NASA has unveiled the second Crew Health and Performance Exploration Analog (CHAPEA) habitat, designed for a series of analogue missions simulating year-long stays on the surface of Mars. The second mission is scheduled to begin in late 2025. Each mission consists of four crew members living in the CHAPEA habitat, an isolated 1,700 square foot, 3D-printed structure. During the mission, the crew will conduct simulated spacewalks and provide data on various factors, including physical and behavioural health and performance.Suzanne Bell, NASA behaviour health expert and CHAPEA co-investigator, spoke about the technologies they are using on Friday. "So here in CHAPEA, this habitat was 3D printed. This is one of the technologies we're exploring for how we might build a habitat someday on Mars. 3D printing technology could be an important technology. The reason is that we would be able to use resources within Mars, such as the Mars regolith, and then make a building out of it," she said. Dana Gardner, NASA Exercise Physiologist, spoke about how astronauts stay fit in space. "Of course, here on Earth we have gravity, and so on Mars we're going to have partial gravity. So, exercise is really key still to do that on Mars for the sake that we want to ensure mission success. We know that there's going to be, you know, a lot more EVAs. We want to make sure that cognitive health is good, and we know that exercise helps with all of those things."
00:00So here in Chapia you're looking at the wall and this habitat was 3D printed. This is one of the
00:15technologies we're exploring for how we might build a habitat someday on Mars. 3D printing
00:20technology could be an important technology. The reason is is because we would be able to
00:25use resources within Mars, such as the Mars regolith, and then make a building out of it.
00:37A multiple airlock system. Just like you'd expect on Mars, dust mitigation is an important feature and
00:43so we do that here. So we'll ask you to come through the airlock, then we'll shut the doors
00:47behind us and continue through before we go on to the Martian surface.
00:50Expect here, then we wouldn't be getting good data. We have one more airlock to go through.
00:58These are movable solar panels that the crew would be working on, on their spacewalks.
01:20When you go to Mars someday, we would like them to be able to do long traverses and walks across the
01:26Martian surface. And so we're able to extend that through virtual reality. So here we have
01:32them do up to six hours spacewalks through virtual reality.
02:02So of course here on Earth we have gravity and so on Mars we're going to have partial gravity. So exercise
02:16is really key still to do that on Mars for the sake that we want to ensure mission success. We know that there's going to be, you know, a lot more EVAs. We want to make sure that cognitive health is good and we know that exercise helps with a lot of
02:30things.
02:48Privacy is important. So a crew lives and works together nonstop for over a year.
03:18So they need private chambers to go to. These are our private chambers for each crew member.
03:25Ramone is the best time.
03:36So you don't get there.
03:38It's about 140 SHOW after China and가-
03:41swimming.
03:43So it's important for us to be able to sustain performance and meet our mission objectives
04:03that people do get their downtime and they're able to disengage.
04:06So they do recreational activities, whether it be games, whether it be something that
04:11they're watching, whether it be video games.
04:13And the idea is that you do need to disengage so the next day you can come at that schedule
04:17again and give it your all so we can do important things like spacewalks.
04:34And we have virtual reality and non-virtual reality spacewalks.
04:39For the non-virtual reality spacewalks, they can bring in their different rock samples
04:45and other samples that they take and do experiments on it to better understand the Martian surface.
04:51As mentioned, the communication delay is extreme.
04:55So any emergence, we are doing tech development testing on important technologies such as
05:01artificial intelligence medical aids and looking at how the crew is able to use those and providing
05:06feedback in terms of making the next generation of those to make it more helpful for the crew
05:11to autonomously address those medical challenges that we might expect someday on Mars.
05:16From an immune perspective, we know that the astronauts have some level of immune
05:28compromise during spaceflight.
05:30It's an interesting phenomenon.
05:32Some of the immune cells don't work.
05:33There's a persistent inflammation.
05:35And we're concerned about clinical risks for deep space missions.
05:39So in an analog like this, they help us characterize this.
05:42We're one of the performance metrics that is being looked at in the Chapia Analog.
05:48But it's a very integrated study.
05:56And so obviously the isolation, the long duration, these are the things that make Chapia such an
06:02amazing analog and aid us in characterizing the effects that those stressors in concert have
06:08on human physiology.
06:09We actually do so much, people 12 times in the face when they think of wearing this direct
06:12thing.
06:14And so we're led to the everyone watching.
06:16This would be happening as we're all dialing to it.
06:16And so on with what our culture see here on Mars is a
06:25spot.
06:25So what I
06:35want to do is let the human being of each other
