Surface photographs from the Soviet Venera 9 and 10 spacecraft. These images were obtained on 22 and 25 October 1975. The surface of Mercury is shrinking faster than previously thought, photos from a NASA spacecraft orbiting the tiny planet reveal. Pour rappel, et pour situer ces images dans leur contexte, Mercury est situé dans le département de la Savoie de la région Rhône-Alpes et a une surface de 22.33 km ² pour une population de 2 710 habitants.
Such features indicate a …
The two spacecraft successfully landed a descent craft on 16 and 23 October 1975. Mercury Mosaic #2 This mosaic, also by the Mariner 10 spacecraft on the 29 March 1974, was taken while it retreated from the planet. [First Photos of Mercury from Orbit (Gallery) ] Less common are graben, depressed troughs that form when the surface between two parallel faults drops down. Mercury Dual Imaging System (MDIS) 1979x887x3: PIA19413: Wrinkles on Mercury Full Resolution: TIFF (1.759 MB) JPEG (423.3 kB) 2015-04-16: Mercury: MESSENGER: Mercury Dual Imaging System (MDIS) 3005x2105x3: PIA19412: (Size: 180K) Again consisting of 18 images, these images show somewhat more of the illuminated surface. Mercury Photos Reveal Strange 'Pie Crust' Surface Wrinkle ridges and depressed troughs combine in this depressed crater in the Goethe basin on Mercury. The first comprehensive survey of the surface of Mercury by NASA's MESSENGER spacecraft shows that planet's crust has contracted as it cooled by as much as 4.4 miles (7 kilometers), significantly more than previous estimates.
Voici les photos de la ville de Mercury et des alentours. The troughs, up to 2 kilometers wide, crosscut the outer ridge ring. The Soviet Venera 9 and 10 spacecraft were launched on 8 and 14 June 1975, respectively, to do the unprecedented: place a lander on the surface of Venus and return images. Mercury is the closest planet to our Sun, the smallest of the eight planets, and one of the most extreme worlds in our Solar Systems.
