The USS Adventure was the first ship of the Adventure starship class, and the last. Due to a computer malfunction, all but one member of the crew was killed on it's mission to Jupiter. The single survivor was able to return the ship to Earth after deactivating the computer. Due to computer problems, as well as issues with the control systems for the stasis pods and reactor core, the Adventure was the only ship of it's class ever launched. The malfunction is believed to have been caused by radiation from a solar flare, when the magnetic shields were unable to protect the computer core.
