This is an overview of the B612 Sentinel inner solar system mapping mission, announced by the B612 Foundation at a press conference on 6/28/12 at the California Academy of Sciences. The animations, constructed by the California Academy of Sciences Visualization Studio, were originally designed to play on the Academy's massive planetarium screen. This is a high-definition rendering of the much larger animation projected that day. The audio is raw audio of astronaut Ed Lu's explanation of the mission. It was recorded in real time during the event.
