Russian space systems holding (RCS, part of the Roscosmos state Corporation) continues to publish unique historical documents from 1972 that reveal previously unknown details of the history of space exploration.
This “Russian Spring” reported in a press-service of the holding company “Russian space systems”.
Today, the company’s website published an electronic version of the 1972 document “radio Engineering complex of the automatic station” Luna-17 ” and ” Lunokhod-1 “(object E8 # 203)”, which discusses various aspects of the operation of the automatic station “Luna-17” and “Lunokhod-1”.
The document allows you to evaluate how the work was done on the errors that made it possible to conduct the next lunar mission almost perfectly.
Prepared more than 60 years ago by Soviet engineers, the document contains detailed information about the operation of onboard transmitters, antenna systems, telemetry systems, photographic equipment and small-frame television system of the lunar Rover, which became the “eyes” of its “drivers” on Earth.
In addition to its historical significance, the document is of interest from the point of view of understanding approaches to processing information obtained when using devices in real conditions. Continue reading
Solar system. Planets of the solar system
Its center is a huge star called the Sun. It is the closest star that is billions of years gives us light and heat. Without it, impossible would be life on the planet. Around it revolve the planets, of which eight are known today, as well as other celestial objects.
Schematically, the structure of the solar system is as follows:
Man is always interested in the question thus arose our solar system. But it was a long time before scientists were able to answer this question. There were many versions and assumptions on this issue. And today, astronomers are continuing their investigation.
According to a hypothesis of Kant-Laplace five billion years ago there was only a gas cloud. It moved through the universe, but at some point he undergoes certain processes. Then there is compression and then begins the rotation, the center of rotation is the fastest. The temperature at the center of the cloud began to grow and formed a protostar that later became the Sun. The nebula continued to spin, and the star are unable to absorb all the substance of the nebula, they are attracted, experienced, forming planetesimal. One of them appeared on the planet.

In the fall of 2020, after Amateur astronomers Vitaly Nevsky and Artem Novichonok first observed the comet ISON, astronomers had expected that she would become a “Great comet” − a rare visitor, perhaps the brightest comet of the twenty-first century.
Alas, severely battered during the close approach to the Sun in November of this year, ISON no longer promises such a bright future. To the naked eye from the Ground to see it would be impossible − but hopes not worth it to lose. Somewhere in the dark depths of space, probably unnoticed by anyone else is racing the comet, which will deserve the attention and present us with an unforgettable sight. This has always been the Large comets appear about once a decade, and every century one of them was especially bright.
We will tell you about these “comets of the century”, since the sixteenth century. It is interesting that they flew as a rule, in the second half of your century, and has had an average of once every 97 years. Given this, we can calculate that if the comet of Ikeya-Seki (C/1965 S1) visited the Earth in 1965, following a visitor, you can wait until 2029.
However, to predict what particular impossible: a Big comet can appear quite unexpectedly, at almost any time. The message we may hear tomorrow.
