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 of the Mars 2020 mission descent stage, heat shield, and parachute and back shell that delivered Perseverance to the surface of Mars. Each annotated inset box spans 200 meters (650 feet) across the floor of Jezero Crater. Perseverance is located at the center of the pattern created by rocket exhaust as the descent stage hovered and lowered the rover to the surface. Following the sky crane maneuver, the descent stage itself flew away to crash at a…

2021年02月26日 Mars Perseverance Sol 3 Image Credit: NASA, JPL-Caltech, MSSS, ASU Explanation: Stitched together on planet Earth, 142 separate images make up this 360 degree panorama from the floor of Jezero Crater on Mars. The high-resolution color images were taken by the Perseverance rover’s zoomable Mastcam-Z during mission sol 3, also known as February 21, 2021. In the foreground of Mastcam-Z’s view is the car-sized rover’s deck. Broad light-colored patches in the martian soil just beyond it were scoured by descent stage rocket engines during the rover’s dramatic arrival on February 18. The rim of 45 kilometer-wide Jezero Crater rises in the distance. In the coming sols, Perseverance will explore the ancient lake-delta system in the crater, hunting for signs of past microscopic life and…

2021年02月23日 Video: Perseverance Landing on Mars Video Credit: NASA/JPL-Caltech, Mars 2020 Mission Team Explanation: What would it look like to land on Mars? To better monitor the instruments involved in the Entry, Decent, and Landing of the Perseverance Rover on Mars last week, cameras with video capability were included that have now returned their images. The featured 3.5-minute composite video begins with the opening of a huge parachute that dramatically slows the speeding spacecraft as it enters the Martian atmosphere. Next the heat shield is seen separating and falls ahead. As Perseverance descends, Mars looms large and its surface becomes increasingly detailed. At just past 2-minutes into the video, the parachute is released and Perseverance begins to land with dust-scattering rockets. Soon the Sky Crane…

2021年02月20日 Perseverance: How to Land on Mars Image Credit: NASA, JPL, Mars 2020 Explanation: Slung beneath its rocket powered descent stage Perseverance hangs only a few meters above the martian surface, captured here moments before its February 18 touchdown on the Red Planet. The breath-taking view followed an intense seven minute trip from the top of the martian atmosphere. Part of a high resolution video, the picture was taken from the descent stage itself during the final skycrane landing maneuver. Three taut mechanical cables about 7 meters long are visible lowering Perseverance, along with an electrical umbilical connection feeding signals (like this image), to a computer on board the car-sized rover. Below Perseverance streamers of martian dust are kicked-up from the surface by the descent…

2021年02月19日 Mars Perseverance Sol 0 Image Credit: NASA, JPL, Mars 2020 Explanation: After a 203 day interplanetary voyage, and seven minutes of terror, Perseverance has landed on Mars. Confirmation of the successful landing at Jezero crater was announced from mission control at NASA’s Jet Propulsion Laboratory in Southern California at 12:55 pm PST on February 18. The car-sized Mars rover’s Front Left Hazard Avoidance Camera acquired this initial low resolution image shortly after touchdown on mission Sol 0. A protective cover is still on the camera, but the shadow of Perseverance, now the most ambitious rover sent to the Red Planet, is visible cast across the martian surface. Tomorrow’s picture: light-weekend 毅力号火星车的第一天 影像提供: NASA, JPL, Mars 2020 说明: 经过203天的行星际旅程，以及恐怖7分钟之旅后，毅力号着陆在火星上。在太平洋标准时间2月18日午后12:55，位在南加州的美国航太总署．喷射推进实验室的任务控制中心，正式确认在耶杰罗坑的著陆成功。着陆后不久，这部房车大小的火星车之左前避险相机，拍下了上面这幅初期低解析影像，标志这部火星车火星历的第一天。虽然相机仍在保护罩内，不过在影像里，仍可清楚见到这部空前的毅力号火星车，在火星表面投下的身影。 明日的图片: light-weekend
