HRP uses several <a href=\"https:\/\/www.nasa.gov\/analog-missions\/\">ground-based analogs<\/a> including: :envihab in Germany, Antarctic Stations, NEK in Russia, the Human Exploration Research Analog at NASA\u2019s Johnson Space Center in Houston, and the NASA Space Radiation Laboratory in Brookhaven, New York. These analogs offer a wide variety of environments to study how humans or biological samples change or adapt to spaceflight hazards. Researchers study how isolation and confinement affect mental health, or how weightlessness and artificial gravity influences physiology, or how space radiation may damage biological systems.<\/p>\n\n\n\n<p><strong>Step 2:<\/strong> The<a href=\"https:\/\/www.nasa.gov\/international-space-station\/\" target=\"_blank\" data-type=\"URL\" data-id=\"https:\/\/www.nasa.gov\/international-space-station\/\" rel=\"noreferrer noopener\"> space station<\/a><a href=\"https:\/\/www.nasa.gov\/mission_pages\/station\/main\/index.html\"> <\/a>serves as an international scientific laboratory and a unique environment to study the interaction and effects of some of the hazards of human spaceflight. Space station studies provide insight into how the human body adapts to weightlessness and hostile\/closed environments. Knowledge gained from space station missions is helping us better understand how astronauts adapt to long-duration spaceflight.<\/p>\n\n\n\n<p><strong>Step 3: <\/strong><a href=\"https:\/\/www.nasa.gov\/humans-in-space\/artemis\/\">Artemis missions<\/a> will allow researchers to study how deep-space radiation, a partial gravity environment, and distance from Earth affect astronauts\u2019 health and performance. NASA\u2019s Space Launch System rocket, or <a href=\"https:\/\/www.nasa.gov\/humans-in-space\/space-launch-system\/\" data-type=\"URL\">SLS<\/a>, will carry astronauts onboard the <a href=\"https:\/\/www.nasa.gov\/humans-in-space\/orion-spacecraft\/\">Orion <\/a>spacecraft to an outpost called <a href=\"https:\/\/www.nasa.gov\/in-lunar-orbit\">G<\/a><a href=\"https:\/\/www.nasa.gov\/mission\/gateway\/\">ateway<\/a><a href=\"https:\/\/www.nasa.gov\/in-lunar-orbit\">.<\/a> Gateway will house astronauts on Artemis missions in lunar orbit and enable crews to make trips to and from the Moon\u2019s surface with a <a href=\"https:\/\/www.nasa.gov\/general\/what-is-the-artemis-program\/\">human landing system<\/a><a href=\"https:\/\/www.nasa.gov\/what-is-artemis\">.<\/a> By using Artemis missions as a testbed for Mars, researchers will better understand how astronauts would accomplish medical operations, adjust to the surface of another celestial body, and keep necessary supplies like food and medicine safe for extended durations in deep space.<\/p>\n\n\n\n<p>Together, analogs, space station, and lunar mission studies are helping NASA turn dreams of stepping foot onto Mars into a reality.<\/p>\n\n\n\n<p class=\"has-text-align-center\"><code>_____<\/code><\/p>\n\n\n\n<p>NASA’s <a href=\"https:\/\/www.nasa.gov\/hrp\/\" data-type=\"URL\" data-id=\"https:\/\/www.nasa.gov\/hrp\/\" target=\"_blank\" rel=\"noreferrer noopener\">Human Research Program<\/a>, or HRP, pursues the best methods and technologies to support safe, productive human space travel.
