al, http://arxiv.org/abs/1506.03105 [3] Radioisotope Thermoelectric Generator. A power source used for all deep space probes. It uses the decay of radioactive material, to generate electricity an keep the probe warm. Solar power is not a practical alternative, NASA uses Plutonium, and doesn't have enough, because Congress doesn't care. ESA is developing their own, using Americium. ### Thanks for reading my short story! I hope you enjoyed it. If you did (hooray!) would you be comfortable rating it, or posting a review at the site you got it from? It'll help others find it who may also enjoy it. Currently, I'm working on The Hundred Gram Mission. It's about an expedition to Alpha Centauri, in the context of a world suffering climate change. Can we afford Big Science when refugees cram our streets? And isn't it just as tragic if we decide we can't? An excerpt from The Hundred Gram Mission follows.
