Changes affected from mapping changes have lower priority than wikipedia
edits.
These changes usually involve huge number of article updates (e.g. 2K in
this case) and there are probably other mapings updates pending
At the moment Live is ~1 day back (11/5) but processes ~ 1-1.5K
pages/minute so you should see the number increasing gradually after a
while.
Also consider adding more property mappings in the spaceflight infobox

http://en.wikipedia.org/wiki/Template:Infobox_spaceflight
