MAP spacecraft in Florida for launch preparations
NASA's Microwave Anisotropy Probe is undergoing final readiness preparations at Kennedy Space Center for its upcoming launch this summer aboard a Boeing Delta 2 rocket. The craft is designed to make a full sky picture of cosmic microwave background radiation, the afterglow of the Big Bang.
Stellar disk 25,000 light years away 'resolved'
Like our Sun, stars are large gaseous spheres. However, while we are able to perceive the Sun's disk, all other stars are so far away that they normally appear as points of light. Only specialized observing techniques are able to "resolve" the images of nearby stars and to show them as extended balls of fire.

Genetically modified Earth plants will glow from Mars
In what reads like a story from a 1950s science fiction magazine, a team of University of Florida scientists has genetically modified a tiny plant to send reports back from Mars in a most unworldly way: by emitting an eerie, fluorescent glow.
Soyuz to depart station tonight with Tito
Dennis Tito's space joyride is drawing to a close. The first fare-paying tourist of the final frontier and two Russian cosmonauts are slated to depart the international space station Saturday night for their journey back to Earth aboard a Soyuz capsule.

Odds of planet formation in Orion Nebula reduced
In 1993, when the Hubble Space Telescope surveyed the Orion nebula for the first time, its images provided a substantial boost for the argument that stars with planetary systems are commonplace in the galaxy. Now, however, the most recent analyses of one the youngest, closest and brightest nebulae suggest that planets may be far rarer than thought.
Future aircraft might morph its features in flight
A future aircraft might morph its wings, use smart sensors and actuators and more accurately mimic nature's methods of flight. NASA Administrator Dan Goldin described the aircraft as one of the linchpins of the Agency's aerospace research for the next 20 years.
Colliding galaxies provide clues to star formation
By comparing computer simulations of a galaxy collision with actual observations, astronomers at the University of Illinois have found discrete star-formation episodes that may help explain the prodigious star-formation rates that occurred in the early universe.
