The Nenebek (NAR-21166) was a Nenebek-type sublight mining shuttle that was in service in the independent Pentarus system in the mid-24th century. Constructed sometime in the mid-23rd century, this shuttle was used to ferry people between various starships and planets. Nenebek was the property of Captain Dirgo who had logged almost 10,000 hours in this shuttle, and had modified the maneuvering thrusters into an unusual configuration.
In 2367, the authorities on Pentarus V requested a negotiator from the Federation to mediate a dispute between salenite miners, and Captain Jean-Luc Picard was selected for this role. The Nenebek was dispatched to rendezvous with the USS Enterprise-D.
Before transporting Captain Picard and his assistant, Wesley Crusher to Pentarus V, Chief Engineer Geordi La Forge conducted safety and operational inspections of the shuttle, and deemed the shuttle was safe for flight. La Forge noted that the configuration of the thrusters were rigged in a way he hadn't seen before.
During flight, the shuttle's port thruster module exploded which resulted immediately in damage to the port thruster quad, the communications systems, and the guidance coupling. When the guidance coupling was damaged, severing it from the computer, the shuttle's navigation systems ceased to function forcing Dirgo to switch to manual control. With Pentarus V fifty million kilometers away, Dirgo, with the help of Picard and Crusher, piloted the shuttle into a controlled crash landing on Lambda Paz, one of the moons of Pentarus III.
After the crash landing, an examination of the Nenebek was conducted by Dirgo, and Picard salvaged the shuttle for supplies. Dirgo determined that that the shuttle's systems were destroyed which meant that he couldn't open a channel with the communications system, that the location transponder was not transmitting the location of the crashed shuttle, and that the replicator wouldn't be able to replicate food and water. The only supplies recovered from the shuttle by Picard were medical, as the Nenebek wasn't equipped with emergency rations. Along with the medical supplies, the survivors were able to recover weapons from the shuttle. Before leaving the crash site, the survivors fashioned a crude arrow on the surface of the moon from parts of the shuttle indicating the direction of their travel.
Later, the Enterprise-D located the wreckage of the Nenebek and the arrow, and, by following the arrow, were able to recover both Crusher and Picard. By the time of the rescue, Dirgo was dead. Both the captain and his shuttle were left behind on Lambda Paz. (TNG: "Final Mission")
