NASA 的“好奇号”火星车持续在火星进行探测,近期在 96 英里宽的盖尔陨石坑内拍摄了令人惊叹的高分辨率图像。2026 年 6 月 11 日,火星车拍摄了“米拉弗洛雷斯”(Miraflores),这是一座 20 英尺高、顶部覆盖着沙子的孤峰,以及一片覆盖在曾经的古海床底部、像蜂窝一样的“多边形之海”。 这些由多次曝光拼接而成的图像,展现了人眼所见般的火星地貌。科学家认为,这些地质构造可能蕴含着关于这颗行星历史的关键线索。自 2014 年以来,“好奇号”一直在攀登 18,000 英尺高的夏普山,目前已发现了碳基分子(生命的基石),这表明古老的火星具备支撑生物生存的必要化学条件。尽管目前尚不清楚这些分子是源于生物过程还是地质过程,但火星车持续开展的工作对于解读火星曾经的水文历史至关重要。

A large, conical rock formation sits in a vast, rocky Martian landscape covered in scattered stones and wind-swept sand dunes.

Trundling around on an alien planet some 140 million miles from Earth is the solar system’s most intrepid landscape photographer, snapping awe-inspiring shots as it scrambles up a mountain that’s inside a crater.

NASA’s Curiosity Rover doesn’t get the praise it deserves, primarily because it is a robot. But every now and then, it is worth pausing to marvel at the imagery this plucky rover is capable of capturing.

Case in point is this image that Curiosity captured on the 4,923rd Martian day, or sol. On Earth, it was June 11, 2026.

Curiosity captured 11 individual photos with its Mast Camera of a sand-capped butte, nicknamed “Miraflores.” The isolated hill is estimated to be roughly 20 feet (6 meters) tall. The butte was left behind as surrounding rock eroded away over time, deepening the broad valley Curiosity is climbing through.

Those 11 photos were sent back to Earth and stitched together. As is often the case with panoramas, NASA scientists weren’t quite able to fill the frame perfectly with the image data, but nevertheless produced a high-resolution panoramic (6,162 x 2,576 pixels) that can be zoomed in on to reveal outstanding details.

The color was adjusted to match the lighting conditions as the human eye would see it if a person were standing on the surface of the Red Planet.

The butte is surrounded by thousands of Martian polygons on the floor, which is thought to be an ancient seabed. These honeycomb-like textures are each about 1.5 to 3 inches (4 to 8 centimeters) across.

The polygonal shapes spread in all directions for as far as the rover can see. They even wrap around the sides of the nearby butte nicknamed Miraflores.

“We’ve seen a lot of fascinating landscapes through Curiosity’s eyes, but this sea of polygons took our breath away,” says the mission’s project scientist, Ashwin Vasavada of NASA’s Jet Propulsion Laboratory in Southern California. “We measured their shapes and chemistry carefully and are hopeful there are clues in the data as to how these features formed.”

The butte and the polygons are both inside the 96-mile-wide Gale Crater, in which sits Mount Sharp, an 18,000-foot-high central peak that rises from the crater.

“Billions of years ago, lakes and streams dappled the lower foothills of Mount Sharp, a 3-mile-tall (5-kilometer-tall) mountain that Curiosity has been ascending since 2014,” NASA explains.

“The rover has previously uncovered chemistry left over from Mars’ watery history, including carbon-based molecules believed to be precursors to RNA and DNA, two nucleic acids that carry genetic information. Scientists have no way of knowing whether these organic molecules were created by biologic or geologic processes — either path is possible — but their discovery reconfirmed that ancient Mars had the right chemistry to support life.”
