Scientists find evidence of geothermal activity on icy dwarfs Aris and mache,

this week on planetary radio. I'm Sarah Al Ahmed of the Planetary Society, with more of the human adventure across our solar system and beyond.

A team co-led by the Southwest Research Institute has discovered signs of hydrothermal

and metamorphic activity within the icy dwarfs Eris and Machemache in the Kuiper belt.

The lead author on this research, Chris Klein, joins us today to explain.

But first, we have an exciting update from the world of US space politics with our chief of space policy,

Casey Dreyer, and our director of Government Relations, Jack Curly.

We'll also take a moment to celebrate the touch down of the intuitive machines Odysseus

Lunar Lander with our Senior Communications Advisor advisor Matt Kaplan.

Hang out until the end for what's up with Bruce Betts and a new random space fact.
