Image 1 - Mars Rover Opportunity Spots Mineral Vein Deposited By Water
2011-12-08 04:42:58

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. "This tells a slam-dunk story that water flowed through underground fractures in the rock," said Steve Squyres of Cornell University, Ithaca, N.Y., principal investigator for Opportunity. "This stuff is a fairly pure chemical deposit that formed in place right where we see it....

Dawn Reveals Vesta's 'Color Palette'
2011-12-07 05:46:54

[ Watch the Video ] Vesta appears in a splendid rainbow-colored palette in new images obtained by NASA's Dawn spacecraft. The colors, assigned by scientists to show different rock or mineral types, reveal Vesta to be a world of many varied, well-separated layers and ingredients. Vesta is unique among asteroids visited by spacecraft to date in having such wide variation, supporting the notion that it is transitional between the terrestrial planets -- like Earth, Mercury, Mars and Venus --...

Image 1 - Japanese Devastation The Result Of Merging Waves
2011-12-06 09:57:05

[ Watch the Video ] Researchers from NASA and Ohio State University have discovered that the deadly tsunami generated from the March 2011 Tohoku-Oki earthquake that devastated northeastern Japan resulted from merging waves, causing the killer tsunami to double in intensity over ocean ridges, and then amplifying its power upon landfall. Data taken from NASA and European radar satellites captured at least two wave fronts during the events that day. The fronts merged to form a single, more...

NASA's Voyager 1 spacecraft has entered a new region between our solar system and interstellar space. Data obtained from Voyager over the last year reveal this new region to be a kind of cosmic purgatory. In it, the wind of charged particles streaming out from our sun has calmed, our solar system's magnetic field has piled up, and higher-energy particles from inside our solar system appear to be leaking out into interstellar space. "Voyager tells us now that we're in a stagnation...

NASA's Kepler mission has confirmed its first planet in the "habitable zone," the region where liquid water could exist on a planet´s surface. Kepler also has discovered more than 1,000 new planet candidates, nearly doubling its previously known count. Ten of these candidates are near-Earth-size and orbit in the habitable zone of their host star. Candidates require follow-up observations to verify they are actual planets. The newly confirmed planet, Kepler-22b, is the smallest...

Excellent launch precision for NASA's Mars Science Laboratory mission has forestalled the need for an early trajectory correction maneuver, now not required for a month or more. That first of six planned course adjustments during the 254-day journey from Earth to Mars had originally been scheduled for 15 days after the mission's Nov. 26 launch on a United Launch Alliance Atlas V rocket. Now, the correction maneuver will not be performed until later in December or possibly...

Dawn Provides New 3D Views Of Asteroid Vest
2011-12-02 10:31:47

[ Watch the Video ] Glide over the giant asteroid Vesta with NASA's Dawn spacecraft in a new 3-D video.  Dawn has been orbiting Vesta since July 15, obtaining high-resolution images of its bumpy, cratered surface and making other scientific measurements. The new video is best viewed with red-blue glasses, and incorporates images from Dawn's framing camera from July to August 2011. It was created by Dawn team member Ralf Jaumann of the German Aerospace Center (DLR). The images...

Three NASA Missions Named PopSci's 'Best Of What's New'
2011-11-30 12:22:55

NASA's Dawn, Mars Science Laboratory and MESSENGER missions have earned recognition from Popular Science magazine as innovations worthy of the publication's "Best of What's New" Award in the aviation and space category. Dawn and Mars Science Laboratory are managed by NASA's Jet Propulsion Laboratory in Pasadena, Calif. Dawn is currently orbiting and exploring the massive main-belt asteroid Vesta. The Mars Science Laboratory and its Curiosity rover launched on Nov. 26 on a journey to the...
