MOSCOW , Friday, March 19Air Force officer ,

who yesterday became the firstman to leave an orbiting spacecraft and float in space, wasstill circling the earth earlytoday in the capsule with afellow astronaut.

Lieut. Aleksei A. Leonov

30 years old , left the two-manVoskhod 2 as it passed over theSoviet Union while completingits first orbit and beginning its

second. He stayed outside thecabin for 10 minutes, accordingto Tass, official Soviet press

agency.

The spaceship , piloted by Col.Pavel I. Belyayev waslaunched at 10 A.M.

time yesterday , 2 A.M. Easternstandard time . The launchingsite, not announced at first , waslater said to be the cosmodrome

Baekonur in Kazakhstan . All

previous Soviet manned spaceshots have originated there.

[ Vasily Seleznev , a leadingSoviet space official said onMoscow television Thursday

that the target before usis the moon , and we

hope to reach it in no distant

future " The Associated Press

reported .

RumoredThere was widespread specu

lation that a second spaceshipmight be launched sometime today in an attempt to effect forthe first time a link -up of twocrafts in space .

As Colonel Leonov traveled

through space tethered to

his ship at a speed of nearlyfive miles a second , he was

shielded by a specially equippedspace suit . This protected himfrom the intense heat of the

sun

Specialists said that even the

slightest penetration of his suit

by the sun's rays would havecaused instant death

If the five - yard rope lifelinethat connected him with theship had broken , he could havebeen lost, orbiting the earth asa human satellite. His bodywould have burned up on reentry after a week or perhapsmonths of orbiting.

No Steering Devices

His space suit was notequipped with any devices bywhich he could have steered hisway back to the spacecraft.

Voskhod 2 was orbiting every90.9 minutes. The apogee, orhighest point , of its orbit was

approximately 309 miles , higherthan any previous manned spaceflight . Its perigee , or low point ,was given as approximately 108miles.

American space experts saidthey thought the launching wasperformed by the same vehicleused in earlier Soviet spaceflights , developing a thrust ofabout 900,000 pounds . The fact

tronauts close before openingthe outside hatch .

On a televised discussion of

technical features of the flight

later in the evening Sovietspecialist said the second orbit

had been chosen for Colonelexperiment because at

that time of the day radiationand sun heat were smallest and

there were no sun flares

Laymen observers here hadbeen wondering why such an

early stage of the flighthadbeen chosen for theexperiment rather than a later orbitthat presumably would havemade it possible to bring himback more quickly for medicalexamination on the ground .

The space used by Colonel Leonov when he steppedout of Voskhod 2 yesterday

seems to have been designed forshort-duration support outside the craft

For the ten minutes the astronaut was in space environment, he was tethered to thecraft by a lifeline that suppliedthe space suit with oxygen andwith air for ventilation andcarried communication linesmuch in the manner a deepsea diver is connected with thesurface.

More advanced space suitsdesigned for prolonged work inspace , in assembling of spaceplatforms or for landing on themoon will probably carry alife -support pack on the back .

The packs would also beequipped with low - thrust rocket engines to enable the astronaut to maneuver in space andreturn to his space craft underhis own power.

A commentator for Tass described Colonel Leonov's spacesuit as a " miniature hermeticcabin " consisting of a metalhelmet with transparent visor ,a multi layered pressure suit

and specially designedfootwear

The suit was said to beequipped with its own powersupply for communications and

Millions of Soviet and European television viewers watchedthe latest Soviet space exploit .

They saw Colonel Leonov

emerge from a hatch in the roof

of the capsule . He stood in thehatch for a while , moving his

left hand as signalingThen he pulled up his legs

and holding onto handrali,

pushed them out horizontally,like an athlete on parallel bars.

Then he pushed himself awayfrom the ship but remained con

to it by the lifeline.He floated at first witn

outstretched legs.he did a slow -motion somersault in the wake of the sh.p.turned around like a man

Colonel Leonov was feelingwell both during his period outside the cabin and after he reentered the spacecraft , an announcement said

At 5:30 , Moscowtine reported that thespaceship had completed its 13thorbit. Shortly before, an officialannouncement had said thatsystems aboard were functioning normally.

Biological research conductedduring the flight, the announcement said, yielded informationabout physiological reactions ofman during free movement inspace and about the nature ofthe motions in these condition

During the night Tass alsoreported the astronautsslept in turns , rested and break

in contact with the earth

by short wave radio only , sinceit did not pass over the SovietUnion during these orbits.

Earlier, while television wasshowing Colonel Leonov floating in space , an announcersaid :

" You see , one can work inspace."

Shown on Live TelecastThe pictures of Colonel Leon

the cabin were onvideotape. Later during theseventh orbit of the space ship .there was a live telecast showing the two astronautsstrapped inside their cabin with

sunlight streaming in throughthe

The dramatic Soviet achievement was believed to havetridened the advance of theviet space program over theAmerican one .

Western diplomats here believe that the Soviet flighthad been timed to precedethe Gemini shot the firstmulti-manned flight Amer

, which scheduled fornext week .

Soviet announcers and commentators were jubilant overthe new Soviet victory .

Soviet have often

shown that they feel fiercelycompetitive about the spacerace with the United States.

Practically all the membersof the Soviet Government andparty leadership gathered in theSverdlov Hall of the GreatKremlin Palace to follow theflight and watch Colonel Leonov

float in space.

Greeted by Brezhnev

When Voskhod Sunrisepassed over the Soviet Union

again on a later orbitBrezhnev , the First Party Sec

retary picked up a white phone

on a table and spoke to theastronauts .

Reading and impassively from a prepared script.he congratulated them in thename of the leadership . Thescene was televised .

Premier Aleksei N.was sitting next to Mr. Brezh

and the other leaders, including President Anastas I.Mikovan were their side.

Television viewers could hearthe muffled voice of one astronaut as he answered Mr. Brezh

greeting. Then the leadersclapped andMr.Brezhnev said :Weapplaudyou, we wait

for you in Moscow."The formal scene had nothingin common with the relaxed ex

travaganza staged on such occasions by Nikita Khrushchev, the former Pemier.

When the Soviet Union's lastspaceship Voskhod I. was

launched last Oct. , Mr.Khrushchev spoke to the crewin gay exuberant and im

provised give- and take at the

end of their first orbit . Butwhen they returned , he was no

longer around to welcome themback .

Early in the flight yesterdayColonel Leonov sent a message

assuring the " Leninist Central

Pressure

According to Tass, it is impossible to simulate atmosphericpressure within the suit becauseit would then inflate like a football and man would turn into astatue unable to bend legs andarms.

Soviet research said tohave shown that the air pressureinside the suit should be at leastfour tenths of an atmospherewhich is the pressure of air atsea level. Even then , the commentator said , the space suitinflates and bellows - like devicesare required at the joints to enable the astronaut to moveabout and work

To prevent the spacenian fromsuffering from the so - calledbends disease at low pressure

physiologists hit upon the ideaof eliminating nitrogen from hisbody before he enters the spaceenvironment . This is achieved byprolonged respiration of oxygenthat " literally washes nitrogenout of the body tissues , permitting the pressure to be safelyreduced , said .

The presence of nitrogen inthe blood stream causes bubblesto form in the blood when airpressure is too rapidly decompressed . This condition , knownas the bends , is often deadlyDeep - sea divers, among other

kinds of workers face thisdanger.

The space suit was said to beequipped withanair conditioning system through which ven

tilating air at room temperaturewas pumped to carry away excess heat and moisture exudedby perspiration .

protect the spacemanfrom the heat of the sun's rays

and from the cold in the shadowof the earth or of the ship,the space suit is with athermal insulating layer and iscoated with a special light colored material that deflects heatrays .

The suit worn by Colonel

Leonov appears to be similar tothe advanced form of a spacesuit to be used in the United

States Gemini program . In itsfinal , the Gemini suit was

supposed to provide capabilityfor short duration life supportoutside the spacecraft .

Committee of the Communistparty ( and ) the Soviet Government" that he and his co-pilotwould do their best .

Neither Mr. Brezhnev nor Mr.

Kosygin was mentioned in theastronaut's message . Previous

spacemen had always sent

their messages to Mr. Khrushchev and had praised andthanked him by name.

The astronauts sent fewermessages than in the past togovernments and Communist regimes

A special prominence wasgiven to Raúl Castro of Cubawho is in the Soviet Union . Hecame here earlier in the monthfor the conference of Communist parties .

Mr. Castro was quoted byTass ashaving spokento Col

Belyayev by radio telephone and invited the astronauts to Cuba He asked thepilot what Cuba likefrom space. and Colonel

Belyayev answered :" is very beautiful and

its green colors are lovely "

It was not clear whether Mr.

Castro was with the Sovietleaders at the Kremlin

or whether he spoke from another stationYesterday's shot was the

eighth manned Soviet spaceflight. the second with morethan one person in one craft .

Colonels Belyayev andthus are the Soviet Union

10th and 11th astronauts.The announcement of the suc

cessful launching came simultaneously and solemly andtriumphantly over all Sovietradio stations at 11 in the morning, an hour blastoff.

The announcement sald thatVoskhod 2 had enteredan orbitclose to the prescribed one . Thetwo pilots were well and conducted their assigned tasks, theannouncement said .

The live telecast of the interior of the cabin during theseventh orbit showed ColonelBelayev reclining in the left!background .

The pictures of Colonel Leonov floating in space were takenfrom a camera rigged on theoutside of the ship lookingacross the top toward the hatchThe official announcement

said that Colonel Leonov had

inspected the outside of the

ship taken movie shots andmade observations of the

earth from outer space .The announcementdescribed

Colonel Leonov as an officer

who had " studied the design of

the spaceship to perfection and

who is thoroughly prepared to

fulfill complex tasks in spaceflight.

Colonel Belyavev at 39 theoldest Soviet astronaut to have

gone into orbit . The others havebeen intheir late twenties or

early thirties.Ina reference to the colonel's

age, Tass said that it was " logical to conjecture that fewerand fewer demands are beingmade on the physical conditionof those traveling in outer

. "A Soviet expert speaking on

television later said that the

technical demands on Colonel

Belyayev on the other hand

were tremendous especiallyduring the period when he directed Colonel Leonov as heleft the cabin , moved around inouter space and re - entered thecabin .

The expert pointed out thatColonel Belyayer, as the ship'scommander . was in control ofthis operation

Constantin F. Feoktistov , thescientist who was one of threecrew members of the first Voskhod shot last October , wrotelin Izvestia last night that aprincipal objective of the flight

was the testing of methods forgetting in and out of a cabinduring flight.

In an article written beforethe experiment had taken placehe wrote that success would

make it possible to performassembly and repair work onthe ship during flight and finally to go from one ship toanother ."

His article described Voskhodhaving decompression

The chamber he wrote, hadan inside hatch that the as
