On May 29, 2025, Elon Musk delivered his company speech at Starbase, Texas, the newly incorporated city and SpaceX’s hub for space travel to Mars. This transcript, which I have worked hard on to bring you accuracy, captures Elon’s valuable and historical words.
Elon details Starbase’s evolution from a sandbar to a powerhouse for building the world’s largest rockets. Elon highlights breakthroughs like rapidly reusable rockets, Raptor 3 engine, and orbital propellant transfer plans, all critical for a self-sustaining Mars civilization. With vivid descriptions of catching boosters with “giant chopsticks” and plans for a million-ton Mars transfer, our hero Elon inspires a future where anyone can visit Starbase or journey to Mars.
Elon Musk: The gateway to Mars. Here we are at the newly incorporated Starbase, Texas. This is the first new city made in America in, I think, quite a few decades. At least that’s what I’m told. It’s a very cool name, named because it’s where we’re going to develop the technology necessary to take humanity, civilization, and life as we know it to another planet for the first time in the 4.5 billion-year history of Earth.
[Lots of cheering. Elon shows a short video of the history of Starbase. He talks along with the images.]
Elon: We started with basically nothing. Starbase started as a sandbar with nothing.
[The video shows a prototype rocket and two open tents.]
Elon: Even those little things we built. That’s the original Mad Max rocket!
[Looking at the rocket from 2019, six years ago, the camera pans around it. The sun hits the side, revealing a gorgeous, surreal piece of steel.]
Elon: You know, lighting is very important for that Mad Max rocket.
[Elon is smiling, with his hand in a determined fist. He’s not afraid of silence; this is a tribute to that incredible rocket. Many employees in the audience may not have seen it in person; it’s six years old. Some may have been in high school at the time.]
Elon: Not long ago, there was basically nothing here. In about five or six years, thanks to the incredible work of the SpaceX team, we’ve built a small city. We built two gigantic launchpads and a gigantic rocket factory for a gigantic rocket. The cool thing is, anyone watching can come visit because our entire production facility and launch site are on a public highway. Anyone in South Texas can see the rocket up close, see the factory, and anyone interested in the largest flying object on Earth can drive down the public highway and see it! Pretty cool!
[Video progresses to Starbase 2025.]
Elon: We’re now at the point where we can produce a ship roughly every two or three weeks. We don’t always produce a ship every two or three weeks because we’re making design upgrades, but ultimately we’re aiming for the ability to produce 1,000 ships a year, so three ships a day.
[On the video, birds chirp, water glistens, and a hovercraft pulls gently away from Starbase Beach.]
Elon (smiling): That’s our hovercraft. We’re driving the booster down the road to the launch site. You see the Megabays. The cool thing for those watching is you can literally come here, drive down the road, and see it. This is the first time in history that’s been possible. That highway on the left is public. You can just come and see it, which I recommend. It’s very inspiring.
[Elon points to a render of a massive building.]
Elon: There’s a person next to it that looks like a tiny ant. That’s our Giga Bay! We’re expanding integration to produce 1,000 per year. The Giga Bay hasn’t been built yet, but we’re building it. It’s a truly enormous structure, one of the biggest in the world by some measures, designed for 1,000 Starships per year. We’re also building a Giga Bay in Florida, so we’ll have two facilities—one in Texas and one in Florida. It’s difficult to gauge the size of these buildings because you need a human for scale. When you see how tiny a human is next to it, you realize how enormous it is.
BUILD COMPARISON
Elon: When we look at our build comparison in vehicles per year, Boeing and Airbus make airplanes, but Starship will probably make as many Starships for Mars as Boeing and Airbus make commercial airplanes. This is an enormous scale, and each Starship is bigger than a 747 or an A380. In terms of Starlink satellites, version three satellites, we’ll make on the order of 5,000 per year, and at some point, closer to 10,000 per year. Those Starlink V3 satellites are roughly the size of a 737 (unfurled). They compare to the B-24 bomber in World War II. The scale of production is still small compared to Tesla.
[A large chart appears, showing Tesla’s massively scaled production: currently 1,773,443 cars per year.]
Elon: Tesla will probably double or triple that volume in the future. It puts things into perspective that it’s possible to build a vast number of interplanetary Starships. Even when comparing tonnage, Tesla and other car companies produce far more complex manufactured tonnage than SpaceX, showing it’s achievable. These numbers, while insanely high by traditional space standards, are achievable because they’ve been achieved in other industries.
Progress is measured by the timeline to establishing a self-sustaining civilization on Mars.
Elon: With each launch, especially early on, we learn more about what’s needed to make life multiplanetary and improve Starship to take hundreds of thousands, if not millions, to Mars. Ideally, we can take anyone who wants to go and bring all equipment necessary to make Mars self-sustaining, so Mars can grow by itself. Worst-case scenario, we reach the point where Mars can continue to grow even if supply ships from Earth stop for any reason. At that point, we’ve achieved civilization resilience, where Mars could rescue Earth or vice versa. Having two self-sustaining planets is incredibly important for long-term survival. A multi-planet civilization is likely to last ten times longer than a single-planet one because of risks like World War III, meteors, or supervolcanoes. With two planets, we keep going, then move beyond Mars to the asteroid belt, Jupiter’s moons, and other star systems, making science fiction reality. To achieve this, we need rapidly reusable rockets to keep the cost per ton to Mars as low as possible. That’s essential. We need rapidly reliable rockets—it’s like a pirate’s “Rrrr”: rapidly reusable, reliable rockets!
Congrats to the SpaceX team on catching the giant rocket.
Elon: It’s mind-blowing that the SpaceX team has caught the largest flying object ever made multiple times using a novel method of catching it with giant chopsticks!
[SpaceX employees and Elon pause to watch a video showing the booster, with fiery engines, descending through space, adjusting, and being caught with chopsticks.]
Elon: Have you ever seen that before?
[The video is awe-inspiring. Elon congratulates his team, calling it quite an achievement. Everyone cheers; it’s an emotional moment.]
Elon: We catch it this way, which has never been done before, to make the rocket rapidly reusable. If the super heavy booster, 30 feet in diameter, landed with legs on a pad, we’d have to pick it up, stow the legs, and move it back to the launch pad, which is difficult. But catching it with the same tower that places it in the launch mount is the best for rapid reuse. It’s caught by the arms that placed it, then set back in the launch ring immediately. In principle, the super heavy booster can be reflown within an hour of landing. It returns in five or six minutes, gets caught, placed back, refilled with propellant in 30 to 40 minutes, and a ship placed on top. It could refly every hour or two.
The next goal is to catch the ship.
Elon: We haven’t done this yet, but we will.
[A video shows a render of a Starship gently caught by chopsticks.]
Elon: We hope to demonstrate this later this year, maybe in two or three months. The ship would be placed on the booster, refilled, and flown again. The ship takes longer because it orbits Earth a few times until the ground track returns to the launchpad. It’s intended to be reflown multiple times per day.
RAPTOR 3
Elon: This is the new Raptor 3, an awesome engine! Big hand to the Raptor team. Raptor 3 requires no basic heat shield, saving mass and improving reliability. A small fuel leak will leak into the flaming plasma and not matter, unlike a boxed engine where it’s scary. It’ll take a few tries, but it’ll massively increase payload capability, efficiency, and reliability. It’s alien technology. Industry experts thought an incomplete Raptor 3 picture wasn’t firing, but it was at unprecedented efficiency.
[Lots of cheers and applause.]
Elon: That’s one clean engine. We simplified the design, incorporated secondary fluid circuits and electronics into the structure, so everything is contained and protected. It’s a marvel of engineering.
PROPELLANT TRANSFER
Elon: A key technology for Mars is orbital propellant transfer, like aerial refueling for airplanes, but for rockets. It’s never been done but is technically feasible. Two Starships get together; one transfers fuel and oxygen—almost 80% oxygen, just over 20% fuel. A Starship with payload goes to orbit, others refill its propellant, and then it departs for Mars or the Moon. We hope to demonstrate this next year.
PLASMAJET TESTING
Elon: Mars’ atmosphere is ~95% CO2. The heat shield entering Mars encounters more than twice the atomic oxygen compared to Earth. Developing a reusable orbital heat shield is extremely difficult. Even the Shuttle’s required months of refurbishment. Only advanced ceramics, glass, aluminum, or carbon-carbon survive reentry stresses without eroding or cracking. This will be the first reusable orbital heat shield, needing extreme reliability. It’ll take years to hone, but it’s achievable within physics. Mars’ CO2 atmosphere becomes plasma, producing more free oxygen than Earth’s (~20% oxygen), oxidizing the heat shield. We test rigorously in a CO2 atmosphere for both Earth and Mars.
MARS ENTRY HEATSHIELD
Elon: Derived from Starship’s current heat shield, we want the same structure and material for Earth and Mars to test hundreds of times on Earth before Mars, ensuring reliability.
NEXT GEN STARSHIP
[The video shows a taller, majestic Starship.]
Elon: Next-generation Starships have improvements. It’s taller, with a better interstage between ship and booster. Struts allow flame from hot staging—lighting ship engines while booster engines fire—to exit easily, and we bring the interstage back instead of discarding it.
SUPER HEAVY
- HEIGHT (m) 72.3
- PROPELLANT CAPACITY (t) 3650
- LIFTOFF THRUST (tf) 8240
[Excited reaction from SpaceX engineers due to increased propellant capacity and thrust.]
Elon: A little taller, from 69 meters to 72 meters. Propellant capacity may push to 3,700 tons, long-term maybe 4,000 tons. Liftoff thrust will keep rising, ultimately close to 10,000 tons. The booster looks naked because Raptor 3 engines don’t need a heat shield, standing in flaming plasma. It’s lighter and looks amazing.
STARSHIP
- HEIGHT (m) 52.1
- PROPELLANT CAPACITY (t) 1550
- THRUST (tf) 1600
Elon: The ship is longer, more capable, moving to 1,550 tons of propellant, likely 20% more long-term. The heat shield is sleeker, with smooth boundaries, no jagged tiles. It looks sleek. This version has six engines, but a future version will have nine. Starship version three achieves all key elements. New technology takes three major iterations to work well. With Raptor 3 and Starship/Booster version 3, we’ll achieve a rapidly reusable, reliable rocket with orbital refilling—everything needed to make life multiplanetary. We aim to launch version three by year-end.
FUTURE STARSHIP
[An image of three Starships shows progress and future plans.]
Elon: The left is current, the middle is by year-end, and the right is long-term. The future Starship is 142 meters tall (current: 121 meters, next-gen: 124.4 meters). The middle version will be Mars-capable, followed by performance improvements. Like Falcon 9, we’ll make it longer and increase payload. By year-end, it’ll be capable of making life multiplanetary, then we’ll hone efficiency, reduce cost per ton and per person to Mars, and make it so anyone can move to Mars to build a new civilization. It’s the best adventure possible.
[Lots of applause.]
Elon: Ultimately, we’ll have 42 engines, as prophesied by Douglas Adams in The Hitchhiker’s Guide to the Galaxy. The answer to life’s meaning is 42, so the Starship stack will have 42 engines.
[Lots of applause.]
MASS TO ORBIT
Elon: It’s remarkable—200 tons payload to orbit with full reusability, twice the Saturn V Moon rocket’s capability, which was fully expendable. Starship is fully reusable.
MOON BASE ALPHA
Elon: Without reusability, Starship would have ~400 tons to orbit. It’s a big rocket needed for multiplanetary life. Along the way, we could have a Moon base like Moonbase Alpha, a gigantic science station for universe research.
MARS TRANSFER WINDOWS
Elon: You can go to Mars every 26 months. The next opportunity is November–December next year, in ~18 months. We’ll try for it, with a 50-50 chance if we figure out orbital refilling in time. If achieved, we’ll launch the first uncrewed Starship to Mars by year-end.
[Lots of applause.]
Elon: The distance to Mars is ~1,000 times farther than the Moon. You create an elliptical orbit with Earth at one point and Mars at the other, timing the ellipse to intersect Mars. This is shown on Starlink Wi-Fi routers. Starlink funds Mars missions. Thanks to everyone supporting Starlink—you’re helping make humanity a space civilization.
CANDIDATE BASE LOCATIONS
Elon: We’re looking at the Arcadia region, a lead candidate due to ice for water and suitable terrain. It’s my daughter’s name, too (smiling). First Starships will gather critical data.
Elon: First flights will send Optimus robots to explore and prepare for humans. If we launch by year-end, arriving in 2027, it’ll be epic to see Optimus on Mars. Two years later, if landings succeed, we’ll send humans to build infrastructure. We might do two robot landings before humans, just to be safe.
MARS 2028
Elon: Develop power generation, mining, construction, propellant generation, habitats, communications, and more.
[Elon shows an awe-inspiring picture of Optimus bots on a construction beam above Mars.]
COMMUNICATIONS ON MARS
Elon: We’ll use a Starlink version for Mars Internet. Even at light speed, communication takes 3.5–22 minutes due to Mars’ position. High-bandwidth communication is challenging, but Starlink will achieve it.
HUMANS ON MARS
Elon: Subsequent missions will carry more people and thousands of tons of cargo, laying groundwork for a permanent presence. The goal is to make Mars self-sustaining quickly. Launch pads may be farther for safety. Mars needs lots of solar power. Initially, you’ll need Mars suits and glass domes until terraforming.
Elon: We aim to transfer over 1 million tons per Mars window for a serious civilization.
SPACEPORTS
Elon: We’ll need many spaceports. With transfer windows, 1,000–2,000+ ships gather in orbit like Battlestar Galactica, then depart. Mars needs hundreds of landing pads to handle thousands of inbound ships.
Elon: This is an incredible city on another planet, a new world. Martians can rethink civilization—government, rules, everything. It’s up to them. Let’s get it done!
