adjustment will allow...

Scientists leading NASA's Phoenix Mars mission from the University of Arizona in Tucson sent commands to unstow its robotic arm and take more images of its landing site early today. The Phoenix lander sent back new sharp color images from Mars late yesterday. Phoenix imaging scientists made a color mosaic of images taken by the lander's Surface Stereo Imager on landing day, May 25, and the first two full "sols," or Martian days, after landing. The panorama, now about one-third complete,...

A NASA spacecraft today sent pictures showing itself in good condition after making the first successful landing in a polar region of Mars. The images from NASA's Mars Phoenix Lander also provided a glimpse of the flat valley floor expected to have water-rich permafrost within reach of the lander's robotic arm. The landing ends a 422-million-mile journey from Earth and begins a three-month mission that will use instruments to taste and sniff the northern polar site's soil and ice. "We see...

This story was updated at 1:33 p.m. EDT. WASHINGTON — With just 12 days to go until its Mars arrival, NASA's Phoenix lander is functioning well and on course to be the first mission to land in the frigid, arctic regions of the red planet, NASA officials said today. A planned maneuver to adjust Phoenix's course was canceled last Saturday because the spacecraft is on track for its May 25 landing, said Barry Goldstein, Phoenix project manager at NASA's Jet Propulsion...

Three Mars spacecraft are adjusting their orbits to be over the right place at the right time to listen to NASA's Phoenix Mars Lander as it enters the Martian atmosphere on May 25. Every landing on Mars is difficult. Having three orbiters track Phoenix as it streaks through Mars' atmosphere will set a new standard for coverage of critical events during a robotic landing. The data stream from Phoenix will be relayed to Earth throughout the spacecraft's entry, descent and landing events. If...

LOS ANGELES -- A three-legged NASA spacecraft with a long arm for digging trenches is going to the Martian north pole to study if the environment is favorable for primitive life. But before it can start its work, the Phoenix Mars Lander must survive landing on the surface of the rocky, dusty Red Planet, which has a reputation of swallowing manmade probes. Of the 15 global attempts to land spacecraft on Mars, only five have made it. "Mars has the tendency to throw you curve balls," said...

Every day for the past decade, the U.S. has had a presence at Mars, using spacecraft to understand this extreme world and its potential as a past or present habitat for life. During that time, all spacecraft have become virtually incommunicado for about two weeks every two years. The reason is solar conjunction, which occurs again from October 18-29, 2006. Solar conjunction is the period when Earth and Mars, in their eternal march around the Sun, are obscured from each other by the fiery orb...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
