Abstract
An atmospheric balloon descent system includes a system housing having a drogue chamber containing a drogue chute and a parachute chamber containing a parachute. The parachute coupled with the drogue chute with a drogue tether. A riser tether extends between a descent system end portion and a balloon system end portion, and the descent system end portion is coupled with the parachute. A drogue cover release is coupled between the riser tether and the drogue cover. The descent system transitions between riser deployment and parachute deployment configurations. In the riser deployment configuration the system housing is decoupled from the atmospheric balloon system and the riser tether is deployed between the system housing and the atmospheric balloon system. In the parachute deployment configuration the deployed riser tether opens the drogue chamber and deploys the drogue chute and the deployed drogue chute opens the parachute chamber and deploys the parachute.
