Shuttlepod 05 of the Enterprise-D, a copy of which is found adrift in 2365 carrying a second Captain Picard from six hours in the future, in the episode Time Squared.
The El-Baz is a Type 15 shuttlepod of the Enterprise-D, numbered 05, that features in the second-season Star Trek: The Next Generation episode Time Squared. It is named after Farouk El-Baz, the geologist who helped to train the Apollo astronauts.
In 2365 the Enterprise comes upon the pod tumbling in space without power. Brought into the shuttlebay, it proves to be an exact double of the El-Baz already on board, and inside is an unconscious, disoriented Jean-Luc Picard. The pod's log shows that it left the ship six hours in the future, just before the Enterprise was destroyed in an energy vortex.
The future Picard had hoped to draw the vortex away by leaving. The present Picard stops him from repeating the attempt and orders the ship into the centre of the vortex instead, which breaks the loop. The duplicate pod and its passenger then vanish.
