Is Ubuntu Core used in satellites?

Canonical marketing often hints that Ubuntu Core is used by the European Space Agency. Example:

the European Space Agency now has an app-enabled satellite communication network open for developers to create a variety of applications for widespread adoption, both powered by snaps on Ubuntu Core.


When I try to search more information on this, however, the only thing I find is the LimeSDR mini announcement. This announcement is not entirely clear where Ubuntu Core is being used. Is this only on the dev boards or are there also plans for putting this inside of satellites? Is it possible to clarify this?

Should we interpret the Canonical statements as “Ubuntu Core will be used to communicate to satellites” or “Ubuntu Core will be used in satellites.”?
