Rachel developed a love of astronomy at a young age. Growing up on a farm allowed for an amazing view of the night sky.  Unfortunately, a move to the city added a lot of light pollution.  Eventually, RC got her own telescope and learned new ways to study the sky with radio astronomy.  She became a certified amateur radio operator and is currently working to combine optical and radio images of outer space. Rachel joined Project PoSSUM in class 1901. Following her dream, she earned her private pilot’s license and achieved Padi’s Master Scuba Diver’s training to understand the unique challenges and needs of spacesuits. Rachel is building upon a strong background in space science and cybersecurity.  Her current endeavors are founded on an extensive academic background with a BA in Political Science from LaGrange College, an MSc in Space Management from the International Space University in Strasbourg, France, and a MA in Intelligence with a cyber focus from the American Military University.  Currently, RC is pursuing a BS in Computer Networks and Cybersecurity from the University of Maryland Global Campus.
