I think that space can sometimes be dangerous as it can have an effect on your health if you stay there for a year or more and can put you in danger.
Firstly, If you go into space for more than a year you could become really weak and can cause depression from being in isilation. It would also take you some time to get used to normal life from being in space for a year. I don't think you would like to be in isalation for a year without your friends and family?
Secondly, you could have problems with your rocket and might have to crashland which could be a serious situation! It would also give you a shock because you wouldn't be expecting it. And you might have problems getting out the rocket to see where you are.
What do you think?
