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.
NASA’s New Horizons space probe, 10 days from a one-shot encounter with enigmatic Pluto, stopped collecting science data Saturday after a technical problem interrupted the spacecraft’s tightly-choreographed flight plan.
Clyde Tombaugh discovered Pluto over 85 years ago. He died in 1997, but during the historic 14 July flyby of NASA’s New Horizons spacecraft, Clyde’s children Alden and Annette Tombaugh will be special guests at mission headquarters. Here they reflect on their father’s legacy.
At half the diameter of Pluto, Charon is the largest satellite relative to its planet in the solar system. NASA’s New Horizons spacecraft has returned the best colour and the highest resolution images yet of Charon, showing a landscape covered with mountains, canyons, landslides, surface-colour variations and more — all evidence of a surprisingly complex and violent history.
