A system for emergency crew return and down-mass orbit comprising a stowable, self-contained, deployable maneuvering reentry vehicle for automated, on-demand reentry to ground for cargo of 1-10 kilograms or up to single or multiple human use for evacuation of orbital facilities. The system includes a deployable “aeroshell” that is contiguous (a single geometric object—surface or hollow shape—that can morph in 3D shape), modular (a collection of modular components externally acting as a contiguous shape, but morphed in 3D via actuators contained in each modular member to create a general asymmetric geometry), or discontiguous (a collection of independently controlled surfaces or bodies that morph to form desirable asymmetric drag configurations). The system contains traditional spacecraft guidance, navigation and control, propulsion, and attitude control elements, in addition to communications, power, and actuator energetics systems for controlling the vehicle aeroshell shape during reentry, thus, minimizing the landing footprint of the vehicle.

The system, as recited in claim 8, wherein said aeroshell is discontiguous. 11. The system, as recited in claim 8, wherein said plurality of radially axisymmetric panels may be selectively extended independent of each other panel. 12. The system, as recited in claim 11, wherein said plurality of radially axisymmetric panels may be extended collectively. 13. The system, as recited in claim 12, wherein said payload is comprised of time sensitive results from biological and pharmaceutical manufacturing processes and experiments. 14.
