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 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.

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.”

‘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.

A vast, hundreds of miles wide craterless plain of Plutonian ice no more than 100 million years old and centered amidst Pluto’s big ‘heart’ was unveiled in spectacular new imagery taken by NASA’s resounding successful New Horizons mission, during its history making rapid transit through the Pluto-Charon binary planet system barely three days ago, on Tuesday, July 14.

The jaw dropping new imagery of young plains of water ice was publicly released today, July 17, by NASA and scientists leading the New Horizons mission during a media briefing, and has already resulted in ground breaking new scientific discoveries at the last planet in our solar system to be visited by a spacecraft from Earth.

“We have now visited every planet in our solar system with American spacecraft,” said NASA Administrator Charles Bolden. “These findings are already causing us to rethink the dynamics of interior geologic processes.”

New data and dazzling imagery are now from streaming back some 3 billion miles across interplanetary space to mission control on Earth and researchers eagerly awaiting the fruits of more than two decades of hard labor to get to this once-in-a-lifetime opportunity.

“I can’t wait for the new discoveries!” exclaimed Bolden at today’s media briefing.

“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 media briefing.

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

It will take some 16 months for all the Pluto flyby data to be transmitted back to Earth.

And the team has not been disappointed because the results so far shows Pluto to possess tremendously varied terrain that “far exceed our expectations.”

Two new high resolution images captured by the probes Long Range Reconnaissance Imager (LORRI) on July 14 were released today and taken from a distance of 48,000 miles (77,000 kilometers). Features as small as one-half mile (1 kilometer) across are visible in the images – shown above and below.

They were snapped from frozen region lying north of Pluto’s icy mountains, in the center-left of the heart feature, informally named “Tombaugh Regio” (Tombaugh Region) after Clyde Tombaugh, who discovered Pluto in 1930.

“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 astounding. 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.”

‘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.

Notably, some of the clumps are filled with mysterious darker material. Hills are also visible in some areas, which may have been pushed up. Etched areas on the surface may have been formed by sublimation process where the water ice turns directly from the solid to the gas phase due to the extremely negligible atmosphere pressure.

In some places there are also streaks that may have formed from windblown processes and pitted areas.

“It’s just pure coincidence that we got the highest resolution data at Sputnik Planum which is of the most interest scientifically,” Moore noted.

Moore indicated that the team is working on a pair of theories as to how these polygonal segments were formed.

“The irregular shapes may be the result of the contraction of surface materials, similar to what happens when mud dries. Alternatively, they may be a product of convection, similar to wax rising in a lava lamp. On Pluto, convection would occur within a surface layer of frozen carbon monoxide, methane and nitrogen, driven by the scant warmth of Pluto’s interior,” Moore explained.

Pluto’s polygons look remarkably similar to the Martian polygons upon which NASA’s Phoenix lander touched down on in 2008 and dug into. Perhaps they were formed by similar mechanisms or difference ones, contraction or convection, Moore told me during the briefing.

As of yesterday, New Horizons spacecraft completed and exited the Pluto encounter phase, said Stern. “We are now collecting departure science.”

New Horizons is already over 3 million miles beyond Pluto and heading to its next yet to be determined target in the Kuiper Belt.

“With the flyby in the rearview mirror, a decade-long journey to Pluto is over –but, the science payoff is only beginning,” said Jim Green, director of Planetary Science at NASA Headquarters in Washington.

“Data from New Horizons will continue to fuel discovery for years to come.”

APPLIED PHYSICS LABORATORY, LAUREL, MD – Scientists leading NASA’s historic New Horizons mission to the Pluto system announced the first of what is certain to be a tidal wave of new discoveries, including the totally unexpected finding of young ice mountains at Pluto and crispy clear views of young fractures on its largest moon Charon, at a NASA media briefing today (July 15) at the Applied Physics Laboratory (APL) in Laurel, Maryland.

A treasure trove of long awaited data has begun streaming back to Mission Control at Johns Hopkins University Applied Physics Laboratory to the mouth watering delight of researchers and NASA.

With the first ever flyby of Pluto, America completed the initial up close reconnaissance of the planets in our solar system. Pluto was the last unexplored planet, building on missions that exactly started 50 years ago in 1965 when Mariner IV flew past Mars.

“Pluto New Horizons is a true mission of exploration showing us why basic scientific research is so important,” said John Grunsfeld, associate administrator for NASA’s Science Mission Directorate in Washington.

“The mission has had nine years to build expectations about what we would see during closest approach to Pluto and Charon. Today, we get the first sampling of the scientific treasure collected during those critical moments, and I can tell you it dramatically surpasses those high expectations.”

Today the team announced that New Horizons has already made a totally unexpected discovery showing clear evidence of ice mountains on Pluto’s surface in the bright area informally known as the ‘big heart of Pluto.’

The new close-up image released today showed an icy mountain range near the base of the heart with 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.”

Spencer also announce that the heart shaped region will now be named “Tombaugh Reggio” in honor of Clyde Tombaugh, the American astronomer who discovered Pluto in 1930.

“We are seeing water ice.”

“I never would have imagined this!” Spencer exclaimed.

“And I’m very surprised that there are no craters in the first high resolution images.”

The finding of ice mountains has major scientific implications.

Unlike the icy moons of giant planets, Pluto cannot be heated by gravitational interactions with a much larger planetary body. Some other process must be generating the mountainous landscape, said the team.

“This may cause us to rethink what powers geological activity on many other icy worlds,” says Spencer of SwRI.

“Pluto may have internal activity. There may be geysers or cryovolcanoes,” New Horizons principal investigator Alan Stern of the Southwest Research Institute, Boulder, Colorado, said during the media briefing. However there is no evidence for them yet.

Additional high resolution images for “Tombaugh Reggio” area are being transmitted back to Earth today and will continue.

“Finding a mountain range of ice is a complete surprise,” Stern noted.

After a nine year voyage through interplanetary space, New Horizons barreled past the Pluto system on Tuesday, July 14 for a history making first ever flyby at over 31,000 mph (49,600 kph), and survived the passage by swooping barely 7,750 miles (12,500 kilometers) above the planet’s amazingly diverse surface.

The team had to wait another 12 hours for confirmation that the spacecraft lived through the daring encounter when signals were reacquired as planned at 8:53 p.m. EDT last night. Since New Horizons swung past Pluto to continue its voyage, the probe is now more than million miles outbound just 24 hours later.

NASA’s New Horizons Zooms By Pluto, Solar Systems Last Planet – King of The Kuiper Belt

APPLIED PHYSICS LABORATORY, LAUREL, MD – With this morning’s (July 14) do or die flyby of Pluto by NASA’s New Horizons spacecraft at 7:49 a.m. EDT while traveling over 3 billion miles away, America completed the initial up close reconnaissance of the last explored planet of our solar system at its frigid, far flung reaches and revealed a remarkably differentiated world dazzling us with alien terrain far beyond anyone’s expectation.

New Horizons barreled past Pluto for a history making first ever flyby at over 31,000 mph (49,600 kph) and passed only 7,750 miles (12,500 kilometers) above the planet’s amazingly diverse surface.

To mark the occasion, NASA released the highest resolution image ever taken of Pluto as the probe swooped past its prey this morning, centered on the two lobed, differentiated ‘heart’.

But because the one ton piano shaped spacecraft has been out of touch with Mission Control for the past day as planned and busily gathering hordes of priceless data, confirmation of a successful flyby didn’t reach Mission Control on Earth until half a day later when New Horizons ‘phoned home’ with critical engineering data confirmed the health of the probe at 8:53 p.m. EDT this evening- basically saying “I’m Alive”.

“With this mission we have we have visited every planet in our solar system,” proclaimed NASA Administrator Charles Bolden this evening, July 14, to a packed house of cheering team members, invited guests and media including Universe Today at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Maryland, during a live NASA TV media briefing shortly after accomplishing the historic feat after the nine year interplanetary voyage.

“No other nation has that capability. It’s a historic day for exploration.”

“We did it! exclaimed New Horizons principal investigator Alan Stern of the Southwest Research Institute, Boulder, Colorado, during the live media briefing.

“That’s one small step for New Horizons, one giant leap for mankind,” Stern added, paraphrasing humanity’s first moonwalker, Neil Armstrong.

“New Horizons completes the first planetary reconnaissance, a capstone of our time.”

The Pluto flyby took place on the 50th anniversary of the first interplanetary flyby by America’s Mariner 4 spacecraft when it soared past Mars in 1965.

“Today we inspired a whole generation of new explorers,” Bolden said to the crowd emotionally. “And you have more to do!” – as he pointedly acknowledge a crowd of young people in the room.

Pluto is covered by a spectacular array of craters, mountains, valleys, a whale shaped dark feature and a huge heart-shaped continent of pinkinsh bright ice as seen in the image taken on July 13 when the spacecraft was 476,000 miles (768,000 kilometers) from the surface.

“New Horizons has sent back the most detailed data ever of Pluto and its system of moons.”

“Every mission expands our horizons and bring us one step further on the Journey to Mars,” said Bolden regarding NASA’s agency wide plans to send astronauts to the Red Planet during the 2030s.

“You have made Pluto almost human.”

Tomorrow, the more than year long data playback begins.

“The best is yet to come,” said John Grunsfeld, NASA Associate Administrator for the Science Mission Directorate, at the media briefing.

“You haven’t seen anything yet. There are many more months of data to be sent back.”

“This is like the Curiosity landing. This is just the beginning for fundamental discoveries. It’s a tremendous moment in human history.”

Congratulations rolled in from around the world including President Obama and world renowned physicist Stephen Hawking.

It has been three decades since we last visited planetary bodies at the outer reaches of our solar system when Voyager 2 flew past Uranus and Neptune in 1986 and 1989.

The New Frontiers spacecraft was built by a team led by Stern and included researchers from SwRI and the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Maryland. APL also operates the New Horizons spacecraft and manages the mission.

Naming Pluto: Christening Features on Brave New Worlds

‘Here be Dragons…’ read the inscriptions of old maps used by early seafaring explorers. Such maps were crude, and often wildly inaccurate.

The same could be said for our very understanding of distant planetary surfaces today. But this week, we’ll be filling in one of those ‘terra incognita’ labels, as New Horizons conducts humanity’s very first reconnaissance of Pluto and its moons.

The closest approach for New Horizons is set for Tuesday, July 14th at 11:49 UT/7:49 AM EDT, as the intrepid spacecraft passes 12,600 kilometres (7,800 miles) from Pluto’s surface. At over 4 light hours or nearly 32 astronomical units (AUs) away, New Horizons is on its own, and must perform its complex pirouette through the Pluto system as it cruises by at over 14 kilometres (8 miles) a second.

This also means that we’ll be hearing relatively little from the spacecraft on flyby day, as it can’t waste precious time pointing its main dish back at the Earth. With a downlink rate of 2 kilobits a second—think ye ole 1990’s dial-up, plus frozen molasses—it’ll take months to finish off data retrieval post flyby. A great place to watch a simulation of the flyby ‘live’ is JPL’s Eyes on the Solar System, along with who is talking to New Horizons currently on the Deep Space Network with DSN Now.

Launched in 2006, New Horizons is about to join the ranks of nuclear-fueled explorers that have conducted first time reconnaissance of solar system objects.

Bob King also wrote up an excellent timeline of New Horizons events for Universe Today yesterday. Also be sure to check out the Planetary Society’s in-depth look at what to expect by Emily Lakdawalla.

Seems strange that after more than a decade of recycling the same blurry images and artist’s conceptions in articles, we’re now getting a new and improved shot of Pluto and Charon daily!

To follow the tale of Pluto is to know the story of modern planetary astronomy. Discovered in 1930 by American astronomer Clyde Tombaugh from the Lowell Observatory, Pluto was named by 11-year old Venetia Burney. Venetia just passed away in 2009, and there’s a great short documentary interview with her entitled Naming Pluto.

Fun fact: Historians at the Carnegie Institute recently found images of Pluto on glass plates… dated 1925, from five years before its discovery.

Despite the pop culture reference, Pluto was not named after the Disney dog, but after the Roman god of the underworld. Pluto the dog was not named in Disney features until late 1930, and if anything, the character was more than likely named after the buzz surrounding the newest planet on the block.

We’re already seeing features on Pluto and Charon in the latest images, such as the ‘heart,’ ‘donut,’ and the ‘whale’ of Pluto, along with chasms, craters and a dark patch on Charon. The conspicuous lack of large craters on Pluto suggests an active world.

The International Astronomical Union (IAU) convention for naming any new moons discovered in the Plutonian system specifies characters related to the Roman god Pluto and tales of the underworld.

With features, however, cartographers of Pluto should get a bit more flexibility. Earlier this year, the Our Pluto campaign invited the public to cast votes to name features on Pluto and Charon related to famous scientists, explorers and more. The themes of ‘fictional explorers and vessels’ has, of course, garnered much public interest, and Star Trek’s Mr. Spock and the Firefly vessel Serenity may yet be memorialized on Charon. Certainly, it would be a fitting tribute to the late Leonard Nimoy. We’d like to see Clyde Tombaugh and Venetia Burney paid homage to on Pluto as well.

We’ve even proposed the discovery of a new moon be named after the mythological underworld character Alecto, complete with a Greek ‘ct’ spelling to honor Clyde Tombaugh.

The discovery and naming of Charon in 1978 by astronomer Robert Christy set a similar precedent. Christy choose the name of the mythological boatman who plied the river Styx (which also later became a Plutonian moon) as it included his wife Charlene’s nickname ‘Char.’ This shibboleth  also set up a minor modern controversy as to the exact pronunciation of Charon, as the mythological character is pronounced with a hard ‘k’ sound, but most folks (including NASA) say the moon as ‘Sharon’ in keeping with Christy’s in-joke that slipped past the IAU.

And speaking of Pluto’s large moon, someone did rise to the occasion and take our ‘Charon challenge,’ we posed during the ongoing Pluto opposition season recently. Check out this amazing capture of the +17th magnitude moon winking in and out of view next to Pluto courtesy of Wendy Clark:

Clark used the 17” iTelescope astrograph located at Siding Spring Observatory in Australia to tease out the possible capture of the itinerant moon.

Great job!

What’s in a name? What strange and wonderful discoveries await New Horizons this week? We should get our very first signal back tomorrow night, as New Horizons ‘phones home’ with its message that it survived the journey around 9:10 PM EDT/1:10 UT. Expect this following Wednesday—in the words of New Horizons principal Investigator Alan Stern—to begin “raining data,” as the phase of interpreting and evaluating information begins.

And there’s more in store, as the New Horizons team will make the decision to maneuver the spacecraft for a rendezvous with a Kuiper Belt Object (KBO) next month. Said KBO flyby will occur in the 2019-2020 timeframe, and perhaps, we’ll one day see a Pluto orbiter mission or lander in the decades to come…

Maybe one way journeys to ‘the other Red Planet’ are the wave of the future.’ Pluto One anyone?
