What would it be like to go on a journey into deep space? 🤔 Meet (from left to right) Madelyne Willis, Christopher Roberts, Lauren Cornell, and Monique Garcia. From October 1 to November 15, 2021, these four volunteers lived and worked inside a unique, ground-based habitat at NASAJohnson Space Center in Houston. Designed to serve as an analog for isolation, confinement, and remote conditions in exploration scenarios, this small habitat is called the Human Exploration Research Analog, or HERA. Through work on HERA, scientists search for insights into a variety of questions. For example: Will the stress of being enclosed with little contact to the outside world take a toll on team dynamics? Will that same stress take a toll on crew health? Will virtual assistants and other new technologies created to help astronauts on deep-space missions work with HERA crew as intended? A new HERA mission with new crew will start on Jan. 28. Want to learn more? Join us for a Reddit Ask Me Anything ...
