68 – The Case of the Inexplicable Oxygen (feat. Melissa Trainer)

Play Episode (43:48)

For years, the NASA Curiosity Rover has been quietly sniffing the atmosphere in Gale Crater with its SAM instrument. Today, scientists are finally getting a handle on that vast dataset, and they’re turning up some crazy results, especially an unexplained oxygen spike! Dr. Melissa Trainer from NASA Goddard, lead author on a paper covering the results, joins Jake to talk about this peculiar behaviour.

We talk Oxygen, Curiosity, and Atmospheres

An Exciting Space Future

WeMartians is celebrating its fourth anniversary this month, and I couldn’t be more happy with the way this project has turned out. What began as a hobby has transformed in to a thriving community of thousands interested in Mars exploration.

I’ve got what feels like hundreds of ideas to make this show better, but I’ve always struggled balancing this hobby with my day job and the rest of my life. There’s not much else I can do without somehow getting more time! And so I’ve made some decisions to do just that.

I’ve left my day job. WeMartians is officially on the path of #GoingPro.

Learn more about the decision, what it means for the show, and how you can help at our blog post explainer!
