Video Shows New Horizon's Best Close-Up Of Pluto's Surface Ever

Mosaic Strip of Detailed Images Taken By NASA's New Horizon

A YouTube video released by NASA shows the most detailed view of Pluto's surface that humans have ever seen.

The video includes all of the highest-resolution images taken by the NASA's New Horizons spacecraft of Pluto's surface as it flew past the icy 'planet' last year. These images give 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.  

“This new image product is just magnetic,” said Alan Stern, New Horizons principal investigator from Southwest Research Institute, Boulder, Colorado. “It makes me want to go back on another mission to Pluto and get high-resolution images like these across the entire surface.”



The video consists of a mosaic strip with a resolution of about 260 feet (80 meters) per pixel extending across the hemisphere that faced the probe.  The view extends from the “limb” of Pluto at the top of the strip, almost to the “terminator” (or day/night line) in the southeast of the encounter hemisphere, seen below. The width of the strip ranges from more than 55 miles (90 kilometers) at its northern end to about 45 miles (75 kilometers) at its southern point. 

The perspective changes greatly along the strip: at its northern end, the view looks out horizontally across the surface, while at its southern end, the view looks straight down onto the surface.

The video moves down the mosaic from top to bottom, offering new views of many of Pluto’s distinct landscapes along the way. Starting with hummocky, cratered uplands at top, the view crosses over parallel ridges of “washboard” terrain, chaotic and angular mountain ranges, cellular plains, coarsely “pitted” areas of sublimating nitrogen ice, zones of thin nitrogen ice draped over the topography below, and dark mountainous highlands scarred by deep pits.
