Inside the Human Exploration Research Analog, or HERA, crew member Jared Broddrick lifts a dumbbell equipped with adjustable colored weights, called a power block. The crew performs a mix of cardio and resistive exercises to stay in shape throughout the 45-day simulated journey to the Martian moon Phobos.
During a HERA mission, crew members have scheduled exercise time as do astronauts aboard the International Space Station. HERA includes two power blocks that can adjust to a maximum weight of 35 pounds. The power blocks require less room than a set of dumbbells, which helps save space in the compact habitat.

NASA’s Human Research Program, or HRP, pursues the best methods and technologies to support safe, productive human space travel. Through science conducted in laboratories, ground-based analogs, and the International Space Station, HRP scrutinizes how spaceflight affects human bodies and behaviors. Such research drives HRP’s quest to innovate ways that keep astronauts healthy and mission-ready as space travel expands to the Moon, Mars, and beyond.
