We have learned a lot about the red planet, thanks to the data and images captured by these missions. We couldn’t positively identify the existence of life on Mars.

But we did find some interesting photographs that piqued the public interest in Mars exploration. Let us take a look at a few.

Little Colonsay was a shiny object on the Martian surface discovered by the Curiosity rover. Scientists think it could be a meteorite, but they’re open to other possibilities.

Forget about crop circles. There was an interesting image captured by the Mars Reconnaissance Orbiter (MRO) in February 2016. It shows a peculiar pattern on the surface of the red planet that looks a lot like the dots and dashes of Morse code. 

It is, in fact, made of dunes.

Scientists have attempted to analyze this code, which translates to a seemingly gibberish line, "NEE NED ZB 6TNN DEIBEDH SIEFI EBEEE SSIEI ESEE SEEE !!"
