Instant Genius is a bite-sized masterclass in podcast form. In this episode, we're joined by astronomer and author Dr Stu Clark to explore how our image of Mars has evolved over the last 150 years.

And there's a particular reason for this: this week the Red Planet comes into opposition, providing you with an excellent chance to study Mars from Earth.
