On September 4, 2015, NASA Glenn’s Rocket University team launched a balloon in New Mexico to demonstrate the controlled descent of a high altitude balloon payload to a predetermined landing site. The payload elevated to 120,000 feet and then disconnected from the balloon and was guided to the landing site by a paragliding parachute. The ANGEL experiment demonstrated how the Airborne Systems, Inc. Guided Precision Aerial Delivery System (GPADS) can benefit planetary science balloon missions through a risk-reduction flight test for high altitude balloon operations allowing for faster and cheaper recovery. Additionally, the impact forces experienced on landing are reduced with GPADS versus conventional parachutes. ANGEL shows a greater range of space science able to be performed with more sensitive equipment, as payload survivability is increased due to the system’s unique ability to perform a flared, into-the-wind landing. The ANGEL System is comprised of a drogue chute, ram-air canopy, and gondola, and will be taken to float altitude on the CSBF host vehicle and released. The integrated system will then cleanly separate and will land within the targeted impact zone. Landing loads, GPS and flight attitude and telemetry will be collected. ANGEL is an important first step towards maturing steerable paraglider technology and improving recoverability for high altitude balloon missions. (sound- natural wind only)
