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

Cosmonaut held in Tula space debate

On cosmonautics Day, the students gathered in the TSU to discuss the most interesting “star” questions.

On the agenda of these debates were three interesting topics: “Space tourism” “Space debris” and “give a star from the sky”. All the “pros” and “cons” emotionally discussed two teams from the main universities: the University and the Tomsk state pedagogical University.

Leading the debate was inhabitant of Tula Sergey Zaletin, pilot-cosmonaut and hero of Russia. At the beginning of the meeting, he noted that the conquest of space means a lot to the Tula region:

Of the 85 regions of our country was only 120 astronauts and four of them – from the Tula region: Yevgeny Khrunov, Valery Polyakov, Nikolai Tikhonov and me. Tikhonov is the youngest of us, and in flight he is only going two years later.

I noticed an interesting pattern: Polyakov 71 years old, I’m 51, 31 Tikhonov, probably, somewhere on the Tula earth future astronaut growing up, by my calculations, he should now be 11 years old. Continue reading

Space tourism

“Look at the Earth from space” — many believe this is his dream, and I want to say that it is real. For this you will need some kind of billion. And before you the most exclusive in the world tour. Of course, tours offer only a couple of times a year and extensive training is needed, but in any case should not stop the applicant unreal adventures.

So, let’s go directly on the tour:

Space tourists go to the destination to the manned Soyuz spacecraft. Not to say that you will fly in comfort, but to the very door of the “hotel”. The flight will take approximately 6-7 hours, but the road back is shorter by almost 2 times.

Also there is another way – it is suborbital flights. You climb to a height of about 100 km 5-6 minutes of weightlessness and back to Earth. It’s not as interesting as a few days, for example, on the ISS, but still exciting and also much cheaper. The price hovers around one million rubles. Agree – it is significantly different from full-fledged space flight. Continue reading
