There is also a book called _Planets_for_Man_ written by Dole and Issac Asimov, a few years later. The collaboration, not surprisingly, is much more readable, and where Dole's work alone is a very sketchy work, Asimov & Dole's collaboration expands on Dole's study, including a great deal of biological and biochemical aspects of habitability not covered by Dole alone. -- Clayton E.

Fixed-price means that NASA will pay a certain, fixed, price for an item. The price is established and can't be changed, even if the contractor is going to loose its shirt. On the other hand, if the contractor can make a huge profit (by discovering a new process, for example) that's OK. Then there's cost-plus-fixed-fee, where the contractor makes a fixed fee over a variable cost of production. This reduces both the risk and the size of reward. Fixed-price is common for routine items, cost-plus-fixed-fee is more common for new or experimental items.

Surely a fixed price contract means that for every $1.00 saved from the firm, fixed price, Rockwell would be able to keep 100 cents?

With all the talk of going to the moon and and setting up a base it seems like this would be best performed by sending up a booster that the shuttle could ride to the moon. With its cargo bay, it has the best capability of releasing and transporting modules. It may seem simple question to some but I see no reason why it can't be done. If you could enlighten me, I would greatly appreciate it.
