  • Hitching a Ride on a Magnetic Bubble

    2000April 6, 2011

    NASA-funded scientists are experimenting with miniature magnetospheres as an innovative means of space transportation. If the group succeeds, next-generation spacecraft may come equipped with fuel-efficient magnetic bubbles that speed their occupants from planet to planet and ward off the worst solar flares.

  • Meltdown!

    2000April 6, 2011

    Comet LINEAR continued to blow itself apart this weekend as astronomers around the world monitored the action. The comet is still bright enough to see through amateur telescopes, but it's fading fast. This story compares the breakup of comet LINEAR with another famous fragmented comet, Shoemaker-Levy 9, that collided with Jupitersix years ago.

  • A Close Encounter with a Space Rock

    2000April 6, 2011

    This morning a half-kilometer wide asteroid is zooming past Earth barely 12 times farther from our planet than the Moon. In cosmic terms, it's a near miss, but there is absolutely no danger of a collision. Instead, the encounter offers astronomers an unusually good opportunity to study a near-Earth asteroid.

  • A Close Encounter with Asteroid Eros

    2000April 6, 2011

    NASA's NEAR Shoemaker spacecraft swooped 5 kilometers above the surface of 433 Eros on Oct 26th, marking its closest-ever approach to the tumbling space rock. Scientists hope the flyby will uncover clues about extra boulders and missing craters on the near-Earth asteroid.

  • Guess Who's Coming to Breakfast?

    2000April 6, 2011

    The NEAR spacecraft is now less than 1000 km from asteroid 433 Eros. It is scheduled to enter orbit around the space rock at 10:33 EST on Monday morning. Critical science observations are slated to begin 11 hours earlier when the spacecraft passes directly between the Sun and Eros.

  • Square Craters

    2000April 6, 2011

    NASA's NEAR Shoemaker spacecraft has spotted square-shaped craters on asteroid Eros, a telltale sign of mysterious goings-on in the asteroid belt long ago. Square craters add to accumulating evidence that the Eros is riddled with cracks and ridges that extend the entire 33 km length of the peanut-shaped space rock.

  • Advanced Space Propulsion Workshop

    2000April 6, 2011

    Scientists and engineers are gathering in Pasadena today to discuss cutting-edge research in Space Transportationat a workshop sponsored by the NASA Marshall Space Flight Center and the Jet Propulsion Laboratory.

  • Perseid Dawn

    2000April 6, 2011

    The Perseid meteor shower peaks on August 12, 2000. This year the bright, nearly-full Moon will outshine the Perseids most of the night, but for an hour between moonset and sunrise on Saturday morning, star gazers could witness a brief but beautiful meteor shower.

  • The Extraordinary Geomagnetic Perseid Meteor Shower

    2000April 6, 2011

    An interplanetary shock wave from the Sun struck Earth's magnetosphere just before the peak of the Perseid meteor shower on August 12, 2000, triggering a powerful geomagnetic storm. Stargazers across Canada and the United States were treated to the rare spectacle of a meteor shower seen against the backdrop of colorful Northern Lights.

  • Evil-doers Beware! Space Scientists are on the Case

    2000April 6, 2011

    Two NASA scientists are working with the police and the FBI to track down criminals using out-of-this-world video technology. The new technique, called VISAR, is also expected to improve military reconnaissance, medical research and video on home computers.
