I have this idea and it probably would never work but it's worth bringing up.
Wouldn't it be great if the countries of the world could come together form a collective with their space agencies to explore space. Right now NASA is the big dog in the space (sorry couldn't avoid that pun), but their are other space organizations both public (governmental) and private (Virgin Galactic etc.) that could help with the work load and make space travel a possibility.
Now I know that getting countries to agree on world peace is hard enough, but it's a grand idea.
After all how can we say that there isn't or is life outside our planet if we don't go out looking for it. Space is infinite. There's so many more places for us to see. So what are we waiting for?
