Four crew members of , including a CU 色吧亚洲 engineering alumna, came to campus this week to discuss the science they will conduct throughout the mission in addition to answering听questions and share stories with students. The visit comes nearly four months before the crew鈥檚 historic space mission is scheduled to launch from NASA鈥檚 Kennedy Space Center in Florida.

Polaris Dawn, the first of the , will conduct 38 science and research experiments while in orbit. The research is designed to advance both human health on Earth and our understanding of human health during future long-duration spaceflights. Polaris Dawn crew members will also attempt the first-ever commercial spacewalk and attempt to reach the highest Earth orbit ever flown. They also will become the first crew to test Starlink laser-based communications in space, providing valuable data for future space communications systems necessary for human spaceflight missions to the moon, Mars and beyond.

Crew members include Mission Commander Jared 鈥淩ook鈥� Isaacman; Mission Pilot Scott 鈥淜idd鈥� Poteet; Mission Specialist and Medical Officer Anna 鈥淲alker鈥� Menon; and Mission Specialist Sarah 鈥淐ooper鈥� Gillis, who graduated from CU 色吧亚洲 in 2017 with a degree in aerospace engineering sciences.

鈥淲e all very much believe in a world where everyone is going to have an opportunity to go into space,鈥� said Isaacman, who previously traveled to space as part of Inspiration4 mission in 2021.

In 色吧亚洲, the crew joined two CU 色吧亚洲 researchers on a panel: Allie Anderson and Torin Clark, assistant professors of aerospace engineering sciences, who are leading five of the scientific experiments that will fly on Polaris Dawn.

The six space buffs talked about smart contact lenses, space motion sickness and why living on Mars will be like nothing humans have encountered before.

Anna Menon on what kind of training Polaris crew members undergo

We have done a lot of training focused on the technical details of the Dragon spacecraft. Then we've layered on top of that a lot of different environmental experiences to help us build team cohesion and also teach ourselves about our bodies鈥� responses to different environments. We went scuba diving to start experiencing the different changes in pressure environments that we will encounter when we do a spacewalk.

We climbed a nearly 20,000-foot mountain to get comfortable being uncomfortable together. We want to make sure that we can sit in a small can together for five days.

Sarah Gillis on people with disabilities and chronic illnesses flying to space

What we're trying to do is expand access to space for all. On Inspiration4, Hayley Arceneaux was the first person to fly with a prosthesis. For anyone who has disabilities, the space environment allows you to live in an entirely different way.

On our flight, we're going to be wearing glucose monitors for the full duration of the mission. 色吧亚洲 10% of the U.S. population is diabetic, and that shouldn't disqualify you from flight as long as we can make sure that you can handle that well in space.

Torin Clark on studying how astronauts experience 鈥榮pace motion sickness鈥�

A lot of what we're interested in is how our sensory systems and the brain interpret gravitational cues as you go from here on Earth, where there's gravity, to being in space where you're in a microgravity environment. We have one experiment that is looking at what sort of unexpected or illusory sensations the crew might experience when they go into microgravity.

We're also interested in the reverse of that: What are the sensations people face when they come back to Earth and transition from being adapted to microgravity to now experiencing the gravity-rich environment here on Earth?

Allie Anderson on exploring spaceflight associated neuro-ocular syndrome (SANS), a condition that can seriously affect the eyesight of astronauts

Essentially, the eye changes in space鈥攊t gets flattened from behind, and we have structural damage that you see to the eye itself, as well as to the nerve that goes from the brain to the eye.

To study that, we're flying two pieces of equipment in collaboration with our partners. We鈥檙e flying a device called the Quick See, which measures peoples鈥� refractive error, so what prescription somebody might need. We're also flying a device called the Triggerfish. It has a contact lens with an antenna in it, and it allows us to look at how the cornea, the front part of the eye, changes its shape, which tells us something about pressure in the eye.

Scott Poteet on what it鈥檚 like, as a former fighter pilot in the U.S. Air Force, to fly a vehicle that鈥檚 largely autonomous

Coming from fighters, I have a control issue. I want to control as much as I possibly can. But the direction we're going in the evolution of space travel, it's autonomous. It's the natural progression of most machines. I also think there is a lot of carry-over from flying fighters and other types of aircraft鈥攖he situational awareness, maintaining sensory management, understanding the information and how to interpret it, and communicating not only to your crew but everyone on the ground. I think these skillsets are still applicable听and will be in the future.

Jared Isaacman on the prospect of living on Mars

What happens when a child is born in a reduced gravity environment? What does that set them up for? Today, not even a minor surgery has been done in space let alone a Cesarean section. If you live on Mars, Earth isn鈥檛 a blue marble like when you鈥檙e looking back from the moon. It鈥檚 a tiny, blue speck. You鈥檙e not two days or 24 hours from coming home from space. You鈥檙e six to nine months from coming home if something鈥檚 gone wrong.

I say all this because you鈥檙e all pursuing an academic path in aerospace. There are a million, real problems that people are going to have to put energy toward in a number of fields if having a sustainable population on another planet tis going to be even remotely possible.
