NASA 好奇号火星车已在火星上行驶了 4000 天，尽管关节有所磨损，但仍然坚强。美国宇航局表示，好奇号火星车在火星上已度过了 4000 天，这台探测车虽然已经出现了一些磨损的迹象，但仍然继续在这颗红色星球上探索。好奇号火星车于 2012 年在盖尔撞击坑着陆，从那以后一直在研究这颗红色星球，以确定古代的火星是否能够支持微生物的生存。好奇号在这些年里钻取了 39 个样本，目前正在向高达 3 英里的夏普山的山脚爬升，以便地质学家能够仔细观察岩石层，了解火星的气候是如何变化的。好奇号火星车的探索之旅并不总是一帆风顺的，十多年里，它在美国宇航局称之为“充满尘埃和辐射的严酷寒冷环境”中行驶了近 20 英里（32 公里），但美国宇航局表示，“好奇号仍然坚强”。目前好奇号的主摄像头的 34 毫米焦距的左相机已经出现了一些问题，钻孔系统和臂关节上也发现了磨损的痕迹，当然，探测车的轮子在碾过火星的表面时也遭受了一些严重的损坏。对于轮子，工程师们承认他们低估了火星表面的条件。不过很多问题已经通过软件更新得到了解决或至少得到了缓解，例如增加了一个牵引力控制算法，有助于减少轮子在尖锐的岩石上的磨损。好奇号已经远远超过了它最初的两年任务时间，但要想达到它的前任——依靠太阳能板的机遇号的惊人寿命，好奇号还有一段路要走。好奇号是由一个放射性同位素热电发电机（RTG）供电的，根据美国宇航局的说法，任务工程师们预计这个核电源还能够让探测车运行“更多年”。由于现在火星从地球的角度看消失在太阳后面，所以和好奇号的通信在 11 月暂停，工程师们预计在 11 月 28 日之后恢复与好奇号的联系。

NASA’s Curiosity Mars Rover has been traveling on Mars for 4000 days, despite some wear and tear. According to NASA, the Mars rover has been exploring the red planet for 4000 days, and although there are some signs of wear and tear, it remains sturdy. The Curiosity Mars Rover landed on Mars in 2012 and has been studying the planet to determine whether ancient Mars could support microorganisms. Over the years, the Curiosity Mars Rover has drilled 39 samples and is currently climbing up to a hill of Sharp Mountain to study rock layers and understand how the climate of Mars has changed. The Curiosity Mars Rover’s exploration journey is not always smooth, having traveled nearly 20 miles (32 kilometers) through the harsh cold environment on the red planet over the past 十多年。However, NASA says that the rover remains sturdy. The main camera’s 34-mm focal length left lens has already shown some issues, and there have also been signs of wear on the probe’s drilling system and arm joints. Of course, the wheels of the Mars rover have also suffered some serious damage as they have rolled over the red planet’s surface. For the wheels, engineers acknowledge that they underestimated the conditions on Mars. However, many problems have been addressed or at least alleviated through software updates, such as adding a traction control algorithm, which helps reduce the wear on the wheels on sharp rocks. The Curiosity Mars Rover has far exceeded its original two-year mission time, but in order to achieve the impressive lifespan of its predecessor, the Opportunity rover, which relied on solar panels, the Curiosity Mars Rover still has some distance to go. The Curiosity Mars Rover is powered by a radioactive isotope thermoelectric generator (RTG), and according to NASA, mission managers expect the nuclear power to keep the rover running for “more years.” Due to the conjunction of Mars and the Earth in the solar eclipse, communication with the Curiosity Mars Rover was suspended in November. Engineers expect to resume contact with the rover by November 28th.
