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…

How to use Grok Bot to block spam calls and texts
Musk told users to ask Grok Bot to scrub their phone numbers from spam lists.
Elon Musk has a new use case for Grok Bot, and it is the spam call. On Thursday he replied to an X user named Arash with a short instruction: “Ask your @Grok @Bot to remove your phone number from spam call & text lists!” Arash had said he got tired of the calls, had an AI bot find his number on listing sites and file removal requests, and packaged the process as a free skill for others.
The skill is called Spam-Call Scrubber, which is described to find a phone number on people search sites and data brokers, submits the opt outs, completes the confirmation emails those sites send back, and rechecks on a schedule the user picks. Using it requires the Grok Bot app. The pitch is time saved, since most broker opt outs sit behind separate forms on separate sites.
Ask your @Grok @Bot to remove your phone number from spam call & text lists!

Musk said Grok Bot now gives each bot its own email address, and that it can detect scam emails. On Thursday he also said SpaceX would make users whole if the bot botches a purchase or leaks a card, then told users to shop away from Amazon after the retailer blocked the agent, as Teslarati reported. The terms of service we reviewed at the time put responsibility for what an agent does on the user.
For Tesla owners, Grok Bot is not just a phone app. Tesla brought Grok Bot into its vehicles on September 22, and we argued earlier this week that the Cybercab’s real advantage may be the errands it runs during a ride. Every Cybercab and the rest of the Model Y Robotaxi fleet has it enabled. The more routine tasks like this one become, the more a rider has reason to hand over something personal in the back seat.
The new Spam-Call Scrubber skill can be downloaded for free and works on sites that honor removal requests, while noting that listings can reappear, and illegal robocallers do not check any registry. Whether Spam-Call Scrubber cuts anyone’s call volume is something the first wave of users will find out, and Musk’s endorsement guarantees that wave is coming.
Investor's Corner
Tesla’s flying Roadster just revealed something bigger than the car
Analysts say the Roadster demo puts a Tesla and SpaceX merger back on the table.
The Roadster unveiling near Waco ended Thursday night, and by Friday morning much of the investor reaction had less to do with the car than with who owns the rocket technology inside it.
Wedbush analyst Dan Ives said the event “puts the Tesla/SpaceX relationship on the table in a tangible way,” pointing to the propulsion, pressure vessel and control hardware sitting on a Tesla product. Gene Munster of Deepwater Asset Management called the demo “a ridiculous display of engineering” with “no commercial value” beyond embarrassing traditional automakers, though he said it showed Musk wants the two companies together.
The more specific forecast came a day earlier from Barclays. Analyst Dan Levy told clients a deal could be announced before Tesla’s annual meeting, which must happen by December 6, and that an announcement in late October or early November could make shareholder approval harder. Barclays expects SpaceX to be the buyer in an all stock deal, with Tesla holders receiving SpaceX shares at a premium, based on market values of roughly $2.1 trillion for SpaceX and $1.5 trillion for Tesla. If nothing lands around the meeting, the bank still sees an announcement within 6 to 12 months.
The Roadster demo just added more weight to merger speculations. Tesla’s demo used cold gas thrusters and pressure tanks of the kind SpaceX uses on Falcon 9, and Musk described the car as a collaboration between Tesla and SpaceX engineers, as we mentioned in our breakdown of the three Roadster configurations.
Musk has not publicly addressed a deal since the event, as far as we have seen. His most direct answer remains the one he gave at the All In Summit, when he said that with so much collaboration, “who can imagine what action one might take” without ruling anything out. Ives has held to a 2027 timeline since his March note, and Musk pushed back on the China piece of the speculation when ARK floated a year end announcement in August.
The next test is Tesla’s third quarter earnings call on October 21. However, we recall in July that Musk told analysts, “we can’t talk about combining companies and that kind of thing on an earnings call,” so a clear answer wouldn’t be expected.

How Tesla’s Roadster fan system and thrusters are built to dominate the corners
Tesla’s Roadster uses fans, active wings and cold gas thrusters to create grip at any speed.
Tesla’s new Roadster is best known for flipping through the air in Texas, but the technology that matters most for a race track is the stuff that keeps it on the ground. Tesla’s Roadster page describes a multi-mode fan and ground sealing system that acts as a downforce generator, pulling air out from beneath the car. Tesla says it provides enough suction to hold the vehicle upside down, even when stationary.
That is the key difference from the wings and diffusers on a normal supercar. Conventional aero only makes downforce when the car is moving, and it grows with speed, so a car has the least grip in the slow corners and under hard braking. A fan system makes downforce at any speed. Tesla’s patent, which we covered last year, describes fans and deployable skirts that create sealed or partially sealed regions under the car, with the fans extracting air to lower the pressure and increase grip and stability.
Still processing this … the most unreal thing I’ve seen. https://t.co/HtEuvnkZjY

Tesla pairs that with active wings, a next generation steer by wire system and a Track Mode that lowers the car and changes the suspension, with high downforce and low drag settings for the circuit. To keep weight down, Tesla points to magnesium, titanium and carbon fiber, manual controls and a fixed seat position, which it says lets the car respond to driver inputs almost instantly.
Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds
The cold gas thrusters are the other half. On the Thrust version they sit at the rear and Tesla says they take the car from 0 to 60 mph in under 0.9 seconds, while the Rocket version adds perimeter thrusters for forward, upward and lateral rotational movement. Tesla says the all electric actuators make micro adjustments within a fraction of a second.

Musk has been talking about records for years. In June 2019 he said, “We’re going to do things with the new Roadster that are kind of unfair to other cars.” That September, when a follower asked whether the Roadster would beat the Nürburgring production car record, he replied with one word, “Absolutely,” as we reported at the time. In February 2024 he said Tesla had “radically increased the design goals” for the car and that its sub one second 0 to 60 time would be “the least interesting part.”
There are caveats. Tesla has not published a lap time or a verified cornering figure, so the record talk is still a promise rather than a result. Tesla also says the car is not approved for public road use, and the thruster features are limited to the Rocket trim, which is invite only. Fan cars have also been banned or withdrawn before, and getting a sealed underbody to work on a rough public road is a harder problem than on a smooth track. The first real test will be an official lap at a circuit.
