If the liquid is kept in the shadow it will be at a temperature of zero kelvin (-273 °C). I guess that at this temperature mercury won't evaporate.

- henearkr 6y agoThen on the contrary how do they keep it from freezing?

- henearkr 6y agoIf the phase diagram permits it... They need to find a solid that does not just sublimates when heated in the void.
- kingbirdy 6y agoWon't it still boil due to the near-zero pressure?
- jandrese 6y agoDepends how cold you can keep it. Even if it doesn't boil it could sublimate away if not kept extremely cold.
