Michael Mastin is the founder of Crater Exploration. Born and raised in Alaska, he has lived, worked, and traveled extensively throughout America, Asia, and the Pacific rim. He has work experience in aviation, marine transportation, heavy industry, photography, and served in the U.S. Army Special Forces "Green Berets" as a communications sergeant.  He currently works at the US Navy's SEAFAC submarine acoustic research facility in Ketchikan Alaska. ​A lifelong fascination with space exploration, a truly unique combination of industrial experience, and a personal network of people accustomed to working on small teams in remote and hostile environments to accomplish highly complex and technical missions led Michael to found Crater Exploration in order to facilitate the future manning requirements of the space exploration industry. He is tech diver certified, has a 100 Ton Master captains license, and is a graduate of the Project PoSSUM scientist-astronaut school and zero-g parabola flight testing program.                                                                                                                                                                                                                                                                     contact: mastinmichael@craterexploration.com  ​

Ulyana Nadia Horodyskyj has a PhD in geological sciences (specializing in glaciology) from the University of Colorado Boulder. Prior to entering the program at CU, she completed a B.S. in earth sciences from Rice University (Houston, TX), where she also worked at the Rice Space Institute and trained in the Navy ROTC program. She earned a Masters of Science in planetary geology from Brown University (Providence, RI).  
Ulyana has published several articles in scientific journals; presented her findings at conferences nationally and internationally; guided student expeditions for National Geographic; and taught glaciology in the North Cascades and Alaska for a "Girls on Ice" science and mountaineering program. From September 2013 - June 2014, as a recipient of a Fulbright fellowship, she logged 1000 miles and tens of thousands of vertical feet in Nepal, collecting data on growing and deepening glacial lakes and wind-borne pollution effects in snowpack on peaks. By age 23, Ulyana had visited all 7 continents, with a particularly unique experience in Antarctica working on a research icebreaker. Most recently she participated in the Project PoSSUM scientist-astronaut training program Class 1503 and as a space suit research participant in zero-g flight. She is also a member of the Explorers Club and the founder of Science In The Wild citizen science expeditions.
