SpaceX's workhorse rocket is almost halfway to reaching ambitious reusability goals
Thanks to a recent cluster of major milestones, SpaceX’s family of Falcon 9 and Heavy rockets are rapidly nearing the halfway point along the path to several ambitious goals for booster and fairing reusability.
Back in the early 2010s, SpaceX’s CEO Elon Musk’s original dream was to make Falcon 9 and Falcon Heavy 100% reusable, meaning that the company would need to find ways to reliably recover boosters (first stages), payload fairings (or Dragon spacecraft), and the rocket’s upper (second) stages. The concept of Falcon 9 second stage reuse actually survived all the way into 2018 before Musk ultimately conceded defeat, accepting that Falcon 9 and Heavy simply didn’t offer the performance necessary to make full reusability a worthwhile investment. The concept, however, still lives on in SpaceX’s next-generation Starship launch vehicle.
This does mean Falcon rockets will never be fully reusable, but it’s still up to SpaceX to decide how far they’ll push the envelope with the rockets’ existing reusable hardware. At the moment, it appears that a vast majority of Falcon rockets will be able to be routinely recovered and reused, capitalizing on the fact that Falcon 9 and Falcon Heavy boosters already represent some 50-75% of the cost of building each two-stage rocket. While Falcon upper stages and Dragon trunks will never be reused, both booster and payload fairing reuse are rapidly approaching their own unique halfway points on the path to ambitious reusability targets.
Shortly after SpaceX’s January 29th Starlink V1 L3 launch, carrying the third batch of 60 upgraded v1.0 satellites to orbit, twin fairing recovery ships GO Ms. Tree (formerly Mr. Steven) and Ms. Chief teamed up for their second-ever simultaneous fairing catch attempt. Ms. Chief – only active since November 2019 – reportedly just barely missed her first successful catch, while Ms. Tree managed to snag one of the Falcon 9 fairing halves in her massive net – the ship’s third successful catch.
Worth an estimated $3M per half according to CEO Elon Musk, Falcon 9’s payload fairing represents approximately 10% of the rocket’s total manufacturing cost. Made out of a carbon fiber and aluminum honeycomb composite material, fairings also also takes a disproportionate amount of time and space to produce – primarily due to their large size (a school bus could comfortably fit inside a fairing) and the need for commensurately large curing ovens. That composite honeycomb structure also makes it relatively easy for Falcon payload fairings to suffer from corrosion when dunked in seawater, leading SpaceX to the seemingly bizarre solution of installing giant arms and nets on ships.
Catching fairings has proven to be incredibly unforgiving, however, and SpaceX has simultaneously worked to make its Falcon fairings much more waterproof (and thus resistant to corrosion) while keeping them as light as possible. In fact, SpaceX’s first fairing reuse occurred less than three months ago and used two halves that previously landed in the Atlantic Ocean, demonstrating that difficulties reliably catching fairings will not stand in the way of reuse.
Ms. Chief missed her January 29th catch attempt, she still managed to fish her fairing half out of the ocean, while Ms. Tree’s successfully-caught half means that SpaceX ultimately recovered the full Starlink V1 L3 fairing. With a little luck, that recovered fairing will launch again in the near future.
Five for 5
Simultaneously, SpaceX is making excellent progress along the path to airliner-like rocket reusability. In November 2019, on the same Starlink mission that debuted flight-proven fairings, Falcon 9 booster B1048 became the first SpaceX rocket to launch (and land) four times. Less than two months later, Falcon 9 B1049 doubled down on that reusability milestone, becoming the second booster to launch and land four times, followed by Falcon 9 B1046 just 12 days later. Falcon 9 B1046 was (intentionally) destroyed after its fourth launch, precluding a fourth landing attempt, but it emphasizes just how confident SpaceX is in Falcon 9’s Block 5 upgrade.
Designed to allow each Falcon 9 and Heavy booster to perform a minimum of 10 launches and landings, the Block 5 upgrade is potentially just a few weeks away from reaching the halfway point along the path to that ambitious reusability design goal. Speaking at the NASA Kennedy Space Center earlier this month, a SpaceX engineer recently revealed that a Falcon 9 booster would conduct its fifth launch in support of a Starlink mission (either Starlink V1 L4 or L5) scheduled no earlier than (NET) mid-to-late February.
Pictured above, Falcon 9 booster B1048 – the first to launch four times – is the likeliest candidate for the first fifth flight of a SpaceX rocket. If the booster’s reuse goes as planned, it’s safe to say that Falcon 9 B1049.4 will follow closely on the heels of its predecessor with its own fifth-flight milestone. All things considered, SpaceX’s workhorse rocket is rapidly approaching the zenith of its theoretically-achievable reusability.

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.

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.
