We present observations of the power spectral anisotropy in the wavevector space of solar wind turbulence and study how it evolves in interplanetary space with increasing heliocentric distance. We use magnetic field measurements from the Helios 2 spacecraft within 1 AU. To derive the power spectral density (PSD) in the (k{sub Parallel-To }, k ) space based on single-satellite measurements is a challenging task that had not been accomplished previously. Here, we derive the spectrum PSD{sub 2D}(k…

TLDR
The anisotropy of turbulence in the fast solar wind, between the ion and electron gyroscales, is directly observed using a multispacecraft analysis technique, in broad agreement with critically balanced whistler and kinetic Alfvén wave predictions.

Evidence of a cascade and dissipation of solar-wind turbulence at the electron gyroscale.
TLDR
The first direct determination of the dissipation range of magnetofluid turbulence in the solar wind at the electron scales is reported and a remarkable agreement with theoretical predictions of a quasi-two-dimensional cascade into Kinetic Alfvén Waves (KAW).

Wave-vector dependence of magnetic-turbulence spectra in the solar wind.
TLDR
From the three-dimensional energy distribution wave vector anisotropy is estimated with respect to directions parallel and perpendicular to the mean magnetic field, and the result suggests the dominance of quasi-two-dimensional turbulence toward smaller spatial scales.
