UND hosts North Dakota Space Grant’s 8th annual Near-Space Balloon Competition for scientific youth
The North Dakota Space Grant Consortium likes to keep things current for the kids.
Now in its eighth year of administering the Near-Space Balloon Competition (NSBC), coordinator Marissa Saad wanted a theme that was relevant to 2018.
“In the past we’ve had Mars-themed missions,” she said. “Last year, we focused on solar because of the eclipse.”
This year marks 60 since the inception of the National Aeronautics and Space Administration, better known as NASA. Saad found it a perfect way for middle and high school competitors to get creative.
The NSBC is a hands-on experiential learning program organized by Saad, fellow coordinator Caitlin Nolby and graduate student Denise Buckner in UND’s Space Studies program. Each year, schools around the state have students from grades 6 through 12 participate.
Their mission: create an experiment, create a payload that can test the experiment, then send that payload aboard a high-altitude balloon to the reaches of Earth’s atmosphere.
On Saturday, two high-capacity balloons launched from South Kiwanis Park in Grand Forks, each with six attachments in tow. Afterward, teams digitally tracked them from UND’s Robin Hall.
“These payloads get to around 100,000 feet,” Saad said. “That’s at least three times higher than a commercial airplane’s cruising altitude. At those heights, you start to see the blackness of space and the curvature of Earth.”
Images and video captured by student-crafted payloads never become less breathtaking.
Ten teams entered this year’s competition, a number Saad says is growing every year. To celebrate NASA’s 60th, Saad instructed them to craft an experiment that had something to do with the mission, goals and inspirations of NASA.
“They’ve designed biological experiments, technological – a lot of cameras, Raspberry Pis and Arduinos,” she said, referencing the mini-computers typically used in high-altitude ballooning ventures that run sensors and collect data. “Experiments are all across the board, which is awesome.”
Approximately 140 people—students, teachers and chaperones—converged on campus for Friday’s ‘integration night.’ Teams orally presented their experiments in Clifford’s second-floor lecture hall then traversed the tubes to Robin for a two-hour workshop session led by graduate students.
Buckner, a Space Studies graduate research assistant, has headed up workshop efforts for two years now. Thanks to the graduates, Friday’s activities ran according to plan.
“It’s a big effort, but thankfully we have a great team,” Buckner remarked. “Our group of graduates have been helping mentor these teams, write code for their sensors and creating our own payloads to accompany the launch.”
At the main workshop, each team had a table where judges evaluated their aptly decorated payloads and weighed them to ensure adherence to the two-pound limit. Once cameras and sensors received a final test, payloads were deemed ready for launch integration – tethering them with rope for eventual connection to the balloons. It also created an opportunity for judges to follow up with teams following their brief presentations.
Then groups broke out into varying sessions. Students got a closer look at the hardware necessary for launching a balloon nearly 20 miles into the sky; how they would be tracking their payloads the following morning; and software that could predict the balloon’s path using inputted variables and atmospheric conditions.
The staircase at Robin Hall also proved a fitting model for layering the atmosphere, demonstrating what the balloons would encounter on their ascent.
Through Buckner’s experience, it’s most rewarding to see students out in the field and seeing their work in action.
“When you have students come in that haven’t been exposed to this kind of research, and seeing how excited they get about what they’ve built and seeing it launch, it’s always great,” she said.
The NSBC is designed to be much more than a competition, as North Dakota Space Grant’s goal for education outreach is to teach young thinkers how to be scientists. They work with school faculty to teach team members how to write proposals, record results and write reports on their findings. Awards are decided after teams submit their final reports next month.
Given the range of ages able to compete, Saad says NSBC is about how they design and compose their proposed experiments as a team.
“They could launch a rock up to space,” she quipped. “It doesn’t have to be a complex experiment, as long as they support it with controls, variables, reasoning and a solid conclusion. We provide this platform to get their experiments to space, not to assess them strictly on content.”
North Dakota Space Grant also provides the experience of coming to UND as an all-inclusive excursion; they cover travel, lodging and accompanying expenses for those coming from communities as far as New Town and Bismarck. Space Grant also reimburses teams for up to $250 spent on constructing payloads. It’s all an effort to impact the youth perception of science.
“They’re at that critical age where you have to capture their interest in STEM,” Saad said. “We’re showing them the possibilities of careers, of going to college and showing them that science is fun!”
