Can we make the Van Allen belts safe to fly through? Why not get a super gravity assist from the Sun? Can we predict the next supernova in the Milky Way? And in our extended Q&A+ version, what's going on with the ocean rocks producing electricity at the bottom? Answering all these questions and more in this Q&A show.

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.

Can we refuel James Webb at L2 when it runs out of propellant? What will the Dragonfly octocopter see on the surface of Titan? Will discovering life on Mars stop us from going there? And in our extended Q&A+ on Patreon, what are space things I'm hoping to see in my lifetime? Answering all these questions and more in this Q&A show.

Terraforming Mars is usually considered in the realm of science fiction. But actually we have technology to start doing it in our lifetime and achieve some meaningful results it a timescale of tens of years, not thousands. What are they? Finding out in this interview.

May 22nd, 2025
When did humans first think of aliens? Why is Oort cloud a sphere when the Solar System is a disk? Which space image is my favourite? And in our Q&A+ on patreon, is search for life only limited to looking for water? Answering all these questions and more in this Q&A show.

May 20th, 2025
Which space mission would I save from cancellation if I could? Is fighting space junk with lasers a good idea or not? What if we find asteroids that have already been mined? And in our Q&A+ on patreon, how do we measure masses of black holes ? Answering all these questions and more in this Q&A show.

So far we couldn't find liquid water on Mars. But there are still places where it can hide from us. One of them is pockets under the ice. How can it exist there and which possible ways do we have to detect it? Finding out in this interview.

May 16th, 2025
ESA’s PLATO mission gets its eyes installed, Webb finds water ice in another star system, could it be dark matter and not dark energy that’s evolving over time? And in our longer [Space Bites+] on Patreon, researchers have found that hardy bacteria are evolving to thrive in spacecraft clean rooms.

Our current tech doesn't allow us to block light from Sun-like stars to see Earth-like planets. The brightness difference is just too high. One of the ways we can achieve it is with quantum coronagraphs. What are they and how do they work? Finding out in this interview.
-
May 14th, 2025
Why risk sending big space missions instead of swarms of cubesats? Can NASA protect future Mars astronauts from radiation with EM-rockets? How close are we to discovering our first exomoon? And in our Q&A+ version, which sci-fi tech is the closest to becoming a reality? Answering all that and more in this Q&A show.

The Kerbal Space Program is a fun game, but also an incredible tool for simulating a realistic space exploration program. According to a new paper, people playing the game can help develop innovative ideas that can turn into real missions, especially with the development and integration of reusable rockets like Starship and New Glenn.
