20世纪60年代到70年代,美国宇航员多次成功登陆月球,并将国旗插在月球表面的土壤中。对此,科学家们猜想:现在这些国旗是否还存在?美国国家航空航天局(NASA)月球探测器发回的照片显示,尽管几十年的时间过去了,部分美国国旗仍然屹立在月球上。在20世纪60年代到70年代美国的6次登月之旅中,每一次宇航员都会在月球表面插上一面美国国旗作为美国成功登月标志。月球探测器发回的最新高分辨率图像显示,随着月球围绕自己的轨道运行,这些美国国旗产生了阴影,据此科学家得出了它们还处于直立状态的结论。月球卫星项目的研究者马克·罗宾逊在接受媒体采访时说:“从这些照片中我们可以 From the 1960s to the 1970s, astronauts successfully landed on the moon many times and inserted the national flag in the soil on the moon’s surface. In response, scientists speculated: Are these national flags still present? Photographs returned by the NASA lunar probe show that although decades have passed, some American flags still stand on the moon. During the six trips to the United States on the moon during the 1960s and 1970s, each astronaut put a U.S. flag on the surface of the moon as a sign of the success of the United States. The latest high-resolution images sent back by the lunar probe show that as the moon moves around its orbit, these American flags have shaded, and scientists conclude that they are still upright. Mark Robinson, researcher of the lunar satellite project, said in an interview: ”From these photos, we can
