The Human Mission to Mars: Colonizing the Red Planet
There are many other reasons to travel to other worlds and beyond besides the urge to explore the unknown. One is the obvious long term motivation to become an inter-stellar space faring civilization. At some point in the distant future we will have no choice but to leave our home world. Our sun, already a middle aged star, is powered by fusing hydrogen in the nuclear inferno at its core. As the remaining fuel is consumed, the sun will continue to expand in size and with it the intensity of the radiation increasing at the planets. Already the sun's output is 15% greater than it was a few billion years ago and eventually it will destroy all life on the planet. The long term prognosis is that the sun will expand to such a large degree that in due course it will cause our oceans to boil away into the vacuum of space leaving an uninhabitable desert wasteland behind.

Huh. Last I heard, the sun would lose mass, causing the orbits to expand, slowing any effect of a rise in solar intensity.
Also:
I'll be dead by then. I'll feel bad for the great, great to the 10th power(I wish I could do superscript in here) grandson, but his kids'll be real pricks.

Human life on Earth grows steadily more challenging as we grow exponentially in population. From territorial disputes to wars over natural resources, our species has shown, in an amazingly tribal way, that we just can't play nice. But there have been spikes in cooperation and a few of them have come about by Space programs. And not only has the goal of space exploration granted us some modimeep of solidarity between tribes, the cooperation needed for the goals met to allow human space travel has, as an offshoot, created/spurred/inspired many of the greater advancements humans have made thus far. So I say, first star to the right and straight on till morning.

humanity will destroy itself before this endeavor will be realized

really? you are concerned about this now? We have billions of years! Also the population is literally exploding... When i was a kid in the eighties there were less than five billion people on earth. this year there are to be seven billion. based on projected life expectancies for me based on factors such as family history, edumication, and income (i findz this on the interwebs) my life expectancy is 91, meaning i should die around 2076. According to fancy charts and graphs found here there will be 11 billion people in the world. I would imagine by the time the sun explodes there could be a trillion. However, I am confident the human race will destroy itself or God's Judgement will come and by the time the star explodes there will be no one here.
so my question is, why should anyone alive now give a flying meep?

Yes, but only that I may continue my perfect unbroken trend of believing fervently in the message behind every link I swarm.

I, personally, wouldn't want to live there. I hear the planet is very Angry, & Red, and has lots of critters that tell you so.
