NA's experience & education centered around aeronautical engineering & flying. He isn't a phycisist, such as Albert Einstein or Stephen Hawking. That being said, however, he has made some very eloquent comments on early lunar observations the suns angle, the optical properties on the moon, & the geological findings based on the rocks that were brought back. He has immersed himself in such subjects more out of enthusiastic interest, I would imagine, as opposed to being a recognized authority in the subject.
They both contribute to the knowledge of space exploration, because they bring so much happiness and evidence from the moon that Americans and other people got interested in this.

It shows that we do not fully understand the formation of our Solar System.
He found out that the sunn is the center of solar system
Geocentric understanding places the Earth at the center of the solar system or universe (depending on what is being discussed, and when) A Heliocentric understanding places the sun at the center of the solar system, or universe.
Kepler used Tycho Brahe's data to establish the heliocentric theory of the solar system.

The mission of the ISS was to understand how mankind could live in space, not necessarily to further understand the solar system.
He provedthat planets moved in elliptical orbits.

I don't think Nasa's understanding of the Solar System would, in principle, be much different from the understanding of the Solar System you can get from good astronomy books, or television programs. Except that people who work there would probably be informed about some more details - and know more about the math and physics - than you would normally find on popular television programs.

Albert Enstien comtributes to our knolage of the solar system by helping us understand space travel and advanced forms of gravity.
Ptolemy contributed to science and astronomy by developing the theory of the Earth. He was the first person to view the solar system as a heliocentric system instead of a geocentric system.
In general it was thought to be a sort of mini-solar system.
