将静电等离子体湍流转变为电磁的能力具有很好的应用前景，包括积极影响近地等离子体状态的可能性，也就是空间天气。这种双重（静电/电磁）性质是等离子体湍流的基本性质，尚未得到很好的探索，但可以解释许多现象，包括可以放大湍流能量的谐振腔的形成。即将到来的火箭释放湍流空间测量（SMART）使命旨在了解等离子体湍流的演变及其双重性质的非局部后果。这包括能量流入所有可能的波长，以及能量在大的地理体积上的传输。由此产生的波和粒子能量在一个扩展的地理体积中重新分布，形成了一个独特的电磁环境，这对空间天气很重要。
The ability to morph electrostatic plasma turbulence into electromagnetic has promising applications, including the possibility of actively influencing the near‐Earth plasma state, aka the space weather. This dual (electrostatic/electromagnetic) nature is a fundamental property of plasma turbulence, which has not been well explored but could explain many phenomena including the formation of a resonant cavity that can amplify the turbulence energy. The upcoming Space Measurement of A Rocket‐Released Turbulence (SMART) mission is designed to understand the evolution of plasma turbulence and the nonlocal consequences of its dual nature. This includes the flow of energy into all possible wavelengths, as well as the transport of energy over a large geographical volume. The resulting energy redistribution in both waves and particles in an extended geographical volume creates a unique electromagnetic environment, which is important for space weather.
