\begin{document}  \section{Introduction}  Terraforming other planets is a long-standing human goal. With the ever-increasing threat of global nuclear warfare, the need for a back-up planet has become more real. Mars is a great candidate for terraforming due to its similarity to Earth and its relatively close proximity. Humans could effectively solve two problems at once by terraforming Mars using radioactive material. Our project will investigate the amount of energy needed to terraform Mars and to see if radioactive material can realistically provide that amount of energy.
