NASA recently released a photo of a large blue sand dune on Mars showing "a more complex structure" than dunes surrounding it.

美国宇航局最近发布了一张火星上的大型蓝色沙丘的照片，该沙丘显得“比周围的沙丘结构更复杂”。

The striking image of the turquoise blue dune on the Red Planet was captured on Jan. 24 by NASA’s Mars Reconnaissance Orbiter’s camera, managed by the University of Arizona, Tucson.

1月24日，美国国家航空航天局的火星勘测轨道飞行器的相机拍摄了红色星球上绿松石蓝色沙丘的惊人图像，该图像由图森亚利桑那大学管理。

The dune was spotted on Mars’ Lyot Crater region. Researchers suspect it might be made of finer material than nearby dunes, according to a news release. MRO, which blasted into space in 2005, is studying the history of water on Mars.

沙丘在火星Lyot火山口地区被发现。据新闻报道，研究人员怀疑它的构成材料可能比附近的沙丘的更加细腻。 在2005年进入太空的火星勘测轨道飞行器正在研究火星上的水的历史。

NASA’s Curiosity Mars rover has previously shown Mars is home to sand dunes the size of football fields as well as small sand ripples.

美国宇航局的“好奇号”火星车之前曾显示，火星上布满了沙丘，大的有足球场的规模，小的如同涟漪。

The planet is currently battling a massive sandstorm that has silenced NASA’s solar-powered Opportunity rover. NASA’s Curiosity rover, which has not been affected continues to collect data, and even posed for a dusty "selfie."

这颗行星正在经历一场巨大的沙尘暴，这场沙尘暴使美国宇航局的太阳能“机遇号”漫游车沉没。美国宇航局的“好奇号”探测器未受影响，仍在收集数据，甚至在尘土飞扬中“自拍”。
