This 3-D image of Pluto, which requires red/blue stereo glasses for viewing (click the picture for a full-screen version), shows a region 180 miles (300 kilometres) across, centred near longitude 130°E, latitude 20°N (the red square in the global context image). North is to the upper left. The image shows an ancient, heavily cratered region of Pluto, dotted with low hills and cut by deep fractures indicating extension of Pluto’s crust. Image credit: NASA/JHUAPL/SwRI.Global stereo mapping of Pluto’s surface is now possible, as images taken from multiple directions are downlinked from NASA’s New Horizons spacecraft. Stereo images will eventually provide an accurate topographic map of most of the hemisphere of Pluto seen by New Horizons during the 14 July flyby, which will be key to understanding Pluto’s geological history.
This example, which requires red/blue stereo glasses for viewing, shows a region 180 miles (300 kilometres) across, centered near longitude 130°E, latitude 20°N (the red square in the global context image). North is to the upper left. The image shows an ancient, heavily cratered region of Pluto, dotted with low hills and cut by deep fractures indicating extension of Pluto’s crust.
Analysis of these stereo images shows that the steep fracture in the upper left of the image is about 1 mile (1.6 kilometres) deep, and the craters in the lower right part of the image are up to 1.3 miles (2.1 kilometres) deep. Smallest visible details are about 0.4 miles (0.6 kilometres) across.
It seems that the more we see of Pluto, the more fascinating it gets. This latest image, from the heart of Pluto’s heart feature, shows the plains’ enigmatic cellular pattern as well as unusual clusters of small pits and troughs. Adding to the intrigue is that even at this resolution of 250 metres, no impact craters are seen, testifying to the region’s extreme geologic youth.
Two of Pluto’s mini-moons, the mysterious Nix and Hydra, have transitioned from featureless points of light into their own worlds with new imagery from NASA’s New Horizons spacecraft.
Geologists said Thursday they are bewildered by images from NASA’s New Horizons spacecraft baring unseen landscapes on Pluto with unexpected “snakeskin” textures, colourful chasms routing through ancient landforms, and vivid new views of apparent glacial flows.
