We investigate the possibility that cosmic rays of energy larger than the Greisen-Zatsepin-Kuzmin cutoff are not nucleons, but a new stable, massive, hadron that appears in many extensions of the standard model. We focus primarily on the S{sup 0}, a uds-gluino bound state. The range of the S{sup 0} through the cosmic background radiation is significantly longer than the range of nucleons, and therefore S{sup 0}{close_quote}s can originate from sources at cosmological distances. {copyright} {ital 1998} {ital The American Physical Society}
