Space is a dangerous place and it could be unnecessary to go back their, their are some reasons why we still keep going their: It protects us from asteroids, It safe guards our health andit gives us information about things outside the earth.
You may ask , what's the point of knowing things about other planets? Well, as you know we are trashing the earth by using cars and carbon emissions erode the ozone layer making global warmingand the sea level rising so why shouldn't we expand our knowledge to learn about other planets if we ever have to move to one in the future?
There are many good reasons to continue in space exploration, which most people have probably heard. Some have been debated and evaluated on the basis ofmoney. Why go back to space when you can be going somewhere on earth? Well I would answer that by saying: Space is a never ending wonder that we could explore and investigate and give us all thrills and information that could be life saving.
Why not want to go back to space: It is dangerous, It costs loads of money, It is life endangering and it could potentially be a complete waste of time.Space has no air and you would have to travel in large bulky space suits and use dried food as it is the only food that they can bring up there.
Here is a question I would like you to answer in the comments: Why would you like to go into space and what would the pros and cons be to do so?
