Beach rover uncovers Mars's ancient oceans

The landing site of the Mars rover Opportunity was once the shore of a shallow, salty sea, NASA scientists have declared. The weight of evidence now gathered makes the conclusion unequivocal, they say. - New Scientist, March 24, 2004.

Wire-growth process leads to flexible nanosystems
An approach to creating single-crystal nanowires from just about any semiconducting material is being pioneered by Charles Lieber and his group at Harvard University in tandem with the nanotech startup he co-founded, Nanosys Inc. Together with methods for placing wires in arrays and multilayers, the technique promises to create complex systems at nanoscale. - EETimes March 24, 2004


5000-mph X-43A Vehicle Ready for Flight
NASA has set Saturday, March 27 for the flight of the experimental X-43A research vehicle. The flight is part of the Hyper-X program, a research effort to demonstrate alternate propulsion technologies for access to space and high-speed flight within the atmosphere. The flight will provide unique free flight data about hypersonic (faster than Mach 5) air-breathing engine technologies. The unpiloted 12-foot-long vehicle, part aircraft and part spacecraft, will be dropped from a B-52. It will be boosted to nearly 100,000 feet by a rocket and released over the Naval Air Warfare Center Weapons Division Sea Range over the Pacific Ocean off the coast of southern Calif. It is expected to fly under its own power at about 5,000 mph. -MoontoMars.com, March 24, 2004
