PhD student Laura Shannon, alongside Professors Greg Rieker and Peter Hamlington of the Paul M. Rady Department of Mechanical Engineering are setting fires inside wind tunnels to gain a better understanding of how fire spreads across different terrain. The team says their findings could help keep communities safer in a world where climate-driven wildfire is becoming more common—and more dangerous.

A window underground: New sensors measure emissions from soil in real time Alexander Jame… Thu, 11/20/2025 - 14:40

Soil is comprised of an intricate network of bacteria and other microbes that humans depend on, but this complex environmental system is constantly shifting, making it difficult for scientists to measure. Associate Professor Gregory Whiting and his team of researchers are developing reliable, inexpensive and easy-to-deploy sensors that monitor soil in real time to help farmers optimize their use of fertilizers, reduce greenhouse gas emissions and save money in the process.

Go for launch!

The 12-foot-tall rocket roared off the pad, streaming higher and higher until it was barely more than a pinprick in the morning sky.

At 9:15 a.m. on Sunday, October 12, the �Թ�� of Colorado Boulder Sounding Rocket Lab (SRL) successfully launched a rocket to 90,000 ft. in altitude.

Designed and built by students in the club, the Mamba III rocket was a multiyear effort for SRL.

“Over 100 students worked on this project,” said Robert Umali, the team solids/composites lead and an aerospace sophomore. “Our test fire in March performed flawlessly. This rocket is built like a tank.”

Built From Scratch

Although off-the-shelf rocket plans are available online, the team elected to design theirs from the ground up, said Tyler Boim, team co-captain and an aerospace senior.

“Anything that we can make in-house we do. We fully made our avionics, composites, structures, and propellant. You understand each part and why it’s there. We’re not building Legos. You become a better engineer,” Boim said.

Putting the extra work into an independent design has also had career benefits for members like Nick Kieft, fellow team co-captain and an aerospace senior.

“It’s experience for industry. In internship interviews, most of what I talk about with companies is the team. I manufactured this, designed that, tested this,” Kieft said.

The successful launch in California’s Mojave Desert was a moment of exhilaration for all the team members, but only one portion of the day’s excitement, as the rocket body also contained sensors and cameras to track the flight and its landing.

Hitting Mach 3.36

“Mamba had a maximum Mach number of 3.36, equivalent to a velocity of 2,393 mph. Consistent communication of the rocket's flight computers throughout ascent and descent enabled us to determine a landing position and recover the vehicle. The final GPS coordinates were within 50 feet of the landing location,” Kieft said.

Getting to the finish line was not always easy. The team experienced significant setbacks in launches on the previous Mamba I, which suffered a nose cone failure, as well as Mamba II, which exploded midflight.

“Mamba III used the same principles of the original design, but was reworked to account for lessons learned. We spent an entire year recharacterizing the propellant. We overbuilt this rocket to guarantee there would be no failures,” Boim said.

Next Steps

With the successful launch, the team is moving on to a much bigger goal called Spaceshot. They are beginning work on a new rocket design that can reach at least 350,000 ft. in altitude and become only the second student rocketry organization in the world to cross the atmospheric boundary into space – internationally designated at 328,000 ft.

“There will be big infrastructure improvements. We’ll be developing it over the next year or two,” Boim said.

Although that launch will be after senior team members like Boim and Kieft graduate in May 2026, each team stands on the shoulders of earlier graduates, incorporating their design and education in the next iteration.

“I won’t necessarily be here for that launch, but a lot of the work you do leading up to it is just as valuable and rewarding,” Kieft said. “There’s smaller milestones along the way. SRL takes all the important first principles we learn in class to the next level.”

AISES student leader inspired at NASA internship

Redhorse with OPTIMISM, a full-scale twin of the Perseverance rover that is exploring Mars.

Shellene Redhorse took her passion for aerospace engineering beyond the classroom to NASA’s Jet Propulsion Laboratory (JPL) this past summer.

Redhorse, a fourth-year aerospace engineering student and president of CU Boulder’s chapter of Advancing Indigenous People in STEM (AISES), spent her internship at one of the world’s most renowned research centers.

Redhorse joined the Spacecraft Mechanical Engineering Division at JPL, where she worked on VenSAR, a Venus synthetic aperture radar that will launch aboard the European Space Agency’s EnVision mission in the early 2030s. The instrument, built in partnership with NASA, will map the planet’s surface and study its volcanic and geological activity.

“It’s incredible to be part of something that will orbit Venus one day,” Redhorse said. “Knowing that even a small piece of what I worked on will help us understand another planet is surreal.”

She worked with several teams that specialized in deployables, structures and thermal engineering giving her hands-on experience in spacecraft design and testing. She modeled test setups in CAD, worked with Nomex honeycomb tiles, conducted structural testing and even helped cycle thermal samples through high and low temperatures in a HALT chamber.

“I learned a ton about CAD and geometric dimensioning and tolerancing which was challenging but rewarding,” Redhorse said. “It’s one thing to design something on a screen, but it’s another to know that hardware you helped create will actually be manufactured and tested.”

While her internship was technical, it also had moments that brought wonder.

Redhorse toured the massive JPL campus located in Pasadena, California where legendary missions like the Mars rovers and Voyager spacecraft were born. One highlight was visiting the Mars Yard, where researchers tested rover replicas like OPTIMISM, a twin of Perseverance, and Scarecrow, a lighter model designed to mimic Martian gravity.

Another favorite moment was seeing one of the earliest color reconstructions of Mars, created by NASA engineers using data transmitted as numbers and colored in by hand.

“They only had bits of numbers and made a color-by-number image using crayons,” Redhorse said. “Seeing that creativity reminded me that science and engineering are human experiences.”

Representing Native excellence in STEM

As one of the few Native interns at JPL, Redhorse carried a sense of purpose throughout the experience. While the internship was a dream experience, Redhorse, who is Diné and Chickasaw, was excited to pave the way for more Native representation in science and engineering.

“There are few Natives, but we’re strong,” she said. “I met another intern from the Navajo Nation. It felt powerful to represent and be proud of who I am and where I come from.”

What brings me joy is supporting other Native students and learning about aerospace. I love sharing knowledge, lifting each other up and finding happiness in community.

After graduating, Redhorse is considering graduate school where she hopes to continue exploring aerospace, robotics or mechanical engineering. She’s been inspired by mentors who’ve shown her what’s possible. One of those is Aaron Yazzie, a Diné mechanical engineer at JPL, whose story originally motivated her to pursue aerospace.

Redhorse says one thing remains constant for her — determination to keep helping others along the way, especially Native students.

“Grab as many opportunities as you can, even if they feel outside your comfort zone, just go for it,” Redhorse said. “People are more supportive than you might think and there’s a strong community here at CU Engineering and the Campos Student Center to help you along the way.”

Mars Yard, a site on the JPL campus, is filled with Mars-like rocks and sediment simulating the planet's surface.
