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

Scientists warn that sex in space is dangerous for health

Future space tourists are already thinking about what it would be like to have sex in zero gravity. However, scientists hasten to cool the ardor of the lovers: sex in space could harm the health.

Future space tourists are already thinking about what it would be like to have sex in a vacuum. However, scientists hasten to cool the ardor of lovers.

According to biologists, to conceive a child in extraterrestrial environments will most likely not succeed. Space hostile to earthly love, the scientists shrug. Moreover, they say that sex in space could cause irreparable harm to human health. These words are confirmed experimentally. However, I was involved in a potentially dangerous study not people, and plants.

Their cells are damaged when the gravity changes, proved the researchers. In particular, when too high or too low gravity to the negative impact of exposed pollen tube is the vegetative cell of the male zarostka in flowering plants. Gravitational changes are not the best way affect its development and functioning.

In addition, the space environment is threatened intracellular circulation of the plant. Continue reading
