Long space flights

Russian scientists in collaboration with foreign partners have classified the threats to the health of astronauts during long expeditions, including during the flight to Mars, said “Interfax-AVN” on Monday, the Deputy Director of the Institute of biomedical problems Russian Academy of Sciences Valery Bogomolov.

“Three years ago, with our international partners, we determined the risk matrix and the degree of our knowledge about these risks, the degree of protection. This list is big enough, it about 15 positions,” said Vladimir Bogomolov, commenting on sending to the ISS first annual expedition consisting of Russian Mikhail Kornienko and American astronaut Scott Kelly.

The annual flight of the astronauts arranged, in particular, in order to prepare future long interplanetary flights.

According to the scientist, it is not only about physiological parameters, for example, about the influence of space flight on the cardiovascular system, the motor area or sensory abilities.

“Takes into account such factors as the adequacy of medical supplies on Board the spacecraft for the relief of disease,” – said V. Bogomolov.

He recalled that the flight, e.g. to Mars and back will take more than 500 days. Continue reading

Spaceships in Life

Space ships that travel through.

Perhaps the most interesting objects in the Game Life almost from the beginning were space ships. It samples, which, like the oscillators periodically repeat themselves. But, unlike oscillators, they each time are shifted to a new place.

Almost 20 years in Life was known practically only 4 spacecraft. It is moving diagonally glider and three orthogonal vehicle – light spaceship (LRC), the average space ship (CCM) and heavy spacecraft (TAC). Actually ships were more an attempt to build a heavier spacecraft has led to the emergence of fleets, which, in fact, are space ships. But evidence of split fleets on familiar components (some of which can’t exist by themselves) has led to the fact that fleets are often treated as composite objects.

These 4 ships (now they are called standard spaceships) are the smallest spaceships. They very often appear in the study of other configurations or in random samples. This especially applies to the glider, which consists of only five cells. Continue reading

The largest planet in the Solar system

Equatorial diameter of Jupiter 142600 km (11 times the diameter of the earth). The period of rotation of Jupiter is the shortest of all the planets – 9h. 50min. 30C. at the equator and

9h. 55min. 40C. in the mid-latitudes. Because of the rapid rotation of this planet has strong compression at the poles. The mass of Jupiter is equal to

318 the mass of the Earth. The rotation axis of Jupiter is almost perpendicular

to the plane of its orbit (inclination of 87 degrees). The visible surface of Jupiter is an upper level clouds surrounding the planet.

Due to this, Jupiter has a relatively high albedo(0.45 m),and the details on its surface are constantly changing their appearance. From sustainable parts known Great Red spot, observed more than 300 years.

It is a huge oval formation size 35000 km in longitude and in latitude 14000 km

between the southern tropical and southern temperate bands. Color it reddish, not subject to change. Continue reading
