![]() ![]() Lockheed Martin Space Systems, Denver, built the orbiter and collaborates with JPL to operate it. NASA’s Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Mars Reconnaissance Orbiter Project for NASA’s Science Mission Directorate, Washington. The University of Arizona, Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp. With HiRISE and five other instruments, the Mars Reconnaissance Orbiter has been investigating Mars since 2006. When the component images were taken, Mars was about 127 million miles (205 million kilometers) from Earth. In the image, the reddish feature near the middle of the face of Earth is Australia. Earth and the moon appear closer than they actually are in this image because the observation was planned for a time at which the moon was almost directly behind Earth, from Mars’ point of view, to see the Earth-facing side of the moon. That star, known as Earendel, was discovered last year by the Hubble Space Telescope.It has taken 12.9 billion years for Earendel's light to reach Earth, meaning the star was shining less than a. The distance between Earth and the moon is about 30 times the diameter of Earth. The combined view retains the correct positions and sizes of the two bodies relative to each other. ![]() The moon is much darker than Earth and would barely be visible if shown at the same brightness scale as Earth. For presentation, the exposures were processed separately to optimize detail visible on both Earth and the moon. The images were taken to calibrate HiRISE data, since the reflectance of the moon’s Earth-facing side is well known. 20, 2016, by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter. The image combines two separate exposures taken on Nov. 20, 2016, by the HiRISE camera on NASA's Mars Reconnaissance Orbiter, with brightness adjusted separately for Earth and the moon to show details on both bodies.įrom the most powerful telescope orbiting Mars comes a new view of Earth and its moon, showing continent-size detail on the planet and the relative size of the moon. Here is a view of Earth and its moon, as seen from Mars. ![]()
