Quiz: How much do you know about the planet Mars?

Test your knowledge.

EARLIER THIS WEEK, Nasa’s Mars Perseverance rover landed on the red planet to begin its search for traces of life. 

The mission is to explore and collect samples for future return to Earth from diverse ancient environments on Mars.

Over the course of several years, it will attempt to collect 30 rock and soil samples in sealed tubes, to be eventually sent back to Earth sometime in the 2030s for lab analysis.

So, let’s see how much you know about the red planet…

    @Steve Smith: Yes, eating chocolate bars doesn’t make you know who invented them. But I didn’t always understand this, I remember telling my parents I didn’t understand why the kid who lived right next to the school wasn’t a genius, like information should leak out of the school and into his brain.
