Evidence of Ancient Water Discovered at Mars Crater
2012-05-04 04:26:16

NASA's Mars Exploration Rover Opportunity discovered evidence of ancient water at the rim of an ancient impact crater on the planet's surface, according to a new report published in the May 4 edition of the journal Science. The rover, which completed its original three-month mission eight years ago and reached the 4 billion year old Endeavour crater last summer, found evidence that the impact that had originally created the crater released heated, underground water that had deposited zinc...

Image 1 - Mars Rover Curiosity Carries A Penny For Camera Checkup

The camera at the end of the robotic arm on NASA's Mars rover Curiosity has its own calibration target, a smartphone-size plaque that looks like an eye chart supplemented with color chips and an attached penny. When Curiosity lands on Mars in August, researchers will use this calibration target to test performance of the rover's Mars Hand Lens Imager, or MAHLI. MAHLI's close-up inspections of Martian rocks and soil will show details so tiny, the calibration target includes reference lines...

WASHINGTON, Dec. 7, 2011 /PRNewswire-USNewswire/ -- NASA's Mars Exploration Rover Opportunity has found bright veins of a mineral, apparently gypsum, deposited by water. Analysis of the vein will help improve understanding of the history of wet environments on Mars.

Ancient Lake Delta Found On Mars
2011-09-02 11:36:31

  The European Space Agency (ESA) said on Friday that it has discovered a crater on Mars that was once filled by a lake. NASA's Mars Global Surveyor spacecraft was first to identify the lake.  ESA said this delta structure is characteristic of the presence of a lake in the crater. The delta is an ancient fan-shaped deposit of dark sediments that is laid down in water, according to the space agency. The extinct lake is in the 40-mile-diameter Eberswalde crater that formed...

WASHINGTON, Sept. 1, 2011 /PRNewswire-USNewswire/ -- The initial work of NASA's Mars rover Opportunity at its new location on Mars shows surface compositional differences from anything the robot has studied in its first 7.5 years of exploration. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Opportunity arrived three weeks ago at the rim of a 14-mile-wide (22-kilometer-wide) crater named Endeavour. The first rock it examined is flat-topped and about the size of a footstool....

NASA said on Wednesday that its Mars Exploration Rover Opportunity has reached the planet's Endeavour Crater after a three year journey. The rover relayed its arrival at a location named Spirit Point on the crater's rim. NASA selected "Spirit Point" as an informal name for the site to commemorate Opportunity's rover twin, Spirit, which ended communication and finished its mission earlier this year. Opportunity has driven roughly 13 miles since climbing out of the Victoria crater. "NASA is...

NASA's Mars Exploration Rover Opportunity is poised to reach the rim of a large crater, beginning a new phase of research for the rover. Opportunity drove out of Victoria crater in August 2008, and now only 2 miles stand in its way of driving out of Endeavour crater. NASA selected "Spirit Point" as an informal name for the site on the rim where Opportunity will arrive at the Endeavour crater. The choice commemorates Opportunity's rover twin, Spirit, which ended communication and finished...

A drive of 482 feet (146.8 meters) on June 1, 2011, took NASA's Mars Exploration Rover Opportunity past 30 kilometers (18.64 miles) in total odometry during 88 months of driving on Mars. That's 50 times the distance originally planned for the mission and more than 12 times the distance racehorses will run next week at the Belmont Stakes. Opportunity has passed many craters on its crater-hopping tour. One of the youngest of them is "Skylab" crater, which the rover passed last month. Rocks...

On Dec. 16, 2010, NASA's Mars Exploration Rover Opportunity reached a crater about the size of a football field-some 90 meters (295 feet) in diameter. The rover team plans to use cameras and spectrometers during the next several weeks to examine rocks exposed at the crater, informally named "Santa Maria." A mosaic of image frames taken by Opportunity's navigation camera on Dec. 16 shows the crater's sharp rim and rocks ejected from the impact that had excavated the crater. Opportunity...

A newly installed webcam is giving the public an opportunity to watch technicians assemble and test the next NASA Mars rover, one of the most technologically challenging interplanetary missions ever designed. NASA's Mars Science Laboratory, also known as the Curiosity rover, is in a clean room at the agency's Jet Propulsion Laboratory in Pasadena, Calif. The webcam, affectionately called "Curiosity Cam," provides the video feed, without audio, from a viewing gallery above the clean room...

Hematite (AE) or haematite (BE) is the mineral form of Iron (III) oxide, (Fe2O3), one of several iron oxides. The ore sometimes contains slight amounts of titanium. When shaped into ornaments, it is often called black diamond. Hematite is a very common mineral, coloured black to steel or silver-gray, brown to reddish brown, or red. It is mined as the main ore of iron. Varieties include Bloodstone, Iron Rose, Kidney Ore, Martite, Paint Ore, Specularite (Specular Hematite), Rainbow Hematite...
