HAVE THE MAN WALKED ON
THE MOON?
PARTE II: WHY DID NOT THE
SOVIETS GO TO THE MOON?
artticle published on 26 October 2020
From the short presentation of the space
missions conducted by USA and USSR, in Part
I, one can notice that, generally speaking, the results are similar. Both powers achieved significant results in
the Space Race. During the beginning period, the Soviets had a lot of successes
and were on the top, taking into consideration their achievements: first
satellite, first man in space, first astronaut outside a space ship and so on.
Lately, the gap was closed. The Soviets have kept the supremacy in Venus
exploration, while NASA has focused on Mars, where they have performed
amazingly. The Soviets succeeded to get close enough to Halley Comet and collected interesting information. Although they
did not send manned ships to the Moon, they intensely explored it, including a
remote rover landing (Lunohod 1) which
was active 11 months.[1] The
Soviet scientists’ achievements were on the same level with the US scientists’
ones. It is necessary to add that nowadays, NASA uses Russian rockets, even
based on Soviet projects, to perform space missions. Both powers also suffered
major failures: aborted missions, explosion of rockets on the pad or in the
air, death of astronauts and so on. In main, one can assess that it is
difficult to make a statement about the Space race winner: USA or USSR? But
this is less important. All I mentioned above bring up a question: why did not the Soviets go to the Moon?
The
answer is quite simple: Van Allen radiation belt. What is
this? The Van Allen radiation belt is
a zone of energetic charged particles, most of which originate from the solar
wind. The particles are captured by and held around a planet by that planet’s
magnetic field. It surrounds Earth, containing a nearly impenetrable barrier that
prevents the fastest, most energetic electrons from reaching Earth.[2] The
main constituents of the belts are believed to come from solar wind and cosmic
rays. The belt is divided into two belts - outer and inner. The inner belt
extends from roughly 600 miles to 3,700 miles, that is, from 1,000 km to 6,000
km above the earth's surface. The outer belt extends from 9,200 miles (15,000
km) to 15,600 miles (25,000 km) above the surface.[3] The
Soviet scientists assessed that the living things were not able to resist the
radiation beyond the Van Allen radiation belt.[4] And
the medium distance between Earth and Moon is 384,000 km.
What
happened? During the beginning period of the Space Race, the Soviets launched
space ships whose ”crews” consisted of animals and plants and they noticed that
the living thing could not survive beyond the protection provided by magnetic
field of Earth. Additionally, US physicist James A. Van Allen discovered the
radiation belt in 1958. In honor of him, the belt was named Van Allen. The Soviets missions
programs’ leaders did not risk sending astronauts beyond the protective shield.
They did not have the technology for this.
By
studying, as much as I could, the Soviet and Russian articles regarding the
manned ships lunar landing, I noticed they did not directly contest the success
of lunar landing and the presence of men on the Moon. On the other hand, they
also did not support this matter. They merely provide information about cosmic
radiation and the danger posed by them, Van
Allen belt and the impossibility of living thing to survive outside its
limits.
