If you haven't seen it, I suggest you watch the anime series Astra Lost in Space.

As it actually paints a pretty realistic picture about space travel and some of the problems you can and would encounter.

The main factor that you would encounter is food. There's virtually no way to tell if the substances on another planet would be considered edible to us.

And even if they were, we have no idea what the long term effects from eating them would be. We could potentially develop entirely new diseases from consuming something from another world, or possibly develop conditions that aren't so easy to treat.

Thats one of biggest downsides to traveling outside our world, as evolution is totally different on other planets so even if you could leave earth, there is no way to be certain that you could survive there due to the vast differences in environment and development.
