Reusability is a key to any plan to making human life interplanetary, according to the CEO of SpaceX, one of the companies tasked with ferrying cargo, and someday astronauts, to the International Space Station.

Reusable is vital for sure.

Yep, Elon Musk -- Two great companies! SpaceX and Tesla Motors!

I want one of the Tesla cars so badly!

Did you also know that he was co-founder of X.com which merged with Confinity which also operated a subsidiary called PayPal? Much more here.

The Soyuz TMA and Space Shuttle is/was reusable.

Nothing that has ever left low earth orbit has been reusable.

It seems to me to be a waste of resources to ferry something more than a half a million miles (to the moon and back) just to have some parts left over.

The Saturn V F1 (first stage) and J2 (second stage) engines were abandoned but could possibly have been recovered, as Apollo 11's recently were.  NASA apparently thought it wasn't worth the trouble to make them reusable and recoverable.

just guessing, but nasa probably knew (at the time) that there was no future in space.

although by the time you click this nasa link, no telling what will be on the page http://www.nasa.gov/...ructure/launch/
because it looks rather generic.

but the spacex / dragon resupply vessel is slated to fly april 14 or 18. - the dragon is cool, but one day spacex hopes to lob humans into the space station.

SpaceX is doing amazing stuff, but it is important to note that any tech they develop in their program will not be the property of the American people, unlike NASA's work over the years.

The company is for-profit, so they see a future in figuring out a way to lower costs, but it will not be a benefit to society at large.

That's the difference between publicly funded and privately funded. It should be that way to a very large degree. Although some industries take it to extremes.

Tweak it 'til it breaks, then learn how to fix it.

true, publicly funded with its massive cost over-runs vs a private company that must be lean to be competitive. but i guess the legendary $1000 toilet seat for the c-130 kept lots of folks employed back in the 80's. and indeed almost all modern telemetry that hospitals enjoy came directly from nasa, as is much else of good in our society.

Well, you certainly aren't going to go from barely launching into orbit to landing on the moon without spending a lot of money, with overruns.

I am thinking back to watching the mini-series "From the Earth to the Moon." They detail only some of the engineering challenges they went through in order to get the anstronauts back safely. It's almost miraculous.

Want to have fun? Come over to my house. You stand in the back yard, I'll stand in the front, you throw a tennis ball over my roof and I'll try to hit it with a rock as it comes sailing over. That's what we're going to have to do...

Credit where credit is due.  That's Chris Kraft in the first episode of From the Earth to the Moon.

Indeed it was. I'm amazed we managed to do it back then.

yes, & i think that is why there are sooooo many conspiracy theorists who say it was not possible.
as i've said, my dad was a missile & manned space test engineer, and i never heard him make a disparaging remark about the moon program.
(however, when he was involved with the space shuttle in 1975, he said, gee, that thing is old!)

Yeah, I think my wristwatch was more powerful than the space shuttle computers......

Internet Help Desk (not the mp3 version I have but it's close) ... where they talk about the guy having a computer 10,000 times more powerful than what we used to send a man to the moon....

On my version it says I've been here for 8 months ... that's like 25 years in Internet time. ;)
