Space probe Entered orbit around dwarf planet Ceres in early 2015. Currently orbiting Ceres as of February 2017. First probe to Jupiter without atomic batteries, launched August 8, 2011. Chang'e 2 was deployed to orbit the Moon, visit Sun–Earth L2 Lagrangian point, and make a flyby of asteroid 4179 Toutatis. Along with "Pioneer 10", "Pioneer 11", and its sister space probe "Voyager 2", "Voyager 1" is now an interstellar probe. "Voyager 1" and "2" have both achieved solar escape velocity, meaning that their trajectories will not return them to the Solar System. Examples of space probe imaging telescope/cameras (focused on visible spectrum).
Mercury (planet) several meters. Not until the first space probe flew past Mercury did many of its most fundamental morphological properties become known. Moreover, recent technological advances have led to improved ground-based observations. In 2000, high-resolution lucky imaging observations were conducted by the Mount Wilson Observatory 1.5 meter Hale telescope. They provided the first views that resolved surface features on the parts of Mercury that were not imaged in the mission. Most of the planet has been mapped by the Arecibo radar telescope, with resolution, including polar deposits in shadowed craters of what may be water ice. Reaching Mercury from Earth poses
