New NASA Images Reveal Pluto’s Terrain

NASA has released incredibly detailed images of Pluto taken by the New Horizons spacecraft in July during its historic flyby.

The stunning photos reveal a complex and varied terrain on the icy dwarf planet.

The photos show the oldest terrain spotted on Pluto, which is heavily cratered as well as newer terrain characterized by icy plains.

“The surface of Pluto is every bit as complex as that of Mars,” said Jeff Moore, leader of the New Horizons Geology, Geophysics and Imaging team at NASA’s Ames Research Center, in a statement. “The randomly jumbled mountains might be huge blocks of hard water ice floating within a vast, denser, softer deposit of frozen nitrogen within the region informally named Sputnik Planum.”

The pictures, some at a resolution of up to 400 meters per pixel, show features like possible dunes, nitrogen ice flows and “networks of valleys that may have been carved by material flowing over Pluto’s surface,” according to a news release.

In the center of this 300-mile (470-kilometer) wide image of Pluto from NASA’s New Horizons spacecraft is a large region of jumbled, broken terrain on the northwestern edge of the vast, icy plain informally called Sputnik Planum, to the right. The smallest visible features are 0.5 miles (0.8 kilometers) in size. This image was taken as New Horizons flew past Pluto on July 14, 2015, from a distance of 50,000 miles (80,000 kilometers).

The image is dominated by the informally-named icy plain Sputnik Planum, the smooth, bright region across the center. This image also features a tremendous variety of other landscapes surrounding Sputnik.

There are also “chaotically jumbled” mountains NASA says may be similar to terrain seen on Jupiter’s moon, Europa.

“Seeing dunes on Pluto -- if that is what they are -- would be completely wild, because Pluto’s atmosphere today is so thin,” said William B. McKinnon, a GGI deputy lead from Washington University, St. Louis, in a statement. “Either Pluto had a thicker atmosphere in the past, or some process we haven’t figured out is at work. It’s a head-scratcher.”

Another source of surprise has been the revelation that Pluto’s thin atmospheric haze has many more layers than previously thought.
