week in t=.pril i961.
3. Thermal Test Set-up
Tea: set-up for thermal tests to be used to empirically design, bafflest
insulation, and conductive shields was completed on 8 Auz ust 1961.
Initial tasLs have been. mado.
4. Spaces Layout
Space layouts and attach fittin locations have been established.
5. Frame Modification
