Notes
Some of the challenges humans face in space is no air, the freezing environment and not enough fuel.
Also in space you never know what planets and dangerous creatures out there in the galaxy.
You have to wear a space suit and helmet with the tanks of air filled up to the top and maybe a few other astronauts.
My Thinking
I wonder how much life is actually out there?
I wonder how many planets are in space?
I wonder if they will make people able to live on mars.
