NASA will hold a media teleconference at 11 a.m. PST on Wednesday, Dec. 28, to preview twin spacecraft being placed in orbit around the moon on New Year's Eve and New Year's Day. NASA's twin lunar Gravity Recovery and Interior Laboratory (GRAIL) probes were launched from Cape Canaveral Air Force Station on Sept. 10, 2011. GRAIL-A is scheduled to arrive in lunar orbit beginning at 1:21 p.m. PST on Saturday, Dec. 31, and GRAIL-B on Sunday, Jan. 1, beginning at 2:05 p.m. PST. After...

Low Altitude Images Of Vesta Returned By Dawn Spacecraft
2011-12-22 04:31:12

NASA's Dawn spacecraft has sent back the first images of the giant asteroid Vesta from its low-altitude mapping orbit. The images, obtained by the framing camera, show the stippled and lumpy surface in detail never seen before, piquing the curiosity of scientists who are studying Vesta for clues about the solar system's early history. At this detailed resolution, the surface shows abundant small craters, and textures such as small grooves and lineaments that are reminiscent of the...

WASHINGTON, Dec. 19, 2011 /PRNewswire-USNewswire/ -- NASA will host a news teleconference at 1 p.m. EST, Tuesday, Dec. 20, announcing new discoveries by the Kepler mission. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Kepler is the first NASA mission capable of finding Earth-size planets in or near the "habitable zone," the region in a planetary system where liquid water can exist on the surface of an orbiting planet. Although additional observations will be...

Curiosity Rover Begins Research In Space
2011-12-14 04:27:12

NASA's car-sized Curiosity rover has begun monitoring space radiation during its 8-month trip from Earth to Mars. The research will aid in planning for future human missions to the Red Planet. Curiosity launched on Nov. 26 from Cape Canaveral, Fla., aboard the Mars Science Laboratory (MSL). The rover carries an instrument called the Radiation Assessment Detector (RAD) that monitors high-energy atomic and subatomic particles from the sun, distant supernovas and other sources. These...

NASA's Voyager Spacecraft Nears Edge Of The Solar System
2011-12-14 04:17:32

In 1977, Jimmy Carter was sworn in as president, Elvis died, Virginia park ranger Roy Sullivan was hit by lightning a record seventh time, and two NASA space probes destined to turn planetary science on its head launched from Cape Canaveral, Fla. The identical spacecraft, Voyager 1 and Voyager 2, were launched in the summer and programmed to pass by Jupiter and Saturn on different paths. Voyager 2 went on to visit Uranus and Neptune, completing the "Grand Tour of the Solar System," perhaps...

Cassini Captures New Images Of Saturnian Moons
2011-12-13 04:35:07

NASA's Cassini spacecraft successfully completed its closest-ever pass over Saturn's moon Dione on Monday, Dec. 12, slaloming its way through the Saturn system on its way to tomorrow's close flyby of Titan. Cassini is expected to glide about 2,200 miles (3,600 kilometers) over the Titan surface on Dec. 13. In the selection of the raw images obtained during the Cassini Dione flyby, Dione is sometimes joined by other moons. Mimas appears just beyond the dark side of Dione in one view. In...

Image 1 - Dawn Now In Its Lowest Orbit Around Vesta
2011-12-13 04:25:18

NASA's Dawn spacecraft successfully maneuvered into its closest orbit around the giant asteroid Vesta on Monday, Dec. 12, beginning a new phase of science observations. The spacecraft is now circling Vesta at an altitude averaging about 130 miles (210 kilometers) in the phase of the mission known as low altitude mapping orbit. "Dawn has performed some complicated and beautiful choreography in order to reach this lowest orbit," said Marc Rayman, Dawn chief engineer and mission manager based...

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....
