Analytical methods for gravity-assist tour design
… dissertation develops analytical methods for the design of gravity-assist space- craft trajectories. Such trajectories are commonly employed by planetary science missions to reach Mercury or the Outer Planets. They may also be used at the Outer Planets for the design of science tours with multiple …

Machine learning-aided trajectory optimization and tour design
… (ML)-aided methods for preliminary space mission design, with a focus on trajectory optimization and tour design for interplanetary missions involving multiple gravity assists. In early-stage trajectory analysis, the repeated solution of Lambert’s problem often becomes a major computational …

Gravity-assist trajectories to Venus, Mars, and the ice giants: Mission design with human and robotic applications
… with analytical ephemeris via the Satellite Tour Design Program (STOUR), originally developed at the Jet Propulsion Laboratory (JPL). Delivered payload mass is computed for all solutions for select launch vehicles, and attractive solutions are identified as those that deliver a specified …

Robust preliminary design for multiple gravity assist spacecraft trajectories
The development of a new spacecraft trajectory design method most often occurs because a particular capability does not exist. The invention is usually considered successful so long as it is capable of producing solutions to the problem in question, and thus satisfies a particular design …

Spacecraft trajectory optimization using many embedded Lambert problems
… and techniques is critical for better mission design. Preliminary low-fidelity analysis precedes high-fidelity analysis to efficiently explore the space of a problem. The work of this dissertation extends an embedded boundary value problem (EBVP) technique for preliminary design in the two-body …
