Pluto flyby: what does it really matter

Yesterday for the first time in history a space probe encountered Pluto and its moons at the outer reaches of the Solar System. It is an incredible scientific accomplishment, but what does it matter, really? What does it really mean? It has made me reflect a bit...

Consider this, the total cost of the New Horizons mission to Pluto was 700 million USD. Just a few months ago I read that obesity costs the UK government 47 billion GBP (~75 billion USD) per year. This means that if people lived a healthier life we could explore the Solar System many times over.

Now, the world’s expenditure in war and military just in 2012 was 1.7 trillion USD.

Imagine if there were no wars among nations, no inner conflicts. Imagine if there was no need to spend in military and this money could be invested in research and development. The things we could have accomplished already. Only one country has sent space probes to all the planets, but there are 196 countries in the world. We could have right now hundreds of satellites orbiting all the planets, rovers in the moons of Saturn and Jupiter, even perhaps a research institute permanently based in the moon. We could have surely eliminated poverty, reverted climate change, transitioned completely into clean energies, eradicated terminal diseases, expanded the life expectancy and well-being of people beyond the century.

Sending a space probe to Pluto is certainly an amazing accomplishment… but just for those scientist and engineers involved in that mission. I think humanity as a whole cannot take credit for this. Not yet.
