The Gemini programme of the mid-sixties is relatively unknown, even though it was an important stepping stone in the Apollo moon programme: Gemini is where NASA learned to fly in space. In this episode we cover Gemini with our two guests David Woods (who has been on the show talking about Apollo) and David Harland. Together they wrote a book on Gemini that serves as the rough outline of this conversation. We talk about the Gemini spacecraft itself, the launch vehicles, some of the achievements and learnings of the programme as well as some of the specifics of some of the missions.

This episode is a conversation with Ruud Hoogeveen from the Netherlands Institute for Space Research about satellite-based Earth observation, and primarily about measuring the concentration of gases such as CO2 or Ozone from space. We talk about the effects of these gases on the atmosphere, how the sensors work in principle, and about the history and evolution of the sensors over the various missions. We conclude with a look on detecting and measuring aerosols and at the future challenges and current research for satellite-based earth observation.
