近日，我国宣布计划于 2026 年发射“羲和二号”日地 L5 太阳探测工程，这将是我国首次尝试在日地 L5 点发射人造探测器。该探测器将用于观测太阳活动现象，三维重构太阳爆发的物理机制，并提前四五天观测到即将面向地球的太阳活动。日地 L5 点是国际探测空白，开展探测将具有重要意义。
“羲和二号”是我国首颗探日卫星“羲和号”后继者，自 2021 年发射以来，已产生超 400TB 的高质量科学数据和一系列原创性科研成果。目前，“羲和二号”日地 L5 太阳探测工程正在论证中，计划于 2026 年发射升空。该探测器的发射将为我国太阳立体探测时代奠定基础，助力揭示太阳爆发的物理机制，为空间天气预报带来革命性突破。
太阳立体探测时代是指通过多角度、多波段观测太阳，实现对太阳活动现象的立体、全面观测的时代。与传统的单一角度观测相比，太阳立体探测可以提供更丰富的太阳信息，为研究太阳活动提供关键信息。此次“羲和二号”日地 L5 太阳探测工程的实施，将为我国太阳探测事业带来飞跃式发展。
我国在太阳探测领域取得了一系列重要成果，包括“东风一号”系列太阳巡视探测器和“夸父一号”太阳黑子和太阳耀斑探测卫星。这些成果为我国太阳立体探测时代奠定了基础，相信“羲和二号”日地 L5 太阳探测工程将会取得更为重要的成果。

Recently, China announced its plan to launch the “Yihe 二号” solar probe in 2026, which will be the first attempt to launch a man-made detector at the solar L5 point. This detector will be used to observe solar activity phenomena, and will provide a 3D reconstruction of the physical mechanism of solar flares. It will also enable the observation of solar activity four to five days in advance, which will bring a revolutionary breakthrough in space forecasting. The solar L5 point is an international detection blank, and the launch of the detector will be of great significance.
The “Yihe 二号” is the follow-up of China’s first solar probe “Yihe 一号，” which has produced more than 400 TB of high-quality scientific data and a series of original scientific research achievements since its launch in 2021. Currently, the verification of the “Yihe 二号” solar probe for the solar L5 project is under way, and it is planned to launch the probe in 2026. The launch of this detector will lay the foundation for China’s new era of solar probe technology, which will enable the study of the physical mechanism of the sun, providing key information for space forecasting.
