SpaceX President updates schedule for Starship’s orbital launch debut

Published

on

SpaceX COO and President Gwynne Shotwell says that the company now expects Starbase to be ready for Starship’s first orbital launch attempt as early as June or July, pushing the schedule back another month or two.

To accomplish that feat, SpaceX will need to more or less ace a wide range of challenging and unproven tests and pass a series of exhaustive bureaucratic reviews, significantly increasing the odds that Starship’s orbital launch debut is actually closer to 3-6 months away. While SpaceX could technically pull off a miracle or even attempt to launch hardware that has only been partially tested, even the most optimistic of hypothetical scenarios are still contingent upon things largely outside of the company’s control.

Will FAA or won’t FAA?

Both revolve around the Federal Aviation Administration (FAA), which – in SpaceX’s case – is responsible for completing a ‘programmatic environmental assessment’ (PEA) of orbital Starship launches out of Boca Chica, Texas and issuing a launch license for the largest and most powerful rocket ever built. In some ways, both tasks are unprecedented, but the bureaucratic processes involved are still largely the same as those SpaceX has successfully navigated over the last two decades.

First up, the FAA’s environmental review. Until very recently, the fate of Starbase’s PEA was almost completely indeterminable and could have gone any number of ways – most of which would not be favorable for SpaceX. However, just a few days ago and about a week after the FAA’s latest one-to-two-month PEA delay announcement, the agency updated an online dashboard to show that the fourth of five main PEA processes had been completed successfully. The most important part of the update is the implication that SpaceX and the FAA have now completed almost every aspect of the PEA that requires cooperation with other federal agencies and local stakeholders.

Only one more cooperative process – ensuring “Section 4(f)” compliance – still needs to be completed. Without delving into the details, there is no convincing evidence to suggest that that particular step will be a showstopper, though SpaceX might have to compromise on certain aspects of Starbase operations to complete it. Once Section 4(f) is behind them, the only thing standing between the FAA and SpaceX and a Final PEA is the completion and approval of all relevant paperwork. In other words, for the first time ever, the FAA’s targeted completion date – currently May 31st, 2022 – may actually be achievable.

Still, as the FAA itself loves to repeatedly point out, “the completion of the PEA will not guarantee that the FAA will issue a launch license – SpaceX’s application must also meet FAA safety, risk, and financial responsibility requirements.” Even if the PEA is perfect, SpaceX still has to secure an FAA launch license for the largest and most powerful rocket in history. It’s unclear if SpaceX and the FAA have already begun that painful back-and-forth or if some tedious fine print prevents it from starting before an environmental review is in place. Without knowing more, launch licensing could take anywhere from a few days to several months.

A series of tubes

Without the FAA’s launch license and environmental approval, any Starship SpaceX builds cannot legally launch from Starbase. On the other side of the coin, though, it’s just as true that the FAA’s nods of approval are worth about as much as the paper they’re written on without a rocket that’s ready to launch. In a perfect world, SpaceX would have a Starship and Super Heavy booster fully qualified, stacked, and sitting at Starbase’s orbital launch site when the FAA finally gives a green light. However, that’s not quite what SpaceX’s reality is today.

SpaceX has made a significant amount of progress in the last month and a half, but contrary to CEO Elon Musk’s hopes as of March 21st, the company will absolutely not be ready to attempt an orbital launch by the end of May. Nonetheless, Shotwell’s estimate of “June or July” may not be completely out of reach. Since Musk’s tweet, SpaceX finished assembling Super Heavy Booster 7, rolled the rocket to the launch site on March 31st, and completed several major tests in early April. However, during the last test, an apparent operator error significantly damaged a large part installed inside the booster, forcing SpaceX to return Super Heavy B7 to Starbase’s build site. After two and a half weeks of repairs, Booster 7 returned to the launch site on May 6th and completed another ‘cryoproof’ test, seemingly verifying that those quick repairs did the job.

Had Booster 7 not required repairs, it’s not impossible (but still hard) to imagine that SpaceX could have had a Super Heavy booster ready to launch by the end of May. Still, the static fire testing Booster 7 needs to complete is almost entirely unprecedented and could take months to complete. To date, SpaceX has never ignited more than six Raptors at once on a Starship prototype, while Super Heavy will likely need to complete multiple 33-engine tests before it can be safely considered ready for flight. Worse, there is no guarantee that SpaceX actually wants to fly Booster 7 after the damage it suffered. If Booster 8 carries the torch forward instead, Starship’s orbital launch debut could easily slip to late Q3 or Q4 2022.

Meanwhile, Super Heavy is only half of the rocket. When Musk tweeted his “hopefully May” estimate, SpaceX was nowhere close to finishing the Starship – Ship 24 – that is believed to have been assigned to the orbital launch debut. However, SpaceX finally accelerated Ship 24 assembly within the last few weeks and ultimately finished stacking the upgraded Starship on May 8th. A great deal of work remains to truly complete Ship 24, but SpaceX should be ready to send it to a test stand within a week or two. Even though the testing Ship 24 will need to complete has been done before by Ship 20, making its path forward less risky than Booster 7’s, Ship 24 will debut a number of major design changes and likely needs at least two months of testing to reach a basic level of flight readiness.

Last but not least, there’s the question of the orbital launch site (OLS) itself. Is the launch mount ready to survive a full Super Heavy static fire? Is the pad’s tank farm ready to fill Starship and Super Heavy with several thousand tons of flammable, explosive cryogenic propellant? If it’s a goal of the test flight, is the launch tower ready for a Super Heavy booster to attempt to land in its arms? While there are reasons to believe that the answer to some of those questions is “yes,” plenty of uncertainty remains and plenty of work is still incomplete.

Ultimately, Shotwell’s June goal is almost certainly unachievable. Late July, however, might be within the realm of possibility, but only in the unlikely event that all Booster 7 and Ship 24 testing is completed almost perfectly and without further delay. For the pragmatic reader, August or September is a safer bet. Thankfully, at least one thing is certain: activity at Starbase is about to get significantly more exciting.

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.
