The crew of a NASA mission to Mars abandoned their spacecraft after a year-long journey during which they never left Earth.
The four volunteer crew members spent more than 12 months in NASA’s first simulated Mars environment at the Johnson Space Center in Houston and left the artificial environment around 5 p.m. on Saturday.
Kelly Haston, Anca Selariu, Ross Brockwell and Nathan Jones entered the 3D-printed habitat on June 25, 2023 as the space agency’s first crew. Crew health and performance – analog exploration Project.
Haston, the mission commander, began with a simple “Hello.”
“It’s just so wonderful to be able to say hello to all of you,” she said.
Jones, a physician and missionary doctor, said the 378 days in captivity “went by quickly.”
The quartet lived and worked in a 157-square-meter space to simulate a mission to the Red Planet. The Red Planet is the fourth planet from the Sun and is often the focus of discussions among both scientists and science fiction fans about a possible human journey beyond our Moon.
The first CHAPEA crew focused on creating possible conditions for future Mars operations through simulated spacewalks (called “Marswalks”), growing and harvesting vegetables to replenish their supplies, and maintaining the habitat and their equipment.
They also overcame the challenges a real Mars crew would face, including limited resources, isolation and communication delays of up to 22 minutes with their home planet on the other side of the habitat’s walls, according to NASA.
Two more CHAPEA missions are planned and the crews will continue to conduct simulated spacewalks and collect data on factors related to physical and mental health and performance, NASA said.
Steve Koerner, deputy director of the Johnson Space Center, said most of the first crew’s experiments focused on nutrition and its effects on performance. The work is “critical science in preparing for the flight of humans to the red planet,” he said.
“They were separated from their families, placed on a carefully prescribed diet and subjected to strict observation,” Koerner said.
“Mars is our goal,” he said, calling the project an important step in America’s efforts to take a leading role in global space exploration.
When Kjell Lindgren, an astronaut and deputy director of flight operations, knocked on the habitat’s door, the four volunteers came out and talked about their gratitude for each other and for those waiting patiently outside, and about the lessons they had learned about a possible manned mission to Mars and life on Earth.
Brockwell, the crew’s flight engineer, said the mission showed him the importance of sustainable living for the benefit of all people on Earth.
“I am very grateful for the incredible opportunity to spend a year living in the spirit of planetary adventure towards an exciting future, and I am grateful for the chance to live the idea that we must not consume resources faster than they can be replenished, and we must not produce waste faster than it can be processed back into resources,” Brockwell said.
“If we don’t live these principles, we can’t live, dream, create or explore for any length of time, but if we do, we can achieve and sustain amazing and inspiring things, like exploring other worlds,” he said.
Science officer Anca Selariu said she had often been asked why the fixation on Mars was so great.
“Why go to Mars? Because it’s possible,” she said. “Because space can unite us and bring out the best in us. Because it’s a crucial step Earthlings will take to light the way for centuries to come.”
