This new image of an area on Pluto’s largest moon Charon has a captivating feature — a depression with a peak in the middle, shown here in the upper left corner of the inset. The image shows an area approximately 240 miles (390 kilometres) from top to bottom, including few visible craters. The image was taken at approximately 10:30 UTC (11:30am BST) on 14 July 2015, about 1.5 hours before closest approach to Pluto, from a range of 49,000 miles (79,000 kilometres).

This image is heavily compressed; sharper versions are anticipated when the full-fidelity data from New Horizons’ Long Range Reconnaissance Imager (LORRI) are returned to Earth.
The rectangle superimposed on the global view of Charon shows the approximate location of this close-up view.
The image was taken at approximately 6:30am EDT on 14 July 2015, about 1.5 hours before closest approach to Pluto, from a range of 49,000 miles (79,000 kilometres).
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.
NASA’s New Horizons spacecraft doesn’t pass Pluto until July 14th — zipping by about 7,800 miles (12,500 kilometres) above the surface of the dwarf planet after a journey of almost 3 billion miles — but the mission team is making tantalising new discoveries as the piano-sized probe bears down on the Pluto system.
