Thoughts on the GWB Return to the Moon...Posted By K. Michael Malolepszy |
Kind of suprised at the lack of support on this web site for human spaceflight. I for one think we need to keep flying humans for a couple of reasons in the long run:
1) One day we will get whacked by an asteroid large enough to destroy more than just a city. Everyone here knows that it's just a matter of time. Perhaps a long time, but it is inevitable. Humans could do something about that - IF we have a substantial technological and experiential human spaceflight base. Let's say we shut down human spaceflight and 100 years from now, humans find the kilometer sized asteroid that is going to impact us. Will our descendants be able to resurrect human spaceflight capability in time to do something about it? Or will they be wishing they still had a generation of space cadets around?
2) I'm one of those silly people that thinks in the long run we may need to tap ET resources. maybe I read too much Gerard O’Neil;

Plenty of stuff to mine on near earth asteroids. Even the moon is good for some materials. It has been argued that breeder nuclear reactors could supply all of our energy needs in the foreseable future. I don't like the idea of putting all of our energy eggs in one basket - that's why the mess that is the middle east so damned important to us now. Even if nuclear fusion becomes a viable energy source (for how long have we hearing that it's coming..?) dueterium mining of the moon might be feasible as an fusion energy source. If nothing else, the moon and NEAs will be resources for a non-earth based population. I hope that in 1,000 years we will have as many people (if not more) off the earth than on it.
Save earth - put the Big Machines in space where they belong
In the short run, I think that Human Spaceflight is one of those really noble technological endeavours that may pay for itself and inspires kids (and adults!) to study science and mathematics, and we'll need all of the talent we can muster if we are going to compete with India and China.
