This week, we welcome Laura Fackrell, geochemist at the University of  Georgia, to the show. We will be discussing her work developing soil for  farms on Mars, capable of growing crops to feed interplanetary  colonists.We will also journey out beyond our solar system, where Voyager 2 hears from NASA for the first time in months. We examine a tiny asteroid  traveling through space along with Mars that is a near-perfect geological match for our Moon. Finally, we will explore the Solar System from our own back yards, as all seven planets visible in the sky can be seen this week from most places on Earth.--- Send in a voice message: https://anchor.fm/the-cosmic-companion/messageSupport this podcast: https://anchor.fm/the-cosmic-companion/support Get full access to The Cosmic Companion at thecosmiccompanion.substack.com/subscribe
