Heat shields are one of the trickiest problems left to solve before we can have truly reusable spacecraft. So far we've seen different solutions, like ablative materials or ceramic tiles. But can a sweating heat shield be a solution? Finding out in this interview. 🟣 Guest: Dr. Hassan Saad Ifti http

What makes me so pessimistic about humanity's progress? From which kilonova did our heavy elements originate? What's the situation with dark stars? And during our free Q&A+ on Patreon, is it feasible for a single nation to establish a Moon outpost? I'll address all these questions and more in this e

What's the current state of development of artificial gravity with spinning space stations? Do I trust SpaceX to get us to Mars? Will China be the first to get there? And in the free edition of [Q&A+] on Patreon, why won't NASA just launch upgraded versions of Voyagers? Answering all these questions

Will astronauts be eventually replaced by robots in space? Is there a plan for a replacement for the Kepler telescope? Do Intuitive Machines failures mean that Starship HLS is kind of in danger? And in our free bonus question on Patreon, will Artemis become 100% SpaceX? All this and more in this Q&A

Space Docks are everywhere in science fiction. It's the most logical way to build big constructions in space. So, NASA funded a futuristic project that studies the possibility of assembling structures in space. Watch the video here (with no ads) or on YouTube: https://youtu.be/3BHNz68krNM

What will happen to Phobos and Deimos in Mars' orbit? What happens to different body parts in space? Could Venus be a better destination for human exploration than Mars? Answering all these questions and more in this Q&A show. Watch the video here (with no ads) or on YouTube: https://youtu.be/-2C3va

Before my interview with Eric Berger, I asked you to send me any questions you might have. Caerdwyn asked: As a high-profile space journalist, what trends are you seeing with regard to the quality and focus of space journalism? i.e. trends in factuality, optimism/pessimism about specific projects or

Will SpaceX be able to deliver Starship in time for Artemis? Will Elon and Donald cancel SLS and replace it with Falcon Heavy? Is there any chance for real competition with SpaceX? How serious is the space race with China? Finding out the answers in this interview. Watch the video here (with no ads)

Polaris Dawn launches and completes the first private spacewalk, the surface of a giant star is resolved with incredible detail, Starliner comes home empty, and amazing new images of Mercury from BepiColumbo. Watch the video here (with no ads) or on YouTube: https://youtu.be/gwWYzlXOIsw

Self-replicating space robots seems as an obvious way to explore the Universe. How close are we to such a scenario and what do we need to fill outer space with Von Neumann probes? Figuring out with Professor Alex Ellery. Watch the video here (with no ads) or on YouTube: https://youtu.be/vo863_0SI_o

Solar sails aren't just a tool to send tiny spacecraft to Alpha Centauri. They can also be used to optimize exploration of the Solar System. How can we do that? Figuring it out with Alexander Alvara.

Can dark energy be just empty space and nothing else? Is there a new space race going on? Why is NASA so slow with its Moon plans? Is there an upper limit for a star? Answering all these questions and more in this week's Q&A. Watch the video here (with no ads) or on YouTube: https://youtu.be/D6y0xNG

In this week's Q&A show, I answer questions about Starship might be able to provide artificial gravity, whether I'd prefer to have LUVOIR or the Overwhelmingly Large Telescope, and if nuclear-powered rockets will work in space. You can join me live every Monday on my YouTube channel at 5pm Pacific T

In this week's questions show, astronaut Mike Massimino answers a question about astronaut training, I wonder how we could survive if the Sun dies, and explain why the shuttle's fuel tank was first white and then changed to orange.
