Steve, did you log in before looking? At the moment I believe that the calendar entries are set to be invisible unless you log in.
The Acton launch in the dropdown will only be visible if you log in... I believe that's true of the launches in Acton in the calendar... Unless there are additional limitations that I am not sure are there!
Once the full launch calendar is available (we're waiting still on amesbury dates) The calendar items and launch announcements in the dropdown will become generally available not requiring a log in...
