Who will get sample from Mars first? Who controls the James Webb Space Telescope? Does space radiation rule out panspermia? Answering all these questions and more in this Q&A show.

We all want to see potentially habitable exoplanets around Sun-like stars. But to do that you need a starshade. Something to cover the star and reveal the faint planets around it. What can we build these structures from to make them rigid and strong enough? Finding out in this interview.🟣 Guest: Christine GreggDynamically Stable Large Space Structures via Architected Metamaterialshttps://www.nasa.gov/directorates/stmd/niac/dynamically-stable-large-space-structures-via-architected-metamaterials/

Why are most craters circular, no matter which angle the meteor falls? Is there a size limit for a telescope before diminishing returns take place? Can black holes have atmospheres? Answering all these questions and more in this Q&A show.

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.🟣 Guest: Dr Vojtech Holubhttps://thinkorbital.com/

The MOXIE experiment on the Perseverance rover showed that creating oxygen on other planets is possible. Now, we can apply the same logic to Venus. This could allow the creation of constantly floating balloons, leading to cloud cities in the future.

Venus is closer than Mars. It's more Earth-like. We can bring back samples from it. But it's chronically underexlored. This is why we need a Venus Exploration Program!🟣 Guest: Dr Paul Byrnehttps://arxiv.org/pdf/2412.06830

The building blocks of life have been found in asteroid samples, the most volcanic activity ever seen on Io, astronauts are searching for bacteria on the outside of the space station, and Ingenuity found surprisingly fast wind speeds on Mars.

How big can a space crowbar be? Why does the Sun look bigger near the horizon? How do we measure temperature on the Moon? Answering all these questions and more in this Q&A show.

NASA is launching a new telescope this year called Pandora. It'll be specifically inspecting atmospheres of exoplanets. It even uses spare parts from JWST. Learning more about the Pandora telescope in this interview.🟣 Guest: Dr Ben Hordhttps://pandorasat.com/

Did we find ore veins on Moon or Mars? Can we see astronomical objects in 3D? Can we catch a ride on a comet? How will the internet work on Mars? Answering all these questions and more in this Q&A.
