3. 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.
