NASA's Plutonium Supply Dwindling; ESA To Help

astroengine writes "NASA's stockpile of the plutonium isotope Pu-238 is at a critical level, causing concern that there won't be enough fuel for future deep space missions. Pellets of Pu-238 are used inside radioisotope thermoelectric generators (or RTGs) to generate electricity for space probes traveling beyond the orbit of Mars — solar energy is too weak for solar arrays at these distances. Blocked by a contract dispute with Russia to supply Pu-238 and the US Department of Energy that has not been granted funds to produce more of the isotope, NASA lacks enough of the radioisotope to fuel the future joint NASA-ESA mission to Europa. However, the head of the European Space Agency has announced that they have plans to commence a new nuclear energy program to alleviate the situation."

      Luckily another contaminant, U-236, is also formed when the small amount of contaminant U-235 present in the initial yellowcake acquires a neutron in the breeder reactor to become U-236 with a ten million year half life (before it spontaneously fissions after humans are extinct). If it captures a second stray neutron in there before that happens eons from now, then it beta decays to Np-237 with a half life of one week, but that means we get extra electron to grab onto! A [suicidal] high school chemistry class could then isolate this neptunium from the plutonium, easily within a few days (to reach the deadline).

      After you have so easily isolated the pure neptunium (and buried the dead chemists), you just shine more neutrons on it, and voila, you get alpha emitter Pu-238 with a half life of 90 years. (Before it decays to "stable" U-234 which has its own half life of 27000 years making it someone else's problem.) Cram a thermoelectric generator full of Pu-238 and hold it at arms length from your electronic toys, and you've got a nice battery that lasts for decades for trips outside the solar system.

      For a neutron source, spontaneous fission will usually suffice, certainly for civilian or nuclear reactors. But when timing is absolutely critical, a more reliable neutron source can be made from an emitter of fast alpha particles (Pu-238, Ra-226, Po-210, whatever) irradiating beryllium-9. The alpha particle has an inelastic collision with the beryllium which produces a carbon-12 nucleus and a fast neutron- or a thermal neutron if it keeps bouncing off carbon and beryllium nuclei. Fast neutrons pack more energy if they hit and can overcome kinetic barriers to fuse with nuclei, but slow ones spend more time poking around nuclei and may even tunnel through barriers. Whether you want fast or slow depends on how you have arranged the fuel, the moderator, and any neutron absorbent or reflective materials in your device.

      Those solar panels ALSO radiate to the cold sky (at least the back does, eh?) although insulation helps.

For a freeflying spacecraft, there might be fixes that can be executed automatically (e..g maneuver the s/c automatically.) but the whole idea of "safe hold" is that something serious has gone wrong and you don't want the spacecraft doing things by itself.

    Remember, the US government cancelled the Constellation program and post-Shuttle manned spaceflight capabilities, with the hopes that they'd *buy seats* on Russian spacecraft.

    And now they can't even agree on buying some plutonium from Russians?

    How many people really think that buying those seats on Russian shuttles will happen without any problems?

    Face it, America gave away its manned spaceflight. Making deals with Russia can't be relied on -- even small things like plutonium can't be reliably obtained, let alone manned spaceflight through Russians.

    We gave it away. And now our manned spaceflight is screwed.

    For damn near 200 years the GP method was working. Not that the US got everything right (destroying the natives, slavery, etc...), but it was always at least trying to be ahead of the curve. The US was the place where tomorrow is going to be better than yesterday. It was working. People no matter how oppressed can see that if you do things better then your life will improve. The US was the shining example. Over the last 30-40 years we have done nothing but backpedal, and this has done far far more to bolster oppression in the world than any military action. Being an example is a long term goal. The progressive movement works, good does beget good, it just takes a while. No other "solution" has even come close to succeeding.

    Jupiter, Venus, Mars, Pluto.. all Greek mythology names, why? They were "it"** back in the day.

    Those are Roman mythology names, not Greek. Which just goes to show, as the Romans were even more "it" than the Greeks.

    There's an Arabic saying that goes something like "Me and my brother would fight my cousin if he does us wrong, but if a stranger comes in, my cousin and I will team up".

    Here, we call that "the enemy of my enemy is my friend", and it hasn't worked out so well for us. It's why we cozied up to Saddam Hussein (because he was fighting with Iran) and to the mujahideen (because they were fighting the Russians) back in the '70s and '80s, and look how those situations turned out.

    Empathy? According to prevailing beliefs (held by all but ignorant red-staters), the state of those countries is what the people of those countries want, and for Americans to feel that this is wrong is to be disrespectful of Islamic culture.

    In my opinion, its a little bit more subtle than that. The wider moderate Islamic society wants peace and liberty. However, it also wants a smooth transition from the current state of affairs to the world where freedom of expression is tolerated. There's an Islamic proverb, "Better 1000 days of tyranny than 1 day of anarchy." It describes the state of affairs in Islamic culture very well. Everyone wants change, but no one is willing to risk the anarchy necessary to effect it.

    Another issue in the Islamic world is the schizoid attitude towards freedom of expression. Freedom of expression is to be demanded wherever Muslims are not free to express their religion. We see this in the reaction towards French bans on headscarves and Swiss bans on minarets. On the other hand, practitioners of non-Islamic religion and culture can have their culture suppressed. I've heard otherwise moderate and sensible Muslims say, "Ah, I would love to have the free speech of the West, if only I could filter out the 'filth.'" The thing that they're missing is that you don't get the benefits of free speech by only allowing free speech in limited areas. True, a lot of religious people believe this, but the Muslim world is the last place where religion is still dominant as a political force.

    It is only with freedom and liberty does civilization thrive.

    History disagrees. Every civilization, from Ancient Sumer, right up to our own had slavery at one point or another. The fact that we get by right now without slavery in the US says very little about the necessity of freedom and liberty for civilization. In fact, I'd almost argue the opposite - slavery and oppression are the two tools that allow civilizations to go from city or nation state to empire. Recall Rome. As a republic, it conquered Italy. Under an emperor, Rome was able to conquer most of Europe, North Africa and Asia Minor.
