SpaceX rolls out Starship, stacks world’s largest rocket, and aces Starlink launch hours apart

In 15 hours, SpaceX has rolled a new Starship to its South Texas launch and test facilities, reassembled the world’s largest rocket, launched Starlink satellites to orbit, and recovered a reused Falcon 9 booster in port.

The burst of activity began around sunset at SpaceX’s Starbase rocket factory in Boca Chica, Texas when a new orbital-class Starship prototype left its ‘nest’ for the first time. SpaceX rolled the Starship – known as Ship 25 – a few miles down the highway to its nearby launch and test facilities, where workers connected it to a large crane and waited for daylight.

Around 9 am CDT the following day, October 20th, SpaceX lifted Ship 25 onto one of two Starship test stands, where it will eventually attempt to complete several qualification tests. While Ship 25 was still suspended in mid-air, the Starbase launch pad’s orbital launch tower began lifting a different prototype, Ship 24, into the air with a pair of giant ‘chopsticks’ – mechanical arms designed by SpaceX to replace one of the largest mobile cranes in the world.

Then, while it was stacking Ship 24 on top of Super Heavy Booster 7 and installing Ship 25 on a test stand, a Falcon 9 rocket carrying 54 new Starlink satellites lifted off from Cape Canaveral, Florida. Minutes prior, SpaceX finished craning a reused Falcon 9 booster off one of its drone ship landing platforms in a port ten miles south.

Starlink 4-36 was SpaceX’s 48th launch of 2022 and 56th launch in less than 12 months, so its Falcon launch program simply doesn’t have time to waste. Drone ship Just Read The Instructions (JRTI) returned to port with Falcon 9 booster B1069 about 12 hours before the rocket was transferred from the ship’s deck to a stand on SpaceX’s Port Canaveral dock space. The company will now be able to retract B1069’s legs and complete any necessary booster and drone ship refurbishment, ensuring that both will be ready for their next missions in the near future.

Back in Texas, SpaceX is scheduled to begin thoroughly testing a fully-stacked Starship rocket for the first time as early as Monday, October 24th. Ship 24 was reinstalled on Booster 7 for that purpose after SpaceX disassembled the pair for several days, possibly due to forecasts of high winds. The test campaign is expected to begin with the first full wet dress rehearsal (WDR) of a two-stage Starship, meaning that the rocket will be fully loaded with thousands of tons of liquid methane and oxygen propellant and run through a simulated launch countdown that ends just before engine ignition.

If successful, SpaceX will likely restart Booster 7 static fire testing and continue to work its way up to the first simultaneous ignition of all 33 of its Raptor 2 engines. If the pair survive WDR and static fire testing, SpaceX could begin preparing the same rocket for Starship’s orbital launch debut.

If significant issues arise during testing, SpaceX could choose to retire Ship 24 and/or Booster 7 and move on to a new and improved pair: likely Ship 25 and Booster 8 or 9. Already complete, Super Heavy Booster 8 has been sitting untouched at Starbase’s launch site for weeks, making it uncertain whether SpaceX actually intends to test or use the prototype. Booster 9 is just one stack away from completion, at which point it will be ready to begin proof testing. According to CEO Elon Musk, B9 features significant improvements that will make it more resilient to mid-flight Raptor engine failures. It could also be the first Super Heavy booster with no hydraulic system, thanks to a new version of Raptor that replaces hydraulic thrust vectoring with a battery-powered alternative.

Starship S25 could kick off its own proof testing as early as next week. Unlike Ship 24, Ship 25 went straight from the factory to a test stand that has been modified with six hydraulic rams. Those rams will simulate the thrust of six Raptor 2 engines (up to ~1400 tons or 3.1M lbf) while the Starship is simultaneously loaded with cryogenic liquid oxygen and/or nitrogen, combining peak mechanical and thermal stresses into one test. Once Ship 25 is done, it will be rolled back to the factory for Raptor engine installation and will eventually return to the pad for static fire testing.

Tesla Cybercab Event: what to expect from Austin

Published

Tesla is set to launch Cybercab on Thursday at an event in Austin, Texas, which will officially bring the company’s first steering wheel-less and pedal-less vehicle to a limited number of consumers for the first time.

The event, which is invite-only, is still thin on details: we’ll be there, and it seems the event will be held at Gigafactory Texas, but the launch of this vehicle truly relies on it being operational outside of the factory and on public roads.

Nevertheless, there are some big things to expect, and other things to temper expectations on. For what it’s worth, we believe this event could be perhaps the biggest indication that Tesla is ready to truly enter a new phase and chapter in its historic story.

Tesla Cybercab’s First Foray into the Public with Real-World Riders

Cybercab will likely hit the streets of Austin and the surrounding areas, likely in the established geofence that Tesla has expanded on for the past 14 months. Just yesterday, Tesla expanded it once again by 9 percent.

Tesla will put, for the first time, a vehicle without any manual controls on public roads, likely without any help from teleoperators. This is a truly groundbreaking development if it comes through in this fashion: it would be groundbreaking for Tesla to roll out a truly driverless ride-hailing vehicle.

Cybercab Has Already Been Unveiled

This is not an unveiling event. Cybercab has been released for nearly two years, as Tesla first showed it to the public on October 10, 2024.

FIRST LOOK: Tesla ‘Cybercab’ Robotaxi makes its global debut

While there is some small speculation that Tesla could release the Roadster at the event as a surprise, it seems more likely the focus will be on the Cybercab and the huge accomplishment that will come with releasing a vehicle with no manual controls.

There Will Be a Lot of Hype

What’s important to remember about the Cybercab event is that Tesla will continue to prioritize safety and the rollout will likely be slow, just as it has been with Robotaxi.

One of the biggest complaints about Robotaxi is vehicle population, and the fact that the wait for a ride, at least in some instances, has been longer than most want to admit.

Tesla Cybercab fleet grows in Austin ahead of launch event

It will take time for this project to truly scale. It will take time for Tesla to roll this out in a large fashion. The important thing to note is that they are doing it, and they’re doing it with a vehicle that is completely engineered and built internally. That’s something no other ride-hailing service can say.

SpaceX would not exist if this crucial early launch failed, Musk says

Published

Elon Musk recently restated a fact that still defines SpaceX’s origin story: if Falcon 1’s fourth launch had failed, the company would not exist. The comment answered a reminder that after three consecutive losses, SpaceX had money for only one more attempt.

On X, Peter Diamandis said that the present-day acknowledgement of SpaceX’s success does not discount the rough start the company had. “Almost nobody remembers that Elon’s first rocket failed three times, and there was money for exactly only one more attempt.”

Musk said, “If the 4th launch had failed, SpaceX would not exist.”

In late 2008, the firm was nearly out of cash. Another failure would have ended payroll, closed the Hawthorne factory, and left the Falcon 9 and Dragon programs as unfinished drawings.

The first flight lifted off from Omelek Island on 24 March 2006. Thirty-three seconds later, a corroded aluminum fitting on a fuel line leaked. Kerosene ignited around the Merlin engine, control was lost, and the vehicle came apart. The small DARPA payload, FalconSAT-2, survived the short flight only to land on a storage shed near the pad. Investigators later traced the fitting to a materials mix-up that should never have reached the rocket.

Flight 2, on 21 March 2007, looked far better at first. The first stage burned cleanly and handed off to the Kestrel-powered upper stage. The vehicle crossed 100 kilometers and reached a peak of about 289 kilometers. Then propellant slosh in the second-stage tank started a circular coning motion that grew until the engine shut down. Telemetry faded as the stage tumbled, and SpaceX had reached space but not orbit. Over the next year, the team redesigned everything from the ground up, including tanks, baffles, and the new regeneratively cooled Merlin 1C.

That engine flew on Flight 3 on 2 August 2008. The first stage performed almost perfectly and reached 217 kilometers. After main-engine cutoff, leftover fuel in the cooling channels produced a faint residual thrust, roughly 10 pounds per square inch of chamber pressure. On a Texas test stand, the effect was invisible beneath ambient air pressure. In vacuum it was enough to push the spent first stage back into the second stage after separation. The stages collided, the upper stage spun, and the mission was lost. Musk later said a slightly longer delay before staging would have saved the flight.

Six weeks later, the team assembled Flight 4 from remaining parts and flew it on 28 September 2008 at 23:15 UTC. The payload was Ratsat, a 165-kilogram aluminum mass simulator built in-house. Staging was delayed so residual thrust could decay. The Kestrel ignited, the fairing split away, and nine and a half minutes after liftoff the vehicle was in orbit. After a coast, the second stage restarted, settling into a 621-by-643-kilometer path at 9.35 degrees inclination. Falcon 1 became the first privately developed liquid-fueled rocket to reach Earth orbit. Musk called the insertion “middle of the bull’s-eye.”

SpaceX restores a Falcon 1 rocket for 10th anniversary of first launch success

That success unlocked NASA’s Commercial Resupply Services award later that year. Without it, there would have been no Falcon 9, no reusable first stages, and no Dragon cargo or crew flights to the International Space Station. Launch prices would have remained far higher. Starlink’s constellation would not exist; broadband from low Earth orbit would still be a paper concept.

Ride-share markets, high launch cadence, and the current pace of lunar and Mars hardware would be years behind. Communications, Earth observation, and the cost of putting anything into space would look more like the 2000s than the 2020s.

One extra second of residual thrust in August 2008 would have written a different decade.

Tesla surges Robotaxi fleet ahead of Cybercab launch event

Tesla’s unsupervised robotaxi fleet quietly grew sevenfold in three weeks just before Cybercab Day arrives.

Tesla’s unsupervised Robotaxi fleet has grown far faster than the public numbers suggested, and the timing lines up with the company’s biggest autonomy showcase yet. According to data compiled by the crowdsourced Robotaxi Tracker, Tesla now has nearly 200 vehicles operating without a safety monitor across Austin, Dallas and Houston, yielding a roughly 7X increase in about three weeks.

The jump lands four days before this week’s Tesla Cybercab launch event in Austin, where the company plans to show off its purpose-built, two-seat robotaxi with no steering wheel or pedals in a live commercial setting for the first time. Stick with us on X and Facebook for live reporting from the event.

The strategic logic is straightforward. Tesla has spent the past year scaling Robotaxi in small, deliberate steps, first widening geofences, then extending operating hours, then quietly growing fleet size, usually with little advance notice. Ashok Elluswamy told investors on the Q2 earnings call that the program had logged more than 380,000 unsupervised miles with zero notable incidents, a safety record the company has leaned on to justify moving slowly. Critics have used the flip side of that caution, a fleet that appeared stuck around two dozen vehicles for months, as evidence that Tesla’s driverless ambitions were outrunning its actual deployment.

A fleet quietly scaling to nearly 200 vehicles right before Cybercab Day undercuts that argument without Tesla having to say anything about it directly. It also sets up the event to do double duty. Rather than simply introducing new hardware, Tesla can point to an operating base of unsupervised Model Ys already running at meaningful scale, then argue the Cybercab, which uses the same underlying Full Self-Driving stack according to earlier coverage of the fleet’s software upgrades, is a natural next steps. Tesla has separately been registering the two-seat Cybercabs with Texas regulators this week, with the count climbing from seven to 45 in a matter of days.

The two ramps, one in software-driven Model Y deployment and one in physical Cybercab registrations, are happening in parallel rather than in sequence. That suggests Tesla wants Thursday’s event to land as proof that the robotaxi business is already running at scale, not just a reveal of a new vehicle shape. Whether the unsupervised numbers hold up once Cybercabs start mixing into the same fleet is the detail worth watching once the event wraps.
