  • NASA applying space technology to help farmers diagnose fields

    1999April 6, 2011

    An eye in the sky and instruments in the dirt are teamed to help scientists and farmers figure out the best way to nurture crops. At least one preliminary result shows a striking correlation between an image and, two months later, crop yield.

  • What Comes Out of the Top of a Thunderstorm

    1999April 6, 2011

    Scientists studying powerful Gamma-ray Burstsin deep space accidentally discovered a closer source of gamma energy -- thunderclouds on Earth.

  • Solar Cycle Update

    1999April 6, 2011

    Updated predictions from NASA scientists place the solar maximum in mid-2000. As activity on the Sun begins to increase toward this broad maximum, we can expect more auroral displays, radio disruptions and power fluctuations.

  • Adios, Hurricanes

    1999April 6, 2011

    El Nino gets blamed -- rightly or wrongly -- for everything strange in the weather. One NASA scientist has found a relationship: El Nino apparently is related to a reduction in Atlantic hurricane severity.

  • Stepping back to get a closer view

    1999April 6, 2011

    Scientists at the Global Hydrology and Climate Center will use Landsat 7 images along with other data to better understand the phenomenon of urban heat islands.

  • Farewell, Lunar Prospector

    1999April 6, 2011

    NASA's lunar orbiter collided with The MoonSaturday morning, July 31, 1999, at 0952 GMT

  • Destined for a watery grave?

    1999April 6, 2011

    NASA's first mission to The Moonin 25 years could end with a splash next month when ground controllers deliberately crash Lunar Prospector into a crater in search of water.

  • Moon Water Remains a Mystery

    1999April 6, 2011

    The July 31, 1999 crash of Lunar Prospector into The Moondid not liberate detectable signs of water, say scientists. The possibility of water-ice in shadowed lunar craters remains open.

  • The Sun's Sizzling Corona

    1999April 6, 2011

    Scientists continue to ponder one of our star's most closely guarded secrets - why does the solar corona get hotter farther from the Sun's surface?

  • The Case of the Missing Moon Water

    1999April 6, 2011

    Lunar Prospector failed to kick up a visible dust cloud when it crashed into the Moon, but researchers are still sifting through their data for elusive signatures of water.
