** NASA Groundlink: Q&A with Crew Isolated in HERA Habitat (C6M4) – NASA Johnson
Crew members Sandra Herrmann and Katie Koube, from HERA Campaign 6 Mission 4, answer questions from students all over the world. NASA’s “Groundlink” series connects students with crew currently inside NASA’s Human Exploration Research Analog, or HERA, a habitat here on Earth. Through simulation of long-term human space travel, these crew are on a mission to help scientists learn more about how isolation, confinement, and remote conditions will affect astronauts on Artemis missions to the Moon and on future missions to Mars.
Similar to educational Downlinks, which connect students with astronauts aboard the International Space Station, Groundlinks give students the opportunity to ask HERA crew their questions. Through the crew’s answers, students can learn more about how NASA prepares humans to live and work in space.
NASA’s Human Research Program pursues methods and technologies to support safe, productive human space travel. Through science conducted in laboratories, ground-based analogs, and the International Space Station, this team scrutinizes how spaceflight affects human bodies and behaviors. Such research drives NASA’s quest to innovate ways that keep astronauts healthy and mission-ready as space travel expands to the Moon, Mars, and beyond.
