Space travel is still dangerous, even when not in space:

Thankfully, this was a test vehicle, not the model currently being used to launch payloads into earth orbit.

It looks like it will be Boeing and SpaceX who will get American astronauts into space on American spacecraft.

Interesting choice. The traditional company Boeing got a huge chunk of the cash. SpaceX got about half of what Boeing got. But, Mr Musk claims he can do it cheaper.
The Dream Chaser looked interesting, but they have not managed to impress the NASA folks for some reason.

Always good to have two sources or else you could end up without a ride (like we have now). Who knows, maybe the Boeing cost number is more accurate.

Never mind.
BBC News - Protest halts Nasa spaceflight plans
TL ; DR - Sierra Nevada Corp protested the contract award. The commercial crew program is on hold at least until the GAO issues a ruling in January 2015.
Nothing to see here. Move along. Move along...

The mini-shuttle design is interesting and aesthetically pleasing, but I am not sure what advantage it offers over the SpaceX craft.

I did find it interesting that India's mars mission at $75 million was about 1/5 the cost of the fairly similar NASA mission, or as the news headlines said less than the cost of the movie Gravity.
I got to believe the NASA bureaucracy, like this example has got to be a big reason for the cost.

You may be right. That would make the choice of SpaceX's even more significant since Mr. Musk is not known for tolerating expensive nonsense.

The way the two agencies calculate cost of a mission are very different. NASA includes facilities, development, and operational costs that ISRO does not.

In addition to how the cost is calculated, the capabilities of the two missions is very different.

It looks like NASA has decided that delaying the commercial crew project might be hazardous to the health of astronauts and the ISS. Sierra Nevada corp will have to fight it out with the GAO while Boeing and SpaceX march forward.

If SpaceX can pull this off, it will be quite an achievement. I see that NASA is looking at their techniques since something similar will be needed to land big objects on Mars.

Just a few days ago read that the fuel cost of a rocket is only about 200k, a tiny fraction of the total cost.
Didn't realize it was that big of a deal to reuse the launcher. Now I understand Musks obsession with land & reuse.
Hope he keeps on making strides.

I believe the big part of reusing the first stage was being able to restart the rocket engines while the vehicle is falling backward into Earth's atmosphere at hypersonic speeds - Mach 5 or above.
