Sept. 15, 2008 -- NASA is tip-toeing once again into what was once called the N-word -- nuclear -- with a technology development program aimed at powering its planned base on the moon. The goal of the Fission Surface Power Project, which is based at NASA's Glenn Research Center in Cleveland, Ohio, is to produce a non-nuclear prototype unit within five years. NASA's last foray into nuclear technologies was a project that began in 2003 known as Prometheus, which focused on both nuclear propulsion and nuclear-powered generators that ultimately could be used to support a manned mission to Mars and for deep-space probes, such as a mission to Jupiter's ocean-bearing moon Europa. Prometheus was preceded in the 1950s and 60s by the NERVA, Project Orion and other initiatives. Prometheus ended, but a small-scale effort to develop a compact, highly autonomous fission reactor as part of the agency's new exploration initiative, Project Constellation, survived. The program aims to return U.S. astronauts to the moon by 2020 and establish a base before moving on to manned missions to Mars and other bodies in the solar system. Supported at a cost of about $10 million a year, the Fission Surface Power Project this week awarded two contracts for power conversion units, used to turn the heat of nuclear reactions into electricity. NASA envisions needing a system capable of providing about 40 kilowatts of electricity -- about what's used to power eight average homes in the United States. It would be launched cold and without radioactive elements until operations were to begin on the lunar surface. |
