Some of the central open problems in heliophysics are how the solar corona is heated and how the solar wind is accelerated. Plasma turbulence near the Sun is thought to be one of the key processes involved in answering these questions. The NASA Parker Solar Probe spacecraft is currently on its way to the solar corona making in situ measurements of the solar wind at ever closer distances. This project will make use of this new data, and related plasma theory, to understand the nature of turbulence near the Sun and the role it plays in coronal heating and solar wind acceleration.

太阳物理学中的一些中心悬而未决的问题是太阳日冕是如何被加热的，太阳风是如何被加速的。太阳附近的等离子体湍流被认为是回答这些问题的关键过程之一。美国宇航局的帕克太阳探测器目前正在前往日冕的途中，在更近的距离内对太阳风进行现场测量。该项目将利用这一新数据和相关的等离子体理论，了解太阳附近湍流的性质，以及它在日冕加热和太阳风加速中所起的作用。
