we consider our “neighbors” in world space, – ten – fifteen

years. Some tens of stars are from us on such close

distance. To the others it should fly hundreds and thousands of years. You

the immense desert within months, years, decades would surround.

Any concept about time will disappear.

– What star, next to the Sun? – Blotton asked.

– Alpha Tsentavra. In total about forty trillion kilometers.

– Four over a year – are not much. Having kept silent, lord Henry

returned to terrestrial affairs:

– And why, actually, for start this is chosen wild, desert

place?

– Just because it wild, desert, unsociable. Such is desire

shareholders of your wild society “Noah’s Ark”. Conspiracy.

– But there is a lot of desert places on the globe, to take at least Youzhny

pole. There nobody would prevent us, even efficient reporters. Why

exactly here? I would like to know, than the choice was defined.

– On it there were the, and important, the bases, – seriously answered

Vinkler. – Exactly there are optimum conditions for

take-off. You probably know that to the rocket at take-off from Earth

it is necessary to break through a double armor: atmospheres and terrestrial

inclinations. The greatest inclination exists on poles, the smallest – on

the equator as Earth is a little flattened to poles. Besides on

poles the smallest, and on the equator the greatest centrifugal effect.

Therefore an inclination armor on the equator minimum.

– And what difference in weight?

– On the equator the body weighs on the one two-hundredth share less, than on

pole.

– Only? – disappointedly Blotton told.

– Yes, only. Thanks to centrifugal effect and “inflation” of terrestrial

sphere at the equator of a body weigh on half-percent less here, than at poles.

As though really it is a little. But for the rocket important even it

reduction of weight: it gives noticeable economy in a fuel reserve. So

weight half-percent – not so small size in our enterprise.

– Well, equator. He agrees. But why this place on the equator?

– To answer also this question, we should talk already about

other armor – atmospheric. Air which we approximately do not notice,

represents almost absolute obstacle for quickly moving

bodies. The quicker the movement, the is more resistance. At very big

speeds resistance of air is almost also big, as well as resistance

solid body, – the real steel armor. This not only figurative

expression. Meteors – the stones which are on a silver platter – move from space

speed; crashing into the atmosphere, meteors more small, being heated because of

air resistance, evaporate, being besieged тончайшею by dust. Here with

what obstacle it is necessary to deal in our flight. Zhyulvernovskiye

the heroes who were taking off from the gun in a shell would have to in the first

the moment of a shot to break in flat cake against a shell bottom. To avoid

this sad fate, we will increase the speed of our rocket

gradually. We have to choose such place on the globe where

the atmospheric armor has the smallest thickness. Relative

density of air depends on pressure, temperature, humidity, and all
