Mars Express Archive Plans

• Next delivery to ESA/PSA to include data acquired
  through end of 2005
• This delivery was scheduled for fall 2006 with
  data from ASPERA, HRSC, SPICAM, MARSIS, Radio
  Science
• Expect status update at MEX DAWG meeting during
  week of December 4
• The MEX archive group validates the data and
  forwards it to PDS, but they can only send what
  the teams deliver.

Issues and Concerns

• The Mars Express mission lengthened its archive
  validation period from six months to 12 months
  due to lack of staffing. Deliveries are still
  scheduled for every 6 months.
• Data transfers from the PSA to the PDS have been
  problematic.
• Electronic transfer takes a very long time.
• Data bricks in the mail have trouble getting
  through customs.
• PSA is working on an FTP client that will
  automatically send updates to PDS. Progress on
  this tool has been slow.
