Want to learn how? Simply, sign up for text message flight notifications and Pegasus II will text your phone when it begins its ascent. You can then view live video and telemetry at the research team’s website, and you can download the mobile applications to your phone by searching for “Pegasus Mission.” Or, follow on Twitter @PegasusMission.
Through the first Pegasus Mission experiment, the team was able to show real-time Microsoft Azure IoT capabilities including Azure IoT services such as Azure Stream Analytics. The unique experiment in High Altitude Science featured Pegasus 1, a meteorological balloon that carried a payload packed with sensors, radios and video to an altitude of 100,000 feet. Similar to Pegasus II, the public was able to interface with the craft during flight through a website or mobile apps. Those who participated discovered that they could receive atmospheric information and also communicate with the craft during flight and in real-time.
