You like weather forecasts, right? Weather satellites freed fleets of aircraft and ground stations from creating a patchwork image of cloud cover.
You like eating, right? We have satellites measuring the health of forests AND FARMS, which help us estimate crop yields and can set the market costs even before meat, fruit and vegetables reach the processors.
You like television, right? Television programs use to be relayed across the country and compressed so much that the east coast thought Hollywood could only do film and the west coast knew the easterners for the worthless, blurred colorless taped programs. Direct TV wouldn't exist without NASA.
You like telephones, right? Can you imagine the effort it took for a secretary to place a long distance call? Ma Bell took its sweet time innovating, didn't she?
I wouldn't call the space program "worthless" by any truthful measure!
