True courage is required in order to be the first to go to the forefront of progress, and astronauts are the most brave people on Earth. Thousands of people devote their lives to join their ranks, but only a few succeed – the smartest, healthiest, most intelligent and able. And all because the work of astronauts involves incredible difficulties.
No one died in space in the history of space exploration. Accidents were, but they all occurred either when starting from Earth, or when descending from orbit. All the dead astronauts died in the atmosphere.
During the day, the sun rises in orbit sixteen times, so the cosmonauts adhere to the conditional “earth time”.
Staying in weightlessness significantly reduces the amount of calcium in the bones.
On the orbit, the growth of astronauts increases on average by 4-5 centimeters, since the spine, which is no longer affected by terrestrial gravity, straightens.
Many products cosmonauts use only in liquid form, from tubes.
The cosmonaut, who spent the most time in orbit – Valery Polyakov. His record in 438 days is still not beaten.
The longest continuous stay in space is 14 months. This record also belongs to Polyakov, who all this time spent on board the Russian orbital station “Mir”.
Most cosmonauts initially suffer from a “cosmic illness” caused by a state of weightlessness. It is expressed, first of all, in nausea and dizziness.
Astronauts from the “Apollo-11”, who visited the Moon, on their return passed the customs control. In the customs declaration they wrote down, “Cargo is moon bullets and stones.”
The astronauts aboard the ISS wake up and stand up at the signal sent from the Flight Control Center on Earth.
The astronauts who snored on Earth do not snore in space.
After returning to Earth, many cosmonauts find it difficult to get used to the fact that the objects fall down, and do not continue to hang around, if they are released.
When brushing teeth astronauts have to swallow foam from toothpaste, so they have a special paste, conditionally edible.
