Mariner?

In 1976, after a year's voyage, two robot explorers from Earth landed on this alien shore. On Mars, there is a volcano as wide as Arizona and almost three times the height of Mount Everest. We've named it Mount Olympus. This is a world of wonders. Mars is a planet with ancient river valleys and violent sandstorms driven by winds that half the speed of sound. There is a giant rift in its surface 5,000 kilometers long. It's called Vallis Marinaris, the valley of the Mariner spacecraft that came to explore Mars from a nearby world.

1976年，兩臺(tái)從地球發(fā)出的機(jī)器人探測(cè)器在歷經(jīng)一年的飛行之后，在這片陌生的海岸登陸?；鹦巧嫌幸蛔鹕?，它有美國(guó)亞利桑那州之寬，幾乎是珠穆朗瑪峰三倍之高，人類曾將它命名為奧林匹斯山。這是一片充滿了奇跡的土地。火星上遍布古老的河流峽谷，猛烈的沙塵暴在風(fēng)力的作用下速度竟能達(dá)到一半光速之快。火星表面上還有一道長(zhǎng)達(dá)5,000千米的巨大裂縫，稱為水手號(hào)峽谷，也就是從周邊星球發(fā)射來(lái)的水手號(hào)宇宙飛船探測(cè)火星所抵達(dá)的地方。
