Astronomy Picture of the Day——蒂尔岭上的好奇号
Curiosity at Teal Ridge

Explanation: Part of a 360 degree panorama, this view looks out from the Mars rover Curiosity's current location on the Red Planet dubbed Teal Ridge. The mosaicked scene was captured by the rover's Mastcam on Earth calendar date June 18, 2019. That corresponds to Curiosity's sol 2440, or 2,440th martian day on the surface. Since landing seven years ago on August 6, 2012 in Gale Crater, Curiosity has traveled some 21 kilometers (13 miles). On the right, the rover's tracks lead back toward Vera Rubin Ridge with the Gale Crater rim visible in the distance. The robotic rover leaves wheel tracks about 3 meters (10 feet) apart. During its mission, Curiosity has had great successes exploring the history of water in the martian environment. In fact, NASA's Mars 2020 rover is largely based on the Mars Curiosity rover design.
蒂尔岭上的好奇号
这幅影像是一幅360度全景图的一部分，是好奇号目前所在红色星球上被称为蒂尔岭的位置。这幅拼接图像是在2019年6月18日由探测车的全景摄像机拍摄的，这是好奇号在火星工作的第2440天。自7年前的8月6日在盖尔环形山着陆以来，好奇号已经行驶了约21公里。在该影像右侧，探测车的行驶轨迹指向维拉鲁宾山脊方向，远处还可见盖尔环形山的边缘。探测车留下的两条车轮轨迹之间相距约3米。在执行任务期间，好奇号在探测火星环境中水的历史方面取得了巨大成就。实际上，NASA将在2020年发射的Mars 2020火星探测车主要是以好奇号火星探测车为基础进行设计的。
