The Webb telescope success is such a astonishing example of what we humans can do with careful planning and engineering when we try as hard as we can. Also I guess every one of these minute details stems from prior experience, so also a example of how we learn and improve. @NASAWebb/1509244328224432139
To chill to its operating temperature of less than 7 K (-447 F or -266 C), Webb’s MIRI instrument uses a special refrigerator. But it also requires heaters to control its cooldown & prevent ice from forming in space. 🧊
