Our reporting about farming, AI and satellites turned into three episodes of this podcast, which you can find linked here in the show notes, and as part of this reporting we also toured a satellite factory in downtown San Francisco, called Planet Labs. This week we bring you along for one of our audio postcards to hear how these satellites are built and tested. We meet:  Jacob Stern, director of test engineering at Planet Labs Credits: This episode was produced by Jennifer Strong with help from Anthony Green and Emma Cillekens. It was edited by Mat Honan and mixed by Garret Lang, with original music from Garret Lang and Jacob Gorski. Art direction by Stephanie Arnett.
