SpaceX sets new goals for Falcon booster reuse goals after ten-flight milestone
Speaking virtually at Barcelona’s 2021 Mobile World Congress (MWC), CEO Elon Musk says that SpaceX has already set its sights on even more ambitious reusability goals for Falcon rocket boosters.
Less than two months prior, booster B1051 sent 60 satellites and an upper stage on their way to orbit, simultaneously becoming the first Falcon 9 first stage to ace ten orbital-class launches and landings, crossing a mostly symbolic – but still significant – milestone years in the making. SpaceX competitors – most notably the United Launch Alliance – have often held the ten-flight mark over its head as the latest in a long line of moving goalposts used to discredit, demean, and look down upon reusable rockets and SpaceX’s efforts to realize them.
Not long before it was clear that SpaceX would hit that 10-flight target with at least one Falcon booster, competitors working overtime to rationalize a lack of substantial investment into reusable rockets shifted their goalposts again, expanding rationales to require a fleetwide average of ten flights. Instead of explaining why SpaceX’s reusability plans could never work, as many dozens of aerospace executives have assuredly done over the last 5-10 years, the new attitude du jour is to claim that SpaceX’s ability to achieve its reuse goals was never actually in doubt and that the economics of full booster reuse simply can’t make economic sense!
Now, five and half years after Falcon 9’s first successful booster landing, four years after SpaceX’s first successful booster reuse, and seven weeks after a Falcon 9 first stage’s first ten-flight milestone, Elon Musk says that some of the company’s fleet of boosters are already “slated to fly 20 or possibly 30 times.” Never one to personally rest or allow his companies to rest on their laurels, SpaceX now has a new target to strive for as teams work to ramp and sustain Falcon 9’s launch cadence at record-breaking levels.
Back before Falcon 9’s Block 5 upgrade debuted in May 2018, Musk held a press conference in which he made it abundantly clear that it was SpaceX’s “unequivocal intent” to launch new Falcon boosters up to 10 times without refurbishment. Three years later, although SpaceX ultimately abandoned plans to recover and reuse Falcon 9’s upper stage to prioritize Starship development, Musk’s dream of cutting the cost of launch by a full magnitude has almost been realized.
Technically, if SpaceX had developed a reusable upper stage, Falcon 9 as it stands today could feasibly cost just ~10% of its list price (~$6 million. Factoring in the cost of a new expendable upper stage for each mission, the actual cost of a modern Falcon 9 launch with a flight-proven booster and payload fairing is closer to ~$18M. However, in the same June 2021 interview, Musk confirmed that the cost of Falcon 9 operations – as in refurbishment, recovery, consumables, and any other recurring work – is just 10% of the cost of launch, effectively confirming that Falcon 9’s Block 5 upgrade really did create a rocket booster that requires virtually no refurbishment.
Back in Musk’s 2018 conference call, he also noted that beyond plans for up to ten flights without refurbishment, Falcon boosters could feasibly be made to fly dozens or even 100+ times with occasional in-depth maintenance – not unlike modern aircraft. Three years later, Musk is now talking about launching certain Falcon boosters 20 or 30 times, while something approximating the recurring maintenance he once described has yet to crop up.
It’s possible, in other words, that SpaceX has found that Falcon 9 Block 5 boosters – which do need some small amount of refurbishment and inspection after each launch – can actually be flown 20 or 30 times without major rework. Ultimately, only time will tell, but Falcon 9 B1051’s 11th flight is expected – this time from the West Coast – as early as late July or August 2021, carrying SpaceX’s first or second dedicated batch of polar Starlink satellites. B1051 arrived at Vandenberg Air/Space Force Base (VAFB) in late June about a month after Falcon 9 B1049 – likely set to become the second booster to complete ten launches.

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.
