A small ship owned by the OPA and used by Julie Mao in her work with the Belt independence movement. The Scopuli is found drifting and apparently abandoned by the Canterbury, whose crew boards her in response to a distress signal - a trap set by Protogen to lure a ship close enough to destroy and blame on either Mars or the Belt. Julie Mao had been aboard the Scopuli when she was exposed to the protomolecule and taken to Eros, where she eventually died. Her consciousness, preserved within the protomolecule, later redirects Eros away from Earth.
