INTERNATIONAL SPACE STATION STATUS REPORT

The oxygen-producing Elektron unit aboard the Space Station continues to function well, as it has since it was restarted early last Saturday. Expedition 8 Commander Michael Foale and Flight Engineer Alexander Kaleri spent two days last week replacing a liquids unit and a water flow system of the Russian Elektron, in the Zvezda Service Module. The Elektron separates water into oxygen and hydrogen. The oxygen is used in the Station’s atmosphere, while the hydrogen is vented over board.

URBAN LAND USE VIA SATELLITE

According to NASA-funded researchers, developed land in the greater Washington-Baltimore metropolitan area is projected to increase 80 percent by 2030. Scientists used a computer-based decision support model loaded with NASA and commercial satellite images to simulate three policies affecting land use.

The researchers, Claire Jantz and Scott Goetz, from the University of Maryland, College Park, Md., and the Woods Hole Research Center, Woods Hole, Mass., also found a 39 percent increase in developed land in the region from 1986 to 2000. Some of the most striking changes occurred around the Dulles Airport area in Northern Virginia.

LAND COVER CHANGES AFFECT CLIMATE ?

While climate may be impacted by carbon dioxide emissions, aerosols and other factors, a new study offers further evidence land surface changes may also play a significant role.

The study of summer climate in the United States reported changes in land cover, particularly vegetation, have impacted regional temperatures and precipitation. The study used data and computer models from NASA and other organizations such as the National Oceanic and Atmospheric Administration (NOAA).

Orbiting Hurricane Hunter back in action

After a three-year gap, the European Centre for Medium-Range Weather Forecasts is again routinely assimilating data from an instrument aboard ERS-2 that ‘sees’ wind fields over the ocean. The result is more accurate weather predictions ­ particularly in forecasting strong storms and hurricanes.

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 that have large potential pay-offs. The unpiloted 12-foot-long vehicle, part aircraft and part spacecraft, will be dropped from a B-52,aircraft. 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 will fly under its own power at approximately 5,000 mph.
