Kevin Yates from the National Space Centre joins us to talk about a brand new gallery all about satellite data on Earth! 

In Science in the News we hear about a lucky 6 year old fossil hunter who found a 20 million year old shark tooth, and a fireball that was spotted over the UK! 

We answer your questions, this week we find out how we could survive on Mars, and how our eyes process colour! 

We also catch up with Professor Hallux and Nurse Nanobot in their Map of Medicine series, and today we're talking allergies. In our new Deep Space High Series we learn all about lightning storms!
