Missions on Mars are something you got kind of used to by now. From time to time, some rocket headed to Mars is launched, and this gets in the news for a brief time. At least that’s how most of the people see this. The ones who are more into the field and more curious about the topic know that this is not something we humans casually do. And we don’t do it just for the sake of it. A mission to Mars with the whole package, a rover, and everything, costs about 3 billion dollars. So when we send something to Mars, it’d better bring back something significant.

The mission in preparation right now is called ExoMars, and its rover is planned for launch in 2022.
