The launch com

es de a 28-hour countdown. It takes

place in highly suitable weather, w

ith winds 10 knots

from the southeast, tem

perature in the mid-80's, and clouds

at 15,000 feet.

At 4:15 a.m

., the astronauts had been awakened.

After a breakfast of orange juice, steak, scram

bledeggs, toast and coffee, they began suiting up at5:35 a.m

. At 6:27 a.m

., they left in an air-conditionedvan for the launch pad eight m

iles away. A

t 6:54 a.m.,

Arm

strong entered the comm

and module and took

position on the left. He w

as followed five m

inuteslater by C

ollins, on the right, and Aldrin, in the center.

Tw

ere en routeto the pad.T

he Apollo access arm

retracted at 9:27 a.m. E

ightand nine-tenths seconds before launch tim

e, the firstof the S

and the space vehicle began moving slow

ly upward

from the pad, as near 9:32 a.m

. as human effort

could make it.

As it reached the top of the service tow

er, thehard-edged clattering thunder of the firing engines

rolled over the scrubby Florida landscape and engulfed

the viewers like a tidal w

ave. They w

itnessed thebeginning of the fifth m

anned Apollo flight, the third

to the vicinity of the Moon and the first lunar

landing mission.

From

Launch Control the last w

ords were: "G

ood luckand G

odspeed." Com

mander A

rmstrong replied, "T

hankyou very m

uch. We know

this will be a good flight."

9:35 a.m.T

he spacecraft is 37 nautical miles high,

downrange 61 nautical m

iles and traveling at 9,300 feet persecond or about 6,340 m

iles per hour. Arm

strong confirms

the engine skirt and launch escape tower separations.

9:44 a.m.W

ith the three Saturn stages fired one after

another and the first two jettisoned, A

pollo 11 enters a103 nautical m

ile-high Earth orbit, during w

hich the vehicleis carefully checked by the astronauts and by the groundcontrol crew

.12:22 p.m

.Another firing of the third-stage engine, still

attached to the comm

and service module, boosts A

pollo 11out of orbit m

idway in its second trip around the E

arthand onto its lunar trajectory at an initial speed of 24,200m

iles an hour.12:49 p.m

.While the spacecraft m

oves farther and fartherfrom

Earth, the lunar landing craft, code-nam

ed Eagle,

is unpacke;: from its com

partment atop the launch rockets.

The astronauts first fi.e som

e explosive bolts. These

cause the main spaceship, given the nam

e Colum

bia, toseparate from

the adapter and blow apart the four panels

that make up its sides, exposing the lunar m

odule (LM)

tucked inside. They stop the spacecraft about 100 feet aw

ay34 feet farther than they w

ere supposed toturn theship around, facing the landing craft, and dock head-to-headw

ith it. The docking com

plete, the LM's connections w

iththe adapter are blow

n loose and the mated com

mand/service

and lunar modules separate from

the rocket and continuealone tow

ard the Moon.

2:38 p.m.B

y dumping its leftover fuel the third rocket

stage is fired into a long solar orbit to remove it from

Apollo 11's path.

2:43 p.m.W

ith the flight on schedule and proceedingsatisfactorily, the first scheduled m

idcourse correctionis considered unnecessary.2:54 p.m

.The spacecraft is reported 22,000 nautical m

ilesfrom

Earth and traveling at 12,914 feet per second.

Crew

mem

bers keep busy with housekeeping duties.

8:52 p.m.M

ission Control at H

ouston, Texas, says good night

to the crew as they prepare to go to sleep tw

o hoors10:59 p.m

.Because of the pull of E

arth's gravity, thespacecraft has slow

ed to 7,279 feet per second at a distanceof 63,880 nautical m

iles from E

arth.

JULY

178:4P

.Midcourse correction is m

ade with a three-second

burn, sharpening the course of the spacecraft and testingthe engine that m

ust get them in and out of lunar orbit.

7:31 r.m.A

stronauts begin first scheduled color telecastfrom

spacecraft, showing view

of the Earth from

a distanceof about 128,000 nautical m

.Mission control bids the crew

goodnight

JULY

189:41 a.m

.Mission C

ontrol lets Astronauts sleep an hour

later than scheduled on the third day of the outward journey.

After breakfast, they begin housekeeping chores, such as

charging batteries, dumping w

aste water, and checking

fuel and oxygen reserves. Announcem

ent is made to them

that course corrections scheduled for afternoon will not

be necessary.2:57 p.m

.A.s.onauts are given report on day's new

s.4:40 p.m

.One of the clearest television transm

issions eversent from

space is begun, with the spacecraft 175,000

nautical miles from

Earth and 48,000 from

the Moon. It lasts

an hour and 36 minutes. W

hile in progress, the hatch tothe LM

is opened and Arm

strong squeezes through the30-inch-w

ide tunnel to inspect it. He is follow

ed by Aldrin.

10:00 p.m.M

ission Control tells the crew

goodnight.11:12 p.m

.Velocity of spacecraft has slow

oon's sphere ofinfluence at a point 33,823 nautica! m

iles away from

it.

JULY

196:58 a.m

.Astronauts call M

ission Control to inquire about

scheduled course correction and are told it has beencancelled. T

hey are also advised they may go back to sleep.

8:32 a.m.M

ission Control signals to arouse crew

and tostart them

on breakfast and housekeeping chores.10:01 a.m

.Astronauts are given review

of day's news and

are told of worldw

ide interest in Moon m

ission.10:31 a.m

.Collins reports: "H

ouston, it's been a real changefor us. N

ow w

here we have just been able to see stars occasionally and

perhaps through monoculars, but not recognize any

star pattern."10:42 a.m

.Arrnstrong announces: "T

he view of the M

oonthat w

e've been having recently is really spectacular. It fillsabout three-quarters of the hatch w

indow and, of course,

we can see the entire circum

ference, even though part ofit is in com

plete shadow and part of it's in earth-shine.

It's a view w

orth the price of the trip."12:58 p.m

.The crew

is informed by M

ission Control: "W

." Then quickly, seconds later: "you are

go for LOL" A

ldrin replies: "Roger, go for LO

L"1:13 p.m

.Spacecraft passes com

pletely behind the Moon

and out of radio contact with the E

arth for the first time.

1:28 p.m.T

he spacecfaft's main rocket, a 20,500-pound-

thrust engine, is fired for alput six minutes to slow

thevehicle so that it can be captured by lunar gravity. It is stillbehind the M

oon. The resulting orbit ranges from

a low of

61.3 nautical miles to a high of 168.8 nautical m

iles.1:55 p.m

.Arm

strong tells Mission C

ontrol: "We're getting

this first view of the landing approach. T

his time w

e,-..'z.ore going over the T

aruntius crater and xhe pictures and maps

leg brought back by Apo llos 8 and 10 give us a very good

preview of w

hat to look at here. It iooks very much like

the pictures, but like the difference between w

atching a realfootball gam

e and watching it on T

Vno substitute for

actually being here."A

bout 15 minutes later he adds: "It gets to be a lighter

gray, and as you get closer to the subsolar point, youcan definitely see brow

ns and tans on the ground."A

nd a few m

oments still later: "W

hen a star sets up here,there's no doubt about it. O

ne instant it's there and thenext instant it's just com

pletely gone."3:56 p.m

.A 35-m

inute telecast of the Moon's surface

begins. Passing w

estward along the eastern edge of the

Moon's visible side, the cam

era is focused especially on thearea chosen as a landing site.5:44 p.m

.A second burn of the spacecraft's m

ain engine,this one for 17 seconds, is em

ployed while the spacecraft

is on the back side of the Moon to stabilize Ire orbit at about

54 by 66 nautical miles.

6:57 p.m.A

rmstrong and A

ldrin crawl through the tunnel

into the lunar module to give it another check. T

he spacecraftis orbiting the M

oon every two hours.

JULY

209:27 a.m

.Aldrin craw

ls into the lunar module and starts to

power-up the spacecraft. A

bout an hour later, Arm

strongenters the LM

and together they continue to check thesystem

s and deploy the landing legs.1:46 p.m

.The landing craft is separated from

the comm

andm

odule, in which C

ollins continues to orbit the Moon.

2:12 p.m.C

ollins fires the comm

and ship's rockets andm

oves about two m

iles away.

3:08 p.m.A

rmstrong and A

ldrin, flying feet first and facedow

n, fire the landing craft's descent engine for the first time.

3:47 p.m.C

ollins, flying the comm

and ship from behind

the Moon, reports to E

arth that the landing craft ison its w

ay down to the lunar surface. It is the first M

issionC

ontrol has heard of the action. "F.verything's going just

swim

mingly. B

eautiful!" Collins reports.

4:05 p.m.A

rmstrong throttles up the engine to slow

theLM

before dropping down on the lunar surface. T

he landingis not easy. T

hn sae they approach is four mile!: from

thetarget point, on the southw

estern edge of theS

ea of Tranquility. S

eeing that they are approaching a craterabout the size of a football field and covered w

ith largerocks, A

rmstrong takes over hanual control and steers the

craft to a smoother spot. H

is heartbeat has risen from a

normal 77 to 156.

While A

rmstrong flies the landing craft, A

ldrin gives himaltitude readings: "S

even hundred and fifty feet, coming

down at 23 degrees ... 700 feet, 21 dow

n ... 400 feet,dow

ard, drifting to the right a little ...C

ontact iight. Okay, engine stop."

When the 68-inch prubes beneath three of the spacecraft's

four foctpads touch down, flashing a light on the

instrument panel, A

rmstrong shuts off the ship's engine.

4:18 p.m.T

he craft settl.-s down w

ith a jolt almost like that

of a jet landing on a runway. It is at an angle of no rnore

than four or five degrees on the right side of the Moon as

seen from E

arth. Arm

strong imm

ediately radios Mission

Control: "T

he Eagle has landed."

Aldrin, looking out of the LM

window

, reports: "We'll get

to the details around here, but it looks like a collectionof just about every variety of shapes, angularities andgranularities, every variety of rock you could find. T

he colorsvary pretty m

uch depending on how you're looking. .

.

There doesn't appear to be m

uch of a general color at all;how

ever, it looks as though some of the rocks and boulders,

of which there are quite a few

in the near area ... aregoing to have som

e interesting colors to them."

ith this light gray on the outside,but w

hen they've been broken they display a dark, very darkgray interior, and it looks like it could be country basalt."

The first task after landing is that of preparing the ship

for launching, of seeing that all is in readiness .to make the

ascent back to a rendezvous with the com

mand spacecraft

orbiting above.6:00 p.m

.With everything in order, A

rmstrong radios a

recomm

endation that they plan to start the EV

9:00 p.m. E

. Mission C

ontrol replies: "We w

ill supportyou anytim

.Later than proposed at 6:00 p.m., but m

orethan five hours ahead of the original schedule, A

rmstrong

opens the LM h2tch and squee7es through the opening.

It is a slow P

rocess. Strapped to his shoulders is a portable

life supoort and comm

unications system w

Arm

strong moves slow

ly down the 10-foot, nine-step ladder.

On reaching the second step, he pulls a "D

-ring," within

easy reach, deploying a television camera, so arranged on

the LM that it w

ill depict him to E

artn as he proceedsfrom

that point.D

own the ladder he m

oves and halts on the last step."I'm

it the foot of the ladder," he reports. "The LM

footpadsare only depressed in the surface about one or tw

oinches ... the surface appears to be very, very finegrained,as you get close to it, it's alm

ost like a powder."

10:56 p.m.A

rmstrong puts his left foot to the M

oon. It isthe first tim

e in history that man has ever stepped on

anything that has not existed on or originated from the

Earth."T

hat's one small step for a m

an, one giant leap form

ankind," Arm

strong radios. Aldrin is taking photographs

from inside the spacecraft.

The first print m

ade by t..e weight of m

an on the Moon

is that of a lunar boot which resem

bles an oversized galosh.

Its soles are of silicon rubber and its 14-layer sidewalls

of aluminized plastic. S

pecially designed for super-insulation,it protects against abrasion and has reduced friction tofacilitate donning. O

n Earth, it w

eighs four pounds, nineounces; on the M

oon, 12 ounces.A

rmstrong surveys his surroundings for a w

hile and thenm

oves out, testing himself in a gra, ity environm

ent one-sixthof that on E

arth. "The surface is fir e and pow

dery," he says."I can pick it up loosely w

ith my toe. It does adhere in

fine layers like powdered rharccal to the sole and sides of

my boots. I only go in a sm

all fraction of an inch.M

aybe an eighth of an inch, but I can see the footprintsof m

y boots and the trcads in the fine sandy particles."T

here seems to be no difficulty in m

oving around as we

suspected. It's even perhaps easier than the simulations...."

Feeling m

ore confident, Arm

strong begins making a

preliminary collection ot soil sam

ples close to the landingcraft. T

his is done with a bag on the end of a pole.

"This is vely interesting," he com

ments. "It's a very soft

surface, but here and there ..

.I

run into a very hardsurface, but it appears to be very cohesive m

aterial of thesam

e sort.. .. It has a stark beauty all its own. It's like

much of the high desert of the U

nited States."

He collects a sm

all bagful of soil and stores it in apocket on the left leg of his space suit. T

his is done early,according to plan, to m

ake sure some of the M

oon surface isC

SD

returned to Earth in case the m

ission has to be cut short.11:11 p.m

.After low

ering a Hasselblad still cam

era toA

rmstrong, A

ldrin emerges from

the landing craft and backsdow

n the ladder, while his com

panion photographs him.

"These rocks .

.. are

rather slippery," Arm

strong says.T

he astronauts report that the powdery surface seem

s to fillup the fine pores on the rocks, and they tend to slideover them

rather easily.A

rmstrong fits a long focal length lens into position on

the TV

camera and trains it upon a sm

all, stainless steelplaque on one of the legs of the landing craft. H

e reads:"H

rmstrong next rem

oves the TV

camera from

its fixedposition on the LM

and moves it aw

ay about 40 feet so it cancover the area in w

hich the astronauts will operate.

As scheduled, the astronauts set up the first of threc

experiments. F

.From

a leg of the spacecraft, the astronautstake a three-by-five-foot, nylon U

nited States flag, its top

edge braced by a spring wire to keep it extended on

the windless M

oon and erect it on a staff pressed intothe lunar surface.

Taken to the M

back and flown over the houses of C

ongress, the flags ofthe 50 S

tates, the District of C

olumbia and U

.S. territories,

the United N

ations flag, as well as those of 136 foreign

countries.11:47 p.m

.Mission C

ontrol announces: "The P

resident ofthe U

nited States is in his office now

and would like to

say a few w

ords to you." Arm

strong ieplies:"T

hat would be an honor."

11:48 p.m.T

he astronauts listen as the President speaks

by telephone: "Neil and B

uzz. I am talking to you from

the Oval R

oom at the W

hite House. A

nd this certainly has tobe the m

ost historic telephone call ever made .

..

.

For every A

merican this has to be the proudest day of our

lives. And for people all over the w

orldI am

sure they, too,join w

ith Am

ericans in recognizing what a feat this is.

Because of w

hat you have done, the heavens have become

a part of man's w

orld. As you talk to us from

the Sea of

Tranquility, it inspires us to redouble our efforts to bring

peace z..nd tranquility to Earth. F

or one priceless mom

ent, inthe-w

hole history of man, all the people on this E

arthare truly one."

As the P

resident finishes speaking, Arm

strong replies:"T

hank you, Mr. P

resident. It's a great honor and privilegefor us to be here representing not only the U

nited States but

men of peace of all nations. A

nd with interest and a

curiosity and a vision for the future. It's an honor for usto be able to participate here today."

The tw

o astronauts stand at attention, saluting directlytow

ard the television as the telephone conversationconcludes.

Arm

strong next sets up a folding table and opens on ittw

o specimen boxes. U

sing tongs and the lunar scoop,a quantity of rocks and soil are picked up and sealed in theboxes, preparatory to placing them

in the ascent stageof the landing craft.

Aldrin, m

eanwhile, opens another com

partment in the

ship and removes tw

o devices to be left on the Moon, taking

each out about 30 feet from the ship. O

ne is a seismic

detector, to record moonquakes, m

eteorite impact, or

volcanic eruption, and the other a laser-reflector, a devicedesigned to m
