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.

So, according to the company, Space Island Group, might look like orbiting the stadium. The game tourists in the ball channels could broadcast live .
Weightless — what is not a reason to invent a whole new class of sports? After all, space sports of one type or another, more than likely. Especially due to the rapid development of the private aerospace business and the increased number of space tourists. Is it any wonder that competition in zero-gravity invented today?
If we talk about professional cosmonauts or astronauts, sports games in orbit for them is obvious. Given the fact that in the future the crews of the expand, and the missions will be very long, like missions to the moon or Mars.
A peaceful “battle” with each other under conditions of zero gravity could help space travelers not only to diversify the flight, but also to maintain health, physical and mental. But for space tourists sport in space can be a great added attraction. Continue reading
The answer to the question of how in the coming years will be Russia’s contribution into the process of full exploration by the inhabitants of the Earth, not yet clear
Before the first manned flights into space, many physicians feared that in weightlessness the astronaut may be a different disease: ulcers and kidney stones, sudden weight loss, softening of bones, decreased muscle tone, the development of sea-sickness, disturbance of the orientation and other misfortunes. But in reality it turned out that astronauts in General are more or less able to adapt to microgravity and not to experience any serious discomfort, especially in flight conditions, the duration of which does not exceed 6-10 months. In order to reduce harmful effects to a minimum, the astronauts, while in orbit, exercise, diet, etc.
But how will affect the human body long-term space flight, lasting several years, physiologists have collected insufficient data.
In light of the active conversations and different messages about the future of manned human flight to Mars, which include the experiment “Mars-500” and recent statements by President Barack Obama . this information is very necessary. Continue reading
