La Terre Vue de la planète Mars la sonde Curiosity. La distance entre Mars et la Terre est de 160 millions de km. La caméra en haut du mât du robot a pris la photo 80 minutes après le coucher du soleil. la Terre est vue comme un point, une étoile , et la Lune est visible comme un point plus faible encore et en dessous.
This view of the twilight sky and Martian horizon taken by NASA's Curiosity Mars rover includes Earth as the brightest point of light in the night sky. Earth is a little left of center in the image, and our moon is just below Earth. Two annotated versions of this image are also available in Figures 1 and 2.
Researchers used the left eye camera of Curiosity's Mast Camera (Mastcam) to capture this scene about 80 minutes after sunset on the 529th Martian day, or sol, of the rover's work on Mars (Jan. 31, 2014). The image has been processed to remove effects of cosmic rays.
A human observer with normal vision, if standing on Mars, could easily see Earth and the moon as two distinct, bright "evening stars."
The distance between Earth and Mars when Curiosity took the photo was about 99 million miles (160 million kilometers).
NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology, Pasadena, manages the Mars Science Laboratory Project for NASA's Science Mission Directorate, Washington. JPL designed and built the project's Curiosity rover. Malin Space Science Systems, San Diego, built and operates the rover's Mastcam.
