00:00 Going to the moon is an adventure in itself.
00:02 And certainly exploiting the ice there, because with ice you've got oxygen to breathe and water to drink.
00:08 It's a valuable resource.
00:10 So going to the moon is value in itself, but there's ice on Mars.
00:15 So what you learn on the moon in building a base up and exploiting the ice and using it,
00:21 you can actually take and use that technology on Mars.
00:24 So you're practicing for a Mars base.
00:26 The problem is that the moon is three days away, and it's relatively straightforward to get there.
00:31 Mars, the voyage, is the big frontier, because it will take the best part of a year to get there.
00:36 We do not know how to keep people alive in deep space on such a long voyage.
00:41 That is something that's going to take 15, 20 years to actually come to terms.
00:47 We're not going to see the first people going to Mars until the 2040s,
00:50 but we will see a base on the moon in six or seven years' time.
