Development of a Long-term Earth-Mars Cycling Vessel
StarGate Research Laboratory - PI, Inc.
Spacecraft developed for extended-duration cycling between the Earth and Mars can represent a direction toward development of a “clipper ship” for colonization, exploration and transportation of personnel and cargoes using the same components for structure, shielding, coolant, and fuel as other ships and space platforms. This type of long-term, interplanetary spacecraft represents an extension not only of current technology, but also a means to create systems destined for service in terms of years, which is a critical parameter for optimizing the performance of interplanetary and potential interstellar spacecraft. A quantitative analysis is presented of the kinematics of a single stage interplanetary cycling ship. In the limiting case of a spacecraft on a continual mission with no deceleration at the either aphelion or perihelion, a dead-weight fraction of 10-3, with the brennschluss velocity of 3.2m/s (providing a consistent 0.6-0.8 g of artificial gravity to its occupants) would enable “contact” between Earth and Mars on an average of every 275 days.
