In this episode, Chris Johnson from the Secure World Foundation joins me to do a deep dive on the curious news about an Israeli spacecraft crash landing onto the moon, and potentially releasing thousands of little critters called tardigrades onto the lunar surface. We ask such important questions as 'what is a tardigrade?', explore the ins and outs of international planetary protection laws, and explain why, even though it's highly unlikely the tardigrades will ever manage to colonise the moon, this case still matters.

More information can be found in the series of essays published by Chris Johnson, Dan Porras, and others in The Space Review.
