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

NASA will launch a sailing probe to asteroid

The U.S. space Agency plans to launch a probe, equipped with a solar sail. He will leave earth orbit and go to the distant asteroid due to the pressure of sunlight. Like the ships of the discoverers of the 15th century, in 2018, a small space probe will unfurl the sail and start a journey to a faraway asteroid, marking the beginning of a new phase in space exploration.

The idea of using solar sails for space flight was proposed almost a hundred years ago, Soviet rocketry pioneer Friedrich Zander. It was based on the fact that Photons of light can exert pressure on the illuminated surface, giving him his momentum. Therefore, if you expand behind the ship a giant mirror, his speed will gradually increase without using fuel.

However, the first experimental devices were established only at the very end of the twentieth century. This is because space sailboats should be very easy, and their embodiment in life became possible only after the emergence of a truly compact electronics. Continue reading
