• Archive and Distribution Segment (ADS) The main
  function of the ADS is to receive and archive
  RDRs, SDRs, and EDRs from the IDPS.

  metadata, upon which users may search, browse,
  and order data.
• Launch Support Segment (LSS) The LSS provides
  those assets and services associated with the
  launch vehicle (LV) and the payload integration.
  
• This segment includes all ground support
  equipment, property, and facilities to integrate
  the spacecraft to the LV, verify their
  integration, and conduct pre-launch testing with
  the remainder of the ground system..

  prototype element of the future NASA Earth
  Science Enterprise distributed science data
  system.
