demo 2

It turns out Ceres is geologically active with a salty ocean beneath the surface... It's National Science Week and Brad and the team are posing for some satellite selfies.... and Crew-1 delayed again as NASA continues to pour over Demo-2's mission data.

Astronauts Bob Behnken and Doug Hurley are back on Earth following the successful test flight of the Crew Dragon capsule. It means NASA is back in the game of launching astronauts from American soil, for the first time since the shuttle retired almost a decade ago.

It's time for another edition of Talkin' Science with Dr Brad Tucker and Matt Miller.
