Weighing The Planets, From Mercury To SaturnBonn, Germany (SPX) Aug 24, 2010 An international research team led by David Champion, now at Max Planck Institute for Radio Astronomy in Bonn, with researchers from Australia, Germany, the U.S., U.K. and Canada, has come up with a new way to weigh the planets in our Solar System, using radio signals from pulsars. Data from a set of four pulsars have been used to weigh Mercury, Venus, Mars, Jupiter and Saturn with their moons and rings. The new measurement technique is sensitive to just 0.003% of the mass of the Earth, and one te ... read more |

Belka and Strelka, the first creatures to return safely to Earth after 24 hours in orbit, live on in the memories of former Soviets, unlike many of their predecessors, who ... more 
Hampton VA (SPX) Aug 20, 2010NASA is developing technologies that will allow landing vehicles to automatically identify and navigate to the location of a safe landing site while detecting landing hazards during the final descent to the surface. This is important because future missions - whether to the Moon, an asteroid, Mars or other location - will need this capability to land safely near specific resources that are ... more

The results provide important clues to the moon's recent geologic and tectonic evolution. The moon formed in a chaotic environment of intense bomba ... more |

Countdown To VestaHuntsville AL (SPX) Aug 20, 2010 Let the countdown begin. NASA's Dawn spacecraft is less than one year away from giant asteroid Vesta. There's nothing more exciting than revealing an unexplored, alien world," says Marc Rayman, Dawn's chief engineer at the Jet Propulsion Laboratory. "Vesta," he predicts, "is going to amaze us." Dawn is slated to enter orbit around Vesta in late July 2011. As the first breathtaking images are beamed back to Earth, researchers will quickly combine them into a movie, allowing us all to ride along. ... read more |
