Mars

We never thought a Mars rover could make us get a little teary-eyed, but here we are. It was announced that the well-loved robot Opportunity finally bit the dust on Wednesday after a remarkable almost-15-year run. The scrappy rover lost power during a dust storm last June, prompting NASA's decision to pull the plug on the entire mission. Interestingly, Oppy's twin Spirit passed away in a similar manner on the other side of the planet after a five-year run. 

To aid the grief process, the internet has been meme-ing Opportunity, and we're here for it.
