the self sustaining ecosphere is permanently sealed within this hand-blown glass sphere. Its careful balance of air, water, plant and animal life was developed as the result of years of NASA research into self-sustaining, bio-regenerative systems where the equilibrium must be maintained for long periods of time. Inside, tiny shrimp feed on bacteria that metabolize organic waste into nutrients for the algae which, in turn, photosynthesize the oxygen needed for the shrimp and bacteria to survive. I WANT ONE!!!
NASA ECHO II S-131 // From Wikipedia: "Project Echo was the first passive communications satellite experiment. Each of the two American spacecraft, launched in 1960 and 1964, was a metalized balloon satellite acting as a passive reflector of microwave signals. Communication signals were bounced off of them from one point on Earth to another."
