Spirit

Image text: On January 26th, 2213 days into its mission, NASA declared Spirit a 'stationary research station', expected to operational for several more months until the dust buildup on its solar panels forces a final shutdown.
The title of the comic is a pun on the word "Spirit" because the name of the Rover is Spirit and in the comic, the rover is showing almost unwavering spirit as it goes about its mission for six years.

I believe technically the Smithsonian now owns the Viking landers from the 1970s, all they have to do is collect them

It’s also important to note that both rovers on the mars surface were expected to last 90 days because of dust building up on the solar pannels but both far exceeded that period (because of marsian sandstorms). Both experienced casualties during that time and one (apparently the one in the comic) got irreversibly stuck.
