  • 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 .

    19

  • 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

    t r ave r ses .

    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

    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.

    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

    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.

  • Approximately twelve months is required for delivery of the

    analytical plotter after the purchase coiltract has been negotiated.

    The plotter should be ready early in fiscal year 1967 for use in

    reduction of photographs obtained from field trials with the

    prototype film stereometric camera.
