【环球时报报道 记者 李迅典】作为我国首个太阳专属"摄影师"，中国首颗太阳探测科学技术试验卫 星"羲和号"自2021年10月14日发射以来，已开创5项国际突破，生成科学数据约1.2Pbit。这颗以中国太 阳女神命名的卫星正在距地球平均高度为517公里的太阳同步轨道上，以平均每95分钟绕地球一圈的速 度持续运行。"羲和号"首席科学家、南京大学教授丁明德日前在接受《环球时报》记者采访时用CT扫 描形象地比喻称："羲和号"不到一分钟就可以给整个太阳大气做一次具有300多层切片的三维CT成像观 测。不仅如此，中国更多太阳探测计划也正加速推进。 "羲和号"示意图 （受访者供图） 太阳专属的中国牌"CT扫描仪" 在浩渺太空中，传统卫星的微振动问题长期困扰着高精度观测。丁明德对记者说："传统卫星平台存在 微振动'难测、难控'的技术难题，平台舱飞轮、陀螺等活动部件的振动会不可避免地传递至载荷舱，造 成相机观测质量下降。" 来源：环球时报 2024年"羲和号"的另一项科学发现也震动国际学界——捕捉到罕见的X1级白光耀斑。丁明德对《环球 时报》记者表示："白光耀斑的最大科学难题是其加热和辐射机制，学界长期存在争议。初步研究发现 ...

Core Insights - The Parker Solar Probe has successfully completed another close flyby of the Sun, reaching a distance of approximately 6.2 million kilometers from the solar surface, and traveling at a speed of about 687,000 kilometers per hour, setting new distance records since late last year [1][3] - The probe aims to gather data on the solar atmosphere and solar wind, addressing scientific questions regarding the high temperature of the corona, the acceleration of solar wind, and the origins of high-energy solar particles [2][4] Group 1: Parker Solar Probe's Mission and Achievements - Since its launch in August 2018, the Parker Solar Probe has conducted 24 close flybys of the Sun, leading to significant discoveries such as the magnetic field reversal structure of solar wind and the confirmation of a dust-free zone near the Sun [3] - The probe is equipped with four advanced instruments designed to measure various physical parameters of solar wind and capture images of solar disturbances, ensuring its functionality under extreme solar radiation through a specially designed thermal protection system [2][3] Group 2: Solar Activity and Its Implications - The Sun exhibits an approximately 11-year cycle of activity, currently in its 25th solar cycle, characterized by an increase in sunspot numbers and complex magnetic structures, leading to frequent solar flares and coronal mass ejections that significantly impact the Earth's space environment [3][4] - Other international missions, including the European Solar Orbiter and China's Kuafu-1 and Xihe satellites, are also observing solar activity to enhance understanding of solar phenomena and improve predictive capabilities regarding solar storms, which can affect critical infrastructure on Earth [4]
