Issues
LAT F2F Meeting
17 Mar 2005
Use of QUAL flight TEM/TPS for FM116 or FM117 environmental
testing at NRL.
 Need next week for safe to mate for FM116 or week later for FM117

Restarting TVAC at NRL on 3/21 but without checkout of “Big
Blue” Thermal Control System
 Not needed for CAL testing – individual cold plates for each CAL and
TEM/TPS.
 “Big Blue” TCS will be checked out between CAL tests.
 Next CAL TVAC will be FM111 – FM114

Need to re-install (rent) humidity control system (dehumidification)
for work in May and June
 Approx $25K cost expected to be covered within existing budget.
