Cluster Master Science Plan


The Master Science Plan is an important and critical part of the process of planning Cluster science operations. It provides the strategic view of the acquisition of science data by the four Cluster spacecraft, e.g. in terms of scientific targets.

Detailed views of the Plan

These are expanded views each showing the equivalent of two hours of local time in the precession of the Cluster orbits (local times are referenced to that at apogee). The expanded scale allows more detail to be shown, e.g. location of TDA8 periods (WBD downlink to Panska Ves). These plots are now available on the JSOC wiki.

Important: Since 2012, Cluster science requirements have led us (occasionally) to schedule a significant number of BM1 and BM2 periods at different times on each spacecraft, e.g. because of large spacecraft separations, and because of the need for careful targeting of BM2 on the auroral acceleration region. Due to the design of the JSOC software that handles the four-spacecraft Master Science Plan, these single spacecraft operatons cannot be represented in the Bryant plots shown on this web page or in the ASCII table of the Master Science Plan. See the JSOC wiki for details of these single spacecraft periods, and any no-data-taking periods.
