耐心等待看完
令人興奮的時刻
太壯觀了 真是大開眼界
More good news from Mars for the last several yesrs: It has atmosphere and weather, it has terrain which Jupiter and Saturn do not have (they are made up of gas only). The soil sample taken in 2008 confirmed the presence of water on Mars and NASA also confirmed the presence of methane in 2009.
