STS-104: ISS airlock
Space shuttle Atlantis' STS-104 mission in July 2001 delivered the $164 million Joint Airlock to the International Space Station. The module, named Quest, gave the outpost a new doorway for American and Russian spacewalks. The five Atlantis astronauts narrate the highlights of their mission in this post-flight film.

Dark matter hides, physicists seek
Scientists don't know what dark matter is, but they know it's all over the universe. Everything humans observe in the heavens‹galaxies, stars, planets and the rest‹makes up only 4 percent of the universe, scientists say. The remaining 96 percent is composed of dark matter and its even more mysterious sibling, dark energy.

Scientists work to improve space weather predictions
New instrumentation and observing techniques, being developed by researchers at the University of Illinois at Urbana-Champaign, are helping scientists better understand and predict space weather. Space weather can be caused by giant solar flares and coronal mass ejections from the sun, and can adversely affect life on Earth.

Shuttle boss talks landing day vs. inspection debate
The decision earlier this week to add a spacewalk to Discovery's mission and still preserve a final heat shield inspection today forced managers to delay re-entry one day to Friday and in so doing, give up a landing opportunity. NASA flight rules require a landing attempt Friday, even if that means diverting the shuttle to California or New Mexico. The latter option is a worst-case scenario that could expose the orbiter to sub-freezing weather and delay the ship's return to Florida by four to six weeks.

Telescope picks up glow of universe's first objects
New observations from NASA's Spitzer Space Telescope strongly suggest that infrared light detected in a prior study originated from clumps of the very first objects of the universe. The recent data indicate this patchy light is splattered across the entire sky and comes from clusters of bright, monstrous objects more than 13 billion light-years away.

Stardust findings override commonly held beliefs
Contrary to a popular scientific notion, there was enough mixing in the early solar system to transport material from the sun's sizzling neighborhood and deposit it in icy deep-space comets. It might have been like a gentle eddy in a stream or more like an artillery blast, but evidence from the Stardust mission shows that material from the sun's vicinity traveled to the edge of the solar system, beyond Pluto, as the planets were born.
