The science team of NASA’s New Horizons mission has produced this global map of Pluto’s largest moon, Charon. The map includes all available resolved images of the surface acquired between 7-14 July 2015, at pixel resolutions ranging from 40 kilometres (24 miles) on the anti-Pluto facing hemisphere (left and right sides of the map), to 400 metres (1,250 feet) per pixel on portions of the Pluto-facing hemisphere – the side facing the New Horizons spacecraft when it flew past the dwarf planet – at map centre. Many additional images now stored on the spacecraft’s digital data recorders are expected to be transmitted “home” in later this year and these will be used to complete the global map. The map is in simple cylindrical projection, with zero longitude (the Pluto-facing direction) in the centre.
This enhanced colour mosaic combines some of the sharpest views of Pluto that NASA’s New Horizons spacecraft obtained during its 14 July flyby, revealing features smaller than half a city block on the dwarf planet’s surface. The wide variety of cratered, mountainous and glacial terrains seen here gives scientists and the public alike a breathtaking, super-high-resolution colour window into Pluto’s geology.
