...and flights of angels sing thee to thy rest.
After 15 years into its 90 day mission, Opportunity rover is officially put out to pasture.
And, as always, XKCD has the perfect framing for the send-off (link embed wasn't showing properly):
15 years! What an amazing achievement.
The only achievement I can think of in my own life that's lasted 15 years is keeping my 16 year-old cat alive since she was a kitten. Everyone at NASA who was involved in the Opportunity program must feel so proud. And so sad. 😢
