As a space enthusiast I really enjoyed reading this comprehensively educational article, Brandon. You really know your space stuff! I think it’s not a question of “if” but only “when” humans will land on Mars and begin colonizing the red planet. I would be appreciate your important insights and valuable feedback about who will land humans on Mars first, per an article I wrote here last year about SpaceX vs. NASA https://medium.com/@DBGrinberg/spacex-vs-nasa-can-elon-musk-land-first-humans-on-mars-3f05e07abaff Many thanks. I look forward to reading more from you.
