About as wrong as you can get.
the space program has yielded scientific breakthroughs which could never have been achieved otherwise.
Utter NASA Koolaid. BE SPECIFIC, List a dozen - other than the ability to build large rocket engines and the technology to handle cryogenic fluids. IF THEY'RE SO MANY YOU SHOLD HAVE NO PROBLEM Remember you set an impossible bar when you said "which could never have been achieved otherwise" Oh and do us both a favor and check the origins of the so-called space program discoveries at some site OTHER than NASA. There is a NASA site that shamelessly claims the originations of such things as velcro, transistors, etc.
There is zero evidence that space program has NOT advanced science and technology. You can argue about origins of various breakthrough discoveries.
Like I said, we spend more by ORDERS OF MAGNITUDE on food stamps, unemployment checks for 99 weeks (at the end of that period majority miraculously finds a job), and benefits to illegal immigrants, than we spend on space program.
You really need to get your sense of proportion in order.
