Magnetoshell Aerocapture: Advances Toward Concept Feasibility
Magnetoshell Aerocapture (MAC) is a novel technology that proposes to use drag on a dipole plasma in planetary atmospheres as an orbit insertion technique. It aims to augment the benefits of traditional aerocapture by trapping particles over a much larger area than physical structures can reach. …

Aerocapture guidance methods for high energy trajectories
… of an existing numerical predictor-corrector aerocapture guidance algorithm (PredGuid). The study includes implementation of an energy management phase prior to targeting with a generic method of transition and replacement of heuristic features with more generic features. The vehicle response …

Assessment of aerocapture-entry trajectories for human Mars exploration
Using aerocapture to insert into an elliptic parking orbit prior to entry, descent, and landing is being explored for human Mars missions. These aerocapture-entry trajectories have advantages over a direct entry, but the advantages come at the cost of additional entry system mass. The goal of this …

An Aerocapture Guidance and Estimation Framework for Improved Robustness to Uncertainty
Aerocapture is an orbital insertion maneuver that converts a hyperbolic approach trajectory into a desired captured orbit using the aerodynamic forces generated during a single atmospheric pass. While it offers major benefits, such as reduced interplanetary cruise time and lower propellant mass …

Analysis of Transfer Trajectories Utilizing Sequential Saturn-Titan Aerocaptures
… potential of a transfer orbit using successive aerocaptures at Saturn and Titan to establish a science orbit around Titan. Titan is an Earth-like moon with a dense atmosphere and organic compounds present. It has many similarities with Earth that are useful to study such as superrotation. …

Interplanetary mission design with applications to guidance and optimal control of aero-assisted trajectories
… heat load optimal trajectories are found for aerocapture maneuvers at Uranus and Neptune. With a large radius, and short rotational periods, atmospheric rotation must be taken into account to accurately model the system dynamics.</p> <p>Investigation of the 2018 Inspiration Mars free-return …
