Model Helps Search For Moon Dust FountainsGreenbelt MD (SPX) Jun 11, 2010 In exploration, sometimes you find more than what you're looking for, including things that shouldn't be there. As the Apollo 17 astronauts orbited over the night side of the moon, with the sun just beneath the horizon right before orbital "sunrise," Eugene Cernan prepared to make observations of sunlight scattered by the sun's thin outer atmosphere and interplanetary dust from comets and collisions between asteroids. The idea was to have the moon block the brilliant direct sunlight so this faint ... read more |

Palo Alto CA (SPX) May 24, 2010Space Systems/Loral (SS/L) has announced its support for NASA's new direction in conjunction with the preliminary design review for the propulsion system that it is building for a spacecraft that will study the lunar atmosphere. "Space Systems/Loral has a long history of working with government agencies to provide industry solutions that meet or exceed mission requirements," said John Cell ... more  
Pasadena CA (JPL) May 21, 2010NASA's Cassini spacecraft is on its way to a flyby of Saturn's largest moon, Titan, after capturing some stunning images of Enceladus. One view shows the hazy outline of Titan behind Saturn's rings, with the dark curve of Enceladus at the bottom. In other images, Enceladus put its craggy face forward, exhibiting some of the fractures and cratering that have made the Saturnian moon a favori ... more 
Pasadena CA (JPL) May 18, 2010About a month and a half after its last double flyby, NASA's Cassini spacecraft will be turning another double play this week, visiting the geyser moon Enceladus and the hazy moon Titan. The alignment of the moons means that Cassini can catch glimpses of these two contrasting worlds within less than 48 hours, with no maneuver in between. Cassini will make its closest approach to Enceladus ... more |

Rock And Roll: Titan's Gem TumblerPasadena CA (JPL) May 13, 2010 It appears flash flooding has paved streambeds in the Xanadu region of Saturn's moon Titan with thousands of sparkling crystal balls of ice, according to scientists with NASA's Cassini spacecraft. By analyzing the way the terrain has scattered radar beams, scientists deduce the spheres measure at least a few centimeters (inches) and maybe up to a couple of meters (yards) in diameter. The spheres likely originated as part of water-ice bedrock in higher terrain in Xanadu. "What we believe happened i ... read more |
