Mars is the planet which I like best. It's the first planet I had observed.
I like planets very much. They're always so twinkle even in a cloudy night. I always think them as earth's relatives - Venus, the sister; Mars, the brother - and the Moon as wife.
I was always interested in Mars' atmosphere. But one day, when I explore marscany, I feel so great it can be.Think it over, if no asteriods hit planets, there wouldn't be life on earth. We wouldn't exist here.
So I want to understand how the asteriods hit by planets (or moon).How the atmosphere prevent the damage etc. So I want to find an atlas of Mars to see how craters on it can be. Unfortunately, it's very hard to find such a info. Finally, a post on Newsgroup told me to link to NASA's Mars Page.
I got data I needed.(actually they are not enough for me) So I get some statistic about craters on Mars. And I'll think of other factors in the future.
Mail me if there's any suggestions, and I'll also be glad to discuss with you. ^_^
