The crew spent the morning staging for the next chamber cleaning (BSC-8) while waiting for an overnight shipment of 99.9% isopropanol. The compressor trailer was moved from the LEA to the southwest corner of the LVEA, clean air hose was run to BSC-8, and the air drill assembly area was relocated to the HAM 6 bay.  BSC-7 chamber floor wipe-down was completed but inspection showed some re-deposition and/or re-oxidation on the two mid-sections closest to the door so we will re-install the flooring tomorrow, wipe down upper sections again as required and re-inspect the support tubes for fibers. A cleanroom was moved over the BSC-7 dome in preparation for cleaning.
