  • Compact Disc Puts Lab in a Spin
    Testing in the field for signs of life has not always been convenient, cheap or unambiguous. Combining many off-the-shelf biology tests, a compact disk under NASA evaluation for future missions may simplify the remote functions of a modern laboratory.

  • Metal in the Meadow
    Dave DeBoer, Project Engineer for Allen Telescope Array, discusses what the unique telescope will offer. The Allen Telescope Array is marked by many innovations crafted with express purpose of building a world-class state-of-the-art astronomical facility at a price of existing radio telescopes.

  • Ion Drive to the Moon
    A new mission to survey the moon, called SMART-1, will also demonstrate a number of technologies for efficient space travel, including solar and ion propulsion. The probe launched flawlessly on September 27, and is currently on course for its lunar rendezvous.

  • Bridging the Gap: Part III
    Renowned physicist, Freeman Dyson, has proposed some of the most compelling concepts for space explorations. These range from a theory of life's origins--the "double-origin hypothesis"--which posits two separate creatures at the beginning, one replicating and the other metabolizing.

  • Bridging the Gap: Part II
    Renowned physicist, Freeman Dyson, has proposed some of the most compelling concepts for space explorations. These range from a theory of life's origins--the "double-origin hypothesis", which posits two separate creatures at the beginning, one replicating and the other metabolizing--to the "Dyson Sphere".

  • SMART-1: Chips Off the Terrestrial Block
    The first European lunar probe, called SMART-1, is scheduled to launch toward the moon in the next few weeks. Its primary goal will test theories of how the moon formed and evolved, along with any potential polar water-ice history.

  • Infrared Eyes Set For the Sky
    A new Sun-circling telescope will reveal the universe with infrared eyes. Unlike what the Hubble Space Telescope shows in visible light, this Space Infrared Telescope Facility (SIRTF) will look for heat. The longer, infrared wavelengths can penetrate dust and gas clouds that otherwise obscure.

  • Dinner with da Vinci
    Leonardo da Vinci dreamed of manned flight. While his genius is secured by paintings and inventions, Leonardo's keen observations of nature led him into astronomy. As with most of his work, his insights were highly original and prescient.

  • Hubbub on Hubble
    The Hubble Space Telescope mission is currently planned to continue to year 2010. Final checkout will occur in fourth servicing mission, which is expected to be launched on May 5, 2005. Given this launch baseline, the formal probability of continuous science operations through 2010 is

  • Earth Without Life?
    The Mars Express spacecraft snapped a new panorama of the Earth and Moon in silhouette against a dark sky. The views back at our own planet reveal a blue dot, rich with oceans and clouds, but how does our planet's chemistry hold up for comparison

  • The Cogs of Precognition
    A recent European Space Agency report details the most promising investments for future technology, based on a studied wish-list borrowed from diverse arts. Their unique methodology prepared more than two hundred technical dossiers about what might be 'the next big thing' along with hints on

  • Homes Away From Home: Map III
    NASA's Solar Exploration roadmap details both what is known about our neighborhood, and what new discoveries are hoped for in future missions. This three-part series examines the storyline behind how life came to Earth, and how we might seek to find it elsewhere.
