A&M Gets ‘Spaced Out’
AAMU Makes First-Ever Balloon Launch!
Huntsville, Ala. —- Two Alabama A&M University engineering Senior Design classes recently launched BalloonSat from the National Space Science and Technology Center (NSSTC) site in Huntsville, Ala.
The historic balloon launch, which took the AAMU name and logo to the outer edges of space, was made possible by a funded proposal written by AAMU electrical engineer Koy Cook to the Alabama Space Grant Consortium (ASGC). Dr. Cook also secured other funding for the project. The technical assistance the two senior design teams needed for their respective projects was provided by Dr. John Piccirillo of the Huntsville-based Radiance Technologies.
AAMU BalloonSat (Senior Design Teams ‘E-Boys’ and ‘ACES’) was launched about 10:34 a.m. Saturday, April 4, from the NSSTC site, and it was allowed “to go to burst,” after achieving an altitude greater than 89,000 feet, according to John Piccirillo, an avid senior design volunteer at AAMU and UAHuntsville.
The balloon launch endeavor was “the first ever by an AAMU team,” noted Stoney Massey, an AAMU assistant professor of electrical engineering, who witnessed the launching of the AAMU BalloonSat. Massey lauded the support of ASGC as a contributing factor to the success of the AAMU teams.
The AAMU payloads were recovered about 100 miles east of Huntsville, reported Piccirillo, only about two miles from a payload from a balloon launched by a team at UAHuntsville.
AAMU BalloonSat carried the payloads of the two distinct senior design teams. The Team E-Boys’ project measured the payload spin rate with a MEMS gyroscope, the ambient light intensity with a light-to-frequency sensor, and internal and external temperature sensors. A solar panel atop the payload was used in parallel with battery power to provide power for the electronics. Both still and video cameras were used to collect imagery.
Piccirillo says the payload of the second AAMU group, Team ACES, measured the payload tilt as it swings below the balloon with a MEMS accelerometer; the speed-of-sound with a small sonar sensor; and atmospheric pressure and internal and external temperature. A solar panel atop the payload was used in parallel with battery power to provide power for the electronics. Still and video cameras were used to collect imagery.
“We are excited about the balloon launch and what our students have accomplished, said Dr. V. Trent Montgomery, dean of the School of Engineering and Technology at AAMU. “We are producing quality students who can interact and solve today’s problems.”
Montgomery called the launch “a tremendous growth experience” that will re-enforce the pride the students have in their education and capabilities. One of the goals of the projects was to test the efficiency of different solar cells as power sources for experiments. During the flight, the balloon traveled at speeds in excess of 160 miles per hour.
Tracking of the payloads was performed by committed balloon trackers Jason Winningham, Shane Wilson and Bill Brown.
