"Жою операциясы: Ғылыми-қияли саяхат"

"Operation Annihilate!" is the twenty ninth and final episode of the first season of the American science fiction television series Star Trek. Written by Steven W. Carabatsos and directed by Herschel Daugherty, it was first broadcast April 13, 1967. In the episode, the crew of the Enterprise must find a way to exterminate behavior altering parasites that have taken over the bodies of residents of a Federation colony, including Captain Kirk's brother, Sam, and family. The episode is popular for revealing new facts about Vulcan physiology.

The USS Enterprise is tracking a path of mass insanity that has affected several planets, causing the collapse of their civilizations. They approach Deneva, a Federation colony where Captain Kirk's brother, Sam, has been stationed along with Sam's wife Aurelan and son, Peter. After entering the system, they try to stop a ship as it dives into the local sun, its pilot raving about being "free" before the ship is destroyed. Transporting to Deneva's main city, Kirk, First Officer Spock, Chief Medical Officer Dr. McCoy and a security detail find the town quiet. A group of men armed with clubs try to warn the landing party away, and then attack. Kirk has the men stunned, but McCoy finds that their brains are still being violently stimulated. The party locates the Kirk family home; Sam (played by William Shatner) is dead, while Aurelan (Joan Swift) acts irrationally before passing out and Peter (Craig Hundley) is comatose. Kirk and McCoy return with the survivors to Enterprise, where McCoy finds they are suffering from a condition similar to that of their attackers. McCoy gives both painkillers, and Aurelan wakes briefly to tell Kirk of horrible "things" spreading from planet to planet, using others' bodies to build ships. Kirk returns to the planet and joins Spock in search for these entities. They find a number of single celled creatures attached to the walls and ceiling of one building. The creatures fly, and attempt to attack the humans; the landing party finds they are nearly immune to phaser fire. One makes contact with Spock before Kirk can pry it off, and Spock falls in pain. They transport back to the Enterprise, and McCoy determines that the creature has injected some of its tissue into Spock's spinal column; it will be impossible to remove surgically. When Spock regains consciousness, he attempts to take control of the ship but McCoy sedates him in time. Later, Spock apologizes to Kirk and asserts that his mental discipline can control the pain, but that he must return to the surface to acquire a specimen to study. Kirk and McCoy agree, and Spock, on return to the colony, is able to stun a creature. Returning to the Enterprise, Spock and Kirk determine that the creatures are part of a hive mind. Spock and McCoy fail in their attempts to destroy the creature. Kirk holds a senior staff meeting, asserting they must find a solution before the creatures reach the next inhabited planet, holding over a million people; a solution that does not kill the hosts. Kirk recalls the ship's pilot stating that he was free before diving into the sun, and suspect the sun's properties may harm the creatures. He realizes that they have not tried visible light as a means to defeat the creatures. An initial test of blinding light results in the death of the specimen in sick bay. Spock then volunteers to be exposed to intense light, without eye protection, to prove that a creature infecting a host can be killed. Though the test is successful, Spock is now blind. Analysis of the initial test shows that only ultraviolet light was necessary to kill the creature. The Enterprise floods the colony with ultraviolet light from an array of satellites, killing the creatures on the planet and purging the parasites from the survivors. As the Enterprise prepares to leave orbit, Spock reveals that his Vulcan inner eyelids had prevented permanent blindness and that he can see again.

The script, which was written by Steven W. Carabatsos, was originally titled "Operation: Destroy". Aurelan was a Denevan woman in love with a man named Kartan, and it was Kartan who flew the ship into the Denevan sun in the cold open sequence. Aurelan's father was also a major character in the teleplay, and the two colonists were not infected by the "Denevan neural parasites". Instead, they helped Dr. McCoy and Mr. Spock with the research into how light could destroy the parasites. The script did not originally end with the Enterprise crew using light to destroy the parasites. Instead, the ship learns the location of the aliens' home world, and destroys the central controlling "brain" located there. Author James Blish used this draft of the script when adapting the episode for print, and this ending appears in the chapter "Operation Annihilate!" in the anthology Star Trek 2. This was the first episode of the series to be directed by Herschel Daugherty. Daugherty would later direct Season Three's "The Savage Curtain" as well. It was also the first appearance in Star Trek for child actor Craig Hundley, who played Peter Kirk. He would also portray Tommy Starnes in the third season episode "And the Children Shall Lead". Location shooting occurred in two places. The scene where the Enterprise landing party beams down to the surface was filmed at the TRW campus, Space Park (now Northrop Grumman Aerospace Systems) in Redondo Beach, California. The entrance of Sam Kirk's laboratory is the cafeteria in bldg. S at Space Park. The exterior of Sam Kirk's laboratory, which features white pylons, is Schoenberg Hall at the University of California, Los Angeles. The episode aired on April 13, 1967, and was the final episode to air in the series' first season. One scene did not make it into the episode. This scene came at the end of the story, and featured Peter Kirk (dressed in a command division tunic) sitting in the captain's chair on the bridge while his uncle, James T. Kirk, agrees to let him return to Deneva to live with Sam Kirk's research partner and friend. Although filmed, it was edited out due to time constraints. This left actor Hundley with no lines in the finished episode; the character of Peter Kirk spends the entire show unconscious. It also left the episode with no explanation of what becomes of Peter.

Zack Handlen of The A. V. Club gave the episode a 'B+' rating, describing it as "a little rocky in places" but otherwise praising the alien menace and Nimoy's acting. In 2016, TVLine ranked this as having one of the top twenty moments of Star Trek, noting the terrifying moment when the alien attacks Spock.

Galaxie 500, an American alternative rock band, wrote a song about the episode for their 1990 album This Is Our Music. The song was titled "Spook," but the band secretly used the title "Spock" since the lyrics referred to Spock's blindness in this episode:

Rock band Powerman 5000 sampled Aurelan's line, "They came Things ! HORRIBLE things!" from this episode for the beginning of their song, "Public Menace, Freak, Human Fly," the first track on their Mega!! Kung Fu Radio album.
