Conditions inside craters

Permanently shadowed regions have a stable surface temperature. On the Moon, the temperature hovers somewhere at or below 50 K (−223.2 °C; −369.7 °F). Another temperatures estimate is 25 to 70 K (−248.2 to −203.2 °C; −414.7 to −333.7 °F). The low temperatures make the regions desirable locations for future infrared telescopes.
