    Unnecessary wars cost trillions of dollars.
    Spacecraft mission costs are more like a billion dollars.

NEW YORK (Reuters) - <<The U.S. war in Iraq has cost $1.7 trillion with an additional $490 billion in benefits owed to war veterans, expenses that could grow to more than $6 trillion over the next four decades counting interest, a study released on Thursday said. >>

<<The total cost of the Voyager mission from May 1972 through the Neptune encounter (including launch vehicles, radioactive power source (RTGs), and DSN tracking support) is 865 million dollars. At first, this may sound very expensive, but the fantastic returns are a bargain when we place the costs in the proper perspective. It is important to realize that:

    on a per-capita basis, this is only 8 cents per U.S. resident per year, or roughly half the cost of one candy bar each year since project inception. the entire cost of Voyager is a fraction of the daily interest on the U.S. national debt.

    A total of 11,000 workyears was devoted to the Voyager project through the Neptune encounter. This is equivalent to one-third the amount of effort estimated to complete the great pyramid at Giza to King Cheops.
A total of five trillion bits of scientific data had been returned to Earth by both Voyager spacecraft at the completion of the Neptune encounter. This represents enough bits to fill more than seven thousand music CDs.

The sensitivity of our deep-space tracking antennas located around the world is truly amazing. The antennas must capture Voyager information from a signal so weak that the power striking the antenna is only 10-16 watts. A modern-day electronic digital watch operates at a power level 20 billion times greater than this feeble level.>>

Suppose we eliminate the purchase of weapons
Suppose we eliminate all the world´s army
Suppose we eliminate all kinds of wars
That would give an enormons quantity of
resources to invest in food and medicines
for millions of human beings. Indeed!

Beautiful thoughts saturno2.

I wonder if declareself’s incomplete comment was really a complaint about these missions’ costs. If so, it was over stated by a thousandfold or so, but he didn’t say “cost”, he said “caused”. Perhaps this is what he meant:

“These missions caused us trillions of dollars” of benefits in knowledge gained.
