SpaceX tests extra-fast ocean landing, celebrates 50th launch
The happy tragedy of 1044
SpaceX has successfully completed the 50th launch of Falcon 9 a bit less than eight years after its 2010 debut, and has done so in a fashion that almost perfectly captures the veritable tsunamis the company has begun to make throughout the global aerospace industry. After a duo of delays due to hardware issues and range conflicts, this evening’s launch successfully placed Hispasat 30W-6 into a geostationary transfer orbit (GTO), where the massive ~6100 kilogram communications satellite will now spend several months raising its orbit to around 36,000 km (22,000 miles) above Earth’s surface.
Falcon 9 flight 50 launches tonight, carrying Hispasat for Spain. At 6 metric tons and almost the size of a city bus, it will be the largest geostationary satellite we’ve ever flown.

Aside from becoming the heaviest commsat the company has yet to launch into GTO, the mission’s anticipated landing attempt stirred up quite a bit of intrigue and uncertainty in the spaceflight fan community. Stormy Atlantic seas, partially connected to the chaotic weather recently seen on the East coast, proved to be far too dangerous for SpaceX’s eastern recovery fleet and its drone ship, OCISLY, and they returned to Port Canaveral around 48 hours ago, under the watchful eyes of many anxious SpaceX followers. Tragically, this means that the brand new Falcon 9 booster (B1044) – originally expected to attempt perhaps the most difficult landing yet – had to be expended. Although the booster went through its paces as if it were preparing to land, it found no drone ship beneath it once it reached sea level, and subsequently dunked into the stormy Atlantic seas.
However, due to the last-minute nature of SpaceX and Hispasat’s decision to expend the booster rather than delay for better recovery conditions, launch technicians at Pad 40 simply did not have time to remove the rocket’s iconic landing legs and valuable titanium grid fins – the first time their titanium iteration has been chosen for a Falcon 9 to resist extreme reentry heating. Due to massive swells, recovery of even pieces of the expended booster – theoretically following a soft landing – will not be possible, as no SpaceX recovery vessels remained at the planned point of touchdown 400 miles off the Florida coast. Notably, following the successful inaugural flight of Falcon Heavy, CEO Elon Musk stated that upgraded titanium grid fins were “super expensive” and unequivocally “the most important thing to recover.” SpaceX’s decision to expend Falcon 9 B1044 without even sparing the time to remove the booster’s recovery hardware and titanium fins demonstrates just how focused the company is on its customers’ needs. In the case of geostationary communications satellites like Hispasat 30W-6, launch delays on the order of a few days can cause millions of dollars of financial harm to the parent company – each day a satellite spends on the ground orbit is also a day with no revenue generation, a less-than-thrilling proposition to shareholders.

B1044 sadly lost any hope at a second flight, but the data SpaceX gathered from its uniquely fast reentry and attempted soft-landing will hopefully pave the way for the recovery of Falcon 9 and Heavy boosters after all but the heaviest satellite launches. GovSat-1, a launch that saw its flight-proven booster famously survive a similarly hot landing in the ocean, was the first largely successful test of this new and experimental method of more efficiently recovering Falcons. By igniting three of its nine Merlin 1D engines instead of the usual single engine while landing, Falcon boosters can theoretically reduce the amount of fuel needed to safely land, fuel savings that can then be used to push its payloads higher and faster. However, the downsides of this approach are several. With three times as many engines igniting at landing, the margin of error for a successful landing becomes downright miniscule – the tiniest of problems with ignition, throttle control, or guidance could cause the rocket to smash into the drone ship at considerable speed. Additionally, triple the landing thrust would subject the booster to as much as 10Gs of acceleration (10 times the force of Earth’s gravity), forces that would almost instantaneously cause the average human (and even specially trained fighter pilots) to black out.
This rocket was meant to test very high retrothrust landing in water so it didn’t hurt the droneship, but amazingly it has survived. We will try to tow it back to shore. pic.twitter.com/hipmgdnq16

Regardless of 1044’s untimely demise, another successful mission for SpaceX is purely positive. Happy customers make for a happy company, and SpaceX has achieved an incredible consistency of success in the last year alone. The loss of a new, potentially-reusable Falcon 9 booster is sad, but it only serves to foreshadow the imminent introduction of Falcon 9 Block 5, an upgrade hoped to realize Elon Musk’s decade-old dream of rockets that can be reused as many as 10 times with minimal refurbishment, and 100 times with maintenance. That debut could occur as early as April, just a month away.

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!
— Elon Musk (@elonmusk) October 15, 2026
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.

These aero features aren’t just for looks: they provide the best passive downforce package of any road car (approaching F1 levels!) with wing actuation driven by the @Tesla_Optimus actuator system https://t.co/AqrC4qUga9

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.
