If you had a chance to go on a trip to Mars, would you - why or why not?

This is an amazingly difficult question to answer. On the one hand, it should be a non brainer - if offered, I would love to have the opportunity to go where no person has gone before, create history and be part of the team that creates hope for the survival of the human race when planet earth can no longer sustain us. I would love to build a future for our next generations, and I cannot think of a more noble goal that is also so thrilling and exhilarating. 

And yet, I also flinch from the thought of leaving my loved ones behind. Is it selfish of me to try and solve larger issues where I am a mere cog-in-the-wheel, and run away from the real issues that I can actually solve for my family? Am I being impractical or idealistic, especially when I may never see my family in the real world again - both because of the time it would take for a return journey and the risks involved.

I dare say, I am glad I don't have to make this decision, just yet!
