These latest pictures are part of a sequence taken near New Horizons’ closest approach to Pluto, with resolutions of about 250-280 feet (77-85 meters) per pixel – revealing features less than half the size of a city block on the diverse surface of the distant planet. In these new images, New Horizons captured a wide variety of spectacular, cratered, mountainous and glacial terrains.

“New Horizons thrilled us during the July flyby with the first close images of Pluto, and as the spacecraft transmits the treasure trove of images in its onboard memory back to us, we continue to be amazed by what we see.”
Erosion and faulting has sculpted portions of Pluto’s icy crust into rugged badlands. The prominent 1.2-mile-high cliff at the top, running from left to upper right, is part of a great canyon system that stretches for hundreds of miles across Pluto’s northern hemisphere.

A video made from these images reveals amazing details on a world 3 billion miles away –
As do individual close-ups taken from the wider swath. The images are six times better than the resolution of the global Pluto map New Horizons obtained, and five times better than the best images of Pluto’s cousin Triton, Neptune’s large moon, obtained by Voyager 2 in 1989.
“Impact craters are nature’s drill rigs, and the new, highest-resolution pictures of the bigger craters seem to show that Pluto’s icy crust, at least in places, is distinctly layered,” said William McKinnon, deputy lead of the New Horizons Geology, Geophysics and Imaging team, from Washington University in St. Louis.
“Looking into Pluto’s depths is also looking back into geologic time, which will help us piece together Pluto’s geological history.”
These images were made with the telescopic Long Range Reconnaissance Imager (LORRI) aboard New Horizons, in a timespan of about a minute centered on 11:36 UT on July 14 – just about 15 minutes before New Horizons’ closest approach to Pluto – from a range of just 10,000 miles (17,000 kilometers.
