About
Steven P. Chappell is a NASA research engineer whose work sits at the intersection of human spaceflight operations, robotic systems integration, and analog mission testing. His research has been instrumental in shaping how NASA evaluates and prepares for deep space exploration, particularly missions targeting near-Earth asteroids and the Martian moon Phobos. Chappell's most significant contributions emerge from his leadership in NASA's analog mission programs, including the Desert RATS and NEEMO series — controlled simulations that test crew performance, habitat designs, and human-robotic collaboration under realistic mission constraints. His most cited work, "Desert RATS 2011" (48 citations), exemplifies this approach, rigorously assessing how astronauts and robots might jointly explore asteroid surfaces. Complementary studies through NEEMO 15 (31 citations) extended this evaluation to underwater environments mimicking microgravity conditions. Beyond asteroid exploration, Chappell has advocated for a Phobos-first strategy as a stepping stone to Mars surface missions, arguing the moon offers both scientific value and critical infrastructure-building opportunities. His work on NASA's NextSTEP habitation concepts further reflects his broader commitment to translating analog research into actionable deep space hardware standards. Collectively, his publications represent a foundational body of work guiding humanity's next era of exploration.
