*Hybrid (H) trajectory used.
**Based on 108 ° launch azimuth upper limit.
***Sun Elevation Angle (SEA) - assumes launch at window opening
and translunar injection at the first opportunity.
NOTE: A hybrid trajectory is required for a launch on 18
July to make it possible for the Goldstone tracking
station 210-foot antenna to cover the LM powered
descent phase.
Since this mission includes a lunar landingt the flight is designed such that the sun is
behind the Lunar Module (LM) and low on the eastern lunar horizon in order to optimize
visibility during the LM approach to one of the three Apollo Lunar Landing Sites available
during the July monthly launch window.
