  • Voyage to the Giant Asteroids--Liftoff!

    2007April 6, 2011

    NASA's Dawn spacecraft has left Earth on a mission to explore the giant AsteroidsCeres and Vesta. Today's Science@NASA story explains the scientific reasons for making the trip.

  • Tether Origami

    2007April 6, 2011

    A Japanese tether of novel construction could unfold new opportunities in space.

  • The Adventures of ASTRO and NextSat

    2007April 6, 2011

    A pair of Robotsnamed ASTRO and NextSat have been working together in Earth orbit, docking, undocking, flying around and refueling, as if they have minds of their own.

  • Bargain Basement Satellites

    2007April 6, 2011

    NASA scientists have developed a fast and easy-to-build satellite named FASTSAT that could accelerate the pace of space exploration.

  • Space Medicine

    Researchers discuss how to keep Astronautssafe and healthy during long trips through the solar system.

  • Patches for a Broken Heart

    2002April 6, 2011

    Researchers using a space-age device called a bioreactor have grown patches of heart tissue that beat and respond much like a real human heart.

  • Houston, are we there yet?

    2002April 6, 2011

    This month Science@NASA is publishing a series of stories about the technology of space exploration. Today's installment, the second, is about the engines that will propel our future spacecraft.

  • Super Spaceships

    2002April 6, 2011

    Imagine a "holistic spaceship" that behaves eerily alive--even telling you when it feels bad; that travels much faster and weighs much less than ordinary spacecraft; that scientists will design molecule-by-molecule. NASA researchers say it's not so far-fetched!

  • Silicon Sidekicks

    2002April 6, 2011

    NASA's successful Sojouner Mars rover had the computing power of a cricket, more or less. Researchers say we'll have to do better than that if we're serious about exploring the solar system. This story describes the emerging new technologies of smart Robotsthat will precede and later accompany human space travelers.

  • Hitchhiker's Guide to an Asteroid

    2002April 6, 2011

    Learning what near-Earth Asteroidsare made of and how they're put together is simply prudent. NASA's NEAR spacecraft got a closer look at one when it landed on 433 Eros in 2001.
