9、 TEXT A/BAn airI iner travel I ing from London to New York may take from five tof i fteen hours to cross the At I ant i c,while a space capsule makes onecomp Iete circuit of the earth in about n i nety minutes.The sequence ofevents is very sim ilar in both types of fIig h t:the vehicIe must takeoff,
10、c I i m b to a su i tab Ie hei ght,fly in the r i ght d i rect ion at a relativelyconstant speed for an appropriate time,descend,and land at thedest i nat i on.Yet a I though fl ights to New York are rout i ne affairs whicha I most anyone may safe Iy undertake,a f I i ght into space is a hazardousad
11、venture for which only a few seIected men are at present consideredsuitable.The most obvious difference between an aircraft and a space vehicIeis that of speed,but this alone cannot account for the greater staminarequired of astronauts.The human body is unaffected by speed alone andwe are norma 11 y
12、 quite unconsc i ous of the earth1 s rotation on its axis,or of its rapid motion around the Sun.Of much greater importance is therate at which the final speed is achieved,for the body is extremelysensitive to alterations of veIocity,or accelerations,especially ifthey are sudden.An airI iner can take
13、 a comparatively long time to reachits cruising speed of,say,400mph,and its passengers wi11 experienceacceleration only to a mi Id degree.The space capsule,however,must behurled through the atmosphere to reach its final speed of 18,000 mph asquickly as poss i b I e,and the acce I erat i on app I i e
14、d by the I aunch i ng rocketmust be correspondingly high.The firs t problem of manned space fI ight,therefore,is to match the performance of the rocket to the body1 stolerance foracceleration,and this naturally invoIves a study of the physiologicaleffects of acceleration.Like al I other acceleration
15、s,gravity acts upon objects to producea force,and this force is experienced as weight,or as pressure.It isusual and convenient to regard the earth1 s gravity as a standard unit,referred to as Ig,and also to use the expressions MforceM andacceleration as interchangeable.Most of our knowI edge of the
16、phys i oIog i caI effects of accelerationhas come from studies on human centrifuges,in which acceleration isproduced by rotation instead of by changing speed.It has been found thathuman tolerance is greatly affected by the direction in which the forceacts.When the acceleration is appI ied in I ine w
17、ith the long axis of thebody,the early symptoms are merely of d ifficu lty in liftin g the armsand legs,and of being thrust down into the seat.If the accelerationis raised to 3g or so,vision becomes sIightIy misty or veiled.As thestress is increased further,the field of view contracts from the edges
18、,unti I at about 4.5g only a smalI patch of central vision remains.Withyet higher accelerations,even this smal I area is lost,and this is thestate we 11 known to fighter pi lots as Mb I ack-out.Finally,at about 5.5gto 6g consciousness is lost.The remedy fo11ows logically:if tolerance depends upon th
19、e ab ilityof the heart to push blood to the head,it shouId be possible to reducethe load by shortening the distance between heart and brain.Crouching,or bending the head forward,would be one solution,but an even moresatisfactory result can be achieved by placing the body across the I ineof thrust.Th
20、e effort needed to pump blood to the brain is then quitesma11,for the heavy fluid does not have to be I ifted very far.In thisposition men have,withstood an acceleration of 17g for a period of threeor four minutes without loss of consciousness.Gravity and acceleration become important once more duri
21、ng there-entry of the space capsule through the earth s atmosphere.In thisphase,al I the speed acquired at the cost of so much fuel during the I aunchmust be lost.Deceleration has exact I y the same properties andphysioIogicaI effects as acceleration,and the same precautions must betaken to avoid ex
22、ceeding the I imits of tolerance.This is why the Amer icanplan invoIves turning the whole capsule round shortly before re-entry,so that the man is again pressed back into his protective couch.The highest,and shortest,deceleration of the entire fIigh t comesat the moment of impact with the land or wa
23、ter.Here the last remnantsof the speed must be lost very suddenly,and forces of up to 30g can easi lyaccompany descent to an unyieIding surface.The duration of this finalinsult is so short,however,that its physioIogicaI effects areneg Iigib Ie.No doubt the astronaut would regard the jo lt as a we I
