Space technology benefits are just so numerous that it would be hard to list them all. The joke used to be that only TANG, the powdered orange drink, came out of all that money spent. FALSE! And remember that some of these benefits would have come later anyway, many years later, because of the ay Science and innovation logically builds on knowledge and products that already exist. But the space program accelerated developments in many areas because problems had to be solved to get astronauts to the moon and back alive, and they did it in less than 10 years. The benefits follow;
Rocketry had to be improved to get bigger and heavier payloads (capsules, equipment, supplies and people) up into space, to accurately guide the rockets and space stations, to make repairs in space, and to do with unheard of reliability.
Miniaturization in electronic, computer, medical, and other equipment was advanced to take up little physical space, operate on low power and under unusual weightless conditions for extended periods of time. This led to our system of communication and TV satellites that give you DirectTV, cell phones, GPS locational services on your computer and cell phones, etc.
These needs to miniaturize and make more reliable products speeded up the digital revolution, micochip design and manufacturing, quality testing, etc., that have improved the production and quality of ordinary complex products like cars, airplanes, and even much simpler products.
The Hubble telescope assembled in space above our atmosphere has and continues to provide new data about the Cosmos that is changing our understanding of the cosmological physics involved.
It expanded robotic technologies into manufacturing, medical fields, simpler detection of problems, handling of hazardous environments, etc.
It expanded our knowledge of the nature and requirements for an ecosystem in space or on other planets.
And on and on. So the money was well spent since the benefits keep on giving year after year, and our technologies expand even further and sooner.
