Hi Tim,
yes you need to have editor rights on the mappings wiki.
Someone will enable you as soon as possible (@Dimitris?).
Some answers inline.

Statistics are generated periodically from Wikipedia dumps.
I do not remember exactly when the last stats were created, but the
"Infobox spaceflight" should be there...could you issue a bug please?
Anyway, even if it does not appear in the stats page you can still add a
mapping for that Infobox (once you will have editor rights).

The mapping page allows you to map templates and properties into ontology
classes and ontology properties.
The ontology property (class) page allows you to define an ontology
property (class).
