The following individuals made up the science party assigned to the observation station on Psi 2000. The USS Enterprise was assigned to pick up the six observers in early 2266, when they were all discovered to be dead.
Engineer []
This engineer was found dead in the console room of the observation station as a result of his polywater intoxication. Following his death, it was reported by Joe Tormolen that he died at his post with all life systems off, "frozen there like he didn't care." (TOS: "The Naked Time")
Man in shower []
This crewman was found frozen to death in a shower while fully clothed. (TOS: "The Naked Time")
Details of this crewman's demise was later vaguely remembered by Commander William T. Riker in 2364, when a crewwoman aboard the SS Tsiolkovsky experienced a similar death. He requested the assistance of Lieutenant Commander Data in locating the information in the USS Enterprise-D's library-computer information, based solely the recollection "a vague memory of reading somewhere about someone taking a shower in his or her clothing," believing there to be a connection between the two incidents. (TNG: "The Naked Now")
Phaser pistol shooter []
This crewman was found dead with a phaser pistol in his hand, having "used the computer room as if it were an amusement gallery," according to Spock. (TOS: "The Naked Time")
Woman in corridor []
This crew woman was strangled to death in the corridor near the console room. (TOS: "The Naked Time")
