Until barely two weeks ago, Pluto tantalized humanity for eight decades with mysteries we could only imagine – seen as just a point of light or fuzzy blob in the world’s most powerful telescopes.

Now the last explored planetary system in our solar system is being revealed for the first time in history to human eyes, piece by piece, in the form of the highest resolution flyover mosaics and movies of the alien surface ever available, now and for decades to come.

And it’s all thanks to the brilliant efforts of the scientists and engineers leading NASA’s New Horizons mission – which culminated in the first ever close encounter with Pluto and its five moons by a spacecraft from Earth on July 14, 2015.

With the resoundingly successful close flyby completed and the piano shaped New Horizons probe now looking in the rear view mirror, the scientific booty is raining down on receivers back on Earth. However it will take about 16 months to send all the flyby science data back to Earth due to limited bandwidth.

The first series of seven breathtaking high resolution surface images focusing on Pluto’s bright heart-shaped region, informally named ‘Tombaugh Regio’, has been stitched together into our new and wider view mosaic, shown above and below, by the image processing team of Marco Di Lorenzo and Ken Kremer.

Furthermore the New Horizons team has created a spectacular simulated flyover movie centered in the heart of Pluto’s huge ‘Heart’ at ‘Tombaugh Regio’, showing the stunning views including the incredibly recent ice flows and plains of ‘Sputnik Planum’ and monumental icy mountain ranges of ‘Norgay Montes’ and newly discovered ‘Hillary Montes.’

The mosaic and movie are compiled from the seven highest resolution images captured by NASA’s New Horizons LORRI imager during the history making closest approach flyby.

The LORRI images were taken from a distance of 48,000 miles (77,000 kilometers) from the surface of the planet about 1.5 hours prior to the closest approach at 7:49 a.m. EDT on July 14. The images easily resolve structures smaller than a mile across.

New Horizon’s unveiled Pluto as a surprising 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.

This annotated image of the southern region of Sputnik Planum illustrates its complexity, including the polygonal shapes of Pluto’s icy plains, its two mountain ranges, and a region where it appears that ancient, heavily-cratered terrain has been invaded by much newer icy deposits. The large crater highlighted in the image is about 30 miles (50 kilometers) wide, approximately the size of the greater Washington, DC area. Credits: NASA/JHUAPL/SwRI

The newly-discovered mountain range has been informally named Hillary Montes (Hillary Mountains) for Sir Edmund Hillary, who first summited Mount Everest with Tenzing Norgay in 1953. They rise about one mile (1.6 kilometers) above the surrounding plains, similar to the height of the Appalachian Mountains in the United States.

They are located nearby and somewhat north of another mountain range discovered first and named Norgay Montes (Norgay Mountains).

“For many years, we referred to Pluto as the Everest of planetary exploration,” said New Horizons Principal Investigator Alan Stern of the Southwest Research Institute, Boulder, Colorado.

“It’s fitting that the two climbers who first summited Earth’s highest mountain, Edmund Hillary and Tenzing Norgay, now have their names on this new Everest.”

The LORRI images show “extensive evidence of exotic ices flowing across Pluto’s surface and revealing signs of recent geologic activity, something scientists hoped to find but didn’t expect.”

Sputnik Planum is a Texas-sized plain, which lies on the western, left half of Pluto’s bilobed and bright heart-shaped feature, known as Tombaugh Regio.

The new imagery and spectral evidence from the Ralph instrument appears to show the flow of nitrogen ices in geologically recent times across a vast region. They appear to flow similar to glaciers on Earth. There are also carbon monoxide and methane ices mixed in with the water ices.

“At Pluto’s temperatures of minus-390 degrees Fahrenheit, these ices can flow like a glacier,” said Bill McKinnon, deputy leader of the New Horizons Geology, Geophysics and Imaging team at Washington University in St. Louis.

“In the southernmost region of the heart, adjacent to the dark equatorial region, it appears that ancient, heavily-cratered terrain has been invaded by much newer icy deposits.”

“We see the flow of viscous ice that looks like glacial flow.”

As of today, July 26, New Horizons is 12 days past the Pluto flyby and already over 15 million kilometers beyond Pluto and continuing its journey into the Kuiper Belt, the third realm of worlds in our solar system.

New Horizons discovered that Pluto is the largest known body beyond Neptune – and thus reigns as the “King of the Kuiper Belt!”

The science team plans to target New Horizons to fly by another smaller Kuiper Belt Object (KBO) as soon as 2018.

Flowing Ice, Exotic Mountains and Backlit Haze Highlight Pluto as Never Seen Before

Backlit by the sun, Pluto’s atmosphere rings its silhouette like a luminous halo in this image taken by NASA’s New Horizons spacecraft around midnight EDT on July 15. This global portrait of the atmosphere was captured when the spacecraft was about 1.25 million miles (2 million kilometers) from Pluto and shows structures as small as 12 miles across.

Spectacular imagery of huge regions of flowing ice, monumental mountain ranges and a breathtakingly backlit atmospheric haze showing Pluto as we’ve never seen it before, were among the newest discoveries announced today, July 24, by scientists leading NASA’s New Horizons mission which sped past the planet for humanity’s first ever up-close encounter only last week.

New Horizon’s revealed Pluto be an unexpectedly vibrant “icy world of wonders” as it barreled by the Pluto-Charon double planet system last Tuesday, July 14, at over 31,000 mph (49,600 kph).

The scientists publicly released a series of stunning new images and science discoveries at Pluto that exceeded all pre-flyby expectations.

“The images of Pluto are spectacular,” said John Grunsfeld, NASA’s associate administrator for the Science Mission Directorate, at today’s media briefing.

“We knew that a mission to Pluto would bring some surprises, and now — 10 days after closest approach — we can say that our expectation has been more than surpassed. With flowing ices, exotic surface chemistry, mountain ranges, and vast haze, Pluto is showing a diversity of planetary geology that is truly thrilling.”

New Horizons discovers flowing ices in Pluto’s heart-shaped feature. In the northern region of Pluto’s Sputnik Planum (Sputnik Plain), swirl-shaped patterns of light and dark suggest that a surface layer of exotic ices has flowed around obstacles and into depressions, much like glaciers on Earth.

Over 50 gigabits of data were collected during the encounter and flyby periods of the highest scientific activity in the most critical hours before and after the spacecrafts closest approach to Pluto, its largest moon Charon and its quartet of smaller moons.

Data from the flyby is now raining back to Earth, but slowly due to limited bandwidth of an average “downlink” of only about 2 kilobits per second via its two transmitters.

“So far we’ve seen only about 5% of the encounter data,” said Jim Green, director of Planetary Science at NASA Headquarters in Washington.

At that pace it will take about 16 months to send all the flyby science data back to Earth.

Among the top highlights is the first view ever taken from the back side of Pluto, a backlit view that humans have never seen before.

It shows a global portrait of the planets extended atmosphere and was captured when NASA’s New Horizons spacecraft was about 1.25 million miles (2 million kilometers) from Pluto. It shows structures as small as 12 miles across.

“The silhouette of Pluto taken after the flyby and show a remarkable haze of light representing the hazy worlds extended atmosphere,” Alan Stern, principal investigator for New Horizons at the Southwest Research Institute (SwRI) in Boulder, Colorado, said at the media briefing.

“The image is the equivalent of the Apollo astronauts Earth-rise images.”

“It’s the first image of Pluto’s atmosphere!” said Michael Summers, New Horizons co-investigator at George Mason University in Fairfax, Virginia, at the briefing.

“We’ve known about the atmosphere for over 25 years,” and now we can see it. There are haze layers and it shows structure and weather. There are two distinct layers of haze. One at about 30 miles (50 kilometers) and another at about 50 miles (80 kilometers) above the surface.”

“The haze extend out about 100 miles! Which is five times more than expected.”

The image was taken by New Horizons’ high resolution Long Range Reconnaissance Imager (LORRI) while looking back at Pluto, barely seven hours after closest approach at 7:49 a.m. EDT on July 14, and gives significant clues about the atmosphere’s dynamics and interaction with the surface. It captures sunlight streaming through the atmosphere.

“The hazes detected in this image are a key element in creating the complex hydrocarbon compounds that give Pluto’s surface its reddish hue.”

Methane (CH4) in the upper atmosphere break down by interaction of UV radiation and forms ethylene and acetylene which leads to more complex hydrocarbons known as tholins – which the team says is responsible for Pluto’s remarkable reddish hue.

The team also released new LORRI images showing “extensive evidence of exotic ices flowing across Pluto’s surface and revealing signs of recent geologic activity, something scientists hoped to find but didn’t expect.”

The images focuses on Sputnik Planum, a Texas-sized plain, which lies on the western, left half of Pluto’s bilobed and bright heart-shaped feature, known as Tombaugh Regio.

New imagery and spectral evidence from the Ralph instrument was presented that appears to show the flow of nitrogen ices in geologically recent times across a vast region. They appear to flow similar to glaciers on Earth. There are also carbon monoxide and methane ices mixed in with the water ices.

“We’ve only seen surfaces like this on active worlds like Earth and Mars,” said mission co-investigator John Spencer of SwRI. “I’m really smiling.”

“In the southernmost region of the heart, adjacent to the dark equatorial region, it appears that ancient, heavily-cratered terrain has been invaded by much newer icy deposits.”

“We see the flow of viscous ice that looks like glacial flow.”

If the spacecraft remains healthy as expected, the science team plans to target New Horizons to fly by another smaller Kuiper Belt Object (KBO) as soon as 2018.

Pluto’s Heart of the Heart Swathed in Newly Discovered Icy Mountains and Vast Plains

APPLIED PHYSICS LABORATORY, LAUREL, MD – The highest resolution images ever taken of Pluto by humanity’s first spacecraft ever to visit the last planet in our solar system revealed unanticipated new discoveries of ice mountains as tall as the Rockies and vast craterless plains spanning hundreds of miles (kilometers) across – are now shown in our newly created context mosaic (featured above and below) of the heart-shaped ‘Tombaugh Regio’ area that dominates the alien planet’s surface.

These stunning and astoundingly young features only now unveiled on Pluto’s surface were created in very recent times, geologically speaking said top scientists leading NASA’s resounding successful New Horizons mission, at a media briefing on July 17.

This first high resolution surface mosaic was created from a newly unveiled series of black and white images centered in the Heart of Pluto’s huge ‘Heart, including the ice mountains of ‘Sputnik Planum’ and icy plains of ‘Norgay Montes.’

They were captured by New Horizons’ high resolution Long Range Reconnaissance Imager (LORRI) on July 14 as the probe barreled past the Pluto-Charon binary planet system only four days ago on Tuesday, July 14, at over 31,000 mph (49,600 kph).

These highest resolution LORRI images focused on the “Heart of the Heart” of Pluto have now been stitched into a mosaic by the image processing team of Marco Di Lorenzo and Ken Kremer.

Pluto’s bright heart-shaped region has now been informally renamed “Tombaugh Regio,’ announced John Spencer, New Horizons science team co-investigator at the post flyby media briefing on July 15.

The mosaic of Pluto’s ‘Tombaugh Regio’ is based on the initial imagery released so far as of July 17.

This annotated view of a portion of Pluto’s Sputnik Planum (Sputnik Plain), named for Earth’s first artificial satellite, shows an array of enigmatic features. The surface appears to be divided into irregularly shaped segments that are ringed by narrow troughs, some of which contain darker materials. Features that appear to be groups of mounds and fields of small pits are also visible. This image was acquired by the Long Range Reconnaissance Imager (LORRI) on July 14 from a distance of 48,000 miles (77,000 kilometers). Features as small as a half-mile (1 kilometer) across are visible. Credits: NASA/JHUAPL/SWRI

A pair of high resolution LORRI images was aimed at areas now informally named Norgay Montes (Norgay Mountains) and Sputnik Planum (Sputnik Plain).

Norgay Montes is informally named for Tenzing Norgay, one of the first two humans to reach the summit of Mount Everest, along with Sir Edmund Hillary. Sputnik Planum is informally named for Earth’s first artificial satellite launched by the Soviet Union in 1957.

The two LORRI images are draped over a wider, lower resolution view of Tombaugh Regio – in annotated and unannotated versions. This is highest resolution currently available.

To the left of the mosaic are two small inserts showing possible “wind streaks” say the researchers.

To the right of the mosaic is a global view of Pluto showing the location of Tombaugh Regio and also outlined to show the precise location of the high resolution LORRI mosaic.

The frozen region of Norgay Montes is situated north of Pluto’s icy mountain range at Sputnik Planum.

“This terrain is not easy to explain,” said Jeff Moore, leader of the New Horizons Geology, Geophysics and Imaging Team (GGI) at NASA’s Ames Research Center in Moffett Field, California.

“The discovery of vast, craterless, very young plains on Pluto exceeds all pre-flyby expectations.”

“The landscape is astoundingly amazing. There are a few ancient impact craters on Pluto. But other areas like “Tombaugh Regio” show no craters. The landform change processes are occurring into current geologic times.”

“There are no impact craters in a frozen area north of Pluto’s icy mountains we are now informally calling ‘Sputnik Planum’ after Earth’s first artificial satellite.”

New close-up images of a region near Pluto’s equator reveal a giant surprise -- a range of youthful mountains rising as high as 11,000 feet (3,500 meters) above the surface of the icy body.

‘Sputnik Planum’ is composed of a broken surface of irregularly-shaped segments. The polygonal shaped areas are roughly 12 miles (20 kilometers) across, bordered by what appear to be shallow troughs based on a quick look at the data.

The mountain ranges height rival those of the Rockies, says Moore.

The new LORRI close-ups show the icy mountain range has peaks jutting as high as 11,000 feet (3,500 meters) above the surface, announced John Spencer, New Horizons science team co-investigator at the media briefing.

“It’s a very young surface, probably formed less than 100 million years old,’ said Spencer. “It may be active now.”

“Judging from the absence of impact craters, it’s clear that Sputnik Planum couldn’t possibly be more than 100 million years old, and possibly is still being shaped to this day by geologic processes,” noted Moore. “This could be only a week old for all we know.”

During the fast flyby encounter, the New Horizons spacecraft pointed its suite of seven science instruments exclusively on all the bodies in the Pluto system, to maximize the capture of scientific data, as quickly as possible, and store it onto its two solid state digital recorders for later playback.

A major challenge for the mission is the rather slow “downlink” transmission of data back to Mission Control on Earth. Since the average “downlink” is only about 2 kilobits per second via its two transmitters, it will take about 16 months to send all the flyby data back to Earth.

Therefore the team has carefully selected just a few of the highest resolution images and other key instrument data for quick playback. The remaining flyby data will be prioritized for streaming.

“Over 50 gigabits of data were collected during the encounter and flyby periods,” New Horizons principal investigator Alan Stern of the Southwest Research Institute, Boulder, Colorado, said during the July 17 media briefing.

“So far less than 1 gigabit of data has been returned.”

New Horizons 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.

If the spacecraft remains healthy as expected, the science team plans to target New Horizons to fly by another smaller Kuiper Belt Object (KBO) as soon as 2018.
