In regards to Branson, I'm not really certain what his expectation is other than fueling space tourism. Considering how long I've been hearing about Virgin Galactic, this is the first time anything has come of it.
On the flipside, what Musk has done, and is still working towards is truly amazing. Even if a human going to Mars is a suicide mission right now... well, so were some of the first Europeans coming across and settling in America.
The Lady could care less about Astronomy, Space travel, etc... and I agree that there is a strong element of why money gets spent there when we can't even take care of sh!t on the ground. But at the same time, Space technologies also have greatly improved some aspects of life on the ground, and perhaps could be a necessity for the future of Earth and/or humans.
Maybe that's a good thing, maybe not... guess it depends on whom you ask and what day you ask it!
Either way, what is exciting about what Branson did is that this is a civilian venture: not government, not military.
Just like the first Falcon to deliver a satellite to orbit, and the first time they stuck a booster landing, too. For SpaceX, the focus is on advancing our capabilities to get to space and do it for much less money.
I am curious to see what comes of the Bezos' effort with Blue Origin as it seems they are following more in the footseps of Musk/SpaceX.
