From Voyager spacecraft to atom smashers, America's long-term research faces an era of budget cuts.
For decades, American scientists have unlocked nature's secrets, generated an enormous number of patents, and earned a string of Nobel Prizes.
These days, however, pride of accomplishment is mingling with angst as Washington contemplates research cuts on everything from space weather to high-energy physics. The concern? The United States unwittingly may be positioning itself for a long, steady decline in basic research - a key engine for economic growth - at a time when competitors from Europe and Asia are hot on America's heels.
Observers point to several examples in the White House budget proposals for fiscal 2006, which begins in October:
• To align itself with President Bush's vision for space exploration, the National Aeronautics and Space Administration has notified mission managers of its intent to pull the plug on several projects, including the prized Voyager spacecraft. These 28-year-old craft are now approaching the solar system's edge - with enough power left to keep them phoning home until 2020 about regions of space that humans are unlikely to probe again for decades.
Other potential casualties include satellites critical to understanding and forecasting solar storms - which can damage satellites, cause blackouts on Earth, and threaten humans living and working in space - as well as several Earth-observing satellites needed for climate research and other environmental-monitoring activities.
• At the Department of Energy, the Office of Science faces a second year of cuts, affecting programs ranging from energy research to high-energy physics. By some accounts, the US may be out of the experimental side of high-energy physics altogether in five years unless its bid to host a planned international linear collider is successful.
