"Home" is the ninth episode of the first season of Stargate Atlantis.

Plot
Upon exploring the planet M5S-224, Dr. Rodney McKay discovers that the Stargate draws its energy from the atmosphere, and believes that this would be enough energy to power up a wormhole to Earth. After consulting Weir, the team decides to dismantle the control crystal in Atlantis and transport it to the planet in order to dial an eight chevron to the Milky Way galaxy. The wormhole connects, and Stargate Command tells them that it is alright to travel back to Earth since the Prometheus is capable of reaching the Pegasus Galaxy in a couple of months thanks to the installation of Asgard hyperdrives. Upon returning to Earth, they find out that the Prometheus has had an accident and is not capable of transporting them back to Atlantis.

Each team member slowly begins to realize that things are not as they seem. John Sheppard sees friends that had previously died in Afghanistan when he was serving with them, Dr. Weir is told by Gen. George Hammond that Atlantis will now become a full military and Sheppard is strangely in support of this. In his own reality, McKay notices that his scientific results are coming out as gibberish. As each team member comes to the realization that this Earth is not real, they find themselves in the embarkation room at Stargate Command with Gen. Hammond. But it is not the real Hammond, but rather a being of the original planet, which McKay mistook for highly charged mist. Mist-Hammond tells them that he had to create hallucinations for each team member to stop them from dialing the Stargate and currently they are unconscious. Since Teyla had no memories of Earth, she had to share Sheppard's memory. For many years, travelers had come through the Stargate and the unstable vortex effectively killed millions of mist beings. McKay realizes if they are unconscious, without food or water, they would eventually die. Mist-Hammond suggested that they return to their fantasies. Weir convinces him that they will not dial Earth, but head back to Atlantis instead and they are released from the hallucinations.
