Optimal Circle-to-Ellipse Orbit Transfer for Sun-Facing E-Sail

open access: yesAerospace, 2022
The transfer between two coplanar Keplerian orbits of a spacecraft with a continuous-thrust propulsion system is a classical problem of astrodynamics, in which a numerical procedure is usually employed to find the transfer trajectory that optimizes (i.e.,

Electric solar wind sail mass budget model [PDF]

open access: yesGeoscientific Instrumentation, Methods and Data Systems, 2013
The electric solar wind sail (E-sail) is a new type of propellantless propulsion system for Solar System transportation, which uses the natural solar wind to produce spacecraft propulsion.

Electrodynamic tethers for spacecraft propulsion [PDF]

open access: yes36th AIAA Aerospace Sciences Meeting and Exhibit, 1998
Relatively short electrodynamic tethers can use solar power to "push" against a planetary magnetic field to achieve propul sion without expenditure of propellant. The groundwork has been laid for this type of propulsion. Recent important milestones include retrieval of a tether in space (TSS-1, 1992), successful deployment of a 20-km-long ...
