New global map of Pluto

29 July 2015 Astronomy Now

The science team of NASA’s New Horizons mission has produced an updated global map of dwarf planet Pluto that includes all resolved images of the surface acquired 7-14 July 2015, up to 400 metres/pixel resolution. Many additional images are expected in autumn 2015 and these will be used to complete the global map.
