Published as part of an August 2019 environmental assessment (EA) draft for Starship’s prospective Pad 39A launch facilities, SpaceX revealed plans for a truly mindboggling number of annual Falcon 9 and Falcon Heavy launches by 2024.

As environmental planning documents, the figures should be taken with a large grain of salt and be treated as near-absolute ceilings rather than practical goals. Nevertheless, SpaceX revealed plans for its two Florida launch sites (LC-40 and LC-39A) to ultimately support as many as 70 annual launches of Falcon 9 and Heavy by 2024, less than five years from now.

Simply put, even the most dogmatic fan would have to balk at least a little bit at the numbers SpaceX suggested in its Starship EA draft. More specifically, SpaceX apparently has plans to support as many as 20 annual Falcon 9/Heavy launches from Pad 39A and an incredible 50 annual Falcon 9 launches from LC-40 as early as 2024.

“SpaceX plans to increase the Falcon launch frequency to 20 launches per year from LC-39A and up to 50 launches per year from LC-40 by the year 2024. However, as Starship/Super Heavy launches gradually increase to 24 launches per year, the number of launches of the Falcon would decrease.“

Two obvious options

Given just how significant of an increase a 70-launch annual cadence would be for SpaceX relative to their current record of 21 launches, it’s entirely possible that these numbers are really just a pipe dream included in a pending environmental assessment to hedge bets just in case a similar launch frequency is achieved over the next five years.

On the other hand, it’s possible that SpaceX – just now coming into the ability to reliably achieve a much higher cadence – has coincidentally become payload-constrained at almost the same time, meaning that the company’s customers’ payloads just aren’t ready for launch. This would explain, for example, why SpaceX has only launched 10 times this year when the company had already completed 15 launches by August 2018.

Additionally, it can be almost unequivocally assumed that all but 15-20 of those supposed 70 annual launches would come from SpaceX’s own internal demand for Starlink launch capacity. Assuming no improvements between now and 2024, 50 Falcon 9 launches could place as many as 3000 Starlink satellites in orbit in a single year, equivalent to more than 25% of the entire proposed ~11,800-satellite constellation.

Barring regulatory changes to US Federal Communications Commission (FCC) and International Telecommunication Union (ITU) requirements, SpaceX must launch at least half of all Starlink satellites (~5900) by November 2024 and finish launching the remaining ~5900 by November 2027. If SpaceX fails to reach those deployment milestones, the company runs the risk of losing Starlink’s domestic and international licenses to operate.

This would help to explain why SpaceX says that it’s planning to reach a maximum cadence of 70 annual launches “by 2024”, given that 2024 will be a pivotal year in the eyes of regulations currently in effect for Starlink.

Starship confusion

As noted in the quote above, SpaceX plans to eventually phase out Falcon 9 and Heavy launches as the company’s next-generation Starship and Super Heavy launch vehicle gradually comes online, proves itself reliable, and begins operational launch activities. According to SpaceX, given just how much mass Starship can nominally launch relative to both Falcon 9 and Heavy, far fewer launches will be needed to accomplish the tasks that would otherwise require several times more launches of SpaceX’s smaller vehicles.

SpaceX’s initial Environmental Assessment for Starship launches from Pad 39A caps the rocket’s maximum cadence at 24 annual launches. Oddly, this directly contradicts the goals set for Starship (formerly BFR) by CEO Elon Musk and SpaceX more generally. By building a launch vehicle that is fully and rapidly reusable, the goal has long been to deliver cheap, aircraft-like access to orbit at a completely unprecedented scale.

This would technically mean that SpaceX could actually dramatically increase its launch cadence without increasing costs, allowing the company to perform currently nonsensical missions where Starship might launch payloads weighing just 5-10% of its total payload capacity. Airline operations routinely do things of a similar nature, sometimes flying just a fraction of their maximum passenger load to destinations for a variety of reasons.

Additionally, SpaceX has consistently indicated that Starship will rely heavily on orbital refueling to accomplish its ultimate deep space ambitions. Previous presentations from Elon Musk have shown that launches to the Mars or Moon with significant payload would require no fewer than five separate tanker launches and orbital refuelings, all of which would classify as one of the 24 annual launches SpaceX has described in its August 2019 EA draft. On their own, launching two Starships to Mars with 100 tons of payload each would require no fewer than 10-12 launches.

Ultimately, it’s unwise to draw any substantial conclusions from an Environmental Assessment like the one the above information has been taken from. This 39A-specific EA also ignores the possibility of a similar launch facility being developed in Boca Chica, Texas, which SpaceX explicitly acknowledges.

This particular draft is also the first Starship-related EA ever filed by SpaceX, and the company may thus be treating it more as a bare minimum with the intention of eventually pursuing far more ambitious launch rates once Starship has been established.

Elon Musk drops a Thanksgiving hint about Starship’s biggest test yet

Elon Musk says Starship Flight 15 will try to catch the ship itself, a first.

Published

Elon Musk says SpaceX’s next Starship flight will try something nobody has done before, by catching the ship itself. Speaking to roughly 2,000 people at the X Takeover event at Giga Texas on Saturday, Musk said Flight 15 is about four to six weeks away and “probably launches a little bit before Thanksgiving, is my guess.”

That is a slip from earlier reporting, which had pointed to a launch as early as October 19. Musk explained why the date keeps moving. “We’re making a bunch of improvements to the rocket between every flight,” he said, adding that there are often hundreds, sometimes thousands, of small changes. This time the list is short, “but some of them take a fair bit of work and we’ve got to go inside the tank to make some of these changes.”

“We’re going to try to catch the ship, which is a super big deal,” Musk said. “If we do so, that’ll be the first time that there’s been full recovery of an orbital class rocket.” SpaceX has already caught the Super Heavy booster with the tower’s mechanical arms, and has talked about catching the ship since late 2025, but the upper stage has never been caught.

Musk also laid out what comes after. “The next big milestone would be to refly both the booster and the ship,” he said, describing a Flight 16 where “all parts of an orbital rocket are reflown.”

The reason SpaceX wants this comes down to cost and cadence. Every Starship ship so far has ended its flight in the ocean, and SpaceX expects most of those water landings to end in fireballs. A ship that returns to Starbase intact can be inspected and flown again. SpaceX’s IPO filing, says Starship V3 is designed to deliver 100 metric tons to orbit in a fully reusable configuration, that SpaceX aims to cut the cost to reach orbit by 99% or more versus the historical average, and that tower catches should allow “multiple launches per day.”

The payoff goes beyond cheaper launches. The next generation Starlink V3 satellites are too large for Falcon 9 and can only fly on Starship, which can carry up to 60 per flight. Flight 14 on September 28 deployed the first 26 of them after Starship reached orbit despite an early engine shutdown, as Teslarati reported. Musk blamed engine computer software, and said the heat shield “was extremely robust,” which he claimed in August had solved Starship’s biggest challenge.

NASA’s Moon plans depend on the same capability. NASA’s inspector general has described a lander mission that needs a propellant depot in low Earth orbit and more than 10 tanker flights, with SpaceX targeting one tanker launch every six days. That schedule only works if ships and boosters come back fast and fly again. Also, ship to ship propellant transfer has not been attempted yet.

One interesting hurdle yet to be explored is bringing the ship back to the launch site, with reentry over land, which will undoubtedly come with a lot of aviation safety reviews.

Tesla’s mirrorless Cybercab will give riders a visibility upgrade

Tesla engineer confirms Cybercab update letting riders pull up rear and repeater cameras on demand.

Tesla is working on a Cybercab update that would let passengers pull up the vehicle’s rear and side cameras on demand, and the request came straight from a rider.

The exchange played out on X late Friday. Cybercab rider Dan Burkland shared photos of the two-seater’s cabin screen after an evening ride, praised the UI team’s work, and left one request: let riders open the rear and repeater cameras whenever they want, “especially for peace of mind.” Tesla UI software engineer Evan (@CarCoder) answered with two words: “In development.”

The idea fits a pattern Teslarati has tracked since public rides began. Days after paid Cybercab service opened in Austin, Tesla sent riders a survey that asked them to rate the touchscreen, the app and the cabin, and to pick the features they wanted most. We reported on that survey in September, and a camera view is the kind of small software change Tesla can push quickly if riders keep asking.

It also speaks to something unique about the vehicle. With no steering wheel, no pedals and no driver, passengers have no mirror to check and no way to see behind them. The hardware is clearly built for camera awareness, from the repeater cameras to the rear camera. Letting a passenger look through those same cameras would give a nervous first time rider a way to confirm what is around the car.

The timing matters because the fleet is growing fast. Tesla’s Robotaxi account said on Saturday that more than 300 Cybercabs are now serving Austin, an eightfold increase in 30 days, and Tesla AI chief Ashok Elluswamy named Dallas as the next city. More cars and more cities mean more people riding in a driverless vehicle for the first time, which is exactly when small trust features carry weight.

For now, the feature is confirmed only as in development. If Tesla follows its usual pattern with Cybercab software, riders could see it appear in a point release without any announcement, and Teslarati will watch for it.

Tesla’s Cybercab fleet jumped 8x in a month, with Dallas up next

Tesla confirms its first official Cybercab fleet number as Austin scales fast and Dallas looms.

Tesla says more than 300 Cybercabs are now serving Austin, the first time the company has put an official number on its active Cybercab fleet. The figure came from the Robotaxi account on X on Saturday, which wrote that one month after launch the service had “scaled to 300+ Cybercabs serving Austin – an 8x increase in 30 days.”

Ashok Elluswamy, Tesla’s head of AI software, quoted the post with a line that carried the bigger news. “Two years since the 10/10 Cybercab WeRobot event, the cabs are everywhere in Austin now. Dallas soon,” he wrote. It is the first time Tesla has named the next city for public Cybercab rides.

Tesla opened Cybercab rides to the public in Austin on September 4, as Teslarati reported, a day after an invite only launch event. The ramp since then has been steep. Our September 28 report had the fleet at well over 100 units after availability jumped from 58 to 125 in a single week. On Thursday, Tesla added 150 Cybercabs to the Texas automated vehicle registry, lifting its registered count to 319 from 169. The first seven appeared on the registry on August 31.

RobotaxiTracker, a community site that counts vehicles from sightings and state records, listed 275 vehicles in unsupervised service in Austin on Saturday, 105 of them Cybercabs, which is well below Tesla’s figure. Tracker counts can lag official numbers, though Sawyer Merritt noted that Cybercab wait times in Austin stayed short on Saturday evening even with more than 2,000 fans in town for X Takeover.

Regulators are watching the rollout. NHTSA opened an audit query into Tesla’s certification that the Cybercab meets federal safety standards, and sworn answers are due October 30. Tesla reports third quarter earnings on October 21, which gives the company a natural venue to define its fleet numbers and put a date on Dallas.
