Shadow of a Martian Robot

Explanation: What if you saw your shadow on Mars and it wasn’t human? Then you might be the Opportunity rover exploring Mars. Opportunity explored the Red Planet from 2004 to 2018, finding evidence of ancient water, and sending breathtaking images across the inner Solar System. Pictured here in 2004, Opportunity looks opposite the Sun into Endurance Crater and sees its own shadow. Two wheels are visible on the lower left and right, while the floor and walls of the unusual crater are visible in the background. Caught in a dust storm in 2018, Opportunity stopped responding, and NASA stopped trying to contact it in 2019 and declared the ground-breaking mission, originally planned for only 92 days, complete.

火星机器人的影子

说明: 如果你在火星上看见自己的影子，而且那不是人类？那么，你或许就是在探索火星的机遇号火星车。机遇号自2004年至2018年间探索了这颗红色星球，并发现了远古液态水的证据，且向内太阳系传回了令人叹为观止的影像。摄于2004年的这张照片中，机遇号背向太阳，望向坚忍撞击坑，并看见了自己的影子。画面左下与右下可以看到两个轮子，而这座奇特撞击坑的坑底与壁面在背景中也清晰可见。于2018年，机遇号遭遇沙尘暴，停止了与外界的联系。2019年，NASA终止了与机会号的联系尝试，并宣布这项原先仅规画92天的开创性任务圆满完成。
