  • Setting Sail for the Stars

    June 28, 2000

    Scientists met last month to discuss the latest developments in solar sail technology. A new mission, the Interstellar Probe, could carry a spacecraft beyond the edge of the solar system by 2018.

  • Learning from Lightning

    Dec. 17, 2000

    Little by little, Lightningsensors in space are revealing the inner workings of severe storms. Scientists hope to use the technique to improve forecasts of deadly weather.

  • Sedimentary Mars

    Dec. 4, 2000

    New Mars Global Surveyor images reveal sedimentary rock layers on The Red Planetthat may have formed underwater in the distant martian past.

  • Black Holeson the Loose

    Jan. 14, 2000

    Astronomers have discovered isolated Black Holesadrift among the stars in our galaxy.

  • Water on the Space Station

    Nov. 2, 2000

    Rationing and recycling will be an essential part of life on the newly-populated International Space Station. In this article, the first of a series about the challenges of living in orbit, Science@NASA explores where the crew will get their water and how they will (re)use it.

  • Eros or Bust

    Feb. 8, 2000

    As any dinosaur can tell you, it's important to keep an eye on Near-Earth Asteroids. On February 14, 2000, NASA's NEAR spacecraft will go into orbit around 433 Eros for a year-long closeup look at a 21 mile long space rock. Data collected during the mission could revolutionize our understanding of the solar system's "minor planets."

  • The RADAR Cop in Space

    March 24, 2000

    NASA's IMAGE satellite, scheduled for launch on March 25, will revolutionize our understanding of Earth's magnetosphere. Space Weatherdata from the innovative spacecraft will be freely available to the public on the web and elsewhere. NASA scientists are developing plans for down-to-earth listening stations that HAM radio operators can build to capture the data themselves.

  • S-bursts

    May 23, 2000

  • Antibiotics in Orbit

    Aug. 25, 2000

    Pilot studies indicate that microbial antibiotic production can be increased by up to 200 percent in space-grown cultures. Scientists who studied such antibiotics during the "John Glenn" shuttle mission in 1998 are looking forward to more low-gravity experiments on the International Space Station.

  • Here Comes Urban Heat

    March 16, 2000

    With summer just around the corner, NASA scientists are using space age technology to understand how characteristics of the urban environment create "urban heat islands.
