Initial Conditions Analysis for Spacecraft Atmospheric Return from the Moon
Entry conditions after spacecraft return from the Moon are considered for landing in given place. Entry angles (or altitude of conditional perigee), latitude and longitudes of entry points as well as range of descent distances depending on entry point latitude (or return date) are considered. It is shown the possibility to use ascending trajectory (with crossing the landing place parallel) or descending trajectory (without crossing the landing place parallel). The estimations are obtained for lowest achievable value of maximal load factor and minimal possible altitude at the phase of spacecraft first entry the Earth atmosphere.
