Wired News: Race to the Moon for Nuclear Fuel
NASA's planned moon base announced last week could pave the way for deeper space exploration to Mars, but one of the biggest beneficiaries may be the terrestrial energy industry.
Nestled among the agency's 200-point mission goals is a proposal to mine the moon for fuel used in fusion reactors -- futuristic power plants that have been demonstrated in proof-of-concept but are likely decades away from commercial deployment.
Helium-3 is considered a safe, environmentally friendly fuel candidate for these generators, and while it is scarce on Earth it is plentiful on the moon.
As a result, scientists have begun to consider the practicality of mining lunar Helium-3 as a replacement for fossil fuels.
"After four-and-half-billion years, there should be large amounts of helium-3 on the moon," said Gerald Kulcinski, a professor who leads the Fusion Technology Institute at the University of Wisconsin at Madison.
Last year NASA administrator Mike Griffin named Kulcinski to lead a number of committees reporting to NASA's influential NASA Advisory Council, its preeminent civilian leadership arm.
The Council is chaired by Apollo 17 astronaut Harrison Hagan "Jack" Schmitt, a leading proponent of mining the moon for helium 3.
Schmitt, who holds the distance record for driving a NASA rover on the moon (22 miles through the Taurus-Littrow valley), is also a former U.S. senator (R-New Mexico).
The Council was restructured last year with a new mission: implementing President Bush's "Vision for Space Exploration," which targets Mars as its ultimate destination. Other prominent members of the Council include ex-astronaut Neil Armstrong.
Schmitt and Kulcinski are longtime friends and academic partners, and are known as helium-3 fusion's biggest promoters.
At the Fusion Technology Institute, Kulcinski's team has produced small-scale helium-3 fusion reactions in the basketball-sized fusion device. The reactor produced one milliwatt of power on a continuous basis.
While still theoretical, nuclear fusion is touted as a safer, more sustainable way to generate nuclear energy: Fusion plants produce much less radioactive waste, especially if powered by helium-3. But experts say commercial-sized fusion reactors are at least 50 years away.
The isotope is extremely rare on Earth but abundant on the moon. Some experts estimate there a millions of tons in lunar soil -- and that a single Space-Shuttle load would power the entire United States for a year.
NASA plans to have a permanent moon base by 2024, but America is not the only nation with plans for a moon base. China, India, the European Space Agency, and at least one Russian corporation, Energia, have visions of building manned lunar bases post-2020.
Mining the moon for helium-3 has been discussed widely in space circles and international space conferences. Both China and Russia have stated their nations' interest in helium-3.
"We will provide the most reliable report on helium-3 to mankind," Ouyang Ziyuan, the chief scientist of China's lunar program, told a Chinese newspaper. "Whoever first conquers the moon will benefit first."
