- Ad Astra for Real
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

But that doesn’t stop this podcast from begging for more donations from regular people. Somehow the rich keep getting richer while the rest of us keep getting screwed.
