The ideas behind commercialization of Earth photography from space has long been dominated by the analytical value of the imagery. What specific knowledge and actionable intelligence can be garnered from these evermore frequent revisits of the planet\u2019s surface? How can I find a market for this analysis? However, what is rarely considered is what is the educational value of the imagery? As students and children become more aware of our several decades of advance in viewing our current planetary state, we should find mechanisms which serve their curiosity, helping to satisfy our children\u2019s simple quest to explore and learn more about what they are seeing. The following study describes the reasons why current GEO and LEO observation platforms are inadequate to provide truly global RGB coverage on an update time-scale of 5-min and proposes an alternative, low-cost, GEO + Molniya 3U CubeSat constellation to perform such an application.<\/jats:p>","DOI":"10.3390\/rs13050878","type":"journal-article","created":{"date-parts":[[2021,2,26]],"date-time":"2021-02-26T04:36:24Z","timestamp":1614314184000},"page":"878","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Contemporaneous Monitoring of the Whole Dynamic Earth System from Space, Part I: System Simulation Study Using GEO and Molniya Orbits"],"prefix":"10.3390","volume":"13","author":[{"given":"Christopher","family":"Cullingworth","sequence":"first","affiliation":[{"name":"Imaging Group, Mullard Space Science Laboratory, UCL Department of Space &amp; Climate Physics, Holmbury St. Mary, Surrey RH5 6NT, UK"},{"name":"CGI, Keats House Park, Springfield Drive, Leatherhead KT22 7LP, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5077-3736","authenticated-orcid":false,"given":"Jan-Peter","family":"Muller","sequence":"additional","affiliation":[{"name":"Imaging Group, Mullard Space Science Laboratory, UCL Department of Space &amp; Climate Physics, Holmbury St. Mary, Surrey RH5 6NT, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"270","DOI":"10.1111\/j.1467-8306.1994.tb01738.x","article-title":"Contested Global Visions: One-World, Whole-Earth, and the Apollo Space Photographs","volume":"84","author":"Cosgrove","year":"1994","journal-title":"Ann.
