MapCam Color Composite of Earth and Moon Taken After EGA
This color composite image of Earth and the Moon was taken Oct. 2, 2017, 10 days after OSIRIS-REx performed its Earth Gravity Assist maneuver, using MapCam, the mid-range scientific camera onboard the spacecraft. The distance to Earth was approximately 3,180,000 miles (5,120,000 km)—about 13 times the distance between the Earth and Moon.
MapCam, part of the OSIRIS-REx Camera Suite (OCAMS) operated by the University of Arizona, has four color filters. To produce this image, three of them (b, v and w) were treated as a blue-green-red triplet, co-registered and stacked. The Earth and Moon were each color-corrected, and the Moon was “stretched” (brightened) to make it more easily visible.
