I really hope this deserves a separate topic: Opportunity has become the first (known...) teenager from an alien planet! Sincere congratulations and huge thanks for teams responsible for MER missions! I remember the day of her landing and regularly check news and images. I do this almost every day. More than 13 years...
In cooperation with Dual Color, a small Polish company which deals with scientific illustrations and animations, and the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw, we made a small gift to celebrate this amazing anniversary. I really hope you enjoy it (you can download the comic in print resolution from here: http://www.dualcolor.pl/en/curiosity-opportunity.html).
Once again: big thanks for people involved in both missions and for all fans here for their amazing passion and skills in processing of images sent by MER rovers.
