  • Mars meets anti-Mars

    Sept. 13, 1999

    The Red PlanetMars and the brilliant red star Antares pass less than three degrees apart this week. The pair are easy to find in the night sky just after sunset. Stargazers with dark skies can catch a glimpse of the Galactic Center region at the same time.

  • Learning how to make better "nowcasts" of weather

    July 2, 1999

    Weather researchers and forecasters meet to discuss closer ties to improve "nowcasts" - or forecasts of what the weather will do in the next few hours.

  • Rocket will study Space Weathereffects

    Jan. 7, 1999

    Scientists plan a CAPER to study the solar wind high above the arctic circle, in Norway. They hope to find out how atoms from Earth's upper atmosphere have escaped to become part of Earth's "auroral fountain."

  • Setting Sail for the Stars

    April 8, 1999

    Cracking the whip and unfurling gray sails are among new Space Transportationtechniques under discussion at the 1999 Advanced Propulsion Research Workshop.

  • Polar Lander Mission Overview

    Nov. 30, 1999

    The latest Mars lander will look for water and study martian climate.

  • Sightings

    May 6, 1999

    New software from NASA, called "J-Pass," can tell you when and where to spot satellites passing overhead - from your own backyard.

  • Solar Cycle Update

    Oct. 14, 1999

    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.

  • A New Class of Black Holes?

    April 13, 1999

    Astronomers may have discovered a new type of middle-weight black hole in the centers of some nearby galaxies.

  • Venus Lends a Hand

    June 24, 1999

    En route to Saturn, Cassini flew less than 400 miles above Venus today, gaining a boost in speed from that planet's gravity.

  • Up, Up, and away to the Magnetosphere

    Jan. 21, 1999

    A Space Weatherrocket blasted off from a launch pad in Norway, early this morning. During its successful 20 minute flight, its instruments gathered valuable data on the auroral fountain, where solar wind directly interacts with Earth's atmosphere.
