它在火星表面移动——它是什么？沙尘暴。这种旋转的上升气流柱被温暖的地表加热，在地球上温暖干燥的地区也很常见。沙尘暴通常只持续几分钟，当它们卷起松散的红色尘埃时，就会变得可见，而下面更暗、更重的沙子则完好无损。尘卷风不仅看起来很酷——它们可以留下可见的痕迹，而且被认为是太阳能电池板表面意想不到的清洁。这段人工智能插值视频中的图像是8月初由毅力号火星车拍摄的，该火星车目前正在耶泽洛陨石坑寻找古代生命的迹象。这段6秒的延时视频包含了一分钟多一点的真实时长。从远处可以看到，旋转的尘暴估计以每小时20公里的速度经过，并延伸到大约2公里的高度。你的天空惊喜：APOD在你的生日上展示了什么照片？(1995后)

It moved across the surface of Mars -- what was it? A dust devil. Such spinning columns of rising air are heated by the warm surface and are also common in warm and dry areas on planet Earth. Typically lasting only a few minutes, dust devils become visible as they pick up loose red-colored dust, leaving the darker and heavier sand beneath intact. Dust devils not only look cool -- they can leave visible trails, and have been credited with unexpected cleanings of the surfaces of solar panels. The images in the featured AI-interpolated video were captured in early August by the Perseverance rover currently searching for signs of ancient life in Jezero Crater. The six-second time-lapse video encapsulates a real duration of just over one minute. Visible in the distance, the spinning dust devil was estimated to be passing by at about 20 kilometers per hour and extend up about 2 kilometers high.
