Ancient Tools, Life On Mars, An Aurora Named Steve. March 16, 2018, Part 2.

Scientists have been trying for a long time to piece together a question: When did traits of modern humans—like complex thinking and behaviors—first develop? Anthropologists have uncovered tools in Kenya that date to 280,000 years ago that contained non-local materials, indicating that early humans developed social networks and advanced technology tens of thousands of years earlier than previously thought. What would daily life be like on the Red Planet? We called a couple experts from NASA, MIT, and Georgia Tech to find out. From meals to transportation, we imagine life on Mars.  Finally, how do you solve a puzzle like Steve? That was the name given to a mysterious southerly pink streak in the aurora borealis, after aurora enthusiasts using the citizen science platform Aurorasaurus began to notice the streak appearing again and again in the images they were sharing.  Subscribe to this podcast.
