Astronomy Cast Ep. 752: Should We Go to the Moon or Mars Next? By Fraser Cain & Dr. Pamela Gay Streamed live on Apr 16, 2025. Hosted by: Fraser Cain and Dr. Pamela L. Gay There is an ongoing debate on where NASA should go next with humans: to the Moon or Mars. (Or maybe an asteroid or one of Mars’ moons). We are on the verge of sending humans back to the Moon. At the same time others would prefer we focus our exploration on Mars. It’s a tough choice because there are costs and benefits to both. Let’s try to give this conversation some nuance. Let's discuss the reasons for each of these worlds. SUPPORTED BY YOU! This Episode is made possible thanks to our Patrons on Patreon.
