ITM swap status

(Travis, Betsy, Margot)

This morning, we rearranged the new ITMx (ITM03) monolithic lower structure sections and the now "old" ITMx sections and restowed them for the weekend in the storage container.  We pulled the FC from the CP-front and the ITMx-AR prior to putting the main and reaction chains together.  As planned, this involved swapping out the UIM on the reaction chain such that it matches the UIM on the new main chain.  For the record, we are reusing all OSEMs from the "old" ITMx on the new monolithic one, so testing will be straight forward.

We will be ready to hoist the reassembled monolithic lower structure assembly onto the arm and reinstall it in-chamber on Monday.

 

We also paused to catch a moth that we observed fly into the cleanroom mid-morning.
