Time-optimal spacecraft rotations have been developed and implemented on orbiting spacecraft, highlighting opportunities for improving slew performance. Double-digit reductions in the time required to slew from one attitude to another have been demonstrated. However, the ability to perform mission planning to make use of minimum time slewing maneuvers is largely precluded by the need to compute a numerical solution to find a single minimum time maneuver control trajectory. Machine learning...

Autonomous vehicle teams have great potential in a wide range of maritime sensing applications, including mine countermeasures (MCM). A key enabler for successfully employing autonomous vehicles in MCM missions is motion planning, a collection of algo-rithms for designing trajectories that vehicles must follow. For maximum utility, these algorithms must consider the capabilities and limitations of each team member. At a minimum, they should incorporate dynamic and operational constraints to...

This work introduces the use of optimal control methods for simultaneous target sequencing and dynamic trajectory planning of an autonomous vehicle. This is achieved by deriving a control solution that minimizes a cost to maximize target selection. In the case of varying target priorities, the method described here preferentially selects higher priority targets to maximize total benefit in the allowed time horizon. Traditional techniques employ heuristic techniques for target sequencing and...

Most mission concepts that return sample material to Earth share one common element: an Earth entry vehicle (EEV). The primary focus of this paper is the examination of EEV design space for relevant sample return missions. Mission requirements for EEV concepts can be divided into three major groups: entry conditions (e.g., velocity and flight path angle), payload (e.g., mass, volume, and g-load limit), and vehicle characteristics (e.g., thermal protection system, structural topology, and...
