a transearth perigee radius equal to that of its translunar perigee, will have its
pericynthion on the earth-moon axis (neglecting perturbations). This requirement
of the pericynthion position of this type of trajectory is quite intuitive considering
the ...
With a short burn of its descent engine, which slowed the spacecraft down by 22
m/s, the LM now began the descent to the surface by entering an elliptical orbit
with a pericynthion altitude of 1 5 km. The pericynthion point was, of course, ...

Apollo 12 - On the Ocean of Storms: On the Ocean of Storms
A nominal trajectory would yield a low-pericynthion free-return passage behind
the Moon that would return the spacecraft to Earth without further thrusting in the
event of lunar orbit insertion not occurring. A hybrid trajectory was to yield a ...

How Apollo Flew to the Moon
“It might be interesting to note that after sightings, we ran out P21, and we got a
pericynthion of 66.8 [nautical] Inertial measurement miles." "mt What Lovell had
done was to use hlavigation P21 in the spacecraft's computer. 359 This
program's ...
The first number — the “p” — stood for pericynthion. 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 ...

The purpose of the descent orbit insertion (DOI) burn, performed by the
separated LM, is to establish its new pericynthion, 50,000 feet above the moon
from which the LM will initiate powered descent. Steve thought, it's ironic what the
rigors of ...

Thirteen: The Apollo Flight That Failed
The burn was scheduled for eight-thirty that evening, which would be two hours
after pericynthion — the spacecraft's closest approach to the back side of the
moon — and hence it was called the PC +2 burn. Pericynthion was the point at
which ...
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 ...
Jim Lovell, Jeffrey Kluger, 2006
location of the pericynthion of the resulting orbit is affected. (See fig. 11(c).) Thrust
- angle errors of 0.5° can shift the pericynthion location by as much as 6°. Several
additional errors including errors in thrust magnitude and errors in velocity and ...
