ESA use of Ada

[howell@COMMUNITY-CHEST.MITRE.ORG]

I believe that the European Space Agency (ESA) is using Ada for some
major spaceflight projects, and that HOOD is at least a methodology
being considered within the ESA community.  Can anyone provide a bit
more information, e.g.
    * does ESA mandate Ada for all projects?  If so, is there a waiver
      process, and how did they implement the mandate?

    * has ESA mandated related standards (e.g., methodology to be used,
      or PDL format, or standard interfaces to OS or DBMS services, etc.)

    * what's the current status of Ada use w/in ESA community? (e.g.,
      10 KSLOC pilot projects underway, or 3 MSLOC od running code
      implemented, or.... ?

    * (finally), any set timeframe for ESA to re-evaluate any
      standards decisions that they have mandated?

Thanks a lot for any help you can give; I'm very interested in the
status of Ada use at ESA!
