Space Travel is Cheap (Score 1)

Going to Mars is cheap. Giving lunch money to countries like N. Korea and Iraq so they can instead use it to build a military that will eventually be used to try and destroy us is expensive. Giving billions to failing countries like Argentina to keep them afloat so we don't have an even bigger mess to clean up later is expensive. Letting our own citizens defraud every government aid program (welfare, medicare, medicaid, etc...) is expensive.
We may actually gain some valuable return from a visit to Mars. That is something we don't get from barely anything out we spend money on now. Except for maybe National Defense, but most people want to cut that anyway.
