What is that dark sand dune doing on Mars? NASA’s robotic rover Curiosity has been studying it to find out, making this the first-ever up-close investigation of an active sand dune on another world. Named Namib Dune, the dark sand mound stands about 4 meters tall and, along with the other Bagnold Dunes, is located on the northwestern flank of Mount Sharp. The featured image was taken last month and horizontally compressed here for comprehensibility. Wind is causing the dune to advance about one meter a year across the light bedrock underneath, and wind-blown sand is visible on the left. Part of the Curiosity rover itself is visible on the lower right. Just in the past few days, Curiosity scooped up some of the dark sand for a detailed analysis. After further exploration of the Bagnold Dunes, Curiosity is scheduled to continue its trek up the 5-kilometer tall Mount Sharp, the central peak in the large crater where the car-sized rover landed.

🪐✨ 在火星上，有個黑色沙丘正在引起NASA的好奇心！機械探測器Curiosity現在正深入研究呢個叫「Namib Dune」的沙丘，這是人類首次在其他星球對活動沙丘進行詳細調查。Namib Dune高約4米，位於Mount Sharp的西北側，屬於Bagnold Dunes之一。
最近的影像顯示，風力使沙丘每年向前推進約一米，左側可見風吹起的沙粒。而Curiosity探測器的部分也可見於畫面右下角。最近，Curiosity剛剛採集了一些黑色沙子以進行詳細分析。
在探索完Bagnold Dunes後，Curiosity計劃繼續攀登高達5公里的Mount Sharp，這是探測器著陸的巨大隕石坑中的中央山峰。
