(3.84) | 2 | This book has been written to answer all the questions which the intelligent layman asks about the new science of "astronautics" - a subject which is increasingly in the public eye. The treatment, though scientifically accurate, is entirely non-technical and the many remarkable plates-four in full colour-give a vivid impression of the way in which space-travel may be achieved. Among the subjects illustrated are: the refuelling of spaceships in free orbit outside the atmosphere, the construction of a " space-station ", an automatic rocket surveying Mars, the lunar base, and dawn on the planet of a multiple sun. All these illustrations are based on a sound scientific foundation and every effort has been made to be factually accurate and to avoid mere fantasy. None of the difficulties of interplanetary travel has been shirked, and the many engineering, medical and similar problems which must be overcome before space-travel is possible are fully discussed The book also gives a clear and very readable picture of Man's place in the Universe, describing the planets he may explore during the next century, the methods that could be used to colonise them despite their alien conditions, and the ultimate effects which astronautics may have upon humanity. Quite apart from its interplanetary theme, The Exploration Of Space is thus a fascinating introduction to astronomy and combines excitement and instruction in a manner which should appeal to everyone.… (mehr) |

Bogen starter med Biskop Godwin og hans rejse til Månen vha svaner. Han forudsagde mindre tyngdekraft på Månen, hvilket var godt set, for det var 50 år før Newtons opdagelse af tyngdeloven.
Simon Newcomb skrev i 1903 en artikel om hvorfor flyvning var umuligt. I 1908 ditto om at en flyvemaskine aldrig ville kunne fremføre både en passager og en pilot.
Side 40: Ingen dødvægt må medføres et øjeblik længere end nødvendigt. En raket til Månen kræver 40000km/timen, Venus 41500.
Bogen beskriver i detaljer hvordan en flertrinsraket er påkrævet og at en sådan vil kunne skaffe os til Månen og de nærmeste planeter. Clarke nævner også muligheden for at det hele ender i en atomkrig, men han vil hellere tænke over en lysere fremtid.
Bogen er en nydelig populærvidenskabelig fremstilling af rumforskningens muligheder. ( )
