The last 20 Space Shuttle flights for the Quarter will be used for scientific endeavors.
Fourteen shuttles will be needed for orbital science, with the majority of the flights used for rocket propellant (Table 1).
The propellant will be used to boost science equipment and personnel to a higher orbit.
::
Only one set of science equipment will head to the lunar surface every Quarter. The rest of the shuttle flights will be used to refill the propellant tanks of a Cislunar Vehicle (CV).
Lunar Vehicles operating from the Moon will bring the science equipment down to the lunar surface.
