Did you know that space is dusty? James Stubbing is an astrochemistry PhD student who studies interstellar dust, and surface processes that are relevant to space. His laboratory has a chamber that creates the conditions of space, at low temperatures and a trillionth of atmospheric pressure. Here he watches how particles bind to a graphite surface, giving us clues about catalysis, how life may have formed, and how it may form in the future.

We talk about interstellar dust and what it's made of, space tourism, and how we're all made of star-stuff. James tells us a Space Newsflash, and we compare hilarious/distressing lab incidents.
