Redundancies, 7-time Flown Falcon 9, & the Reusability Equation | Today In Space #224

This week Alex talks about the 3D printing fire that was prevented due to redundancies, geeks out about the space shuttle, and then discusses the latest success from SpaceX with their 7th time flown Falcon 9 B1049. This kind of progress in space brings about a new era we're watching unfold in real time. To answer last weeks question about how much money rocket customers are saving by using a reused Falcon 9 - we did some research to figure out what the numbers really are and how SpaceX is making money with reusable first stage rockets.  Finally, we discuss the second 15KM hop of the Starship SN8 prototype and I did some math to try and illuminate just how tall 15kilometers really is.... (CORRECTION added for cruising altitude comparison. I had my math wrong - thanks for catching that Ku5i on Youtube!) https://www.nasa.gov/mission_pages/station/research/news/spacex-crew-1-science-iss https://www.elonx.net/how-much-does-it-cost-to-launch-a-reused-falcon-9-elon-musk-explains-why-reusability-is-worth-it/ https://www.inverse.com/innovation/spacex-elon-musk-falcon-9-economics
