This is a great podcast and should be much appreciated by everyone and I hope you all are doing good.
Best space science and space policy podcast. And a great organization to support.
Planetary Radio is fascinating, informative, and engaging science journalism at its best. Sarah Al-Ahmed, like her predecessor, delivers in equal parts, enthusiasm, curiosity, and information. Deep gratitude for this contribution to scientific journalism. Keep crushing it, Sarah.
Planetary Radio is the most hopeful, and the most humane, place on the internet. Every episode gives us a chance to feel connected, included, and welcomed, whoever we may be or wherever we may be coming from. Every episode gives us a chance to experience awe. This is what it means to be one human family, headed inexorably Ad Astra. I am so grateful for the weekly reminder of what we can be when we're at our best and doing great things together <3
