The problem for all of the explanations of the origin of life from inanimate matter is that none of them holds up to even cursory scrutiny. The one thing that seems most likely is that the innate probability is very small, and given 1,000,000 planets in the universe with a climate that could theoretically support life, it is possible that only an extremely rare and fortuitous con¯ux of events led to the formation of life on one planet (or possibly a few). If life evolved on only one planet, we are the oneÐwhich we recognize by Descartes' logic.

Alternative pathways for carrying out a campaign can be represented by a ``treediagram'' showing campaigns as paths through arrangements of sequentially arranged missions. , best sequence of missions) according to some ®gure of merit for the campaign. However, this is a complex subject and is beyond the scope of this discussion. 2 PLANNING SPACE MISSIONS In planning a space mission, the ®rst thing to consider is why do we want to do it, and what do we hope to derive from the results? The next questions deal with the feasibility of the enterprise as expressed by the following questions: .

Each mission involves at least two possible outcomes with probabilities assigned. After Mission 1, do Mission 2A if Event A happens, or Mission 2B if Event B occurs. There are a number of possible outcomes for each campaign (each with a di€erent series of missions, and di€ering cost, risk, and performance). Alternative pathways for carrying out a campaign can be represented by a ``treediagram'' showing campaigns as paths through arrangements of sequentially arranged missions. , best sequence of missions) according to some ®gure of merit for the campaign.
