What are the major things that have happened in space travel to date?

I've been wondering this for awhile...

You have obviously given this deep thought. I am surprised that you managed to come up with so much original material. Such bold direction - not a scrap of what you think is wrong. What it must be like to have a brain uncluttered by things such as thoughts and ideas.

What about
- first rocketry theory
- Peneemunde/werner von braun
- Sputnik
- early US attempts
- research how close the Russans came to landing a man on the moon first
- Appollo program
- July 1969
- Space shuttle
- various American and Russian space stations
- exploration using robotic craft (remember to include Voyagers and Pathfinders, although do not exactly fit this profile)
- the current problems which stop us sending a person or crew to Mars

If you use these as chapter headings and write a page on each, you would expect a reasonable score - assuming your reseach was in fact correct.
