Wright Mons in colour. This composite image of a possible ice volcano on Pluto includes pictures taken by the New Horizons spacecraft’s Long Range Reconnaissance Imager (LORRI) on 14 July 2015, from a range of about 30,000 miles (48,000 kilometres), showing features as small as 1,500 feet (450 metres) across. Sprinkled across the LORRI mosaic is enhanced colour data from the Ralph/Multispectral Visible Imaging Camera (MVIC), from a range of 21,000 miles (34,000 kilometres) and at a resolution of about 2,100 feet (650 metres) per pixel. The entire scene is 140 miles (230 kilometres) across.

This feature, known as Wright Mons, was informally named by the New Horizons team in honour of the Wright brothers. At about 90 miles (150 kilometres) across and 2.5 miles (4 kilometres) high, this feature is enormous. If it is in fact a volcano, as suspected, it would be the largest such feature discovered in the outer solar system.
Mission scientists are intrigued by the sparse distribution of red material in the image and wonder why it is not more widespread. Also perplexing is that there is only one identified impact crater on Wright Mons itself, telling scientists that the surface (as well as some of the crust underneath) was created relatively recently. This is turn may indicate that Wright Mons was volcanically active late in Pluto’s history.Image credits: NASA/JHUAPL/SwRI.
The first images from the New Horizons spacecraft since late July will come back to Earth on 5 September, and scientists are salivating over what the new pictures will reveal about Pluto.
In June 2015, when the cameras on NASA’s approaching New Horizons spacecraft first spotted the large reddish polar region on Pluto’s largest moon, Charon, mission scientists knew two things: they’d never seen anything like it elsewhere in our Solar System, and they couldn’t wait to get the story behind it.
The New Horizons team described a wide range of findings about the Pluto system in its first research paper published today — just three months after NASA’s historic first exploration of the dwarf planet. New Horizons has revealed a degree of diversity and complexity on Pluto and its moons that few expected in the frigid outer reaches of the solar system.
