如果你能飞越火星，你会看到什么？这张特色图片正是以火星快车7月份在火星上一个特别有趣的地区拍摄的远景图的形式展示了这一点。这张照片最著名的特征是奥林匹斯山，太阳系最大的火山，在右上方可见。在右边的地平线上可以看到另一座大的火星火山：帕沃尼斯火山。在这颗红色行星的表面可以看到几个圆形的撞击坑。令人印象深刻的是，这张照片的拍摄时间正好捕捉到了黑暗和注定要灭亡的火星卫星火卫一，就在中间偏左。左下角的地表特征，被称为奥库斯帕特拉，它的大尺寸和椭圆形是不寻常的，神秘的是它的形成过程仍然未知。2003年，欧洲航天局发射了自动火星快车号宇宙飞船，在许多重大科学发现中，它支持了火星曾经有大量水体的证据。

If you could fly over Mars, what might you see? The featured image shows exactly this in the form of a Mars Express vista captured over a particularly interesting region on Mars in July. The picture's most famous feature is Olympus Mons, the largest volcano in the Solar System, visible on the upper right. Another large Martian volcano is visible on the right horizon: Pavonis Mons. Several circular impact craters can be seen on the surface of the aptly named red planet. Impressively, this image was timed to capture the dark and doomed Martian moon Phobos, visible just left of center. The surface feature on the lower left, known as Orcus Patera, is unusual for its large size and oblong shape, and mysterious because the processes that created it still remain unknown. ESA's robotic Mars Express spacecraft was launched in 2003 and, among many notable science discoveries, bolstered evidence that Mars was once home to large bodies of water.
