Roamingly on the Rustic half diameter planet size Red planet Mars on Hong Kong SAR- Beijing Earth Wednesday time… In which new mileage: “Zhu Rong” Mars Rover ….Sailing in the galaxy, strolling through the glamorous rustic environment in talking it’s adventure with Tianwen 1 Martian communications probe orbiting the Red Planet… in which “Zhurong” Mars rover completes scheduled exploration mission…
日凌结束，天问一号恢复科学探测Sun Ling ends, Tianwen No.1 resumes scientific exploration
In late September 2021, the Earth, Mars and the three sides to the sun almost in a straight line, a phenomenon known as Ling day. During this period, the communication between the Mars rover and the earth was disturbed by the sun’s electromagnetic radiation, which was unstable or even interrupted. During the transit period, the “Tianwen-1” orbiter and the “Zhurong” Mars rover entered autonomous operation mode and suspended scientific exploration work. In order to find out the actual impact of Riling, the engineering development team continued to carry out measurement and control link tracking tests, and for the first time obtained measured data on the interference of deep-space measurement and control communications under Riling, and accumulated first-hand data and engineering experience for subsequent tasks to deal with Riling.
2021年9月下旬开始，地球、火星运行到太阳的两侧且三者近乎处于一条直线，这种现象称作日凌。在此期间，火星探测器与地球的通信受到太阳电磁辐射干扰，出现不稳定甚至中断。日凌期间，“天问一号”环绕器和“祝融号”火星车进入自主运行模式，暂停科学探测工作。为摸清日凌实际影响，工程研制团队持续开展测控链路跟踪测试，首次获取日凌状态下深空测控通信受干扰情况的实测数据，为后续任务应对日凌积累了一手数据和工程经验。
The astronomical phenomenon of occultation during the solar transit provides scientists with a rare opportunity to observe the solar transit occultation. The Shanghai Astronomical Observatory, the National Space Science Center and other units, together with the European VLBI Institute, the University of Tasmania in Australia and other institutions, used Wettzell and Yebes located in Shanghai, Kunming, Urumqi, and Europe. ), Medicina, Svetloe, Zelenchukskaya, Badary, Hobart, Keith, Russia The radio telescopes in Kath, Yarra, and Hartebeesthoek in South Africa carried out the same beam day for the “Tianwen-1” orbiter and the “Mars Express” orbiter (MEX). Ling observation. A total of about 5 terabytes of data have been obtained in this observation. At present, the parties are conducting joint research. By analyzing the influence of the electromagnetic wave signals transmitted by the two detectors back to the earth through the solar wind, the fluctuations in the interplanetary electron density caused by the intrinsic turbulence of the solar wind are studied. Scientific issues such as the relationship between solar wind micro-turbulence and macro-wind speed.
日凌期间出现掩星天文现象，为科学家提供了难得的日凌掩星观测机会。上海天文台、国家空间科学中心等单位，联合欧洲VLBI研究所、澳大利亚塔斯马尼亚大学等机构，利用分布在上海、昆明、乌鲁木齐，欧洲的韦特策尔（Wettzell）、耶韦斯（Yebes）、梅迪奇纳（Medicina），俄罗斯的斯韦特拉耶（Svetloe）、泽连楚克斯卡雅（Zelenchukskaya）、班达拉（Badary），澳大利亚的霍巴特（Hobart）、凯斯（Kath）、亚拉（Yarra）和南非的哈特比斯特胡克（Hartebeesthoek）等地的射电望远镜，对“天问一号”环绕器和“火星快车”轨道器（MEX）开展同波束日凌观测。本次观测共获取约5TB数据，目前各方正在开展联合研究，通过分析两个探测器传回地球的电磁波信号经过太阳风时受影响情况，研究太阳风内禀湍流引起的行星际电子密度涨落、太阳风微观湍流与宏观风速关系等科学问题。
A few days ago, the solar transit phenomenon has ended, and the measurement and control communication between the probe and the earth has returned to normal. Judging from the telemetry data, the “Tianwen No. 1” was in normal condition during the solar transit and passed the first solar transit safely. The orbiter will enter the remote sensing mission orbit in early November to carry out global remote sensing exploration of Mars to obtain scientific data such as Mars morphology and geological structure, surface material composition and soil type distribution, atmospheric ionosphere, and Martian space environment, while taking into account the development of the rover mission Phase of relay communication.
日前，日凌现象已经结束，探测器与地球之间的测控通信恢复正常，通过遥测数据判断，“天问一号”日凌期间状态正常，安全度过首次日凌。环绕器将于11月初进入遥感使命轨道，开展火星全球遥感探测，获取火星形貌与地质构造、表面物质成分与土壤类型分布、大气电离层、火星空间环境等科学数据，同时兼顾火星车拓展任务阶段的中继通信。
