\section{Radioactive Material}   We can now determine if nuclear weapons can provide the minimum amount of energy required to terraform the atmosphere. The heat of vaporization of water at 200 K is 34.962 kJ/mol. The total amount of energy required to vaporize enough polar ice is 7.535 x 10$^{24}$ Joules. This is an incredible amount of energy, equivalent to 35880952.381 Tsar Bombas, the largest nuclear weapon ever detonated by humans.   Does Earth even have enough radioactive materials to terraform Mars? We have chosen to focus on Uranium and Plutonium as our radioactive sources because they are currently used in nuclear weapons. Also, all isotopes of these two elements are radioactive, allowing a more continual heating of Mars.  One Uranium-235 atom can release 3.24 x 10$^{-11}$ Joules of energy by fission, and one Plutonium-239 atom can release 3.318 x 10$^{-11}$ Joules. There is currently an estimated 5.9025 x 10$^9$ kg of extractable uranium on Earth
