Cosmic ray nuclei arrive on Earth with energies of up to 3x10^20 eV (~50Joules), a macroscopic energy focused on a single sub-atomic particle. Despite nearly 100 years since their first observations, little is still known about the sources of these particles and the processes by which they acquire such tremendous energies. At rates of < 1 / km^2 / century, detecting these particles and extracting information from them requires detector arrays the size of small nations. In this talk, I will give a brief review of current experimental results followed by the presentation of a concept for a radio detector in low lunar orbit designed to reveal and characterize the sources of the highest energy particles observed.
