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

Brown and Batygin told about the discovery of the ninth planet of the Solar system

Scientists shared their impressions

21 January 2016, two scientists from the California Institute of technology, Professor Mike brown and Professor Konstantin Batygin has officially announced that they have found a ninth planet in our Solar system. According to their mathematical models, it is a gas giant like Uranus or Neptune, the mass of the discovered planet 10 times the mass of Earth, it rotates in an orbit 20 times larger than the earth and it requires from 10,000 to 20,000 years to make one complete revolution around the Sun. However, very reliable model of scientists has demonstrated and existing telescopes have not yet managed to see her.

Scientists have been very mixed on the nature of their activities and perhaps that is why they have achieved such amazing results. So brown has increasingly resorted to methods of observation and explores distant objects in our Solar system, whereas Batygin relies more on the laws of physics and mathematical calculations. Apparently, that tandem allowed the researchers to calculate the so-called ninth planet. Continue reading

Short-term space flights of man

Manned flights on the orbital stations

In the first decade of the era of manned spaceflight duration increased from 108 min to 18 days. Made in this period, medical and biological research (in the Russian ships “Vostok”, “Voskhod”, “Union”; in the U.S. project “mercury”, “Gemini”, “Apollo”) have proved the possibility of relatively short-term (up to 2-3 weeks) stay safe man in the space flight environment and active activities outside of the ship.

The most significant changes in the major systems of the human body were observed after flights. They were shown to decrease the body’s resistance to physical and orthostatic stress; impaired coordination of movements and regulation of the vertical posture; a reduction of body weight, hydration of the body, decreasing the volume of blood plasma and erythrocyte mass; asthenia. These changes in General increased with increasing duration of space flights and after flights, lasting 14 to 18 days, were practically significant.

Post-flight revealed improvements of indicated that to further increase the duration of flights you need to apply a system of appropriate protective and preventive measures that will facilitate adaptation of the human body to terrestrial conditions after the completion of the flight.
