Does NASA really need to reinvent the wheel? When it comes to navigating the moon’s surface, yes. It turns out that UVM is assisting the effort with cutting edge research from students who’ve been specially selected as participants in the highly competitive eXploration Systems and Habitation (X-Hab) 2018 Academic Innovation Challenge. UVM is one of just 11 university teams NASA chose to design systems and technologies that enhance the agency’s ability to explore deep space.
Since early September 2017, engineering seniors Liz Barrett, Thomas Durivage, Liam McAuliffe, Adam Potasiewicz, Catherine Simpson and junior Boxiong Yang from the College of Engineering and Mathematical Sciences (CEMS) have been working to develop a single-wheel test bed that would aid NASA’s Resource Prospector mission, which aims to be the first robotic rover to search for water ice trapped in the lunar soil. The team is designing a rover wheel testing device compatible with NASA’s reduced gravity aircraft that allows wheel testing under simulated lunar gravity.
“This is by far the biggest project I’ve done,” says Potasiewicz of the year-long effort, which is also a senior engineering capstone project. “It’s way different from internships in the past, in a way different environment, and it’s helping me refine what I want to do in the future.”
That different environment includes NASA’s Glenn Research Center in Cleveland, Ohio, where, in November, the team presented the design concept “Reduced Gravity Airborne Mobility Testbed” that is now being built. The students are being advised by engineering faculty professors Darren Hitt (Mechanical Engineering) and Mandar Dewoolkar (Civil and Environmental Engineering), along with Ryan McDevitt, PhD from Benchmark Space Systems, Inc. in South Burlington (a UVM adjunct who is also serving as an industrial mentor). The students have not only contributed to NASA research, but also reaped tremendous knowledge about practical applications. After the NASA Glenn visit, Durivage and the team received feedback that gave them more perspective. “I had a preconceived idea of what it means to design something, so the NASA visit was invaluable,” says Durivage, adding that the biggest challenge so far has been balancing the X-Hab project with classes. “For all intents and purposes, we are students, and these are real-world problems and criteria for NASA and the world.”
“After our call for proposal, UVM had the most promising idea,” says Paul Banicevic, a systems engineer at NASA Ames who is part of the Resource Prospector Team and the lead NASA mentor for the UVM X-Hab team. “And the process pivoted exactly how I hoped it would, growing from there being kind of new, and not really understanding, to really owning and providing great design. Sure, we had the idea of putting it on a plane, but the UVM students put their own custom stamp on it. The insight and the enthusiasm has carried over to my side, as well.”
The X-Hab project is an outstanding opportunity for these UVM undergraduate students and is just one example of the opportunities generated by the Vermont Space Grant Consortium (VTSGC), founded in 1992 as a statewide initiative and now overseen by Hitt, a professor of mechanical engineering in CEMS. “I’ve made it a priority to expand undergraduate opportunities in aerospace science and engineering,” says Hitt. Design competitions such as the X-Hab, weeklong summer workshops and NASA internships are among the ways that UVM students are finding a foot in the door at leading companies including Boeing, Blue Origin, the United Launch Alliance (ULA) and even SpaceX, which just sent a Tesla into space. “A number of our students have gone into aerospace engineering at high profile companies,” says Hitt. The work also reflects the interdisciplinary collaboration that happens across CEMS and UVM and is critical to the aerospace industry, adds Hitt.
“The teams really have to work and integrate together well, with very strong, meaningful communications with NASA mentors,” he says. “The X-Hab (project) has very exact design specifications, and NASA has made some changes along the way, causing the students to quickly turn around and find a new design—it’s amazing; they are so dedicated and hard-working.”
Such a process has turned frustrations into tremendous rewards, report both the students and their mentors. Learning the agility to respond immediately, graciously and accurately to a new design demand or constraints is an invaluable lifelong skill, as is learning professional coping mechanisms to avoid becoming overwhelmed by expectations.
“It's a unique opportunity in that it is truly going to pay off in their careers,” says Hitt of the experience enjoyed by the students in the X-Hab 2018 Academic Innovation Challenge.
