  1. NASA Looks a Hurricane's Temperature in the Eye April 30, 2002

    Last year, NASA researchers took the temperature of the eye of Hurricane Erin to determine how a hurricane's warm center fuels the strength of storms.

  2. Finding Tiny Particles in Hurricanes May Help with Predictions April 29, 2002

    NASA-funded scientists are looking at microscopic ice particles inside hurricanes to determine if they contribute to the storm's strengthening or weakening.

  3. NASA's Aqua Spacecraft to Study Earth's Water Cycle April 23, 2002

    NASA's mission to understand and protect our home planet will mark a major milestone this spring with the launch of the Aqua satellite.

  4. Massive Icebergs May Affect Antarctic Sea Life and Food Chain April 22, 2002

    NASA-funded research using satellite data has shown large icebergs that have broken off from Antarctica's Ross Ice Shelf are dramatically affecting the growth of minute plant life in the ocean around the region -- plant life vital to the local food chain.

  5. An Earth Day Present From Space: Europe and Asia's Watery Gateway April 22, 2002

    Taken by NASA's Shuttle Radar Topography Mission in February 2000, NASA has released an image of the (Turkish Bogazici) Strait, which is considered to be the boundary between Europe and Asia.

  6. Changing Antarctica Viewed by NASA Satellite April 11, 2002

    NASA instruments flying on the Terra satellite have observed the calving of an iceberg and the breakup of an ice shelf in Antarctica, roughly 2,100 kilometers (1,300 miles) from one another.

  7. Terra Satellite Data Confirm Unusually Warm, Dry U.S. Winter April 8, 2002

    New maps of land surface temperature and snow cover produced by NASA's Terra satellite show this year's winter was warmer than last year's, and the snow line stayed farther north than normal.

  8. NASA Images Confirm What New Yorkers Already Know: It's Dry April 3, 2002

    Whether you look at the glass as half empty or half full, reservoirs at 52 percent of capacity for a major metropolitan area spell trouble.

  9. NASA Pinpoints Where Rain Comes from and Where It Goes April 1, 2002

    A new NASA computer model can now tell exactly where in the world rain or snow that provides local water originated.
