2010 (episode)

"2010" is the sixteenth episode of the fourth season of Stargate SG-1.

Plot
The episode begins in medias res with Sam breakfasting with her husband Joe as they discuss their fertility problems. They also mention the Aschen, an advanced civilization who possess a very high grade of medical technology.

It turns out that the year is 2010, a 10-year jump into the future from the previous Stargate episode. Earth has transformed into a seeming paradise of long life and perfect health thanks to an alliance with the Aschen Confederation. It is the 10-year anniversary of SG-1 first encountering the Aschen, and there is going to be a ceremony commemorating the event. The Stargate now serves as a public gateway to other worlds and stands in the J.R. Reed Space Terminal. With the help of the Aschen, the Goa'uld have been defeated; the president is SG-1 nemesis Robert Kinsey. During the ten year anniversary ceremonies, the former SG-1 members are all present—minus Jack O'Neill. It also turns out that General Hammond is dead.

At this point in time, Sam and her husband, Senator Joe Faxon, are trying to get pregnant, but so far no luck. Their doctor, an Aschen, says there's nothing wrong with either of them and that they should just keep trying. When she tells Janet, Janet asks Sam to come by her office for an examination. Janet mentions that she is bored, given the near absence of disease thanks to Aschen medical technology. Sam agrees to be examined by her, and Janet makes a shocking discovery: Sam has been sterilized. She'll never be able to have children. Sam is devastated, not only because she can't have children, but because her Aschen doctor lied to her by telling her there was nothing wrong with her. Both wonder if this problem has occurred anywhere else in the world. They use the Aschen computer at Sam's lab to do a search.

Sam and Janet soon discover a dark secret: the Aschen have made over 90% of humans infertile, allowing them to bloodlessly take over the earth. They appear to have killed General Hammond when he became suspicious.

The former members of Stargate Command and SG-1 realize that it will be impossible to defeat the Aschen, so their best hope of victory lies in preventing Earth from ever meeting the Aschen. Using the advanced sensors the Aschen have given Earth, they pinpoint when a massive solar flare will happen, allowing them to repeat the same form of time travel they used previously to travel to and from 1969. They plan to send a warning to the past, using the centrally located, very public, Aschen-controlled Stargate.

First, they must go to great lengths to obtain a GDO in order to cause Stargate Command to open the iris. In the course of this, Sam discovers that her husband knew about the Aschen plan to decrease human fertility, though they had told him they would only make 1/3 of the population infertile. In contrast, O'Neill never trusted the Aschen, and is bitter that his word was ignored. After initially rebuffing the former SG-1 team when they ask for his help, he joins them in carrying out their plan. Sam must ask her husband, who is an ambassador to the Aschen, to steal it for them, because the only remaining GDO is in the Oval Office, on President Kinsey's desk. He agrees to aid them in exchange for the paternalistic promise that Carter be kept out of the final assault on the Stargate.

To get control of the Stargate, they enlist the help of Teal'c and another Jaffa. They are able to break through the strong defense measures surrounding the Stargate and dial the gate. However, as the former SG-1 members try to send their hand-written note through the gate, they are killed one by one, with each getting a bit closer to the gate. After the deaths of Teal'c, Jack, and Daniel, Sam breaks away from her husband and rushes to the Stargate. As she is cut down by the lasers, she manages to throw the bloodied note, written by O'Neill, through the gate. Janet is the only survivor as she escaped through the Stargate to Chulak before the mission began.

Back in 2000, Stargate Command receives an incoming transmission, accompanied by an SG-1 IDC, and through the gate comes a small, crumpled paper note. Written on it, in O'Neill's own handwriting (and with spots of O'Neill's blood on it as well), is a simple message: "UNDER NO CIRCUMSTANCES GO TO P4C-970, COLONEL JACK O'NEILL". General Hammond orders P4C-970 locked out of the dialing computer to prevent the planet from ever being contacted.
