好奇号庆祝在火星上的又一年

On Aug. 5, 2012, NASA’s Curiosity Mars rover landed safely on the Red Planet.

In this self-portrait from 2018, Curiosity sits atop Vera Rubin Ridge, which the rover had been investigating. Directly behind the rover is the start of a clay-rich slope scientists are eager to begin exploring. In the coming week, Curiosity will begin to climb this slope. North is on the left and west is on the right, with Gale Crater’s rim on the horizon of both edges.

Poking up just behind Curiosity’s mast is Mount Sharp, photobombing the robot’s selfie. Curiosity landed on Mars five years ago with the intention of studying lower Mount Sharp, where it will remain for all of its time on Mars. The mountain’s base provides access to layers formed over millions of years. These layers formed in the presence of water—likely due to a lake or lakes that sat at the bottom of the mountain, which sits inside Gale Crater.

This mosaic was assembled from dozens of images taken by Curiosity’s Mars Hands Lens Imager on Jan. 23, 2018, during Sol 1943.

2012年8月5日，美国宇航局的好奇号火星车在红色星球上安全着陆。

在这张2018年的自画像中，好奇号位于维拉鲁宾山脊上，火星车一直在调查该山脊。在火星车的正后方是一个富含粘土的斜坡的起点，科学家们急于开始探索。在未来一周，好奇号将开始爬上这个山坡。左边是北面，右边是西面，盖尔陨石坑的边缘在两边的地平线上。

在好奇号桅杆后面突起的是夏普山，在机器人的自拍中被拍到。好奇号五年前登陆火星，目的是研究夏普山底部，它在火星上的所有时间都将留在那里。这座山的底部为我们提供了数百万年形成的岩层。这些岩层是在有水的情况下形成的——可能是由于位于盖尔陨石坑内的山底的一个或多个湖泊。

这幅拼图是由好奇号的火星手镜头成像仪在2018年1月23日即第1943个火星日期间拍摄的几十张图片拼凑而成。
