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.
From possible ice volcanoes to twirling moons, NASA’s New Horizons science team is discussing more than 50 exciting discoveries about Pluto at this week’s 47th Annual Meeting of the American Astronomical Society’s Division for Planetary Sciences. The two cryovolcano candidates are large features measuring tens of miles across and several miles high.
“X” marks the spot of some intriguing surface activity in the latest picture of Pluto returned from NASA’s New Horizons spacecraft. This image from the Long Range Reconnaissance Imager (LORRI) extends New Horizons’ highest-resolution views of Pluto to the very centre of Sputnik Planum, the informally named icy plain that forms the left side of Pluto’s “heart” feature.
A long-awaited radio signal from NASA’s New Horizons spacecraft landed on planet Earth late Tuesday, confirming the faraway space probe performed as expected during a one-shot flyby of Pluto at the solar system’s outer frontier.
