requirements for circularization at apocynthion and subsequent phase -angle
reduction prior to rendezvous initiation. The apocynthion altitude of the standard
orbits can be adjusted, to the proper altitudes for circularization and phasing for

A chart was developed to aid the pilot in selecting an initial thrust level and thrust
vector orientation angle as a function of separation distance at apocynthion (fig. ll
). The data for the figure were obtained on the basis that the apocynthion ...

Apollo in Perspective: Spaceflight Then and Now
At this moment the lunar module's descent engine was fired to slow the craft
down and move it into an elliptical orbit, the firing point becoming the
apocynthion, with a pericynthion of 15 km at a point 14 up-range of the landing
site. This burn ...
The second number — the “a” — for apocynthion. These two numbers told them
something about the shape of their orbit. The two numbers, stated in kloms,
represented the craft's closest and farthest approaches to the body they were
circling, ...
These were pericynthion and apocynthion readings — or closest and farthest
approaches to the moon. Any old body whizzing past the moon could get a
pericynthion number, but the only way you could get pericynthion and
apocynthion was ...

Glossary of Mapping Science
apocynthion - SEE apolune. apofocus - That point, in an elliptical orbit, at which
the moving body is farthest from the focus where the attracting mass is located.
Also called apoapsis and apocenter. It is at the opposite side of the orbit from the

STATEMENT OF PROBLEM The purpose of this study is to examine a simple
procedure for determining the apocynthion and pericynthion altitudes of the orbit
resulting from the standard orbit modification when the transfer vehicle is initially

Errors in altitude have some effect on pericynthion altitude and practically no
effect on apocynthion altitude. It was assumed in this investigation that the
transition of the ferry vehicle from landing attitude to the attitude at abort initiation
occurred ...

A Compilation of Recent Research Related to the Apollo Mission
Instead of correcting an injection-velocity error, the following maneuvers might be
considered: (1) When the LEM reaches apocynthion, it can add enough AV
tangentially to go into a circular orbit at the apocynthion altitude and (2) Apollo
can ...
