A walking tour of the solar system Part 1: Mercury to Mars
<p>This week on the Audio Guide to the Galaxy, we're going for a walk. No, really - we're walking through the inner planets of our solar system at 175 000km/s. So put your walking shoes on, and let's head into orbit.</p>
<p>You can listen to this episode any time. Yep, even day time.</p>
<p>Tune in next week for part two, which will take us beyond the asteroid belt to the outer Solar System.</p>
