Youth Slam Science Summer Camp Launches Weather Balloons Wednesday (July 29, 2009)

Clark School Aerospace Engineering Students to Assist

WHAT: As part of the National Federation of the Blind Youth Slam, A. James Clark School of Engineering students will assist the blind high school students on campus with a weather balloon launch (see photos left and below). The students will build, test, and fly a small payload that measures temperature and pressure as it rises high in the atmosphere. The payload includes a GPS unit and a radio that will send data back to the ground during the entire hour-long flight.

The payloads will be lifted up to "near-space" by the balloon that is somewhere in size between a large party balloon and a small weather balloon. Around 30,000 or 40,000 ft in altitude, the balloon will burst and the payloads will descend on parachutes to the ground somewhere on the Eastern Shore of Maryland.

"This is like a small microcosm of what NASA goes through to launch a payload but considerably less expensive!" says Terry Teays, assistant director of the Maryland Space Grant Consortium and one of the instructors for this project.

Once the balloons are released, data radioed down from the payloads will be received at a ground station and automatically translated into audio so the students can listen to their data as the balloons ascend. This is a first-time attempt of that particular task.

WHO: The balloon payload group of the Clark School Space Systems Lab is helping to conduct one part of a week-long summer science academy for blind high school students from all across the country, sponsored by the National Federation of the Blind (NFB). There are five teams of three students and a mentor.

WHEN: Wednesday, July 29, 2009, *weather-permitting*

The tentative schedule for the morning is as follows: 8 a.m. -- instructors will start inflating balloons in the Kim Building Rotunda and carefully measure and adjust lift of each
8:30 a.m. -- students will arrive, check out their payloads, and tie them on to the balloons
9 a.m. -- final weather check; communicate with College Park Airport; go - no go decision
9:30 a.m. -- all teams bring their balloons and payloads out the double doors and gather in the middle of the Kim Plaza
10 a.m. -- final communications check with ground station, countdown and simultaneous release of all 5 balloons
After the release -- audio monitoring of data downlinked from payloads to ground station

If the weather and winds aloft cooperate, all five balloons will be released simultaneously.
