Ceramic conductor blocks ITD0053 and ITD0054 were replaced on TM2. Initially, only ITD0053 was to be replaced but after removing it it was noticed that
ITD0054 (the larger conductor block behind it) was also broken, fractured through the helicoil that retained ITD0053 (see attached picture).
Both the old 53 and 54 fell into multiple pieces upon removal (see attached photo).

Entry  Friday, January 11, 2019, 13:59, Isaac Earle, Safe Module Parking, Development, , , SMP motor selection decision 
SMP drivetrain design work is currently underway.  Alejandro has selected a suitable 1200:1 reducer which will give a vessel rotation speed of 0.21rpm
with a 1725rpm motor (deemed sufficiently close to the SHC rotation speed of 0.17rpm).  The reducer however is only rated for 0.33hp, and Allon's
analysis recommended we use a motor of at least 0.4hp
