actually water under a vacuum of .006 atm freezes @ -.01c
From Thermacore:
"Q. Do water heat pipes freeze?
A. Yes, heat pipe working fluids including water maintain the normal freezing point. Properly designed heat pipes, however, will not be damaged by the freezing and thawing of the working fluid. Heat pipes will not operate until the temperature rises above the freezing temperature of the fluid."
