Is it just me or is NASA just burning $? Did they learn enough from this little experiment to justify the cost?

I personally think their budget should be doubled or tripled. We’re talking about the exploration of humanity. Just look where we were 200 years ago. We were using horse and carriage and a mere 200 years later we have self driving cars and have landed on the moon. I’d say with in the next 100 years or so we’ll be a space faring people and America needs to be on the cutting edge of the technology involved. Exploration costs money, I’d much rather us use it at home instead of sending billions upon billions abroad to other countries.
