SpaceX rocket ready for second reusability record, Starlink launch attempt
One of SpaceX’s first upgraded Falcon 9 Block 5 boosters is ready for its second attempt to set a reusability record after its March 15th Starlink launch attempt aborted at the very last second.
Now scheduled to send SpaceX’s sixth batch of 60 Starlink satellites into orbit no earlier than (NET) 8:16 am EDT (12:16 UTC), March 18th, the mission will be Falcon 9 booster B1048’s fifth. Just four months ago, the booster successfully launched the first 60 upgraded Starlink v1.0 satellites, also becoming the second SpaceX rocket to fly four times. While B1049 – B1048’s predecessor – was first to reach the four-flight milestone in May 2019, B1048 is now on track to take the next leap forward for Falcon 9 reusability.
First noted shortly after the abort on SpaceX’s March 15th launch webcast, the company later clarified that what could have been attributed to hardware failure was likely just an issue with software or sensors. Milliseconds before liftoff, Falcon 9’s autonomous flight computer seemingly didn’t like what it saw while interpreting the telemetry flowing in from the ignition of B1048’s nine Merlin 1D engines. Whatever the specific trouble, Falcon 9 believed that one or several of those Merlin 1D engines were producing more thrust than they should.
While likely oversimplifying what is a spectacularly complex logic system, the flight computers that control Falcon launch vehicles from T-1 minute to mission completion have to treat the messy uncertainty of reality through a black and white lens. Lacking the ability to heuristically interpret the data they process, the computers instead rely on algorithms that filter thousands of channels of telemetry into a handful of simple categories. If that data aligns with the computer’s expectations, things are okay. If the data doesn’t agree with the plan, things are not okay. There are, of course, many more levels of complexity, but the concept of operations remains mostly the same.
However, the telemetry itself is also a potential point of failure – bad data could lead the flight computer astray, concluding that things are okay when they aren’t or vice versa. To handle that potential failure mode, SpaceX relies on multiple strings of telemetry (and even multiple computers), all gathering and analyzing the same things simultaneously. If one of several redundant sensors starts to disagree with its brethren, reporting different data back to Falcon 9’s flight computers, it’s apparent that the sensor – not the thing it’s measuring – is likely at fault. Still, out of an abundance of caution, SpaceX avionics typically treat most “out-of-family” sensor readings as reason enough to delay or fully abort a launch. When a launch delay can be little more than an annoyance with a negligible cost, it’s almost universally better to be safe than sorry.
With Falcon 9 B1048’s March 15th false start, the rocket’s computer appears to have received conflicting readings from the same family (or families) of engine thrust sensors. While, as noted above, the fault almost certainly lay in an engine sensor or two and not in the engines themselves, the flight computer chose caution over expedience and halted the launch milliseconds before it would have otherwise commanded clamp release and lifted off.
Confirmed by SpaceX delaying the Starlink V1 L5 mission by just three days, the issue was almost certainly software or sensor-related. Given that SpaceX continues to push the envelope of launch vehicle reusability, it’s honestly more surprising that aborts like these aren’t more common. Instead, the reality is that Falcon 9 Block 5 – aside from delays from the occasional upper stage fault – almost never suffers hardware-related aborts when compared to the rocket’s prior iterations.
Featuring the second-ever flight-proven Falcon payload fairing, Falcon 9 B1048 will hopefully become the first SpaceX rocket to complete five orbital-class launches and landings. With more than a little luck, there’s also a smaller chance that the mission could mark the first time SpaceX successfully catches both fairing halves with twin ships Ms. Tree and Ms. Chief.
Tune in for SpaceX’s second Starlink V1 L5 launch attempt around 8am EDT (12:00 UTC) to catch the potentially record-breaking launch and landing live.

NHTSA just escalated its Tesla Cybercab investigation in a big way
NHTSA escalated its Cybercab audit into a sworn Special Order with a September 30 deadline.
Federal regulators have moved from asking Tesla questions about its Cybercab to demanding sworn answers. The National Highway Traffic Safety Administration issued a Special Order that requires a Tesla officer to sign an affidavit attesting to the completeness of the company’s responses, with a deadline of September 30.
The order builds on Audit Query AQ26002, which NHTSA opened on September 3, the same day Tesla began commercial Cybercab service in Austin. Teslarati covered that initial inquiry when it surfaced, noting the agency wanted to understand how Tesla certified a vehicle with no permanently attached steering wheel, pedals, or mirrors as compliant with Federal Motor Vehicle Safety Standards. A Special Order is a different tool and converts a fact finding review into a legally enforceable demand, the same mechanism NHTSA used against Tesla in 2023 during its Autopilot investigation.
Several of the 21 requests target a specific gap in Cybercab’s design. One asks whether Tesla used temporarily attached human controls at any point to help certify the vehicle, and if so, which standards depended on that equipment being present. Another quotes an existing rule directly: “The service brakes shall be activated by means of a foot control.” Cybercab has no foot pedal. NHTSA wants a detailed explanation of how the vehicle satisfies that requirement, and how it complies without the kind of exemption granted to Zoox in July under Part 555, the regulatory pathway built for steering wheel free vehicles.
The order does not claim Cybercab is unsafe or that Tesla broke a rule. It requires Tesla to explain, under oath, the reasoning behind decisions the company already made when it self-certified the vehicle. That distinction matters, but so does the exposure. Motor1’s reporting, summarized here, put potential civil penalty exposure as high as $139 million if NHTSA later finds the certification was flawed, on top of whatever criminal risk comes with a false sworn statement.
Tesla has not said publicly how it plans to respond. Cybercab is still carrying passengers in Austin through the Robotaxi app while the September 30 deadline approaches, and the company has continued expanding the vehicle’s footprint even as the regulatory question remains open. The Special Order does not pause any of that and just sets a date by which Tesla has to put its certification logic on the record, with a company officer’s name attached to it.
In a new interview on Wednesday, Tesla uber bull Ron Baron said that anyone looking to buy the company’s stock should do so as soon as they can.
Baron, founder and CEO of Baron Capital and one of Tesla’s most persistent institutional bulls, used a CNBC Squawk Box appearance on Wednesday to deliver a familiar message with fresh urgency: In his opinion, Tesla stock is a buy:
“The time to buy the stock is now. FSD is catching on, and it’s going to be bigger and bigger. 55% of new buyers are buying it (Teslas) with FSD. It’s going to be everywhere. It’s safer.”
The Baron Capital frontman’s case is built around Full Self-Driving. Tesla reported 1.48 million active FSD subscriptions in the second quarter, up 56 percent year over year, and company officials have said roughly 55 percent of new North American deliveries left with a subscription enabled.
Baron framed that attach rate as proof the product is moving from enthusiast extra to default expectation, and as a reason software, not just vehicle volume, should drive the next phase of value.
His conviction on Tesla shares is not theoretical, as Baron Capital made its first Tesla investment in 2014, after years of meetings that began around the 2010 IPO roadshow. The firm later built a large SpaceX position starting in 2017.

Baron said those Musk-led bets have generated about $30 billion of the $71 billion in profits Baron Capital has produced for clients. He put the firm’s current exposure at roughly $25 billion in SpaceX and $5 billion in Tesla. Personally, he described SpaceX as his largest holding, at about $5 billion, with about $1.5 billion in Tesla and additional Tesla exposure through the firm’s funds.
That concentration is also a statement of loyalty. Asked about talk of a SpaceX-Tesla combination, Baron said he had already walked Elon Musk through arguments for and against a deal, then declined to repeat them on air. His public position was simpler: “Whatever you decide is better is what I’m going to support,” he said to Musk.
Baron also said that he picked up the farewell edition of the Model S after Tesla decided to sunset the vehicle earlier this year, calling it his favorite car he’s ever driven.

SpaceX’s next Starship launch is about to attempt its biggest leap yet
SpaceX targets September 22 for Starship Flight 14, its first attempt to reach real orbit.
SpaceX has set September 22 as the target date for Starship’s 14th test flight, and this one carries a different goal than any of the 13 that came before it. Every previous Starship mission has intentionally flown a suborbital arc, reentering the atmosphere within the same hour it launched. Flight 14 is designed to send the craft into a genuine orbit around Earth for the first time.
The launch window opens at 7:15 a.m. Central time at Starbase in South Texas and runs for 75 minutes, pending regulatory approval, according to SpaceX’s mission description published Tuesday. If the flight goes as planned, Starship will circle the planet roughly six times at an altitude near 275 kilometers over about ten hours before a deorbit burn sends it toward a splashdown in the Pacific Ocean west of Chile, a departure from the Indian Ocean recoveries used on the last several flights.
The mission also marks the first attempt to put a working batch of Starlink V3 satellites into actual service. Flight 13 carried 20 of the new satellites in July, but because that mission never left a suborbital trajectory, the payload reentered along with the ship instead of separating into orbit.
SpaceX tells the FCC that Starship Flight 14 is going to orbit
Each V3 satellite is rated for roughly one terabit per second of downlink capacity, so a successful deployment on Flight 14 would be SpaceX’s largest single jump in network bandwidth since Starlink began flying on Falcon 9.
Flight 13 still did the heavier lifting on the technical side. That July mission flew a deliberately more stressful reentry profile to test Starship’s heat shield, and the ship survived its softest splashdown yet, intact enough for drone inspections shortly after landing. Elon Musk said the flight delivered “all the heat shield data we needed and then some,” a result Teslarati covered in detail when he later said SpaceX had solved the vehicle’s biggest reusability challenge. Flight 14 is where SpaceX starts spending that confidence on an actual orbital insertion rather than another controlled fall back to Earth.
One thing Flight 14 will not attempt is a tower catch of the ship. Musk floated the idea right after Flight 13, but walked the timeline back in August, saying a catch attempt was more likely “in a few months.” The Super Heavy booster will still aim for its own recovery, targeting an offshore landing point in the Gulf of America, the same approach used on recent flights.
September 22 is SpaceX’s own target, not a locked date. Starship’s schedule has slipped before over hardware readiness and FAA sign off, and the company has said as much in its own mission notes. But the plan itself represents the clearest marker yet that Starship is moving from a suborbital test program into something meant to carry paying payloads and, eventually, people.
