摘要

In the US President Bush signed into law a 2005 $16.2 billion budget for NASA, an increase of about $822 million from 2004. This last was a package funding the entire Project Prometheus program at $430 million and provides $10 million for nuclear thermal propulsion at the Marshall Space Flight Center. In Greek mythology, Prometheus was the wisest of the Titans; he gave the gift of fire to humankind (the name Prometheus means in Greek 'forethought'). Although now given a lower priority, NASA is still developing plans for an ambitious mission to orbit three planet-sized moons of Jupiter — Callisto, Ganymede and Europa — which may harbor vast oceans beneath their icy surfaces. The mission, called the Jupiter Icy Moons Orbiter, would orbit each of these moons for extensive investigations of their makeup, their history and their potential for sustaining life. NASA's Galileo spacecraft found evidence for these subsurface oceans, a finding that ranks among the major scientific discoveries of the Space Age. Although put in indefinite hold because of Project Constellations and its Return to the Moon plans, we hope that the ideas considered in this paper will reinforce the case for nuclear propulsion, in particular nuclear thermal propulsion, and support the revival of this technology.
