The latest series of the ABC Radio National podcast #CosmicVertigo is out and we're taking things to the EXTREME. I have to say I have the most fun with Dr Amanda Bauer recording these, they're made for your listening pleasure so I hope you enjoy it as much as I do... subscribe where you get your podcasts. Rate and review etc.

However this time you can also ask us questions online or by email (especially if you record them!) and we'll feature the best (or at least the ones I can answer) on the show. Enjoy!

At the truly epic World Government Summit I was privileged to lead the discussion of Mars settlement by the best and brightest from the UAE Space Agency and make the broader case for space with an international panel. Apart from that I got to hear from Forest Whitaker, Neil DeGrasse Tyson and Michio Kaku all in one day..! The #worldgovsummit is truly an extraordinary meeting of the world’s best minds. Just as exciting will be to see the new businesses and activities that come from this meeting, I certainly aim to work more closely with an international range of impressive people, all with varied backgrounds I could never hope to have met at any other meeting. It was a genuine pleasure to meet and discuss space technologies with the extraordinary young engineers of the Mohammed bin Rashid Space Centre. I have to say the task facing the program director for Mars 2117, Saeed Al GerGawi, are humbling - but he and his team are more than up to the task if this gorgeous VR tour of their Mars City is anything to go by!

This is an incredible honour and something I'm delighted to finally announce but after a national application process I've been chosen as the new Lead Scientist of the Royal Institution of Australia, home of Australia's Science Channel. 

Australia, and the world, faces significant challenges ahead but it will be more science and technology not less that will see us through. That’s why it’s so critical we continue to explain and share the latest breakthroughs by Australia’s researchers and inspire the next generation into STEM. At Australia’s Science Channel we can ensure the best and most inspiring science stories are fed directly into classrooms around the nation, and further shared around the world. 

I hope I live up to the great legacy of the Royal Institution and am able to play a positive role in raising science's profile, and science literacy more generally, in Australia!

It's hard to put into words how significant Prof Stephen Hawking was for me on a personal level. His book "A Brief History of Time" was a defining moment as a young teenager to realise that you could have a career to explore the Universe; to spend a life studying the nature of expanding universes, blackholes and dark matter. More important than even his science he also showed the value of communicating that science. 

His death hit me hard and it was a crazy day speaking on radio, TV and print to explain just why he was such an incredible and unique figure. I've shared a few of these TV interviews below. The first TV interview I ever gave was about him, and I was honoured that I could also speak at the end.

The Australian Space Agency review is to be released in a matter of days but do you know what it means for you, your children's future careers or even how much you already use space in your everyday life? Well with the team at The Royal Institution of Australia we put together a package answering all of these issues on Australia's Space Future. I'm really proud of the team's exhaustive efforts and also amazed by the careers of talented female scientists and engineers like Andrea Boyd, Flavia Nardini and Lisa Stojanovski who we were able to feature. In space our future really is unlimited.
