SpaceX CEO Elon Musk updates schedule for first orbital Starship launch

Published

on

SpaceX CEO Elon Musk has presented the first significant update on the company’s Starship program since September 2019, offering a couple of new details about the status of the first orbital launch attempt of the largest and most powerful rocket ever built.

Unfortunately, above all else, the promised update was primarily a rehash of the broad-strokes vision of SpaceX’s Starship and Mars programs, as well as some basic details – most already known – about the rocket, its Raptor engines, and how it will be operated. Nonetheless, a large portion of the event was dedicated to audience questions, some of which actually extracted some specific details from the SpaceX CEO. Perhaps the single most important news: a rough but updated schedule for Starship’s first orbital test flight.

To be clear, a great many questions remain unanswered. Months after Starbase’s first orbital tank farm reached some degree of completion, SpaceX has yet to fill four main liquid methane (LCH4) tanks with even an ounce of fuel. Over the same period, the farm’s five liquid oxygen and nitrogen (LOx/LN2) tanks have been filled with thousands of tons of propellant and coolant. Why is still entirely unclear, save for speculation that SpaceX ran afoul of rudimentary methane storage regulations and is ever so slowly rectifying those errors with modifications. Without so much as a partially operational tank farm, SpaceX will be unable to attempt an orbital Starship launch, let alone start the process of qualifying a Super Heavy booster for flight with wet dress rehearsals (WDRs) and static fire tests.

Musk also failed to confirm or offer an educated guess as to which Starship and Super Heavy booster will support the first orbital test flight (OTF), whether the first OTF will truly reach orbit (rather than ‘just’ orbital velocity), and what will happen to Ship 20 and Booster 4 if – as a great deal of speculation suggests – they’ve fallen out of favor. If they’re to be replaced, it’s also unclear why that is or how long it might take to qualify a new ship and booster given that Super Heavy B4, for example, has yet to attempt a single static fire test a full six months after it first reached its full height.

Nonetheless, largely thanks to questions asked by members of the media, Musk did offer some valuable insight into Starship’s first orbital-class test flight. The SpaceX CEO says that he believes the Federal Aviation Administration (FAA) could complete an environmental assessment of Starbase as early as March. In the same presentation, Musk stated that SpaceX would “hopefully [complete environmental reviews] a couple months.” A lack of environmental approval has been the single most important bottleneck of orbital Starbase launch operations for months. The FAA originally anticipated that those reviews would be complete by the end of 2021 but recently delayed the estimated date of completion to the end of February 2022. Another delay from February to March (or later) has been expected for weeks.

It’s unclear how seamless the whole process will be but SpaceX will also need to receive an FAA license for orbital Starship launches after clearing environmental reviews. That could take days, weeks, months, or even a year or more. If SpaceX doesn’t receive a Finding Of No Significant Impact (FONSI) on its Starbase environmental assessment (EA) and instead has to complete a far more extensive Environmental Impact Statement (EIS), Starbase could be stuck in bureaucratic gridlock well into 2023 or even 2024.

Thankfully, Musk is extremely confident in SpaceX’s alternatives. In the event that Starbase becomes indefinitely unusable, SpaceX has already received full environmental approval to launch Starship out of Kennedy Space Center Pad 39A. The company has already begun the process of assembling a Starship launch and catch tower offsite and Musk believes that a Pad 39A Starship launch site could be brought online in just 6-8 months if SpaceX refocuses all of its Starship resources onto Florida.

The CEO also says that SpaceX’s goal is to have the hardware needed for Starship’s first orbital test flight ready to launch around the same as regulatory approval is secured – “hopefully a couple months for both,” in Musk’s words. If Starship S20 and Booster 4 are still assigned to mission, that schedule is not difficult to believe. Starship has already completed virtually all of the ground testing needed to qualify it for flight, while – from the outside – Super Heavy has never looked more ready for static fire testing.

If SpaceX intends to use a different ship and booster, though, the company will have to cut the amount of time needed for final assembly and qualification testing by a factor of two or three relative to B4/S20. If the next ship and booster pair takes a similar amount of time as B4/S20, the hardware needed for Starship’s first orbital launch attempt might not be ready until August or September 2022. SpaceX will also need to build, test, qualify, and ship around three-dozen Raptor 2 engines, the production of which could singlehandedly take at least six or seven weeks at the current pace of production.

Ultimately, no matter where the cards currently in the air end up falling, it looks like SpaceX has an extremely busy – and hopefully fruitful – year of Starship development and testing ahead of it

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.
