An approach to space plasma physics is discussed which uses theories based on laboratory and in situ magnetospheric plasma experiments. General properties of space plasmas are examined, including electrostatic double layers which reportedly invalidate the concept of 'frozen-in' magnetic fields, plasma energy transfer via electric currents, the critical-velocity phenomenon, genuine plasma turbulence, chemical-separation mechanisms, ionizing processes not associated with UV starlight, and the role of dust in interstellar plasmas. The hydromagnetics of interstellar plasma clouds is analyzed in general and in three special cases; consideration is given to electromagnetic pressure effects, force-free magnetic fields, and the production of filaments. It is shown that magnetic fields, which have generally been regarded as obstructing the condensation of interstellar clouds, will promote the contraction of such clouds under certain conditions and may even constitute the main mechanism for contraction. A star-formation process involving gravitational sedimentation of dust into a dusty 'stellesimal' is described.
