Data from that priceless, once in a lifetime flyby is now trickling back to Earth.
The ‘snakeskin’ feature on Pluto’s utterly bizarre surface was unveiled to “astonished” scientists scrutinizing the latest data dump received over the past week, that included images taken by the Ralph instruments Multispectral Visual Imaging Camera (MVIC).
Features as small as 0.8 miles (1.3 kilometers) are resolved in detail.
The MVIC image stretches about 330 miles (530 kilometers) across the ‘snakeskin’ like landscape composed of rounded and bizarrely textured mountains that are informally named Tartarus Dorsa and that borders the bodies day-night terminator.
It shows intricate patterns of blue-gray ridges and reddish material in between that are puzzling researchers.
“It’s a unique and perplexing landscape stretching over hundreds of miles,” said William McKinnon, New Horizons Geology, Geophysics and Imaging (GGI) team deputy lead from Washington University in St. Louis.
“It looks more like tree bark or dragon scales than geology. This’ll really take time to figure out; maybe it’s some combination of internal tectonic forces and ice sublimation driven by Pluto’s faint sunlight.”
The Ralph/MVIC image is actually a composite of blue, red and infrared images.
The image of Tartarus Dorsa reveals a “multitude of previously unseen topographic and compositional details. It captures a vast rippling landscape of strange, aligned linear ridges that has astonished New Horizons team members,” say officials.
NASA’s New Horizons spacecraft captured this high-resolution enhanced color view of Pluto on July 14, 2015. The image combines blue, red and infrared images taken by the Ralph/Multispectral Visual Imaging Camera (MVIC). Pluto’s surface sports a remarkable range of subtle colors, enhanced in this view to a rainbow of pale blues, yellows, oranges, and deep reds. Many landforms have their own distinct colors, telling a complex geological and climatological story that scientists have only just begun to decode.

Another wider angle global view of Pluto downlinked on Sept. 19 shows a new “extended color” view of Pluto with an the extraordinarily rich color palette of the planet.
“We used MVIC’s infrared channel to extend our spectral view of Pluto,” said John Spencer, a GGI deputy lead from Southwest Research Institute (SwRI) in Boulder, Colorado.
“Pluto’s surface colors were enhanced in this view to reveal subtle details in a rainbow of pale blues, yellows, oranges, and deep reds. Many landforms have their own distinct colors, telling a wonderfully complex geological and climatological story that we have only just begun to decode.”
The image resolves details and colors on scales as small as 0.8 miles (1.3 kilometers).
High-resolution images of Pluto taken by NASA’s New Horizons spacecraft just before closest approach on July 14, 2015, reveal features as small as 270 yards (250 meters) across, from craters to faulted mountain blocks, to the textured surface of the vast basin informally called Sputnik Planum. Enhanced color has been added from the global color image. This image is about 330 miles (530 kilometers) across. For optimal viewing, zoom in on the image on a larger screen.

Beyond MVIC, additional new images taken by New Horizons’ narrow-angle Long Range Reconnaissance Imager (LORRI) during the July 14 were downlinked on Sept. 20.
They focus on the Sputnik Planum ice plains on the left side of the famous heart shaped Tombaugh Regio feature and are the highest resolution yet – as seen below. The team added color based on the global MVIC map shown above.

Barely 5 or 6 percent of the 50 gigabits of data captured by New Horizons has been received by ground stations back on Earth.
“With these just-downlinked images and maps, we’ve turned a new page in the study of Pluto beginning to reveal the planet at high resolution in both color and composition,” added New Horizons Principal Investigator Alan Stern, of SwRI.
“I wish Pluto’s discoverer Clyde Tombaugh had lived to see this day.”
Stern says it will take about a year for all the data to get back. Thus bountiful new discoveries are on tap.

Just 15 minutes after its closest approach to Pluto on July 14, 2015, NASA’s New Horizons spacecraft looked back toward the sun and captured this near-sunset view of the rugged, icy mountains and flat ice plains extending to Pluto’s horizon – shown in this colorized rendition. The smooth expanse of the informally named icy plain Sputnik Planum (right) is flanked to the west (left) by rugged mountains up to 11,000 feet (3,500 meters) high, including the informally named Norgay Montes in the foreground and Hillary Montes on the skyline. To the right, east of Sputnik, rougher terrain is cut by apparent glaciers. The backlighting highlights more than a dozen layers of haze in Pluto’s tenuous but distended atmosphere. The image was taken from a distance of 11,000 miles (18,000 kilometers) to Pluto; the scene is 780 miles (1,250 kilometers) wide.

Imagine yourself as a once in a lifetime Plutonian tourist sailing along in a spartan spaceship and looking out the windows to breathtaking alien landscapes with cameras snapping away.
Now for the first time in human history, you can embark on a heretofore unimaginable flyover tour over Pluto – the most distant planetary system yet explored by an emissary from Earth, thanks to the team propelling NASA’s New Horizons spacecraft to the far flung reaches of our Solar System.
Just click on the video above and take the astounding aerial flyover tour above Pluto’s huge heart and the icy worlds wondrous array of tectonically active flow plains and majestic mountain ranges towering kilometers skyward to its thin hazy atmosphere.
The animation is a gift to humanity as seen from the perspective of the New Horizons probe as it flew past Pluto on July 14, 2015 at a distance of 50,000 miles (80,000 kilometers).
The new flyover video beautifully melds “art and science” – and is the brainchild of Stuart Robbins, a New Horizons research scientist at the Southwest Research Institute in Boulder, Colorado.
“I have used the latest images to produce an animation that shows what it might be like to take an aerial tour through Pluto’s thin atmosphere and soar above the surface that New Horizons explored,” Robbins explained in a blog posting.
The flyover animation is based on a stitched together mosaic of New Horizons images that were then rendered onto a sphere of Pluto. The animation and spherical mosaic were created by New Horizons team members using the initial batch of images taken by the LORRI (Long Range Reconnaissance Imager) camera and downloaded from the spacecraft as of Sept. 11, 2015.
“The mosaic …. provides an incredibly accurate portrayal of Pluto’s surface. It showcases …. the huge variety of terrain types that we see on Pluto.”
The flyover begins low over the heart shaped region of Pluto informally named Tombaugh Regio by the New Horizons team. The LORRI images at the starting point over the Norgay Montes mountain range have a resolution up to 400 meters per pixel at a altitude of only about 120 miles (200 kilometers). The resolution then changes to about 800 meters per pixel.
The animation concludes with images of approximately 2.1 kilometers per pixel as the apparent altitude increases tenfold to about 1,500 miles (2,500 kilometers) as viewers perspective changes from an up close view to one revealing Pluto’s disk rapidly growing to show about 80% of the hemisphere New Horizons flew closest to on July 14, 2015.
Here is Robbins explanation of the Plutonian terrain visible during your tourists eye view:
“Our tour starts low over the informally named Norgay Montes at a height of about 120 miles (200 kilometers). These jagged mountains rise almost 2 miles (3 kilometers) from the surrounding surface.”
“We head north over Sputnik Planum (bright area to the left) and Cthulhu Regio (dark area to the right). While Sputnik Planum is smooth at this pixel scale, it’s in marked contrast to Cthulhu Regio which has many large impact craters that indicate the Regio is much older. The differences in brightness are some of the largest natural brightness variations of any object in the solar system.”
“Our view steadily rises to a height of about 150 miles (240 kilometers) and turns to look east. From this point, we drift slowly to the east, with Pluto’s north pole to the left, Tombaugh Regio filling much of the middle of the view, and older, more cratered areas standing out in marked contrast to the younger glaciers of the “heart’s” left lobe, Sputnik Planum.”
“As we continue to fly, our flight path rises to more than 1,500 miles (2,500 kilometers) with the final view of most of the disk that New Horizons saw on July 14.”
Robbins role on the New Horizons science team is using the images “to map craters across the surfaces of Pluto and its largest moon, Charon, to understand the population of impactors from the Kuiper Belt striking Pluto and Charon.”
To see and study the whole disk of Pluto and the highest resolution view of the “heart” check out our global Pluto and Tombaugh Regio mosaics generated from raw images captured by New Horizons’ Long Range Reconnaissance Imager (LORRI) and stitched together by the image processing team of Marco Di Lorenzo and Ken Kremer.
New Horizon’s unveiled Pluto as a surprisingly vibrant and geologically active “icy world of wonders” as it barreled past the Pluto-Charon double planet system on July 14 at over 31,000 mph (49,600 kph) and collected unprecedented high resolution imagery and spectral measurements of the utterly alien worlds.
What are Pluto’s newly discovered plains and mountains composed of?
“The plains are made of nitrogen. But nitrogen is too soft a material to build mountains out of, even in Pluto’s weak gravity,” says New Horizons Principal Investigator Alan Stern of the Southwest Research Institute, Boulder, Colorado.
“So the mountains must be made of something else stronger. Rock and water ice are the two most likely possibilities. But they are most likely water ice.”
Here’s our colorized and annotated version of the recently released backlit view of Pluto taken 15 minutes after closest approach as New Horizons spacecraft looked back toward the sun and captured a near-sunset view of the rugged, icy mountains and flat ice plains extending to Pluto’s horizon.

Since the flyby, the team has been busy analyzing the science data returned thus far and “making some discoveries” says Stern.
“Pluto is showing us a diversity of landforms and complexity of processes that rival anything we’ve seen in the solar system.”
“If an artist had painted this Pluto before our flyby, I probably would have called it over the top — but that’s what is actually there.”
New Horizons gathered about 50 gigabits of data as it hurtled past Pluto, its largest moon Charon and four smaller moons.
New Horizons also discovered that Pluto is the biggest object in the outer solar system and thus the ‘King of the Kuiper Belt’.
The Kuiper Belt comprises the third and outermost region of worlds in our solar system.
Only about 5 to 6 percent has been downlinked to Earth so far. Stern says it will take about a year for all the data to get back.
So expect a year of endless treats and surprises from the ‘King of the Kuiper Belt’!
