@hillexed I am unfortunately not an engineer, so I'm not sure of the details but I know that the wiring is complicated! MIRI & NIRCam are now part of the Integrated Science Instrument Module (ISIM) that sits behind the primary mirror & wires connect the ISIM to other systems like power. Some of those systems are on the warm side of the telescope, so the wires need to be able to take hot and cold temps and the wire materials are CAREFULLY selected to withstand the extremes! #JWST

Guess this is happening. #Introduction time: I'm an astronomer at U. Arizona working on the #NASA #JWST #MIRI and #NIRCam instrument teams studying #galaxies, #galaxyclusters, and #blackholes. Also #hiking, #reading, #videogames, #dogs, #eskies. Current status: progressively panicking as the clock ticks closer and closer to real #JWST data... 😆 #Astronomy #Astrophysics #Science #Space
