I quickly scanned a couple of books at the nearest library, and the
following numbers caught my eye:  

The total budget for Columbus first voyage was 1,900,000 maravedis
(mv).  The Spanish Court contributed 1,400,000 mv, and Columbus himself
pitched in 500,000 mv, which he borrowed from a private banker. [1,2] 

In 1492 a maravedi was worth 0.0096 grams of gold [1].  We could figure out
the dollar equivalent from this, but the result would be misleading, since
the purchasing power of gold itself (compared to the cost of living)
dropped a lot (fifty-fold?) in the last five centuries [2].  

A better estimate can perhaps be obtained from the following data.
Total wages for the 90 officers and seamen who accompanied Columbus were
about 250,000 mv a month.  Ship capitains were paid 2500 mv a month; seamen
got 1000 mv, and ship boys 666 mv.  These were standard goverment-regulated
wages for long-duration exploratory voyages [1].  A bushel of wheat cost 73
mv; 360 mv bought enough provisions to feed a sailor for one month [3].  

It is reported that when Queen Isabella was convinced by one of her religious
advisers that Columbus (who was out of town at the time) was worth
listening to, she sent him a summons, and a gift of 20,000 mv ``to
buy a horse and appropriate clothes'' for the trip back to the capital [1]. 

The population of Spain (Castilla+Aragon) at the time is estimated as some
9,600,000 people [4, p.13].  Laborer wages were around 450--600 mv per
month [4, p.106].  Columbus first voyage cost then 0.20 mv per capita, or
1/2200 of a worker's monthly paycheck.  The people directly working for the
`program' were less than one 1/100,000 of the total population.  

How do these numbers compare to the Shuttle?  If we take $1 billion as the
average yearly cost of the Shuttle program so far, we get $4 per capita, or
1/750 of a `laborer's' $3000 monthly paycheck. If I am not mistaken, the
Shuttle program was using up more than 20,000 full-time jobs; that is
more than one American in 13,000.

(No, I have no references for those numbers.  They are the best I could
make up at the end of a rather long day.  Please do provide your own.) 

At the other end of the spectrum, annual income (from land rent only?) of the
topmost 82 households in the Spanish nobility, excluding the royal family
itself, was about 550,000,000 mv a year, or 6,700,000 mv a year per
household on the average [4, p.101]. That is about three times Columbus'
first trip budget.

Just for curiosity, the total amount of gold and silver (owned by the
Crown and by private citizens) that arrived in Spain from the Americas
between 1503 and 1660, according to customs' records, was about
250,000,000,000 mv, or about 1,600,000,000 mv a year on the average.

Is that grounds for disqualifying my evidence? :-)
