1983年6月,苏联发射了两个金星飞行器——金星-15、-16。这两个飞行器发回的雷达照片证明,金星表面有大型火山、起伏地带和类似山脉或峡谷的带状结构。下图是金星北极区照片,图的右中部是高于起伏地形的大火山口。研究工作者认为,由于熔岩的流动,形成了右侧的较高地势。熔岩继续向左扩展,继而形成巨大带状结构。上图是一座大火山,椭圆形火山口的大小约50×69公
In June 1983, the Soviet Union launched two Venus aircraft - Venus -15, -16. Photographs of the radar sent back by these two aircraft show that the surface of Venus has large volcanoes, undulating strips and ribbon-like structures like mountains or canyons. The picture below shows a photo of the Arctic North Pole. The middle right part of the map is a large crater above the undulating terrain. Researchers believe that due to the flow of lava, a higher topography is formed on the right. Lava continue to expand to the left, and then form a huge ribbon structure. On the map is a large volcano, the size of the oval crater about 50 × 69 male
