NASA’s 2004 budget request, officially embargoed until U.S. President George W. Bush presents his spending plan to Congress in February, contains significantly increased funding for a revamped nuclear propulsion research effort the U.S. space agency is now calling Project Prometheus. A source familiar with the NASA budget request for 2004 told Space News that the amount of money the White House is requesting strongly suggests an expansion of the program. “There is significant money in the budget for Prometheus,” the source said. “More than I expected to see.”
