Is there life on mars?
A meteorite found in the Sahara, one of the oldest meteorites ever found, gives further evidence to support the theory of extra terrestrial life on mars. The 0.7-pound fragment, NWA 7034, contains more water than any pre-discovered martian meteorites. “It’s about 6,000 parts per million of water,” said Carl B. Agee, director of the institute of Meteoritics, Curator of meteorites and Professor of the department of earth and planetary sciences in New mexico, who led the study. In comparison, there are over 100 martian meteorites discovered, which mostly have 30 times less water content per million. This 320 gram meteorite fragment is currently the most substantial evidence we have of water-based organic life existing on another planet. Using evidence from water molecules locked in the mineral structure, it has been estimated that life could have been supported on mars up to 2 billion years ago. It is suggested that the meteorite exploded from a volcano in the crust of the planet, the water locked in the basalt came from an underground water source near the source of the explosion.
PASADENA, Calif. — NASA’s Curiosity rover mission has found evidence a stream once ran vigorously across the area on Mars where the rover is driving. There is earlier evidence for the presence of water on Mars, but this evidence — images of rocks containing ancient streambed gravels — is the first of its kind.
Scientists are studying the images of stones cemented into a layer of conglomerate rock. The sizes and shapes of stones offer clues to the speed and distance of a long-ago stream’s flow.
“From the size of gravels it carried, we can interpret the water was moving about 3 feet per second, with a depth somewhere between ankle and hip deep,” said Curiosity science co-investigator William Dietrich of the University of California, Berkeley. “Plenty of papers have been written about channels on Mars with many different hypotheses about the flows in them. This is the first time we’re actually seeing water-transported gravel on Mars. This is a transition from speculation about the size of streambed material to direct observation of it.”

The Curiosity rover’s mission to Mars will feed our hunger to know more about the Red Planet, once viewed as home to lost civilizations and canals but now seen as a desert planet that might be colonized. As we await more images and data from Curiosity, illustrated below is what we’ve learned from previous voyages to the fourth planet from the sun.
First Video of Curiosity Rover Shows Its Exciting Descent to Mars
This video covers the last two and a half minutes of Curiosity’s descent from her point of view. It’s made of 297 frames captured during the landing. You can see the thermal shield being jettisoned and the wheel of the rover as it’s being dropped by the skycrane.
There’s a lot of dust at the end, but you get the idea. Spectacular images and awesome success by NASA.
This is a great photo. The newest Mars rover is nearly the size of a Mini Cooper!

NASA’s Curiosity rover and its parachute were spotted by NASA’s Mars Reconnaissance Orbiter as Curiosity descended to the surface on Aug. 5 PDT (Aug. 6 EDT). The High-Resolution Imaging Science Experiment (HiRISE) camera captured this image of Curiosity while the orbiter was listening to transmissions from Curiosity.
Curiosity and its parachute are in the center of the white box; and a separate image is a smaller cutout of MSL stretched to avoid saturation. The rover is landing on the etched plains just north of the sand dunes that fringe “Mt. Sharp.”
But seriously, it’s completely mind-blowing that all of this happened the way it was supposed to. I mean, SKY CRANE.

The biggest rover ever launched to another planet is just one month away from its target: the Red Planet, Mars.
NASA’s huge Curiosity rover is hurtling toward a planned late-night landing on Mars on Aug. 5 PDT (early Aug. 6 EDT), and the anticipation on the science team is high. The reasons are clear: At 1 ton, Curiosity is the largest rover ever aimed at Mars. It will land in a completely new way, using a giant parachute and a rocket-powered sky crane. And it is carrying a sophisticated set of tools to find out if its Martian drop zone could once have been home for life.
But that’s all in the future. First Curiosity has to reach Mars in one piece.
