Detailed Description (for items identified as
yellow or red)

• We received the ELS parts back from MSSL / Walton
  Plating and completed assembly of the flight
  unit. The unit was then vibrated and cycled in
  thermal vac. The unit just completed
  characterization testing and has only one
  remaining task, measurement of mass properties.
• We are nearing completion of the Acceptance Data
  Package and will be ready for the Pre-Ship Review
  scheduled for March 1.
• DD250s have been submitted to the NMO for both
  the IMA delivery and the upcoming ELS delivery.
• Latest project photos and videos are available on
  Aspera-3 web site.

Accomplishments of the Last Month -ELS

• We received the flight blackened parts from MSSL
  / Walton Plating. The parts looked very good.
  We inspected them and decided to use all of the
  parts from the latest batch. The parts were then
  vacuum baked out prior to assembly.
• The flight unit was assembled for flight and then
  vibrated to protoflight levels.
• Following vibration, a limited functional test
  was performed and the unit was then thermal
  vacuum cycled. Hot and cold starts were
  performed. The unit was left powered on after
  the cold start throughout the temperature
  transitions and plateaus. High voltage was set
  to the maximum level. Everything looked good.
• The unit was then removed from the thermal
  chamber and installed into the characterization
  chamber where the high voltage test was re-run
  followed by the full characterization test. We
  have completed the testing and are currently
  analyzing the data.
• The flight spare was reassembled and installed
  into the characterization chamber. High voltage
  testing was run prior to needing the GSE for the
  flight unit TVAC test.
• This week, the flight spare was reinstalled back
  into the characterization chamber (it was removed
  to perform characterization of the flight unit)
  for its final testing. This will be complete by
  Feb. 27.

Accomplishments of the Last Month - IMA

• The DD250 for delivery of the IMA hardware was
  resubmitted to NMO based on several discussions.
  We are awaiting return copies.

Schedule Summary

• ELS Everything is on track for on-time delivery
  of the flight unit to IRF. The remaining
  activities are to measure the mass prosperities
  of the unit, hold the Pre-Ship Review and hand
  deliver the unit to IRF.
• Software Some software activities have been
  delayed due to hardware activities. The overall
  delivery of the software to support mission
  operations however continues to be on schedule.
• The full-up schedule is available on the ASPERA-3
  Web site.
