It’s strange to feel sadness for what is, strictly speaking, not very different from a refrigerator or any other appliance. And yet, following Cassini’s descent into Saturn and its ultimate demise has indeed made me sad. I know there will be more missions (and even better machines that will send sharper pictures), but I will definitely miss knowing this cool little probe is out there gathering photos and information for us so that we may understand our solar system (and our Universe) better.
