夸父任务旨在探索造成空间天气的物理过程，补充计划中的现场和地面计划，并为空间天气应用做出重要贡献。夸父包含三艘飞船。 KuaFu-A将位于LI平动点，配备观测太阳极紫外（EUV）和远紫外（FUV）发射以及白光日冕物质抛射（CME）的仪器，并测量无线电波、局部等离子体和磁场以及高能粒子。 KuaFu-B1和KuaFu-B2将位于椭圆极轨道上，其选择是为了便于连续（每周7天，每天24小时）观测北极极光椭圆形和内磁层。夸父任务旨在全球观测从太阳大气层到地球空间的完整扰动链，包括太阳耀斑、日冕物质抛射、行星际云、冲击波及其地理效应，特别关注磁层亚暴和磁暴等剧烈的空间天气事件。任务启动的目标是下一个太阳活动极大期，预计在 2012 年发射。初始任务寿命为 3 年。总体任务设计、仪器补充和最新技术的结合将增进我们对空间天气物理过程的理解，解决包括太阳日冕物质抛射引发、地球磁暴和亚暴机制在内的几个关键的突出问题，并增进我们对日地空间等离子体系统的多尺度相互作用和系统级行为的理解。 (C) 2007 年由 Elsevier Ltd 代表 COSPAR 发布。
The KuaFu mission is designed to explore the physical processes that are responsible for space weather, complementing planned in situ and ground-based programs, and also to make an essential contribution to the space weather application. KuaFu encompasses three spacecraft. KuaFu-A will be located at the LI libration point and have instruments to observe solar extreme ultraviolet (EUV) and far ultraviolet (FUV) emissions and white-light coronal mass ejections (CMEs), and to measure radio waves, the local plasma and magnetic field, and high-energy particles. KuaFu-B1 and KuaFu-B2 will be in elliptical polar orbits chosen to facilitate continuous (24 h per day 7 days per week) observation of the northern polar aurora oval and the inner magnetosphere. The KuaFu mission is designed to observe globally the complete chain of disturbances from the solar atmosphere to geospace, including solar flares, CMEs, interplanetary clouds, shock waves, and their geo-effects, with a particular focus on dramatic space weather events such as magnetospheric substorms and magnetic storms. The mission start is targeted for the next solar maximum with launch hoped for in 2012. The initial mission lifetime will be 3 years. The overall mission design, instrument complement, and incorporation of recent technologies will advance our understanding of the physical processes underlying space weather, solve several key outstanding questions including solar CME initiation, Earth magnetic storm and substorm mechanisms, and advance our understanding of multi-scale interactions in and system-level behavior of our Sun-Earth space plasma system.
