Astronauts call Mission
Control to inquire about scheduled course correction and are told it has
been cancelled. They are also advised they may go back to sleep.
Mission Control signals
to arouse crew and to start them on breakfast and housekeeping chores.
Astronauts are given
review of day's news and are told of worldwide interest in Moon mission.
Collins reports: "Houston,
it's been a real change for us. Now we are able to see stars again and
recognize constellations for the first time on the trip. The sky is full
of stars, just like the nights on Earth. But all the way here we have
just been able to see stars occasionally and perhaps through monoculars,
but not recognize any star pattern."
"The view of the Moon that we've been having recently is really spectacular.
It about three-quarters of the hatch window and, of course, we can see
the entire circumference, even though part of it is in complete shadow
and part of it's in earth-shine. It's a view worth the price of the trip."
The crew is informed
by Mission Control: "We're 23 minutes away from the LOI (Lunar Orbit Insertion)
burn. Flight Director Cliff Charlesworth is polling flight controllers
for its status now." Then quickly, seconds later: "You are go for L0I."
Aldrin replies: "Roger, go for LOI."
Spacecraft passes completely
behind the Moon and out of radio contact with the Earth for the first
The spacecraft's main
rocket, a 20,500-pound-thrust engine, is fired for about six minutes to
slow the vehicle so that it can be captured by lunar gravity. It is still
behind the Moon. The resulting orbit ranges from a low of 61.3 nautical
miles to a high of 168.8 nautical miles.
Armstrong tells Mission
Control: "We're getting this first view of the landing approach. This
time we are going over the Taruntius crater and the pictures and maps
brought back by Apollos 8 and 10 give us a very good preview of what to
look at here. It looks very much like the pictures, but like the difference
between watching a real football game and watching it on TV-no substitute
for actually being here."
About 15 minutes
later he adds: "It gets to be a lighter gray, and as you get closer to
the subsolar point, you can definitely see browns and tans on the ground."
And a few moments
still later: "When a star sets up here, there's no doubt about it. One
instant it's there and the next instant it's just completely gone."
A 35-minute telecast
of the Moon's surface begins. Passing westward along the eastern edge
of the Moon's visible side, the camera is focused especially on the area
chosen as a landing site.
A second burn of the
spacecraft's main engine, this one for 17 seconds, is employed while the
spacecraft is on the back side of the Moon to stabilize the orbit at about
54 by 66 nautical miles.
Armstrong and Aldrin crawl through the tunnel into the lunar module to
give it another check. The spacecraft is orbiting the Moon every two hours.
