SpaceX on track for biweekly launch cadence in the remainder of year
Weekly rapid reuse launches expected by 2019

Following a weekend of extraordinary accomplishments, seeing SpaceX flawlessly execute two missions – one with a reused first stage – in just over 48 hours of each other, the company has capitalized on a uniquely successful weekend and year and offered information about their future plans.
The launch of BulgariaSat-1 and Iridium-2 on Friday and Sunday respectively marked the eight and ninth launches of 2017 for SpaceX, and officials at the company are reportedly expecting to launch approximately 24 missions this year, meaning 15 more to come over the next 6 months. Given the recent demonstration of 48 hour launch cadence and a more regular schedule of biweekly launches in the past few months, an expectation of 15 more launches for 2017 lines up perfectly with a cadence of two launches a month from LC-39A Cape Canaveral and three Iridium launches from Vandenberg, which happens to be exactly what is currently manifested.
Originally manifested for up to 27 launches this year, successfully launching 24 missions, one of which might be the inaugural flight of Falcon Heavy, would be extraordinarily hard to ignore in an industry that has compared the launch industry to manufacturing beverage containers and argued that reuse is only sustainable with more than 20 launches a year on a company’s manifest.

SpaceX is now likely to undertake 24 launches this year, but the company also revealed this weekend that it intends to achieve a regular weekly launch cadence (52 launches per year) as soon as 2019. In a recent article, I speculated that we might begin to see regular weekly launches once both LC-39A and LC-40 were active, and that appears to be nearly correct. If SpaceX is to regularly conduct weekly launches by 2019, it is bound to begin shrinking its two week cadence as soon as is safe and possible. This will likely occur once Falcon Heavy has successfully flown several times from LC-39A, thus freeing SpaceX to deem the vehicle operational and less at risk of destroying one of their two Eastern pads.
There is also a tentative understanding that SpaceX is striving to construct and activate their planned Boca Chica, Texas launch complex by 2019. The successful reactivation of LC-40 and subsequent modification of LC-39A for Falcon Heavy will leave the brunt of SpaceX’s launch complex maintenance and construction teams free to focus entirely on the Texas facility sometime late this year or early next year, meaning that Boca Chica pad activation could certainly occur as early as 2019. This would leave the company with two fully operational all-purpose launch pads dedicated to Falcon 9 launches if they choose to retain LC-39A solely for Falcon Heavy and Commercial Crew launches, allowing them to reach weekly cadences even before the launches of Falcon Heavy, Commercial Crew contracts, and Vandenberg launches are accounted for.
One crucial factor playing into SpaceX’s ability to launch 52 times in a year is of course reusability, as it is hard to imagine SpaceX more than doubling their Falcon manufacturing capabilities in under a year and a half. Likely no coincidence, SpaceX simultaneously offered information to insurance underwriters about the increasing speed of their ability to launch, recover, and reuse first stages. More specifically, a spokesman of the company stated that the reuse of BulgariaSat-1’s Falcon 9 1029 took considerably less than half as long as the inaugural reuse of the stage that launched SES-10 earlier this year, implying that refurbishment and quality assurance checks for 1029 took something like four or five months total.
With SpaceX having debuted new titanium grid fins intended to speed up reuse on the Sunday launch of Iridium-2, the company is well on its way to transferring over to Block 4 (upgraded engine performance) and possibly Block 5 of Falcon 9 later this. Block 5 is expected to introduced major changes meant to replace aspects of the current Falcon 9 that require major refurbishment after recovery. Musk detailed these changes several months ago in a Reddit AMA (Ask Me Anything), mentioning that reusable heat shielding around the engines, improved landing legs, and titanium grid fins were the main aspects of a Block 5 of Falcon 9 meant to offer rapid reuse without refurbishment. In June 22nd interview on the Space Show, Gwynne Shotwell reiterated that this “final” version of Falcon 9 is expected to be able to launch, land, and relaunch with barely more than a thorough once-over, and ought to be capable of flying a dozen missions at least.

This final piece of the puzzle of weekly cadence fits in quite nicely. With a possible introduction date for Block 5 of late 2017 or early 2018, SpaceX will likely end production of Block 3 by the end of this year and transfer over entirely to the easily reusable Block 5. Assuming a continuing a trend of increasingly reuse-friendly customers, Hawthorne production capacity of approximately 20 Falcon 9s per year, and a plausibly significant reduction in launch costs due to more rapid and complete reuse, SpaceX could find themselves at the start of 2019 with a dozen or more launch vehicles that are each capable of conducting upwards of 10-12 highly affordable launches each.
Let there be no doubt: these are incredibly optimistic and difficult goals for the company to achieve on the timescale they have provided. However, given the number of beneficial changes likely to soon be made to both the launch vehicles and SpaceX’s manufacturing, launch, and refurbishment facilities in the next 6-12 months, those goals are realistically achievable, albeit with some likely delays. Regardless, things are beginning to get rather intense for SpaceX and for the launch industry in general.
Keep your eyes peeled for upcoming Teslarati coverage of SpaceX’s next July 4th launch and its static fire that is scheduled for as soon as this Thursday.

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.

Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds
Tesla’s Roadster comes in Performance, Thrust and Rocket versions, with a claimed 0-60 under 0.59 seconds.
Tesla finally showed the next generation Roadster on Thursday night, and the demo had more in common with a SpaceX test than a track lap. At an event outside Waco, Texas, near SpaceX’s McGregor site, the car used a mix of fans and cold gas thrusters to drive up a curved ramp until it was upside down, then flew off, flipped and landed on the pavement. “Well, it worked,” Elon Musk said. “Flying cars are real.”
The Roadster also hovered itself over a Cybercab, Cybertruck, Tesla Semi, Model Y and Model 3 while moving, and that Tesla showed it going 0 to 60 mph in one second. Musk said “this will be the actual car that’s on the roads” and that it “literally is just going to puff itself up” to perform the maneuvers whenever an owner wants. He called the result a collaboration between Tesla and SpaceX engineers that is “better than any James Bond car,” with Franz von Holzhausen and Lars Moravy on site.
Tesla published new mind-blowing stats for the car that replace the previous targets. The Performance version is road ready and seats two, with active aerodynamics and a multi-mode suction system, and Tesla lists 0 to 60 mph in under 1.6 seconds. The Thrust version is race ready, also seats two, and adds rear-mounted cold gas thrusters for a 0 to 60 time of under 0.9 seconds. The Rocket version is described as air ready, seats one, and uses perimeter-mounted thrusters for forward and upward acceleration plus lateral rotational movement.
| Configuration | Seats | 0 to 60 mph |
|---|---|---|
| Performance | 2 | under 1.6 s |
| Thrust | 2 | under 0.9 s |
| Rocket | 1 | under 0.59 s |
Tesla’s own description: “So…yes, it can fly.” It lists a 0 to 60 time of under 0.59 seconds for Rocket, a top speed of up to more than 230 mph, and range of more than 300 miles. Tesla has not yet given pricing in the information we have seen, but has reopened $50,000 reservations in the newly updated Tesla Roadster configurator. Production is planned for Giga Texas in 2027 or 2028, and Musk has said it would follow the demo by 12 to 18 months.
Every car on the road today is limited by one thing: tire grip
Roadster’s thruster system generates 4–5x the force the tires can.
More force on the same mass means significantly better acceleration – physics does the rest https://t.co/zdPRT2aKwZ

Tesla’s Roadster page adds more on how the car works. A multi-mode fan and ground sealing system pulls air from under the car, producing enough suction to hold it upside down even when stationary. Active wings, steer-by-wire with a yoke, and a Track Mode that lowers the car round out the driving setup. The cold gas thrusters use all-electric actuators for micro adjustments to stabilize the car in flight. Tesla says it cut weight with magnesium, titanium and carbon fiber, manual controls and a fixed seat position, and the exterior has hidden headlights, a full-length taillight and Ano White paint inspired by aerospace coatings. Inside are an Ultrawhite interior with gray microsuede, a center touchscreen and two smaller forward displays, and gold tinted glass modeled on spacesuit visors. Availability is tiered: Performance is by reservation, Thrust is a limited release, and Rocket is invite only. Tesla notes the car is not approved for public road use, and that Rocket is not available in all regions.

Musk has described the Roadster as “the best of the last of the human-driven cars,” and he has been open that it is a halo product. He said he is “not sure it moves the needle massively from a revenue standpoint,” and has warned that anyone whose top priority is safety should not buy it. Tesla reports third quarter earnings on October 21.

Amazon shuts out Elon Musk’s Grok Bot so he may just build his own rival store
Musk promises SpaceX will cover Grok Bot purchase errors, tells users to shop beyond Amazon.
Elon Musk said SpaceX will reimburse users if Grok Bot botches a purchase or leaks their card details. A few hours later he was telling users to take their shopping elsewhere after Amazon shut the agent out.
The first post was a reply to an X user who said Grok Bot booked him a flight after he sent a photo of his credit card. “This works well,” Musk wrote. “If Grok @Bot makes a mistake with a purchase or leaks your card (never happened yet), SpaceX will make you whole,” said Musk.
The second came after another user posted the error his Grok Bot hit on Amazon: “Continued access by an unauthorized AI agent violates Amazon’s Conditions of Use, to which our customers have agreed.” The user said his bots can no longer order from the site. Musk answered, “Just ask Grok @Bot to buy what you want someplace else and get a better deal. There are far more purchasing websites than just Amazon!” He later added, “Maybe we should start a competitor to Amazon,” a possible hint at an X shopping service.

The Amazon block did not start Thursday. A reply to Musk on October 10 said Amazon was blocking the bot, and Musk responded that Grok would find another way, then showed an order it placed on Lego’s website.
The latest reimbursement promise builds on late August when Musk told a Tesla investor weighing whether to give Grok Bot access to his bank accounts, “If Grok Bot messes up, we will make you whole,” as Teslarati covered when SpaceXAI added its Finance integration. That promise goes further than the company’s consumer terms, which make users responsible for what their agents do and generally cap liability at the greater of fees paid or $100. Neither Thursday post says those terms have changed, so for now it remains a statement on X rather than a published policy.
The two posts matter to Tesla owners because Grok Bot is no longer limited to a phone. Tesla brought it into its vehicles on September 22, and it is now enabled across every Cybercab and the rest of the Model Y Robotaxi fleet, as noted when Teslarati looked at why Grok Bot may be the Cybercab’s real advantage. A rider who asks for groceries or a coffee order is relying on retailers that let the agent in. Amazon has now said it will not, and Musk’s answer is to route around it.
Amazon has not commented publicly on the block in the posts Teslarati reviewed, and it is unclear whether Musk will follow through on a rival store.
So, how many of you do the vast majority of shopping on Amazon and hate that you do? Comment and let us know your thoughts!
