NASA Running Out of Plutonium 264
PRB_Ohio takes us to Space.com for a story about NASA's plutonium shortage, and how it may affect future missions to the far reaches of the solar system. The U.S. hasn't produced plutonium since 1988, instead preferring to purchase it from Russia. We discussed the U.S. government's plans to resume production in 2005, but those plans ended up being shelved. If NASA is unable to find an additional source, it could limit missions that take spacecraft too far from the Sun. Quoting:
"Alan Stern, NASA associate administrator for science, ... said he believed the United States had sufficient plutonium-238 on hand or on order to fuel next year's Mars Science Lab, an outer planets flagship mission targeted for 2017 and a Discovery-class mission slated to fly a couple years earlier to test a more efficient radioisotope power system NASA and the Energy Department have in development. To help ensure there is enough plutonium-238 for those missions, NASA notified scientists in January that its next New Frontiers solicitation, due out in June, will seek only missions that do not require a nuclear power source."

Second, many people should rejoice, this is a golden opportunity to decommission a warhead or two for the plutonium in it.

Oh, oh! I have an idea! Plutonium would solve everything!
Wait... ah, crap.

So at some point, circa 1988, somebody in either Reagan or Bush's administration decided it'd be easier to get Plutonium from the Soviet Union?
I'd say this is unlikely. The summary says we haven't PRODUCED plutonium since 1988, it says nothing about when we decided to purchase from Russia.
It could very well be the case that we had sufficient stockpiles in 1988 to last us several years until after the collapase of the Soviet Union.

They use noble gases as reaction mass, but a power source is required. Solar is only good near the sun, obviously, so that only leaves nuclear as a viable option.

Let me make this clear for you because you're obviously a fucking moron.
TAKING RADIOACTIVE ISOTOPES OF ANY KIND AWAY FROM PEOPLE WHO ARE LAX WITH SECURITY, AND GIVING IT TO PEOPLE WHO ARE NOT LAX WITH SECURITY MAKES SENSE.
There's your reason, it makes sense, you're wrong.
There's nothing more pathetic than douchebags like you who, once proven wrong like you were, can't just take it and move on. You have to formulate some response that attempts to make you look less wrong, because it absolutely crushes you that you were shown to be ignorant in public.
