The first global maps of Pluto and its moon Charon are now available, putting a bookend to NASA's New Horizons mission
"From a finalist's point of view, these are all good data we have, badembled in a Ross Beyer, NASA Ames Research Center at Moffett Field, Calif.
The graphs focus on the 42% of Pluto and 45% of Charon where New Horizons took images of at least two angles during its 2015 flyover, revealing the height and depth of landscapes ( SN: 27/06/15, p.16 )
These measures add Topographic details with already known features: For example, the gentle plains of Pluto's particular ice sheet, known as Sputnik Planitia, lie between two and three kilometers under the circumference of the area.
Largest surprise of Pluto is a system of crests of 3 200 kilometers, troughs that trace a single long line across the dwarf planet. Beyer and his colleagues report online on June 11 in Icarus . This feature was only visible with all the data collected, explains Beyer. L & # 39; n & # 39 team; not a good explanation for its formation still

The map of Charon confirms that the moon is made up of two large areas: plain plains of 39; southern hemisphere and fractured blocks and canyons north, Beyer and colleagues report online July 3 in another article in Icarus ( SN: 4/2/16, p.20 At the beginning, the scientists thought the two fields were at the same elevation, but the new map shows that the plains are one kilometer or two lower than the northern terrain.
"We do not know exactly why it's still, but it's certainly interesting, "says Beyer.Other planetary scientists will use these maps to continue unearthing the secrets of Pluto and Charon:" These maps actually form the base, the cartographic base, of all that any other scientist will do ", says Beyer. e, v, n, t, s) {if (f.fbq) returns; n = f.fbq = function () {n.callMethod?
