EPOCh Observations: NASA EPOXI’s Spacecraft Observes the Earth-Moon System

“As part of the EPOXI mission’s objectives to characterize the Earth as a planet for comparison with planets around other stars, the spacecraft looked back at Earth collecting a series of images. In the left image the Earth-Moon system is seen with the Moon beginning its transit in front of Earth. It was taken on May 29, 2008 through three filters: blue, green and orange, centered at 450, 550 and 650 nm respectively, while the spacecraft was 0.33 AU (49,367,340 km and 30,675,43 miles) from Earth. The image on the right is a simulation showing the view of Earth from the spacecraft’s perspective.”
