甘博阿陨击坑，火星

在火星上生存相当艰难，天气极寒、干燥，而且条件恶劣。火星上的平均温度约为零下62摄氏度，两极的温度甚至可能低至零下152摄氏度。但这颗行星上有许多峡谷、死火山和冰盖，远观还是很美的。火星勘测轨道飞行器发回的大多数照片都显示火星是一颗红色星球，这是因为火星表面有大量红色的赤铁矿，所以呈现橘红色。

这张照片展示的是甘博阿陨击坑，但这并非甘博阿陨击坑的真实颜色。科学家们对这张照片进行了校色，视觉效果更直观，更便于科学分析。

Gamboa Crater, Mars

It would be pretty tough to live on Mars. It's cold, dry, and the conditions are harsh. The planet's average temperature is about –81 degrees Fahrenheit, but it can get as low as –243 at the poles. But with many canyons, extinct volcanoes, and ice caps, it's beautiful to look at from afar. Most photos of the Red Planet highlight its rusty color, caused by high levels of iron oxide.

This photo shows us Mars' Gamboa Crater, but not with accurate colors. Scientists have recolored the wavelengths that our eyes can't see on their own. These added details let us see the effects of wind inside the crater, providing a perfect example of the spectacularly complex features of this planet.
