I would love to go to mars for a vacation
I would need to know more.  I read that Mars has seasons similar to Earth.
Well that is good. What else can you tell me about mars?
There is evidence of water previously on Mars making it acceptable for life forms.
So Mars is actually inhabitable?
There were two missions to Mars to determine if evidence of life could be found.  Unfortunately they didn't find anything.
Oh ok so I guess my vacation to mars is just a dream for now
Probably so.  There's mounting evidence that are muscles atrophy and change during the flight in space.
That is not good and sounds dangerous to me
Definitely sounds dangerous.  Space flight has negative effects on our bodies.
