One of the largest young craters on Mercury, 114 kilometer (71 mile) diameter Hokusai crater’s bright rays are known to extend across much of the planet. But this mosaic of oblique views focuses on Hokusai close up, its sunlit central peaks, terraced crater walls, and frozen sea of impact melt on the crater’s floor. The images were captured by the MESSENGER spacecraft. The first to orbit Mercury, since 2011 MESSENGER has conducted scientific explorations, including extensive imaging of the Solar System’s innermost planet. Now running out of propellant and unable to counter orbital perturbations caused by the Sun’s gravity, MESSENGER is predicted to impact the surface of Mercury on April 30.

📸 🌌 這幅馬賽克圖像專注於水星上其中一個最大的年輕隕石坑——Hokusai 隕石坑，直徑達 114 公里（71 英里）。Hokusai 的明亮輻射延伸至整個行星，並且能夠令人矚目的看到它的日照中央山峰、階梯狀的坑壁，以及隕石撞擊後形成的冰凍熔融海洋在隕石坑底部。這些圖像由 MESSENGER 太空探測器捕捉。自 2011 年以來，MESSENGER 成為第一個繞水星軌道運行的探測器，進行科學探索，包括對這顆太陽系最內層行星的廣泛成像。由於即將耗盡推進劑，無法抵抗太陽重力造成的軌道擾動，MESSENGER 預計將於 4 月 30 日撞擊水星表面。
