Spaceship Earth and the Search for Intelligent Life

This program shows how the ecological health of the planet is being monitored from space,
as it examines issues such as the deterioration of the ozone layer, global warming, melting
polar ice caps, and the effects of solar winds. The possibility of life on other planets is
seriously considered in discussions that propose the possible existence of microbes on Mars,
and even more advanced organisms beneath the ice crust of the oceans of Jupiter’s moon,
Europa. (20 minutes, color)
