Welcoming Assistant Professor Vishala Arya Jeff Zehnder Tue, 01/14/2025 - 14:37

The spring 2025 semester is bringing a new faculty member to Smead Aerospace.

Vishala Arya is joining the Ann and H.J. Smead Department of Aerospace Engineering Sciences at CU ��«��Ƶ as an assistant professor in the Colorado Center for Astrodynamics Research.

Before this role, she worked at the Mission Design and Navigation Section at JPL, focusing on stochastic trajectory optimization for the Europa Clipper mission and sensor de-noising, data ﬁltering, and center of mass calibrations for the GRACE-FO mission.

Arya earned her PhD in spacecraft dynamics and control and her master’s focused on robotics from Texas A&M University, where she developed advanced interplanetary trajectory optimization constructs and autonomous covariance constrained guidance algorithms for spacecraft. Her work introduced novel extensions to classical optimization methods for non-linear systems with inequality constraints, state and control discontinuities and abrupt time triggered events.

Drawing on her multi-disciplinary experience in space missions, soft robotics, industrial engineering, bioastronautics, and sustainable engineering, her research vision is to conduct comprehensive optimization of space systems.

She aims to co-optimize trajectory, spacecraft, payload, and logistics under uncertainty with robust optimization algorithms for autonomous, fault-tolerant system design. Her focus includes campaign-level mission design optimization strategies that foster cooperation among multiple satellites or agents and demonstrate group resilience.

Arya has received numerous honors, including the NASA Honors Award for the GRACE-FO mission, the Breakwell Award, and several fellowships such as the DAAD Scholarship, HEEP, and Outstanding Aerospace Graduate Excellence Fellowships during her undergraduate and graduate studies.

Life and space advice from astronaut Scott Kelly

Life and space advice from astronaut Scott Kelly Jeff Zehnder Wed, 11/20/2024 - 09:05

Jeff Zehnder

Scott Kelly is giving ��«��Ƶ aerospace students a insights on space and life as an astronaut.

A veteran of four space flights and a retired Navy pilot, Kelly has spent 520 days in space, including a nearly year-long mission to the International Space Station that included a special longitudinal study on the health effects of long-term spaceflight that compared Scott to his twin brother and fellow astronaut Mark Kelly, who served as a control group on Earth.

On Nov. 15, Scott Kelly spoke to a special gathering of students in the Aerospace Building at CU ��«��Ƶ.

What did you learn from the NASA twins study that was unexpected or unusual?

My telomeres on the space station got better compared to my brothers. Telomeres are the ends of our chromosomes, as we get older they get shorter and more frayed, kind of an indication of our physical age. The hypothesis was mine would get smaller compared to his because of the radiation, the stress, the microgravity, but the reality is mine got better compared to his.

At first we were confused about it, when your results are completely opposite of your hypothesis it’s a really stunning result. A few months after I got back NASA realized there was a telomeres experiment on the Japanese module of the space station, it was on these little worms, and their telomeres got better too. They learned later that radiation can excite your telomeres and cause them to get practically younger. But, after I was back they went back to normal.

The only lingering effects I have from my longer time in space is my vision. My brother needs reading glasses, but I can’t see without distance correction and that seems attributable to the time I spent in space.

What’s it like having a brother who was also an astronaut?

My brother applied the time before we got selected and he got rejected. So I think I pulled him across the finish line. If you consider he’s only flown in space for 50 days, versus my 500, that’s why he became a U.S. Senator, just to try to one up me.

What is your advice to someone who wants to be an astronaut?

It is a tough job to get, but that I’m standing here talking to you means it’s possible, because I wasn’t a great student when I was younger.

What I always tell people that want to have this kind of job, first you have to choose something that is technically qualifying. The second thing I say is choose the thing you want to study. Don’t become a fighter pilot in the Navy because I talked to you and that’s what I did. Do the thing you love because if you do stuff you like, you’ll do better at it, you’re going to enjoy your work and if you don’t get picked at least you’re doing something you value.

Generally the people who don’t have a military background or an operational background, let’s say you’re a scientist, the way they stand out from their peers is to do things, like hobbies, that are more operationally oriented, stuff that can put you under stress where there’s risk involved like mountaineering, scuba diving, learning to fly. Probably 100% of astronauts that didn’t have a kind of operational background had something else in their lives beyond their work to show they can perform well in these kind of stressful team oriented environments.

What inspired you to become an astronaut?

My first year of college I couldn’t pay attention. I didn’t know how to study. I never really did well, but I stumbled into the book store and saw The Right Stuff on the shelf and I read it and was like, I feel like I can relate to these guys, that I had very much in common with them with one exception: that I was a bad student. If I can fix this, maybe I can graduate from college someday with an engineering degree. If I can learn how to study and pay attention, maybe I can get a commission in the United States Navy and learn how to fly airplanes.

If you think an 18 year old kid reads a book and decides to become an astronaut is a giant leap, really in retrospect, it was a bunch of small, sometimes hard, but small manageable steps. One just built upon the other.

I used the book The Right Stuff almost like a recipe or cookbook, I kind of said I’m going to do what these guys did, it worked for them. It turned out it worked for me.

As technology progresses, do you believe it will become possible for the average person to go to space?

Spaceflight will have all different kinds of experiences. William Shatner going up in a suborbital Blue Origin at 90 years old, people are very capable of doing that.

Living on the space station for a week is a different thing. There’s a lot of things that are very uncomfortable about it. Between the fluid shifts, trying to sleep, using the restroom, eating, just functioning in that environment, it’s not for everyone.

What did you miss while in space and what do you miss now that you’re back?

I missed my wife. Mostly you miss people and the weather. You can’t step outside and get any fresh air, the air there is generally pretty stale.

Now what do I miss? The people that I worked with. I miss working at NASA. It was one of the greatest places to work in my career. I don’t mean riding the rocket or floating around in zero gravity or looking out at the Earth. What I mean is doing something that is really complicated, challenging, hard, and something that if you mess it up, can have really significant consequences, from losing your life to messing up someone’s life work of their science.

How does the spacewalk training in the neutral buoyancy pool at Johnson Space Center differ from actual space walks?

There are a lot of differences. You’re not in zero gravity. In the pool if you turn upside down, you’re not floating, your shoulders are basically resting on the bearings of the suit. Gravity still affects you.

The pool makes it easier to slow down if you’re moving, but it makes it harder to get moving. Whereas in space it’s the complete opposite because you have all this mass.

I would say the pool is probably physically harder, but what makes a spacewalk in space more challenging is the day is so long. The emotional aspect also makes it very draining. In the pool if you mess up, they just float you up to the surface. In the space station if you can’t get yourself back in the hatch, it’s a serious problem.

How did being in space for so long change your perspective about our planet?

There’s so much you learn about managing resources, conservation. You’re on the space station, and we use energy from the sun for electricity, we have to recycle our water, our ability to get garbage off the space station is very limited. Just living there you’re kind of forced to live with this resource management, recycling mindset.

Then when you look out the window you see how fragile our planet looks. One of the first few days on my first mission I said to one of my crewmates, “What’s that film over the surface?” He said, “That’s the atmosphere.” It looked like a contact lens over somebody’s eye, so thin and fragile.

Life in space from a CU ��«��Ƶ alumna who has been there

You don’t see political borders, at least during the daytime. It gives you a sense that we’re all floating through space on our big spaceship: planet Earth, and we need to take care of those resources very similar to how we had to deal with it on the space station.

When are we going to Mars?

I hope it happens in my lifetime. I think it could. The rocket science is pretty much figured out. I’ll quote my brother from years ago, “Going to Mars is not about rocket science, it’s about political science,” which is good, because he’s a politician, maybe he’ll help with that.

What was it like servicing the Hubble Space Telescope?

Seeing Hubble is cool.

It’s like the size of a school bus and you always generally see the side of it in pictures that looks really shiny and nice looking. The sun pointing side is always away from you. When you see the other side, it’s burned to a crisp. One side is all nice and shiny and that’s the side that’s facing the Earth, and the other side is burnt up and has holes in it like the space station does.

Just to realize this thing is seeing practically to the beginning of time is pretty cool. The fact that it’s still doing incredible science is pretty amazing. Hopefully Jared Isaacman is going to go up there and re-boost it someday. We’ll see.

Four aerospace PhD students earn NASA Fellowships Jeff Zehnder Mon, 11/11/2024 - 08:50

Jeff Zehnder

Four ��«��Ƶ aerospace graduate students have been named 2024 Future Investigators in NASA Earth and Space Science and Technology (FINESST).

Domenique Freund, Austin Smith, Gary Sutliff, and Hai-shuo Wang have each earned the grants, which provide up to $50,000 annually for three years to cover tuition, expenses, and student-designed research projects.

FINESST proposals must address goals relevant to NASA's science mission directorate divisions -- heliophysics, earth science, planetary science, or astrophysics.

Find out more about each of our awardees and their research below:

Domenique Freund

2nd Year PhD Student

Advisors: Lauren Blum and Zoltan Sternovsky
Lab: Laboratory for Atmospheric and Space Physics

My research focuses on the dynamics of energetic particle populations within the magnetospheres of Earth and Jupiter. Specifically, it aims to investigate particle losses through atmospheric precipitation, analyzing spatial and temporal variations on both planets. On Earth, I primarily examine relativistic electrons and their role in rapid depletion events. In contrast, my work on Jupiter covers electrons, protons, and heavier ions, addressing a broad understanding of particle dynamics. Understanding these variations requires analyzing magnetic field strengths and the influence of factors such as solar storms, the geomagnetic state, and Jupiter’s moons. By comparing precipitation patterns and overall energy input into the atmospheres of Earth and Jupiter, this research helps to not only understand atmospheric dynamics but also uncovers similarities and differences between different magnetospheres.

Austin Smith

2nd Year PhD Student

Advisor: Zoltan Sternovsky
Lab: Institute for Modeling Plasma, Atmospheres, and Cosmic Dust (IMPACT)

My research aims to further our understanding of dust populations in the solar system using spacecraft (SC) instrumentation. As dust particles impact SC with high velocities, they ionize and their constituents expand outward in a plasma plume that is not fully characterized. This work is focused on improving the mass resolution and sensitivity of time-of-flight mass spectrometers (dust analyzers) by designing ion optics that mitigate resolution-limiting plasma effects. Additionally, research into other performance limiting effects will be pursued and characterized in order to mitigate limitations on future dust analyzer instruments.

Gary Sutliff

4th Year Phd Student

Advisor: Xinzhao Chu
Lab: Chu Research Group

My research focuses on developing new tools for studying the upper atmosphere, near-space environment, and coupling between the thermosphere and ionosphere. The research grant focuses on the development of a new calcium and calcium ion Doppler lidar system, simulating calcium ion spectroscopy and the performance of the new lidar system, and developing data processing techniques to extend the range of Doppler lidars. The proposed system is expected to allow for measuring neutral temperatures and winds to over 200 km and ion temperature and winds to over 300 km, and observe the energy coupling between them. Additionally, it is theorized that one of the formation mechanisms of the natural metal layers in the thermosphere is due to the recombination of metal ions, and this system could lead to direct observations of that process.

Hai-shuo Wang

3rd year PhD student

Advisor: Dan Scheeres
Lab: Celestial Spaceflight Mechanics Lab (CSML)

My research focuses on the upcoming close encounter of the asteroid (99942) Apophis with Earth in 2029, when Apophis will pass closer than geostationary satellites. The strong tidal forces exerted by Earth could alter the asteroid’s shape, particularly as radar observations suggest it is likely a contact binary with a loosely bound structure compared to a monolithic body. To explore this, I aim to simulate the potential shape changes using high-fidelity contact dynamics models.

Captain William H. DuBois Graduate Assistantship

Recipient: Angela Wang, 1st Year PhD Student
Advisor: Jade Morton

Angela Wang's research is centered on the receiver signal processing part of remote sensing. With Prof. Jade Morton, Wang is working on processing signals of opportunity from low earth orbiting weather satellites to study ionospheric effects. In the years to come, she hopes to extend this work to more satellites and to study the troposphere as well.

Capt. William "Pyro" DuBois (AeroEngr BS'08) attended CU ��«��Ƶ aerospace on an Air Force Scholarship. Following graduation, he completed F-16 training and was twice named the top fighter pilot in his class. He served in the 77th Fighter Squadron, and on Dec 1, 2014, his wingman’s F-16 developed mechanical issues. True to his character and leadership, Will was escorting his wingman safely back to base, when his own jet went down.

"I feel humbled to receive an award honoring Captain William Dubois. He was a person who seemed to live life to the fullest and it motivates me to do so here at CU ��«��Ƶ both in and out of school. The assistantship's funding allows me to explore research topics of my interest for this year. Furthermore, it has given me extra flexibility to explore Colorado and my hobbies. I am so thankful for the assistantship and I will continue to make it worthwhile." - Wang
