Achievements in space exploration

Many thousands of years ago, looking at the night sky, a man dreamed of flying to the stars. Billions of shimmering night luminaries made him carry away the thought into the boundless distances of the Universe, awakened the imagination, forced him to think about the secrets of the universe. Centuries passed, man gained ever greater power over nature, but the dream of flying to the stars remained as unrealizable as thousands of years ago. Legends and myths of all nations are full of stories about flying to the moon, the sun and the stars. The means for such flights offered by the folk fantasy were primitive: a chariot drawn by eagles, wings attached to the hands of a person.

In the 19th century, a fantastic story appeared by the writer Jules Verne “From a cannon to the moon”. The Continue reading

Big Big Bang Challenges

Upon careful consideration, the cosmological theory of the origin and structure of the universe begins to crack at the seams.

Take a look at the starry night sky. How did all these countless stars and planets come about? Most modern scientists are likely to answer this question by referring to one version of the Big Bang theory. In accordance with this theory, at first all the matter of the Universe was concentrated at one point and heated to a very high temperature. At some point in time, an explosion of terrifying force occurred. In an expanding cloud of superheated subatomic particles, atoms, stars, galaxies, planets gradually began to Continue reading

Moon surface

The main types of geological structures on the moon are continents and seas. The dark sea surface occupies more of the visible side of the moon, and is practically absent on the reverse side.

Moon surface
MATERIALS form the upper part of the lunar crust, the composition of which is from anorthosites on the surface to dunites and troctolites at the base of the crust. The thickness of this crust is estimated from a network of seismometers left by the Apollo on the Moon and recording the passage of waves from endogenous and shock moonquakes.

In the center of the visible side, the crust thickness averages 60 km, in the areas of the Nectar and Vostochny seas it increases to 80 – 100 km, and on the reverse side it can reach 100 – 150 km. Continue reading
