After the discovery of alien technology on Mars, Scientists began experimenting with new anti-gravitic superstructures, that ultimately led to a new semi-spherical design that allowed it to move through space-time. Otherwise known as a Rift Gate, the Alpha Transporter's light yet strong superstructure, and its ability to partially move through space-time has made it an excellent large-scale transport within the Solar System. Military prototypes are currently undergoing development.
