Better, Faster, Cheaper, Discuss..... Options

[lyford]

Can one paraphrase the quip about the "Holy Roman Empire" being neither holy, Roman nor an empire regarding this plan?

The idea, if I understood correctly, was this: By designing cheaper missions, NASA could launch more, and afford to lose a few more. The BIG MISSIONS were too expensive and put all the eggs in one basket. Why take a chance on any single failure points that could risk a program after bagillions of dollars were spent, such as Galileo's hi gain antenna?

Was this strategy successful?

To this outsider, it appeared that Dan Goldin drank too much of the 90's cyber-revolution kool aid and got swept up with the "irrational exuberance" of the dot.com boom. Everything will be possible and cheap in the digital age! Moore's Law notwithstanding, hi tech is only one piece of the puzzle when pulling off a successful interplanetary mission.

My opinion is that there is a baseline cost of doing business in space, even if sensors get smaller and cheaper, due to human support, testing, launch costs, etc. Even the "tech" components all have to be space rated, which is not the kind of consumer level mass production ultra cheap type tech with which most people are familiar. (I have had more than one conversation about why JPL couldn't have had bolted a cheap color digital camera on MER.....)

While adopting this plan may have allowed some missions that might not have seen the light of day before, each little failure seemed to hit NASA with more bad PR than the little successes could offset....

SO -

"Better Faster Cheaper : Golden Egg or Goldin's Goose?"

I would value all opinions, especially from those inside the org, natch.

I imagine that $111 million figure is for the cost of flying Shenzhou VI only. It's not the cost of the entire Shenzhou program.

About how much did it cost to fly a single Gemini mission (to which the Chinese flight is comparable)? In today's dollars, of course. I bet the costs are similar...

As a comparison, it cost about a quarter of a billion dollars, in 1969 dollars, to fly a single Apollo lunar landing mission. Those were a lot more complex, and used more resources, than a simple two-guys-in-orbit-for-four-days kind of flight, of course.

The cost of the entire chinese manned spaceflight program is $2.3 billion.
