Biography

Dr. Chappell grew up in Lako Orion, MI, and attended the University of Michigan and earned a bachelor’s degree in Aerospace Engineering Sciences. Steve also earned master’s and doctoral degrees from the University of Colorado, studying human performance in simulated reduced gravity. Steve currently works for Wyle Science, Technology, and Engineering Group at NASA JSC. He is helping to define and execute the research needed to optimize human performance in the next-generation human space exploration systems, including leading and taking part in studies in exploration analog environments.

He was an aquanaut member of the crew for NEEMO 14. For NEEMO 15, he was a major contributor to the design of the equipment and methods the crew used and served as the Deputy Mission Manager for the mission. He was the Exploration EVA Technical Director for NEEMO 16, with responsibility for proper planning, preparation, and execution of all the mission’s in-water studies. He has been a participant in other analogs including the Haughton Mars Project and Desert RATS.

In addition, Dr. Chappell has been a active member of Rocky Mountain Rescue in Boulder, CO, since 1998. Rocky Mountain Rescue is one of the busiest all-volunteer mountain rescue teams in the United States. He has progressed in recent years to be the teams Operations Director and has taken part in more than 450 mountain rescue missions during his rescue career.
