NASA touts recent discoveries on Mars and the moons around Jupiter, which they say indicates that there may be or have been habitable environments on these worlds that supported the development of life.
That's the official story.
What's actually behind the White House's hawking of this space mission is their desire to promote and legitimize the industry's new nuclear propulsion technology needed to support such a mission. That would be another in a long list of moneymaking boondoggles for the aerospace industry.
To develop and demonstrate these new nuclear power and propulsion technologies, President Bush's budget proposes $279 million; ($3 billion over five years) for Project Prometheus, which builds on the Nuclear Systems Initiative started last year.
Project Prometheus includes the development of the first nuclear-electric space mission, called the Jupiter Icy Moons Orbiter. This mission will conduct extensive, in-depth studies of the moons of Jupiter that may harbor subsurface oceans. Only advanced nuclear reactors could provide the hundreds of kilowatts of power the craft would need.
Included in NASA plans for the nuclear rocket to Mars; a new generation of Radioisotope Thermoelectric Generators (RTGs) for interplanetary missions; nuclear-powered robotic Mars rovers to be launched in 2003 and 2009. NASA touts future mining colonies on the Moon, Mars, and asteroids that would be powered by nuclear reactors.
The Jet Propulsion Laboratory, a division of the California Institute of Technology, manages the Mars Odyssey mission for NASA's Office of Space Science. Additional science partners are located at the Russian Aviation and Space Agency and at Los Alamos National Laboratory. Lockheed Martin Astronautics, Denver, is the prime contractor for the project to develop and build the orbiter. Mission operations are conducted jointly from Lockheed Martin and JPL.
The Prometheus Project is based on an archaic notion that began in the '50's with a space project named Orion.
Project Orion was a propulsion system that depended on exploding atomic bombs roughly two hundred feet behind the space vehicle.
Orion was developed at the old General Dynamics Corporation, under the guidance of several former Manhattan Project scientists.
In the late 1950's, Freeman Dyson, physicist, educator, and author, joined the Orion Project research team. The project's participants proposed exploding atomic bombs at regular intervals at very short distances behind a specially designed space ship in order to propel it to the Moon and other planets in the Solar System far more quickly and cheaply than with chemical-fuel rockets.
The motto for Orion was, 'Mars by 1965, Saturn by 1970'; hauntingly reminiscent of the administration's line about Project Prometheus exploring Mars and Europa's moons.
Orion ran out of money and needed the government's help. The military agreed to take up the project, but only on the condition that it adapt itself to a military purpose. The project was later abandoned because of uncertainty about the safety and efficacy of nuclear energy, and the high cost of the speculative program. Also, because the Nuclear Test Ban Treaty of 1963 outlawed it.
"Technology must be guided and driven by ethics if it is to do more than provide new toys for the rich," Dyson, 76, said, as he received the Templeton Prize for Progress in Religion 2000.
Dyson once commented that, "Project Orion is a monument to those who once believed, or still believe, in turning the power of these weapons into something else."
Since the 1960s there have been eight space nuclear power accidents by the U.S. and the former Soviet Union, several of which released deadly plutonium into the Earth's atmosphere. In April, 1964 a U.S. military satellite with 2.1 pounds of plutonium-238 on-board fell back to Earth and burned up as it hit the atmosphere spreading the toxic plutonium dust, God knows where.
In 1997 NASA launched the Cassini space probe carrying 72 pounds of plutonium. If it had crashed or exploded in our atmosphere thousands could have been contaminated. During the Cassini RTG fabrication process at Los Alamos 244 cases of worker contamination were reported to the DoE.
Mum to all of that, the White House wants you to know that the nuclear space project will prove new technologies for future NASA missions. Like space-based weaponry.
The decision by U.S. President George W. Bush to withdraw from the 1972 Anti-Ballistic Missile (ABM) Treaty allows research beneficial to orbiting space-based lasers as part of a global missile defense shield to resume; orbiting space lasers on permanent space platforms.
Despite the administration and industry talk of Europa's moons, the Prometheus Project will pave the way for the original Pentagon plan to mount nuclear reactors on space-based platforms to power their nuclear lasers. And of course, as the Space Command also asserts, ". . . the United States must also have the capability to deny America's adversaries the use of commercial space platforms, for military purposes" Enough!
This Promethus project is a cynical attempt to commit the nation to Rumsfeld's Star War's nonsense. Bush and Europa's moons: I don't believe them!
A space-based laser system would only encourage other nations to build space-nukes to counter ours. The move to expand this type of weaponry will almost certainly provoke a space-based weapon war.
Maybe we can shoot this crazy laser down before then.
