SpaceX Starlink launch suffers last-second scrub, ULA up next [update: double scrub]
Update: ULA has scrubbed today’s NROL-44 launch attempt after the weather at the launch site substantially worsened. The Delta IV Heavy rocket’s next shot at launch is now scheduled no earlier than 11:58 pm EDT (03:58 UTC), Tuesday, September 29th, just two hours after a SpaceX Falcon 9 is scheduled to launch the US military’s fourth upgraded GPS III satellite.
SpaceX’s eleventh Starlink launch of the year was scrubbed ~30 seconds before liftoff by bad weather, likely delaying the mission a few days and leaving ULA’s latest Delta IV Heavy launch attempt next in line.
Scheduled to lift off at 10:22 am EDT on Monday, September 28th, SpaceX’s 12th operational Starlink launch (V1 L12) nearly made it to liftoff before the company called the mission off, prioritizing mission success above all else. Given that SpaceX’s Starlink program puts the company in the unique position of being its own launch customer, the decision to let a relatively mild weather violation delay a Starlink mission by at least a few days is unintuitively encouraging.
It’s no secret that SpaceX has become the most successful private launch company in history and a commercial force to be reckoned with, handily overtaking United Launch Alliance (ULA) and Arianespace to acquire a vast majority of the commercial launch market share. Falcon 9 is on track to become the fastest commercial rocket in history to cross the 100-launch milestone and SpaceX is already well on its way to regularly out-launching entire countries with 20+ missions per year. The single biggest risk facing the company is arguably complacency and an infamous tendency known as “launch fever.”

At the cutting edge of spaceflight, constant, exhaustive vigilance is ultimately the only thing standing between a reliable rocket or spacecraft and catastrophic failure. Perhaps the single biggest threat to that vigilance is the somewhat understandable desire to avoid launch delays – a fact of life for rocketry that nevertheless costs time, money, and (to some) reputation. The term “launch” or “go fever” was originally colloquialized to describe the irresponsible managerial pressure to launch largely responsible for both of NASA’s catastrophic Space Shuttle failures.
Some (if not most) parts of SpaceX almost assuredly would rather avoid launch delays. The fact that the company continues to accept Starlink launch delays and respect Falcon 9’s limits strongly implies that SpaceX has found ways to prevent launch fever while still pushing the envelope of launch cadence and rocket reuse. Starlink-12, for example, was originally meant to launch on September 17th but was delayed ~10 days by strong ocean currents before being scrubbed seconds before launch on September 28th. Combined with the fact that SpaceX is technically free to accept more risk on its own Starlink launches, compounded delays will inevitably test the limits of any organization’s resolve.

While the argument that SpaceX is technically the only direct stakeholder in Starlink missions is a bad-faith argument that could easily be made to push for increased risk tolerance, it’s only true in a vacuum. A Falcon 9 failure during a Starlink launch would still have major consequences for all of SpaceX’s customers, particularly delaying critical NASA astronaut and US military launches until a lengthy accident investigation is completed. SpaceX executives and managers involved in launch go/no-go decisions clearly understand this and act accordingly.
Starlink-12 will likely be recycled for another launch attempt sometime after ULA’s next Delta IV Heavy launch attempt and probably after SpaceX’s own GPS III SV04 mission for the US military, scheduled no earlier than (NET) 12:02 am EDT (04:02 UTC) and 9:55 pm EDT (01:55 UTC), September 29th, respectively.

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.
