NASA的毅力号火星车抵达耶泽罗撞击坑边缘顶部
前方的道路将在科学上地引人入胜，同时可能也会轻松一些，因为这辆六轮火星车已经完成了漫长的攀登，抵达了顶峰。
火星岩石上的豹斑
Part of a large rock on Mars is shown being mostly orange. On the rock are several irregular light-colored areas surrounded by a dark border. The spots are only millimeters across but might carry big implications. Please see the explanation for more detailed information.
火星上一块大岩石的一部分被显示为橙色。岩石上有几个不规则的浅色区域，周围有一圈深色边框。这些斑点只有几毫米大小，但可能具有重大意义。有关更多详细信息，请参阅说明。
机智号的第40火星日
2021年04月03日 Ingenuity on Sol 39 Image Credit: NASA / JPL-Caltech / MSSS Explanation: The Mars Ingenuity Helicopter, all four landing legs down, was captured here on sol 39 (March 30) slung beneath the belly of the Perseverance rover. The near ground level view is a mosaic of images from the WATSON camera on the rover’s SHERLOC robotic arm. Near the center of the frame the experimental helicopter is suspended just a few centimeters above the martian surface. Tracks from Perseverance extend beyond the rover’s wheels with the rim of Jezero crater visible about 2 kilometers in the distance. Ingenuity has a weight of 1.8 kilograms or 4 pounds on Earth. That corresponds to a weight of 0.68 kilograms or 1.5 pounds on Mars. With rotor…
毅力号360度全景：不寻常的石块和寻找火星生命
2021年03月09日 Perseverance 360: Unusual Rocks and the Search for Life on Mars Image Credit: NASA, JPL-Caltech, ASU, MSSS Explanation: Is that a fossil? Looking through recent images of Mars taken by the new Perseverance rover may seem a bit like treasure hunting, with the possibility of fame coming to the first person to correctly identify a petrified bone, a rock imprinted by an ancient plant, or any clear indication that life once existed on Mars. Unfortunately, even though it is possible that something as spectacular as a skeleton could be identified, most exobiologists think it much more likely that biochemical remnants of ancient single-celled microbes could be found with Perseverance’s chemical analyzers. A key reason is that multicellular organisms may take a greater amount of…
