SpaceX set to launch its first previously-flown Block 5 rocket tonight
At the same time as SpaceX is readying its first Falcon 9 Block 5 booster reuse, the company’s second flight-proven Block 5 launch is already fast approaching and could be a strong contender to beat the company’s record of 72 days between launches of the same rocket.
A critical milestone for Falcon 9 Block 5
Formerly known as Telkom 4, SpaceX’s 1:18 AM EDT August 7th launch of the Merah Putih (Red and White in Indonesian) communications satellite will place the 5800 kg (12,800 lb) craft into a high-energy geostationary transfer orbit and will become the second heaviest GTO launch completed by SpaceX while still recovering the Falcon 9 booster. More importantly, however, Telkom 4 will also mark a critical milestone for Falcon 9 as the first reuse of a Block 5 booster.

Designed to be many times more reusable and reliable than the already impressive Falcon 9 Full Thrust iterations preceding it, pathfinder booster B1046 could be capable of flying anywhere from 5, 10, or even 100 launches over the course of its flightworthy lifespan. It very well may require some considerable refinements to approach the true goal of orbital Falcon 9 launches with zero refurbishments between flights. CEO Elon Musk discussed those aspirations just before Block 5’s launch debut on May 11:
“We need to basically take the rocket from its landing pad, rotate it horizontal, stow the legs. Take it to the launch pad, attach an upper stage, attach a fairing with a payload. Then transport it out the launch pad, rotate it vertically, load propellant, and fly. And in principle, that is literally all that’s necessary.” – Elon Musk
This is understandably SpaceX’s goal, and it’s unlikely to happen just a few months after Block 5’s debut. Nevertheless, SpaceX appears to be already pushing the envelope of what they’ve previously accomplished with reusable Falcon 9s.

Breaking records four months after launch debut
While B1046 is tracking towards a booster turnaround of roughly 92 days, compared with the current Block 4 booster record of 72 days, it’s worth noting that more than a majority of that time was likely spent in a state of unique analysis for the inaugural Block 5 rocket, involving extensive disassembly. As stated by Musk, “we need to take [B1046] apart to confirm that it does not need to be taken apart.” He also expected that teardown analysis to be “very rigorous”, indicating that B1046 probably deserves the crown for booster turnaround so long as one only accounts for time spent in transport and undergoing refurbishment.
Still, winning by a technicality is never any fun. On that note, SpaceX appears to be tracking towards a true record-breaking rocket reuse, potentially as few as 40 days between launches. Not one to let its other launch facilities be left out, this record-breaking turnaround attempt will occur on the West Coast with Falcon 9 B1048, the recovery of which has been extensively documented by Teslarati photographer Pauline Acalin over the last two weeks. NASASpaceflight.com confirmed that SpaceX intends to reuse B1048 for this mission for the NET mid-September launch and the record ~50 days between flights could help explain an unusually extensive and lengthy analysis of the rocket after it was lifted off drone ship Just Read The Instructions and placed on its dockside recovery stand.

After 10 days of recovery operations and analysis, B1048 was transported to SpaceX’s Hawthorne factory on August 6th, where it will presumably undergo refurbishment in preparation for its next launch. If B1046 and B1048 are representative samples of SpaceX’s growing rocket fleet, their stunningly quick turnarounds (especially for a largely new rocket that debuted less than 3-4 months prior) are likely a sign of things to come as SpaceX gets a handle on the real-world capabilities of its robust Block 5 upgrade.
It’s entirely possible that every Block 5 reuse to come can and will break the previous launch turnaround record, at least up to the point that SpaceX demonstrates a true 24-hour turnaround sometime next year. Stay tuned…

Tesla Cybercab Event: what to expect from Austin
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.
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
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.
