Research Testing Conclusion<br />

• Well over 1000 cryogenic thermal performance<br />

tests of over 100 different thermal insulation<br />

systems have been produced by the<br />

CryoTestLab at NASA Kennedy Space Center<br />

• Specific insulation systems must be optimized<br />

for best performance (such as lowest k-value<br />

and bulk density) under different vacuum levels<br />

• All modes of heat transfer (radiation, solid<br />

conduction, gas conduction, and convection)<br />

must be addressed<br />
