Circulating transportation orbits between earth and Mars

Preliminary Analysis of Establishing Cycler Trajectories Between Earth and Mars via V? Leveraging

“…The trajectories considered for establishment are the Aldrin Cycler, 9 the VISIT cyclers, [10][11][12] and various two synodic period cyclers. 13,14 The orbital elements of the various cycling trajectories are presented in Table 1.…”

“…Perhaps the simplest and most famous of the Mars cyclers is the Aldrin cycler, named for Buzz Aldrin. 8,9 Several other types of cycler trajectories have been offered as possible solutions by Niehoff; 10,11 Friedlander et al; 12 Brynes et al; 13 McConaghy et al; 14 and Russell and Ocampo. 15 Each of these have their advantages and disadvantages, but the problem of getting cycler vehicles into their cycler orbits is significant, and establishing these transfer trajectories has not been investigated.…”

Rapid Interplanetary round Trips at Moderate Energy

“…Nearly all of the interplanetary round trip analysis to date has focused on minimum energy round trips or small deviations from minimum energy. (See, for example, the excellent work by Aldrin [1985], Friedlander, et al [1986], Hoffman and Soldner [1985], Hoffman, McAdams, and Niehoff [1989], Polsgrove and Adams [2002], and Young [1988].) Certainly this is a practical approach given the high cost of rocket travel.…”

A Low-Thrust Version of the Aldrin Cycler

“…EVERAL circulating orbits have been proposed over the years to enable periodic human missions between Earth and Mars. [1][2][3][4][5][6][7][8] These cycler concepts can be traced back as far back as the late 1960s. A particular cycler, called the Aldrin cycler, is the focus of this paper.…”
