Artemis II Splashes Down: Nikon D5 and Z9 Shot the Moon

NASA didn't take the latest mirrorless flagship to the moon — they took a D5, and it's worth asking why. The answer is a quiet rebuke to the 'always upgrade' culture: proven radiation hardness and high-ISO performance that still holds up where no repair shop exists. For working photographers, the real story is the Z9 hitching a ride as a radiation guinea pig — NASA's already planning for Artemis III, and the data from that sensor in deep space will tell us more about stacked-sensor durability than any lab test ever could.
