What is the most dangerous thing in the universe? Maybe you never thought
In space, you are in a closed ecosystem and must provide all human necessities. On earth, many things automatically take care of us. The same reality exists for submarines lurking deep in the ocean, providing a life barrier for protecting its inhabitants from the surrounding world. If the spacecraft joining the space is damaged, the air will leak and you will complete the game. Similarly, the submarine is also damaged, water will enter, and you will complete the game. When you are deep in the ocean, you can only rely on yourself and your companions, even in space.
Everything must be able to bear, you can not go home, you can not go to the hardware store, you can not repair things with some parts not brought, you can only use human wisdom. In outer space, you are indeed far away from human beings. This kind of loneliness is something you have never experienced before! In general, our efforts to explore space have always been compared with the great explorers of the 15th and 16th centuries. We crossed the ocean for the first time, discovered the New World, and brought all the supplies. I don't know if I can come back. But there is a big difference. When Congress signed an agreement in South America, when Columbus arrived in the Caribbean, did he still have breathing air? There are fruits on the tree. Imagine that Apollo 11 astronauts Armstrong and Aldrin landed on the moon. What if the engine is broken? At this moment, there seems to be nothing to do, only to wait for death, there is no engine tree for them to choose parts to repair the spaceship. Therefore, aerial exploration is far more harmful to human health than the journey around the surface of the earth.
There will be no gas stations in space. If you fail, you will cut off the oil. Maybe you want to drink something, it will be fatal. One of the challenges of space exploration is that you must carry all the items you need, water, food, oxygen or find some way to make it on the way or destination, but we have not yet reached the target level, we still don’t know what to do. Therefore, a risk is that if there is a problem, you will have no food, water, and protection facilities, then it will break down and you will be finished.
Every drop of water is precious. In space, there is no shower. The only option is to use a damp cloth. In fact, it requires 130 gallons of water per day. The food you bring will be similar to the food you rested with. In a few days, you can eat fresh vegetables, carrots, apples, etc. But for longer tasks, although you must use food for storage, you must ensure that the food does not deteriorate for a long time! However, the astronauts agreed to bear countless risks and witnessed the wonders of the universe at a small cost. In space, you can cover the earth with your thumb, just like giving yourself a new perspective. This blue glass ball, how amazing the earth is, how precious it is in this huge solar system!
