I couldn’t believe the beauty and the details that were awaiting us at Pluto. We would have never expected the unusual terrain we’ve seen. We saw a heart-shaped glacier made out of nitrogen and carbon monoxide ices. At the edge of the glacier there were huge mountains—mountains as tall as the Rocky Mountains—made out of water ice. Pluto has a large moon named Charon, and on that moon there’s a deep canyon, deeper than the Grand Canyon. All these wonders awaited us.
