Shaftesbury High School student volunteers design, build, test, launch, and recover a scientific payload equipped with electronics and sensors attached to a high altitude balloon. • High altitude balloons (HABs, for short) used in SHARP are capable of reaching altitudes above • 120,000 feet (37 kilometers).
3,000 gram high altitude latex balloon zip tied and duct taped • Custom made parachute made of rip-stop nylon and dacron string fastened to fishing swivels • Modular foam board payload box, taped and hot glued
Composed of 3 Modules • Communications Module: radio, cut down circuit, battery pack • Science Module: Geiger-Muller counter, temp sensors, and experiments to test the effects of radiation exposure • Photo & Video Module: Canon PowerShot A1200 & GoPro HD video camera
After launching the balloon and payload we packed up and got ready for the chase. We stopped to watch it at 126,000 ft. in Gladstone. After 1.5 h in the air the balloon slowed its ascent. We grew impatient waiting for it to pop so we headed back to Winnipeg. Again the balloon started to rise, and suddenly all communications were lost! Cool Fact: Our principal who stayed behind at Gladstone actually saw the balloon explode!
SHARP 2 exploded at 126,634 ft. (38.6 km) and travelled over 100 km, reaching a maximum speed of 144 km/h until its recovery south of Gladstone, Manitoba after 3 hours and 44 minutes in the air.
