We have a brand new episode of Professor Blastoff for you this week. You're welcome. It really was very selfless of us. Kyle could have been visiting his mother, Tig could have been raising money for hurricane relief, David could have been drinking cool beers, and Dr. Alex Platt could have been trying on pieces of burnt orange outerwear. But instead they got together and made this podcast about altruism. So once again, you're welcome.
