It is 1994, and in the desert near Tillman, Arizona, a grand experiment involving the future of humanity is underway. As climate change threatens the earth, eight scientists dubbed the "Terranauts" have been selected to live under glass in E2, a prototype of a possible off-earth colony. Closely monitored by an all-seeing Mission Control, this New Eden is the brainchild of ecovisionary Jeremiah Reed, for whom the project is both an adventure in scientific discovery and a momentous publicity stunt. His young, strapping Terranauts must impress watchful visitors and a skeptical media curious to see if E2’s environment will somehow be compromised, forcing the Ecosphere’s seal to be broken --- and ending the mission in failure.
