A ring of fire eclipse will light up the sky on
Saturday, Oct. 14, 2023, and a team from South Dakota Mines (SDM) will be
working to capture it on camera.
Jason Ash, Ph.D., an associate professor of
mechanical engineering at SDM, will be taking students from the university and
area high schools to Farmington, N.M., which is within the path of the eclipse,
to capture it on video in real-time from a weather balloon. The work is all
part of the Nationwide Eclipse Ballooning Project, an initiative spearheaded by
Montana State University, incorporating 80 universities/institutions nationwide.
Teams will launch video equipment to record the eclipse on Oct. 14 and again
during the total eclipse on April 8, 2024.
The eclipse will be live-streamed in real time, says
Peggy Norris, Ph.D., who is retired from the Sanford Underground Research
Facility and is volunteering with the project. Norris says the balloon will
serve two purposes during its launch: collecting atmospheric data and
broadcasting the eclipse in real time.
Ash says it takes upwards of two hours for the balloon
to rise to its expected height, around 100,000 feet above the Earth's surface. The
balloon will collect and send data using an RFD link during its flight. Once
the balloon returns to Earth, the team from SDM will retrieve the payload
instrumentation to gather additional data that will be collectively pooled by
all teams for broader research and public release.
Ash explains that the university is within a pod of
Midwestern universities, with SDM as the lead for the collaborators within
South Dakota and Wyoming and the University of Minnesota as the overall pod
lead. Funding for the overall project comes from the NASA Science Mission
Directorate and National Space Grant Foundation with additional support from
the NASA South Dakota Space Grant Consortium.
With the team arriving in Farmington on Thursday,
Ash says, "We'll do some additional outreach-related activities and ensure
the payload instrumentation is ready to go and prepared so that, Saturday
morning, we can launch those on time." Ash adds that the group will be
split into a launch team, a ground station team to do the tracking and a
recovery team.
This project has involved students at SDM and
various West River and western Wyoming high schools, including Spearfish,
Lakota Tech and Newcastle, and a teacher from Southwest Middle School.
South Dakota Mines students are capitalizing on this
project to help inspire future research. This semester, Evie Chang, a senior
electrical engineering major, joined the project. She wanted to participate
because she was interested in helping with the radio frequency from the balloon
and says there are plenty of opportunities to tie the work from the ballooning
project into what she is learning in the classroom.
"I think there are opportunities for me to tie
this into my senior design project or at least get more experience working with
radio frequencies," Chang says. "Dr. Ash talked to me about
increasing the signal-to-noise ratio for the cameras, so I think we can get a
better range and just a better signal in general, and that would be my
potential future project."
For those in South Dakota who want to view Saturday's
eclipse, Norris says the eclipse will be at about 60% within the area.
