SpaceX to demonstrate weekly launch cadence: 3 launches in 14 days

SpaceX is in the process of preparing to launch BulgariaSat-1, with the first attempt scheduled for Saturday, June 17th between 2:10 p.m and 4:10 p.m. EST. BulgariaSat-1 will be Bulgaria’s second satellite ever and will act as a telecommunications hub in geostationary orbit, around 30,000 miles above Earth.

Following a highly successful launch and docking of the eleventh cargo mission of its Dragon spacecraft, Launch Complex 39A has since undergone routine checks to verify its condition and has likely been lightly repaired. The static fire for the upcoming mission is scheduled as early as tomorrow. Both the static fire and launch were pushed back two days due to a 48 hour delay of the CRS-11 launch.

The launch of BulgariaSat-1 is already exceptional for several reasons. First and foremost, the Falcon 9 first stage to be used in the upcoming mission has already flown once before, assisting in the successful launch of Iridium’s first ten NEXT satellites in early January of this year. It will thus mark the second time SpaceX has truly reused a Falcon 9 first stage. There has even been a bit of circumstantial evidence that the choice to launch on a recovered F9 resulted in BulgariaSat-1 being moved ahead of Intelsat 35e, which is now scheduled for no earlier than July 1st. Regardless, another successful reuse will be a boon for a SpaceX in the throes of an unprecedentedly busy year of launches by once again demonstrating the viability of their program of reuse and thus hopefully swaying more customers to take the leap to reused rocket cores.

The second reason, as touched on above, is that BulgariaSat-1 will mark the beginning of a two week period in which SpaceX could potentially conduct three separate launches, two at Cape Canaveral and one at Vandenberg Air Force Base. If successful, this would demonstrate weekly single-vehicle launch cadence, something that has not been seen in the launch industry in quite some time. This weekly cadence, if successful, will demonstrate a maturing company that is truly preparing for extraordinary launch cadence. By using two pads, one in California and one in Florida, SpaceX will still be able to provide two weeks between launches in order to prepare each launch site for the next launch, while effectively launching once a week. While Vandenberg Air Force Base can only support polar orbit launches, LC-40 is currently deep into the process of being repaired and reactivated following the failure of a Falcon 9 late last year.

With LC-40 preparing for reactivation sometime in August or September, SpaceX will find themselves at long last with two viable all-purpose launch pads in very close proximity to each other. By staggering launches on each pad and continuing to maintain the two week pad turnaround time after launches, SpaceX could theoretically begin to sustain regular weekly launches as few as three months from now. A successful weekly cadence this month could reinforce that such a sequence of events is a possibility.

SpaceX has long been working to rapidly increase its ability to launch frequently, and this year has been an exceptional example of several pieces fitting together. The company has begun to use an automated flight termination system, which will allow them to rely less upon the availability of Cape Canaveral’s Range Officers while crafting their manifest and launch schedules. Normally, the flight termination system in rockets is monitored by an actual team of people who have barely a few seconds to decide if rocket telemetry is less than nominal and prevent what is effectively a large missile from impacting populated areas. SpaceX has replaced this with an arguably much safer approach dependent upon their mature autonomous avionics systems, simply meaning that computers on board their rockets and spacecraft automatically analyze telemetry and control vehicle performance and guidance. SpaceX has been testing this system in a way that is almost identical to Tesla’s method of installing inert autonomy software that can learn without actually controlling the vehicle, and it is consequently only now being implemented after SpaceX and the Air Force have a high degree of confidence that it will outperform its human colleagues.

The ultimate goal of this automated flight termination system (AFTS), as well as many other significant changes to both the hardware of pads and vehicles, is to eventually allow SpaceX to accomplish Elon Musk’s long fabled and oft-ridiculed goal of 24-hour reusability, and thus 24-hour launch cadence. SpaceX and the USAF have both stated that AFTS alone will likely allow Cape Canaveral to support up to 48 launches a year. While shared between ULA and SpaceX, even 36 launches a year would effectively leave SpaceX with a shrinking launch manifest and significantly increased revenue and profit. This would speculatively allow them to more rapidly develop their pursuits of Mars, a vast constellation of broadband satellites, and more.

Nevertheless, this is all of course speculation and dependent upon many things going well. If SpaceX is able to successfully launch BulgariaSat-1 on June 17th, Iridium NEXT 2 on the 25th, and Intelsat 35e on July 1st, they will have successfully demonstrated the ability to support a weekly launch cadence and will have to do little more than wait for the availability of a second East coast pad to begin to take full advantage of it.

With ten launches scheduled between now and October and ten more launches scheduled between October and the end of December, it is guaranteed to be one incredible year for SpaceX and their fans.

SpaceX readies Starship Flight 14 for a historic journey into uncharted territory

SpaceX finished Starship’s Flight 14 rehearsal, clearing the way for its first orbital flight Monday.

SpaceX has cleared one of the last hurdles before Starship’s first trip to orbit. The company posted on X Thursday afternoon that its launch rehearsal for Flight 14 was complete, keeping the mission on track for Monday, September 28. The launch window opens at 7:15 a.m. CT at Starbase, Texas, and runs for 75 minutes.

A wet dress rehearsal is essentially launch day without the launch. Crews fill Booster 21 and Ship 41 with thousands of tons of extremely cold propellant, run the countdown nearly to ignition, then drain everything back out. It lets engineers catch leaks or equipment problems before anything leaves the pad. SpaceX still needs a launch license from the FAA before the stack, which stands 407 feet tall, can fly.

Flight 14 matters because of where it is going. All 13 previous Starship flights followed a suborbital path, which works like throwing a ball extremely high and far: the vehicle reaches space, but it is always on a course that brings it back down within about an hour. This time, Ship 41 will perform a short engine firing called an orbital insertion burn roughly 25 minutes after liftoff, giving it enough speed to keep falling around Earth instead of back into it. SpaceX plans about six laps at an altitude near 275 kilometers (171 miles) over nearly 10 hours, as Teslarati detailed when the mission was first announced.


Getting into orbit also means Starship has to prove it can get back out. The ship must relight a single Raptor engine in space to slow down for reentry. SpaceX says it will only attempt the orbital insertion burn after flight controllers confirm the hardware needed for that return burn has enough backup, and its flight plan includes health checks that could shorten the mission to two or five orbits.

Flight 14 is also the first to put working satellites into service. Flight 13 carried 20 Starlink V3 satellites in July, but they came back down with the ship because that mission never reached orbit. This time, 26 V3 satellites are meant to stay up and join the constellation within a few weeks. Together they add about 26 terabits per second of network capacity, which SpaceX says is roughly 10 times what a single Falcon 9 launch of older V2 Mini satellites adds. Three of them carry cameras that will photograph Starship’s heat shield in orbit to check for tile damage before reentry.

The hardware has changed too. Ship 41 flies with extra fasteners on tiles in the most vulnerable areas, fixes for gaps where superheated plasma slipped behind tiles, and curved tiles designed to reduce heating between them. Two tiles recovered from Ship 40 will fly again, the first reuse of any part of a Starship heat shield. Booster 21 carries better engine filtering and new relight software after ice clogged three center engines on the previous booster, leaving only eight of 13 engines to restart for its landing burn.

Ship 41 is targeting a splashdown in the Pacific Ocean west of Chile, a new recovery zone after several Indian Ocean landings, while Booster 21 aims for the Gulf. Neither will be caught by the tower on this flight. Elon Musk said in August that a ship catch was likely “in a few months.”

Google just picked SpaceX for its first step into orbital AI

Google will launch its first Project Suncatcher AI satellite on SpaceX’s Transporter-18 rideshare next week.

Google is about to put its own AI chips into orbit for the first time, and it is paying SpaceX to get them there.

The company said Thursday that the first in-orbit test of Project Suncatcher, its research effort to find out whether space can host large-scale AI computing, will fly next week on SpaceX’s Transporter-18 rideshare mission.

The satellite, called MVP, is about the size of a refrigerator and carries four of Google’s Tensor Processing Units, the same chips Google runs in its ground data centers. Google originally planned to launch two custom satellites in 2027, but chose to move faster by integrating its chips into a satellite.

MVP’s solar panels supply about one kilowatt of power, and Google will run Gemini models on the TPUs only in bursts of roughly 15 minutes before the chips shut down so the radiators can shed heat. In a blog post, Google said its Trillium TPUs survived vibration testing that mimicked sustained launch loads of up to 10g, with individual components seeing 50 to 100g, and handled a radiation dose greater than a five year mission would deliver.

SpaceX and Google mull massive partnership on Musk’s orbital data dream: report

Next week’s flight, slated for October 1, follows a relationship that became public in May, when Teslarati reported that Google was in talks with SpaceX for a launch deal tied to orbital data centers. Google also holds a stake of roughly 6% in SpaceX.

The two companies are chasing the same idea from very different starting points. SpaceX’s own orbital compute program is built around the AI1 satellite, a roughly 70 meter structure derived from Starlink V3 hardware that is designed for 150 kW of peak compute, about 150 times the power MVP will draw. Elon Musk has brushed off concerns about crowding orbit with those satellites, and SpaceX is building its Gigasat factory in Bastrop, Texas, to produce them, targeting an annualized rate of about 1 GW of space compute by the end of 2027.

Musk also posted on X on Thursday that “the amount of compute in space will obviously round up to 100% of all compute.”

Google has been more cautious in public. Its research estimates that launch prices need to fall below about $200 per kilogram before an orbital data center can compete with a ground facility on energy cost, a threshold the company believes could be reached around the mid 2030s. The Suncatcher team has said it expects the effort to remain a project rather than a product for years, which leaves the first real test of its hardware riding on a rocket from the company with the most aggressive timeline in the field.

Tesla Cybercab gets initial tie-in to localized, in-house cathode plant

Published

Tesla has taken another concrete step toward owning its battery supply chain, and it’s doing so with what is perhaps the most important vehicle in its short-but-storied history.

On September 23, Tesla announced that it has officially built the first Cybercab with cathode material produced in-house at the company’s first cathode plant in the U.S., and the first in the U.S. overall.

Active cathode material is the most expensive piece of a lithium-ion battery cell, and it often accounts for more than a third of cell cost. For years, the industry sourced a majority of it from Asia, but Tesla’s decision to make it in the United States bodes well for the Cybercab project. This is the latest chapter in Tesla’s vertical integration strategy, which began in public at Battery Day in 2020.

At the Battery Day Event, Elon Musk said the company would build a North American cathode plant and overhaul the process to cut costs and waste, while also making some of the most powerful and long-lasting cells in the industry.

The Austin facility took years to appear. Tesla filed permits for “Project Cathode” in 2022 on land near Giga Texas. By mid-2022, the building frame was up and Tesla later invested hundreds of millions of dollars as part of a larger expansion of the Giga Texas plant. The company stated it was operating the first large-scale cathode production facility in North America to supplement 4680 cell production.

One month later, that material reached a finished Cybercab.

The timing of this breakthrough is monumental for the Cybercab program. As Tesla officially launched the first Cybercab rides to the public earlier this month, production of the ride-hailing-geared vehicle is moving forward on the planned S-curve that CEO Elon Musk told everyone to expect.

Nevertheless, packs of Cybercab units have been spotted throughout the United States, in an effort to potentially activate the fleet as soon as the company gains regulatory approval in various geographic areas.

On top of that, Tesla owning the cathode step and pairing it with its own in-house lithium from the Gulf Coast refinery shortens the supply chain that once stretched thousands of miles and subjects every pack to fewer external price shocks and geopolitical risks.

Tesla is not yet independent of all of its foreign suppliers, as some precursor metals come from mines and chemical plants. But the first in-house cathode Cybercab shows the company is closing the most expensive and most concentrated gap in its battery production efforts. For a vehicle like Cybercab to operate at a high utilization within the Robotaxi network, that control over cost is so crucial.

It is arguably as important as the software that drives it.
