Curious how often this rocket can be re-used and how much it costs to prepare it for the next launch. | ||

the only 1986 shuttle flight blew into a million pieces. i don't think it got "re used" is the Falcon9 better than the 1981 Space Shuttle? the devil is in the details. if the Falcon9 costs as much as the shuttle did to make a return flight then Musk's accomplishment means very little. If ,on the other extreme, SpaceX can put the Falcon9 back up into space a few days later with as much maintenance as a 747 requires THEN this is a major accomplishment. the actual technical feat does not mean a lot. what means a lot is the maintenance costs of re-usability. Another technical milestone that is not completed is putting actual cargo into space the way the Shuttle did. | ||

At one point in the SpaceX webcast of the launch the moderator had to remind viewers looking at SpaceX employees whooping and hugging after the landing that the mission’s main objective, after all, was to deploy the Orbcomm fleet. But it is the second stage’s performance that will position SpaceX to conduct commercial operations the way it has long intended. SpaceX said the second stage engine performed the full re-ignition and burn sequence needed for geostationary satellites. Source | ||

there was lots of engineers celebrating during the Shuttle and Apollo Era.. and where are we after all that? | ||

also the space shuttle had some parts that were NOT fully reuseable (the big orange tank burned up) and some parts that had to be rescued to be reused (the solid boosters fell into the ocean and required considerable effort to be functional again) etc. Much higher cost. And in truth, we aren't comparing the same things. The shuttle wasn't a reuseable launch system, it was a reuseable orbiter. Most of the launch system was not reuseable or at least difficult and expensive to reuse. Falcon 9 is completely different in that it's an entirely reuseable launch system. What it launches is somewhat irrelevant (although the payload does have fairly specific parameters). | ||

any way you slice it its all about lowering costs. if it costs me $50,000 to rebuild a completely new entity that can stick heavy cargo into space then we have a winner. it does not matter how good or how bad it looks in a video, it does not matter how much of the thing gets re-used. its all about a low cost solution. | ||

and also raw # of re-uses is another factor. how "re usable" was the shuttle?. 1 shuttle got what? 30 flights maximum. and didn't 2 out of 6 fail. if 50% of the Falcon9's fail to land properly are they "re usable"? if a Falcon9 can take off and land as reliably as a 747 we have a winner. if its just another 30 max re-use product that fails regularly then i'll borrow a famous american saying " its deja vu all over again " | ||

You literally repeated yourself twice on this page of the thread alone. We get it, you are not impressed. | ||

Comparing what SpaceX accomplished live for the world to see to BO's secret project is simple ignorance. The technical feat is orders of magnitude apart. You should also be happy if Nasa spends less money in their projects and funnel it to private companies (Spx, ULA, BO, SNC, BA) because they are clearly capable of spending that money better. All the money they got in the last 30 years didn't accomplish anything as ground breaking for spaceflight as Musk's little fortune did. Unless you're happy with SLS costs for what it actually does. Or maybe you think that money is better spent on the DoD. | ||
