No Nukes in Space


Since the late 1980's journalism professor Karl Grossman has been writing about nuclear power in space.  He was one of the founding members of the Global Network Against Weapons & Nuclear Power in Space when it was created in 1992.  Today he remains on the organization's Advisory Board.

Karl's latest article, released today, comes just a day after another rocket launch failure at Cape Canaveral in Florida.

Featured on CounterPunch Karl's article is entitled A Planetary Risk: The Perils of Nuclear-Powered Space Flights.  Below are a few excerpts from the piece and the full article can be read here.

You can also sign our petition calling on NASA & Congress to stop plans for nuclear power in space here.

NASA has released a study claiming there is a need for continued use of plutonium-energized power systems for future space flights. It also says the use of actual nuclear reactors in space “has promise” but “currently” there is no need for them.

The space plutonium systems—called radioisotope thermoelectric generators (RTGS)—use the heat from the decay of plutonium to generate electricity in contrast to nuclear reactors, usually using uranium, in which fission or atom-splitting takes place.

Examples of the use of benign power in space include the successful flight in May of a solar-powered spacecraft named LightSail in a mission funded by members of the Planetary Society. Astronomer Carl Sagan, a founder of the society, was among those who have postulating having a spacecraft with a sail propelled through the vacuum of space by the pressure of photons emitted by the sun. LightSail demonstrates his vision.

NASA Administrator Charles Bolden, a former astronaut and Marine Corps major general, remains a big booster of using nuclear-propelled rockets to get to Mars. Work on such a rocket has been going on at NASA’s Marshall Space Flight Center. NASA on its website says that a nuclear-powered rocket “could propel human explorers to Mars more efficiently than conventional spacecraft.”

Through the years, NASA has worked closely with the U.S. Atomic Energy Commission and after the commission was disbanded its successor, the Department of Energy, on space nuclear programs. And there’s a program at DOE’s Los Alamos National Laboratory to develop a “robust fission reactor prototype that could be used as a power system for space travel,” according to Technews World.
This is occurring despite Russia now abandoning its development of nuclear-propelled rockets for missions to Mars, a project it had earlier much-heralded. Reported TASS in April:

“Russia’s space agency Roscosmos is planning to shut down works on developing a megawatt-class nuclear propulsion system for long-range manned spacecraft.”
“We’ve known for years that the nuclear industry has taken control of the seats at the NASA and DOE planning committees that decide whether solar or nuclear power should be used on space missions,” said Bruce Gagnon, coordinator of the Global Network Against Weapons & Nuclear Power in Space. “The nuclear industry views space as a new market for their deadly product. Nuclear generators on space missions, nuclear powered mining colonies on Mars and other planetary bodies and even nuclear reactors on rockets to Mars are being sought. Thus there are many opportunities for things to go wrong.”
“Over the years, inside the DOE labs, hundreds of workers have been contaminated while fabricating space nuclear devices. It is not just some theoretical chance of a space launch accident that we are concerned about. We oppose the entire space nuclear power production process,” he said. “It’s all dangerous!”

“Just like here on Earth there is a tug-of-war going on between those who wish to promote life-giving solar power and those who want nukes,” said Gagnon. “That same battle for nuclear domination is being taken into the heavens by an industry that wants more profit—no matter the consequences. The Global Network will continue to organize around the space nuclear power issue by building a global constituency opposed to the risky and unnecessary nukes in space program.” The Global Network is based in Maine.
