I believe that space travel should not be one of the priorities of mankind. CMV

I think that space travel is an interesting concept, and I don't argue against learning more about outer space, however when I hear people complain about NASA's budget I just don't see what all the fuss is about. I mean, why should governments, whose main priority is to benefit the people and their respective nation, be forking over money to travel to places that will do little to benefit Earth (Although I do agree that many governments should top spending as much on their militaries)

This probably comes down to personal preference, but I also think that the places we have the potential to go to in space aren't very interesting. If we really want to explore the unknown why not explore the deep ocean, that would be less expensive and we would actually see new species, while we probably won't find anything as interesting in our solar system. 

Ultimately, I think that we should focus on our own planet before others, but I am open to arguments as to why we need to travel into space.

There's lot that the space program(s) can do and has done to benefit folks back here on Earth:

* Detecting near-earth asteroids from orbit. As our sensor technology has improved, there are now proposals for placing a satellite in orbit around the sun to look for potential Earth-bound asteroids. This may give us a chance to attempt a deflection or prepare for an impact.

* Space-based services for Earth. GPS, Satellite TV,  Satellite Phones, Satellite Internet/data, Satellite photos. All of these things have been made possible by the launch capability developed for the space program (and the military) and all of them have major applications on earth. GPS has become the 'stealth utility', synchronizing the clocks at cellular telephone sites, providing a high-resolution timing signal for electronics labs and providing location data for innumerable applications. Many broadcasters turn to satellites for up-linking their programming to distant locations. Satellite phone and data allow men and women to connect to the outside world in the most distant of places on Earth. 

* Development of new technologies. The space program has historically caused a number of talented engineers to solve difficult problems, some of which might have applications back on earth. This can run the gambit from advanced materials that can withstand the rigors of spaceflight and re-enter to the Apollo program's demands of compact computing equipment and the semiconductor industry.
