Scientists released a sneak peek of Pluto taken by New Horizons around 2000 GMT Monday at a range of 766,000 kilometres (476,000 miles), about 16 hours before closest approach.

This feature appears to be a frozen, former lake of liquid nitrogen, located in a mountain range just north of Pluto’s informally named Sputnik Planum. Captured by the New Horizons’ Long Range Reconnaissance Imager (LORRI) as the spacecraft flew past Pluto on 14 July 2015, the image shows the possible lake to be about 20 miles (30 kilometres) across.
To help mission scientists understand the diversity of Pluto’s terrain and to piece together how the dwarf planet’s surface has formed and evolved over time, NASA’s New Horizons mission scientists have started constructing geological maps. The base map for this interpretation is a mosaic of 12 images obtained by the spacecraft’s Long Range Reconnaissance Imager (LORRI).
A mosaic strip just released by the New Horizons team now includes all of the highest-resolution images taken by the NASA probe. The mosaic affords scientists and the public the best opportunity to examine the fine details of the various types of terrain on Pluto, and determine the processes that formed and shaped them.
