There are neither spinoffs, nor do the actual projects represent valid research with the exception of the space telescopes. Did you know that we gave the 35 billion dollar space station to the Russians? Any idea why?
Practically speaking, we will never inhabit space and we get no usefull science from manned space travel. But the government loves to tell scifi stories to justify enourmous expense which is simply pork barrel politics.
We already do, so get a clue, ok?
Or is that space station up there with people in it doing scientific experiments just a figment of my imagination?
Gad! What planet are you from?
Oh heavens, where to start? Ever use a computer? Drink Tang? Fruit juice from a pouch? Talk on a cellphone or a regular one? Ever wonder why we won the Cold War? Use medication? Eat food from a grocery store? Watch a weather forecast? Have a dish on your roof?
I could go on and on... However, considering your statements, it would just be a waste of time as I am sure you fully believe them. Just how you do is beyond me...
You need to look up from the book and see the world around you.
