SpaceX Falcon 9 doubleheader still on track after fiery ULA launch abort
As previously reported by Teslarati, SpaceX announced intentions to launch two Falcon 9 missions from two Florida launchpads on Sunday, August 30th. However, the ambitious goal was left in limbo.
The record-breaking doubleheader was believed to hinge upon the Saturday morning launch of a United Launch Alliance (ULA) Delta IV Heavy rocket with a classified spy satellite. However, that is apparently no longer the case.
Instead of launching on time, ULA’s infrequently-flown heavy-lift rocket was hit by 72 hours of delays to rectify minor pad hardware bugs. Around 2 am EDT (UTC-4) on August 29th, Delta IV Heavy made it just seconds away from liftoff before the rocket’s autonomous flight computer detected an anomaly with pad hardware and aborted the launch. As a result, the three cores’ three Aerojet Rocketdyne RS-68A engines were forced to shut down after ignition – an uncommon Delta IV launch abort scenario that has historically required at least a week of work to recycle for another launch attempt.
ULA ultimately determined that it was not possible to recycle the countdown for another attempt although enough time remained in the launch window to do so. The launch vehicle was safed and a scrub was announced.
In a statement provided by ULA confirmed that the early shutdown was “due to an unexpected condition during the terminal count at approximately three seconds before liftoff.” ULA also confirmed that “the required recycle time prior to the next launch attempt is seven days minimum.”
ULA has to fly before SpaceX, right?
With a minimum of seven days required to recycle the ULA Delta IV Heavy for another launch attempt, it was unclear what that meant for the fate of the SpaceX SAOCOM-1B mission.
It was previously understood that in order for SpaceX to launch the SAOCOM-1B mission from nearby Space Launch Complex-40 (SLC-40), the ULA Delta IV Heavy would have to successfully launch first. The southern polar launch trajectory of the SAOCOM-1B’s mission is one that hasn’t been flown from Cape Canaveral, FL in nearly six decades. This particular flightpath includes launch hazard zones that inch ever so close to the launchpad of the Delta IV Heavy, which is currently still on its launchpad stacked with a classified payload for the U.S. government.
It was assumed that the Falcon 9 would suffer the same minimum delay of seven days, if not longer. However, on Saturday afternoon, August 29 a SpaceX media representative confirmed that the company was still targeting the historic double header launches on Sunday, August 30.
Double the launches, double the recoveries
If SpaceX can pull it off, Sunday is set to be a stellar day for Falcon 9 launches and landings. The SAOCOM-1B mission will feature a Return To Launch Site (RTLS) landing attempt of the expended Falcon 9 booster while the Starlink Falcon 9 booster is expected to land aboard the autonomous droneship “Of Course I Still Love You” currently stationed off the coast of South Carolina.
In an unusual move, SpaceX split up the fairing catching vessels. Initially, both vessels left Port Canaveral and headed south to a catch zone located between The Bahamas and Cuba in an attempt to catch both fairing halves of the SAOCOM-1B mission. Then, GO Ms.Tree did an about-turn and met up with the booster recovery vessels off the coast of South Carolina.
At the time of publishing, the two Sunday Falcon 9 launches are expected to occur just nine hours apart. The Starlink V1.0-L11 mission is slated to occur at 10:12am ET (1412 UTC) from Launch Complex 39-A at Kennedy Space Center while the SAOCOM-1B mission is set to launch at 7:18pm ET (2318 UTC) from SLC-40 at Cape Canaveral Air Force Station. As usual, SpaceX will host official launch webcasts live, typically beginning around 15 minutes before liftoff.

Elon Musk’s xAI brings 1GW Colossus 2 AI training cluster online
Elon Musk shared his update in a recent post on social media platform X.
xAI has brought its Colossus 2 supercomputer online, making it the first gigawatt-scale AI training cluster in the world, and it’s about to get even bigger in a few months.
Elon Musk shared his update in a recent post on social media platform X.
Colossus 2 goes live
The Colossus 2 supercomputer, together with its predecessor, Colossus 1, are used by xAI to primarily train and refine the company’s Grok large language model. In a post on X, Musk stated that Colossus 2 is already operational, making it the first gigawatt training cluster in the world.
But what’s even more remarkable is that it would be upgraded to 1.5 GW of power in April. Even in its current iteration, however, the Colossus 2 supercomputer already exceeds the peak demand of San Francisco.
Commentary from users of the social media platform highlighted the speed of execution behind the project. Colossus 1 went from site preparation to full operation in 122 days, while Colossus 2 went live by crossing the 1-GW barrier and is targeting a total capacity of roughly 2 GW. This far exceeds the speed of xAI’s primary rivals.
Funding fuels rapid expansion
xAI’s Colossus 2 launch follows xAI’s recently closed, upsized $20 billion Series E funding round, which exceeded its initial $15 billion target. The company said the capital will be used to accelerate infrastructure scaling and AI product development.
The round attracted a broad group of investors, including Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, Qatar Investment Authority, MGX, and Baron Capital Group. Strategic partners NVIDIA and Cisco also continued their support, helping xAI build what it describes as the world’s largest GPU clusters.
xAI said the funding will accelerate its infrastructure buildout, enable rapid deployment of AI products to billions of users, and support research tied to its mission of understanding the universe. The company noted that its Colossus 1 and 2 systems now represent more than one million H100 GPU equivalents, alongside recent releases including the Grok 4 series, Grok Voice, and Grok Imagine. Training is also already underway for its next flagship model, Grok 5.

Tesla AI5 chip nears completion, Elon Musk teases 9-month development cadence
The Tesla CEO shared his recent insights in a post on social media platform X.
Tesla’s next-generation AI5 chip is nearly complete, and work on its successor is already underway, as per a recent update from Elon Musk.
The Tesla CEO shared his recent insights in a post on social media platform X.
Musk details AI chip roadmap
In his post, Elon Musk stated that Tesla’s AI5 chip design is “almost done,” while AI6 has already entered early development. Musk added that Tesla plans to continue iterating rapidly, with AI7, AI8, AI9, and future generations targeting a nine-month design cycle.
He also noted that Tesla’s in-house chips could become the highest-volume AI processors in the world. Musk framed his update as a recruiting message, encouraging engineers to join Tesla’s AI and chip development teams.
Tesla community member Herbert Ong highlighted the strategic importance of the timeline, noting that faster chip cycles enable quicker learning, faster iteration, and a compounding advantage in AI and autonomy that becomes increasingly difficult for competitors to close.
AI5 manufacturing takes shape
Musk’s comments align with earlier reporting on AI5’s production plans. In December, it was reported that Samsung is preparing to manufacture Tesla’s AI5 chip, accelerating hiring for experienced engineers to support U.S. production and address complex foundry challenges.
Samsung is one of two suppliers selected for AI5, alongside TSMC. The companies are expected to produce different versions of the AI5 chip, with TSMC reportedly using a 3nm process and Samsung using a 2nm process.
Musk has previously stated that while different foundries translate chip designs into physical silicon in different ways, the goal is for both versions of the Tesla AI5 chip to operate identically. AI5 will succeed Tesla’s current AI4 hardware, formerly known as Hardware 4, and is expected to support the company’s Full Self-Driving system as well as other AI-driven efforts, including Optimus.

Tesla Model Y and Model 3 named safest vehicles tested by ANCAP in 2025
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025.
The Tesla Model Y recorded the highest overall safety score of any vehicle tested by ANCAP in 2025. The Tesla Model 3 also delivered strong results, reinforcing the automaker’s safety leadership in Australia and New Zealand.
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025. ANCAP’s 2025 tests evaluated vehicles across four key pillars: Adult Occupant Protection, Child Occupant Protection, Vulnerable Road User Protection, and Safety Assist technologies.
The Model Y posted consistently strong results in all four categories, distinguishing itself through a system-based safety approach that combines structural crash protection with advanced driver-assistance features such as autonomous emergency braking, lane support, and driver monitoring.
This marked the second time the Model Y has topped ANCAP’s annual safety rankings. The Model Y’s previous version was also ANCAP’s top performer in 2022.
The Tesla Model 3 also delivered a strong performance in ANCAP’s 2025 tests, contributing to Tesla’s broader safety presence across segments. Similar to the Model Y, the Model 3 also earned impressive scores across the ANCAP’s four pillars. This made the vehicle the top performer in the Medium Car category.
ANCAP Chief Executive Officer Carla Hoorweg stated that the results highlight a growing industry shift toward integrated safety design, with improvements in technologies such as autonomous emergency braking and lane support translating into meaningful real-world protection.
“ANCAP’s testing continues to reinforce a clear message: the safest vehicles are those designed with safety as a system, not a checklist. The top performers this year delivered consistent results across physical crash protection, crash avoidance and vulnerable road user safety, rather than relying on strength in a single area.
“We are also seeing increasing alignment between ANCAP’s test requirements and the safety technologies that genuinely matter on Australian and New Zealand roads. Improvements in autonomous emergency braking, lane support, and driver monitoring systems are translating into more robust protection,” Hoorweg said.
