Astronaut Nick Hague measures his mass using a specialized device

iss072e616386 (Feb. 11, 2025) --- NASA astronaut and Expedition 72 Flight Engineer Nick Hague measures his mass using a specialized device inside the International Space Station's Zvezda service module. The mass measurement device applies a known force to an attached astronaut and measures the resulting acceleration to acquire the crew member's mass. The result is based on a form of Newton's Second Law of Motion.
