After 15 incredible years, NASA has bid farewell to the Mars rover Opportunity. I feel like I want to cry. And I can’t stop crying.

“‘My battery is low and it’s getting dark’ is so hauntingly human, so crushingly lonely. I can’t articulate the deep, profound ache that sentence evokes. It’s acceptance and defeat and terror and sadness all at once, all from one tiny machine we asked to explore the stars for us.”

Rest well, Robot. Your work there is done.

“At some point in our species’ future, a human will walk up to the Opportunity rover, clear the dust off her solar array, and wake her up. This probably won’t happen in my lifetime, but it will happen, and when it does, it will be incredible.”
