Mars on Earth. That's where this week's guest has been and she joins us to talk all about it. Sally ventured to Antartica this year, prompted by her deep concern for sea-level rise, having lived her whole life by the water. She got to see a lot of cold, blue water, icebergs, penguins and seals on her epic voyage across the Roaring Forties with 350 other intrepid travellers and scientists down to an icy rock twice the size of Australia. We learn about her packing kit, the Zodiac, the ship and the view out the window. What about that view! Thank-you so much for joining us to share your amazing journey, Sally, and keep up your care for our wonderous planet.
