U.S. SHIRKS LIABILITY ISSUE ON CASSINI
The "double standard" that the U.S. has created to deal with its liability in
the event of a space nuclear accident – including the current
plutonium-fueled Cassini space probe mission – is being described as an
"outright violation of the Outer Space Treaty" by the Global Network Against
Weapons & Nuclear Power in Space.
The 1967 Outer Space Treaty, the fundamental international law on space,
states that "each state party to the treaty that launches or procures the
launching of an object into outer space…is internationally liable for damage
to another state party."
Nevertheless, the U.S. in 1991 initiated a "Space Nuclear Power Agreement"
between NASA and the U.S. Department of Energy which restricts U.S. liability
in the event of a mishap on a mission involving a nuclear power system to the
limits of the U.S. Price-Anderson Act. The act limits U.S. liability in the
event of a nuclear accident to $100 million for all other nations and $8.9
billion for the U.S. itself.
"This is an outrageous double standard," declared Bruce Gagnon, coordinator
of the Global Network. "The U.S. is not, as the Outer Space Treaty requires,
agreeing to be ‘internationally liable for damage.’ It is the height of
international arrogance."
Meanwhile, this coming August 18, NASA intends to have Cassini, with 72.3
pounds of deadly plutonium, perform a dangerous fly-by of Earth. Cassini
will buzz Earth at 42,300 mph at just 729 high in what NASA calls a
"slingshot" maneuver so it can gain speed for its trip to Saturn.
If a malfunction occurs NASA admits in its Environmental Impact Statement
(EIS) that Cassini, with no heat shield, could reenter the Earth’s 75-mile
atmosphere disintegrating and releasing the plutonium globally.
In a "Safety Evaluation Report" prepared for NASA just prior to the October
1997 launch of Cassini the "Interagency Nuclear Safety Review Panel"
concluded that, "the aeroshells have not been designed for the high speed
reentry characteristic of this fly-by maneuver. Much of the plutonium is
vaporized and over a 50-year period provides a collective dose to the world’s
population…it is possible, using the linear non-threshold dose hypothesis, to
postulate up to several tens of thousands of latent cancer fatalities
worldwide over the next to years."
Independent scientists say the death toll could be much higher. Dr. Ernest
Sternglass, professor emeritus of radiological physics at the University of
Pittsburgh School of Medicine, says 20 million to 40 million people could die.
As for clean-up costs, NASA in its EIS says costs could be as high as $200
million per square kilometer and also says that a "reentry footprint" of
dispersed plutonium "could range to about 50,000 square kilometers" –
bringing the cost to $10 trillion.
NASA claims that the "likelihood" of a Cassini Earth fly-by accident is
"one-in-a-million", but Dr. Stephen Edberg of NASA’s Jet Propulsion
Laboratory admits in the award-winning investigative TV documentary "Nukes in
Space 2: Unacceptable Risks" that this estimate was "pulled out of a hat" by
NASA scientists.
Meanwhile, noted Gagnon, even if the Cassini fly-by is not diverted from
Earth NASA is planning at least eight more nuclear-fueled space shots in
coming years.
"With an accident rate of 12% in its space nuclear program already,
additional accidents are inevitable and the U.S. is thumbing its nose at the
rest of the world when it comes to covering the liability question," said
Gagnon.
Gagnon stated that the Global Network, with affiliates throughout the world,
is seeking to have nations challenge the U.S.’s "Space Nuclear Power
Agreement" in the United Nations and through the International Court of
Justice at The Hague as a violation of international law.
