Mission Goals:
Multiple imaging systems with an active thermal system
Use Digipeat capability of the TNC
Sound at high altitude experiment
Very Low Friction Bearning Swivel Experiment
Video coming soon! Burst and high altitude were very dramatic!
Mission Statistics:
Primary APRS packet efficiency, 94.2% (180 out of 191 packets per hour received on the ground)
54.1 minutes to burst at 91,646.9 feet altitude, 28.1 minutes to reach the ground, total linear distance = 23.5 miles, maximum horizontal speed, maximum horizontal speed = 57 mph, maximum vertical speed = 99.1 mph down, 31 mph upward, Total payload = 10.7 pounds, Lift = 21.5 pounds, Free Lift = 10.8 pounds (we thought it would burst lower!)
