We construct a cycler (with acceptable transfer times and moderate encounter velocities) by patching a series of three-synodic-period semicycler trajectories together. The cycler employs high-efficiency low-thrust propulsion for trajectory maintenance and correction (thus making it a "powered" cycler). Even though the propellant usage is not insignificant, we believe that this cycler still compares favorably with ballistic cyclers (that is, cyclers that do not require deterministic maneuvers… Expand

Low-thrust roundtrip trajectories to Mars with one-synodic-period repeat time
Abstract Cycler trajectories—both ballistic and powered—are reported in the literature in which there are two-vehicle, three-vehicle, and four-vehicle cases. Such trajectories permit the installationExpand
Notable Two-Synodic-Period Earth-Mars Cycler
Earth-Mars cycler trajectories (cyclers) could play an important role in a future human transportation system to Mars. A particular cycler that repeats every two synodic periods and has oneExpand
Establishing cycler trajectories between Earth and Mars
Abstract Several cycler concepts have been proposed to provide safe and comfortable quarters for astronauts traveling between the Earth and Mars. However, no literature has appeared to show how theseExpand
Continuous Mars Habitation with a Limited Number of Cycler Vehicles
We present cycler and semi-cycler trajectories to transport crews from Earth to a Mars base and back. It is assumed that the Mars base should never be abandoned and that the cycler vehicles safelyExpand
Analysis of a Class of Earth-Mars Cycler Trajectories
TLDR
A new, systematic method for constructing and evaluating cyclers is described, which reveals that previously known cyclers, such as the Aldrin cycler and the Versatile International Station for Interplanetary Transport cycler, belong to a larger family of cyclers. Expand
Low-Thrust Aldrin Cycler with Reduced Encounter Velocities
The Aldrin cycler has been proposed as a transportation system for human missions between Earth and Mars. However, the hyperbolic excess velocity values at the planetary encounters for these orbitsExpand
Guidance Strategy for Hyperbolic Rendezvous
In cycler and semi-cycler Mars mission architectures a crew “taxi” docks with the interplanetary transfer vehicle on a hyperbolic flyby trajectory, hence the term “hyperbolic rendezvous.” AnExpand
Reduced Parameterization for Optimization of Low-Thrust Gravity-Assist Trajectories: Case Studies
Low-thrust trajectories can be modeled as a series of impulsive ( ΔV) maneuvers connected by conic arcs. We study new ways of parameterizin g the ΔV vectors with a reduced number of variables andExpand
Optimization of a broad class of ephemeris model earth-mars cyclers
TLDR
The current study presents a method to optimize accurate model cyclers based on simple model solutions and catalogs the results for a broad class of ephemeris model Earth‐Mars cyclers. Expand
Trajectories for Human Missions to Mars, Part 1: Impulsive Transfers
TLDR
The energy requirements of the trajectories decrease with increasing flight times, and the optimal A V is reduced by up to 50% when the flight time limit is increased from the NASA-recommended 180 days, to 270 days. Expand
