NASA Unveils Strategy for Return to the Moon 377
mknewman writes to tell us that NASA recently announced plans to build a permanent base on the moon by 2024. The (still tentative) plans call for building the base on one of the moon's poles, which constantly receive light from the sun and have less temperature fluctuation. This base will start small in 2020 and grow over time with the hopes of eventually supporting 180-day stays and providing a jumping-off point to Mars."

As someone who finished watching "From the Earth to the Moon" [imdb.com] earlier tonight, I can say that I can't wait for humans to return to the moon. We do need a permanent presence on the moon, for many reasons, such as; separation of the human species in case of global tragedy, explore moon's geology (where did that thing come from?), explore theories about colonization, biospheres, and self-sustenance, launch point for future missions to distant worlds (if we could build a manufacturing center on the moon, its 1/6th gravity would be very beneficial to launching new craft), and many, many, many more benefits both seen and unseen.
Returning to the moon is in humanity's best interest, and is clearly the path to the future. Focus on the space program will push development and inventions to help push the edge of what is capable. I see space travel as one of the grand challenges we will face in our lifetime, and it would be a shame to hesitate when we have already taken so many steps toward that goal. As someone who was born prior to the last Apollo mission, I feel it is a crime that we have abandoned the moon for the majority of my lifetime.

sorry, that was pretty polemic. Your post and the rating it got show however, a lack of understanding of both physics, and the process of scientific discovery and eventual engineering.
A quick google search reveals tha the distance of pluto (presumably average distance) is 5.4 light hours. A light hour is the distance light can travel in an hour. It's also the shortest possible time anything can get from point a to point b as dictated by the fundamental limits of the universe as best we currently understand them. So travelling at the speed of light, which we are so very very far away from being able to achieve, we could get to pluto in 5.4 hours. For frame of reference, the fastest manned spacecraft to date is appolo 10 at 11000m/s (3.7e-5 c, a pretty impressive feat actually).
What are the issues facing high speed space travel?
First off you have the limitation of the speed of light. It might be there is some fancy sci-fi solution to this limit, but we don't even have a theoretical idea of how to approach the problem, so until there's a major revolution in physics (it could happen, it does from time to time) you're stuck with it.
A second issue is the problem of the energy required to accelerate a body to sufficiently fast speeds. This is the issue your Heim reference addresses. Well, another consequence of relativity is the mass of a body increases as you accelerate it. This means that the closer we get to light speed, the more force required to accelerate a given body by the same amount (f=ma, but a=a(v)!). Practically speaking this imposes another limitation on the speed we can accelerate to. To keep it simple, lets say we it really is possible to use this Heim stuff to overcome the limits of the rocket equation (extra mass for extra acceleration, yuck!). Well great. But we still don't even understand the theory properly, let alone have a working prototopy, so that's years and years away, and because of relativity we probably can't hope for better than ~.001c as maximum speed. That means 5000 hours at max speed to pluto.
But we haven't addressed acceleration yet, which is my point 3: The human body can only withstand so many G's (1g = earth's gravity, a unit of acceleration, 9.8m/s^2). the space shuttle accelerates at 3G which uncomfortable but doable (note that special materials were developed as part of the space program to reduce the impact of acceleration, for example tempur. These materials now have civilian applicatons). The detonator at thorpe park goes to -5.5g. Wikipedia says the highest g force sustained by humans were (voluntary 46.2g astronaut john stapp, involuntary 180g F1 driver David Purley in an accident). But surviving high g's for a short time and for a long time are different things. We'll take a n aggressive estimate and say we could accelerate at 5g's sustainably. To reach .001c with 50g's would take .003e8 m/s / (5 * 9.8m/s^2) ) ~= 8 hours (neglecting relativistic effects, real time would be longer... lets say we can increase the force arbitrarily to compensate for relativity, again more new physics needed). So we need 16 hours to reach that speed, and another 16 hours to decelerate at the other side, means 16 hours accelerating and decelerating, and I'm neglecting more relativity here, but again on the aggressive side.
My next point is often neglected. What happens if you hit a little meteorite (It could be the size of a pebble, or even just a little cloud of dust). If that smacks into you at .001c relative velocity, you can bet it's going to do a lot of damage, even without considering relativistic mass. Think about how much damage small meteors do impacting earth at terminal velocity, which is probably at .00001 c or something... So we need shielding technology. Think about how much trouble the shuttle has with it's shielding tiles...

Combine that with 2 launch systems, one for earth and one for the moon. By 2010, there will be at least 5 human rated systems (Russian, China, Space Shuttle (probably will not be fully canceled until we have orion going) or Orion, and the 2 cots system). By 2014, the Sundancer will have been in orbit for at least 3 years. That will make it acceptable for taking to the moon and landing on its surface. All that is needed is a landing system for it, a connection module, and a true lunar transport. Finally, the BA-330 will be available by 2015 (I would guess by 2011) and that will be used for the real transport to lunar orbit.
