A camera aboard the Mars Reconnaissance Orbiter, called the High Resolution Imaging Experiment, or HiRISE, captured an image of the unusual geological feature in December.
参与设计这款相机的美国亚利桑那大学于1月25日分享了这张照片。
The University of Arizona, which developed the camera with Ball Aerospace, shared the image on January 25.
The “nose” is actually a hill in the shape of the letter V; its “eyes” are two small, lopsided craters, according to the University of Arizona.
看似“熊的头颅”的圆圈,被称为“环形断裂口”。研究人员表示,环形断裂口可能是沉积物覆盖撞击坑后形成的。而“熊鼻子”可能是火山或泥浆喷口(volcanic or mud vent),沉积物可能是熔岩(lava)或泥浆(mudflows)。
The circle making up the “head” — what the university called “the circular fracture pattern” — “might be due to the settling of a deposit over a buried impact crater.”
It speculated: “Maybe the nose is a volcanic or mud vent and the deposit could be lava or mud flows?”
