Space plasmas are three-dimensional dynamic entities. Except under veryspecial circumstances, their structure in space and their behavior in time arenot related in any simple way. Therefore, single spacecraft in situmeasurements cannot unambiguously unravel the full space-time structure of theheliospheric plasmas of interest in the inner heliosphere, in the Geospaceenvironment, or the outer heliosphere. This shortcoming leaves numerous centralquestions incompletely answered. Deficiencies remain in at least two importantsubjects, Space Weather and fundamental plasma turbulence theory, due to a lackof a more complete understanding of the space-time structure of dynamicplasmas. Only with multispacecraft measurements over suitable spans of spatialseparation and temporal duration can these ambiguities be resolved. We notethat these characterizations apply to turbulence across a wide range of scales,and also equally well to shocks, flux ropes, magnetic clouds, current sheets,stream interactions, etc. In the following, we will describe the basicrequirements for resolving space-time structure in general, using turbulence'as both an example and a principal target or study. Several types of missionsare suggested to resolve space-time structure throughout the Heliosphere.

The essential role of multi-point measurements in investigations of  turbulence, three-dimensional structure, and dynamics: the solar wind beyond  single scale and the Taylor Hypothesis
