rising star What kind of outreach activities do you do? When and why did you become interested in astronomy and space? Anything from speaking at local schools and libraries, keynoting at star parties or adult group societies (Lifelong Learners, etc.) to having a mini radio show on local NPR about cool stuff in our solar system. The most rewarding part in doing outreach is reaching out to all levels of society and seeing a sense of curiosity for science in the community! I have my father to thank for that. When I was 9, he got me my first telescope and membership into the Central Appalachian Astronomy Club based out of West Virginia. From there, it’s like a second family to me. They ask me to come back over the summer and give talks to their club and their star parties. I formed such a relationship with the members of the club and through them I’ve met astronauts. I’ve gotten to talk with members of SETI. From the club, I’ve learned not only space is cool, but also, on a networking level, I’ve gotten to meet so many different kinds of people in astronomy. What advice do you have for young people who are interested in the field of astronomy? My advice: If you’re curious about something, go for it. There’s no limit to just discovering something. You don’t have to wait to go to college to get a textbook, or to talk to a professor. Go do it! Talk with those who are as curious about it as you are. In the end, it’s YOUR science to discover and learn! 14 What do people seem to find most exciting at outreach events? The fun part about studying space geology is to study Earth geology. I think showing people how our own beautiful planet is giving us hints to what is going on on other planets is quite extraordinary. Bringing it (literally) down to Earth is fascinating! What does the future hold for you as an astronomer?

COURTESY OF Caitlin Ahrens What is the focus of your research? The focus of my research involves simulating ice geology on Pluto, such as what kind of ice and how the ice is transformed to make different kinds of geology, in my experimental simulation laboratory at the Arkansas Center for Space and Planetary Sciences. Earth doesn’t get that cold, and there’s certain ices that we can’t find here on Earth, so I can simulate it in my lab to see how ice interacts with other ices – methane, carbon monoxide, nitrogen, ammonia. They all act differently, especially when you mix all of them together. Sky ’ s Up Ahrens’ passion for planetary science began during an internship with the U.S. Geological Survey conducting astrogeology research. “They specifically wanted someone to look at dunes on Mars. It may not sound exciting – they’re big piles of sand on Mars,” Ahrens said of the experience. “At first, I was like, ‘Ah man, I wonder how this is going to pan out – large piles of sand.’ But no, it’s quite entertaining because if you’re looking at a sand pile, it could move and then you have to start over. Sand moves everywhere on Mars. That was a very entertaining process, and we also discovered a dune on Mars, so I was on the team to name a dune on Mars.” Here, Ahrens poses with a poster concerning the USGS research on Mars dunes. More outreach! More research! There is still so much we don’t know about our solar system. Planning more missions and getting researchers together to collaborate would be my goal!
