Everyone is missing the fact that even if this technology was available 100 years ago, and worked just like we wanted, you could not get to Mars in 39 days. It would take about twice as long, because you have to turn the ship completely around half way to the destination and slow down pretty much for the same about of time it took to get to whatever velocity.

And Mars is a rock. I am sure there are astounding discoveries to be made, but resources would be far better spent fixing ourselves and what we've done to the planet before we cause our own extinction. Maybe we can do both, but let's not ignore the fact that we have major problems, and it is unlikely we'll ever find a better home than Earth.
