Hi friends steemit

I have mentioned some facts about outer space in the former Post-Click to read

Today we will continue to talk about the facts that you may know for the first time

4- If you want a romantic vacation in space, keep in mind that you will not be able to have sex

It is better to keep your dreams rosy on Earth, so practicing outside is highly unlikely

The idea of a romantic vacation in space may, of course, seem like a fantasy, but even with enough advanced technology to make it available, sex in space is completely different and impossible, regardless of the tragic situation that will occur in the event of saliva and other body fluids. Everywhere, being in small gravitational conditions means low blood pressure in the body and inadequate access to the penis, making erection impossible

However, if this happened and it was possible in some way, it would be better to use a contraceptive to prevent pregnancy. Research on mice showed a failure in the development of embryos under weak gravitational conditions, and it would not be different in humans.

In any event, a few hundred kilometers away from the surface of the Earth is not a truly suitable situation for pregnancy or for any health complications

5- Being an astronaut requires an ideal view, but it will not necessarily remain so

Going for space is not the best choice for the health of your eyes

When outside the Earth, there is an important element lacking in addition to gravity, the atmosphere. In addition to the importance of the atmosphere to breathe primarily, it acts as a filter for ultraviolet radiation and prevents entry of most of them and reach the surface of the earth.

Unfortunately, this is not the case in the space where you will be exposed to these rays permanently and even with preventive methods Long-term exposure for more than one month will cause permanent damage to the eyes and look

6- A human base on the moon will not be easy

Space rules on the moon are a long-standing dream and a common element in science fiction movies, but in reality it is still far from being achieved.

The idea of creating a human base on the moon has always been a dream, even though it is far away. But it has accompanied humans for a long time, and every time the rumors about a government's intention to build a lunar base before a date are renewed.

But as with all previous rumors, it is possible to bet that it will not happen in reality, at least not any time soon. The problem here is not really logistical. The main obstacle is not the problem of making the materials needed and their mission to the moon. Least), but the biggest problem is "moon dust"

Moon dust is a very dense powder, very soft and highly adhering to materials. In addition, it is highly capable of scratching and gets the first enemy of astronauts on the moon. During the Apollo trips to the moon several times the powder was suspended on astronauts' uniforms in a sufficiently dense To stop their movement almost completely, and with frequent friction was able to drill through and penetrate three layers of material manufactured for astronauts shoes and similar to "Kevlar" (the material used in bullet shields)

7- The orbit around the earth is full of rubbish, and soon it will end up in danger

Many of the ISS is forced to change course to avoid colliding with the tons of waste currently circling the Earth.

When you look at the sky during the night or the day, in the clear weather the sky looks empty and the earth's orbit is empty of some artificial satellites that may occasionally shine. But the orbit is not really empty, it is rather dense, but not by satellites or Space stations, and even more than 5,500 tons of space debris distributed over 600,000 pieces of earth spinning at high speeds

This may not seem worrisome to you because you inhabit the Earth's surface and not the orbit around it, but this "space trash" is becoming a very serious and serious problem. As it increases every year, it increases the threat of satellite or even worse: International.

Although a shock from a piece of metal with a mass of only 100 grams may seem unsafe, when these metal pieces run at orbital speeds, they are like shells that can destroy or cause great damage and may be irreparable.

8- If you leave the solar system, you probably will not return to it

It is important to note that this diagram is just an illustration of the parts of the solar system and the dimensions and distances are never realistic and completely outside the scale.

With the manned flight to the moon at the end of the 1960s and the ambitious plans for a manned flight to Mars, the ideas of exploring space outside our solar system may be a future step, but later and very far away.

However, if we plan to send a manned flight outside the solar system, do not expect it to go back to earth. In contrast to what might be thought of the Earth being our solar system, it will remain in place waiting for us to return.

This is due to the fact that the sun, along with the entire solar system, is not actually in place, but is moving within the galaxy, orbiting its center at a speed of more than 800,000 kilometers per hour, and with a maximum speed of 265,000 kilometers per hour. Jupiter's great attraction, and if we do not get very high speeds in the future, order out of the solar system and return to it as in science fiction will remain in place: "science fiction."

9- The movement in space is not as slow as you think

Slow and cartoon-like astronaut movement comes because of extreme caution about any damage or sudden failure, not because the movement can not be fast.

We've all seen a film about space, perhaps or documentary about landing on the moon or even on the ISS, and there's always something constant in the subject: astronauts and almost everything else seems to be moving slowly! This will make many people think that the movement in circumstances of no gravity may be so, but in fact it is quite the opposite! Movements are generally significantly faster than on Earth

On the ground gravity plays a big role in slowing our movement and moving almost everything, but in conditions of zero gravity, we can continue to move longer distances and get to a greater speed with less effort, which means that movement in space is faster than on Earth, but what happens is that Astronauts are very careful to move quickly so that they do not collide or suffer any emergency, and this additional caution makes them move much slower than possible

The topic is too big and we can not talk about it in one post

Therefore, we will deal with other posts in which we complete the subject
