Mysterious companion. Previously, the Earth had a twin - a planet called Theia. Its dimensions were approximately equal to the size of Mars. But Theia crashed into the Earth. Most of the planet was absorbed by the Earth, and the remaining part flew away and got stuck in orbit, thus creating our Earth's satellite - the mysterious and magical Moon.
Sky sailors. Astronaut is a compound word formed from two ancient Greek words “astro”, meaning “star” and “naut(es)” - sailor, swimmer. So literally an astronaut is a star sailor. Or rather, a star swimmer. How is he different from an astronaut? Cosmos in Greek is an ordered world, the Universe. So the astronaut is the sailor of the Universe. By the way, the word “astronaut” appeared much earlier, and old explanatory dictionaries, when interpreting the word “cosmonaut,” refer to “astronaut.”
Space prices. A space suit costs between 11 and 15 million dollars - not cheap. The price may be higher, it all depends on individual programs and goals.
By the way, the first space suit SK-1 appeared in the USSR and was used in 1961-1963 for the first flights on Vostok spacecraft.
Thunder and lightning. Thunder is the sound that lightning makes. Light travels faster than sound, which is why we see lightning before we hear thunder.
