Project HALO - Sky Launch 1 Launch Report


SL-1 Liftoff

HAL5 made amateur rocketry history on Sunday, May 11, 1997.  At 8:25 AM EDT, HAL5's Project HALO team performed the first amateur rockoon mission when it successfully launched its Sky Launch 1 rocket from a high altitude balloon.  HAL5 also made hybrid rocketry history as well, becoming the first organization to launch a hybrid rocket from a high altitude.  Based on an estimated rocket apogee between 30 and 36 nautical miles, HAL5 can now claim the world record for highest altitude achieved to date by an amateur rocket -- and by a hybrid rocket of any kind.

Purpose of Project HALO

The purpose of Project HALO is to make access to space more affordable for students, amateurs, experimenters, and researchers.  It is combination technical and educational program.  The program is divided into several phases.  All phases have opportunities for student involvement at all grade levels. See the Project HALO Home Page for more details.


Goals of HALO Sky Launch 1

Project HALO Sky Launch 1 marks the completion milestone for Project HALO Phase 1, Proof of Concept.  As such, this successful launch was the final test for Project HALO to proceed onto Phase 2, Operational Rockoons, when we can start to launch student payloads.
