Mosaic of four images taken by Rosetta’s navigation camera on September 19, 2014, at 28.6 km from the center of 67P/Churyumov-Gerasimenko. The images used for this mosaic were taken in sequence as a 2x2 raster over a 20 minute period, meaning that there is some motion of the spacecraft and rotation of the comet between the images.

This image of an impact crater in the Sirenum Fossae region of Mars was taken by NASA’s Mars Reconnaissance Orbiter on March 30, 2015. The crater is approximately 3,300 feet (1-km) wide and appears relatively recent as it has a sharp rim and well-preserved ejecta. The steep inner slopes are carved by gullies and include possible recurring slope lineae on the equator-facing slopes. Image credit: NASA / JPL / University of Arizona / Alfred McEwen.

This view of Pluto, based on the latest images to be downlinked from NASA’s New Horizons spacecraft, shows what you would see if you were approximately 1,100 miles (1,800 km) above Pluto’s equatorial area, looking northeast over the dark, cratered, named Cthulhu Regio toward the bright, smooth, expanse of icy plains called Sputnik Planum. The entire expanse of terrain seen in this image is 1,100 miles (1,800 km) across. Image credit: NASA / Johns Hopkins University Applied Physics Laboratory / Southwest Research Institute.

This panoramic image of Pluto highlights dwarf planet’s varied terrains and extended atmosphere. The scene measures 780 miles (1,250 km) across. The smooth expanse of Sputnik Planum (right) is flanked to the west (left) by rugged mountains up to 11,000 feet (3.5 km) high, including Norgay Montes in the foreground and Hillary Montes on the skyline. To the right, east of Sputnik, rougher terrain is cut by apparent glaciers. The backlighting highlights over a dozen layers of haze in the atmosphere of Pluto. The image was taken from a distance of 11,000 miles (18,000 km) to Pluto. Image credit: NASA / Johns Hopkins University Applied Physics Laboratory / Southwest Research Institute.

This illustration is a speculative representation of the interior of Enceladus with a global ocean between its rocky core and icy crust. The thickness of layers shown here is not to scale. Scientists determined that the slight wobble of the moon as it orbits Saturn is much too large for the moon to be frozen from surface to core. The wobble, technically referred to as a libration, reveals that the crust of Enceladus is disconnected from its rocky interior. Image credit: NASA / JPL-Caltech.

This colorful view of Mercury was produced by using images from the color base map imaging campaign during MESSENGER’s primary mission.

This image from NASA’s Galileo spacecraft shows Io. There are rugged mountains several miles high, layered materials forming plateaus, and many irregular depressions called volcanic calderas. Several of the dark, flow-like features correspond to hot spots, and may be active lava flows. There are no landforms resembling impact craters, as the volcanism covers the surface with new deposits much more rapidly than the flux of comets and asteroids can create large impact craters. The picture is centered on the side of Io that always faces away from Jupiter; north is to the top. Image credit: NASA / JPL / University of Arizona.
