Many sudden changes had to be made if the team was to be ready for a planned June launch.
Kalaygian drove to campus from his home in Milford, Delaware, to pick up equipment and materials Maruca thought he might need to continue the work. He set up a workshop in his basement and — using Zoom and other communications — the team worked together virtually, “with me being the hands,” he said.
No one wanted to quit.
“None of us was OK with that,” Kalaygian said. “We all put in so much work. It was push forward, no matter what.”
Ultimately, COVID forced the cancellation of the 2020 launch, and the torch was passed to the 2021 team, led by Dagney, who designed the software to run everything.
The extra year gave the team opportunities to refine their designs and by June 2021, Maruca’s team converged near Wallops Island to watch the rocket shoot into the sky with their Langmuir probe aboard.
Lessons learned produced further refinements for the 2022 team, led by Jeffrey Neumann, who had graduated a few weeks before the June launch with a degree in mechanical engineering.
“It’s been great to be able to build on progress from prior years,” Maruca said. “I’ve been very insistent — I’m trying to avoid the word ‘nagging’ — about documentation.”
Good recordkeeping is a great help to subsequent teams.
“It is very helpful,” Neumann said. “We were able to refer back to documentation, particularly in regard to our analog board, and that was very important for our development work.”
The team was able to collect relevant data in both launches, which is not a given.
“To have successful measurement on the first go is very rare,” Maruca said.
And progress has been steady.
“I am so proud of these students,” he said. “They have done a tremendous job.”
UD’s RockSat-C team now has a new headquarters in the Patrick T. Harker Interdisciplinary Science and Engineering (ISE) Laboratory, where Maruca is establishing the Delaware Space Observation Center (DSpOC), a collaboration of UD and Delaware State University that was announced in 2022. Dagney is now the DSpOC lab manager and Maruca is leading the research component, which includes a high-performance computer cluster for analyzing large data sets.
The team changes each year, with some students graduating, some moving on to other kinds of research and some joining the effort for the first time. Some participate in the RockOn workshop, which gives students experience building a launchable payload, including a computer board, experiment materials, programming and mechanical integration — all in preparation for a RockSat launch the following year.
Senior Dax Moraes and sophomore Isaac Chandler participated in RockOn in 2022. Moraes then led UD’s RockSat team.
The experience helps students work through challenges, disagreements, complications, unexpected delays and obstacles — real-life stuff, Maruca said.
“In research in general, there’s not always agreement on the best way to do things,” Maruca said. “It’s not always obvious. And if you’re going to work at an engineering company, you’ll be in a meeting and present an idea and someone will say, ‘What about doing it this way?’ Who is right? Who has the better way? You have to explain your reasoning. And your boss may not be an engineer.”
In addition, all team members learn a lot about working in a high-level system that requires careful planning and precision. They learn the nomenclature and design review structure used for many missions in NASA, said Maruca, who is the principal investigator of the Solar Wind Experiment on NASA’s Wind spacecraft, which aims to characterize the particles in solar wind plasma.
“This is quite literally, NASA-level stuff that students are able to participate in,” Neumann said. “It’s a cool opportunity, but along with that comes the NASA-type deadlines. The deadlines always seem far away, but then you always barely make it in time. Deadlines are very, very important for an aerospace-grade mission like this.”
This week, they hope all systems are “go.”
“It’s quite cool seeing the rocket launch,” Neumann said. “It’s nothing like the space shuttle or the SpaceX Falcon 9. It’s basically a missile, moving at 20Gs — very fast. At the same time, the moment it starts lifting off, our payload starts collecting data. So in addition to seeing this massive object launch, our payload turns on and starts observing data.”
About the researcher
Bennett Maruca is an assistant professor of physics and astronomy at the University of Delaware. (He will advance to associate professor officially on Sept.ember 1.) His research focuses on space physics, plasma physics, turbulence theory and computational physics.
He is an associate director of the Delaware Space Grant Consortium, coordinating student experimental activities across the consortium, which includes UD, Delaware State University, Wilmington University, Swarthmore College, Villanova University and Delaware Technical Community College.
Before joining UD’s faculty in 2016, Maruca was a postdoctoral fellow at the University of California, Berkeley. He earned his doctorate at Harvard University, where he was advised by Justin Kasper.
