New Pluto images reveal a crazy variety of surface features!
New Horizons began its yearlong download of new images and other data over the weekend. Close-up images downlinked in the past few days have more than doubled the amount
of Pluto’s surface seen at resolutions as good as 400 meters (440
yards) per pixel. They reveal new features as diverse as possible dunes,
nitrogen ice flows, and even networks of valleys that may have been carved by
material flowing over Pluto’s surface. They also show large regions that
display chaotically jumbled mountains.
