ABSTRACT
The principal geological objectives of --Early Apollo missions
will be study of the fine s t ruc ture of the lunar surface, mainly
in the plains a r e a s favorable for ear ly lauding, and study of the
ilature of the plains mater ials . Plains a r e a s of interest include
not only the mar ia , but a l so the plains of cer tain upland regions.
These plains a r e depositional surfaces, modified by post-
depositional processes of several The pr imary questions
to be answered a r e 1)the lithologic composition, s t ructure, a t ~ d
thicklless of the superficial layer of fragmental mater ia l believed
to cover most par t s of the plains and other a r e a s on the moon
and 2) the composition and origin of the mater ia l underlying the
plains.
Allswers to these questions will be obtained from the geo-
logical observations of the a s t ro~ lau t s , fronl photographs, and
from sarnp1.e~ taken along a se r i e s of foot t r a v e r s e s from the
lunar excursion module. The geological instruments to be used
by the astronauts a r e light, simple hand tools and cameras . The
topographic and geologic relations observed along the t r ave r ses
of the astronauts will be determined primari ly from numerous
stereoscopic photographs supplemented by the astronautsq
descriptions alld by data obtai~led from returned samples. The
photographs provide a detailed record of the surface features,
which can la ter be analyzed quantitatively, and will provide the
-
geologic context a t the s i te of each sample locality. The orien-
tation of the cameras during exposure of each photograph will
be automatically recorded for use in later photogrammetric and
photometric data reduction.

TECHNICAL SECnON
A. Scientific objectives
The ea r ly Apollo lullar landing s i t e s will probably be on
mar ia floors or other lunar plains, r emote from rugged topo-
graphy. These plains a r e depositional sur faces , modified by
post-depositio~lal processes of seve ra l kinds. The pr imary
geological questions to be answered by e a r l y Apollo l u ~ l a r
lailding missions a r e I ) the nature and origill of the mater ial
underlying these plains, and 2) the nature and r a t e s of the
processes that have taken place on the lunar surfa.ce. Were the
plains ma te r i a l s formed as flows of liquid lava that now range
from solid rock to rock froth, or were they deposited a s a s h o r
granular mater ia l , and now range f rom unconsolidated to solid
depending on the degree of heat o r vacuum welding? The r a t e s
of processes modifyillg the sur faces of the plains a r e exceed-
ingly slow; these processes call best be approached by study of
their long-term effects 011 mater ia l s and topographic forms of
the plains.
The most immediate question will be the composition, fine
s t ruc ture , and thickness of a superficial layer of fragmental
mater ial believed by many studellts of the moo11 to have been
formed by the impact of objects of var ious s i zes over a very
loilg period of t ime. Closely related t o the origin of this
http:surfa.ce
-
mater ia l , is the distribution and range in size and shape of
craters which pockmark the surface, as seen in the Railger VII,
VIII and IX photographs.
B. Fine s t ruc ture of the plains surfaces
Models of the local fine s t ruc tu re of the plains can be
derived f rom physical studies of the moon's surface, by means
of telescopic photometry, radiometry and reflected microwave
signals, and observations of the lunar c r a t e r distribution in
combination with empir ical knowledge of the phenomenology of
c ra te r ing , c ra te r ing theory, curreil t data 011 the flux of meteor-
oids in the vicinity of the ear th, and es t imates of the effects of
other processes acting on the lunar sur face , such a s sputtering
produced by so la r wind bombardment. P rom such stuclies we already
know that the lunar c r u s t i s demoilstrably heterogeneous in com-
position. The fine s t ruc ture of the sur face a l so may be expected
to be heterogeneous.
On the basis of the available data , i t appears highly probable
that most par t s of the moon's sur face a r e covered with a layer of
finely broke11 rock fragmeilts, the upper surface of which i s
pitted with c r a t e r s . The thicklless of the layer , the s i z e d is t r i -
bution of the rock fragments, and the s i ze and spacing of super-
imposed c r a t e r s probably a l l v a r y abruptly from place to place.
Employiilg the data available from the photographs acquired from
the Iiailger missions, in addition t o the illformation obtained a t
-
the telescope, a reasonable model of the fine s t ruc ture of a
typical local area on a plains su r face can be described in the
following way:
1. A layer of shattered and pulverized rock probably
covers m o r e than 95 percent of the plains. It is of var iable
thickness and r e s t s with i r r egu la r contact on the uilderlying
substailce of the plains.
2. The fragments in this layer o r blanket of shattered
rock have been derived by ejectioil f rom c r a t e r s , most of
thcrn nearby, but some lying g rea t dis tances away. About
50 percent o r m o r e of the fragments have come from within
one kilometer of the s i te , but t he re is a fiilite probability,
decreasii lg with the distance t o the source , of findiilg a rock
fragmeilt derived from any place on the moon. Except alollg
the margins of a plain, therefore, the pieces of debris will
be composed predomi~lantly of plaiils mater ial . Those frag-
ments that have come from beymd the plains will probably
represell t highly d iverse geologic environments. In addition,
a smal l admixture of meteorit ic mater ia l will probably be
represell ted among the rock debris .
3. F r a g m e ~ l t s occurring a t the base of the debris layer
will, on the average , have been t ransported on ballistic
t ra jec tor ies a sma l l e r ilumber of t imes than pieces near the
middle o r top of the layer . Progressing upward from the
base, the layer has been s t i r r e d o r recoilstituted an
-
increasing number of times by smaller and smaller and
more and more numerous cratering events. The uppermost
millimeter of the debris layer is probably completely
reorganized once every 10 to 100 years by the formatioil and
filling of minute craters.
4. The average grain size tellds to decrease from base
to top of the debris layer because fragments in the upper
part, oil the average, have been shocked and broken a
greater llumber of times and have been ejected, on the
average, from smaller craters. Near the base, fragments
as large as several centimeters in diameter will be common,
whereas the material of the uppermost few millimeters more
likely will be fillely pulverized. Throughout the debris
layer, the bulk of the rock fragments will probably average
less than a millimeter in grain size, but heaps of coarse
blocky rock from the larger craters may be expected at
many places.
5. Beneath this blanket of shattered rock, the plains sub-
stance, i f originally solid, will in many places show evidence
of having been broken to greater depths by shocks of varying
strength produced during developmellt of the larger craters.
6. The contact between the uilderlying material and the
pulverized surface blanket has collsiderabl e local relief,
collsisting chefly of the intersecting segments of the ori-
ginal floors and walls of nuillcrous old craters that
-
range from a meter to a few tens of meters across. Most
of these are now buried belleath younger impact debris.
7 . The upper surface of the debris layer is pockmarked
by craters ranging from less than a millimeter to several
tens of meters across (or larger dependingonthe local area).
Craters larger thall one meter in diameter occupy about
50 percent of the surface; smaller craters occupy the rest
of the surface and are also superimposed on the large craters.
Millute craters, with dimensions of the order of a millimeter
or less, probably cover nearly all of the surface and are
superimposed on nearly all other features.
8. The debris layer typically varies in thickness from
a few tens of meters to less $hall a millimeter, It is
thickest where it covers the floors of some of the oldest
and largest craters, and is thin or even absent along the walls
of very young craters that cut through the debris layer into
the underlying plains material.
A similar layer of pulverized rock probably covers nearly
all parts of the moon's surface. It can be expected to vary in
average thickness as a direct functioil of the age of the rocks or
terrain 011 which it is formed. Terrain older than the maria
will have a thicker blallket of debris than the typical mare
surface, and the blanket will be thinner, on the average, on
younger terrain. The average crater size on the surface of the
debris layer will be larger on older terrain and smaller on the
younger terrain.
-
Examiilatioil of the surf ic ial layer , possible alteration pro-
f i les , and the underlyiilg lunar plains mater ia l s , preseilt a
challengiilg problem for the astronauts , but one that can be
attacked by straight -forward field procedures. Direct visual
examination and sampliilg of the sur face will answer many of the
c r i t ica l questions. A systematic study over an extended period
of t ime will be necessary , however, if the surface s t ruc tu re i s
to be fully understood. Such a study requ i re s that as complete
a r eco rd a s possible be obtained of the shape, s i ze , and spatial
dis t r ibut ioi~ of sur face features a i ~ d mater ia l s . I11 o r d e r t o
analyze the fine s t ruc ture of ally par t of the moon's surface, i t
must be possible to reduce this observational information to
a geometr ic a r r a y , commonly portrayed by geologic maps and
c r o s s sections. Such a r r a y s o r maps contain, in a reduced
fo rm, the illformation derived f rom visual observations, samples ,
photography, and physical measurements r emrned from the moon.
If the astronauts have been fully trailled in the techniques of
accura te aild thorough observation and reporting, descriptions of
the i r visual observatioils of the lailding s i te , recorded on tape
and by rad io commul~ica t io i~ to the ea r th , will be an important
element of the scieiltific record . Abundant high- resolution
photography by film will provide an equally important form of
r eco rd from which much of the on-s i te descriptioil and analysis
call be amplified and verified, and f rom which topographic and
geologic maps of the landii-tg s i t e call be constructed. The
-
returned samples provide the third major source of geologic
information. The hand specimen descr ipt ions, mineralogy,
petrography, chemis t ry , and nuclear composition of the samples ,
when evaluated together with the field geologic information, will
complete the geologic data required t o in te rpre t the nature and
origin of the lunar plains.
-
The immediate objectives of the Apallo geologic field inves-
tigations may be described concisely a s the deterrninntio~~ of t h e
local structure and character of the luilar surface n~atericcils and
the processes and sequeilce of events by which these materials
and the structure have originated. Structure, used here in its
broadest sense, refers to the threedimensioi~al array of the
different types of material present in the area studied, aild the
physical and temporal relationships of each type of material to
the others,
To determine structure, it is necessary first to be able to
discriminate or recognize differences in the materials present
and the11 to be able to locate materials with observed differences
within a three-dimensioilal array or coordinate system. The
scientific iilstrurnents proposed here a r e chosen to provide a
detailed permanent record of the visual illformation needed to
discrimillate and correlate differem lui-nar surface materials, the
data necessary to order this information in a geometric array,
and equipment to obtain samples that a r e correlated with the
visual data.
The principal record of the geologic details of the lunar
surface will be provided by photographs. From th? photographs
the morphological details of the surface, railging from the near
microscopic textures to the major topographic elemeuts of the
-
landiilg s i te , can be reconstructed. Measurements obtained from
the photographs are used to construct maps, profiles, and three-
dime~lsional models, which serve a s a bases on which to plot
geologic information. In addition to morphology, information on
photometric propert ies and color of the sur face mater ia l s can be
accurately recorded in the photographs. These a r e the chief
killds of information used by the geologist t o discr iminate differ-
ent rock mater ia l s and t o decipher geologic s t ruc tu re in the field. .
A s tereometr ic film camera , ca r r i ed by the astronaut and
moullted on a11 instrument holder configured as a walking o r
surveying staff, is the principal geological instrument. With the
aid of a gnomon placed on the surface, the location, shape, and
orientation of fea tures on the lunar surface may be extracted
f rom the photographs by the methods of photogrammetry. These
features will include objects well beyond the t r a v e r s e of the
astroiclaut.
11-1 addition to the s te reometr ic film c a m e r a , the hand- held
levis is ion c a m e r a to be taken to the lunar sur face should a l so be
used to fullest extent practicable a s a scientific instrument. The
abundai~t video images obtained with the high-resolution mode
can be reduced in much the same way as the photographs from
the film camera . The television camera should be used to provide
a highly detailed r eco rd of the t e r r a in and geology in the imme-
diate v i c i ~ ~ i t y of the LEM.
-
Sarnpliilg tools, sample containers , a tool and sample c a r r i e r ,
a hancl magnifyiilg g lass , a hand- held flash light, and audio
communicatioi~ and recording equipment complete the l is t of
instruments required for the Apollo geological field investigation.
The c a m e r a s and field tools proposed a r e specialized adapta-
tions of coilventional c a m e r a s and geological field equipment.
Design studies are current ly in progress for most of the proposed
instruments. h program of field t e s t s has been initiated to study
the field procedures most suited t o the constraints of the luilar
missions, particularly the constraints imposed by the spacesuits,
the portable life support sys tems, and the charac ter i s t ics of the
LEM.

3. Charac ter i s t ics of the geologic field iilstruments
A. Stereometr ic film c a m e r a
The scielltific requiremellts of the Apallo geologic field
illvestigatiolls will be met by a c a m e r a which can produce s te reo-
scopic images 011 film that is sensit ive throughout the visible
spectrum, to objects rangillg in luminance from 25 to 2500 foot
lamberts . The images should 1) have a resolution of 100 lines
per mil l imeter ; 2) be focused sufficiently well that the maximum
diameter of any circle of confusion is . 02 mm; 3) have a field of
view of approximately 60'; a i ~ d4) be of sufficient photogrammetric
quality that maximum distance measuring e r r o r to objects 5 me te r s
distant i s + 1 percent when the images a r e properly oriented in v
existiilg f i r s t -o rde r plotters. Expasure should be uiliform a c r o s s
the image within 2 percent and the spec t ra l t ransmission of the
color f i l ters should be calibrated t o the response of the film in
o rde r to closely ~ n a t c h the CIE color matchillg functions.
B, Staff
A simple lightweight staff with a bracket t o mount the s te reo-
met r ic film c a m e r a is required t o hold the c a m e r a for taking
pictures. Ail easi ly read cliilometer and sun compass can be
incorporated into the head of the staff for estimating the orienta-
tion of the camera in the field. If it should prove feasible t o
incorporate a n R F trackiilg system into the LEM, the staff will
a l so se rve a s a base oil which to mount the transponder.
-
C. Ci~omon
A self - righting, tr ipedall y supported ver t ica l rod gimbled
to the support legs , s o as t o allow the automatic ver t ica l posi-
tioiliilg of the rod, is required to recover accura te orientation of
the s t e reomet r i c photographs. This device, when placed on the
ground and photographed, will give a t r u e ver t ica l orientation in
s t e reo models, and the t r a c e of its shadow on the ground will
provide accura te field orientation of the s t e r e o model recovered
from the photographs af te r the mission.
D. Televis ioi~c a m e r a
The Apollo Block II television c a m e r a should be used for the
collection of an extensive image r ecord of geologic features nea r
the LEM. The specifications required f o r scientific u s e of this
c a m e r a are:
(1) The c a m e r a is small , lightweight, and connected to the
t r ansmi t t e r by a co-axial cable about 30 m e t e r s long.
(2) C a m e r a charac ter i s t ics a re : 500 kc bandwidth; 0.625
f r a m e s per second; 1280 lines pe r f rame; 5-2500 foot
l amber t s illumination sensitivity; 3', 30' and 80' fields
of view, and minimum discrimination of 8 gray levels a t
J2 intervals.
(3) Simple c a m e r a orientation subsystems should be provided
to acquire data essent ial t o the interpretation of photo-
me t r i c data.
-
E. Sampling trowel
Samples of fine-grained surficial debris can be obtained by
a specially designed trowel having the following character is t ics:
(1) tough, chisel blade-front with a dis tal width l e s s than
the width of sample bag openings.
(2) flat bottom with slopiilg flanges on ei ther side.
(3) handle with malleable butt and overall balance compatible
with use a s a hammered chisel, Haiidle should be extei~d-
able to meet sterile sample requirements for biological
samples.
I;. Sampling tubes
The sampliilg of soi l profiles in fine debr is call be accom-
plished in many c a s e s by use of driven o r punched samplillg tubes.
Although telescopic data indicate there is a ve ry fine-grained,
porous surface layer on the moon, it is not cer tain how thick o r
coherent this layer is o r if it coiitaills coa r se fragments in
sufficieiit quantities to ser iously impair the use of sampling tubes.
G. Sampliiig hammer
Chipping of samples from large blocks of rock will require a
sarnpliiqg hammer. A modified geologist 's hammer will best meet
the requiremelits.
II. Sample scr iber /brush
The collection of oriented samples for s t ruc tura l , paleo-
magn?tic, and geochemical purposes requi res a rock sc r ibe r
-
which, for example, could be used to sc r ibe a shadow line on the
sample pr ior to photographing the sample in place. A sma l l
brush, which can be mouiited 011 the s a m e holder, will be needed
for removing dust f rom rock sur faces t o permit the i r c lose
examillat ioiz.
I. Field sample bags
The pr ime requirements for general geological sample
containers are that they can be eas i ly filled, rapidly sealed
against mixing, conveniently ca r r i ed , and capable of compact
packagillg in LEM/CM sample spaces.
J. Special sample con ta i~ le r s
I11 addition to the sample bags, the field geologic investigations
requi re special sample containers with the following character is t ics :
(1) Oile sample coiltainer should be capable of maintaining the
lunar atmosphere until samples are returned to the
receiving laboratory.
(2) One con ta i i~e r should be designed t o s t o r e the sampling
tubes taken on ally given mission.
(3) Opeiiings of contaiilers should be a s la rge a s possible for
e a s e of packing.
K. Tool and sample c a r r i e r
Efficient operations oil the lunar surface will requi re the
t ransport and ready accessibil i ty of the field tools and sample
containers and c a m e r a s . Studies and field t r i a l s conducted by
the U . S. Geological Survey and Maniled Spacecraft Center
-
indicate that a t r ipedal f r a m e with a long horizontal bar handle
described in a la te r section best meets the needs of lunar geo-
logical t r ave r ses .
L. Halld magnifyillg g l a s s
To 3id the astronaut in the discrimination and interpretat iol~
of undisturbed smal l fea tures of lunar mater ia l s , a hand magni-
fying glass should be developed having the following general
character is t ics :
(1) 5 to 10 power magnificatio~l
(2) optics and shape compatible with visibility and mobility
colzstraints on the astronaut,
M. Hand- held flashlight
A halld- held, bat tery powered flashlight to be ca r r i ed by the
astrollaut i s needed fo r the examination and photography of objects
partly o r wholly in shadow.
N. Audio communications equipment
Scientific evaluation of lunar surface operations in part
depellds on recovery of the astronaut 's descriptions of the surface.
Real t ime, mutual 2-way a l ~ d i ocommunication between the a s t ro -
lzaut on the surface, the astronaut in the LEM, and the mission
co~ l t ro l ceilter will be required for mission operations. These
commu~lications should be recorded in the i r e ~ l t i r e t y and t ime
coded for correlat ion with O T ~ G Y "scientific data. It is understood
that these requirements a r e met by the communication sys tems
current ly l-eing developed for Project A p ~ l l o .

4. Methods of analysis of the data
The images taken by the stereometric film camera will
permit photogrammetric, colorimetric and photometric analysis
of small parts of the moon's surface determined by the astronaut
to be of special interest. Detailed physical dimensions, color
and photometric properties of selected features and surficial
materials within about 5 meters of the astronaut will be obtained
from the images. 11-1addition, large scale topographic and geologic
maps of the landing s i tes and geologic t r averse paths can be com-
piled from the photogrammetric and photometric data obtained by
the s tereo film camera. The astroilaut t r averses with the s tereo-
metr ic camera will provide data comparable to a large number of
close- spaced Sunreyor landings.
A. Photogrammetry
Photogrammetric reductioil of the film camera data a s well
a s s tereo TV camera images will be accomplished by means of a
direct viewing coln puter controlled ailaly-tical stereoplotter.
The staff mouilted vertical base s t e reo camera requires a
f i rs t -order plotter to accommodate the following characteristics:
(1) Two matched lenses with s tereometric model capability
out to 5 m with + 1 percent measurement e r ro r . -(2) Direct viewing plotter capable of working at a base to
d is ta i~ce ra t io of . O l e
(3) Must be able to work with a vertical o r horizontal hase.
-
(4) Output will be in form of contour lines o r X Y Z
coordinates,
(5) Must be able to work with oblique photography with optical
axis ranging from horizontal to vertical.
(6) F i r s t -order stereoplotter precision in adjustment of
effective focal length from 25 mm through a range of
100 mm.
B. Photometry
Lumi l~a l~ce of ir~dividual resolu"ro11 elemelats of the lulaar
surface will be computed with referellce t o calibration charts on
the sampling hammer and the tool and sample ca r r i e r . Tne data
will be extracted from the photographs by microphotometric
measurement of the pr imary film records. Topagraphic mapping
beyotld the range of photogrammetric capabilities of the s tereo-
metr ic film camera will be extended by photocl i~~ometric methods
and by illterpolation of available orbital photographic data.
C. Colorimetry
Colorimetric measurements will be made by comparison of
the c o r r e s p ~ ~ d i n g luminance of individual image elements which
has been computed from pictures taken with a se r i es of color
fil ters. The method of data extraction will be the same a s for
photometry. Colorimetric measurements fo r each identifiable
element of the lunar scene will be transformed, where possible,
to CIE color coordinates.
-
D. Polarimetry
Polarimetric measurements will be accomplished by compari-
soil of luminance of iildividual image elemeilts which has been
computed from pictures taken with polarizing f i l te rs a t a series
of positions of the plane of polarization. Both the plane and amount
of polarizatioil of the scat tered sunlight can be obtained in this way.
The polarimetric properties of the lunar surface will be compared
with the color and other photometric properties in analysis of the
geology.
E. Geology
Analysis of the geology of each Early Apollo landing s i te
will be based 011 a syilthesis of the topographic, photometric,
colorimetr ic , polarimetric, textural and structural data extracted
from the photographs and television images, the field descriptioils
of the astronauts, and the lithologic, mineralogic, chemical, and
isotopic data extracted from the returned lunar samples.

5. Experimental procedures
A. Traverse operations
Ranger VIII photograph 570 shown in Fig. la illustrates a
part of Mare Tranquillitatis that is of the size accessible to foot
traverses by astronauts from a landed Lunar Excursion Module
(LEM) of the Apollo spacecraft or from any stationary vehicle on
the lunar surface. The geologic features and units shown in
Fig. l a and b are probably typical of this and other maria surfaces.
A11 example of several hypothetical traverses from the LEM,
arranged to examine features of special geologic interest are
shown in Fig. la. Such traverses should be planned in
advance, on the basis of photointerpretation, essentially to field
check the geology. The field-checking procedure is highly flexible,
and, if time becomes a limiting factor, the amount of detail
examined can be reduced from that shown to only a few of the
most critical features. If the landing is not precisely on the intended
site, a geologic map prepared from pre-flight illformation may
not be available. Even if the lailding takes place on a pre-chosen
site, many of the features seen on photographs may be incon-
spicuous and difficult to identify on the ground. In these latter
cases, the astronaut will have to solve as many of the geologic
relations as he can as he proceeds along his traverse and plan the
traverses as he goes along.
The representative traverses plotted 011 Fig. l a allow sys-
tematic sampling, photography, and description of each major

B. Sampling
One of the principal problems presented by a sur face covered
by a fragmental layer of the kind described above will be to select
appropriate sampIes fo r re turn t o Earth. With a wide variety of
rock fragments to choose f rom, the astronaut will be faced with
the difficult t ask of deciding what specimens best represent the
mater ia l a t hand. He will need t o est imate the relat ive abundai1ce
of different rock types in o r d e r t o select representat ive samples,
and, in addition, he will want to collect a s many of the iilfreque~ltly
occurriilg rock types a s possible, a s these will provide information
on the more distant, and possibly deeper, par t s of the moon.
111 cer tain respec ts the ]nodel described for the fine s t ruc ture
of the plains surfaces i s s imi l a r to t e r r a in on Ear th which has been
-
covered by deposits left by meltillg of a continental glacier. Like
glacial drift, the debris layer on the moon obscures the "bedrocky' I
in most places, is heterogeneous in character and irremlar in I
thickness, and contaills rock fragments of widely diverse illdividual
histories. Thorough study of such a layer in a local area either on the
moon or 011 the Earth can provide a great amount of information about
the geology and history of a broad segmellt of the planetary crust,
provided that the origill of the fragmeiltal layer is understood.
Failure to understand the nature and origin of the fine structure of
the moon, on the other hand, can lead to serious scientific misinter-
pretation and confusion. For this reason we regard the field geo-
logical investigatiol~ and the role of the astronaut as a trained field
observer to be fulldame~ltal to most of the lunar scientific illvestigations Y
to be performed in Project Apollo, and of paramouilt importance to the
success of later lullar missiol-ns,
Arrangement of materials arouild a fresh crater. --The----
problems of sampling in a typical landing site 012. the lullar plaii~s
can be illustrated with a hypothetical cross sectioil such as that
show11in Fig. 2. The oldest part of the surface in Fig. 2 is the
relatively level arca A; the youngest elemellt of the surface is the
fresh crater C,and crater B, subdued by erosion, is ii~termediate
i n age. The fresh crater may be collsidered to be a few meters to
a few tens of meters in diameter, in the size railge shown on the
/
-
be within t r a v e r s e distailce of the Ea r ly Apallo landing sites. The
crater is a l so l a rge enough s o that t he re is a good passibility that
the depth of the c r a t e r lnaybe g rea te r than the thickness of the impact-
shat tered blanket. Smaller f r e s h craters will provide informntlon
that is useful but l e s s c r i t ica l for geologic interpretation; l a rge r
fresh c r a t e r s should provide critical illformation but are fewer in
number and hence less apt t o be available fo r study.
Ideally the wall of the f r e sh crater might show, f rom the base
upwards, (1)the ma te r i a l which underlies the lunar plain; (2) the
full thickness of the impact -shat tered mantle, perhaps showing a
compositional profile and/or an alteration profile; and (3) a section
of the ejected mater ial . The Boor of the crater is apt to be under-
lain by breccia , and the l aye r i~ lg of the walls may be co~lcealed o r
obscured in part by slumping and creep. Moreover, the walls may
be s o s teep a s to be difficult of access ; the astronaut should sample
them if he can, but it is likely that he will be able only to photograph
and descr ibe chenl.
If the ru le holds t r u e that mater ia l s in the ejecta blanket a r e
deposited in r e v e r s e s t rat igraphic o r d e r , the upper surface of the
blanket will provide samples derived from deep within the c ra t e r .
Fo r example, if the sur face of the blanket is l i t tered with blocks of
rock differing in s ize , lithology, o r degree of alteration from rock
fragmei-its on the surrounding plaiil, the implication is that the plain
is underlain a t depth a t that place by that rock. 011 the other hand,
a deposit of a s h o r dust , s imi lar ly limited to the upper surface
-
and dis tal margills of the ejecta blanket, and differillg in composi-
tion, degree of alteration, o r o ther p r o p r t i e s f rom the impact-
shat tered blanket of the surrounding plain, would suggest that the
plain is the re underlain by granular mater ials , r a t h e r than rock.
I f the charac ter of the ma te r i a l s beneath the impact-shattered
blanket could be established in only one place, it would be a grea t
gain; with some luck the e a r l y Apollo m i s s i o l ~ s may establ ish it in
seve ra l places, on plaills of different ages. Samples of the mater ial
subjaceilt to the blanket, whether rock o r granular , a r e the most
meaniilgful that may be available on the lunar plains.
Profile sampling of ma t r ix mater ial . - - Even if no accessible
f r e s h craters penetrate to the base of the impact-shat tered layer ,
valuable evidence bearing ii-tdirectly on the nature of the subjacent
mater ia l , and direct ly on the origin of the fine s t ruc tu re of the
surf ic ial layer , can be obtained by study of sur face profiles. Walls
of f r e s h craters may provide such profiles. If they do not, sampling
the walls of t renches 10-50 c m deep, dug with the specially designed
trowel may be a method which has a good chailce of success in
surf ic ial mater ial with a wide range of g r a i i ~ s i ze and degree of
indurat ioi~, If the wall of such a t rench shows zoilal differeilces iia
co lor , texture, composition, o r other propert ies , the relat io~lships
should be described, photographed, and documeilted by samples cut
with the trowel s o a s to be representat ive of each zone. If there i s
no visible zonation, samples should be cut a t s ta ted intervals from
base to top of the t rench wall with equal c a r e for cornparisoil with
-
profiles of other ages and composition. The absence of zones
may be a s significant a s their presence.
Depending on the physical properties of the superficial
material , drive-tube samples may be e a s i e r o r more difficult to
obtain than samples cut with a trowel. I11 some mater ia ls the
drive-tube sampling method may not work, but under favorable
conditions the method provides ( I ) a suite of undisturbed o r little-
distorted samples representing the ent ire profile; (2) samples to
a grea ter depth than any reasonable dug trench, and (3) samples
that a r e ui~coi~tamiizated o r have a rniizirnum of contamii1ates
iiltroduced in the collection process, and (4) samples that can be
mailltailled in lunar eilvironmental coi~ditions by addition of gas -
tight jackets around the coring tubes. These advantages a r e s o
great that we recommend that three -drive tube sample devices be
ca r r i ed for t r i a l on the f i r s t Apollo missioi~. The apparatus i s
simple, and can be modified ear ly and quickly fo r use 011 la ter
Rock samples. - -Fragments of rock that l i t ter the surface
beyond the distal margins of the f resh ejecta blankets may be of
two origins- -(l)those that represent the local bedrock, and (2)
those foreign to the s i te , from extra- lunar sources o r other
places on the 1770011. The importance of obtaii1ing adequate
samples of the local rock, if any, has been s t r e ssed above. While
less cr i t ical , the foreign fragments may provide valuable preliminary
information about the composition of more distant parts of the moon.
-
If t he re i s a var iety of lithologic types, o r fo re ig l~ rocks,
the astronaut should es t imate the relat ive abundai~ce of each
type, and collect one o r a few smal l samples of each. A s the
lithologic var iety inc reases , the difficulty of estimatillg the
percelltage of each rock type inc reases , but the es t imates must
be made. If a la rge number of rock types are present , the
l imited sample re turn will make i t difficult t o bring back a
representat ive sample. Random sampling is justified only if
the fragmellts are s o a l te red o r coated that lithologic differences
are not readily apparent.
Fragments a few cellt imeters in diameter are adequate for
petrographic study and many o ther types of analysis. Fragments
5 t o 10 c m a c r o s s a r e i~eeded for special purpose analyses;
fragmellts l a r g e r than 10 c m probably must be broken fo r
packaging. Depending on the hardness o r toughness of the rock,
it may be possible to break chips f rom large blocks. It is v e r y
difficult, however, eve12 with the gravitational force on Ear th , to
break hard fragments in the 10-50 crn s i z e range embedded in
yielding granular mater ial ; such fragments will probably have to
be c a r r i e d t o a l a rge r block, if any, for use a s an anvil, o r taken
ent i re , o r not taken. a t all . I11 this , a s in eve ry other aspect of
the sampling process , the astrollaut must u s e judgment based 011
a full ul1derstanding of the problem.
Other things being equal, smal l fragments which may be
reaililp available aloilg t r a v e r s e l ines a r e preferable to chips of the
-
same rock broken from blocks, because of the saviilg in the
astronaut 's time. Similarly, there is no point in digging a
trench to expose a profile if the same profile is exposed in a
c r a t e r wall, o r in the depression, i f any, produced by the blast
of the LEM.
However they may be obtained, the most esseiltial samples
a t each site a r e those that bear directly on the major problems
of the lunar plains, namely, the charac ter and origin of the
material beneath the superficial blanket, and the processes
responsible for the fine s tructure of the surface. If only two
matrix samples can be obtained, they should include (1) a profile
from the oldest surface in the vicinity--probably the flatest,
darkest -colored surface, with the most strongly zoned profile- -
and (2) a profile from the youngest surface, which in most but
not al l cases , will be the outer slopes of the f reshes t c ra ter .
Other types of samples will have grea ter o r less value depending
on how closely they are ideiltified with geologic units, the relative
ages of which a r e known. The fact that the collecting t ime and
weight of samples will be fixed, places a premium on the
discrimination of the astronaut; this depends 011 his experience in
geologic field work in general, and the depth of his understanding
of the particular problems of the Apollo sites.
C. Exploratio~l t ime and astronaut mobility
The fundamel~tal constraints on achieviilg the goals of the
Apollo geologic field investigation a r e the limited number of man
-
hours available for scientific tasks and the limited mobility of the
astronaut in a spacesuit. The current est imates of the t ime
available for surface activities during ea r ly Apollo landing
average about 15 mail hours divided among 3 excursions of no
m o r e than 3 hours dura t io l~ each. These figures a r e largely a
fuilction of the capacities of the Lunar Excursion Module and
astronaut life-support systems. Such a division of t ime could
include one extravehicular excursion by one man and two excur-
sions by two men working together on the surface.
The mobility of the astronaut outside the spacecraft will be
governed by the mechanical propert ies of the surface, the
charac ter i s t ics of the spacesuit and the life-support sys tem, and
the charac ter i s t ics of the scientific gear that must be transported.
The distances that an astronaut can t r a v e r s e under various c o ~ ~ d i -
tions have not been determined with any degree of certainty,
although some est imates can be made. Allowing 0.5 hours for
e g r e s s , equipment checkout, aild ingress , the maximum useful
t ime for surface exploration duriilg an excursion would be about
2 . 5 hours. Tests conducted by the Manned Spacecraft Center of
the Natio~lal Aeronautics and Space Administration and by the
U. S. Geological Survey suggest that average geologic traverse
speeds (including t ime for description and other activities) over
rolling, loosely aggregated terrai l l may be 01-1. the o r d e r of 10 rn
per minute. Thus, maximum t r a v e r s e lengths on the o rde r of
1500 rn can probably be anticipated during any given excursion,
-
provided that sampling, photographic, and dc.;cr nprivc: uper,itio!lz,
can be carried out efficiently.

6. Astroilaut t ime requiremeilt synupsis.--
A. Pre-flight time
Pre-flight requirements on the t ime of the astronauts include
t ime for 1) training in geological field methods and 2) practice of
the geological field i~west igat ion in simulated Ear ly Apollo scien-
tific missions. T o date, individual astronauts have spent f rom
9 to 43 days training in geological field methods. About half of
the astrollauts have completed 34 days of training. Approximately
12 days additiollal training in geological field methods is planned.
An average of 12 days of practice of the geological field investi-
gation in simulated Early Apollo scientific missions is planned.
13. In-flight time
In- flight ( lunar surface) t ime required for the geological
field illvestigation is 2.5 to 15 man hours, depending on the i tnigh
of stay on the lullar surface alld the t ime require~nenrsof other
experiments. The maximum t ime that could be usefully employed
in the geologic field investigations great ly exceeds the t ime that
will be available in Early Apollo miss io i~s .
C. Post-flight t ime
Post-flight t ime of the astroilauts will be required for sci.en-
tific debriefing and for participation ill geologic alqalysis of the
returned data. I t i s expected that there wil l be a large range in
the extellt of participation of the astronauts in the post-flight
scientific al~alysis. To the extent that i t is possible for them to
-
participate, the astronauts should be considered co-investigators
in the geological field investigation. Up to several months of
astronauts' time would be appropriate and desirable for partici-
pation in the post-flight analyses. At a minimum, several days of
debriefiilg spread over a period of several months of data ailalysis
will be required.
-
The pre-flight requiremenro on the astronauts occur in two
phases, 1) training in geological field methods and 2) practice
of t h e lunar field geological operatioj~si n simulated
missions. In phase one, two-day field exercises about once
every three months are planned for the astronauts. These will
be selaeduled far the c&rn.lvenienceof individual astronauts or small
groups of astronauts. In part, the field exercises will be carried
out at localities where the geologic features correspond to features
that may be e~~countesed Other exercises will on the moon.
coilsist of brief participation in selected Geological Survey mapping
projects,
Phase two of the pre-flight requirements 012 the astronauts
i s divided into two periods. In the first period, prior to assign-
ment to a fligl~tcrew, the astrollauts should participate in field
tr ials and tests of the geologic instruments and contribute to the
evaluation sf the field use of these instruments. 117. the secoi~d
period, following assignmellt of crews to particular Early Apollo
missions, the crews should participate in full-scale simulations
and a dress rehearsal of the lullar geologic field investigatio~~ so
as to attain complete familiarity with all the scientific operations
and maximuln proficiency in carryi l~gout the mission.
-
B. Post - flight requirements
The post-flight participatioll of the astronauts in the field
geological investigatio~l will begin shortly a f te r the mission with
a thorough summary description and illterpretation of the geo-
logical features seen on the lunar surface. La te r , as s t e r e o
models, mosaics and topographic maps are developed f rom the
returned pictures, the astronauts will be requested to give a s
thorough an i l~ terpre ta t ionof the visual data as they can, in light
of the i r field experience a t each c a m e r a station. Those astroilauts
that participate fully a s co-investigators will probably wish to
participate in the preparation of geologic maps f rom the s t e reo
models and ill the analysis of the geologic history f rom the i r ow11
recorded field descriptions, the photographic data, and the resu l t s
ohtailled from the lunar samples . Some of the as t ronauts should
participate in thorough hand specimen description of the returned
lunar samples in o r d e r to co r re l a t e this data with the i r field
jmpressions and the photographic data.

1) Video tape recorders at each of the receivillg statiolls of
the Deep Space Net that will be used in the Early Apollo
Missioi ls alld at the Mission Control Center at the Manl~ed
Spacecraft Center.
-
2) Kinescope or other film recorders at the Missioil Control
Center and the investigators' room.
3) Video monitors at all stations listed in 1) and 2) above.
4) Audio recorders and monitors at stations listed in I),
2), and 3 ) above.
5) A photographic laboratory for processing, under carefully
coi~trolledconditions, the film returned from the stereo-
metric camera. Special control of processing will be
required for photometric calibration.
6) A sample receiving laboratory where certain preliminary
analyses and thorough hand specimen description of the
returned lullar samples can be carried out under carefully
controlled collditions. It is understood that specifications
for this laboratory already have been prepared.
7) An investigators' plotting room where the incoming video
signal and audio signal call be monitored and recorded.
This room should also contain an X-Yplotter driven by
computer which will record the position of the astronaut
in real time as calculated from telemetry received from
an RP tracking system 011 the LEM.
C. Data handling procedures
The investigators will require release of the data in the
fallowi~~gform from the Manned Spacecraft Center:
I ) One set of duplicate magnetic tapes of all video tele-
lnerry obtained from the lunar surface.
-
2) One se t of prime negatives obtained from one of the video
film recorders for al l video images obtained on the lunar
surface. The film record should be t ime coded. Six
copies of duplicate negatives prepared from the same
prime film negative will a l so be needed for distribution to
the iwest iga tors .
3) One complete se t of diapositive plates of a l l exposed f rames
prepared directly from the film negative obtained from the
s tereometr ic film camera .
4) Six high-quality f i r s t -generation duplicate negatives pre-
pared with s tep wedge photometric control from the primary
s tereometr ic camera negative.
5) Six copies of the audio te lemetry with a time code for a l l
descriptions of the lunar surface by the astronauts.
6) Detailed descriptions and photographs of each sample
obtained in the sample receiving facility during unpacking
and catalogiilg of the samples. Members of the i i~vest igator
team should participate in the hand specimen description
of these samples at the sample receiving facility.

MANAGEMENT PLANS
1. Responsibilities of the investiga tors
E. M. Shoemaker, a s principal investigator, will carry
overall responsibility for the geological field investigatioil in
the early Apollo maniled lunar lai~ding missions and will be
specifically respoilsible for the stereometric film camera, the
staff, and the gnomon. I-le i s also administratively responsible
for the development work and field testing of instruments to be
carried out uilder the Manned Lunar Exploration Studies section
of the Branch of As trogeology of the Geological Survey.
E. N. Goddard , as co- investigator, will be responsible for
the tool and sample carr ier , the hand magnifying glass and the
hand- held flashlight.
J. 13. Mack in, as co- investigator, will be responsible for
the samplillg tools, specifically the samplillg trowel, sampliilg
tubes, sampling hammer, and the sample scriber/brush. This
responsibility will iilclude liasoll with other investigators concerned
with sampling tools, particularly biologists collcerned with sterile
sampling.
H. H. Schmitt, as co-investigator, will be responsible for
the geologic al requirements and field use of the television
camera and the audio communications equipment.
A. C. Waters, as co-investigator, will be responsible for
the geological field requiremellts for the field sample bags and
special sample contaiilers. This responsibility will include liasoll
with other investigators concerned with the sample contaiilers,
particu l a d y geochemists.
-
The investigators will share equally i n the geologic
interpretation of the data each accordillg to his own special
fields of interest. E. M. Shoemaker will be respollsihle for
photogrammetric, photometric, colorimetric, and polarimetric
reductioll of the photographs and television images and will
supply maps and models portrayiilg this data to the other in-
ves tigators for geological analysis.
-
2. Operatillg budget
Funds required by the Geological Survey for development
work and field testing of the geological field instruments a re
available through existing contracts with the National Aeronautics
and Space Administration and through expected extellsions of
these contracts. 'The techrzical moizitors of these col~tracts are:
Doilald A. Beattie - Code MTL National Aeronautics and Space
Admillis tration Washington, D. C. 20546
Edward M. Bavii~- Code SNI Natioilal Aeronautics alld Space
Admi12istratioi~ Washington, D. C. 20540
John E.Dorllbach - Lunar Surface Technology Branch Space Environmellt Division Manned Spacecraft Center National Aerol~autics alld Space
Administration Houstolz, Texas 77058
I11 addition to the developmellt work and field testing of the
ii~struments, funds will be required for participatio~~ of the co-
investigators and for acquisition of special instruments for post-
flight analysis of the photographs and television images. Requests
for funds will be submitted by the co- investigators through their
respective institutions.
Funds are needed in fiscal year 1966 for purchase of the
direct viewing computer col1trolled analytical stereo plotter.
This illstrument will be required to verify the photogrammetric
use of the prototype stereometric film camera and to develop
the field procedures for optimum use of this camera.
-
