The Planets, an A&E educational series, explores the universe through previously unreleased NASA footage, consultations with scientific specialists including astronomers and astronauts, and telescope and satellite images combined with computer-generated graphics and effects. Vol. 2: Terra Firma presents the fascinating geological surfaces of Earth's neighbors: Jupiter, Mars, Venus, and Europa (a moon of Jupiter). It is appropriate for middle school and high school classes on science, technology, astronomy, and world history.
