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
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
Work on this program began in the USA in the late 60s. It was decided to carry out a man’s flight to the moon and his successful return to Earth over the next ten years. In the summer of 1962, after lengthy discussions, they came to the conclusion that the most efficient and reliable way is to place the complex in the command and computing module, which includes the command and auxiliary modules, and the lunar landing module into the lunar orbit. The first priority was the creation of a launch vehicle capable of introducing at least 300 tons into low Earth orbit and at least 100 tons into low Earth orbit. At the same time, the development of the Apollo spacecraft, designed for the flight of American astronauts to the moon, was underway. In February 1966, the Apollo was tested in an unmanned version.
