Giant leap into space exploration

How did the work of the first American expedition on the lunar surface begin? Immediately after the ship landed on the plain of the lunar Sea of ​​Tranquility, the Apollo 11 commander Neil Armstrong told the Mission Control Center via radio: “Houston, here is Tranquility Base. The eagle has landed ”(Eagle,“ Eagle ”, called the lunar ship,“ landed ”meant landing on the lunar firmament,“ earth ”, and the landing point was called the Base of Tranquility after the vast lunar plain – Sea of ​​Tranquility).

After that, the astronauts checked all the systems of the lunar module in case of an unexpected launch. Next, according to the plan, there was a dream lasting 4 hours. And here the astronauts in violation of the program asked permission to begin access to the moon immediately. It has been received. Barely touching the lunar surface with the left boot of his Continue reading

Hubble Space Telescope

From the very beginning of astronomy, from the time of Galileo, astronomers have one common goal: to see more, to see further, to see deeper. And the Hubble Space Telescope, launched in 1990, is a huge step in that direction. The telescope is located in Earth’s orbit above the atmosphere, which could distort and not transmit radiation coming from space objects. Due to its absence, astronomers obtain the highest quality images with Hubble. It is almost impossible to overestimate the role that the telescope played for the development of astronomy – Hubble is one of the most successful and long-term projects of the NASA space agency. He sent hundreds of thousands of images to the Earth, shedding light on many secrets of astronomy. He helped determine the age of the Universe, identify quasars, prove that massive black holes are located in the center of galaxies, and even set up experiments to detect dark matter.

Hubble Hubble’s discoveries have changed the way astronomers look at the universe. The ability to see in great detail helped turn some astronomical hypotheses into facts. Many theories were discarded in order to go in one right direction. Among Hubble’s achievements, one of the main ones is the determination of Continue reading

Moon exploration

It is not surprising that the first flight of the spacecraft above Earth orbit was directed to the moon. This honor belongs to the Soviet spacecraft Luna-l, which was launched on January 2, 1958. In accordance with the flight program, after a few days it passed at a distance of 6,000 kilometers from the surface of the moon. Later that same year, in mid-September, a similar Moon series device reached the surface of the Earth’s natural satellite.
A year later, in October 1959, the Luna-3 automatic apparatus, equipped with apparatus for photographing, surveyed the far side of the Moon (about 70% of the surface) and transmitted its image to Earth. The device had an orientation system with sensors of the Sun and the Moon and jet engines running on compressed gas, Continue reading
