Here is the deal - it only has to be taken down now, their goal is to get to a point when they wouldn't need to refurbish it outside of launch pad - land, refuel, replace few consumable parts and relaunch from the pad.

By September 2011 SpaceX announced their shift to powered-descent first-stage recovery ( link to 2011 space.com article). Presumably they found additional funding and/or ways to reduce development cost. But this still seems like science fiction.

I realize the goal of landing this is to re-use it. But how much burn and usage damage must be repaired to ready it for another launch? Any idea what the landed section would cost if destroyed? Since they say cost of relaunch is 50% and you need to refuel I'd say the stage 1 hardware costs about 75% of launch cost, 25% for fuel, some TLC and some profit on relaunch and you are right at 50%.
The fuel cost is almost irrelevant, about $200k.

Space X has some competition. They're in the beginning stage... The landing at the 2:40 mark is a bit rough. [youtube]http://youtu.be/xaWWZEDjMW0[/youtube]

I once accidentally set off about two dozen of those Estes motors out in my shop. I was cutting metal, and didn't realize where my spark shower was being thrown. Scared the crap out of me when the first one lit off.

SpaceX is all about getting things done, no excuses, fail and get back up and succeed. Also, the workers at SpaceX are very young and motivated. They don't sit back and wonder what retirement will be like or how to plan their next "sick" day, instead, they are working hard at the upcoming mission and how to make it succeed. Will Elon land on Mars in 2024 as planned? Who wants to bet against him?

Failures are how we learn and advance.

The question posed on CNBC this morning is "what's the ROI"?. I agree, what do you get out of going to Mars? There's nothing there.

Culumbus didn't personally get squat from putting the americas on the map. But centuries later school kids still learn his name.

Reminds me of a motivational consultant. Taking the stigma out of failure. Fail faster was the recommendation. Don't be afraid to push the envelope. If a plan doesn't work, learn and move forward. For the to work you need to have buy in from the top. Not every businesses have someone like Elon at the top.
