Somehow it happened that I visited Kaluga in sufficient regularity, usually either passing through some of the local estate. or just cases.
Never got to walk around the city, and even more so to see the State Museum of the history of cosmonautics named after K. E. Tsiolkovsky. But once again it so happened that I had to go to Kaluga for one printing, meaning we had to ride 100 miles for 5 minutes. In the end, as in Kaluga, I got the idea to finally carry out his wish.
The state Museum of the history of cosmonautics named after K. E. Tsiolkovsky in Kaluga — the world’s first and Russia’s largest space Museum. In its creation participated personally famous designer Korolev and Yuri Gagarin. Last June 13, 1961 laid the first stone in the Foundation of the future Museum:
And after 6 years, the new Museum welcomed its first visitors. In the Museum you can get acquainted with the domestic history of cosmonautics, from the first artificial satellite of the Earth to modern long-term orbital stations. However, many of the original machines that had been in space you can see with your own eyes. Continue reading
Comets: the oldest inhabitants of the Solar system
J. L. Lagrange (1813) was also based on firmly established facts – the presence of comets that definitely move in elliptical orbits, including short-period. He explained the origin of comets gigantic volcanic explosions – emissions (eruption) with giant planets. It is, in principle, could explain the nature of the orbits of short-period comets. Subsequently, the views of La Grange shared and developed a number of scientists, among which the most important contribution of the Soviet astronomer S. K. Bo, who worked in this direction with the 20-ies to 80-ies of our century. He has eliminated the biggest internal difficulty is the concept of Lagrange – the necessity of the ejection of cometary masses (nuclei) with the “surface” of the giant planets with their powerful gravity fields, the overcoming of which requires an initial speed of 60 km/s and more. Giant planets also have thick (the length of many thousands of miles) and very dense atmosphere, in the middle of the twentieth century has been very problematic the very existence of a solid surface planets – giants beneath these atmospheres.

In addition, comets can carry the names of the people who discovered them, e.g., comet Halley, comet Machholz, comet shoemaker–levy 9 comet or Mac Note.
Movement and spatial distribution
All comets are members of the Solar system. They, like the planets, are subject to the laws of gravity, but move very peculiar. All the planets revolve around the Sun in one direction (which is referred to as “direct” as opposed to “reverse”) on nearly circular orbits that lie roughly in one plane (the Ecliptic), while comets move in both forward and reverse directions on highly elongated (eccentric) orbits, inclined at different angles to the Ecliptic. It is the nature of motion immediately gives the comet.
Long-period comets (orbital period greater than 200 years) come from regions located thousands of times further than the most remote planets, and their orbits are tilted at all angles. Short-period comets (period less than 200 years) come from the region of the outer planets, moving in the forward direction for orbits lying close to the Ecliptic. Continue reading
