How We’ll Live on Mars


The first person to walk on Mars is already alive.

When Neil Armstrong became the first astronaut on the Moon he was 38 years old. Space agencies around the world are planning our first trip to the Red Planet in 30 years’ time. That means the first Martian is at primary school somewhere in the world right now.

When I was working with the British astronaut Tim Peake he told me that “Mars is on for ten year olds”.

This 45 minute talk – packed full of stunning visuals – will inspire you to dream about our future in the solar system.

Rebel Star – The Sun’s Greatest Mysteries 


The Sun is many things: beauty, beacon, battery, belligerent. It’s the biggest thing for light-years around and yet we actually know relatively little about it.

That’s changing thanks to an armada of new spacecraft recently lofted into the solar system to scrutinise the Sun in unprecedented detail. In a 45 minute talk packed full of jaw-dropping images and videos, I’ll be your guide on a journey deep into the heart of our nearest star.

Is time travel possible?

Fancy following in the footsteps of Marty McFly? In this video you’ll discover the story of the greatest time traveller in human history, a man who has done it and lived to tell the tale. You’ll also discover how you likely rely on time travel every day of your life.

Not that it is easy to achieve. You can move through the three dimensions of space in any way you like. But you’re normally restricted to moving one way through time – forwards, at the steady rate of one second per second. It takes a significant effort to travel through time in any meaningful way, but as our technology improves it may become commonplace. 

How to weigh the universe

We’ve never left our solar system and yet we can weigh planets, stars and even galaxies stretching far across the universe. Find out how on this journey through the cosmos, taking in the latest work on exoplanets, gravitational waves, black holes, dark matter and more.

It all hinges on whether the laws of physics are the same out in space as they are here on Earth. Most astronomers believe they are, but a growing number are starting to question it, with profound consequences for the way we think about the universe we live in.


Why Space Matters to Me 


All too often the universe is seen as a remote and distant place that has little to do with our everyday lives. Nothing could be further from the truth. Space affects us all the time, in many different ways. It drives the weather, sends us satellite TV, threatens us with dangers, helps keep track of time and is the ultimate source of all of our food.

Why Space Matters to Me is a 25 minute talk designed to get children to think about their relationship with space anew. Packed full of jaw-dropping visuals, it is also the perfect way to re-enforce the Earth and Space section of the KS2 science syllabus. They’ll never look at the cosmos in quite the same way again.
