SpaceX wraps up a decade of reusable rocketry with fastest booster recovery yet
SpaceX has completed its 13th and final launch and landing of the year and decade, marked by a Falcon 9 booster’s successful return to Port Canaveral and subsequent processing to prepare it for another orbital-class mission.
Over the course of that recovery, SpaceX broke the record for the fastest Falcon 9 processing by several hours, a small but significant step towards the company’s ultimate goal of launching and landing the same Falcon 9 booster in less than 24 hours. Additionally, SpaceX appears to have finished processing booster B1056 on December 21st, the 4th anniversary of Falcon 9’s first successful landing after an orbital-class launch.
Since that first success on December 21st, 2015, SpaceX has rapidly moved through several distinct iterations of Falcon hardware, constantly improving components, systems, and the overall fit, finish, and reliability of the rocket. Over the last four years, SpaceX has landed an incredible 47 Falcon 9 and Falcon Heavy boosters as part of 60 orbital-class launches, while the company recently launched Falcon 9 B1048 for the fourth time and flew the same two Falcon Heavy boosters in April and June. Ultimately, 2019 has been a spectacularly successful year for SpaceX, and – by the numbers – 2020 is set to be several times more ambitious, still.
On December 20th, less than a day after arriving in Port Canaveral, SpaceX technicians began the process of retracting Falcon 9 booster B1056’s four deployed landing legs. As it turns out, B1056 – returning to port for the second time after its third launch – became the first Falcon 9 booster to have all of its landing legs successfully (and semi-permanently) retracted in May 2019. To accomplish the feat, SpaceX designed a custom retraction mechanism that simultaneously serves as the crane jig used to lift the booster while vertical.
“The crux of the need for a relatively complex crane-and-jig method of leg retraction rests on SpaceX’s landing leg design. Put simply, after rapidly deploying with a combination of gravity and hydraulics, Falcon 9 landing legs have no built-in way to return to their stowed state. Each of the four legs are quite large, weighing around 600 kg (1300 lb) and stretching about 10m (33 ft) from hinge to tip. They use an intricate telescoping carbon fiber deployment mechanism to give them legs enough strength to stand up to the stresses of Falcon 9 booster landings.
Combined, the legs’ size and telescoping mechanism makes the addition of an onboard retraction mechanism impractical. All the needed hardware would struggle to find a good place for installation and would quite literally be dead weight during launches and landings, stealing from Falcon 9/Heavy payload capacity and generally serving no purpose until a booster has been lifted off the ground with a giant crane.”
Teslarati — May 7th, 2019
Impressively, SpaceX took less than an hour and a half to successfully retract all four of thrice-flown Falcon 9 B1056’s also thrice-flown landing legs. Less than three hours after the rocket’s legs were snugly retracted, SpaceX immediately attached a second crane and brought the booster horizontal. Altogether, this made Falcon 9 B1056’s third recovery the fastest SpaceX has ever performed by 3-6 hours – seemingly small progress but still no mean feat.
SpaceX’s fastest-ever Falcon 9 recovery – from the drone ship berthing to the booster departing the port on a transporter – occurred with B1049 after its third launch and landing, taking just 2.01 days (48.25 hours). Falcon 9 B1056’s third recovery appears to have beaten that record by at least several hours, brought horizontal and installed on a SpaceX transporter perhaps less than 1.75 days (42 hours) after arriving in port – more than 10% faster than B1049’s previous record.
Meanwhile, SpaceX lifted a fairing half recovered off the surface of the Atlantic Ocean by GO Ms. Tree, appearing unharmed after having potentially been dropped when the ship’s secondary (fairing) fishing net tore while moving the Falcon 9 hardware.
With any luck, that fairing half will be in good enough shape to be reused on a future Starlink mission, seemingly unlikely but proven to be well within the realm of possibility after SpaceX’s very first fairing reuse involved two halves recovered off the ocean surface after Falcon Heavy Block 5’s April 2019 debut. B1056, however, is all but guaranteed to fly again – this time on its fourth launch – in the near future. SpaceX has dozens of launches planned in 2020, so there will be plenty of opportunities.

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.
