Hi, I’m Carly Howett, a senior research scientist at the Southwest Research Institute in Boulder, Colorado. I’ve been working on NASA’s New Horizons mission since 2012, focusing on an instrument named Ralph, which among other things provides the color “eyes” for the spacecraft. When I started looking at Ralph images of Pluto and its largest moon, Charon, back in 2012, the bodies were so far away they appeared as just a speck of light, too close together to see separately. So you can imagine how excited I was to see Pluto and Charon not only as separate worlds this year, but with clear and different features across them. It is these differences, specifically across Charon, which have since been the focus of my work.
