Planets of the solar system.

Solar system – 8 planets and over 63 of the satellite, which are opened more often, several dozen comets and many asteroids. All cosmic bodies move in their precise directional trajectories around the Sun, which is 1000 times harder than any body in the solar system combined. The center of the solar system is the Sun – the star around which orbits the turning of the planet. They do not emit heat and not light, but only reflect the light of the Sun. In the solar system now officially recognized as the 8 planets. Briefly, in order of distance from the sun, we list them all. And now a few definitions.

A planet is a celestial body that must satisfy four conditions:

1. the body must revolve around the star (for example, around the Sun);

2. the body must have sufficient gravity to have a spherical or similar shape;

3. the body should not be near its orbit of other large bodies; Continue reading

Open planet in honour of Day of Astronautics

One day in April Gagarin made his flight, and today we are on such a universal scale occasion will transcend time and space.

Time is not linear, reality is relative, and can simultaneously be in two different places. To prove it, in our current cultural ranking, we sort of go back in time to learn about the future. With undying love for “the Martian Chronicles” and warm memories of childhood on the theme of Kir Bulychev’s works we decided this time to make more distant and mysterious space journey, revealing along the way a couple of other unknown planets. So, the first point of our sci-Fi trip -1938 year.

The asteroid Vesta, around the Main asteroid belt

In earth time: 1938

Discoverer: Isaac Asimov, “In the thrall of Vesta”

What happens:

Three space travellers, survivors in the crash of a spaceship. Three airtight rooms, one spacesuit, three days ‘ supply of oxygen, a week’s supply of food and a year’s supply of water… Continue reading

Flight to Mars

Flight to Mars is planned by several countries, who are ready to launch to the red planet manned spacecraft within the next 30 years. However, despite such promising prospects, scholars continue to argue about the feasibility of such a flight.

You should start with the fact that one-way flight will take on a variety of calculations, from 7 to 9 months. Such a long flight is very dangerous as the technical side (increasing the probability of hardware failures) and physiological and also the psychological side. Will the astronauts be so many months in a confined space with very limited contacts? How will it affect the human body for long periods in a weightless condition? How great is the danger of radiation in interplanetary space? All these questions become very relevant in the context of emerging in a not too distant future flight to the red planet.

However, should carefully consider possible consequences and unforeseen circumstances that may confront astronauts involved in such a long expedition. First of all, you should bear in mind that absolutely not possible to interrupt the mission due to any circumstances, or to deliver to Mars new reserves in case of shortage. In this case the crew can only rely on their own strength. Continue reading
