Hello and welcome to Six Minute English, I'm Neil.
And hello, I'm Rob.
So, Rob, you are a man who enjoys travel.
What's the furthest journey you've ever made?
Well, I have been to the other side of the world.
I've been to Australia, New Zealand.
So, from London, that's a very long way.
And how was it?
Well, it was pretty boring, really, and quite cramped on the aeroplane.
But I loved it when I got there.
So, how would you feel about a journey of 56 million kilometres that took around nine months?
Oh, right.
I'd have to travel business class, I think.
Lots of movies and a very comfortable seat.
Well, that's how long it would take to get to the planet Mars.
And this programme is all about the women who want to be the first to set foot on the red planet.
First, though, today's question,
which is about the size of Mars.
