SpaceX drone ship heads to sea for record-breaking Starlink launch

SpaceX’s newest drone ship is on its way out into the Atlantic Ocean for a Starlink mission that will break the company’s record for annual launch cadence.

Somewhat confusing known as Starlink Shell 4 Launch 3 or Starlink 4-3, the batch of 53 laser-linked V1.5 satellites is scheduled to fly before Starlink 4-2 for unknown reasons and at the same time as Starlink 2-3 is scheduled to fly before Starlink 2-2 on the West Coast. Regardless of the seemingly unstable launch order, perhaps related to the recent introduction of Starlink’s new V1.5 satellite design, drone ship A Shortfall of Gravitas’ (ASOG) November 27th Port Canaveral confirms that SpaceX is more or less on track to launch Starlink 4-3 no earlier than (NET) 6:20 pm EST (23:20 UTC) on Wednesday, December 1st.

In a bit of a return to stride after launching 20 times in the first six months but only three times in the entire third quarter of 2021, Starlink 4-3 is currently the first of four or even five SpaceX launches scheduled in the last month of the year. Nevertheless, if Starlink 4-3 is successful, it will also set SpaceX up to cross a milestone unprecedented in the history of satellite launches.

Specifically, Starlink 4-3 is SpaceX’s 16th dedicated Starlink launch of 2021 and will mark 951 Starlink satellites safely delivered to orbit since January 20th. If, as CEO Elon Musk has telegraphed is the plan, SpaceX intends to complete one more dedicated Starlink launch in December (either Starlink 2-2 or 2-3), the company could round out 2021 having launched more than a thousand satellites in a single year.

Thanks to Starlink, 2020 was the first year in history in which more than a thousand satellites (technically 1283) were launched into orbit. Now, in 2021, there’s a good chance that SpaceX Starlink launches alone will account for more than a thousand satellites launched in one year. Altogether, SpaceX will likely end the year having singlehandedly launched a total of more than 1240 satellites in 2021 – and despite only completing 3-4 Starlink launches in the last seven months of the year compared to 13 in the first five months.

For SpaceX and Starlink, that’s great news. In March and November 2018, the FCC approved two SpaceX applications to launch and operate constellations of ~4400 and ~7500 Starlink satellites – a total of around 11,900 satellites. To avoid having its licenses revoked, SpaceX – like all other FCC constellation applicants – is required to launch half of its licensed constellation within six years of its license receipts and full constellation within nine years. For SpaceX, that means it has to launch at least ~2200 satellites operating around 550 km (340 mi) and ~3750 satellites operating around 350 km (~220 mi) by March and November 2024, respectively.

With a bit less than 1700 Starlink satellites currently functioning in orbit, even if SpaceX merely repeats its 2021 cadence, it will be on track to outright finish Starlink’s first 4400-satellite phase by mid-2024 and should easily cross the halfway mark by mid-2022 – years ahead of schedule for both. However, simultaneously hitting Starlink’s very low Earth orbit (VLEO) deployment milestones will still be a massive challenge. Given that SpaceX has yet to launch a single VLEO Starlink spacecraft three years after license approval, it now has less than three years to launch ~3750 VLEO satellites on top of at least 500 more LEO satellites.

If SpaceX can replicate its H1 2021 Starlink launch cadence throughout 2022, completing at least 26 launches in 52 weeks, it may actually have a shot at pulling off a cadence close to what is needed to meet its FCC deployment requirements (an average of 1400 satellites per year for the next three years). If SpaceX simply aims for the average annual numbers needed to complete the full ~11,900-satellite Starlink constellation by November 2027, it will need to launch around 1800-2000 satellites per year – equivalent to 35-40 Falcon 9 rockets.

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.

Published

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.



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.

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.


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.
