派克太阳探测器(英语:Parker Solar Probe,缩写:PSP)又译帕克太阳探测器,简称派克号或帕克号,旧称太阳探测器(Solar Probe)或太阳探测器 +(Solar Probe Plus 或 Solar Probe+)[8],是NASA于2018年发射的无人航天器,其任务是反复的探测和观察太阳的外日冕[3][9][6]。它将在2025年最接近太阳,与太阳中心距离仅有9.86太阳半径(690万公里或430万英里)[10][11],届时的速度高达690,000 km/h(430,000 mph),或是光速的0.064%[10][12]。
这个项目在2009财政年度宣布,该项目的费用为15亿美元。由约翰·霍普金斯大学 应用物理实验室设计和制造的这艘航天器[13]于2018年8月12日发射[2]。它以芝加哥大学名誉教授,物理学家尤金·派克的名字命名,以表彰他对太阳物理学的贡献;这是NASA首次以在世人物的名字作为任务的正式名称[14]。

August 2018; sie soll am 24. Dezember 2024 erstmals ihren sonnennächsten Punkt (Perihel) erreichen.[3] Benannt wurde die Sonde nach dem US-amerikanischen Astrophysiker Eugene N.
