Newswise — Tulane University engineering students’ innovative idea for a flower-shaped, solar-powered space ferry won the top prize in NASA’s BIG Idea Challenge, a national contest to design better ways to assemble spacecraft in space.
Five finalist teams from around the country presented concepts for next-generation spacecraft to top scientists at the NASA Langley Research Center in Hampton, Virginia, on Feb. 16. The challenge is part of NASA’s efforts to rapidly develop game-changing technologies for future space missions, including transit to deep-space locations such as Mars.
The winning team members get paid internships at NASA this summer.
“I’m extremely proud of our students who put in so much independent effort towards making their project absolutely excellent,” said Tim Schuler, the team’s faculty adviser and senior professor of practice in engineering physics. “They were up against very stiff competition from other extremely talented students and programs, but they were confident in their design and gave a fantastic presentation. I’m grateful that the judges considered their design as impressive as I did.”
Dubbed “The Sunflower,” Tulane’s winning concept calls for stackable hexagon-shaped modules that unfold like origami from a rocket bay at low-Earth orbit. The identical pieces connect together via magnetic locks to assemble themselves into a one large array of solar powered ion engines that can ferry cargo into orbit around the moon. They explain their concept in this video.
“The Tulane team did an incredible job of designing a spacecraft that is both revolutionary and realistic,” said graduate student and team founder John Robertson. “We blended existing technologies with an innovative design to propose a spacecraft that we are very proud of.”
Tulane’s team also includes undergraduates Otto Lyon, Ethan Gasta, Matthew Gorban, Afsheen Sajjadi, Maxwell Woody and Ben Lewson.
“It was a great validation of all of the work we have been doing for the past six months,” said Lyon, team leader and a senior majoring in physics and architecture. “It’s a tremendous feeling to know that our design will have a place in the body of research in the future of in-space spacecraft assembly.”
Lyon said the win was even more remarkable because not a single member of the team is an aerospace engineer. Team members are pursuing degrees in biomedical engineering, engineering physics, economics and other disciplines.
“With no background in aerospace, we came up with this really modular idea that was more out of the box,” he said, explaining that he drew upon his background in architecture to help design the symmetry and movement of the assembly system. “I think they chose us because we did something crazy and different.”
The team’s interdisciplinarity was key to the win, said Matthew Escarra, assistant professor in engineering physics who advised members of the team. “The other teams represented traditional aerospace engineering at the top programs in the country,” Escarra said. “Our hybrid, cross-disciplinary team embodied the Tulane vision of finding innovative solutions from totally different and unique perspectives. It was unlike anything the judges had seen before. This is what won the judges over, and it is an important validation of the unique model at Tulane University’s School of Science and Engineering.”
