Pasadena - Jul 22, 2003 - Recent near-infrared images from a new camera called PANIC (Persson's Auxilliary Nasmyth Infrared Camera) on the 6.5-meter Clay telescope at Las Campanas Observatory, Chile, confirm that the camera and telescope hold a promising future for understanding the nature of dark energy, exploring the formation and evolution of distant galaxies, and identifying protoplanetary material around young stars.

Houston - Jul 22, 2003 - For more than 20 years, NASA has flown high-altitude research aircraft to collect cosmic dust - debris of comets and asteroids that fills the inner solar system. In late April though, they made the first attempt to collect dust particles from a very specific target - comet Grigg-Skjellerup.

Argonne - Jul 22, 2003 - Argonne physicists have precisely measured the masses of nuclear isotopes that exist for only fractions of a second or can only be produced in such tiny amounts as to be almost nonexistent in the laboratory. Some isotopes had their masses accurately measured for the first time.

Wright-Patterson - Jul 22, 2003 - As the Mars exploration rovers "Spirit" and "Opportunity" race toward the Red Planet, part of the Air Force Research Laboratory is soaring with them. The two rovers, expected to touch down and explore opposite sides of Mars in early 2004, are powered by rechargeable lithium-ion batteries researched and developed by experts at the laboratory's propulsion directorate. Spirit and Opportunity will act as robot geologists while on the surface of Mars.

Paris (ESA) Jul 21, 2003 - Expertise derived from working on the joint NASA-ESA Cassini-Huygens mission to Saturn and its moon Titan is now being applied to underground drilling machines. This is providing tunneling engineers with an improved ability to virtually 'see' some 40 metres into solid rock and pinpoint obstacles ahead.
