This blog features Dave Akerman’s High Altitude Ballooning missions, when he sends payloads into the stratosphere at up to 140,000 feet. The payloads include GPS receivers, flight computers and radio transmitters to relay co-ordinates and sensor data to the ground. Missions usually include still or video cameras. Last year Dave was the first to use a Raspberry Pi under a weather balloon, when it sent back live images throughout its flight. A future flight plans to emulate Felix Baumgartner’s jump, but miniaturized with a “Space Ted” jumping from the same altitude. The photograph above shows another balloon (which was launched at the same time) several thousand feet below.
