Nuclear-powered Mars Curiosity set to launch in November

Nuclear-powered Mars Curiosity set to launch in November!!! this awesome news! "Curiosity’s generator is built to withstand launch explosions or the extreme heat — up to 3,000 degrees Fahrenheit — that would be encountered during an inadvertent atmospheric re-entry after an upper-stage engine failure.
The plutonium dioxide fuel is protected by several layers of safety. Fuel pellets the size of marshmallows are sheathed in a dense, iridium heat shield. The pellets are bundled in pairs in high-strength graphite shells designed to absorb the most powerful possible impacts. And those shells are wrapped with ablative sleeves made of carbon-bonded fiber." read more:
