Astronauts might have problems with weightlessness, with lack of oxygen, and how to eat and rest in weightlessness.Space is а high vacuum situation, if the human body directly exposed in space,immediately due to the low pressure will lead to the loss of internal organs, blood, skin and other normal functions, directly endangering life.In addition to pressure,the human body can not withstand the low temperatures and high levels of radiation in the space.

I think the high levels of radiation,which from the sun and other stars, is the greatest danger to astronaut when he is trying to accompish a space mission.It can damage people's health badly,even their children.Otherwise,space rubbbish is thought to be agreat dangerous to the astronaut.A small piece of space rubbish may knock the spaceship window and cause great damage,affecting the normal operation of equipment.

The weightlessness of space is a big challenge . For the astronauts , there is always the constant danger of floating away into space due to the lack of gravity . What is more , the pressure of heart and blood vessels often pushes the blood to their body and head , so make them suffer from headaches . Also the space is full of harmful radiation and lack of oxygen .

If you go out of the space hatch,you will find it difficult to balance your body without gravity.Although the scenery will be unbelivablely beautiful and you can enjoy the silence alone,there may be some space rubbish floating towards you,which could be really dangerous.Aliens from outer space may find you and take you to their star.

First of all, the most dangerous problem they will meet is the lack of the oxygen, and without this they cannot breathe. Second, the radiation is also very dangerous for them, because there are full of radiations in the space ,and they can cause some diseases such as cancers. What’s more , the weightlessness is also an important problem, because lack of gravity, it will be quite difficult to walk and move in the space.

They are in a vaccum environment where sound can't be spread. So loneliness may accompany them in such a silent place. What's more, radiation does harm to their body when they are in space. If there are any leak on their suits, blood would boil, and astronauts will under the threat of death.

One of the biggest problem brothers them is the weightlessness.It is difficult to adopt to eat something and walk in the space.Staying in space,they need a special spacesuit made of some special materials to against the harmful radiation,They also spare no effort to overcome the enviorment with lack of oxygen.

1st,he lack of oxygen is fatal to astronauts. It is well known that there is a lack of oxygen in space, which is a necessity for human existence.2nd,with the development of the space exploration，some space litters were produced，this is also a security hazard.3th，there is a lot of radiation in space, which will cause harm to human body.

First，exposed to the high levels of radiation,which from the sun and other stars, is the greatest danger to astronauts even with the help of space suits.It may cause cancer and some other diseases.
Next,If astronauts fotget secure the rope on the body,weightlessness may let them get lost in space.
Last,lacking of oxygenand low pressure are also dangerous.If astronauts exposed themselves ouside immediately due to the low pressure will lead to the loss of internal organs, blood, skin and other normal functions, directly endangering life.

There's the constant danger of floating away due to the lack of gravity.Humans become weightless and can float away if not connected to something solid. If something goes wrong, such as a problem with a spacesuit, it may cause a lack of oxygen.Space is almost a perfect vaccum empty of the precious oxygen we need ro survive. There is a lot of radiation in space, which will cause a lot of harm to human body.

humans become weightless and can float away if not connected to something solid. In addition, space is almost a perfect vacuurm, empty of the precious oxygen we need to survive. It's also full of harmful radiation which can severely damage human tissue. Overall, the environment o space is extremely dangerous for humans without the protection of a space suit.

The lack of gravity is one of the constant danger of floating away.Because of it,humans become weightless and easily floating away unless astronuats connected themselves to something solid. If something goes wrong, such as a problem with a spacesuit, it may cause a lack of oxygen and it protect hunman body from space radiation.
