If you’re a frequent user of Terra data, you’re probably somewhat aware of the recent and upcoming changes to Terra’s “traditional” orbit. (If you weren’t aware of these upcoming changes, or if you just want to read an excellent overview of Terra’s legacy and future, click on the link to read Blumenfeld’s article “From Terra to Terra Firma”).

In efforts to get the news out about Terra’s lowering and drift – and to inform users of potential data impacts resulting from these orbit changes — we’ll be posting several new infographics and short animations on the Terra website, as part of a larger campaign to celebrate over two decades of Terra data. Any graphics posted are available for public use and redistribution. (Click on the image for larger resolution and please share with others!)

Here’s an example of the new graphics we’ll be posting on the site:

This infographic gives a simplified overview of Terra’s orbital movements, from its current drift, through the constellation exit this Fall, and finally into a lower, drifting orbit – along with the estimated (minor) effects possible due to these orbital changes.
