The New Horizons probe will be slowly downloading images and data from its July flyby of Pluto over the next year. Yesterday the mission released the highest resolutions images yet obtained of the surface of Pluto.
NASA’s New Horizons spacecraft has sent back the first few of a series of the sharpest views of Pluto it obtained during its July flyby – and this image sequence forms the best close-ups of Pluto that humans may see for decades.
Every week the piano-sized New Horizons spacecraft transmits data stored on its digital recorders from its flight through the Pluto system on July 14. These latest pictures are part of a sequence taken near New Horizons’ closest approach to Pluto, with resolutions of about 250-280 feet (77-85 meters) per pixel – revealing features less than half the size of a city block on the diverse surface of the distant planet. In these new images, New Horizons captured a wide variety of spectacular, cratered, mountainous and glacial terrains.
The Mountainous Shoreline of Sputnik Planum: Great blocks of Pluto’s water-ice crust appear jammed together in the informally named al-Idrisi mountains. Some mountain sides appear coated in dark material, while other sides are bright.

The images being released today form a strip 50 miles (80 kilometers) wide trending from Pluto’s jagged horizon about 500 miles (800 kilometers) northwest of the informally named Sputnik Planum, across the al-Idrisi mountains, onto the shoreline of Sputnik and then across its icy plains.
Layered Craters and Icy Plains: Pluto’s rugged, icy cratered plains include layering in the interior walls of many craters. Layers in geology usually mean an important change in composition or event, but at the moment New Horizons team members do not know if they are seeing local, regional or global layering.

The science we can do with these images is simply unbelievable.”
A video made from these images reveals amazing details on a world 3 billion miles away – as do individual close-ups taken from the wider swath. The images are six times better than the resolution of the global Pluto map New Horizons obtained, and five times better than the best images of Pluto’s cousin Triton, Neptune’s large moon, obtained by Voyager 2 in 1989.
Very Best Views of Pluto: This movie is composed of the sharpest views of Pluto that NASA’s New Horizons spacecraft obtained during its flyby of the distant planet on July 14, 2015. The pictures are part of a sequence taken near New Horizons’ closest approach to Pluto, with resolutions of about 250-280 feet (77-85 meters) per pixel – revealing features smaller than half a city block on Pluto’s diverse surface. The images include a wide variety of spectacular, cratered, mountainous and glacial terrains – giving scientists and the public alike a breathtaking, super-high resolution window on Pluto’s geology.

“The mountains bordering Sputnik Planum are absolutely stunning at this resolution” added New Horizons science team member John Spencer. “The new details revealed here, particularly the crumpled ridges in the rubbly material surrounding several of the mountains, reinforce our earlier impression that the mountains are huge ice blocks that have been jostled and tumbled and somehow transported to their present locations.”
These images were made with the telescopic Long Range Reconnaissance Imager (LORRI) aboard New Horizons, in a timespan of about a minute centered on 11:36 UT on July 14 – just about 15 minutes before New Horizons’ closest approach to Pluto – from a range of just 10,000 miles (17,000 kilometers). They were obtained with an unusual observing mode; instead of working in the usual “point and shoot,” LORRI snapped pictures every three seconds while the Ralph/Multispectral Visual Imaging Camera (MVIC) aboard New Horizons was scanning the surface. This mode requires unusually short exposures to avoid blurring the images.
Pluto’s Badlands: Erosion and faulting has sculpted portions of Pluto’s icy crust into rugged badlands. The prominent 1.2-mile-high cliff at the top, running from left to upper right, is part of a great canyon system that stretches for hundreds of miles across Pluto’s northern hemisphere.

New Horizons, speeding through deep space at more than 32,000 miles per hour, is approximately 104 million miles (167 million kilometers) beyond Pluto and 3.2 billion miles (5.2 billion kilometers) from Earth. All spacecraft systems are healthy.
New Horizons is part of NASA’s New Frontiers Program, managed by the agency’s Marshall Space Flight Center in Huntsville, Alabama. The Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, designed, built, and operates the New Horizons spacecraft and manages the mission for NASA’s Science Mission Directorate. The Southwest Research Institute leads the mission and mission science, payload operations, and encounter science planning.
The Canadian company UrtheCast has high definition earth-observation cameras mounted on the exterior of the Int. Space Station and it has a set of earth-obs satellites.
Monitoring the world’s forests requires looking at things both large and small. With forests covering a vast 30 percent of the Earth’s land surface, large-scale public satellite programs help scan forests rapidly at medium and coarse resolutions. But to really understand how a forest is changing, or identify the drivers of deforestation, you need ultra-high-resolution satellite images that show the finer details. Forest managers have traditionally lacked the latter — less than a decade ago, even a moderate-resolution image could have cost thousands of dollars, rendering this powerful resource too expensive for conservation efforts.
That all changed when NASA and USGS released their Landsat archives for free, and the game may be about to change again. Companies are now pioneering ways to also bring high-resolution images to scientists and the public at little or no cost to analyze them for critical information about forests around the world.
UrtheCast is the latest company to lend its immense Earth Observation capacity to the cause, in partnership with Global Forest Watch (GFW) — a dynamic online platform that allows anyone, anywhere with an internet connection to monitor the loss of trees around the world. Soon, Global Forest Watch will roll out a feature that allows users free access to UrtheCast images, ranging in resolution from 20m to as high as 70cm in resolution, all sortable by filter, maximum cloud cover percentage, and date range.
GFW users will also be able to subscribe to email updates and can be notified as new images for their areas of interest are acquired. Care about fires in Indonesia or the spread of illegal logging in Peru? You’ll be able to track these changes not only using GFW’s data sets and alert systems, but see them with your own eyes.
Today, many forest stakeholders rely on remote sensing technologies powered by satellite imagery to make better informed decisions around forest management and conservation. Thanks to companies like UrtheCast, access to high-quality images continues to increase, as does our ability to monitor global forest change and put information into the hands of more stakeholders around the world.
