SpaceX completes vast Mr Steven arm upgrades for quadruple-sized net
Scarcely 48 hours after they began, SpaceX technicians have already completed installation of all four of Falcon fairing recovery vessel Mr Steven’s new and dramatically larger arms, as well as eight giant struts. All that remains to be installed is an upgraded net, said by CEO Elon Musk to have four times the area of its predecessor.
Put simply, it’s difficult to express how large these upgraded arms really are, and photos still only give a partial sense of their scale. SpaceX technicians busy installing the new arms on July 10th nevertheless offer a fleeting appreciation of the true size of this new payload fairing recovery apparatus, which will hopefully see its first operational debut in just two weeks with a fairing recovery attempt after the Iridium-7 Falcon 9 mission, July 25th.

All arms on deck
While it’s difficult to estimate from photos alone, it appears that Mr Steven’s new arms are minimum of roughly 65 meters squared, assuming a square aspect ratio. In other words, the vessel’s next and newest net could have an area as large as 3600 square meters (~40,000 square feet, ~0.85 acres), easily more than quadruple the size of Mr Steven’s previous net. For comparison, the massive autonomous spaceport drone ships (ASDS) SpaceX often recovers its Falcon 9 and Heavy boosters aboard have a usable landing area of roughly 45,000 square feet, a little more than 10% larger than Mr Steven’s new net.
With these vast new arms, struts, and (soon enough) net, SpaceX is likely as close as they have ever been to successfully catching a Falcon 9 fairing, an achievement that would likely allow the company to begin reusing the large carbon fiber-composite shrouds almost immediately. Critically, although SpaceX appears to have begun attaching recovery hardware to both fairing halves in recent West Coast attempts, it remains to be seen whether Mr Steven’s new claw apparatus will be able to catch both halves, thus closing the gap on fairing recovery without necessitating the leasing and modification of perhaps three additional copies of the vessel.

Adding three recovery-critical ships (two for West Coast missions, two for East Coast missions) to SpaceX’s already massive blue-water fleet could significantly raise the operating costs of each recovery attempt, as well as generally adding considerable complexity to the orchestration of those fleets come launch time. Perhaps not. Still, if Mr Steven sees success with his 4Xed net and arms, chances are very good that SpaceX will lease and modify another Fast Supply Vessel – if they already haven’t done so – to provide the company’s higher-volume East Coast launch facilities with their own, dedicated fairing catcher. Mrs Steven awaits…

Zeroing in on Falcon fairings
Worth noting, SpaceX may have already halved the error margin officially advertised for the parafoil guidance units it procured from Canadian supplier MMIST, apparently missing Mr Steven by about 50 meters while MMIST suggests a 50% chance of successfully landing a payload in a 100-meter sphere. Given the significant expense likely incurred by designing, building, installing, and testing two distinct net and arm systems aboard Mr Steven, it’s safe to say that SpaceX engineers and technicians believe there is a very strong chance that the newest solution will successfully close the fairing recovery gap, said by CEO Elon Musk to be a rather literal 50 meters between the vessel’s old net and the unforgiving ocean surface.
With an additional 30 meters (~100 feet) of reach in both axes, the new net alone may be able to shrink that error margin by ~60%. Perhaps the fact that it also appears to cover (and thus protect) Mr Steven’s wheelhouse will allow the vessel more leeway to aggressively maneuver as the fairing nears touchdown, providing that final 20-meter leap to slip his net under the fall halves.
In the meantime, we will ponder who exactly SpaceX is procuring a 40,000 square foot net from.

Incredibly, this artist rendering of a much larger net installed on Mr Steven was perhaps two or more times smaller than the solution now installed on the vessel. (Reese Wilson)

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.
