THE PROBLEM

To estimate Soviet capabilities and probable accomplishments in space over theoears.

SUMMARY ANO CONCLUSIONS

space program hasigh priority amongobjectives. Tho number of space launches attemptedpast two yean was nearly equal to the total of theNevertheless. Soviet achievements were less spectacularFor the most part, the Soviets exploited existingcarry out unmanned space exploration and intensive satelliteand to expand space applications. There have beenflights since

nature of the spectacular but believe that the event will be confined to 'iii'Si space.

of the Soviets space program hive risen sharply overfew years, but now appear to be leveling off. The programtun oe toignificant share of resouroes of the seme typefor strategic military pirigiami and for econumicthe present Soviet leaders may try Io effect economies insectors, we coosider it unlikely that they can effect anyin the overall nature of the program for tho next fivefor the longer termtoearsdoubt thatleaders hive yet come to firm decisions es to the scopeof their space pro gram, certainly we have no basis forof Soviet space activities during this period.

view of cornpettng claims on their resources, we believeSoviets wiD riot be able to undertake simultaneously all thetheir techiucal nubilities. Further, we do not believe thatwill seek toarge space station and to achievelunar landing concurrently. The dates estimated forare based on technical feasibility; we cannot estimate theIn which they may be attempted.

Lunar Landing. Two yean ago, we estimatedSoviet manned lunar landing program wu probably notbe competitive with the ApoDo program as then pjofected,atime period. We believettTJ theIs the possibility, however, that depending upon theirnstable, the Soviets may feel that there is some prospectgetting to the moon first, and they may press their programof being able to do so. Considering the Soviet technicaland the various techniques that might be employed, wetbe ear lie it the Soviets couldanned lunarbee believe that the most likely dateinime period.

C. Manned Ctrcwnlunar Flight. The Soviets will probablya manned circumlunax flight during the nest few years. They probably coosider this venture one of the few vrithin their capabilities that could offset some of the propaganda valueuccessful US lunar landing. We consider it unlikely that the Soviets would attempt

this mission before the first halfi though It is conceivable that they would accept the high risks involved in making the attempt as an anniversary spei-taL-ular in

Space Stations. We believe that the establishmentmanned space station isovietpaceounds weight and capable ofrew ofmore could probably be orbited by then the first half ofusing tbe very large launch vehicle, which wo estimate isat Tyuratam, the Soviets couldpaceounds by aboutt the earliest,believe sometime inime period to be more likely.

Systems. The expansion of tbe Soviet satelliteproject over the last two years shows that projects ofstrategic value can and will be funded. The Soviets willcontmue to support this program at about the present levelit with improved collection and data-handling systemsnext few years. They will probably give in creased emphasiswhich have both civil and military supporteteorological, and navigation satelbtes.

J. During the past year, the Soviets have conducted flight tests which could leadtrategic space weapon system. We estimateractional orbit bombardment system could be deployed in small numbers by7 ore cannot at this time estimate the likelihood that the Soviets will choose to deployystem. On the one hand, it would complicate the US defense problem; on the other, it would be more complex, more costly, and less accurate than ICBMs. Ifystem Is deployed, the Soviets would probably regard itupplement to existing strategic attack forces and would deploy it In relatively small numbers. In view of Soviet agreement to the treaty on peaceful uses of space as well as theultiple orbit bombardment system, we do not believe that the Soviets will deploy and maintain weapons in space during the period of this estimate.

the past two years the Soviet program of lunar exploration hason two objectives: soft lunar landing and orluting the moon. Both

objectrves hive Included photographing the moon'i surface.

IL Until recently tbe Soviets had used every opportunrty available to launch probes toward Verrui and Mars arntw their Interplanetary probe programhey did not. however, take advantage of the "window" to Mars which opened7 aod dosed lo February. Failure to capitalize on thus opportunity may Indicate that tbe unprofitable planetarybeam curtailed ba an attempt to reduce expenditures for space.

II. SCIENTIFIC AND TECHNICAL FACTORS AFFECTING FUTURE PROSPECTS

enerai Soviet capabilities to the basic and applied sciences will probably be adequate throughout the period of this estimate to support an ambitious space program. Any difficulties encountered are more likely to arise from trjeh-nological than from sclrmtlflc limitations. Space payloads designed by the Soviets bave historically been much heavier than their US counterparts, in part, because of their early decMoo to develop boosters of very large thrust and. In part, because of their tendency to use cumbersome, but proven campements and subsystems rather than develop new, more advanced hardware specifically for space.

h* weight [serially imposed by tba Soviet pnctkMg heavier, and simpler equipment in ipace payloads ii not critical for near-earth operation!.believe that currant Soviet technology could be rot coded with cornparative eaaa to conduct further operation* of thii typa ln more amhUknu programs, ruchanned tuner landing, the aaving of weight ejsumee greater Importance. Advances In rrdruaturitatioo, packaging, and other weight saving techniques as wall as more powerful propellent* would be needed to make more complicated millions practicable Etevcloprornt of such technology Is ahncet certainly under-way at the present time.

Wo believe that initial unmanned brings of theonventional third stage will occur tn the first halfanned Sights using this system could begin some ssx morrthjear later, depending on the rapidity and success of the unmanned testing.

We have previously estimatedew oery large launch system Is under development. There is evidence that the Soviets areery large launch facility at Tyuratam which is probably of the aame magnitude as the US Apollo launch camples at Merrill Island. We estimate that this fadllty wiQ be ready for mftial launch Crperatsdo* to the first half8 at the earliest. We have no direct evidence of thef the oew very huge booster but consader It likely that ft willirst-stage thrust In0 pound range.

Tbe useigh energy propellent in thejection stage for either of these coqUxMtioos would aDow them to be reedy for manned flight0 or shortly thereafter.

During the flight of, aplsae adhrstnseots were made In the orbK. This sod other data received on the flight of these two vehicles lead us to believe the Soviets areew macecrafL

We have fnniffidoit data to evaluate hilly the charact eristics of this new spacecraft. Tire weight theystem can place into near-earth orbit is limited to0 pounds. We think theehicle weighedounds. These Stings probably were for the purpose of checking newly developed capsule subsystems as well as testing an entirely new spacecraft.

A new marreuvernbl* spacecraft, about the weight of the Voskhod but with more osable volume, wouldery valuable adjunct to some of the space ventures, suchanned circumlunar flight. In which the Soviets have expressed interest.ehicle could be designed lor rescue, ferrying andpurposes and thus could be useful toong-lived cebrtmgIt could also be adapted to an unmanned reconnaissance mission. Ifere, in fact, the first testew spacecraft, an Initial manned flight could occur bye believe the Soviets will develop still larger and more efficient manned space vehicles which will allow more sophisticated and venturesome missions to be performed.

Command and Control for Neat-Earth OfhU. The Soviet capability to undertake complex earth orbital operations is limited by certain majorin the USSR's command and control network. Although we believe tbe internal command and control network generally will be adequate to support most single missions, tha lackorldwide tracking and communicationsmay handicap the Soviets tn the performance of. some orbital operations and willevere handicap if the Soviets attempt to control several operational systems, each consisting of several orbiting vehicles. Major Improvement to Soviet tracking capability would result from additional tracking stations almost any place outside the USSR. Soviet interest in acquiring tracking stations abroad has been high. Cuba, where th* Soviets have installed an optical tracking station and are going toolniya receiver station, may be tbe site of the first Soviet land-based tracking station outside the territory of the USSR. Soviet efforts toracking station in Australia have been frustrated. Current Soviet activities in th* UAR and Somalia may foreshadow attempt* to establish tracking stations in one of those countries.

ommand and Control for Diep Space. The deep-space tracking facilities located In the Crimea and currently used In unmanned lunar and planetary flights limit tracking and communications to interrupted schedules. The actual time available for tracking and communications for lunar probes depend* upon the hinar declination and varies fromoay. We believe that the ability to track and communicate with manned lunar flights4 hour per day basil is needed to help insure the safety of such missions. The Soviets could, however, undertake manned bin or flights even with their limited tracking and communication capability by accepting the calculated risk of not being able to communicate with the spacecraft for certain periods of tun* If the Soviets constructed facilities In their Far East areas, they could Increase significantly the time available for contact with theb lunar missions There is no evidence that

any VcoaTperarJe too US* Crimea are being installed anew he ie. however, and we relieve their construction would require at least two years

The Soviets could alio extend the tarse available lor corrixrrcaucannj with their lunar mission by using appropriately equipped ship* as relay centers between the spacecraft and tha control center. To be effective,ystem woulda high capacity communications link between the ship and (he control center. Wrthout this high capacity link, eoerrmunlcetlons would be united to relay nf verbal icjuTjcnonj and lystem status rainrnaries and would oot permit positive rtuaaibn control. We have ao evidence that the Soviets have rrartaOed th* necessary aournarreM on any of uSerf surface shape a* yet butystem using such ship borne relay hnk* ia wall within their cnpabtitty. The Soviets could conceivably use coramurucaiione satellites as relay linkssurface riatious for deep space nights.

flandnoour ond Docking. Critical to many advanced type* of manned space missions is the reoutremerrt lo develop techniques for remdezvous and docking of vehicle* In space. New Soviet spacecraft, unlike tbe Voatok and Voskhod. wiC probably be designed for reodervous and docking and willthe necessary ecjurpenent for rrurneuverablhry. engine restart, and hook-up Soviet technology is ruffldenOy advanced to make available tbe various seniors required for such, radar and transponders. Ifere the initial teatsew spacecraft designed for reodazvoua andthe Soviets could conduct initial manned mluions of these types using currently available launch ryrtenu within the neat few months.

useoesry. Tba point of reentry into tbe earth's atmosphere of lunar return trafactorJae would beouthorth ktJtirde on thaurface, dependmg upon th* declmenon of tha moon at the time of the tight. The Soviet land mas* He* well north of this band Thus, any spacecraft which did not axorporate some mean* (or altertng its reentry trajectory could not be recovered within the USSR. Since we believe having an co-board propulsion system for altering reentry ttarectories would be Impractical, tbe Soviets need topacecraft having some aerodynamic bit thai ait eristics or, akorna-lively, toater recovery capability. There are no arm indication* that the Soviets have conducted aerodynamic reentry teat* or that they area water recovery capability but testa of either could begin at any tunc We believe that the tfert* required toecovery technique would notinting factor In the Soviet manned lunar program.

aeniry. Some Soviet scientists have Indicated that reentry at lunar return velocities is one of the major problems confronting them in their lunar program. The angle of reentry Into tho earth's atsrscepherc must be kept wflhtn very narrow bkrets. If Use angle at too steep, accelerations would be too greatanned spacecraft to wit bet aad On the other band, if the reeatry angle I* too shallow the spacecraft would "ikjp" ofi th* earth'* atmosphere back tnto space.

During theears the Soviets have been pursuingirected toward the devearsprnerat of fuel cells. Performance leering of fuel ceBs using the hydjogia-oaygen reaction prtrvctple Is probably underway and inoviet electrocbemiit claimed that they have successfully developed fuel cells having one Wlowstt output We estimate the Soviets oould have fuel cells suitable for short space missions now.

Bkmtdical. The Soviets probably now have rufBdent biomedical data to plan withanned flighteeks, this would be adequate totanned crrrsuralraraar or lunar lending rrusitoa Al present, however, the Soviets appear to be concerned with the eflecta oo human beings of oon-siderabry longer duration flightsboutays orhere are few indications of how tbey wiD solve the baornealical problems associated with flights of that chjabon. but wa believe thatolution, should be ready fn time for long-diiration projects tn the next few years.

The Soviets have srumerrjssa faalrtiea for simulating various aspects of space envtronmeot including cerstjifugestresses, low pressure and lowchambers, suspension devices for snrrulsting reduced gravity, and various devices and equipments for experimentation wtth moo and animals In closed environments. These facilities and activities are probably adequate to support any of the various manned space versturea they may attempt.

ssde from the aoeratrSe and tctssrucsl cceisldeseiicn* which we havethereariety of other factors which wiD influence the scope and pace of future Soviet space endeavors. These include such things aa the effect of past decisions, lhe views of tbe present Soviet leader? on the benefits to be derived from their space program, costs, the need for regaining lust prestige, and Soviet views on the US program.

We are unable to identify organisations snd individuals directing and executing the Soviet apace program. Broad policy directives on all apace maters are probably Issued by tbe Fohtburo of the Communist Party of the Soviet Union. We behove that these chrectrves are trrmlrmvrrrtedu'gh-kvel commission corrrpoted of both government and patty ofBciab- The Ministry of Ceneral Machine Building, supported by the industrial mmistries such as defense,radio, and electronics, rxobohty as responsible for the development and production of space hardware. The Academy of Sciences provides scientific espertlse to Ihe entire space efiort, cootrols scientific programs, and acting principally through the Commission for the Expke-atlon and UtilluliOD of Spaceponsors representatives at mternatsonal meetings.

The Soviets almost certesnly have already decided the nature of their space program for the nest five years and have probably established an appros> mate timetable for the vartoos activHkea related to that program Whale it tt pnssihle to stretchrogramonger period of rime than originally plannedeven to speedrogram eomewhat to meet new deadlines, it is

extremely difficult to re-tailorprogram In Its late stage* io meet an entirely different objective than was initially established. While the present Soviet leaders may try to effect economies in certaih sectors, we consider it unlikely that they can. at this late date, effect any basso changes In the overall nature of the program for tbe next five years.

Based hugely oo analogy with coats of tha US space program, we estimate that expenditures in the Soviet space program have been rising at an average annual rate roughly equivalent to USillion3 when aboutillion were expended,8 when aboutillion were expended. Much of this increase is accounted for by the major launch facilities at Tyuratamthose which we estimate are being developed for the eery large launch system. We believe the latter program Is sufficiently advanced to permit the overall cost of the Soviet space program to level off shortly and bold at about5 billion per year for the next few years. These costs include our esti-mates of both th* military and nonmllrlary porticos of th* Soviet space program.

Th* recently signed Outer Space Treaty is not likely toignificant effect on the military or pop military aspects of the Suviat space program. Tbe treaty prohjbits the estsbhsbroent of military Installations, the testing of any type* of weapons, and tbe staging of military maneuvers on celestial bodies. It also ban* placing nuclear weapons In earth orbit and on celestial bodies, but ft doe* not prohibit the development or testing of delivery vehicles for an orbital or fractional orbit weapon system. Further testing of theystem would not be contrary to th* treaty as long as such tests did not Involveuclear weapon Irs orbit Deployment of an operational system on the ground is not prohibited.

he treaty permits the use of military petrsoonel and eqiripmerit for the peaceful exploration ofexample,anned space station or forducting scientific research oo the moon. While there is no specific mention in the treaty of satellite reconnaissance, the Soviets made no effort to revive 'heir old charges that such activity Is illegal and they seemed to accept it a* legitimate.

The extent to which the treaty wfH help the USSR ropplement its own space tracking capabilities Is uncertain. According to tbe treaty, parties to the treaty 'shall consider* requests of other signatories to be afforded anto observe the flight of the requesting state's space objects; tbe nature of this opportunity, as well as the conditions under which It would be afforded, would be determined by agreement between the states concerned. However, other sigrratory nations are not obliged to grant any Soviet request for observing its space objects when they are out of view from Soviet territory.

Tho Soviets probably feel that during the next few years they must take steps to regain some of the prestige they lost to th* highly successful US Gemini program. Furthermore,7 two important anniversaries wiH be ob-

TOPJKJW-

served uj Ihe USSK.h anniversary of thendhof the October Revolution. The Soviets probably have planned some form of space spectacular to celebrate one or both of these dates. Somewhat later they will be confronted with the necessity to at least partially blunt tbe rrtternational impact of the US Apollo program. For thee* reasons andhe capability of the space hsddware which they are now developing, we beheve that tbe next five years willeriod In which the Soviets will attempt space ventures far more complicated and spectacular than heretofore undertaken.

IV. OUTLOOK FOR THE NEAR. General

n considering developments In the Soviet space program over the next five years, we can estimate feasible extension of all current projects but rt is difficult lo determine which specific missions will be flown. We do not believe the Soviets have at hand all of the necessary technical and economic resource* for undertaking all projectse therefore believe that some possible project* will not be attempted, others will be slowly paced, andresources will be committed toew. The expansion of theproject over tbe past two years shows that project* of demonstrable strategic value can and will be funded. While it is dear that useful missions can still be accomplished with existing hardware,qually clear Ihat more spectacular and sophisticated missions will have to await the new hardware now under development.

he Soviets fn their many official and unofficial statements about their space program, have given no indication of what the order of priority is to be. Indeed, much of what Is saidonflicting or ambiguous. In arriving at likely dates for specific missions, we haveigh but not complete level of successharing of priorities amoog several categories of projects. In general, tho likely date tor any given mission wouldear or so later than that winch we consider to be the earliest practicable date. We note that delays and failures have occurred and have socnctUr.ca plagued the Soviets for longuch difficulties can recur at anyupon theof hardware based on new and more complexcould delay achievementpecific missionear or two.

be Soviet manned lunar landing program and th* huge manned space station program are large-scale undertakings, both of which require tho use of tbe oery large booster and associated launch facilities which we estimate are being developed at Tyuratam. The dates we believe these venture* can be carried out are based on technical feasibility and do not fake Into account the order In which they may be attempted. We do not believe they could be undertaken corrcisrreotly. It must be understood therefore, thai the one which bt given priority may be carried outhe time indicated and that the other will he deferredear or so.

B. Manned Lunar Landing

In5 we estimated that the Soviet maimed lunar landingwas probably not Intended to be competitive wtth tho Apollo program as then projected. Lev, aimed atime period. We believerobably still the cue There is the possibility, however, that depending upon the present Soviet view of the Apollo timetable, they may feel that there Ii noma prospect of their getting to the moon first and they may press their program in hopes of being able to do so

Several fact on militate against their being able to compete with the ApoDoriginally planned. We believe that the required launch system will not be ready for test until aboutaunch vehicle is available, we would espect toeries of tests for man-rating the system est ending over atearunar landing would be Attempted Io the meantime, the Soviets will need to checkew spacecraft, to teatst lunar return velocities, and perhaps toater recovery capability. Depending upon the technique relected, they may also need to test rendervous and docking techniques and equipment.

5B. Some Soviet scientists have criticized the Apollo technique and stated that their lunar flight will go directly from earth to tbe moon's surface and return without any orbital rendezvous required. We estimate that any lunar landing mission whichingle vehicle using conventional propellents wouldooster developing considerably greater thrust than any weare being developed. The Soviets have alsoechnique involving the placing oi components and fuol on the moon by two or mote very largethen having cosmonauts assemble these components oo the moonehicle and fuel it for direct return to earth. This technique is risky since very accurate guidance is required to place the manned vehicle sufficiently close to the landing site of earlier flights and there is no provision for an abort of the manned flight.

Other Techniques could involve rendeavour and docking of two or more very large vehicles in earth orbit for assembly and fueling the hrnar vehicle, before proceeding to the ntoon. The Soviets could alao carry out two launches to the moon, one for landing an the moon and return to Kiner orbit, and the other for lunar orbit and return to earth. Either of these otisssoos could be attempted within the cspabQltset we believe the Soviets will have when the new eery large lauoch system is available.

If. however, the Soviets were to develop high energy propel lants for use In upper stages of the new eery large launch vehicle they could use anyide variety of mission profiles toan on the moon and return him to earth. We have estimated earlier that man-rated upper stages using high energy propcDanU could be available0 or shortly thereafter.

All things considered, we estimate that the earliest the Soviets couldanned lunar landing, would bee believe that the roost likely date isInime period

V. THE LONG T'RM OOTLOOK A. foctors Affecting

bar* httl* evidence oraacernjng long-term Soviet objectives itcan estimate th* Ulely scope of the Soviet spacenlyery tentative basis. Some cosmonauts, scientists,other Soviet space enthusiasts have often referred to possible futureas toterpknetary ezpicaaodo, but the political leadership during tbe pastor so ba* made little public reference to rpace acflvrtiaa, and has avoided

any opm reference toprograms boy' Tho leadership has probably not yet decided which particular venture* to empbaxiso ben/cod the manned lunar landing era, and almcet certainly her been unible to gauge with any degree of precision the ernounl of reeources Hfceiy to be available for apace program* in the neat decade.

The question of resource aBocnHonentral one in Soviet polities. Competition for resources hat intensified since the, when the marked slowdown in Soviet economic growth began, and political inflghting. in pert based on this competition, has become characteristic of fare within the leadership. The post-Khriuhcfsev collective leadership has not Indicated any substar.tial ability to resoNe problems associated wtth the establishment of economic priorities; ft has as yet been unable to agree on the final version of the current Five-Year-Plan, which began moreear ago. In tbe meantime, competingand space, growth andall, in effect, been assured high priorities.

One of the principal causes of economic difficulties in tbe USSR during3 has been the preemption of highly skilled human resources and top-grade material reeources by rapidly growing programs to advanced weapons and space- Among other things, these pogrom* have impfnged on the quality and effectiveness of investment elsewhere in the economy, and the present collective if surely aware of tins. Aside from eScats to achieve DiarginaJ economies,the leadership has not sought to attack the problem by reducing or even leveling off erpendltures lo these areas, and we estimate that it at unlikely to do so over the next four or five years. If important programs must be cut, avilian claimants are the most likely to suffer, as in the recent past.

OS. Whether the Soviet leaders will be willing to approach the problemew way Inul of course, depend on many factors: tbe state of tbe economy, the international climate, the composition and nature of the leadership, the mterptay of domestic poUtical and economic pressures, the progress of specific military and space programs, tbe progress and scope of comparable US programs, and tbe leadership's calculations as to the costs of the program versus its probable returns, scientific, military, and political Tha latter factor, the political, hi likely to he of particular rnrportsuxe. The propaganda and prychologicel benefits of the program, both at borne and abroad, have always been of prime interest to the Soviet regime; tbe USSR's pJorseertagIn space added greatly to its International prestige and probably helped to justify the regime to Its own people. It may be, however, that such benefits wul drmiruah with time and familiarity, and that Scrviet prestige is less bsrery in the future to increase agnificaatly on the basis of individual exploits, such as Sputnik.

ossibility of Soviet Cooperation in Space Matters

Until recently, the Soviet- hud rtsunchry refused to offer any mdkatkni that tbey were wflltng to cooperate in soy field of sptce activity.2 the Soviets agreed to exchange satellite -collected weather data with the US, and in6 passed the first of their data to the US. This step plus the cooperative Soviet attitude evidenced during the recent discusaions on the UN treatypeaceful uses of space and the sg-reernent with France on relay of TV and other cooperative space projects lead us to beheve that the Soviets will become more willing to exchange various scientific and technical data with the US and ether nations as the various programs progress. Tbey may, for example, be willing to exchange such data on radiation belts, solar effects, gravity anomalies, additional aod more detailed meteorology.

Apart from technical difficulties, there are three factors which would tend to limit tbe extent of Soviet cooperation Id space. First, the prestige of being tbe first nation to accomplish various space missions continues to he Important to the USSR. Second, the prospective gain in cooperating beyond the exchange of scientific and technical data would have to be convincing to the Soviets as long as major International political Issues remain unresolved. Third, the close association of military and civilian space programs in tbe USSR would restrict tbe areas of cooperation which the Soviets would be willing to consider. We believe, however, that if the advantages to be gained are persuasive, the Soviets may agree to some ventures in which compatible equipments could be launched by the USSR and another nation and link together to perform functions of mutualommunications systemarge portion of the globeorldwide meteorological system. We consider it unlikely, however, that within the period of this estfmato the Soviets will be willing to coerperate to the extent of exchanging space hardware.

We have considered the possibility that at some time beyond tbe lunar exploration eta the costs and technical complexity of more extensive planetary exploration may be so great that ooe nation would not consider ft feasible or practical to undertake tt. We believe it less likely that the Soviets would be wining to Join the USilateral venture than to participaterogram sponsoredroup cfne under the aegis of the UN.

C. Possible Undertakings

ecause we are unable to estimate Soviet intentions in space over tlie long term, our consideration of possible space activities must real heavily on our estimates of likely Soviet capabilities tn the field. Moreover, even on this bards, we must make the assumption that the various projects tbe Sovietsin the near term wiD for the most part be successful and that long-term ventures will be sble to proceed from earlier achievements.

oviet writings and oratory haveroad spectrum of potential undertakings in apace but have railed, probably deliberately, to highlight any particular one or ones as those likely to be pursued by the USSR. However.

curtain venturer are mentioned more often than others and thb repetition may provide the clue to future Sovieteview of Soviet wrfftogi, speeches, and mtervfews over Ihe part two year* lhowi that the following possi-UUtiej are th* meat often addraesed:

In these discussions, tbe Sovieta do not describe tbe means of puttingtation In place, but restrict the discourse to desirabilityase of thb type and the scientific advantages to be gained The constructionanned lunar base of the sire and nature Implied in the Soviet discussitms would be extremely complex and costly, and would require tha Soviets to develop equipment and techniques far morethan we IseUeve that they wiD be able to achieve within the nextears.

A tune table for the Soviet manned planetary exploration program has probably not been established Soviet developmentapability tolaunch manned vehicles from an orbital apace station launch platform could eventually lead to manned fly-bvs of Mm, Venus, or other planets. In thb correction, the Soviet* are actively engaged In the investigation of advanced electrical propulsionhich would bo efficient means of transportingpayloads over interplanetary distances. The Soviets claim to have testedevice for attitude control of thepacecraft, which they launched towardowever, the Soviet lackuitable nuclear power source for an electrical propulsion system would precludeery large payloadlanet before tbet the earliest Thestlrnatad toeriod of decreased solar activity andavorable period for such Bights. We believe, however, thatnlikely that the Soviets will have advanced sufficiently far in their programs to attempt any such flights by that time, chiefly because of th* problems inherent io the developmentife support system capable of supporting manned flights of the several years6 for interplanetary travel.
