ELON: SOMEONE HAS TO SOLVE ROCKET REUSABILITY — WHETHER IT’S SPACEX OR SOMEONE ELSE “The cost of the fuel and oxygen on a Falcon 9 is 0.3% of the cost of the rocket. So, it's a very tiny number. It's very similar to an airplane. How much does it...

Reminder that nobody from Biden admin publicly congratulated Elon or SpaceX for catching the Starship with giant mechanical arms, representing the critical first step of his multi planetary vision.

@elonmusk We are witnessing the tinkering of Ben Franklin, Thomas Edison, the Wright Bros, and Henry Ford in real time. @elonmusk is generational and @X puts us in the same room.

I love how Elon and the team at SpaceX are relentless in solving rocket reusability no matter how tough the task at hand is it does not make them want to walk away and let another company figure it. SpaceX wouldn’t be where it is today without the relentless pursuit engraved into the culture and with flight 7 on the horizon many learnings will be applied to future flights. Good job to the SpaceX team and Elon.

How would you summarize Elon Musk in one word?

@elonmusk Spending fortunes on disposable rockets is as absurd as throwing away airplanes after each flight.

TARDI's preferred ride is @SpaceX, and we are here since the daw of time and saw all rides.

Here's Elon Musk back in 2010 announcing that SpaceX is going to try to build a fully and rapidly reusable orbit-class rocket. “The pivotal breakthrough that's necessary, that some company has to come up with to make life multiplanetary is a fully and rapidly reusable orbit-class rocket. This is a very difficult thing to do because we live on a planet where that is just barely possible. If gravity were a little lower, it would be easy. If it was a little higher, it would be impossible. Even for an expendable launch vehicle where you don't attempt any recovery, you get maybe 2% to 3% of your liftoff weight to orbit. Now you say, okay, let's make it reusable. Which means you've got to strengthen the stages, you've got to add a lot of weight, a lot of thermal protection, you've got to do a lot of things that add weight to that vehicle and still have a useful payload to orbit. Now, you're saying, of that meager 2% to 3% and maybe if you're really good, get it to 4%, you've got to add all that's necessary to bring the rocket stages back to the launchpad and be able to refly them and still have useful payloads to orbit. So, a very difficult thing. This has been attempted many times in the past and generally what's happened is when people have concluded that success was not one of the possible outcomes then the project's been abandoned. It's just a very tough engineering problem. It wasn't something that I thought I wasn't sure it could be solved, for a while, but then relatively recently, probably in the last 12 months or so, I've come to the conclusion that it can be solved. And I think SpaceX is going to try to do it. We could fail. I'm not saying we're certain of success here, but we're going to try to do it. We have a design that on paper, doing the calculations, doing the simulations, it does work. And now we need to make sure that those simulations and reality agree because generally when they don't, reality wins.” National Press Club, September 29, 2010

Elon Musk in 2008: "NASA was going to pay Russia $70M per astronaut. SpaceX could do it for $15M" Musk is presenting SpaceX to a small audience. He shows a video of the Falcon 9 first stage firing: "This is almost a million pounds of thrust in vacuum, about four times the maximum thrust of a 747. It's pretty much Armageddon down there. You don't want to be standing at the base of that test stand." He explains the NASA contract: "The contract SpaceX has right now is to demonstrate cargo transfer to the space station and return of experiments to Earth. What we're hoping NASA will exercise is an option on that contract to also carry astronauts. I think they will exercise that option fairly soon." On the coming gap in American spaceflight: "The Space Shuttle is retiring in 2010. So unless our spacecraft is active, the US will not have the ability to send people to orbit. For about five or six years, unless SpaceX is successful, there will be no American manned space capability. There'll just be the Russians." He describes the situation bluntly: "The Russians are charging us over $70 million per seat after the shuttle retires. They got us over a barrel and they're doing us hard. We'll spend half a billion dollars per year on the Russians just buying tickets for six or seven astronauts to go to the space station." Musk shares SpaceX's cost: "Our cost per person, even assuming no reusability, assuming every bit of it is expended and no refurbishment, is about $15 million per person. And it's us. The jobs are here. So I think it's kind of a no-brainer. But no-brainers in Washington DC don't always happen." On Congress: "We've been given money for the cargo portion but not for the manned portion. The amount we're asking for to get this done is $300 million. For every year that we're dependent on the Russians, we have to send them half a billion dollars. It seems kind of ludicrous. But anyway, that's DC." Someone asks about the space elevator: "The idea is you have this really long cable, like 40 to 60,000 miles long, with the ends way out in space and the base on Earth. There are a lot of issues with the space elevator. It relies on super strong materials, carbon nanotubes. Until we build, say, a carbon nanotube footbridge, then I think we should not really be thinking too much about building a 60,000-mile elevator. Not this century." On space solar power: "If there's anyone in the world who should love space solar power, it's me. I'm chairman and the largest shareholder of a solar company called SolarCity, and I've got a rocket company. So it should be perfect. Unfortunately, I don't think space solar power makes sense. I wish it did because that'd be awesome. But even if you assume it costs zero to transport the solar panels to space, when you take into account the equipment to convert the energy to microwaves, then equipment on the ground to convert it back to electricity, just that capital cost blows you out of the water. It's not competitive with terrestrial solar power. So there's no point in even thinking about it." On fuel costs: "The fuel and oxidizer cost is really super low. For our big rocket, it's only a couple hundred thousand dollars. For our small rocket, it's about $30,000 or $40,000. If you just look at the propellant cost, it's very, very cheap." On the long-term goal: "One of the design goals for Falcon 9 is that it can go from in the hangar to in the air in under 60 minutes, which would be super fast for a rocket, particularly a big rocket. It's going to take several flights before we get there. But as long as we lay the foundation and make sure the design is capable of that, we can at least have the possibility of getting to a flight an hour in the future."
