What is Pegasus II?

• An Experiment

• An Experience

• An Adventure

Fly a high altitude balloon equipped with a huge sensor package and video traveling to 100,000 feet in the upper atmosphere. Stream the telemetry and video live to large number of users using a Web site and Phone apps to provide a real-time experience to people from the remote, hostile, and ultimately beautiful environment of the upper atmosphere. Control the UAV’s flight operations from the ground. Allow users to send information onboard the inflight craft. Contribute to High Altitude Science and STEM research by achieving something has not been done before and previously not thought possible. Make it a participatory event for users. Experiment with new concepts and technologies at large scale and make real-time IOT both a reality and experiential. Embrace risk and take calculated chances to achieve remarkable goals. Be innovative, creative, and resourceful in bridging across STEM fields. Inspire a few people along the journey.
