thats why i strongly believe in private space explorers, nasa is the governments baby who is solely dependent on them for money.....maybe if we can get a good private corp. to do it then its possible we can go (back) to the moon?
Space exploration by the US (and by every western country) has
always been a joint effort of government and industry. And I think it will be for the forseeable future.
We establish governments, among other reasons, to do or at least fund the things that we all agree are important but don't have the inherent profit motive that motivates private corporations. Basic scientific research (with no obvious short-term payoff) and space exploration are among those things. Despite a lot of hype in recent years about space tourism, aside from communications and possibly earth imagery there simply hasn't been a viable commercial market in space travel. And unless there is a revolutionary breakthrough in propulsion, I don't expect this to change.
So why doesn't the government do it all? Because western private industry has often proven much more capable than formal governmental bodies at efficiently managing large numbers of people in highly complex projects. But don't forget for one moment that most of the western space industry exists to serve one class of customer -- government -- for both military and scientific purposes.
So the government provides the funding for space exploration and industry provides the goods. And it will be this way for the forseeable future. The only real question is where exactly to draw the line between those functions performed by the government (i.e., NASA) and by their private contractors. Although most of Apollo was done by the contractors, a substantial amount was done within NASA. Many people questioned this, and still do.
So SpaceX represents one of several contemporary experiments in moving the line to put much more of the work on the contractor side. The idea is that the government should say only that they'll pay Y dollars if and only if a particular service or goal is performed, e.g., delivering X tonnes of cargo to the ISS. Instead of micro-managing all the design details, they only specify what has to be done (and some safety rules) and leave all the details of how to perform it to the private companies.
I had doubts about this approach at first, but SpaceX is starting to change my mind. Maybe this approach isn't such a bad way to do space exploration after all. But don't think for a moment that companies like SpaceX would do it out of the goodness of their hearts if the government weren't paying.
