Casey has extensive experience in analog space environments, having taken part in 2 NASA Human Research Program studies. In 2014, he was selected to lead the 2nd Hawaii-Space Exploration Analog and Simulation (HI-SEAS), a 120-day isolation experiment. During HI-SEAS, Casey led a team of 5 international scientists, managing the tasks prescribed by the PI and mission support element. His crew planned and executed over 60 simulated EVAs on Mauna Loa volcano.  In 2016, Casey took part in the 10th iteration of the Human Exploration Research Analog (HERA) as a mission specialist at Johnson Space Center (JSC) in Houston, Texas. That mission simulated a 30-day deep space trajectory to a near-earth asteroid, where he conducted simulated EVAs and geoscience experiments.
