Previous research has analyzed proposed missions utilizing spacecraft in Lissajous orbits about each of the co-linear, near-Mars, Sun-Mars libration points to form a communication relay with Earth. This current effort focuses on 2016 Earth-Mars transfers to these mission orbits with their trajectory characteristics and sensitivities. This includes further analysis of using a mid-course correction as well as a braking maneuver at close approach to Mars to control Lissajous orbit insertion and the critical parameter of the phasing of the two-vehicle relay system, with one spacecraft each in orbit about L_1 and L_2. Stationkeeping sensitivities are investigated via a Monte Carlo technique. Commercial, desktop, simulation and analysis tools are used to provide numerical data; and on-going, successful collaboration between military and industry researchers in a virtual environment is demonstrated. The resulting data should provide new information, on these trajectory sensitivities to future researchers and mission planners.
