Mars in 3D: James Cameron Convinces NASA to Include 3-D Camera on Mars Rover “Curiosity”

N_ChemCam-Art-cover1 James Cameron, director for the all-time great SciFi blockbuster, smash Avatar, is now helping to direct the search for life on Mars. The AP reports that Cameron has successfully lobbied Charles Bolden, NASA'a administrator, to include a special 3-D camera atop Mars rover "Curiosity." 

The inclusion of a 3-D camera was planned years ago, but was scrapped from the project in 2007 as Jet Propulsion Laboratory (JPL) cut-back due to budget and schedule overruns. Cameron, however, met with Bolden in January, and convinced him that a 3-D camera would gain public interest and help people connect with NASA'a mission to Mars.

Image of the Day: “The Black Widow” Pulsar

B1957_comp_420 

The pulsar, a.k.a. the "Black Widow," is moving through the galaxy at a speed of almost a million kilometers per hour. A bow shock wave due to this motion is visible to optical telescopes, shown in this image as the greenish crescent shape. The pressure behind the bow shock creates a second shock wave that sweeps the cloud of high-energy particles back from the pulsar to form the cocoon.

Could a Major Eruption -Like Katla, Iceland’s “Big One”- Reverse Global Warming?

Advocates of hacking the planet via "geo-engineering" to cool the Earth to offset the effects of greenhouse gases–suggest that major volcanic eruptions such as Iceland's currently quiet Katla Volcano could be the answer. This sounds powerfully like one of those "beware what you wish for" scenarios with profound unintended consequences -economic and otherwise, as Europe just discovered from the eruption of  the Eyjafjallajökull volcano, Katla's interconnected sister.
