This time Dr Becky Smethurst and Izzie Clarke discover why it’s touch and go when it comes to returning asteroid samples to Earth and hear how we’ve been exchanging spit with Mars since the dawn of the Solar System.

The team is joined by Dr Sara Russell, a meteorite researcher at the Natural History Museum in London, and Dr Albert Haldemann, Mars Chief Engineer for the European Space Agency.

As ever, Dr Robert Massey is with us to answer your questions and look ahead to the next month in the night sky.
