Making Space Accessible with Celene Shimmen
How do you go from a small town in Colorado to being a scientist-astronaut candidate in Australia? And how can you make space accessible for disabled astronauts? To find out, Dr. Charles Liu and co-host Allen Liu welcome scientist-astronaut candidate Celene Shimmen.
As always, though, we start off with the day’s joyfully cool cosmic thing, the new study using the James Webb Space Telescope that disproves the detection of tryptophan, a complex amino acid, in the interstellar cloud IC 348. Or, as Chuck jokes, no sleepy turkeys in space.
Then we get to meet Celene Shimmen, who is a scientist-astronaut candidate in Australia. She’s a physical therapy student who is already putting her research to work in the space industry.
Celene describes how she recently designed and implemented the Lower Extremity Motor Coordination Test in Microgravity for AstroAccess, a project she works with dedicated to promoting disability inclusion in human space exploration by paving the way for disabled astronauts. (You may remember Cady Coleman talking about working with AstroAccess in our recent episode, Sharing Space with Astronaut Cady Coleman, Part 1. [INSERT APPROPRIATE LINK]
You’ll hear about Celene’s acceptance into the scientist-astronaut training program for suborbital missions with the International Institute of Astronautical Sciences, beginning in 2023. She tells us about her upcoming parabolic flight where she’ll be the principal investigator testing balance differences after acute exposure to weightlessness. Chuck asks whether the “Vomit Comet” is aptly named - Celene explains that she’ll have to let us know, since her upcoming flight will have 16 periods of microgravity.
Our first question comes from Anne, who asks, “What are some psychological or physical traits that make for a good astronaut?” Celene highlights the importance of training for strength, endurance, balance, and cardiovascular fitness, especially for upcoming, long-term missions on the moon. It turns out that while the moon has lower gravity, the encumbrance of spacesuits requires greater strength and endurance. Allen explains that lesser gravity doesn’t mitigate some aspects of force and inertia that also require physical strength.
Celene describes the psychological aspects of being an astronaut, and the need for mental resilience to cope with isolation and stressful situations, as well as problem solving skills and the ability to work as part of a team.
You’ll also find out about Celene’s journey from growing up in a single-wide trailer in a town of 1000 residents in Colorado to studying hospitality in the Disney College Program in Florida, where she met her Australian husband. After watching “First Man”, the movie about Neil Armstrong, Celene decided she wanted to get into the space program. She applied to and was accepted by the Melbourne Space Program, working on a nano-satellite program. She also helped a humanoid robot take its first step, which inspired her to get involved with physiotherapy and the human body in space.
Our next question is from “anonymous”: What part of the human body is most vulnerable in space? Celene explains that extended exposure to microgravity leads to muscle atrophy and bone density loss, which is still a big issue even with ongoing exercise. Even just a 14-day stay in space leaves returning astronauts with muscle weakness.
Finally, we hear about Celene’s desire to be deployed to the moon, should the opportunity arise. Upcoming lunar missions to the moon will likely last about 30 days each, including 7 days of activity on the lunar surface.
If you’d like to reach out to Celene and chat, you can follow her on Instagram @spaceptcelene and on LinkedIn and Facebook as Celene Shimmen.

As someone who used to he able to longboard and skate, when i had spinal surgery. All the muscle mass in my legs disappeared within a couple of weeks. Relearning to walk sucks!
Fun fact, Florida is not entirely flat, once you go past central Florida above the Ocala area, is what we call the rolling hills. We even have a cave available for touring that's about 45 minutes to 1 hour away, going west from Jacksonville

I came here to battle Allen Liu again... Just kidding. Chuck, I saw an old video of yours where you showed the spin of a planet shifting from pointing North to South and vice-versa. It's similar to my drawings.
It should get more views wtf

Lovely stepwise intro to the galaxy clusters, thank you! And I love the vibe of your show.
Very exciting.
My theory Is that Gravity Is born of the Solid State. When subatomic matter overheats and switches Atomic electromagnetic spin around the nucleus ⚛️, such internal subatomic spin must now reconfigure itself into a polarised solid, with no more spin, instead a North and South Pole with a nuclear energy Plasma core. Gravitational Force Is basically the baby of the Electromagnetic Force and the S&W Nuclear Forces. Quantum Gravity being too weak to add mass, cannot overcome the stable Subatomic Spin. But once overheated into solid Mass, Gravity begins to have more Power, enough to gather more mass, that cannot be combated by the rigid polar regions and a nuclear core, as opposed to the Proton Electron Neutron spin around a Nuclei remaining stable, and too strong for quantum gravity to interfere. The State of Matter change causing a readjusted Electromagnetic and Nuclear process likely enhances Gravity. Which Is possibly why they’re still considered stronger Fundamental Forces even in the Astronomical. Congratulations, it’s a beautiful baby Gravity. Have you chosen of a name yet?
You’re awesome
Liu, I've gone beyond. Have you ever wondered how a direction stores and passes on positional values or data from other directions? Say that you have a forward ticking direction from 1 tick to 10 ticks. It has no other directional storage, so anything else is null or non-existent. If you introduce an upward direction, you'll only be able to use upward values for upward direction. So, how does forward know where to meet upward on a graph? Unless there is something else connecting them ,or there is a general direction that stores any directional value, because I can't say that this forward at 9 has an upward value of 3. Forward is only one dimensional and never has an upwardness ever. What do you think? You can tell Neil that I asked if he knows anything about it.
Even if I rotate the forward directional vector super fast to mimic a two dimensional circle, it won't be able to move upward.
Hey, Allen here! This is a super fun mathematics question that gets into the realm of linear algebra and topology. Usually when you have a system with two variables there's one obvious way to describe the system, but there are other valid descriptions as well. If I have 9 apples and 4 oranges and I wanted to describe that with a pair of numbers, I would usually say (9,4). I could instead, however, say I have 13 total fruits and 5 more apples than oranges and describe that as (13,5). As long as I know the math to convert from one system to the other, I can use either just fine. The math of linear algebra says that changing your reference frame for your position in space, like for example by rotating, moving to a new location, or changing what speed you're going, is just changing which numbers you're using to describe the same underlying system. So if you rotate yourself so "up" and "forward" change for you, your new up and new forward are just different combinations of your old up and your old forward. Isaac Newton figured out that what makes space so special is that there's no one "up" and "forward" (or left and right) that's more special than the rest, but that any perspective where you aren't accelerating is equally valid. Physicists say this as that there's no "preferred reference frame". Albert Einstein realized this more generally applies to the combination of space and time (spacetime), but you have to treat time as in some sense the negative of the three directions of space. It's pretty cool that by thinking about these questions we can get to the same problems that made Newton and Einstein's careers. What makes them so important to science is that they figured out the math and the experiments to back it all up and confirm their ideas.
@@TheLIUniverse I appreciate your reply Allen, but I'll have to respectfully disagree with some notions and agree with some. Fruits, and equivalence of rotation to acceleration with shifting positions, I agree.Yet, I don't know if it is accurate to assume there is a more general direction because we still haven't answered how a forward one dimensional vector reacts to an independent upward one. Isaac Newton's notion of non-acceleration frame, negatives..., I do not agree while residing in a rotating galaxy. Both Einstein's and Newton's notion that there is no significant preferred directional vector over another... I'm in total disagreement, Allen Liu... respectfully. Later on, I'll clarify myself to LiUniverse with real and thought experiments that even you can do anywhere at anytime.
Totally ok to have respectful disagreement - that's how we build knowledge as a planet. I will add that the rotation of the galaxy does matter but it's a very slow effect since it takes millions of years to spin once. Even detecting the rotation of the Earth on the scale of a few feet or meters is doable but hard - you can watch Veritasium and Smarter Every Day's video on how they found the Coriolis effect in a kiddie pool to get a sense of just how hard. So standing on Earth is very close to being a non-accelerating frame, even if it's not quite there. --Allen (Also P.S., would you want us to talk about your question in a future episode?)
@@TheLIUniverse Sure, you can use it. It's okay to realize going from 0.00000001nm, 0.000000012nm, then 0.00000002nm is still acceleration. It's not a matter of scale in size, but the progress and tracking of moving from one location to another. Acceleration is acceleration. Isaac Newton's integrals should be ignored then if that's the case.
Love the show!
Didn’t know you had a channel of your own as well! Always watched you on Star Talk. Glad I can hear more from you here. Also, would be great if Star Talk can give a plug to your channel if they haven’t already.
Dr. Liu you are awesome in every way. I love it when you get philosophical
Chuck and Allen! I was excited to see this new episode! Thank you for the terrific content!

Thanks, as a trained musician and armchair physics and astronomy consumer, this was fun. More or less, I'm a jazz player, and the second music clip from Bruce's music reminded me of the chords you hear in jazz in terms of typology and voicing. Additionally, the music was beautiful overall in its short clips.
Thank you for your comments and for noticing the jazz elements in my work. I’m not a jazz musician but I love jazz, have made a deep study of jazz harmonies and improvisational melodic phrases, and over the decades have integrated these elements into my musical thinking. So I don’t think consciously of jazz any more; it just comes out that way, mixed in with other influences.
Hey Chuck, saw you multiple times on star talk and been a fan of you since. Love ya knowledge and personality
A science is a subject that has fundamental truths that have been proved true over the years. An art is a subject you learn and perfect over the years with hours of practice. Sometimes we have overlaps, like maths. Sometimes we have to use arts to articulate large parts of a science. Sometimes we start with scientific principles and practice the thing to death.
Got your 6. From Star Talk
❤?❤ Do you want to see a clean Universe without noise pollution? Where is the scientific interest and curiosity for new experiences? BIG ERROR in measuring the Universe, black holes, dark energy,... Let me judge all this by the result of a direct experiment, gentlemen of physics Let's do the Michelson-Morley experiment on a school bus and determine the speed in a straight line - this is exactly the experiment Einstein dreamed of. Perhaps we will see the postulates: “Light is an ordered vibration of gravitational quanta, and Dominant gravitational fields control the speed of light in a vacuum.” There is a proposal for the joint invention of a HYBRID gyroscope from non-circular, TWO coils with a new type of optical fiber with a “hollow core”, where - the light in each arm passes along 16,000 meters, without exceeding the parameters of 0.4/0.4/0.4 meters and mass - 4,4 kg.
Riemann died in 1866. Einstein was born in 1879
Chuck is my favorite person on UA-cam. Seems to me that he might be the most unbiased open minded human alive today. Thanks Chuck.
That will be a nice birthday present to me
after a violent weekend of fights I need to revert to my NERD to calm my T LEVEL and what better Geek and Chief to calm my levels down with brain exercise and a smile.
Yes, he had to brainwash himself into it. It's a shame his learning story. I like his gravitation and the sound analogies because I already know about it from my own insight. The orientation is what I'm keenly interested in now, then I'll work on my artificial gravity density.
Due to the Earth's rotation these episodes tend to be uploaded just before the waking hour in my neck of the woods and this is the best coffee to wake up to. Another great, informative vid, full of thought provoking science and art. Thanks for the good work LIUniverse! 💙
Science is Art and Art is Science! Two things entangled in a beautiful dance. Keep up the great work!
Thank you!
