I absolutely object to NASA'S reckless practice of using plutonium fuel in space
The Mars Science Laboratory's rover, known as "Curiosity," will be fueled with 4.8 kilograms (10.56 pounds) of plutonium dioxide!
Accidents can and DO happen, and they always come as a surprise. Just remember those killed in the Challenger mission. Remember Fukushima, Chernobyl, or the "unforeseen" circumstances now unfolding in Los Alamos, and Nebraska.
A release of plutonium from an accident upon launch could be catastrophic to the entire planet.
Please permanently ban the use of any nuclear fuel in any space missions.
