not feel a lack of air. Oxygen was emitted with plants
the greenhouse occupying sixteen square meters.
Plants absorbed the carbonic acid emitted to them and animals.
Here the foundation of “circulation of substances” which had to were laid
to give to future heavenly travelers all necessary for life if their flight
will drag on or on other planets there will be a lack of the atmosphere and food.
Finger and a metal sphere which comprised “a piece examined
interplanetary space”. In this sphere the double door with the camera conducted,
as in a caisson, and it was possible to enter it only in special suits,
like diving. Zander worked over these suits much. It was necessary
to create special laboratory for test of various materials which
would provide, on the one hand, almost absolute not heat conductivity, and with
another – sufficient durability.
– And it is impossible to freeze in such suits, being in world
space? – Hans asked.
– Coloring of clothes and action of sunshine can give from minus
two hundred to plus hundred and more degrees Celsius, – the laboratory assistant answered. —
Therefore fears of cold of interplanetary spaces are exaggerated.
– And it that for tanks? – Hans asked.
– Test of a surface of the rocket for reflection and absorption of beams, —
the laboratory assistant answered. – Let’s enter in this cylinder. – They entered. – Now
here it is dark and quite cool. The cylinder is turned to the sun by the
the shining, polished surface which reflects sunshine.
Let’s turn the cylinder a black opaque surface now. – The laboratory assistant turned
the lever, the cylinder began to rotate on a longitudinal axis so that to Hans and it
the satellite had “to go on one place” until the cylinder stopped.
Did not pass also two minutes as Hans felt, what became much warmer.
– You feel how the Sun heats? And on the Earth’s surface
a half of sunbeams is reflected the atmosphere. Now you look.
The laboratory assistant rummaged around in the dark and again turned the lever. Above opened
window through which the sunlight rushed. Temperature began quickly
to raise.
– The ray of sunlight is collected by a concave mirror and directed to a back wall
rockets. Turning the rocket a black or brilliant surface, we can
to change temperature in it from twenty nine to seventy seven degrees
Celsius. Applying mirrors, it is possible to melt metals. But it is possible “to fill” and
world cold. Having such wide temperature scale in the hands,
Zander designed in principle Tsiolkovsky the solar engine. Two
reported the cylinder in turn address on solar, on
shady side. In the Sun liquid in the cylinder evaporates,
which presses on the piston, in a shadow – liquid and steam are cooled.
– You needed to examine laboratories where models were tested
rocket engines, the placed in an oak frame, six laboratories on
to domestic service of passengers of the rocket.
– Whole six!
– Yes, – the laboratory assistant answered. – A question here at all not in conveniences, and in
need. We have to neglect nothing and all are obliged
to provide. In usual conditions we do not notice much, about much
simply we do not think, and about such “trifles” without which it is possible to be gone
in “sky”, or, on the contrary, which can do huge harm if them
not to eliminate.

WORTHY PUPIL OF TSIOLKOVSKY
– Zander arrived! We go to it! – Vinkler told. Hans raised the head
over the book. He was excited. Hans worked with Zander not one month. But
for the first time the engineer-inventor invited him to himself.
– What for?
– Probably, wants to get acquainted with you closer. Perhaps, to charge
some work, – Vinkler answered, and his eyes cheerfully smiled.
– Well, we go.
In Stormer-city Zander lived in a separate lodge with an attic. On a call
Vinklera was heard at first desperate bark of a sheep-dog; the door was opened, and
the old servant severely muttered:
– There is no house! – but, having recognized Vinkler, smiled as to the old acquaintance, and
told:
– Ah, it you! You enter. Wait, I will only take away a dog.
Finger guessed how there lives Zander. The office which is filled up seemed to Hans
drawings, models and all other accessories of the inventor. But it
was mistaken. The small office of Zander where it accepted visitors, was
it is arranged more than simply. A desk, two chairs before it, near
table – the small rotating shelf with books, and only. Only thing
the big portrait under glass in dark oak was decoration of the room
to frame, hanging on a wall behind the owner. On a portrait it was represented
bearded
