Transformers: Dark of the Moon
In 1960, the Ark, a Cybertronian spacecraft carrying an invention capable of ending the war between Autobots and Decepticons, crash lands on the dark side of Earth's Moon and is detected by NASA. President John F. Kennedy authorizes a mission to put a man on the Moon as a cover for investigating the spacecraft. In 1969, the crew of Apollo 11 lands on the Moon and secretly inspects the Ark before returning to Earth.
In the present day, four years after Egypt,[a] the Autobots assist humanity in preventing major conflicts. During a mission to the site of the 1986 Chernobyl nuclear disaster in Ukraine to investigate suspected alien technology, the Autobots are attacked by Decepticon scientist Shockwave and his giant worm Driller. After the two escape, Optimus Prime discovers that the technology is a fuel cell from the Ark, thought to have been lost after escaping Cybertron. The Autobots travel to the Moon and discover Sentinel Prime, the Autobots' leader before Optimus, in a comatose state along with five Pillars he created as a means of establishing a "Space Bridge", a wormhole able to teleport matter between two points. On Earth, Optimus uses the energy of the Matrix of Leadership to revive Sentinel.
Meanwhile, Sam Witwicky lives with his new girlfriend, Carly Spencer but is unable to work with the Autobots. At his new job, co-worker Jerry Wang gives him information about the Ark, before being assassinated by the Decepticon Laserbeak. It is revealed that the Decepticons are murdering people connected to the American and Soviet space missions to the Ark. Sam contacts Seymour Simmons, and they locate two surviving cosmonauts, who reveal photos of hundreds of Pillars being stockpiled on the Moon. The Decepticons raided the Ark long before the Apollo 11 mission and intentionally left Sentinel and the five Pillars for the Autobots to find, knowing that Sentinel is the key to activating the Pillars. Meanwhile, Sam and the Autobots return Sentinel to their base. However, he betrays them by revealing that he made a deal with Megatron to ensure Cybertron's survival before killing Ironhide.
