(Paris, L'Humanite, 30 Aug 58) Preliminary Results of Sputnik II Cosmic Ray Measurements A complete translation of the article, "The Measurement of Cosmic Radiation by an Artificial Earth Satellite," by S. N. Vernov correspond- ing member of the Academy of Sciences USSR, N. L. Grigorov, Yu. I. Logachev and A. Ye. Chudakov, follows: "The preliminary results obtained by apparatus installed in Sputnik II are presented in the current article. "Two similar instruments for the desired recording of variations of the intensity of cosmic radiation were installed in the satellite. Both instruments were completely independent, and thus the coincidence of their readings provided a check on the proper operation of the apparatus in flight. "Each of the instruments consisted of a charged particle counter with an operating length of 100 millimeters and a diameter of 18 milli- meters. The average amount of matter surrounding the counter was 10 gram/cm2. The operating voltage of the counter (!E00 v) was provided with the aid. of a semiconductor converter, which was fed from a battery with a voltage of 6 1/2 v.

"During the flight of the satellite in its direct spiral over the territory of the Soviet; ?Jn.ion (the. motion from south to north), its flight altitude over the surface of the Earth remained practically un- cbanged (225-2)10 kilometers). During its motion in the reverse spiral, the altitude of the flight grew approxiratcly from 350 up to 700 kilo- meters with the decrease in latitude from 65? N to 400 N latitude. The relation of the intensity of cosmic radiation of the reverse spiral in relation to the intensity in the direct spiral at one and the same geo- graphic points gives the relative increase of intensity at the expense of the difference in altitude [see Figure 1. of original article). If the relationship of cosmic ray i:ntensity to altitude were one and the same at different. altitudes, then Figure I would give this relationship. "The change in intensity of cosmic rays in relationship to altitude beyond the limits of the atmosphere can be due to at least three effects: (1) the increase of intensity at the expense of the decrease in the screening action of the Earth.; (2) the increase of intensity because the lessening of the Earth's rnagnet.ic field leads to a decrease in the generation of the energy of particles which can penetrate through the Earth's magnetic field; and (3) the change of the'albedo of cosmic radiation. The discovered altitude rel.n11oaship can be explained by the calculation of only two primary effects. "The measurements conducted of cosmic ray intensity during the flight of the satellite at many direct, :spirals makes it possible to construct lines of equal i.ni;c:nsity of this radiation. (isocosms). "In Figure 2, isocosms for three iral.ues of the velocity of light are presented: 18, 27 and 36 impulses per second. "As can be seen from Figure 1_, experimental points, best of all, lie on the geographic parallels. In the equatorial region, Simpson [J. A. Simpson, K. B. Fenton, .:r. Katzman and D. C.

Simpson, Report o:.-r the Conference at VarennaI discovered that the lints of minimum cosmic ray intensity ("cosmic equator") did not coincide with the geomagnetic equator. In -onnection with this, the rece:1p`, of data concerning the distribution of cosmic ray intensities over the whole world is of great interest.

Yu. Zigel. "In r_?orlnection with the creation of artificial Earth satellites it is of interest to determine theoretically various orbits which their motion could fo.ll.ow. "Because the masses of artificial earth satellites are negligibly small in comparison with the masses of the Earth and the Moon, their motion in the Earth.-Moon system may be considered. as the motion of a body with a negligibly Small mass in a restricted three body problem. On the other hand, for a satellite of arbitrary mass, including a mass as small as desired, the particular three body problems analyzed by Lagrange are applicable, "By deaignating the mass of the Earth with. M, and the mass of the Moon with m a:c,d assuming M/m = 81, let :is find the position of the libration points in the particular case of Lagrange. for the Earth.-Moon system.

"The libration. points In the special Lagrange case have the property that a body (satellite) located at any of these -points with a zero' re- lative velocity will remain there forever conserving a permanent con- figuration with respect to the other two bodies (Earth and Moon). We should keep in mind that the libration points will. be motionless only in a rotating system of coordinates, the origin of which will coincide with the center of gravity of the Earth.'-Moon system and the abscissa axis will pass through the centers of both of these bodies. "The collinear libration points are points of unstable equilibrium and therefore satellites located at these points will .lave the equili- brium position at the least di.sp]acement. and may move far away from the libration points. It is true that by means of reaction engines it will be possible to return. the satellite to th; initial position and in this way secure an "artificial stability."

The full text of the article, excluding figures 1 and 2 and tables 2 and 3, entitled "Some Results of an Investigation of the Moor's Figure for Determining Ito Exact Coordinates," which appeared in the IGY Information Bul.l.etin of the Academy of Sciences Ukrainian SSR, is presented here: Among the great number of investigations according to the IGY program, investigations with the use of astronomical methods and observations are far from last place. Such investigations include, as is known, photographic observations of the Moon for determining its exact coordinates. The study of the orbital motion of the Moon, as well as other celestial bodies, makes it possible in many cases to solve certain problems of a geophysical char- acter.. The motion of the Moon among the stars from the viewpoint of celestial mechanics is steadied with sufficient accuracy. This makes it possible to compare the observed coordinates of the Moon with coordinates computed on the basis of gravitation theory and the differences between them are attri- buted to other, nongravitational, reasons. At present, it can be stated with certainty that among the latter there are even reasons of a geophysical character. Not going beyond the limits of the theme of this article, we shall briefly enumerate those problems of a geophysical character for whose solu- tion it is necessary to enlist the observations of the Moon: 1. Study of the nonuniformity of the Earth' rotation. 2. Determination of ephemeris (Newtonian) time. 3. Determination of the dimensions of the geoid and solution of problems of higher geodesy. 4. Study of the movement of the continents..

Thu study of the orbital. motion of the Moon, us we:L:L as the study of physical .l.ibrution, always rests on the question concerning the figure of the Moon. The fact is that during observations measurements of the limb of the lunar disc, whose form changes relative to optical. libration, are always being made. This change in the form of the limb of the lunar disc adduces to the fact that the center of the figure of the Moon, found from measurements of the limb, does not always coincide with the center of the lunar mass. Thus, a comparison of observation results with theory, with- out taking into account the relative position of the center of mass and the center of the figure of the Moon, is incorrect. This circumstance results especially from the relation of the radius of the Moon to libration in latitude, a fact which is confirmed by an entire series of heliometric observations and indirectly by other observations. The relation of the radius to libration in latitude in the first approximation, is con- sidered linear: R = Ro t bpo where Ro is the radius when (~ o = 00; the term b 1 0 expresses the libration effect in the radius. f (1) A summary of determinations of the coefficient b is given in Table 1.

In addition, there is a basis to as:,7mnc that it. differs for the eastern and western limbs of the Moon. Thus, the study of the lib:ration effect and its influence on the relative position of the center of the figure and the center of the mass of the Moon is an inte:tzesting and timely problem. In the Main Astronomical Observatory of the Academy of Sciences Ukrainian SSR, investigations of the figure of the Moon are conducted under the supervision of A. A. Yakovkin on photographs taken by the 400-mm astro- graph (D - 400, F = 5500 mm) with the aid of an automatically moving plate holder (Fig. 1). In this article, certain results of processing of the first series of photographic observations 1955-1957 are presented. More than JCO negatives suitable for measu.rrements were selected for analysis., Data on them are given in Table 2.. Columns 4 and 5 of this table contain topocentric values of optical libration in longitude and latitude. Column 6 gives the radius of the Moon taken from Ast,ronomicheskiy Yezhegodnik =SSR (Astronomical Year- book of the USSR) and burdened by the parallax. Column 7 gives the charac- teristic of the photographic density of the negative. In Column 8 the measured limb of the Moon is indicated by Z (western) and V (eastern). The method of ob,_e~ u?ations with use of the automatically moving plate holder was described by us in an earlier work [ 5 1. In processing photographs of the Moon, the detezm.ination of the scale of the plates plays an important role. For this purpose, we especially investigated the relation of the scale of the plates to the temperature of the astrog;raph. This relation is presented graphically in Figure 2. The results obtained permit determining the scale of every plate according to the astrograph temperature during the time of observation and according to the fecal scale reading. It should be noted that, photography, as a rule, was done strictly by a focus with an acclxra.y to 0.1-0.2 iilm. This was achieved thanks to the use of data from a special astrograph investigation [ 6 ].

The investigation ruaulta show that there is a alight influence, of the denuity of the negative on the magnitude of the rr.(Uuu and it uhould be excluded 113). Thin excl.uoion we make airnu:I.- tanuouoly with the determination of the libratiori coefficient, introducing an additional term in the conditional equationu. Plate meajuremcnto were made on the KIM-3 meauuring machine by the Hayn method. Vector radii of limb points were measured from the technical origin of the coordinates (the mark close to the center of the Moon) through 60 on a positional circle. Thus, in each plate, measurements on 26-30 vector radii were made. The values of vector radii are free from the influence of differential refraction whereupon conditional equations of the following type were constructed: x coo Pi i Y sin Pi - Aro = RIO- ri (2) where x, y are coordinates of the mark, Pi is the positional angle of the limb point, J ro is the correction to the ephemeridal radius resulting from the observations, RIO is the ephemeridal radius burdened by the paral- lax, ri are the measured vector radii. The number of equations corresponds to the number of measured vector radii. From equations (2) the values x, y and 4 ro are found by the method of least squares. The average error in determining the Moon's radius by our plates is +0.''37. The solution of the system of equations (2) corresponds to the finding of the most likely circumferen-:e, which, by the best manner, coincides with the measured points of the Moon''s limb. Corrections for the nonuniformity of the limb to avoid systematic errors were not introduced. For investigating the libration effect, we selected and solved a 61 system with measurements on the western limb of the Moon and a h+l system with measurements on the Moon's eastern limb. In view of the fact that as a result of the solution of these systems of equations similar unknowns are obtained with weights of the same order and approximately identical accuracy, we assigned to them weight in relation to the quality of the negative (sharp- ness of the Moon's limb). For perfect negatives, a weight of 1.00 was used, for good - 0.75 for satisfactory - 0.50.

Convinced that our series of photo;raphic observations confirm the presence of the libration effect in thr. radius, we, by these same observations, chucked a model of the figure of the Moon suggested by A. A. Yakovkin. In the model mentioned, the presence in the region of the south pole of a plateau of variable thickness is assumed. In this connection of the limb of the :Lunar disc is described by a curve with two parameters: R = Ro + a cost P; a = 0 with 2700 L P < 900 (6) CPYRGHT Approved For Release 1999/09/08 : CIA-RDP82-00141 R000200360001-3 Approved For Release 1999/09/08 : CIA-RDP82-00141 R000200360001-3 ''Pliuu, thy. ri0L'tthu.rrl part ul' thu Muu-L' a :Cigw a IL; a humisplruru with a rad Lus Ito, and cuatuv cuiricidinf with thc cuntur of the maso.

We did not find such a direct verification in the literature. It Is known only from thu works of A. A. Yukovkin that this mudcl, according to indirect data, is probably not very far from the truth. On the basic of muaourcd vector radii of pointu of the limb systems of conditional equations of the following type were constructed: X coo Pi 4 Y sin Pi - A Ro - U cost Pi = R'0 - ri a 0 with 2700 Pi C 90o (7) where X and Y are coordinates of the work relative to the center of the most probable circumference which, in the best manner, coincides with the points of the limb of the northern part of the lunar disc, L R0 is the correction to the cphemcridal radius giving the radius of the: northern part of the disc, a is the thickness of the supplemental layer in the region of the south pole. From the solution of these systems X, Y, p R0 and a were obtained. The appearance of libration effects in the parameters 6 R0 and a, given in columns 3 and 4 of Table 3, occurred simultaneously with the appear- ance of libration effects in the locality of the center of the figure rela- tive to the center of the mass of the Moon. For this, the differences X - x and Y - y were constructed. These differences, constructed according to the results of solutions of the equation systems (2) and (7), are the coordinates of the center of the figure relative to the center of mass of the Moon which, according to the given model, coincides with the center of the northern hemisphere. For determining coefficients of libration effects systems of conditional equations of the type in (3), whose right side consisted of the values Lj R0, a, X-x, Y-y, were constructed. The solution of these equation systems by the method of least squares gave the following results: for the western limb U Ro 0".946 - 0".094 0 4 0".004 S' 0 4 0".054D ?172 ? 32 4 35 4 34 a 4 1".640 + 0".245 P1 o- 0".059 T 0- 0".023D; 4 281 4 53 4 58 1 56 - 13 - (8) (9) CPYRGHT Approved For Release 1999/09/08 : CIA-RDP82-00141 R000200360001-3 Approved For Release 1999/09/08 ?

In the L'uturu, It is plan ned to use the results of a lnypsoinutric study of thu Muon'u figure based on observations of the terminator. The basic conc.l.uoinni from the results of the work cited concerns the displacement of the center of the Moon'u figure relative to the center of its mass. Actually, the relations (:IA), (11), and (lh), (15) directly in- dicate how much the center of the Moon's figure is disp:laecd for one and the other coordinate due to the presence of the great relief. It can be considered fully proven that the existence of a constant correction of the latitude of the Moon, 0".50 on the average, is accounted for only in the presence of the: ai'orement;iunud .L c:l.ief . The difference ob- tained by Markowitz LJ.1EJ of longitude of the Moon, inferred for the western and eastern limb, aJ.so has its explanation in the presence of the great re- lief. These conclusions made previously by Yakovkin from indirect data are directly confirmed by our observations. The results obtained by us will make it possible in determining the coordinates of the Moon from limb measurements to allow to a certain extent for the relative position of the center of the figure; and the center of mass of the Moon. They will also serve as material. for further specifying the figure of the Moon and constructing an average chart of the limb zone.

U. MukuuLov, Corresponding, Member of the Academy of Sciences USSR and chief of' the Division of Astronomical Instrument Building at Pulkovo, describes some of the instruments and the work on their development at the Main Astronomi- cal Ubservutory, Academy of Sciences USSR, in an n rLiclc entitled "Pulkovo Today, for New Discoveries." Large telescopes and a variety of auxiliary apparatus are necessary for modern astronomical investigations and deeper penetrations into the secrets of the universe. The larger the telescope, says Maksutov, the greater the possi- bility for new discoveries. At present the Division of Astronomical Instrument Building at Pulkovo is working on the largest telescope in the world. Its mir- ror has a diameter of 6 meters. This is more than that of the famous Palomar telescope in the US, which has a diameter of 5 meters. For the production and investigation of the mirrors of large telescopes a compensation method- was developed by Maksutov. This method provides for a great economical effect, a reduction of costs and of production time. CPYRGHT In creating new telescopes, the workers of the division devote much atten- tion to the perfection of the most important detail, the main. mirror. "Since 1911," says Maksutov, "I worked over the meniscus systems. The meniscus is a lens which is located inthe converging cluster of rays not far from the focus. Because of this it was possible to reduce the measurements of the lens and the telescope." A number of such instruments are already in use at Pulkovo, Abastumani, and other observatories. Expeditionary telescopes (AZT-7) which are found in the expeditions of the Pulkovo observatory operating in the USSR for investi- gating the astroclimate with the aim of selecting the place for the installa- tion of the future great telescope are also equipped with meniscus lenses. These portable telescopes have small dimensions together with great power. A meniscus expeditionary telescope with a mirror diameter of '140 millimeters and an over-all length of only 25 centimeters was built recently by the shops of the Pulkovo observatory. Maksutov reveals that the Russkiye Samotsvety Plant has begun issuing meniscus school telescopes with his system and also long-distance telephoto meniscus systems for mirror cameras. At present the observatories are being used for the perfection of these systerfis. In addition to this, they are working on the development of a camera for artificial earth satellite observations which uses the meniscus system. The manufacture of a whole series of such cameras is planned. According to calculations these will have a 1:1.4x lens, an opening of 0.5 meter, and a mirror diameter of 1.25 meters.

Glaso is the most nuitable material for optical mirrors, but, 'since it is a poor con(Auc%.or or heat, changes in the shape of the mirror surface arise with heating. The larger the mirror and the temperature gradient, the greater the distortion. The quality of metallic mirrors in this respect is incomparably higher. Investigations on the use of automatic star followers for telescopes are being conducted by a group of workers at the observatory under N. N. Mikhel'son. This is achieved with the aid of electronic computers controlling the motion of the telescope.

Among the various groups conducting these investigations was the independ- ent expedition of the Geographic Faculty of Leningrad State University, composed of 18 men under Professor Drozdov. - 18 - Approved For Release 1999/09/08 : CIA-RDP82-00141 R000200360001-3 Approved For Release 1999/09/08 : CIA-RDP82-00141 R000200360001-3 The expedition undertook to orgunize meteorological observations at the tongue, in the central part of' the glacier, and in the i'irn 'zone, and Lo take part in microclimatic observations in the investigation of the tributaries of the glacier and in hydrological and geornorphological inves- tlgutions at the glacier's tongue and on the glacier itself. Drilling conducted at the ),88O-meter level (altitude) by Agashkin, a worker of the Institute of Geography, Academy of Sciences USSR, produced some very intereoting results. -At a depth of one meter the firn was moist and its temperature raised 'to 0 degrees. These temperatures showed little change down to 10 meters. Winds on the upper part of the glacier were found to be rather strong and constantly driving down the snowdrifts. The direction of the wind is almost entirely from the south, that is, down the glacier. The strongest winds are observed in the morning after sunrise but before the sunlight reaches the glacier. A system of valleys and depression which are favorable for the passage of winds from Central Asia cause the almost constant presence of unusual lenticular-type clouds over the Tanymas River valley. Another reason for westerly winds in this region is the enormous area of ice formation in the region of Fedchenko Glacier and the practically bare plateau of Eastern Pamir. The expedition compiled an album of high-mountain clouds according to data obtained in the Lastern Pamir and the upper part of the Fedchenko Glacier. Hydrological observations on the water discharge of the glacier were conducted. A comparison of a survey of 1933 with the 1957 survey made by the expedition made it possible to determine the glacier's recession for'thebe years. For this period the glacier receded 280-300 meters, during which the recession, judging from the moraine, was uniform. Materials obtained by the expedition are now being processed.

On 30 July, an extensive ice re:con.? nuissance flight was made with an 11-12 plane, piloted by V. M. Perov, commander of the aerial detachment of the expedition, with the participa- tion of Prof V. A. l3ugayev, chief of the aerial detachment, and the hydrologists M. Izvekov and V. Lebedev. The plane set its course for an ice island, or iceberg, located north of the Shackleton Shelf Ice, from where the plane went to the north up to the edge of the ice. The weather during the flight was not very favorable. Low cloud formations forced the plane down to the ice. The plane flew at an altitude of 200 meters, occasionally rising to 1,200 meters. Professor Bugayev conducted scientific observations of the air tem- perature and humidity and the wind speed and direction. Fields of brok3n ice with numerous icebergs stretched out below. Seals and penguins were seen on the floating ice floes. The ice fields soon came to an end, and, at a point with coordinates 60 37 S and 95 35 E, the water of the Indian Ocean was free of ice. From here the plane took its course toward Drygalski Island. and, after inspecting the island and exploring the east- ern part of the fast ice of Davis Sea, the plane returned to Mirnyy. On 1 August, the pilots made a flight over the western part of Davis Sea, during which the hydrologists obtained valuable information on the distribution of ice in that area. (Moscow) Sovetskiy Flot, 13 Aug 58) Fourth Antarctic Expedition in Preparation The Special Cormnittee for Antarctic Research recently passed a deci- sion to organize new scientific stations on the coast and in the interior of Antarctica; Preparations are now in progress for the Fourth Soviet Antarctic Expedition, At the same time, last-minute preparations are being lnade at the sta- tion Sovetskaya for a very important oversnow traverse, i.e., to the pole of relative inaccessibility. The distance from Sovetskaya to this point is 700 kilometers, and the route passes over mountain ridges rising more than 4,000 meters above sea level, across icy ravines and snow barriers. At the completion of this traverse, a new Soviet station, Polyus Nedostup- nosti (Pole of Inaccessibility), will be established. The organization of this station will complete the main part of the program of the Third Soviet Antarctic Expedition. At the same time, it will represent an impor- tant stage in the solution of problems which will face the fourth expedition.

In October the Lena, first ship of the fourth expedition, will Leave from the E:aliningrad port. This ship has made the voyage to the Antarctic several 'times. During previous trips, the Lena delivered its passengers and cargo to Mirnyy, the principal Soviet base. The route of the Lena on` its forthcoming voyage will be changed, and the ship will dock ut t1.(, coast of Queen Maud Land,! This will be the point of disembar- kation fur the first staff members of a new Soviet station, to be named after the famous Russian navigator, Mikhail Lazarev. After landing a group of geologists at the station Lazarev, the Lena will sail along the coast of Antarctica to conduct oceanological research. The Ob' will take a different route. It will' transport passengers and cargo to M:Lrnyy and will then sail to the western part of the con- tinent. Another Soviet scientific station will be opened there, on the coast of Bellingshausen Sea. A third ship, the Feliks Dzerzhinskiy, will take part in the Fourth Antarctic Expedition. This large, new Soviet ship, which is equipped for navigating in the ice, will carry members of the continental expedition, headed by A. G. Dralkin, Candidate of Geographical Sciences. Dralkin has worked for 20 years in northern latitudes and has participated twice in the work of the drift station Severnyy Polyus-#. The new continental expedition has a difficult task to perform. For the first time in the history of Antarctic exploration, almost 6,000 kilo- meters of ice plateau will have to be crossed. The Soviet explorers plan to complete this traverse in It months. The starting point of the expedi- tion will be the station Vostok. All the necessary equipment will be delivered to this point ahead of time. From Vostok, the members of the expedition will head toward the south geographic pole. From there, via the pole of relative inaccessibility, the party will head for the coast of Qu? n Maud Land, where they will meet with the members of the new Soviet station Lazarev. The continental expedition will consist of four truck-tractors. A Pingvin oversnow vehicle, which has easy maneuverability and has already proved itself in the Antarctic, will travel at the head of the column. This will be used as a "reconnaissance vehicle." Most of the equipment and the expedition members will be transported by three truck-tractors) specially built for this expedition. So far these caterpillar vehicles have no official name, but they have already been nicknamed "Bogatyri." They are not only scientific laboratories, but comfortable field living quarters, each one having a bedroom, workroom, and kitchen.

This station will be established at about the 10th degree of eastern longitude, between the Norwegian and Belgian antarctic bases. The USSR Antarctic Expedition will organize other new station: on the coast of Bellingshausen Sea and at the "pole of relative inaccessibility." The existing station Sovetskaya will remain at its present location. Aerial reconnuissunce has shown that the expeditionary party, which will travel to the pole of relative inaccessihtlity, will have to cross the highest regions of the continent. The station at this pole will be sit- uated 700 kilometers nearer to the south geographic pole than Sovetskaya. Instead of the originally planned transantarctic traverse, the new interior expedition is to be carried out in the form of a huge triangle, the sharp angle of which will be located at the south geographic pole. In connection with the wishes expressed by representatives of the Polish Academy of Sciences concerning their participation in antarctic explorations with Soviet polar scientists, the details of such cooperation with the Polish colleagues are now being discussed. As in previous years, the expeditions of the Soviet Union and of the US will have an exchange of scientists.

A Special Committee for Ant- arctic Research was formed to coordinate the Activities of scientists. This committee has worked out a plan for the further study of Antarctica. At the Moscow conference of the committee, it was recommended to the interested countries that new scientific stations be established in the coastal region of West Antarctica, between Ross Sea and Graham Land, on Wilkes Land, and Queen Maud Land, as well as a number of interior stations and island stations. In accordance with these suggestions, the plan of the Fourth Soviet Antarctic Expedition was prepared, which is to be carried out by the Arc- tic and Antarctic Institute in cooperation with other scientific institu- tions of the USSR. A. G.'Dtalkin, Candidate of Geographical Sciences, a well-known polar explorer, will. be the chief of the new expedition. Soviet scientists intend to reach a final solution to the question of whether Antarctica is actually a continent or an archipelago of islands buried under the cover of ice. For this purpose, measurements of the ice cover between the station Vostok and the south geographic pole are to be- gin during 1958. In October-November 1958, the station Sovetskaya is to be moved to the location of the pole of relative inaccessibility, i.e., about 700 kilo- meters to the southwest. Two new Soviet scientific stations are to be established in places recommended by the Special Committee for Antarctic -Research: one on Queen Maud Land in East Antarctica, and the other on the coast of Bellingshausen Sea in East Antarctica. These new stations will be named after the Russian navigators, Bellingshausen and Lazarev. All other Soviet antarctic continental stations, except Pionerskaya, which will be closed in January, will continue to operate.
