SpaceX Starlink launch suffers third weather scrub, next attempt Tuesday
Update: Multiple weather constraint violations forced SpaceX to scrub today’s Starlink-12 launch attempt less than half an hour before liftoff, marking the mission’s third weather-related scrub and fourth abort overall since mid-September. As of October 4th, the US Air Force 45th Space Wing predicted a 40% chance of weather violation.
SpaceX’s fifth Starlink-12 launch attempt is scheduled no earlier than 7:29 am EDT (11:29 UTC) on Tuesday, October 6th. The mission-specific T-1 weather forecast predicts a 70% chance of favorable conditions.
On the heels of a rare last-second Falcon 9 launch abort, SpaceX is closing in on its third attempt to launch the 12th batch of operational Starlink satellites.
Scheduled to lift off from Kennedy Space Center (KSC) Launch Complex 39A (Pad 39A) no earlier than (NET) 7:51 am EDT (11:51 UTC) on Monday, October 5th, Starlink-12 was originally scheduled to launch in mid-September. Bad weather at the Atlantic Ocean landing zone caused a ten-day delay from September 17th to the 27th, followed by a pad weather delay on the 28th.
After a ULA Delta IV Heavy mission with range priority was scrubbed for the seventh time on September 30th, SpaceX tried to launch Starlink-12 again but suffered an abort – later blamed on a pad sensor – seven seconds before liftoff. Finally, a new Falcon 9 launch with an upgraded GPS III satellite aboard was aborted just two seconds before liftoff on October 2nd. Moved from NET October 3rd to the 5th just prior to GPS III SV04’s separate launch delay, Starlink-12 is now up next.
Interrupting what has otherwise been a much-improved level of launch readiness and schedule reliability for Falcon 9 and Falcon Heavy’s Block 5 upgrade, this recent string of delays – while mostly the result of weather and ULA’s own NROL-44 launch delays – has even become a concern for CEO Elon Musk. Currently focused on building out SpaceX’s new Starship factory and pushing towards the rocket’s first high-altitude and orbital test flights in Boca Chica, Texas, Musk stated that he would be flying to Cape Canaveral “to review hardware in person” on the week of October 5th.
Musk also says that SpaceX is “doing a broad review of launch site, propulsion, structures, avionics, range, & regulatory constraints” to determine if an apparent goal of “48 launches” in 2021 is feasible.
To be fair to SpaceX, most of the plague of delays suffered by the company in the last month has been caused by a mixture of weather and the range’s preferential treatment of ULA’s “national security” NROL-44 launch. Additionally, of an impressive seven ULA NROL-44 launch attempts between August 26th and September 30th, just a single one was caused by weather – the remaining six a result of a wide variety of technical software and hardware bugs. SpaceX’s Starlink-12 and GPS III SV04 missions have only suffered one technical launch abort each on September 30th and October 2nd.
In other words, short of upgrading Falcon rockets to launch and land in worse weather conditions, most of SpaceX’s delays have been largely out of the company’s control, while ULA’s NROL-44 struggles demonstrate just how much worse things could be. According to an unofficial analysis of 44 Falcon Block 5 launches since May 2018, only four technical launch aborts have been triggered by a booster fault. Pad-caused aborts have been roughly as common, meaning that 1 in roughly 6 to 8 SpaceX launches suffers some kind of abort shortly before liftoff, on average.
Altogether, Falcon Block 5 rockets have been relatively dependable for on-time, on-schedule launches even if SpaceX has struggled with more repeated delays than usual in the last few months. To achieve anywhere close to 48 launches annually, however, major improvements will need to be made, likely including upgrades to whatever is responsible for Falcon 9’s weather constraints. As of October 2020, SpaceX has never launched four times in one month (or four times in the same ~30-day period). To launch 48 times in one year, SpaceX will need to average four launches per month. That, of course, in no way accounts for the possibility that 2020-esque summer weather could functionally cut 4-8+ weeks off of Falcon 9’s annual availability.
Regardless, SpaceX will begin live coverage of the third Starlink-12 launch attempt around 7:35 am EDT (11:35 UTC). Tune in to (hopefully) catch the company’s 17th launch this year.

SpaceX has updated its target for the thirteenth integrated flight test of Starship, aiming for as early as Thursday, July 23. The 90-minute launch window opens at 5:45 p.m. CT from the company’s Starbase facility in South Texas.
The target flight was initially rescheduled for today, but SpaceX pushed it back again.
This latest adjustment follows an aborted attempt earlier in the week and reflects the iterative, rapid-development approach that has defined the Starship program. With the vehicle already stacked and ground teams making final preparations, the mission represents another step toward proving the full reusability of the world’s most powerful rocket system.

The original launch attempt on July 16 was scrubbed at T-0 when several Raptor engines on the Super Heavy booster failed to ignite properly. The automatic abort system triggered just as the engines began their startup sequence, preventing liftoff.
SpaceX CEO Elon Musk confirmed that some engines did not start as expected, prompting the decision to replace two Raptors on Booster 20 to ensure reliability. The issue occurred despite a successful full-duration static fire earlier, highlighting the complexities of coordinating 33 engines under flight conditions.
This cautious approach underscores SpaceX’s commitment to safety amid an aggressive test cadence.
Flight 13 builds directly on the lessons from Flight 12 in May 2026. The Super Heavy booster’s primary goals include a successful liftoff, ascent, stage separation, boostback burn, and controlled splashdown in the Gulf of America.
Hardware and software modifications address the off-nominal flip and boostback burn problems from the prior flight, where propellant slosh and engine relight issues led to an uncontrolled impact.
For the Starship upper stage, objectives include deploying 20 operational Starlink V3 satellites, the first real payload of this type, performing a single Raptor engine relight in space, and executing a controlled entry, descent, and splashdown in the Indian Ocean. Propulsion upgrades aim to improve engine-out capability after one vacuum Raptor was lost on Flight 12.
Additional test elements focus on heat shield performance. Six satellites carry cameras to image the tiles during flight, while white-painted tiles and upgraded attachments on flaps and the aft skirt will gather data for future reusability.
The FAA completed its mishap investigation into Flight 12 earlier this month, clearing the regulatory path.
This suborbital mission, the second with V3 vehicles, advances Starship toward operational missions, including potential crewed flights and support for NASA’s Artemis program. Success would mark significant progress in rapid reusability and satellite deployment from the massive system.
Elon Musk dismissed reports claiming SpaceX had placed a massive order for NVIDIA GPUs worth $52 billion. The denial came hours after Taiwanese media, citing unnamed industry sources, reported that SpaceX planned to acquire approximately 13,000 AI server racks, equating to roughly 1 million GB300 GPUs, from Foxconn.
Each rack was estimated at around $4 million, with deliveries potentially starting in late 2025.
The story suggested this would mark SpaceX’s first major foray into Foxconn-manufactured NVIDIA hardware, breaking from suppliers like Supermicro and Dell. Musk responded bluntly on X:
This is fake news
— Elon Musk (@elonmusk) July 20, 2026
Despite the denial, the rumored scale aligns with SpaceX’s explosive growth in AI infrastructure. NVIDIA’s GB300 (successor to the GB200 NVL) racks deliver unprecedented performance for large-scale training and inference. A $52 billion commitment would dwarf most corporate AI budgets and provide the compute muscle needed for frontier models.
SpaceX already operates gigawatt-scale terrestrial clusters like Colossus in Memphis, Tennessee, and has monetized them aggressively through leasing deals.
SpaceX’s newest Starmind will make earth data centers obsolete
Major customers include Anthropic (paying ~$1.25 billion monthly for 220,000+ GPUs), Google (~$920 million monthly for 110,000 GPUs), and Reflection AI. These arrangements are projected to generate tens of billions in annual revenue, far outpacing traditional SpaceX businesses.
Such an investment would fuel internal AI efforts, particularly Grok models under the integrated SpaceXAI division, while supporting ambitious orbital data center plans. SpaceX envisions launching thousands of AI-optimized satellites powered by solar energy and cooled in space, bypassing terrestrial power and land constraints.
This “Starmind” constellation could position the company as a leader in space-based computing.
SpaceX as an Emerging AI Powerhouse
Once primarily known for reusable rockets and Starlink satellite internet, SpaceX has transformed into a multifaceted AI player.
The 2026 acquisition of xAI integrated Grok development directly into the company. Starlink’s low-latency global network complements massive compute clusters, enabling efficient data flow for training and serving AI models.
Musk has long argued that AI scaling demands solutions beyond Earth, citing things like real estate and electricity limits on the ground.
While the Foxconn deal may not be in the cards, SpaceX’s trajectory is continuing on the path of blending aerospace engineering with hyperscale AI to dominate both launches and intelligence infrastructure.
Elon Musk shed more details on the upcoming improvements to Tesla’s Full Self-Driving suite, specifically one that the CEO mentioned last week, which should help owners see fewer interventions.
Last week, Musk hinted that one major improvement that Tesla planned to roll out to Full Self-Driving users was the car’s ability “to remember your specific interventions and match each person’s individual preferences.”
Elon Musk says your Tesla will start to learn your individual preferences
This small bit of detail was linked to a post from Tesla community member Whole Mars, who said that FSD’s tendency to exit the carpool lane, a feature that owners can turn on but at times the car will disregard.
It sounds like, based on Musk’s two responses since that original post, it is safe to say the things FSD will start to remember are wide-ranging. However, it seems the biggest differences will be noticed with parking performance, which Musk continues to mention.
Highway Lane Preferences
The initial post Musk mentioned, with these new remembered preferences soon to arrive for Tesla owners everywhere, was the Carpool/Express Lane.
Tesla has a setting in the FSD menu that lets drivers enable HOV Lane travel. However, the car won’t always stay in that suggested or preferred lane.
The car will start to remember your specific interventions and match each person’s individual preferences
— Elon Musk (@elonmusk) July 18, 2026
Some owners have also complained of left lane camping, an illegal maneuver in at least some states. Cruising in the passing lane has resulted in tickets for some, as it is illegal in over 30 states in the U.S.
Tesla did not confirm if these preferences would also be included in new FSD behaviors, but it would certainly help move the company toward fewer interventions.
Parking Preferences
This seems to be the real focus of the entire operation, as Musk stated several weeks ago that parking was overwhelmingly the most frequent reason for interventions.
The major issue with parking is not necessarily the parking “performance,” as FSD is generally good at parking. It definitely has its issues; we’ve recorded plenty of them, including this one as recent as last week:
Yeah it seems like FSD v14.3.5 is having some issues with parking early on https://t.co/Bw5ULfVmDq pic.twitter.com/RHdpjOEpIo
— TESLARATI (@Teslarati) July 13, 2026
However, the changes coming are more about preferences, meaning where you park and how your car enters the spot, either pulling in or backing in. Owners have also reported that pulling into the correct driveway is a relatively rare thing for FSD, something else that needs to be confronted.
Musk basically confirmed that all of these things would be part of Tesla’s plan to address driver preferences with FSD:
Yes
— Elon Musk (@elonmusk) July 20, 2026
It’s obvious there is something big coming with FSD, and the company’s focus seems to be eliminating any intervention that would be related to preferences. This is probably the biggest bottleneck between Tesla and being fully autonomous. Critical interventions do occur, but they are much less frequent.
The only time a driver should be taking over is because of a critical intervention; this seems to be the goal of Tesla right now.
This all seems to be a priority as Tesla continues to move closer to the prospect of unsupervised driving.
