Members of the Perseverance Mars Rover team watch in mission control at NASA’s Jet Propulsion Laboratory as the first images arrive moments after the spacecraft successfully touched down on Mars, Thursday, Feb. 18, 2021. A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rov...
2021年2月18日星期四，美国宇航局毅力号火星车团队成员在位于加利福尼亚州帕萨迪纳市的NASA喷气推进实验室的任务控制中心观看航天器成功着陆火星后的第一批图像。毅力号火星任务的一个关键目标是天体生物学，包括寻找古代微生物生命的迹象。探测器将描述火星的地质和过去的气候，为人类探索火星铺平道路，并将成为第一个收集和封存火星岩石和风化层的任务。 影像来源：NASA/Bill Ingalls 在经历了203天的行程，穿越了2.93亿英里（4.72亿公里）之后，NASA最大、最先进的火星车已于周四登陆火星。美国东部标准时间下午3:55（太平洋标准时间下午12:55），美国宇航局位于南加州的喷气推进实验室的任务控制中心宣布成功着陆。 2020年7月30日，充满突破性技术的火星2020任务从佛罗里达州卡纳维拉尔角空间站发射...
During the Mars Perseverance engineering and technology overview on Tuesday, Feb. 16, 2021, at NASA’s Jet Propulsion Laboratory, chief engineer Adam Steltzner displays a rover wheel. The Perseverance Mars rover is due to land on the Red Planet on Thursday, Feb. 18, 2021. A key objective for Perseverance’s mission is astrobiology, including the search f...
In New York City on Tuesday, Feb. 16, 2021, the Empire State Building is illuminated in red to celebrate this Thursday’s scheduled landing on Mars of NASA’s Perseverance rover. A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geol...
If we find life on the Red Planet, we’ll have astrobiologists like Dr. Kennda Lynch to thank. Lynch is an astrobiologist and geomicrobiologist studying life in extreme environments on Earth as models for characterizing habitable environments and searching for biosignatures on other planetary bodies in our solar system and elsewhere. Prior to obtaining ...
With its heat shield facing the planet, NASA’s Perseverance rover begins its descent through the Martian atmosphere in this illustration. Hundreds of critical events must execute perfectly and exactly on time for the rover to land on Mars safely on Feb. 18, 2021. Entry, Descent, and Landing, or “EDL,” begins when the spacecraft reaches the top of the M...
This illustration shows Jezero Crater — the landing site of the Mars 2020 Perseverance rover — as it may have looked billions of years go on Mars, when it was a lake. An inlet and outlet are also visible on either side of the lake. A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial li...
