Our favourite space rock expert Greg Brennecka joins us to talk about the amazing Hayabusa2 mission, the sample return mission to asteroid Ryugu by Japanese space agency JAXA. Greg and his colleagues have been analysing the sample and some of the findings are incredible.
What does Ryugu tell us about the early solar system? What do we learn about water on bodies like asteroids? and could Ryugu be carrying enough of the building blocks of life to potentially populate another habitable planet?
It's a fascinating chat.

#52 Hundreds of years before GPS there was celestial navigation. Let's see how astronomy and some basic equipment kept old time mariners on course.

Recently, we took a look at GPS and the space science that makes it work. This time, we're going back to an era when navigators had nothing but their equipment and the stars to tell them where they were, even on the open ocean.
Celestial navigation combined the sextant, almanac and chronometer to make a reliable navigation system that just needed one other thing, the sun and the stars... And some handy astronomical knowledge!

#54 NASA’s VERITAS mission to Venus. There’s some good news, there’s some bad news and there’s one incredible discovery hidden for thirty years.

In 2021, NASA announced the VERITAS mission to Venus, NASA’s first voyage to Earth’s twin planet since the early 90’s. Things haven’t gone completely to plan for this project, but one thing VERITAS has already accomplished, it got scientists reviewing data from previous missions, and what they found was truly incredible. And all without leaving the ground.

This is Cosmic Coffee Time, the place where we take a look at what's happening somewhere in the universe in about the time it takes to have a coffee. It's cosmology in a cup. I'm Andrew Prestage, and join me for a coffee and see where in the universe we're going. This time, meteoriticist and friend of Cosmic Coffee time, Greg Brennecka returns to the podcast to talk about the Hayabusa2 mission. It's a fascinating mission that's already prov
