On the morning of Friday, August 15 four physics students, Kassie Surma 鈥15, Rachel Newman 鈥17, Maggie Singerhouse 鈥17, Emily Anderson 鈥17 and their professors, Erick Agrimson and Kaye Smith, ventured out to launch a high altitude balloon.

For Surma and Smith, involvement with ballooning came about as a component of their Summer Scholars research on technology in relation to data acquisition. 鈥淥ur project for the summer was to work with different programming technology. One day I was working with temperature sensors to get them working with the Arduino [a basic programmer] and I got it to work鈥鈥檝e been on the team since.鈥

Newman got involved after Jolene Johnson Armstrong, assistant professor of physics, mentioned Agrimson鈥檚 work with high altitude balloons. Shortly after reaching out to him, Newman regularly began attending flights and is now working with Agrimson on research regarding stratospheric balloons as a Clare Booth Luce scholar.

Singerhouse and Anderson were drawn to the project when their friends invited them to come along on a flight.

Prior to the launch, the students completed a pre鈥揻light checklist, which included making a prediction of the balloon鈥檚 landing. This required students to input the balloon鈥檚 take鈥搊ff time and location into a software program that estimates the time and location of its landing.

Unable to launch within eighty miles of the Minneapolis鈥揝t. Paul International Airport due to flight restrictions, the group headed to their launch site in St. Peter, Minn.

Upon arrival, the set鈥搖p went on without a hitch. Once lines, cables and wires were untangled, sensors were checked, batteries were installed and the camera was turned on, the boxes holding data鈥揷ollecting technology were sealed. After inflating the balloon, the entire apparatus was assembled and at approximately 10:50 a.m., the balloon was officially in flight.

Using a GPS device, the balloon鈥檚 location was consistently monitored throughout the duration of the flight. Other variables such as altitude, latitude, longitude, temperature, pressure and radiation (counts per minute) were also tracked using various programming technologies, such as the Arduino used by Surma.

After reaching a height of nearly 96,000 feet and traveling nearly 80 miles, the balloon began its descent and landed near a cornfield shortly before 1 p.m.

鈥淭he flights themselves are actually the best part鈥e learn from it every time,鈥 Singerhouse explains, on her favorite part of the overall flight experience.

For Kaye Smith, assistant professor of physics, math and engineering, the most exciting part of the day鈥檚 events was the balloon鈥檚 convenient landing next to the side of the road. 鈥淚t couldn鈥檛 have gone much better, really. The flight was excellent.鈥

Erick Agrimson, assistant professor of physics agrees. 鈥淭his couldn鈥檛 have been a better flight date. Launch location was beautiful. The landing was probably the second easiest I鈥檝e ever come across.鈥
