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，两台从地球发出的机器人探测器在历经一年的飞行之后，在这片陌生的海岸登陆。火星上有一座火山，它有美国亚利桑那州之宽，几乎是珠穆朗玛峰三倍之高，人类曾将它命名为奥林匹斯山。这是一片充满了奇迹的土地。火星上遍布古老的河流峡谷，猛烈的沙尘暴在风力的作用下速度竟能达到一半光速之快。火星表面上还有一道长达5,000千米的巨大裂缝，称为水手号峡谷，也就是从周边星球发射来的水手号宇宙飞船探测火星所抵达的地方。
