Description of Driving Event:
Need to Upgrade International Space Station (ISS) Command and Data Handling (C&DH) Components as Soon as Possible
Lesson(s) Learned:
The planning process for computer upgrades for the ISS has begun. Several possible upgrades are being discussed, such as replacing the Mass Memory Unit, upgrading the processor, upgrading the compiler used, and replacing the Portable Computer Systems (PCS).
Recommendation(s):
NASA should proceed with the upgrade of ISS computer components expeditiously. In particular, the replacement of the mass storage device with solid-state memory should be made as soon as possible.
Evidence of Recurrence Control Effectiveness:
NASA concurs with the recommendation. A change request is currently being processed to retro-fit the solid state mass memory into the MDMs. The intent is to make the hardware change prior to flight of the MDMs.
