We went into the optics lab today with the intent for Rick to review the ISS array assembly we unboxed the other day (LHO alog #82731) on which we found some particulate contaminsation and some detached parts.. Rick and Keita are unsure how the support rods (first picture) were bent during transit and they appear to have bent at the top and deformed the cover piece (D1300717) they were attached to as they came unfixed at the other end and so were just resting on the top of the QPD mount plate (D1300719). They appear to have moved around and scored the surface of this platform. Maybe this happened in transit or storage but it seems like it would have had to be a large force and Rick says the storage containers were packed in form during transit.

1st package: Base piece (D1101074-v2 S/N 004) is double-bagged in my office and I have put in a clean and bake order as this spacer is site specific in height and some of our ISS spares will have a spacer set to the L1 beam height instead so we may need to swap it out.

2nd package: Cover piece D1300717 with the spacing posts attached is not bagged properly as we probably do not want to reuse this and so it is in Keita's office.

3rd package: Array and mirror assembly with PDs still attached was wrapped in foil with dry sealed clean room wipes protecting top optic in periscope, then double-bagged. Shown in center left of this image. This will need re-cleaned if we want ot scavenge parts form it.

4th package: All the other parts from assembl y shown in this image ( apart from PD assembly, baseplate, tool pan and top cover) have been packaged up in foil and double bagged in one package. These will also need recleaned if reused.

These last two packages are stored in the cabinet that the spare ISS array units are in, situated in the vacuum bake prep area next to the PCal lab. The shipping cover and base plate for the array are also back in this cupboard.

For reference the assembly drawing can be found here.

The assembly we worked on has the dcc ref S12020967
