- dylan604 11mo agoSure, we went through Gemini, Mercury, and Apollo 1-7 before humans orbited the moon. However, we started from blank sheet of paper back then. BO has the knowledge learned from Gemini, Mercury, and all of Apollo to start. I don't need a YT influencer to know my NASA history. I'm old enough it was taught in school while young enough to not have lived through any of it.
- stevenjgarner 11mo agoI am so old I lived through it! - 13 years old staying up all night to watch Neil take his little stroll. Genuine question, how DO they teach it in school? Do they get into the physics of any of it (orbital mechanics, rocketry etc)? Do they get into the cold war geopolitics of it? Do they teach the amazing accomplishments of the Soviet Union as well as NASA?
- dylan604 11mo agoIt's not like it was a class on rocket science, but more of just history of each program being a stepping stone towards the ultimate goal of landing on the moon
- JumpCrisscross 11mo ago> Check out the Smarter Every Day NASA talk FYI, that talk was poorly received in the aerospace community. Destin missed that the entire point of Artemis is not to one and done the Moon again but build towards getting to Mars. And the repeated "we're going, right?" shtick was condescending in the same way Hegseth wanting generals to cheer and holler for him was. He acted like a petulant influencer. Not a science communicator.
- bryanlarsen 11mo agoAFAICT it's "getting to Mars" for SpaceX and their ecosystem, and "sustainable cislunar economy" for Nasa, ULA and Blue Origin and their respective ecosystem. For example, see ULA's "cislunar 1000" concept from ~10 years ago. Either way, your criticism of Destin's presentation hits. One and done'ing the Moon is not particularly helpful in setting up a sustainable cislunar economy.
- JumpCrisscross 11mo ago> it's "getting to Mars" for SpaceX and their ecosystem, and "sustainable cislunar economy" for Nasa, ULA and Blue Origin and their respective ecosystem In 2017 Space Policy Directive 1 amended the national space policy to pursue "the return of humans to the Moon for long-term exploration and utilization, followed by human missions to Mars and other destinations" [1]. This formally established the Artemis program [2]. Destin's criticisms were apt for Constellation [3], which was closer to an Apollo reboot. They were uninformed for Artemis.

- brain_staple 11mo agoThat was my interpretation of that talk. It seemed like a regurgitation of opinions of an old aerospace engineer. But that's probably unfair to Dustin, I believe that he actually came to that conclusion himself. But it was a really incorrect take that SLS was somehow the "safe bet" in comparison to betting on Starship. The whole talk just seemed insane based on what I knew about both programs.
- imtringued 11mo agoThe payload capacity of Starship version 2 is around 35 tons to LEO. The propellant capacity is 1500 tons. This means it takes 42 tanker loads to fill up one Starship. This means Destin was extremely optimistic with respect to how well Starship is going to perform. Even with the projected 100 ton payload for V3, the minimum number of flights to refuel a V2 HLS Starship is 15 flights and 26 flights for V3 HLS. If we are optimistic about New Glenn and the cislunar transporter, then it will take 4 flights to refuel the transporter for each moon landing plus one flight to launch Orion on New Glenn and another three flights to push Orion using the cislunar transporter. There is also a hypothetical option to use a second Blue Moon MK2 between LEO and NRHO plus a crew capsule launch that says in LEO. Given a budget of 4 billion USD, this could pay for 50 New Glenn flights assuming falcon 9 pricing. 8 flights per moon landing means one moon landing every two months. That seems pretty promising unlike SpaceX, which is locked entirely behind a functioning reusable second stage or they don't get to participate at all, because expending 15 to 26 upper stages is not viable at all. But you do you. SLS only has to launch a few times until the cislunar transporter gets established, which means it is exactly the safe bet that the US needs to reach the moon.
