The rover captured a mosaic of "Pinestand," where layers of sedimentary rock could have been formed by a deep, fast-flowing river. In the meantime, robotic explorers are hard at work uncovering some of the secrets of the red planet. Many items remain on the checklist before humans can safely reach Mars. The simulation will also focus on nutrition and psychological and physiological tests for the crew. They’ll live like astronauts while responding to unexpected equipment failures and other surprises that might crop up during life on Mars. For a year, four volunteers won’t leave the inside of the base. ![]() The 3D-printed habitat resembles what the first human crews might use while exploring Mars. ![]() The Crew Health and Performance Exploration Analog will kick off in June at Johnson Space Center in Houston. The simulated experience is the foundation of NASA’s latest experiment, called CHAPEA. Soon, four researchers will have the chance to live inside a Martian base, without enduring a long spaceflight or ever setting foot on the red planet.
