SUMMARY AND CONCLUSIONS

Soviet* un?esearch nndfacility tn sirnuluic conditions found in onlcr space and nil tlie limur surfucr. They have contracted with mi Austrian firmiwl ofillion lor constructionanned liypnhnric chamlirr. associated equipment,uilding to home the facility. Thr primary purpose of ihis facility, known asutya.o nmdiiet physiological trsilnfi on human suh|rctsimulated spucc environment. Ounplrtlnn of the fadllly Is scheduled furest program Is expected to Iwfiin curlytlar simulatorreadmill used in eomliiiiulionock und tackle urmngrinciil to slmulalr rrdiicrd gravitational forre will penvldr Ihc in*crssnry ri.ru ns ofosmonaut during both oditlnl nnd simulated lunar surface esta vehicular activity.

The tr-ling will lir enndueted by medical nrrunwl andI will require al least two phy.slcians. tmt physinlogls.s. and un elect miili* riigiiiref phis numerous support personnel to operate the fueillty. ll appears thai the IcnI faHllty will Im* operatedermanent Irakis nnd ihat ihe Soviets are ansinus to have Itoperational soon.

The hypnharir clmmltrr almost rcrlniiily will he used lo test mace suits, InvMtlgiilr human phy*iolor> y. and measure energy rxpcndllorr* under bothand lunar cundlllnm. Theric facilityood indicator of Soviet Intentions for manned lunar niiwlom nnd the Soviet cnntmctiiig effort implies some urgency. Missionowever, will depend ml well on Snvlrt progress in other phases of activity, such as development of Imostrr. and spacecraft.
