The next destination for the New Horizons mission to visit after its historic July 14 flyby of the Pluto system is likely a small Kuiper Belt object (KBO) known as 2014 MU69 that orbits nearly a billion miles beyond Pluto.

The team needs to direct New Horizons toward the object this year in order to perform any extended mission with healthy fuel margins...

In the northern region of Pluto’s Sputnik Planum, 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. Credits: NASA/JHUAPL/SwRI

NASA’s New Horizons mission has found evidence of exotic ices flowing across Pluto’s surface, at the left edge of its bright heart-shaped area. New close-up images from the spacecraft’s Long-Range Reconnaissance Imager (LORRI) reveal signs of recent geologic activity, something scientists hoped to find but didn’t expect. “We’ve only seen surfaces like this on active worlds like Earth and Mars,” said mission co-investigator John Spencer of SwRI.

The new close-up images show fascinating detail within the Texas-sized plain (Sputnik Planum) ...

A new close-up image of Pluto reveals a vast, craterless plain that appears to be no more than 100M yrs old, and is possibly still being shaped by geologic processes. This frozen region is 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 fascinating icy plains region – resembling frozen mud cracks on Earth — has been informally named “Sputnik Planum” (Sputnik Plain) after the Earth’s first artificial satellite. It has a broken surface of irregularly-shaped segments, roughly 12 miles across, bordered by what appear to be shallow troughs...

IMAGE1: The latest spectra from New Horizons Ralph instrument reveal abundance of methane ice, but with striking differences from place to place across the frozen surface of Pluto. “We just learned that in the north polar cap, methane ice is diluted in a thick, transparent slab of nitrogen ice resulting in strong absorption of infrared light,” …In one of the visually dark equatorial patches, the methane ice has shallower infrared absorptions indicative of a different texture. “The spectrum appears as if the ice is less diluted in N…or that it has a different texture in that area.”

IMAGE2: 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 above the surface of the icy body...
