Sport in space begins with a football in zero gravity

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

Long-term manned space missions is now impossible

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

The largest planet

Astronomical parameters

The largest planet of the Solar System, the third brightest object night sky (after the moon and Venus). Is gazaille body, hard surface does not. Consists mostly of hydrogen and helium. Due to their size can be observed with the naked eye as a star of the first magnitude, but only for a short time in the morning or in the evening. The average distance from the Sun 778 million km conversion – 314.8 years 11 days.

Jupiter has 16 satellites: IO, Leda, Teba(Phoebe), Carme, ELARA, Ananke, Europe, Metis, Pasiphae, Sinope, hamalia, Ganymede, Lysithea, Amalthea, Callisto, and Andrastea. System his companions like a scaled-down model of the Solar system. The four major satellites (Ganymede, Callisto, IO and Europa) discovered by Galileo and are called the Galilean. Continue reading
