We have defeated the gremlins and finally managed to record episode 22, and what an episode it is.

We are joined by Doctor Alice Goreman to discuss a paper she wrote about the problem of preserving our orbital heritage, why we should be thinking about it, and how we might go about the task of preserving our history even as it orbits several thousand miles above our heads.

We also talk about the following stories and papers:
