LaserSETI would like the sympathize with all of the humans experiencing a heat wave today.
We spent a long time refining the thermal protection system for the instruments. Internal circulation, special heat-shedding paint, multiple exhaust fans, sunshades with embedded mirrors to reject even more heat. Days like today prove the value of that investment.
It’s 44 C (112 F) right now at Ferguson Observatory (RFO) and the cameras are the hottest I’ve ever seen them: 61 C (142 F)!
For comparison, the cameras on top of Haleakala, Maui (IFA) are a cool 16 C (61 F) right now.
