Houston, we have a podcast. Welcome to the official podcast of the NASA Johnson Space

Center episode 311 Mars Audio Log number 3. I'm Gary Jordan, I'll be your host today.

On this podcast, we bring in the experts, scientists, engineers, astronauts, all to let

you know what's going on in the world of human spaceflight and more. We're back with

another audio log from the Chapea crew. Chapea, or crew health and performance exploration

analog, is a year-long analog study in a habitat here right on Earth that is simulating

very closely what it would be like to live on Mars. We're lucky enough to have monthly

check-ins with the crew, Commander Kelly Hastin, Flight Engineer Ross Brockwell, Medical Officer

Nathan Jones, and Science Officer Anka Salariu. To meet the needs of fitting in with this

analog and simulating significant communication delays between Earth and Mars that prohibit us

from having a live conversation, the crew is recording an audio log based off of questions

that we draft for them. On this episode, we'll play the recording of their third month in the

habitat, which is here at the NASA Johnson Space Center and was recorded in September 2023.

We'll also be bringing on a special guest to learn even more about Chapea. If you've been

tuning into these logs, you know that they talk a lot about food. One of the scientific objectives

of this analog is better understanding a Mars food system, but there are many layers to that.

One layer is nutrition, and one of the scientists looking for data of this particular mission is

Dr. Scott Smith, NASA nutritionist, Chapea co-investigator, and manager of nutritional biochemistry

here at the Johnson Space Center. So with that, let's learn from the Chapea crew on how they're doing,

and Scott Smith on the Chapea Nutrition Science. Let's get into it.

All right, first is Chapea Mission Commander, Kelly Hastin.

Hi, my name is Kelly Hastin. I'm the commander of Chapea 1, a one-year-long Mars Analyb Mission
