HASP

The High Altitude Student Platform (HASP) is designed to carry up to twelve student payloads to an altitude of about 36 kilometers with flight durations of 15 to 20 hours using a small volume, zero pressure balloon.  It is anticipated that the payloads carried by HASP will be designed and built by students and will be used to flight-test compact satellites or prototypes and to fly other small experiments.

HASP includes a standard mechanical, power and communication interface for the student payload, based upon a flight tested design.  This simplifies integration, allows the student payloads to be fully exercised, and minimizes platform development / operation costs. In addition, HASP is lightweight and has simple mission requirements, thus providing maximum flexibility in the launch schedule.
