Episode notes

SpaceX is coming up on 100 consecutive landings of an orbital class rocket that's, you know, 45 meters tall, 3.7 meters wide. So seeing the success of that, I think people are now more like, well, okay, maybe, maybe there is actually the opportunity to be fully reasonable. That's definitely probably the biggest constraint that I think has been questioned. The idea of going to Mars is absolutely reasonable.
