The press descends upon the domestic lives of the astronauts. Shepard and Gordo wilt under the limelight while Glenn thrives. Glenn secures a deal with Life Magazine that grants exclusive access to all seven astronauts in return for life-altering compensation. By the time the astronauts arrive in Florida to begin work, even Shepard has come to understand the power they now hold.

JFK sends a science committee to Cape Canaveral to assess the validity of the space program. Glenn, burning from the results of the peer vote, drafts letters to politicians complaining that Shepard is morally unfit to be the first man in space. But matters of internal power plays and a skeptical president are soon dwarfed by news out of Russia that could be the nail in Project Mercury’s coffin.

On the Eve of the flight, Louise learns of Shepard’s affair in Tijuana. Trudy watches Gordo crack a joke about women astronauts on television. Glenn awaits the humiliating moment when the world will finally learn he won’t be first. Tensions reach a breaking point when Shepard and Glenn are forced together in a pressure cooker of weather delays, marital discord, and a circus of reporters.
