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 to open source Model S and Model X designs and software
In a move echoing its earlier commitment to open innovation, Tesla CEO Elon Musk announced recently that the company plans to make the design and software of its Model S and Model X fully open source.
This follows the same approach Tesla took with its original Roadster, releasing all available design, engineering, and diagnostic materials in November 2023 so that “whatever we have, you now have.”
Just as Tesla made the original Roadster design & software open source, we plan to do the same with Model S & X
— Elon Musk (@elonmusk) July 24, 2026
The Model S, introduced in 2012, was Tesla’s first mass-produced vehicle and a groundbreaking luxury electric sedan. It offered impressive range, rapid acceleration, and over-the-air software updates that redefined expectations for electric cars.
The Model X, launched in 2015, built on that foundation as a high-performance electric SUV notable for its distinctive falcon-wing doors, spacious interior, and advanced safety features. Both models served as flagships that helped establish Tesla as a leader in the EV industry and popularized long-range battery-electric vehicles.
Production of the Model S and Model X was wound down earlier in 2026, with manufacturing ending in the second quarter. Tesla redirected the Fremont factory space previously used for these vehicles toward higher-priority projects, including Optimus humanoid robots and the Cybercab autonomous vehicle.
By the time of Musk’s open-source announcement, custom orders had closed and only remaining inventory was available.
Open-sourcing the designs and software offers several clear advantages. Owners of these aging but still capable vehicles gain better access to technical documentation, diagnostic tools, and software resources, making independent repairs and modifications easier and more affordable.
Independent repair shops and third-party specialists can support the large existing fleet without relying solely on Tesla’s service network. Enthusiasts and engineers can study real-world implementations of Tesla’s battery, powertrain, and software systems, potentially accelerating broader industry progress in electric mobility.
The step aligns with Tesla’s 2014 patent pledge and its overall mission to advance sustainable transport by sharing hard-won knowledge rather than locking it behind proprietary walls.
By releasing these materials now that the models have left production, Tesla ensures continued support for its early adopters while freeing internal resources for future technologies. The open-source release of the original Roadster already enabled simulations, community projects, and deeper technical understanding.
Extending that practice to the Model S and Model X should deliver similar benefits on a larger scale, helping keep these influential vehicles relevant and repairable for years to come

Tesla flexes incredible Robotaxi metric that skeptics will hate
Tesla flexed one incredible Robotaxi metric during the Q2 Earnings Call that skeptics have to hate to hear. The company’s platform has already driven more than 380,000 miles of unsupervised ride-hailing across several states with no notable incidents.
During the company’s Q2 Earnings Call on Wednesday, Vice President of AI, Ashok Elluswamy, said:
“First of all, I’d like to state that the Robotaxi program has been operating extremely well. Especially in terms of safety, the program has had an impeccable safety record. We have driven more than 380,000 miles of unsupervised Robotaxi, now across six cities in two different states. We have had zero notable incidents. Any reports have been of other actors impacting us when we were stationary. I like to emphasize how safe the operation has been so far. Zero notable incidents over 380,000 miles.”
Elluswamy’s claim over Robotaxi miles is a significant milestone for Tesla in the grand scheme, especially considering this is a sizeable number of miles without any incident.

Tesla’s self-driving approach is much different than that of other companies. Tesla has maintained that vision is the only thing needed to have a solid and effective self-driving suite. Many self-driving companies utilize things like LiDAR, sensors, and other elements to improve performance, but Elluswamy sent a jab at those who believe it’s needed.
“Historically, the so-called experts have always claimed that you need LiDARs, radars, HD maps, and the entire kitchen sink to drive safely. Here we show that such is not true. You can have safe, comfortable, and affordable autonomy with just cameras. This record should be a huge validation of Tesla’s entire AI approach.”
The feat of accumulating this many miles without any driver behind the wheel is impressive. The thing is, Tesla is also doing this across several different locations, with varying traffic rules, pedestrian levels, weather patterns, and other important factors.
While Tesla is not ready to roll out an unsupervised platform completely, it is a slow but steady indication that the company is well on its way to figuring things out.
The company’s attitude toward expansion is slow, safe, and controlled, and despite this huge milestone, it will still be some time until we see Tesla truly unleash unsupervised rides more aggressively.

SpaceX Starship just nailed something it’s never done before
SpaceX’s Starship flew successfully Friday, landing both stages and deploying its first Starlink V3 satellites.
Starship’s thirteenth test flight delivered exactly what SpaceX needed with a clean liftoff, two successful stage recoveries, and the first real payload the vehicle has ever carried to space. Booster 20 and Ship 40 lifted off at 5:51 p.m. CT from Starbase, and by the time the mission wrapped roughly an hour later, both halves of the rocket had done exactly what they were supposed to do.
Booster 20 separated from Ship 40 a few minutes into the flight and stuck a controlled splashdown in the Gulf of Mexico about six minutes after liftoff. That is a meaningful turnaround from Flight 12 in May, when the booster lost several engines during its boostback burn before a hard water landing attempt.

Starship 40’s performance was arguably the bigger win. The vehicle deployed the first 20 operational Starlink V3 satellites Starship has ever carried, then flew a suborbital arc to a landing in the Indian Ocean that SpaceX commentator Dan Huot called the company’s softest splashdown yet. “This is a dream scenario for this team that’s trying to get this heat shield data,” Huot said on the live broadcast, according to Space.com’s live coverage. “I’m a little over the moon right now. Wow. Lucky number 13.”
Unlike the mass simulators SpaceX flew on Flight 12, these were production Starlink V3 satellites, meant to extend solar arrays and antennas and attempt to link with the broader constellation before reentering minutes later. Getting real hardware through a full deploy sequence on only the second flight of the V3 generation keeps Starship on schedule for the payload work NASA is counting on for future Artemis lunar landings.
What an awesome launch, really seems like everything went super well and it was all incredibly smooth.

The flight also arrives at a moment when SpaceX needed a win. SPCX has traded below its $135 IPO price since mid-July, as Teslarati reported when the mission slipped to Friday, and short interest has climbed to roughly a third of the tradable float. A clean flight will not fix a balance sheet, but it does answer the one question SpaceX absolutely needed answered this week: whether the fixes made after the July 16 abort would hold up under real flight conditions. They did, on both stages, on the first try after the redesign.
SpaceX has not set a target date for Flight 14, though the company has said it wants to push toward an orbital attempt on the next mission. After Friday, that goal looks a lot more within reach.
