Engineers Diagnosing Voyager 2 Data SystemPasadena CA (JPL) May 10, 2010 Engineers have shifted NASA's Voyager 2 spacecraft into a mode that transmits only spacecraft health and status data while they diagnose an unexpected change in the pattern of returning data. Preliminary engineering data received on May 1 show the spacecraft is basically healthy, and that the source of the issue is the flight data system, which is responsible for formatting the data to send back to Earth. The change in the data return pattern has prevented mission managers from decoding science da ... read more |

Knoxville TN (SPX) Apr 29, 2010Asteroids may not be the dark, dry, lifeless chunks of rock scientists have long thought. Josh Emery, research assistant professor with the earth and planetary sciences department at the University of Tennessee, Knoxville, has found evidence of water ice and organic material on the asteroid 24 Themis. This evidence supports the idea that asteroids could be responsible for bringing water an ... more |

SDO Observes Massive Eruption And Scorching RainHuntsville AL (SPX) Apr 28, 2010 Just last week, scientists working with NASA's new Solar Dynamics Observatory (SDO) released the most astonishing movies of the sun anyone had ever seen. Now, they're doing it again. "SDO has just observed a massive eruption on the sun-one of the biggest in years," says Lika Guhathakurta of NASA headquarters in Washington DC. "The footage is not only dramatic, but also could solve a longstanding mystery of solar physics." Karel Schrijver of Lockheed Martin's Solar and Astrophysics Lab is lea ... read more |
