The triumph and death of the lunar Rover

The triumph and death of the lunar Rover

Russian space systems holding (RCS, part of the Roscosmos state Corporation) continues to publish unique historical documents from 1972 that reveal previously unknown details of the history of space exploration.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.

NASA has selected six volunteers for an experiment to simulate a flight to Mars

A scene from the upcoming film “the Martian”.

In the United States selected an international team of scientists from six volunteers to participate in a new experiment simulating conditions on Mars. Within 365 days they will be completely isolated from the outside world on the slopes of a sleeping volcano Mauna Loa in Hawaii, which resembles the landscape of the red planet.

This is the fourth such experiment in 2020. The first two groups was in seclusion in self-contained complex in Hawaii for four months, the third managed to survive in isolation for up to twice as long – eight months. New group aims to raise the bar, “duration of survival” in the conditions simulating the Martian, to a new level. By the way, the experiment begins next week – August 28.

“The longer becomes each mission, the better we understand what are the risks from space travel,” said scientific project Manager Kim Binsted.

The organizers of the experiment hope that it will help to prepare the first manned Martian mission, which, according to estimates of NASA, will take place in 2030-ies. Continue reading
