Izzie and Dr Becky are flying closer to home to look at the Rocky Planets; Mercury, Venus, Earth and Mars. How are they different? How are they similar? And can understanding their past tell us anything about Earth’s future? Plus, Dr Robert Massey has his stargazing tips for summer.

With special thanks to Dr Suzie Imber from the University of Leicester, and Sian Prosser from the Royal Astronomical Society.
