Alpha Onias expedition

In 2367, Barash created a holoprogram of a fictional future based on William T. Riker's thoughts and expectations. In Riker's fictional service record in the holoprogram, the Alpha Onias expedition was an expedition to the planet Alpha Onias III by the USS Enterprise-D. The Enterprise was investigating a signal emanating from the planet's surface that had probed the Federation starship. An away team, led by Riker, and consisting of Geordi La Forge and Worf was given the task of tracking down the signal. During the course of the expedition, Riker was infected by Altarian encephalitis. This virus did not affect La Forge or Worf. Despite this setback, the expedition was a success. On stardate 46048, Riker was commended by Captain Jean-Luc Picard for exceptional service with the citation reading, "Commander Riker's leadership skills and his scientific abilities were key factors in this mission." (TNG: "Future Imperfect")

According to the script, the pronunciation for Onias was "OH-nye-is". [1]

For the remastered episode of "Future Imperfect", the original okudagram of Riker's service record was replaced by a new graphic. This expedition was mentioned in that graphic.
