THE UNIVERSITY OF MICHIGAN 2914-1 -T INTRODUCTION On October 4, 1959 a third cosmic rocket was successfully launched in the Soviet Union, which put the first automatic interplanetary station in the world into an orbit that curved around the Moon. Equipped with a complicated complex of scientific apparatus, including photographic and television, the automatic interplanetary station passed near the Moon. The system of orientation of the automatic interplanetary station made it possibly to photograph that part of the lunar surface that is not visible from the Earth. It was necessary for the groups of soviet scientists, engineers, technicians and workers who created the cosmic rocket, to solve a number of the most difficult scientific-technical problems, which made it possible not only to put the automatic interplanetary station into the calculated orbit with the necessary accuracy, but to successfully carry out the projected program of investigation. Photographing of the far side of the Moon's surface began by special command as the Moon was being encircled and continued for forty minutes. Thus the first photographs of the far side of the Moon were obtained. Development of the methods of study of these photographs in order to detect the details of the lunar surface, compilations of the catalogue with descriptions of the particularities of the new objects, establishment of the coordinate relations and drawing of the map were carried out in Moscow by the P. K. Sternberg Astronomical Institute (project supervisor - Y. N. Lipsky) together with the

THE UNIVERSITY OF MICHIGAN - 2914-1 -T Central Scientific Research Institute of Geodesy, Aerophotography and Cartography (project supervisor - N. A. Sokolova). The same work was carried out simultaneously and independently in Pulkova by the Main Astronomical Observatory of the Academy of Sciences of the USSR (project supervisor - A. V. Markov) and in Kharkov by the Astronomical Observatory of the A. M. Gorkii State Universitory of Kharkov (project supervisor -N. P. Barabashev).

THE UNIVERSITY OF MICHIGAN 2 914 -1 -T RESULTS OF PROCESSING OF THE FIRST PHOTOGRAPHS OF THE FAR SIDE OF THE MOON Characteristics of the Original Materials and Photographs As is known, photographs of the far side of the Moon were obtained by the first soviet automatic interplanetary station (AIS) [1, 2] The photography was carried out by an apparatus having two objectives whose focal lengths and relative openings were equal to 200 mm and 1:5.6 and 5 mm and 1:9.5 respectively. The photographic apparatus was so mounted in the AIS that the optical axes of both objectives were parallel. A special orientating system, which included optical and gyroscopic counters, logical electronic devices and operating motors, made it possibly to aim the optical axes of the objectives at the Moon at the necessary time and to keep their orientation correct during the entire time of photographing. In photographing the far side of the lunar surface, it was naturally attempted to obtain at least the larger portion of that side in each shot, if not the whole far side. Obviously, this goal could be achieved only when the phase of the Moon (with respect to the AIS) was close to full moon. Moreover, the larger the part of the far side of the lunar surface that is illuminated by the Sun, the smaller the number of details of the visible side that is illuminated and can be photographed. However, in order to reliably decipher the photographs, it was very important to have them include portions of the well-known visible side of the Moon. Furthermore, it was essential that these known regions be situated sufficiently far

THE UNIVERSITY OF MICHIGAN 2914-1 -T away from the limbs and not at the disc's edge, where distortion of perspective is great. This last is important for several reasons. The presence of details on the photographs situated at a significant distance from the limbs, which are ordinarily visible from the Earth in the peripheral and libration zones in greatly distorted form with respect to perspective, would make it possible to increase our information concerning these objects. Not only the form of these details, but their structure, coordinates, etc., could be established more accurately. This problem cannot be solved by observations from the Earth. The study of specific particularities of the images of details in photographs transmitted from the AIS, the form and structure of which details have been well studied in photographs taken by earth observatories, would make it possible to more reliably interpret the objects situated on the far side of the Moon. The portions of the photographs with the indicated details could serve as a sort of "deciphering standard" for all newly revealed formations. Besides this a significant number of known objects, for which selenographic coordinates have been reliably determined from measurements carried out in the Earth observatories, should be present in the photographs transmitted by the AIS. This is important for making up a map of the far side of the moon.

THE UNIVERSITY OF MICHIGAN - 2914-1 -T Actually, if the photographs contain a large number of details whose coordinates are well known, it is possible to reliably oriente a coordinate network with respect to them and in this way to provide for the correct coordinate relations between the formations on the far side of the Moon. Also, a reliable connection between the coordinate network and the photographs make it possible to further determine the selenographic coordinates of the AIS during photographing. In order to satisfy the requirements indicated above, the moments of beginning and termination of photographing were so chosen that the AIS would be situated close to the line joining the Sun and Moon during this time. The Moon had to be visible to the AIS as an almost completely illuminated disc. Besides the far side of the Moon, this disc would include the western region of the visible hemisphere, which contains Mare Crisium, Mare Undarum, Mare Spumans, Mare Humboldtianum, Mare Marginus, Mare Smythii, Mare Australe, the craters Endymion, Neper, Condorcet, Petavius, etc. The conditions of illumination of the lunar disc during the photographing are analogous to those prevailing during near-full-moon phase for an observer on the Earth. The objective axes of the AIS camera almost coincided with the direction of the Sun's rays, which illuminate the lunar surface and for this reason the surface shadows become invisible and the contrasts between details become minimal.

THE, UNIVERSITY OF MICHIGAN 2914 -1 -T These last situations were taken into account in choosing the photographic film and in deciding on the conditions of transmission of images from the AIS to Earth. A specially prepared photographic film, 35mm wide, which can sustain processing at high temperatures, was used. This automatic processing, including simultaneous development and fixing with subsequent washing and drying of the film, was carried out on the AIS by a special miniature device which made possible the normal sequence of the indicated processes under the conditions of weightlessness. Likewise, the processing made possible the small dependence of the negative's parameters on temperature. Photographing was done using both objectives simultaneously so that details obtained in the large-scale photographs could be identified in the small-scale photographs which included the entire lunar disc, since the orientation of the camera for any two shots would be the same. Exposures, with automatically changing frames, were begun at command on 7 October 1959 at 6 hours, 30 minutes, Moscow Standard Time at a distance of 65, 200 km from the center of the Moon and were terminated on 7 October 1959 at 7 hours, 10 minutes at a distance of 68,400 km. Thus, the diameter of the image of the lunar disc was about 10 mm on the small-scale photographs, and about 25mm on the large-scale ones. In transmitting the photographs of the Moon to the Earth, the negative images of the film were transformed into electric signals by shining a light ray of constant brightness, produced by an electron-ray tube, through the film.

THE UNIVERSITY OF MICHIGAN - 2914 -1 -T The ray moved evenly and slowly across the film and upon reaching the edge, would quickly return to the original position. The light ray's motion produced a striped developing. Development of the entire frame resulted from the slow and even movement of the film itself. Having passed through the film, the light ray fell on a photo-electric amplifier, at the output of which was produced an electric signal having an intensity proportional to the change of transparency of the negative along the line of development. After amplification, the image signal proceeded to a modulator, which changed the parameters of the high-frequency oscillations emitted into space, to correspond with the change of the image signal. The form of modulation was so chosen that the influence of disturbances in the line of communication between the transmitter and Earth on the quality of the image would be decreased to a minimum. The image signals received by the Earth apparatus were recorded before demodulation by a magnetic recording device, and after demodulation by photorecorders and various apparatus that could be visually controlled. The intensities of these signals depended on the darkness of the corresponding portion of the negative images of the Moon, which were transmitted by the AIS. Thus, basically, these negatives, obtained by the AIS and transmitted to Earth by means of radio technique, served as the original material for studying the far side of the Moon.

THE UNIVERSITY OF MICHIGAN 2914-1 -T A photographic film that is sensitive to light, was situated in front of the screen of the electron-ray tube in the photo-recorders and was developed sideways and length-wise in a way analogous to that occurring on board the AIS. The brightness of the beam of the electron-ray tube changed with the intensity of the received image signal and as a result the Moon's image was elementally reproduced on the film. Besides this, such electron-ray tubes were used as kept the image on the screen for an extended period of time. Groups of the apparatus listed, carrying out parallel operations in specially selected regimes, received a complex of secondary negatives from each primary negative obtained on board the AIS. The photographs obtained from the magnetic recordings served as' important material in the scientific analysis. These photographs could be reproduced many times with different regimes of demodulation and registering apparatus, which made it possible to filter out a significant portion of disturbances in the line of transmission and to obtain essential auxiliary material along with the basic photographs. Naturally, this work could be successfully carried out only if the magnetic recording apparatus themselves introduced minimum amounts of distortion. The speed with which the magnetic tape was made to move was so stabilized that its motion resulted in not more than 0.1 part of an element of distortion of the image element. In order to decrease distortions introduced by the apparatus,

THE UNIVERSITY OF MICHIGAN 2914 -1 -T the image signals were recorded on the magnetic tape in frequency-modulated form.

THE UNIVERSITY OF MICHIGAN 2914 -1 -T The block scheme of the apparatus used for obtaining photographs from the magnetic recordings is presented in Figure 1. The recorders used in this scheme made it possible to obtain negative or positive photographs directly on a film or on large-size photographic paper. The form of a video-signal at the input of a recording apparatus for one line of development is shown in Figure 2. An auxiliary impulse, whose amplitude was kept constant and corresponding to the level of a white signal on the positive (black signal on the negative) was transmitted simultaneously with the image signal at the beginning of each line. The level of a black signal on the positive (white signal on the negative) was in fact determined by the fog in the film and characterized the minimum amplitude of the signal. The two indicated levels provided reference points for the, sensitometric measurements and made it possible to evaluate the relative darkness of the negative and the contrast of its details. On the basis of all these data, the optimum bands of the input and output filters, amplification coefficient of the video-signal amplifier, and parameters of the correction scheme were chosen in the apparatus complex (Figure 1.) However, in spite of the measures taken, we did not succeed in eliminating all disturbances. Some of the frames, transmitted over the longest distances, were received heavily veiled by disturbance bands due to the small ratio of signal-to-noise at these distances. Periodic horizontal noise bands, caused by the oscillation of signal intensity due to the rotation of the AIS, are noticeable on

THE UNIVERSITY OF MICHIGAN 2914-1 -T all the photographs. These oscillations of the signal level are caused by a break in the beam pattern of the station's antenna. So-called integral photographs (see photographs 1, 2, 26, 27 and 28) were obtained in this way. In some exposures the negatives on board the space station came out with increased or decreased general darkness. When the negatives were darker the number of details of the lunar surface that could be discerned directly from the photographs received on Earth was greatly reduced. Contact positives of the negatives received by the photo-recorders were used for studying the far side of the Moon. Every primary negative received on board the AIS and transmitted to Earth was represented by a number of positives from the secondary negatives recorded by several photo-recorders working in different regimes. Double negatives of all secondary negatives were also used. Both positives and negatives were printed on 35 mm film. The diameters of the large-scale and small-scale images of the lunar disc, obtained by thephoto-recorders on Earth, were equal to 25 and 10 mm, respectively. Besides these indicated materials, positives on photographic paper and on photographic film, which were prepared by cameras that reproduced the image from the AIS signals recorded on magnetic tape, were used. The diameters of the Moon's image on these positives were about 100 mm for the small-scale photographs and about 250 mm for the large-scale ones. After this, many repeated

THE UNIVERSITY OF MICHIGAN 2914-1 -T reproductions of all frames were made in specially arranged operating regimes of the apparatus, (i.e., so-called photometric cross sections were obtained) which significantly increased the deciphering possibilities. About 200 reproductions of all frames were actually used in this work. Disturbances, due to radio-engineering reasons, as well as defects related to the emulsion layer of the negatives on board the AIS, were present to a greater or lesser degree on all negatives and positives without exception. Radio disturbances in the form of bands, consisting of dots of various darknesses, are directed along the line of linear development across the film. The frequency and darkness of these bands are different for different frames. These defects in the images, that are not related to the conditions of radio transmission, led to the formation of bands of varying darknesses, which coincided with the direction of the frame's development. The bands on the primary negatives, which were exposed normally or somewhat insufficiently, for example frames 29 and 26 (see photographs 26 and 27 in this Atlas), are especially interesting. Besides this, there were defects in the form of dark spots (for example, frame 28) and bands (frame 26) in some of the frames due to damaged portions of the emulsion layer. A significant number of frames recorded by the apparatus for recording television images on a photographic film were noticeably elliptical, apparently due to the loss of synchronization between the mechanisms on board

THE UNIVERSITY- OF MICHIGAN 2914 -1 -T the station and on Earth. This ellipticity does not depend on the fact that the terminator line passes near the Moon's north pole, and by this causes a deviation from exact circularity of the edge of the lunar disc in the frames. The characteristic of the geometric distortions, occurring in the transformation of signals recorded on the magnetic tape into photographic images, was obtained by comparing the positions of the so-called reference points. Appropriate radio disturbance points situated outside of the images and clearly reproduced in all the photometric cross sections were used as reference points. If the images were reproduced without distortion, the reference points recorded at the beginning and end of any crosswise line of development would have to coincide upon juxtaposition of negatives of various photometric cross sections obtained from the magnetic recording of one primary negative. Moreover, the corresponding reference points situated in lines of crosswise development at the beginning and end of a frame would also have to coincide. Actually, geometric distortions occurred in both crosswise and lengthwise development. Measurements of corresponding distances between reference points on a large number of photometric sections showed that the distortions resulted in an average separation of 0. 2 mm between reference points in the crosswise direction and of 00 6 mm in the lengthwise direction when the images were 10 - 25 cm in diameter. Juxtaposition of the images of the lunar surface's details depicted in the different photographs shows that the AIS was rotating during the time of 13 _13

THE UNIVERSITY OF MICHIGAN 2914-1 -T photographing. By comparing the direction of lines in the various frames and knowing the time interval between the moments of exposure of these frames, the speed of rotation of the AIS can be determined. As a result of rotation of the camera, a significant portion of what the long-focal-length objective photographed of the far side of the moon was obtained in the large scale photographs. The pattern of overlapping of various frames is shown in Figure 3 below. The position of the Moon's image with respect to the edges of the frames shows that the camera's axis was tilted at an angle of about 0. 5 - 0. 7 from the AIS-Moon line. This inclination changes somewhat during the time of photographing. The errors, which this could introduce in determination of the coordinates of formations deciphered from the photographs are not large and were not greater; than"the errors introduced by the process of image transmission. The Methods of Increasing the Informative Properties of the Photographs Transmitted by the AIS The conditions of illumination of the lunar surface during the time of photographing, as indicated above, when the contrasts of details becomes minimal, made it quite difficult to recognize separate formations and their peculiarities and to pick them out from among the disturbances. Direct examination of the prints made it possible to discover a small number of the more distinct and characteristic details.

THE UNIVERSITY OF MICHIGAN 2914-1 -T Various methods were used to delineate the more indistinct details and to establish their existence. One of these methods was that of superposition of different frames. From several strictly coincident frames obtained under identical conditions, the actual details in them stand out while the random disturbances cancel out. Several types of superposing were used; simultaneous projection of several frames on a screen; projection of a positive on a positive print of another frame; obtaining "combination" prints from several negatives. Map-schemes containing several tens of details were compiled by this method in Pulkova and Kharkov. Most effective for delineating a large number of details was a special method of photometric cross sections used by the Moscow group, which wis worked out for this purpose and aided in raising the information properties of the available photographs of the far side of the Moon. Besides this the method of photographic masking was partly used in Moscow. The Method of Photographic Masking. When a detail having a wide variety of darkness is present in a negative, it cannot be successfully transmitted in a single printing on photographic paper because of its small photographic latitude. There was a wide range of darknesses among various parts in negatives of the far side of the Moon. Thus for example, on some normally exposed frames regions of the Soviet Range and Giordano Bruno's crater differed sharply in darkness from regions in Mare Crisium, Mare Spumans, Mare Undarum and Mare Foecunditatis.

THE UNIVERSITY OF MICHIGAN 2914 -1 -T At the same time the intervals between darknesses of the separate details in these zones were very small as a result of the indicated conditions of illumination. In order to decrease the great differences between the darknesses of the various parts of the negatives, the method of photographic masking which consists of the following could be used. A blurred positive (mask) is made from the negative to be analyzed. The image is blurred in the course of developing the mask by keeping its emulsion layer at a distance of several millimeters from the emulsion layer of the negative. A positive so treated develops before the required range of darknesses is attained, the limits of which are arrived at by trail and error. The obtained positive is then put together with the negative, with the positive being placed on the side of the light source. Obviously, photographic masking requires that the mask coincide exactly with the negative. Because of the presence of disturbance bands on the photographs of the back side of the Moon, the mask and negative had to be made to coincide that much more exactly than ordinary photographs and as a result, the method's effectiveness was decreased. The prints obtained on contrast photographic paper with the use of a mask increased the boundary contrasts between some details and made it possibly to clarify the configurations of a number of formations situated on the far side of the Moon. However the increase of contrast obtained in this way was clearly insufficient for showing up the greater number of formations in the photographs.

- THE UNIVERSITY OF MICHIGAN 2914-1-T The Method of Photometric Cross Sections. The most fruitful method turned out to be that of photometric cross sections which was widely used for deciphering the photographs of the far side of the Moon. It consists of multiple amplification by radio technique methods of the contrasts between details in the negative - not all of them at the same time but one by one depending on their photometric properties. This method was successfully realized due to the active help of radio operators with an apparatus that reproduced the negative images transmitted by the AIS from the records on magnetic tape. The parameters of the apparatus make it possible to record a known range of darknesses on the negative, which corresponds to a certain interval of brightness of the object. If the intensity interval of the image signals recorded by the apparatus is less than is permitted by its parameters, the intensities in the indicated interval can be correspondingly amplified. The smaller the intensity interval in the image requiring transformation by the apparatus chosen, the larger the amplification coefficient that can be used. The size of the interval was established by an amplitude limitation depending on the chosen photometric cross section. The maximum amplification coefficient permitted by the apparatus we used, equalled 100. We shall clarify this by an example. Let the curve ala2a3 in Figure 2 show the distribution of amplitudes along a line of the image transmitted by the AIS. The intensity io of the auxiliary impulse, having a constant amplitude corresponding to the level of a positive white signal, is taken as 100 o If we take two levels on the curve of amplitude distribution along a _ "" 18'....''' 8

THE UNIVERSITY OF MICHIGAN 2914-1-T positive image line corresponding to the lines ml and m2, and record only the interval within these lines, then all of the parts of the curve representing amplitudes of image signals that lie above m2, will be recorded as white and all parts representing amplitudes below ml will be recorded as black. After such an operation with all of the lines forming the positive images, a photometric cross section of the image was obtained. Moreover, only the contrasts of darknesses whose image signal amplitudes were situated between ml and m2 were amplified a known number of times. All of the zones of a negative transmitted by signals whose amplitudes are situated above the m2 level or below the ml level should come out white or black. The size of the amplification coefficient was determined by the interval of intensities or their corresponding darknesses, which was recorded in the image. The interval m2 - ml = am can be changed, thus changing the amplification coefficient. Besides this, it is possible to make "low" or "high" photometric cross sections depending on whether low or high intensities are included in the interval am. In other words, depending on where the interval limited by ml and m2 is imposed in relation to the curve of distribution of amplitudes along a line. If the interval am becomes so wide that it includes the curves of amplitude distribution along the brightest and darkest image lines, the resulting photograph shall be called "integral". Different photometric cross sections were used depending on which zone was to be deciphered. For -portions having little darknesses, for example the portion al in Figure 2, it is necessary to lower the height I of the photometric cross section enough so that the section 19

THE UNIVERSITY OF MICHIGAN 2914 -1 -T a1 is entirely included in the interval Am. The height of the amplitude of the center of the interval mz - ml, expressed into of Io, is called the height of the photometric cross section I. If very dark portions (white on the positives) are to be analyzed, a high photometric cross section is made, for example as for a3 in Figure 2, etc. The photometric cross section method turned out to be fruitful not only for deciphering completely unknown formations on the far side of the Moon, but also for identifying formations situated on the western edge of the visible lunar disc. The identification of some 100 details that have already been studied, is a criterion of reliability in a certain sense, of the newly revealed formations of the far side of the Moon. Photometric Cross Sections of Photographs of the Far Side of the Moon Photometric cross sections were obtained from all frames after all the materials had been studied in order to analyze the formations of the far side of the Moon. The quantities Am and I for each cross section of a given frame were chosen by trial and error depending on the darkness of the zone to be examined. It was frequently sufficient, in analyzing some portion, to obtain a photometric cross section not of the entire frame, but simply of the section to be studied. This took up less time and for this reason it was possible to make a larger number of photometric cross sections with a gradual change of the quantity I. As an example, we shall examine the photometric cross section of the large-scale frame No. 26. 20

THE UNIVERSITY OF MICHIGAN 2914 -1 -T The photometric cross section 26 - 2 (see photograph 3) is the integral print. The quantity I = 53 0/0 and the width of the interval am = 71 %o. A very large number of details are noticeable on this frame which are easily distinguished near Mare Crisium, Mare Marginus, Mare Smythii and objects more westward than these (the westerly direction is the same as that in which the longitudes increase). Many separate dark formations apparently of the type of crater seas or cirques are noticeable in the Mare Australe region. Many formations that are visible from the Earth in the peripheral zone, such as Endymion, Mare Humboldtianum, Gauss, Hanno, Plutarch, etc., are also recognizable. However, the region at + 50 latitude and 1200 longitude poorly relates particularities of the lunar relief. The same can be said with regard to the regions situated to the northwest of Mare Humboldtianum, near Giordano Bruno, to the southwest and south of Mare Australe, etc. The boundaries of Mare Marginus and Mare Smythii are not sufficiently clear in the examined frame. The difference in brightness between Neper (in which the central hill is very noticeable) and Mare Marginus is not noticeable, etc. The next photometric cross section is 26 - 3 (see photograph 4). Here the quantity I, which represents the "height" of the cross section, remains the same (530o) although the interval am is now taken at 63 (o (instead of 71 0o). This photograph is also an "integral" one but its appearance is somewhat changed. Some of the details near the Soviet Range are lost, but the discernibility of

THE UNIVERSITY OF MICHIGAN 2914-1-T the northern part of the Mare Smythii and adjacent formations is increased. The details at 3 = -25 and X = +70 have become a little more visible. The regions of Mare Marginus and Mare Humboldtianum remain almost the same for the better, while visibility around Endymion is worse. The photometric cross section 26 - 1 (photograph 5) was made with a higher I equal to 609o and a smaller darkness interval Am = 55 q9o. The appearance of the photograph changed considerably this time. It turned out that a significant portion of the image was darker than the upper limit of the interval of recorded darknesses and thus became "white". It was enough to lower the interval m2 - ml = 8m but 8 O/o in comparison with the cross section 26 - 2, when the Soviet Range region, the entire region northwest of Giordano Bruno and west of the Mare Humboldtianum became "white". The difference between the brightnesses of the formations north of Mare Marginus was revealed more clearly - some of them turned out to be above m2 and became "white" (differences of 8 - 109o between the intensities of the recording signals were not so sharply revealed in the photometric cross section photograph 26 - 2). The formations situated on the western boundary of Mare Humboldtianum, to the north and northwest of Mare Marginus became more clearly defined. The southwestern and southern boundaries of Mare Smythii were visible a little better. Many formations between Mare Smythii and Mare Australe which before were a little lighter than the general background, and now became "white", became clearer. The contour of the Mare Australe became a little better, many details situated in it became 22

THE UNIVERS7ITY OF MICHIGAN 2914 -1 -T lighter than the floors of Mare Smythii or Mare Marginus which are seen as very dark formations on the photograph. The photometric cross section 26 - 4 (photograph 6) was obtained for the values I = 35qo and LAm = 719o. The large role played by the "height" of the cross section becomes immediately evident if we compare this photograph with 26 - 2 (I = 53 /o, am = 719o). The clarity of most of the details in photograph 26 - 4 is sharply reduced but it reveals that the northwestern part of Mare Smythii is darkest. It is noticeable that the bottom of Neper is lighter than the central part of Mare Marginus. The boundary of the darkest northeastern part of Mare Humboldtianum is delineated. The boundaries of formations on the peripheral eastern zone became more clear. The photometric cross section 26 - 9 (photograph 7) is the highest: The photograph is obtained with I = 70b0and /m = 107o. The amplification coefficient was close to 40 in this case. Thus the contrasting differences between the "gray" details reproduced by signals having intensities of 65 to 75/o of the intensity of the mentioned auxiliary impulse, were amplified 40 times. As is evident from the photograph, the great majority of formations were recorded by signals of less than 65Io intensities and for this reason, they naturally came out "black". As a result the following formations disappeared against the "black" background: Mare Humboldtianum, Mare Crisium, Mare Spumans, Mare Smythii, Mare Australe, the Lomonosov, Joliot-Curie, Edison, Maxwell craters and others. 23

THE UNIVERSITY OF MICHIGAN 2914-1 -T An area in the + 600 latitude region and separate parts of the Soviet Range turned out to be recorded as white without amplification of the contrasting differences of details. The reproduction regime of this photometric cross section was so chosen that it facilitated the analysis of areas near Giordano Bruno, in the Soviet Range region and areas close to these in intensity. New details were discovered in the photograph. The boundaries of the circular formations of Giordano Bruno were noted and the non-uniformity of its internal structure was revealed. A white spot, apparently a raised portion is noticeable to the southwest of this formation. The bright white spot surrounding Giordano Bruno in the integral photograph and in previous cross sections, fell apart into separate details. Only separate details of the light area 701 at the north were recorded on the "white" level (3 = + 630, X = + 1000~, see Map of Far Side of the Moon). On all the other photographs, this region appeared as a plain white spot with practically invisible details. Beside it (/3 = + 570, X =+ 1020) an almost round formation 666, somewhat resembling Mare Humboldtianum in details appeared relatively clearly. This detail was unnoticeable in the other photometric cross sections and in the integral photographs. The uneven internal structure of detail 666 was revealed. A light, round formation is easily noticeable against its dark background in its eastern part. Since the value of /m = 1 0o during recording of the photometric cross section 26 - 9, those details situated near one another and 24

THE UNIVERSITY OF MICHIGAN 2914-1 -T appearing "gray" on photographs (neither "white" nor "black") are differentiated with respect to the appropriate amplitudes by not more than 10qo. Thus the light spot situated in the east of formation 666 almost coincides, with respect to intensity to the portion surrounding Giordano Bruno and to some parts in the Soviet Range region. This cross section well reveals formation 687 (f3 = + 530, X = + 1170) which is not noticeable in previous photographs and which apparently resembles 666. Small light spots are noticeable in the dark bottom of this crater-like formation. Separate details which differ in brightness more than by 100o are likewise revealed in the Soviet Range region. The next photometric cross section 26 - 10 (photograph 8 was made with I = 60%0 and 8m =1 fo (i. e., with amplification equal to that of the foregoing cross section). In this photograph quite large regions went over into the "white" sphere, although from 9 and 26 - 10 differ only by 10~o with respect to I. A trace of a ray, going from Giordano Bruno to the Soviet Range and crossing through about the center of the circular formations 640 (I = +280, X = 1080) and 638 (f3 = + 250, X = 1090) begins to be noticeable in the latter photograph. A significant number of details in the region bounded by the coordinates f = + 10 - + 300 and = + 110.1300, become noticeable in this section, while they are hardly so in others. A number of bright light spots, part of which turned out to be recorded at | the "white" level, stood out noticeably in the Soviet Range region. Formations

THE UNIVERSITY OF MICHIGAN 2914 -1 -T 701, 666, 687 and others almost disappeared on the light background. The traces of a number of details in the south became clearer. The contour of Mare Australe began to be visible. A region that differs little in brightness from the region bounded by the coordinates 3 = + 100, + 30~ and X = + 110, + 1300 is adjacent to this Mare. Mare Marginus, Mare Crisium, Mare Smythii and a number of other details continue to be recorded as black. The contours of Mare Humboldtianum, Tsiolkovskii and others became barely noticeable. The photometric cross section 26 - 11 (photograph 9) was made with an amplification coefficient of about 40 and a value of I = 500/%. Lowering the height of the cross section by another 100/o again greatly changed the appearance of the photograph. Some of the previously visible details disappeared and the visibility of others improved. The ray going from Giordano Bruno to the Soviet Range showed up sharply. The contours of the Joliot-Curie, Edison, Lomonosov and Maxwell craters showed up more clearly. Sections near Mare Australe that were reproduced on the "gray" level by signals differing not more than 10fo in intensity became differentiated. Areas within Mare Australe that differed less than 1 00/o in intensity from areas to the north and east of it, became noticeable, and so forth. Even a greater portion of the surface turned out'white" in the photometric cross sections 26 - 12 and 26 - 14 (photographs 10 and 11), which were likewise obtained with an amplification coefficient of about 40 and with heights of 40 and 26

THE UNIVERSITY OF MICHIGAN 2914-1 -T 35, respectively. A comparison of the photographs shows that there is a brighter detail (noticeable in 26 - 12) among the structural particularities of the Joliot-Curie (i. e., it has an amplitude about 1 00/o greater than do the details revealed in 26 - 14). A round dark spot, situated in the southeastern part of Joliot-Curie is visible in 26 - 14 and is apparently also a crater. The differences in intensity of regions adjacent to Mare Marginus, Mare Smythii, of many details within Mare Australe, etc., can be evaluated. Besides the photometric cross sections of frame No. 26 that are listed here, a significant number were prepared from separate parts of the frame, which needed analysis of very fine differences of intensity. Most of them were prepared with an amplification coefficient of about 100 and with gradual transition with respect to height. Thus, for example (photographs 12 through 22) I = 75%and m = 40/0 for the intensity of 26 - ld I = 76'o and Am = 40/ for the intensity of 26 - 2d I = 77fo and am = 40/0 for the intensity of 26 - 3d I = 78qo and am = 40/0 for the intensity of 26 - 4d I = 798o and am = 400 for the intensity of 26 - 5d I = 45c/o and am = 40/0 for the intensity of 26 - 6d I = 46% and am = 4% for the intensity of 26 - 7d I = 47Qo and am = 40/o for the intensity of 26 - 8d I = 48qo and Am = 4'?o for the intensity of 26 - 9d I = 524o and Am = 4'o for the intensity of 26 - 10d I = 580/0 and am = 4qo for the intensity of 26 - 13, etc.

THE UNIVERSITY OF MICHIGAN 2914-1 -T The following parts of frame 32 are given in photographs 23, 24 and 25 in the same order I = 15%/, m = 70qo for the intensity of 32 - 5d I= 20/ob, Am = 70'o for the intensity of 32 - 6d I =22'o, am = 7 00/ for the intensity of 32 - 7d The terminator line in these photographs passes through the upper part of the picture. A group of craters is clearly noticeable in the upper righthand corner. The proximity of the terminator emphasizes the relief of the formations. The appearance of the craters is close to that obtained in photographs made from the Earth. Integral photographs of frames 29 - 2, 31 - 2, 26 - 0, 28 - 1 and 28 - 3 are shown in photographs 1, 2, 26, 27 and 28 as examples of the photos obtained by the AIS. Some 200 photometric cross sections whose regimes were chosen by trial and error, were used in the process of work on the photographs of the far side of the Moon. The parameters of some photometric cross sections are presented in Table 1. 28

THE UNIVERSITY OF MICHIGAN 2914-1 -T Analysis of the Material As already indicated, photographing of the far side of the Moon continued for 40 minutes during which time the selenographic coordinates of the AIS changed but 0.4~ in latitude and 0. 50 in longitude. For this reason it was decided to construct only one coordinate network and reduce all photos to the scale of this network. The resulting errors in the coordinates of the lunar formations are much less than the errors caused by geometric distortions of the photos. A scale of 1:10, 000, 000 was chosen for the map of the far side of the Moon, and all the photos were reduced to approximately the same scale. A circle, 35 cm in diameter and somewhat cut off at the north due to the Moon's phase, served as the basis for transforming the small-scale photos. The edge of the lunar disc did not appear on all the photometric cross sections of every frame. In order to convert these sections correctly, reference points were used. Either the integral photograph or the lowest photometric cross section in which the outline of the lunar disc was clearest was first established in the photographic converter. By changing the projection scale and the inclination of the screen we sought to make the edge of the disc fit into the mapped circumference. The reference points were transferred at the same time. In transforming all of the subsequent copies of a given frame, the clearly recognizable portions of the lunar disc and the transferred points served as reference points. We succeeded in somewhat decreasing the geometric distortions of the photos in this way. 32

THE UNIVERSITY OF MICHIGAN 2914-1 -T The southern and southeastern portions of the lunar disc and clearly visible large objects (Mare Crisium, Mare Humboldtianum, Mare Marginus, Mare Smythii, Lomonosov, the Moscow Sea, Tsiolkovskii) that were transferred from the small-scale photos were used as reference points in transforming the large-scale photos. Transformation began in the same way as with the small-scale photos - from a photometric cross section in which the edge of the lunar disc and some of the above-mentioned objects were most clearly shown. The image of the disc's edge and the reference objects were used partly in transforming the subsequent photos, but the disturbance spots were the main reference points, and these were transferred to the initial negative when the first print was transformed. In the process of transformation the small-scale photographs were enlarged about 3.5 times and the large-scale ones about 1.4 times. Thus the total enlargement of the transformed photos over the originals was about 35 and 14. Examples of transformed photos of frames 29 (small-scale) and 26 (large-scale) are given in photographs 29 and 30". The appearance and quality of the images of quite small objects is evidence not only of the good quality of the photographic emulsion used for obtaining the orignial negatives and of the development process, but also of the high resolving power attained in the television transmission of the images. * For technical reasons, the image of the Moon in photograph 29 is magnified about 28 times. II_ _ _ __ ~33

THE UNIVERSITY OF MICHIGAN 2914 -1 -T Analysis of the formations of the far side of the Moon was carried out from the transformed photographs. In doubtful cases, images of the respective objects were studied from the photographic films obtained from the magnetic recordings simultaneously with the prints on photographic paper. First, the discernible details in prints of all of the photometric cross sections of each frame were outlined on those prints where they appeared most clearly. Then the reference points, all of the outlined objects and the edge of the lunar disc were transferred to tracing paper from the first print. The reference points on the tracing paper were matched up with those on the other photographs in transferring outlined details from the latter to the former. In this way all of the formations discerned on the photos of all the photometric cross sectionswere collected on one tracing paper. These composite tracings, compiled for all frames were superimposed one on another. Alignment, was effected according to the more clearly delineated objects which appeared on all the frames (the Tsiolkovskii, Kurchatov, Lomonosov, Giordano Bruno, Jules Verne and Neper craters, Mare Crisium, the Moscow Sea, Mare Australe). On top of these was put a clean tracing paper onto which were transferred formations outlined on not less than two frames, the outer edge of the lunar disc and the reference points of each frame. As the objects were traced the second time they were numbered and registered in the catalogue. Three digit numbers were used to identify the formations, beginning with 101. Besides the number of the formation, the numbers of the frames in which ____________________ ~34 ________________-.I

THE UNIVERSITY OF MICHIGAN 2914 -1 -T it was found and the numbers of photometric cross sections were included in the catalogue. A descripiton of what was seen on the photographs was also recorded - whether the formation is light or dark - from which frames were the position, form and dimensions of the object taken. Furthermore, the object's position was transferred to the tracing paper as a rule from the frames having the least geometrical distortion, while its form and dimensions were taken from the frames in which it was most clearly delineated. The tracings compiled in this way were corrected again in the process of which the correctness of the outline of each formation was established by checking against the photographs of the necessary photometric cross sections of the corresponding frames and against the other materials: the uncertain formations were removed and others drawn in, the outlines of the formations were made more exact, the degree of certainty was more accurately determined and the object was described. After corrections the tracing was used for further work. All of the outlined formations are divided into three categories. Formations that are noticeable on three or more frames and are clearly delineated as well as showing all identified objects of the peripheral and libration zone are put into the first catagory. The position and outlines of these formations are reliably established. Formations that are noticeable on only two frames, or on many frame but not too clearly, are put into the second category. Their outlines will be made more exact from photographs of the far side of the Moon taken at other phase 35 S..~~~~~~~~~~~~~~~~~~~~~~~~~~~

THE UNIVERSITY OF MICHIGAN 2914 -1 -T angles. Those formations which had unclear outlines or were decipherable only on one frame, fall into the third category. Besides the formations of the far side of the Moon, some 100 formations situated on the visible side in the zone between 70 - 900 western longitude were identified with objects visible on photographs taken from the Earth. Several clearly visible objects of the Moon's visible surface towards the east from the 700 meridian were likewise transferred to the tracing paper for coordinate correlation. A coordinate network in an external perspective projection was computed and constructed according to the AIS's known selenographic coordinates and its distance from the Moon during photographing. In agreement with the material available, the formations situated on the visible side of the Moon were di'awn on this network. Then the tracing paper with all of the formations discovered from the photographs was superimposed on the coordinate network in such a way that identical objects on the tracing paper and on the constructed projection coincided best. The coordinate network was then transferred to the tracing paper. The exactness of coincidence can be evaluated from the differences between the coordinates computed from the tracing paper and those determined from Wilkins' map t33. The values of these differences are presented in Table 2. The values of differences presented in the table are of random character and result from both the geometric distortion of the photographs and errors in identifying lunar formations on them. In drawing up the map, the position 36

THE UNIVERSITY OF MICHIGAN 2914 -1 -T of Endymion and of Mare Humboldtianum were taken from Wilkins' map and thus formations on the far side of the Moon that are close to these, particularly a group of craters near the north pole, were displaced.

If we do not count objects 725 and 726 and 729 situated near the pole, the average differences are 20 in longitude and 1. 50iin latitude, which means that the average error of determination of coordinates of formations on the far side of the Moon comprises about 1.40 in longitude and 1.10 in latitude. The final map of the far side of the Moon was drawn as an equatorial orthographic projection with the central meridian at 1200 west longitude. In order that the map be easily seen at a glance and at the same time be easy to read, a scale of 1:1,000, 0000,was chosen. Thus the diameter of the lunar hemisphere on the map was made equal to 34.76 cm. The coordinate network is drawn through every 100 in longitude and latitude. The materials used for compiling the map of the far side of the Moon were Wilkins' map for the visible side of the Moon and the tracing paper containing the formations derived from the AIS photographs and their descriptions in the respective catalogues. The following arbitrary designations are used in connection with the results of analysis: ojbects of the first category are outlined by a solid line; objects of the second category are outlined by a broken line, and those of the third category by a dotted line. Dark formations are shaded in. A special arbitrary symbol is used to designate light colored formations that represent a complex of smaller formations (for example the Soviet Range). The rays seen in several photos are represented by broken lines. A heavy broken line indicates the limit of visibility from the AIS _.,,,,,, ~ 39

THE UNIVERSITY OF MICHIGAN - 2914 -1 -T during photographing. Each of the formations deciphered from the photos is numbered the same on the tracing paper as in the catalogue. Objects which were named are so labeled along with the number. The map of details of the lunar surface that was obtained in the described way was compared with analogous but less detailed maps and schemes obtained independently in Pulkova and Kharkov. Almost all the details discovered by the latter groups coincided with the reliable details of the map published here. Differences were noted only in the outlines of some of the formations. A catalogue of the discovered details and an Atlas of the Far Side of the Moon are presented below. The catalogue contains the numbers of the objects by which they are identified on the map and their given names. It also contaifis a list of the frames and their photometric cross sections used to decipher each detail, - descriptions of what was seen on the photographs and descriptions of the separate objects and their coordinates. All of the objects are listed in order of certainty. First are listed those of the first order of certainty. These are 252 in number. Then are listed the 190 formations of the second category and finally the 57 formations of the third category. The last require verification. The Atlas includes integral photographs and photometric cross sections of the photographs of the far side of the Moon along with a map drawn in an equatorial orthographic projection with the central meridian at 120~ and to a scale of 1:10,000,000. 40

THE UNIVERSITY OF MICHIGAN - 2914 -1 -T The map presented here was compiled on the basis of studies of the first photographs of the far side of the Moon obtained by the Soviet AIS.
