Exploring the Solar System

25 September 2013
Presented by Dominic Ford.

Dominic Ford reports from the European Planetary Science Congress, where he heard about the latest misisons to Mars and the Moon. Lewis Dartnell explains how the ExoMars mission, due to land on Mars in 2018, will go about looking for signs of lifeforms that may have died out billions of years ago. Dina Pasini discusses her more speculative ideas about how the life we see on Earth could have started on Mars. And Bernard Foing and Jessica Barnes discuss what we're still learning about the Moon. Plus, we have more answers to your space science questions.
