Palo Alto - Mar 17, 2003Space Systems/Loral has resumed construction of WildBlue-1, the world's first commercially dedicated all-Ka-band, multiple spot-beam broadband satellite, for WildBlue Communications, Inc., Denver, CO. WildBlue-1 will generate more than 10 kW of power at beginning of life, and will cover North America with 41 overlapping Ka-band spot beams. Eight tracking antennas on board the satellite provide precision pointing of the beams over the contiguous United States. |

New Crystalline Structures May Open Door to Molecular Filters
Rochester - Mar 17, 2003Imagine a mask that could allow a person to breathe the oxygen in the air without the risk of inhaling a toxic gas, bacterium or even a virus. Effectively filtering different kinds of molecules has always been difficult, but a new process by researchers at the University of Rochester may have paved the way to creating a new kind of membrane with pores so fine they can separate a mixture of gases. Manpower Reductions Planned Throughout Space Command 
Peterson AFB - Mar 17, 2003Air Force Space Command will trim 1,125 employee positions over the next seven years as part of an Air Force initiative to realign more than 13,000 active-duty and civilian manpower authorizations by 2010. Teets, Lord Tell Senate The Nation Needs 'Space Cadre' 
Washington - Mar 17, 2003The Air Force's top two space officials told lawmakers March 12 that development of a "space cadre" was one of their top agenda items for national security space programs in 2004. |
Global Warming Could Trigger Cascade Of Climatic Changes
Corvallis - Mar 17, 2003Global warming and the partial melting of polar ice sheets can dramatically affect not only sea levels but also Earth's climate, in ways that may be complex, rapid and difficult to adjust to, scientists say in a new study to be published Friday in the journal Science. SIRCUS Adds Accuracy To Ocean Color Mapping 
Boulder - Mar 17, 2003As a result of recent measurement corrections made possible by the National Institute of Standards and Technology (NIST), the Earth's oceans may look a bit bluer than they did before in satellite images--meaning there may be less carbon in the oceans than previously thought. Collapse Of Antarctic Ice Sheet Triggered End Of Last Ice Age 
Toronto - Mar 17, 2003The melting of an Antarctic ice sheet roughly 14,000 years ago triggered a period of warming in Europe that marked the beginning of the end of the Earth's last ice age, says a new study. |
El Nino Collapse Lacks Harmony
Huntsville - Mar 17, 2003Sometimes Earth scientist Bill Patzert wishes he had a degree in psychology. It might help him understand El Nino. Vanguard 1 Marks 45 Years in Space 
Washington - Mar 17, 2003Vanguard I, the world's longest orbiting man-made satellite, built by the Naval Research Laboratory and launched at Cape Canaveral, Florida, in 1958, will mark its 45th year in space on March 17. In the years following Vanguard's launch, the small satellite has made more than 178,061 revolutions of the earth and traveled over 5.1 billion nautical miles. |
Preaching Settlement
Scottsdale - Mar 17, 2003There is a way to change the space agenda now, while we hold the world's attention in the wake of Columbia's loss. The lever for that change is not a new hardware program, legislative package or business plan. Rather, it is a clear, comprehensible goal explained in simple and compelling language at every opportunity. That goal is the opening of space to human habitation and settlement. |
