five miles above the moon's Dave Scott
and Jim Irwin looked out the window of
their lunar modules down toward Al
Wharton in the command module which have
completed its separation maneuver
beneath them the 15,000 foot feet of the
lunar Apennine mountains soon they would
fly low over those beeps on their way to
a landing in a little valley in the
mountains of the moon
come on fetch over 64 fl PD OPD coming
right out their window they could see
the seam Lewis meanderings of the lunar
Canyon known as Hadley rill as they
brought their lunar module called
science Alton toward his landing and the
beginning of what would be one of the
most significant chapters in the history
of scientific exploration
200 - 1159 7-6
a 23-6 I did 500 feet at five
nine for that few fine at 580 at five -
360 of 350 of 300 look good
forty of three
33:25 - damn guts but seven percent fuel
20 at 115 at 1 - 1 - 1 6 percent fuel 10
feet minus 1
eight feet - one contact and
okay you didn't the falconers on the
plane it had me forever Roger Delta 39
and we had contact instantly heavily
base your television to the back room to
get ready because we've really got tough
for him Stratton Irwin were located on
an undulating plain situated between the
Apennines and Hadley rail an area
selected by the scientists as being one
of the most geologically significant
sites on the moon hey over here dad took
over the ledge two hours after touchdown
Dave Scott stood up in Falcons upper
hatch to survey their landing area oh
boy what have you
I could see put on it Icarus as Scott
stood describing the craters and
mountains we on earth perhaps did not
yet realize the scope and extent of the
coming mission aboard the lunar module
was a small dune buggy like car called
the lunar roving vehicle or just plain
Rover the astronauts would travel miles
in collecting samples and placing and
conducting experiments there are no
sharp jagged peaks are no large boulders
apparent anywhere they would observe the
layering of the lunar terrain most
clearly seen in the formation 14 miles
to the South called Silver Spur this
layering later to be observed in the
mountains and the rill gives scientists
a direct look at the structure of the
moon and the deeper insight as to the
significance of the collected samples
the journey of Apollo 15 had begun four
days earlier July 26 1971 the crew Dave
Scott spacecraft commander and veteran
of Gemini 8 and Apollo 9 Jim Irwin lunar
module pilot who would explore Hadley
rill and the Apennine front with Scott
al worden command module pilot who would
remain in lunar orbit operating an
extensive array of cameras and
experiments and making observations
which when coupled with the surface
worth of Scott and Irwin would give the
most comprehensive picture of the moon's
structure and history ever achieved we
have big plans to launch we are gold 15
seconds guiding internal 13 12 11 10 9 8
ignition sequence our engines are 5
our play and camera program
precisely on schedule 9:34 a.m. Apollo
15 lifted from the pad on its way to the
moon and we have a moment
with the exception of a few minor
problems the trip out with the
uneventful the command module Endeavour
carrying the lunar module Falcon would
arrive in lunar orbit with Scott's
announcement how is the attempted
thoughts tension with cargo and what a
fantastic sight oh this is really
profound I'll tell you this is
absolutely mind-boggling gentlemen I can
well imagine that a foreign planet must
be a weird thing to see July 31st after
a night's rest Dave Scott descended into
the lunar morning
okay as I get out here the wonders of
the undoubtedly I realize her the
fundamental truth to our nature and must
explore and if an exploration it's edit
Chris Scott was then joined by Jim Irwin
Oh
their first job was to get the lunar
roving vehicle out of its storage bay
coming down okay they can afford a
little bit Jim up up that looks good
dirt rocks like soft powder so next the
astronauts tried out the rover during
this test drive one failure showed up
the rover was designed to steer through
both its front and rear wheels hairy
front steering to just escape yeah
in use the absence of front wheel
steering would hardly be noticed then
they loaded the equipment they would
need for their Geological Survey and
boarded the rover for their first
exploration Joe rocker they were headed
towards st. George crater located on a
mountain slope above Hadley rill to the
south of the landing site
earlier or I did it there would be a
stop to collect samples at a smaller
crater called elbow then arrival at the
base of st. George and a look into
Hadley rim Scott then adjusted the
television antenna on the rover a
quarter of a million miles away in
Houston's Mission Control a flight
controller operated the television
camera mounted on the rover scientists
and engineers on earth could directly
monitor the lunar exploration and those
of us at home watching on television
felt like the third astronaut on the
moon the astronauts began to collect
samples and photograph the area the
samples would consist of rocks picked up
with a rake like device soil samples
selected rocks and chips taken from
boulders they would also drive core
tubes into the lunar soil to collect
contiguous specimens from beneath the
surface
but now it was time to return to the
lunar module not to end this first work
period on the lunar service but to begin
another phase I can't believe we came
over the mountain
we did digit the beautiful little valley
get us a big help to fly over the
after returning to the leaven to load
equipment they moved to a nearby
location to set up a science station
similar to those left on previous
mission with the establishment of these
experiments a network of scientific
stations was achieved which would allow
triangulation of events and give us the
ability to locate precisely the origin
of lunar events as they work one of
their instructions was to throw the
packing as far as possible from the site
Dave Scott here Joe Roger tackler
demonstration lovely what was that a
demonstration of by the way it started
out to be up gravity and it they wound
up being over centrifugal force I think
using an electric drill Scott sank a
tube into the lunar soil into which a
probe would be placed to measure heat
flow in the lunar material the
difficulty in drilling would delay
placement of the second probe until the
next day
the science station was then activated
and Scott and Irwin closed Falcons hatch
on Evy a number one miles above the moon
our worden orbited in the command module
endeavor operating experiment his
observations adding to the wealth of
scientific data already accumulated okay
a bucket right down electrode now and a
very interesting thing looks like a
whole field of political standard the
detection of cinder cones clearly of
volcanic origin helped solve another
element of the controversy about how
much of the moon was formed by volcanoes
and how much by meteoroid impact warden
was operating a series of experiments in
the scientific instrument module these
included a mapping camera to shoot lunar
features and simultaneously the star
field for accurate location of these
features a panoramic camera a laser
altimeter for accurate topographical
mapping and the series of experiments to
analyze the chemical makeup of the lunar
crust in the estimation of a number of
scientists this orbital research station
would provide the most important
information collected during the mission
August first Scott and Irwin prepared
for their second day on the moon and as
Scott checked the inoperative forward
steering of the rover show you that some
of those Marshall guys come up here
accepted ship just merge this purchase
my friend their destination was the base
of the Apennine front here they hope to
find some of the basic substance of the
lunar Highlands Drive but you're like
cleanup Mount Hadley at me linear
patterns are really remarkable then they
began the physical sampling of the
Apennine front stopping at four craters
in their Traverse okay everybody go to
work
look at that I'll be putting it there
guess what we just found I think we
found what we came for
yes sir you better believe it to the
untrained eye it looked like just
another rock but it's large crystals
formed in pairs called twinning showed
it to be a section of primal lunar crust
formed during the earliest history of
the solar system not obliterated by
billions of years of impacts and lava
flows it was a key to many mysteries was
the early lunar crust molten why
differences in color and density between
the Highlands and lowlands nicknamed the
Genesis rock it stands as a major clue
in unraveling the formative processes of
the Moon the earth and the planets
Linkous bag number 136 a special bag yes
sir
so this traitor is a gold mine and there
might be diamond to the necklaces yeah
baby
then we saw another practical use of
television in lunar exploration Dave
you're gonna want to cinch up Kim's
collection bag somewhere before you go
much longer keep coming a very loose
there okay let me to the right pair
Jones don't show it over to Roger we
sure don't wanna wear that so I don't
know what would do rod to Joe okay Jim
let's get on her over the back how did
it is okay we're on our tracks Roger and
although they're short and he brought in
that to bear we can spend some more time
on your next trip and extra pure a basic
but needs back that traveling on
tomorrow
they returned to the science station
we're shocked once more man the drill to
place the second heat flow probe and
later to get a deep core sample the
difficulty in drilling was shown by
Scotts hand which would carry bruised
fingernails from his efforts for several
weeks after the mission okay Dave k-car
you've got just one minute of drilling
and over faster it was time to get back
into the LEM and MDV a to the drill and
attached sections were left in the
ground for removal during the next days
Traverse on earth scientists pored over
data from the television from the
astronauts descriptions and from the
orbiting experiments the 1400
photographs the crew would return with
themselves constitute a major scientific
legacy lunar exploration was achieving a
new maturity we are now exploring to
test new hypotheses and the pieces were
fitting together one scientist when
asked why he didn't sit down and rest
after an around-the-clock session
replied I can't I'm too excited a little
bit
and tonight film each other
down to the drill we last left or Fred
now it's our friend oh yes we just get a
shoulder up to that their first stop was
at the drill they had left during the
second DDA this core tube was the
deepest sample ever collected from the
moon
perhaps the deepest we would ever get
eight and a half feet beneath the
surface
cutting through fifty-eight distinct
layers this would not only tell us more
about the lunar structure but contained
in this soil where traces of particles
emitted by the Sun billions of years ago
which would give us a clue to the early
years of the solar system but now it was
time to leave the core tubes to be
picked up later and head west northwest
to the rim of Hadley rail
look at that real me how about that
I could see babies you did very well the
fine Blazers with a back unit
I got all right three softer
then Scott and Irwin descended a short
distance over the rim of Hadley rail to
get a piece of one of the large blocks
thought to be lunar bedrock chunk of the
bedrock you go closer make a bet big
jump editor boy
they buckled their seatbelt for the ride
back to the lunar module financially
first look at the mountain today Jim
when they're all sunlit isn't that
beautiful
Billy yes by golly that just super you
know unreal
hey I'm reminded of a favorite biblical
passage from Psalm I look after the
hills from whence cometh my help but of
course we get quite a bit from human too
after a stop to pick up the core samples
they return to the lemon to close out
their final traverse the first Scott
would make history canceling a stamp on
an interplanetary envelope I'm very
proud to have the opportunity here to
play postman what could be a better
place to cancel damp then right here
Callie real then a demonstration of a
classic experiment feather my right hand
a hammer I guess one of the reasons we
got here today was because of a
gentleman named Galileo a long time ago
who made a rather significant discovery
about falling objects of gravity field
and we thought that there would be a
better place to confirm his findings on
the moon and so we thought we'd try it
here for you and the feather happens to
be appropriately a falcon feather for
our Falcon and I'll drop the two up here
and hopefully they'll hit the ground at
the same time how about that mr. Galileo
was correct in his findings
finally Scott drove the rover away from
the LEM so that its TV camera could pick
up a picture of the coming liftoff as
the spaceport rifling would say we're
ready for you to come back again to the
home cement on the cool green hills of
Earth 171 hours and 37 minutes after
they had lifted off the planet Earth
Scott and Irwin would lift off its
sister planet accompanied by a musical
salute they themselves would provide
from a small tape recorder onboard
freeze roaches
Pinkett Smith Ryder
we have like two winners I did it I
wanted view of the real
Oh
the rendezvous and docking procedures
were flawless right on the money but
their jobs were not over they would
spend two more days in lunar orbit
gathering data from the experiments and
photography one more day around the moon
than any preceding mission on August 4th
they prepared to come home but even on
their last orbit of the moon they had
another experiment
a very pretty satellite up hill they
placed in orbit a sub satellite the
first ever launched by a manned
spacecraft it was designed to circle the
moon for a year measuring variations in
lunar gravity the strength and direction
of interplanetary and earth magnetic
fields and the flow of charged particles
in space tracking stations have acquired
the satellite oh very good
then the burn to bring them back to
earth but their jobs were far from over
170 2,000 miles from Earth al worden
left the spacecraft to retrieve the
eight thousand feet of film contained in
the cassettes of the experiment Bay
cameras later they would turn their
x-ray spectrometer toward the newly
discovered x-ray pulsar
those mysterious black holes in space at
the same time in accord with the
previous plan an earth-based Soviet
Observatory scanned the same areas
visually to help derive a model
consistent with both sets of
observations during the trip home the
x-ray spectrometer would observe seven
x-ray sources and gather 50 hours of
galactic data then on August 7 they
looked into the fireball created by the
heat of their re-entry into the Earth's
atmosphere at 25,000 miles per hour
and there would be a heart-stopping
moment as one of the three parachutes
collapse however the landing system was
designed to use two parachutes the third
parachute was an added safety factor
today that margin paid off
the success of Apollo 15 have been
spectacular the scientific results have
been almost unbelievable in the words of
one scientist a five for one mission yet
while we rejoice in our success we
cannot afford to forget the sometimes
painful efforts that gave us these
achievements spacecraft commander Dave
Scott I think many people have
contributed to this pinnacle we've
reached some have contributed more than
others and we know of 14 individuals who
contributed all they had and because of
that why we left a small memorial on the
moon about 20 feet north of Rover one
and a small subtle crater there's a
simple plaque for 14 names and those are
the names in alphabetical order of all
the astronauts and cosmonauts who have
died in the pursuit of exploration of
space near Earth is a small figure
representing of fallen astronaut we went
to the moon as trained observers in
order to gather data not only with our
instruments on board but with our minds
I'd like to quote a statement from
Plutarch which I think expresses our
feelings since we've come back the mind
is not a vessel to be filled but a fire
to be lighted thank
