This Pluto mosaic was made from New Horizons LORRI images taken on July 14, 2015, from a distance of 49,700 miles (80,000 km). This view is projected from a point 1,118 miles (1,800 km) above Pluto’s equator, looking northeast over the dark, cratered Cthulhu Regio toward the bright, smooth expanse of icy plains called Sputnik Planum. Pluto’s North Pole is off the image to the left. This mosaic was produced with panchromatic images from the New Horizons LORRI camera, with color overlaid from the Ralph color mapper onboard New Horizons. Image credit: S.A. Stern et al.

This mosaic of Cerealia Facula is based on images obtained by NASA’s Dawn spacecraft in its second extended mission, from an altitude as low as about 21 miles (34 km). The contrast in resolution obtained by the two phases is visible here, reflected by a few gaps in the high-resolution coverage. This image is superposed to a similar scene acquired in the low-altitude mapping orbit of the mission from an altitude of about 240 miles (385 km). The increased resolution afforded by the low altitude is revealing intimate details about the relationships between bright and dark materials across the facula, which will help resolve the mystery of its origin. Cerealia Facula is located at about 19.7 degrees north latitude and 239.6 degrees east longitude. Image credit: NASA / JPL-Caltech / UCLA / MPS / DLR / IDA / PSI.

This high-resolution image of Pluto was taken by New Horizons on July 14. Pluto’s surface sports a remarkable range of subtle colors, enhanced in this view to a rainbow of pale blues, yellows, oranges, and deep reds. Many landforms have their own distinct colors, telling a complex geological and climatological story that scientists have only just begun to decode.

According to Zhang et al, Pluto’s atmosphere is unique among Solar System planetary atmospheres, as its equilibrium temperature is controlled primarily by solid-phase haze particles instead of gas molecules. This artist’s impression shows a view of the moon Charon through Pluto’s atmospheric haze layers above the mountain landscape of bedrock water ice covered partially with deposition of dark, reddish haze particles.
