Rydell Stottlemyer holds onto a payload, a box covered with aluminized mylar and filled with sensors, as it鈥檚 being connected to a huge weather balloon. The recent graduate of the University of Northern Colorado Physics and Astronomy program developed the payload with her fellow graduate Brian Smith.

Filled with nervousness and excitement, this is the moment she and Smith have been waiting for all semester as the culmination of their research project. Five, four, three, two, one, 鈥� lift-off! 鈥� she releases their payload as the balloon is launched into the atmosphere; they watch in awe, in anticipation of the data recorded during flight.

This was the scene in early April at Eaton Middle School where a number of balloon payloads were released. Their payload measured pressure, temperature, movement and time data as it made its 14-mile journey into the atmosphere, before the balloon eventually popped, and the payload slowly parachuted back to the surface.

鈥淚t was a wonderful learning experience, I definitely learned a lot and am happy I got the opportunity to take part in it,鈥� said Smith. 鈥淚t consumed me at one point, but out of passion, not out of necessity.鈥�

Lift off! The balloon rises with five payloads attached to it. It ascended to 14 miles in the atmosphere, which is about 10 miles higher than where airplanes reach altitude.

Smith and Stottlemyer 3D-printed and assembled two sensor housings to test the ability of the material, as well as different types of glues, to maintain internal pressure and temperature during the ascent. Many balloon experiments require that the pressure and temperature remain relatively constant. Their results will inform the design of future payloads.

鈥淭he Physics and Astronomy Department at 甜心视频app is so tight-knit, and they鈥檙e so supportive of everything that we do, and their priority is definitely the students and they want us to succeed in whatever we do,鈥� said Stottlemyer. 鈥淚f you鈥檙e curious about something, they鈥檙e willing to share that knowledge with you, it鈥檚 awesome!鈥�

This work was part of the Colorado Space Grant Consortium鈥檚 DemoSat Program, which provides students with frequent, low-cost access to creating, launching and analyzing data from balloon payloads. 甜心视频app is one of 21 institutions in the consortium and receives $25,000 a year to fund these types of projects as well as compensate the students who work on them.

鈥淧articipation in DemoSat allows students to become their own scientists, to build confidence, and to work as a team. Most of all, having this experience better prepares them for life beyond 甜心视频app,鈥� said Assistant Professor Matthew Semak of 甜心视频app鈥檚 Physics and Astronomy department.
