Push in from the far side of the Moon to Apollo-8 take the "Earthrise" photo; then push in to NASA's Earth observing fleet in 1970 (the first Earth Day), then transition to the Earth observing fleet in 2020 (the 50th anniversary of Earth Day) This video is also available on our YouTube channel.
This visualization was created as an introductory shot to video celebrating the 50th anniersary of Earth Day. The camera approaches the moon from the far side, with Earth behind the moon. The camera moves over the limb revealing Apollo-8, when Bill Anders took the iconic "Earthrise" photo that inspired Earth Day and the environmental movement.
The camera then pushes in quickly to the Earth revealing the Earth observing spacecraft that were in orbit in 1970, the year of the first Earth Day. Finally, the orbits from other years are flashed on until we reach the orbits for 2020, the 50th anniversary of Earth Day.
