<h5>Humans went to Mars?</h5><p>Doesn’t sound real, does it? A group of humans staying all alone on a different planet than us? Well, <a target="_blank" rel="noopener noreferrer" href="https://www.newsahoot.com/articles/four-humans-will-begin-living-on-mars">four humans were sent to Mars by NASA</a> to live there for a year and recently returned to Earth.</p><p>But there’s a twist to it. The crew of four were not actually living on the red planet. Instead, they lived in a Mars-simulated environment at NASA’s Johnson Space Center in Houston, USA.</p><p>The Crew Health and Performance Exploration Analog (CHAPEA) mission crew stayed in the artificial Mars-like habitat for 378 days.</p><figure class="image"><img alt="CHAPEA.jpg" src="https://storage.googleapis.com/newsahoot.appspot.com/CHAPEA_65313e4f4b.jpg"><figcaption>The crew of the first CHAPEA mission.

Video by VideoFromSpace.</figcaption></figure></div><p>The crew members lived in an isolated 1,700-square-foot (imagine it as big as a huge flat), 3D-printed habitat that simulated a real-life Mars-like environment.</p><p>The habitat layout was designed to provide separate areas for living and working. There were private living areas for the crew, a kitchen, bathrooms, and specialised places for medical, recreation, fitness, work, and crop-growing activities.</p><h5>What did the crew do?</h5><p>During their year-long stay on the surface of fake Mars, the crew carried out various mission objectives.</p><p>This included simulated walks on the Martian surface, habitat maintenance, robotic operations, exercise, and crop growth. They also faced intentional environmental problems like resource limitations, confinement, etc.</p><p>The mission was also designed in such a way that it simulated all of the obstacles that a crew could face on Mars. The mission also helped scientists understand how living in another world might affect human health and performance.</p><h5>About CHAPEA missions.</h5><p>CHAPEA is a series of missions designed to imitate year-long stays on the surface of Mars. Each expedition will consist of four crew members living in the Mars Dune Alpha (the artificially created Martian habitat).</p><p>During each mission, the crew members will conduct various experiments to help scientists understand various factors about living on another planet.</p><p>Two more missions are planned after the conclusion of the first one, with the second one scheduled to begin in 2025.</p>

The crew lived in an artificially created Martian environment.
