Designer: A multi-center team led by NASA’s Johnson Space Center

Location: Anaheim, CA,US

Introduction: The project aims to integrate intelligent habitat systems and safety features to mitigate the effects of hazardous environments during long-duration space missions, provide adequate air and water, dispose and recycle waste, regulate temperature, secure food supplies, and support physical exercise. the HDU project uses intelligent habitat systems to reduce reliance on crew and ground control for monitoring and maintenance through software and smart sensors.

NASA put its second habitat architecture concept – the Habitat Demonstration Unit–Deep Space Habitat(HDU-DSH) through carefully controlled test at the Johnson Space Center, and claimed that they would further put it into the Arizona desert, where the arid climate, harsh winds and rocky terrain provide a fitting analog for extra-planetary surfaces in the annual Desert-RATS tests.

• Functions: power, thermal, avionics, lighting, and communications
• Layout: From the plan Fig. we can see that a single modular is basically divided into 8 sections. Areas include geological laboratory, general maintenance workstation, medical operations workstation, EVA suit maintenance workstation, airlock,hygiene module,dust mitigation module and EVA porch. Rested hatches can be used to connect to other units during habitat expansion.
