Mars Rover Spots Clouds Shaped by Gravity Waves. 22 Shares AP Photo/NASA/JPL-Caltech/Texas A&M/Cornell University NASA's Curiosity rover usually keeps its instruments firmly focused on Mars's ground, zapping grit with its laser or drilling cores in bedrock.

Mars Rover Spots Clouds Shaped by Gravity Waves

But every few days, the SUV-sized robot, like any good dreamer, shifts its sights upward to the clouds. Well into its fifth year, the rover has now shot more than 500 movies of the clouds above it, including the first ground-based view of martian clouds shaped by gravity waves, researchers reported here this week at the Lunar and Planetary Science Conference.

Rough Road Ahead: Rocky Mars Terrain Challenges Curiosity Rover. The Curiosity rover's wheels have taken a beating thus far on Mars, and the road ahead may be even rockier.

Rough Road Ahead: Rocky Mars Terrain Challenges Curiosity Rover

The 1-ton robot has just crossed out of its landing ellipse — the 12- by 4-mile (19 by 7 kilometers) zone that was targeted for its dramatic August 2012 touchdown — and is now moving toward an increasingly challenging landscape called the Zabriskie Plateau, mission team members said. "We are heading out into very rough terrain," Curiosity project scientist John Grotzinger, a geologist at the California Institute of Technology in Pasadena, said during a presentation at the 8th International Conference on Mars, which took place at Caltech last week. "These rocks have been a problem for us. " [Amazing Mars Rover Curiosity's Martian Views (Latest Photos)] Curiosity embarked last July on a roughly 5-mile (8 km) drive to the base of Mount Sharp, which has long been its ultimate science destination.

"The wind becomes a big problem for our wheels," Grotzinger said. Soviet spacecraft possibly spotted on Mars. LOS ANGELES (AP) — Space fans from Russia scanning NASA images have spotted what may be a Soviet spacecraft that landed on Mars in 1971 and then mysteriously stopped working.

Soviet spacecraft possibly spotted on Mars

Photos taken by NASA’s Mars Reconnaissance Orbiter circling the red planet pointed to what may be the Mars 3 lander along with its parachute, heat shield and other hardware that it jettisoned during the descent through the thin Martian atmosphere. While scientists said the find appeared promising, more follow-up was needed to rule out other possibilities. Mars 3 operated for only 15 seconds on the Martian surface before it suddenly stopped communicating. It was part of a double mission the Soviet Union launched in 1971. Its twin, Mars 2, crashed.

The Russian space enthusiasts were part of an online group that followed the Curiosity rover, NASA’s latest Mars mission. There are future plans to take more pictures and talk to Russian engineers about the mission to get a better idea of the landing process. Another Weird Shiny Thing on Mars.

That, anyway, is the leading explanation. We'll have to keep looking. A 2006 letter in Nature described this idea of geysers near the Martian south pole. Image of the Day. Amazing Mars Rover Curiosity's Latest Photos. 'Mars Flower' Photo Puzzles Scientists. An odd flower-like feature spotted on Mars by NASA's Curiosity rover continues to perplex researchers, who nevertheless stress that its origins are not biological.

'Mars Flower' Photo Puzzles Scientists

The object garnered a lot of attention after Curiosity photographed it last month, with many Internet users quickly dubbing it the "Mars flower. " The feature is actually a rounded, light-colored pebble slightly larger than a grain of sand, but determining its precise mineralogical makeup would require more information, researchers said. "It could be a lot of things, but without some chemical information to back me up, I'd really hesitate to say what it is," Aileen Yingst, of the Planetary Science Institute in Tucson, Ariz., told reporters today (Jan. 15). "I'm not trying to be cagey," added Yingst, the deputy principal investigator for Curiosity's Mars Hand Lens Imager, or MAHLI. Images of Mars from NASA’s Spirit & Opportunity Exploration Rovers.
