Mars rover team members have begun informally naming features around the rim of Endeavour Crater, as they develop plans to investigate that destination when NASA's Opportunity rover arrives there after many more months of driving. A new, super-resolution view of a portion of Endeavour's rim reveals details that were not discernible in earlier images from the rover. Several high points along the rim can be correlated with points discernible from orbit. Super-resolution is an imaging technique...

When some Mars explorers learned of plans for a worldwide photography event combining shots taken from thousands of different locations on May 2, 2010, they figured, "Why just one world?" A New York Times photography blog, Lens, proposed the event and has received more than 12,000 images from around the world. Plus one from a rover on Mars. The inspiration came from a suggestion by Emily Lakdawalla, science and technology coordinator for The Planetary Society in Pasadena, Calif. Astronomer...

NASA's Mars Exploration Rover Opportunity has captured a new view of the rim of Endeavour crater, the rover's destination in a multi-year traverse along the sandy Martian landscape. A portion of the rim about 13 kilometers (8 miles) away appears on the horizon at the left edge of the image, along with the rim of an even more distant crater, Iazu, on the right. Endeavour is 21 kilometers (13 miles) in diameter, about 25 times wider than Victoria crater, the last major crater Opportunity...

New studies of ripples and dunes shaped by the winds on Mars testify to variability on that planet, identifying at least one place where ripples are actively migrating and another where the ripples have been stationary for 100,000 years or more. Patterns of dunes and the smaller ripples present some of the more visually striking landforms photographed by cameras orbiting Mars.  Investigations of whether they are moving go back more than a decade. Two reports presented at the 41st Lunar...

The U.S. space agency says its Mars rover Opportunity has recorded environmental changes that occurred during billions of years at a Martian crater. Opportunity surveyed Victoria Crater September 2006 through August 2008. The National Aeronautics and Space Administration said findings from that work reinforce and expand what researchers learned from Opportunity's exploration of two smaller craters after landing on Mars in 2004. The rover revealed the effects of wind and water, NASA said, with...

The U.S. space agency says its Mars rover Opportunity is within sight of the horizon of the big crater toward which it has been traveling for six months. The National Aeronautics and Space Administration said Endeavour Crater, 14 miles in diameter, is still 7 miles from Opportunity as the crow flies and at least 30 percent farther away on routes mapped for evading en route hazards. NASA scientists said Opportunity has driven about 2 miles since it climbed out of Victoria Crater last August...

Engineers from NASA's Jet Propulsion Laboratory and students at the California Institute of Technology have designed and tested a versatile, low-mass robot that can rappel off cliffs, travel nimbly over steep and rocky terrain, and explore deep craters. This prototype rover, called Axel, might help future robotic spacecraft better explore and investigate foreign worlds such as Mars. On Earth, Axel might assist in search-and-rescue operations. "Axel extends our ability to explore terrains that...

The Teide volcanic peak on the island of Tenerife acted as a mock-up of the Moon landscape last week, with eight European student teams tuning, testing and driving their lunar rovers in preparation for a robotics competition that took place during the dark nights of last weekend. Roving on the Moon is not easy. Lunar robotic explorers have to travel in a vacuum, over rough and steep terrain covered by crust and dust. The Sun heats the rovers up to 110°C and, when driving into a...

NASA's Mars Rover Opportunity is setting its sights on a crater more than 20 times larger than its home for the past two years. To reach the crater the rover team calls Endeavour, Opportunity would need to drive approximately 7 miles to the southeast, matching the total distance it has traveled since landing on Mars in early 2004. The rover climbed out of Victoria Crater earlier this month. "We may not get there, but it is scientifically the right direction to go anyway," said Steve Squyres...

NASA's Mars Exploration Rover Opportunity has climbed out of the large crater that it had been examining from the inside since last September. "The rover is back on flat ground," an engineer who drives it, Paolo Bellutta of NASA's Jet Propulsion Laboratory, announced to the mission's international team of scientists and engineers. Opportunity used its own entry tracks from nearly a year ago as the path for a drive of 6.8 meters (22 feet) bringing the rover out over the top of the inner slope...

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...
