Just weeks after SpaceX suffered its first in-flight rocket engine failure since 2012, the company has scheduled its next launch on April 16th.

Set to lift off no earlier than (NET) 5:31 pm EDT (21:31 UTC) from NASA Kennedy Space Center (KSC) Launch Complex 39A (Pad 39A), the mission will be SpaceX’s seventh dedicated launch of 60 Starlink satellites. Known as Starlink-6 in reference to the sixth launch of finalized Starlink v1.0 spacecraft, a successful mission could leave SpaceX with some ~410 operational satellites in orbit – significantly more than twice as big as the next largest constellation.

More importantly, Starlink-6 will mark a sort of return-to-flight for Falcon 9 after booster B1048 suffered an in-flight engine failure and missed its landing attempt on March 18th. While the booster was able to sacrifice itself to ensure that the overall Starlink-5 mission was a success, any in-flight failure is still a significant event in aerospace. To that end, very little is known about the Starlink-5 anomaly, aside from announcements that both NASA and the US Air Force will be paying close attention to the results of SpaceX’s internal investigation. Starlink-6’s imminent launch is now the latest piece of that puzzle, shedding some welcome light on the situation.

Unsurprisingly, an in-flight Falcon 9 engine failure more than piqued the curiosities of high-profile SpaceX customers like NASA and the US Air Force (and Space Force), both of which have some of the company’s most important launches ever scheduled within the next few months. Most notably, NASA noted on March 25th that the space agency and SpaceX “are holding the current mid-to-late May [target for Crew Dragon’s inaugural astronaut launch] and [will] adjust the date based on review of the [engine failure] data, if appropriate.”

At time of comment, a few aspects of the unfortunate Starlink-5 engine failure were already positioned in SpaceX’s favor. Critically, it was the first time that a flight-proven Falcon 9 booster launched on its fifth orbital-class mission, meaning that the very same booster – B1048 – had already launched four times prior. In aerospace parlance, the mission thus served as a pathfinder for SpaceX’s reusable rocketry technology, venturing into new territory. Since it began internal Starlink launches, SpaceX has used those opportunities to take its most recent reusability leaps without risking customer payloads in the process.

At least for now, neither NASA or the USAF have plans to fly their most valuable payloads on flight-proven Falcon boosters. While that may change over the next several years, it means that SpaceX’s Starlink-5 anomaly and missions like Crew Dragon Demo-2 and GPS III SV03 – both set to fly on new boosters – share much less commonality. Of course, this assumes that B1048’s March 18th engine failure is directly related to the booster’s exceptionally flight-proven nature. Were SpaceX’s investigation to conclude that the fault had nothing to do with multi-launch wear and tear, it would likely ground Falcon 9 and Falcon Heavy indefinitely.

Despite a relatively hard landing after its third launch, Falcon 9 booster B1051 is scheduled to fly its fourth mission – Starlink-6 – just 79 days later. (Richard Angle)

Instead, SpaceX – knowing full-well the potential consequences of two consecutive in-flight failures – has decided to attempt another orbital-class Starlink launch and booster landing less than a month after Starlink-5. To be clear, while SpaceX could choose to throw caution to the wind on an internal launch, it’s doubtful that it would haphazardly take such a substantial risk. Instead, Starlink-6’s April 16th launch date strongly suggests that SpaceX is already reasonably confident that it’s both determined the likely culprit of last month’s engine failure and identified ways to prevent its reoccurrence.

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.
