"Daedalus" is the tenth episode of the fourth season of the American science fiction television series Star Trek: Enterprise. Set in the 22nd century, the series follows the adventures of the first Starfleet starship Enterprise, registration NX-01. In this episode, as the crew of Enterprise help Doctor Emory Erickson (Bill Cobbs) conduct experimental transporter tests, a dangerous anomaly is detected on board. It was the second script written by Alan Brennert and Ken LaZebnik, and was directed by David Straiton - his second of the season. "Daedalus" was a bottle episode which used only the standing sets. Show runner Manny Coto had sought to create an origin story for the transporter with "Daedalus", but was not pleased with either the script or the completed episode.

Tucker assists Erickson with the test, but is brushed aside when he seeks to learn more about the technology. Following a successful trial-run, which sets a new record for the longest transport ever conducted, Tucker confides in Archer that many of the upgrades and modifications to the ship's power systems were not necessary for the test. The "photonic ghost" reappears, and T'Pol manages to visually scan it, revealing that it is Erickson's long-lost son. Archer now
