Do I need to be perfectly healthy to fly in space?

The main problems during space flight are considered motion sickness, fatigue, dehydration, loss of appetite and back pain

The astronauts can perform on the International space station not more than six months. And for good reason.

The loss of muscle and bone mass in zero gravity during this time is so great that the continued presence in space for humans is not possible.

Future space tourists will not go through the same tough training as cosmonauts and astronauts – how flying can affect their health?

In an article published by the British medical journal, argues that the district doctors in British clinics need to be prepared for the fact that in the near future, their patients will begin to wonder whether their body to move space travel.

Only a handful of doctors have sufficient knowledge in the field of space medicine to give expert advice. Continue reading

Place the Solar system in our Galaxy

Planet Earth, the Solar system . and all the stars visible to the naked eye are in the milky Way Galaxy . which is a spiral galaxy with a jumper with two distinct sleeves starting at the ends of the jumper.

This was confirmed in 2005 a space telescope named the Lyman Spitzer, which showed that the centre bar of our galaxy is larger than previously thought. Spiral galaxy barred spiral galaxy barred (“bar”) of bright stars emerging from the center and crossing the galaxy in the middle. Spiral branches in these galaxies begin at the ends of the crosspieces, whereas in normal spiral galaxies, they come directly from the kernel. Observations show that about two thirds of all spiral galaxies have a bar. According to existing hypotheses, the jumpers are centers of star formation, supporting the birth of stars in their centers. It is expected that through orbital resonance, they are passed through a gas of spiral branches. This mechanism provides a flow of building material for the birth of new stars. Milky Way along with the Andromeda galaxy (M31),Triangle (M33), and more than 40 smaller galaxies-satellites, form the Local Group of Galaxies, which, in turn, is part of the Virgo Supercluster. “Using infrared images from NASA Spitzer telescope allowed scientists to discover that the elegant spiral structure of the milky Way has only two prevailing sleeves from the ends of the Central bar of stars. Previously it was thought that our galaxy has four main hoses “. 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
