Why do we want to go back to the Moon?

Available for over a year

Two plucky spacecraft, one Russian and one Indian, are currently blasting towards the Moon’s South Pole. Both Russia’s Luna-25 and India’s Chandrayaan-3 are due to touch down next week. They’re heading to that particular region of the Moon in order to hunt for water, the presence of which could have huge implications for our further exploration of the Solar System. Victoria Gill talks to Dr Becky Smethurst, an astrophysicist at the University of Oxford, to find out more. Victoria then heads to the Lake District to witness the release of water voles into the ecosystem. Next up, Professor Lewis Griffin, a computer scientist from University College London, tells us how bad we are at distinguishing between real and deepfake voices. He then reveals what implications this might have for scams. Finally, Dr Helen Pilcher tells us all about the intriguing ways that animals can bend time. You can find out more in her book, How Nature Keeps Time. Presenter: Victoria Gill Producer: Hannah Robins Content producer: Alice Lipscombe-Southwell Research: Patrick Hughes Editor: Richard Collings
