Last Minute Instructions From Earth to Shuttle Crew
As we mentioned a week ago, have you ever wonder how the Space Shuttle crews know what they are supposed to do on a moment to moment basis – and how complex tasks are described to the crew? Part of the answer can be seen in the daily “Execute Packages” that are sent up to the Shuttle in orbit from Mission Control in Houston. This graphic is one of many that comprise today’s Execute Package (Download complete document)
Tom, Chris and Dave, Attached you will find the PAS and VE camera tie-down plans.
1. PAS tie-down plan – This plan is basically the same as the one we referenced you to in section 18 but has been updated with site specific details. Reference message 20-0615 (121) for the PAS tie-down plan.

2. VE camera MLI tie-down for launch location – This plan would be implemented after the cribsheet steps have been completed on pg16-3 section V blocks B & D and pg 16-5 section IX blocks B &D. These steps still need to be coordinated with MCC-H prior to proceeding. During the conference we mentioned a tie down plan involving wire ties to recreate the ground path for the MLI. After all the dust settled, that plan is NO GO so we will need to attempt to establish a new grounding path by reinstalling the grounding tab to a bolt (photos of the grounding tabs are below the procedures). Only the upper MLI is required, so we have included steps to remove the lower MLI, install one grounding tab from the upper MLI and use two long wire ties to cinch the MLI around the camera. We believe it will be easier to remove the lower MLI and install wire ties around the MLI than to install two grounding tabs simultaneously. In scenario “a” below, none of the grounding tabs have been released, so both MLI will be left in place. The wire ties used to cinch the MLI will need to be secured to structure as you are installing them to prevent them from floating away should they break sometime in the future. For example, you could wrap it around the microconical or thru the launch lock tether loop (if it is still installed). If the launch lock is left attached to the JEF with no VE, it will also require the installation of the upper MLI, grounding tab, and wire tie to cinch it down. Download complete document
