2022年9月17日 Perseverance in Jezero Crater’s Delta Image Credit: NASA, JPL-Caltech, MSSS, ASU Explanation: The Perseverance rover’s Mastcam-Z captured images to create this mosaic on August 4, 2022. The car-sized robot was continuing its exploration of the fan-shaped delta of a river that, billions of years ago, flowed into Jezero Crater on Mars. S...
2022年2月25日 Perseverance Sol 354 Image Credit: NASA, JPL-Caltech, Processing: Kenneth Kremer Explanation: This Navcam mosaic from Perseverance looks out over the car-sized rover’s deck, across the floor of Jezero crater on Mars. Frames used to construct the mosaic view were captured on mission sol 354. That corresponds to Earth calendar date February 17...
2021年8月28日 Mars Rock Rochette Image Credit: NASA, JPL-Caltech Explanation: Taken on mission sol 180 (August 22) this sharp image from a Hazard Camera on the Perseverance rover looks out across a rock strewn floor of Jezero crater on Mars. At 52.5 centimeters (21 inches) in diameter, one of the rover’s steerable front wheels is at lower left in the fram...
毅力号火星车用它的导航摄像机拍摄到了这张俯瞰塞塔（Séítah）地区的照片。7月5日，机智号直升机在第九次飞行中飞越了该地区。 资料来源：NASA/JPL-Caltech 这一周，火星直升机团队的忧虑加剧，因为我们为机智号准备了一次重大的飞行挑战。这次飞行发生在太平洋时间7月5日星期一凌晨2点03分，我们上传了飞行指令，然后紧张地等待当天早上晚些时候从火星发回的结果。当我们得知机智号在完成跨越2051英尺(625米)挑战性地形的旅程后，地面控制室里的人都兴高采烈。 第9次飞行与之前的飞行不同。它打破了我们在飞行时间和巡航速度方面的记录，而且在两个机场之间的飞行距离几乎翻了四倍。但真正使这次飞行与众不同的是机智号在2分46秒的空中飞行中必须经过的地形——一个被称为塞塔的地区，用像毅力号火星车这样的地面交通工具很难...
2021年07月01日 Perseverance Selfie with Ingenuity Image Credit: NASA, JPL-Caltech, MSSS Explanation: On sol 46 (April 6, 2021) the Perseverance rover held out a robotic arm to take its first selfie on Mars. The WATSON camera at the end of the arm was designed to take close-ups of martian rocks and surface details though, and not a quick snap shot of friends and...
2021年04月20日 Ingenuity: First Flight over Mars Video Credit: NASA, JPL-Caltech, ASU, MSSS Explanation: What’s the best way to explore Mars? Perhaps there is no single best way, but a newly demonstrated method shows tremendous promise: flight. Powered flight has the promise to search vast regions and scout out particularly interesting areas for more deta...
2021年03月13日 SuperCam Target on Ma’az Image Credit: NASA/JPL-Caltech/LANL/CNES/CNRS Explanation: What’s the sound of one laser zapping? There’s no need to consult a Zen master to find out, just listen to the first acoustic recording of laser shots on Mars. On Perseverance mission sol 12 (March 2) the SuperCam instrument atop the rover’...
2021年03月06日 Perseverance Takes a Spin Image Credit: NASA, JPL-Caltech, Mars 2020 Explanation: After arriving at Jezero Crater on Mars, Perseverance went for a spin on March 4. This sharp image from the car-sized rover’s Navcam shows tracks left by its six wheels in the martian soil. In preparation for operations on the surface of the Red Planet, its fi...
2021年03月02日 Ingenuity: A Mini-Helicopter Now on Mars Illustration Credit: NASA, JPL-Caltech, Mars 2020 – Perseverance Explanation: What if you could fly around Mars? NASA may have achieved that capability last month with the landing of Perseverance, a rover which included a small flight-worthy companion called Ingenuity, nicknamed Ginny. Even though Gi...
2021年02月27日 Perseverance Landing Site from Mars Reconnaissance Orbiter Image Credit: NASA/JPL-Caltech/MSSS Explanation: Seen from orbit a day after a dramatic arrival on the martian surface, the Perseverance landing site is identified in this high-resolution view from the Mars Reconnaissance Orbiter. The orbiter’s camera image also reveals the location...
