The article presents a design-stage ballistics analysis of an orbital transportation system
featuring a Lunar Expeditionary Complex to be assembled in low Earth orbit. The Lunar
Expeditionary Complex includes a manned transportation vehicle, a reusable lunar
lander, a space tug running on oxygen and kerosene, and an integrated upper stage
booster system using oxygen and hydrogen, equipped with extra oxygen tanks. We con-
sider a method of long-term liquid oxygen storage making use of a cryogenic gas liquefi-
er. Since there is no need to store liquid hydrogen for a prolonged period of time, a pas-
sive liquid hydrogen storage system may be set up. The mission profile should require
five unmanned launches of the Angara A5V vehicle and one manned launch of either An-
gara A5P or Soyuz 5 systems. The interval between launches would be approximately a
month. There is no loss of previously launched elements even in the case of a postponed
launch or if losing any other element of the Expeditionary Complex. It is possible to
gradually transition to employing super heavy-lift launch vehicles.
