you seem to not know much about orbital insertion
Ha! Are you kidding me?
I was a history major, never studied rocket science, closest I came was astronomy and didn't do so well there -- too much math, not enough star-gazing! ;-)
But I well remember when the US launched men to the moon on Saturn rockets from Cape Canaveral, Florida.
So, the Cape was good enough then, but not today?
Today we have to risk "pirates" stealing our stuff to launch from French Guiana?
So, Mr. Scientist, let me ask the question this way: exactly how many gallons of rocket fuel do we save launching from French Guiana instead of Cape Canaveral?
And what is the price per gallon of rocket fuel these days?
So, let me guess the answers: it'll save 50,000 gallons of rocket fuel launching from French Guiana and rocket fuel costs $10 per gallon = a $500,000 savings and for that we're going to risk our $10 billion state-or-the-art telescope getting robbed by "pirates"?
You're kidding me, right?
