re: Out of Low Earth Orbit
Another Delta-4 could be launched, 29 days earlier, to send a 2-seater lunar-lander to the moon to park it in lunar-orbit, awaiting the the arrival of the 3-person CEV.
And yet another Delta 4, launched 59 days before the CEV, could send a habitation/laboratory module to the lunar surface to house two astronauts for upto two weeks on the surface.
