The interplanetary medium provides a vast natural laboratory for studying many fundamental questions about astrophysical plasmas. In this paper I make a short review on what we know about turbulent fluctuations which behave differently at low (f < 1 Hz) and high (f > Hz) frequencies. Particular attention is made about anisotropy at low frequency and its MHD modeling as well as the origin of a second inertial range at high frequencies characterized by steep power law spectra which cannot be associated with MHD fluctuations.
