NASA and ESA have agreed to cooperate towards preparing a Mission Requirements Document (MRD) and defining support science study activities for a Mass-change And Geosciences International Constellation (MAGIC). Such a constellation is essential for understanding global change. Requirements sources are the ESA/NASA International Gravity Science Working Group (IGSWG) Report (1), the 2017 National Academies of Science Earth Science Decadal Survey (2) and an IUGG document (3), which include community user needs in view of potential future contributions to EC Copernicus services.
The evolution of the MRD will be supported by the Joint Mass Change Mission Expert Group (JMCMEG). The JMCMEG members cover expertise in Earth Science study disciplines. In addition, the group brings expertise from missions like GRACE, GRACE-FO and GOCE, and past or current preparatory studies for future concepts. The group’s expertise is complementary (hydrology, cryosphere, oceanography, solid earth, climate change, neutral atmosphere) so that it can consider a wide breadth of user community objectives, regarding science and applications, as well as more technical aspects of mission design trade-offs. JMCMEG activities will be conducted in the context of the MAGIC concept and supporting scientific study and validation activities. The JMCMEG will also provide support in strengthening the link to the international user communities and their representing Agencies, and support communications on the concept by means of scientific publications, presentations, and the World Wide Web.
This presentation will focus on the latest definition of MAGIC mission requirements and user needs.
