The Thermal Design of a Spacecraft to Survive Deep Space
Quick fact
In deep space, an unprotected object can swing from over 150°C in direct sunlight to below -150°C in shadow, yet a well-designed spacecraft maintains its internal components within a comfy 20°C range using only clever geometry and surface coatings.
Why this is interesting
You've seen astronauts in space — but have you ever wondered how a spacecraft keeps from freezing in the darkness of deep space while being roasted by the Sun on the other side?
