The answers to most interesting questions.
Space has long stirred the minds of people. And those who just like to watch the sky, and those who spend time behind books on astronomy, many, seemingly obvious questions, to find answers to which is quite problematic. We have compiled the most common space a questions and found them correct answers.
1. Do astronauts wear diapers
Yes, that’s right – during the start, during return to Earth and during all the work outside the ship or space station in orbit, the astronauts wear diapers. However, the astronauts don’t call them “diapers”, and “maximum absorption garment”.
2. Is it true that in space you do not hear even cry?
So. Any sound that people can hear, this sound waves are actually vibrations in the air. In space there is no air, so there’s nothing to vibrate.
3. When the next time will be Halley’s comet?
Halley’s comet will be visible again from Earth in 2061. Interestingly, mark TWAIN was born during the passage of Halley’s comet and died during its next occurrence. During life he predicted his death, saying: “We are two inexplicable monster who came together and should leave together.”
4. When people will land on Mars?
Today, the most realistic date is 2030. One of the main problems of the delivery man to Mars are Finance. It is quite possible that the first on Mars will be NASA, but a private expedition Space X.
5. If there really “spy satellites” in orbit?
Unfortunately, Yes. For example, the recent spy satellite launched in March 2017 Japan to monitor North Korea.
6. What the names of the planets in the Solar system?
With the exception of Earth, all the planets in the Solar system were named after gods and goddesses of Greek and Roman mythology. Pluto was God of the underworld, mercury was the messenger of the gods, Venus was the goddess of love and beauty. Uranus, the only planet named after a Greek God was God of the sky. Saturn was a Roman God of agriculture, Mars was the God of war; Jupiter, the largest planet in our Solar system, was named in honor of the ruler of the gods, and Neptune was the God of the sea.
7. Is there a mysterious “planet X” in our Solar system?
It is quite likely. NASA found evidence that a planet the size of Neptune orbits the Sun even more remote orbit than Pluto. A complete revolution around the Sun it should do around 10 000 years.
8. What happens in space with a bunch?
First, they will not fly away because there is no gravity so the heavy air began to fall down, and no air flow to raise them up and to dissipate. Gaza will just hang in one place. Luckily, spacesuits are equipped with modifications for filtering gases.
9. Why does it seem that the stars twinkle?
This is because their light must pass through various gases in the Earth’s atmosphere. The principle is roughly the same as in the case of water, in which the light is refracted and makes the water “sparkle”.
10. Can the blood boil in space without a spacesuit?
Yes. It has to do with how pressure affects the boiling point of the liquid. The lower the pressure the lower the boiling point because the molecules easier to move and to turn from liquid to gas. Thus, the boiling point of blood would be reduced to the natural body temperature in a vacuum.
11. What is the temperature in space?
She really is different. For example, near stars are quite hot and matter instantly evaporates. In the depths of space is quite cold. For example, on the ISS (without thermal protection) would be about 121 ° C on the side facing the Sun and -157 ° C on the dark side.
12. How much garbage flies on an orbit?
People are incorrigible, and begin to make a mess wherever you go. There are currently over 500,000 pieces of “space junk” in Earth orbit that can cause damage to spacecraft.
13. How many space stations?
Currently there are two such structures. The international space station (or ISS) and Tiangong-1, which belongs to China. While the ISS is always manned Tiangong-1, as a rule, no. The ISS was created jointly by Russia, the USA, Japan, Canada and the European space Agency.
14. How far away is the nearest star (besides the Sun)?
Proxima Centauri is at a distance of 4.24 light-years from Earth. The best way to visualize this distance to represent the Sun and Proxima Centauri the size of a grapefruit and are at a distance of 4,000 kilometers (approximately from Moscow to Krasnoyarsk or from the East coast to the West coast).
15. Are there any other dwarf planets in the Solar system?
Just in the Solar system there are five dwarf planets: Ceres, Pluto, Eris, Makemake and Haumea. Pluto is not even the biggest of them, Eris is 27% bigger than Pluto.
