Any talk of Curiosity gets me thinking about Opportunity as well (the Spirit rover lost contact back in 2011).
Sure enough, plucky Opportunity is still exploring and doing science on Mars, more than 12 years after its arrival. What a glorious age we live in, that there are multiple Human-made robots roaming around Mars.
So far I’ve spotted no fewer than 12 humanoid faces and figures.
More amazing proof of ancient civilizations on Mars: Notice how the names of Martian landforms are similar to many on Earth. Does NASA expect us to believe that’s coincidence?
