The overall design for the Eurydice was based on the Final Report of the Ryerson ADVS Team. Their ship was intended for intercepting and deflecting a NEO asteroid, relatively similar to the initial colony mission.

The descriptions of Orpheus are extrapolations from real data; at the time of writing the exact size, mass and composition of the asteroid remains unknown. The 3D image is actually the asteroid Bacchus, 3D modelled by Scott Hudson.
