Nasa's Lunar Reconnaissance Orbiter (LRO) recently captured the exclusive view of Earth from the spacecraft's vantage point in orbit around the moon and it is one of the most spectacular images of our planet ever taken. The image exposes Earth seeming to rise above the craters of the lunar horizon. Noah Petro, Deputy Project Researcher for LRO at NASA's Goddard Space Flight Center in Greenbelt, said “The image is simply stunning.The image of the Earth evokes the famous 'Blue Marble' image taken by Astronaut Harrison Schmitt during Apollo 17, 43 years ago, which also showed Africa prominently in the picture.”
Taking an image of the Earth and moon with LRO's Lunar Reconnaissance Orbiter Camera (LROC) device is quite a difficult task.
First the spacecraft must be turned to the side (in this situation 67 degrees), then the spacecraft swings with the course of travel to maximize the width of the lunar horizon in LROC's Narrow Angle Camera image.
This all takes place while LRO is roaming faster than 3,580 miles per hour (over 1,600 meters per second) relative to the lunar surface below the spacecraft.
