NASA 的“好奇号”火星车拍摄的一幅全景图近日公布，以迄今最细致的视角展现了远处被风侵蚀塑造的火星岩崖，突出呈现了任务科学团队长期以来一直盼望近距离观察的地貌特征。这幅景象拍摄于火星当地时间上午8时30分，前景呈现出醒目的蓝色调，明亮的晨光则照亮了地平线上被称为雅丹的岩崖。
这幅全景图由“好奇号”的桅杆相机（Mastcam）于8月11日，也就是任务的第4,982个火星日（sol）拍摄，由六张单独的图像传回地球后拼接而成。与“好奇号”桅杆相机拍摄的大多数图像不同，这幅图像在处理时没有进行白平衡校正，保留了清晨时分的景象。
雅丹层在夏普山西北部绵延约10英里（16公里）。夏普山高3英里（5公里），“好奇号”自2014年以来一直在攀登这座山。事实上，火星车最近又跨过了攀登途中的一个里程碑，爬升高度达到0.6英里（1公里），创下了火星上迄今最高的爬升纪录。随着火星车不断接近这些雅丹，任务科学团队预计将获得更加令人惊叹的影像，也希望能找到这些岩崖是如何形成的答案。
夏普山由多个地层构成，每一层都记录着火星历史上一个不同的时期。通过研究这些地层，科学家们进一步了解了数十亿年前曾覆盖这颗红色星球这一区域的湖泊与溪流。最终，水体干涸，留下了盐类矿物。在新的物质不再沉积到这座山上之后，山上的部分物质可能被风剥蚀，从而形成了雅丹。
“雅丹层显得格格不入。它的颜色不对，地层以奇怪的角度倾斜，看起来几乎像是糊上去的，”位于加利福尼亚州南部的 NASA 喷气推进实验室“好奇号”项目科学家阿什温·瓦萨瓦达（Ashwin Vasavada）说。“但这也正是抵达那里令人兴奋的原因。没有人确切知道这个地层是如何形成的，不过有一种观点认为，它可能是古代火山喷发后沉积下来的火山灰。”
“好奇号”目前正处于第五次延长任务的第二年，这次延长任务以探索蛛网般的箱状构造脊（boxwork ridges）为开端。在接下来一年左右的大部分时间里，火星车将穿行于富含硫酸盐和碳酸盐的地层，这两类矿物都是古代地表干涸的迹象。科学家们希望在2027年的某个时候抵达雅丹底部，届时“好奇号”将能利用机械臂，采集有关这些神秘地貌的独一无二的数据。

NASA’s Curiosity Rover Catches Stunning Martian Dawn - NASA
A newly released panorama captured by NASA’s Curiosity rover offers the most detailed view yet of distant, wind-carved Martian cliffs, highlighting features the mission’s scientists have long been waiting to see up close. The scene was snapped at 8:30 a.m. local Mars time, showing striking blue hues in the foreground as bright morning light illuminates crags known as yardangs on the horizon.
The panorama was captured by Curiosity’s Mastcam on Aug. 11, the 4,982nd Martian day, or sol, of the mission, and comprises six individual images that were stitched together after being sent to Earth. Unlike most of Curiosity’s Mastcam images, this one was processed without white balancing, preserving the early morning appearance.
The yardang layer extends roughly 10 miles (16 kilometers) across the northwestern reaches of Mount Sharp, a 3-mile-tall (5-kilometer-tall) mountain that Curiosity has been ascending since 2014. In fact, the rover recently passed another milestone in its ascent, reaching 0.6 miles (1 kilometer) of elevation — the most ever climbed on Mars. As it draws ever-closer to the yardangs, mission scientists expect to get even more amazing imagery — and, they hope, answers to how these cliffs were created.
Mount Sharp is made up of layers, each recording a distinct period of Mars’ history. By studying them, scientists have been able to learn more about lakes and streams that covered this part of the Red Planet billions of years ago. Eventually, the water dried up and left salty minerals behind. After new material stopped settling on the mountain, some of it may have been stripped away by wind, giving rise to the yardangs.
“The yardang layer looks out of place. It’s the wrong color, the layers tilt at an odd angle, and it almost appears plastered on,” said Ashwin Vasavada, Curiosity project scientist of NASA’s Jet Propulsion Laboratory in Southern California. “But that’s what makes it exciting to reach. No one is sure exactly what created this layer, but one idea is it may be ash deposited by ancient volcanic eruptions.”
Curiosity is in the second year of its fifth extended mission, which started with an exploration of the spiderweb-like boxwork ridges . The rover will spend most of the next year or so driving through layers enriched with sulfates and carbonates, both signs of ancient drying on the surface. Sometime in 2027, scientists hope to reach the base of the yardangs, where Curiosity will be able to use its robotic arm to collect one-of-a-kind data on these mysterious features.
