The follow-on effects of SpaceX’s failed February 15th booster landing have begun to roll in, triggering at least one to two weeks of delays for several upcoming Starlink launches.

Already delayed a few days and leapfrogging an even more beleaguered Starlink-17 launch originally scheduled as far back as late January, SpaceX Falcon 9 booster B1059 lifted off for the sixth time without issue last Monday. The rocket seemed to perform fine, separating as planned around 150 seconds after launch and leaving Falcon 9’s expendable upper stage to continue on its way to orbit with a ~16-ton (~35,000 lb) batch of 60 Starlink satellites.

During B1059’s “reentry burn,” a period where Falcon boosters reignite three of their Merlin 1D engines to both slow down and create a sort of shield with the rocket exhaust that burn produces, something went wrong. Unusual sparks quite literally flew during and after the last few seconds of the burn and the bright flare produced by Falcon 9’s engines dissipated far slower than usual. Eventually, when B1059 was expected to fire up for one final landing burn, all that was visible from a live camera on SpaceX’s drone ship was two flashes of warm light.

It’s hard to say for sure without an official comment from SpaceX but those flashes may have been the drone ship camera capturing the mid-air breakup and fast-fire (or explosion) of the Falcon 9 booster some 20-30 seconds before a planned soft landing. The odd behavior observed during and after the reentry burn could have also indicated a partial loss of thrust in one or more of B1059’s three reentry engines.

Unofficial analysis of the telemetry data included in SpaceX’s public webcasts more or less aligns with that theory, suggesting that Falcon 9 B1059 reentry burn lasted a nominal duration but didn’t slow the rocket down as much as it should have. As a result, B1059 would have been traveling faster and at a lower altitude relative to a nominal Starlink mission, which is exactly what’s observed in a comparison between Starlink-18 and Starlink-19, virtually identical launches completed 11 days apart.

That same telemetry also suggests that Falcon 9 B1059 may have lost thrust before its first burn completed, possibly explaining why the timing of launch events on SpaceX’s webcast and an official SpaceX.com launch timeline began to drastically diverge after MECO. MECO itself occurred about five seconds behind that schedule, gradually ballooning to a difference of more than half a minute for Starlink satellite deployment an hour after launch.

That observation increases the similarity between Starlink-5 and Starlink-19, both of which seemingly suffered a boost phase anomaly, off-nominal reentry burn performance, and booster loss well before landing. SpaceX’s Starlink-5 engine-out anomaly and failed booster landing grounded the company for about five weeks before it eventually returned to flight on April 22nd, 2020.

SpaceX appears to be working to mitigate the impact from Starlink-19 but a delay of at least 1-2 weeks is in order based on current schedules. Perhaps the most chronically delayed SpaceX launch of all time, Starlink-17 – originally scheduled to fly as early as “Jan. 29, Jan. 30, Jan. 31, Feb. 1, Feb. 2, Feb. 4, Feb. 5, Feb. 7, Feb. 17,” and Feb. 25 – is now on the calendar for no earlier than (NET) February 28th. Starlink-20, planned to launch in the last week of February, has been tentatively pushed to no earlier than March 7th. Both dates are assuredly subject – and likely – to change as SpaceX works to close out its Starlink-19 anomaly investigation and implement any necessary changes.

Tesla CEO Elon Musk hits back at drug use claims, calls publications ‘hypocrites’

Elon Musk showed a clean drug test, dispelling any rumors of drug use that came from unfounded reports from two large media outlets.

Tesla CEO Elon Musk has responded to a report from the Wall Street Journal and the New York Times, as both publications claimed he was abusing drugs while being involved with President Trump on both the campaign trail and while he was active within the administration after the election.

A bombshell report from the New York Times, published in late May, stated that Musk was regularly using things like ketamine, ecstasy, and psychedelic mushrooms, and also stimulants like Adderall, during his time within the Trump administration.

The reports cited inside sources who claimed the Tesla and SpaceX frontman was using substances during his time with the government.

However, Musk published the results of a recent drug test performed at Fastest Labs of South Austin. They showed ‘Negative’ results across the board:

Musk was not done there.

He went on to say the New York Times “lies as easy as breathing. It’s normal for them.” He also said both the Times and Wall Street Journal reporters should also publish their own drug test results, stating, “They won’t, because those hypocrites are guilty as sin.”

Musk said years ago that he received ketamine prescriptions from doctors to treat depression. He said he had it “years ago and said so on X, so this is not even news.” He also said that ketamine “helps for getting out of dark mental holes, but haven’t taken it since then.”

Tesla fans and Musk enthusiasts have joked for days now that, if Musk were to be on drugs, other CEOs should also do them, considering his persistence on work-related projects, long hours, and commitment to his job.

Musk has now proven that there has been no drug use with this test, and it seems as if the reports could have some sort of legal impact, although he has not said he will take any action.

Tesla’s Grok integration will be more realistic with this cool feature

Tesla is preparing Grok for its first integration into vehicles, but it’s making it more robust than ever, firmware shows.

Tesla has not yet integrated the AI assistant Grok into its vehicles, but when it does, it will be even more realistic with a new feature that firmware coding shows.

CEO Elon Musk teased a few months back that Grok would be making its way into vehicles in the near future. The implementation has not yet occurred, but we are confident it will be rolling out soon, especially as Tesla has its sights set on a near-term rollout of the Robotaxi platform.

Tesla’s vehicles expected to get Grok voice assistant—but when?

Grok will enable AI assistance for drivers who are both manually operating Tesla vehicles or using the company’s Full Self-Driving suite. It has been widely popular and extremely useful for users on X, Musk’s social media platform.

However, Tesla hacker green has revealed through firmware that the company is planning to roll out Grok into vehicles with personalities, giving it an even more realistic tone that is totally customizable and catered to whatever the driver wants.

There are also a handful of kids’ versions that will do things like tell stories or play trivia:

The true capabilities of Grok are nearly limitless. Back in January, Musk said on a livestream on X that, “You’ll be able to talk to your Tesla and ask for anything.”

Grok appears to only be available on AMD-based vehicles, according to other things green found in the firmware. This means that Intel-based Teslas, which are usually older models, will not enable Grok support for right now.

Tesla dominates Cars.com’s Made in America Index with clean sweep

Tesla continues to dominate Cars.com’s Made in America Index with a clean sweep of the Top 4 spots.

Tesla has dominated the Cars.com Made-in-America Index with a clean sweep of the top four spots. All four Tesla vehicles that were eligible for the analysis placed in the top four.

The Model 3 overtook the Model Y for first place this year. The all-electric crossover was first in 2024, but the Model 3 managed to overtake its sibling vehicle to claim the top spot in 2025. The Model Y took second, while the Model S took third, and the Model X took fourth.

This is an improvement from last year, as the Model Y took first, but the Model S and Model X placed fourth and ninth, respectively. The Model 3 was not in the Top 10 in 2024.

“Tesla continues to lead, claiming the top four spots and showcasing its commitment to domestic production. About 25% of the more than 400 vehicles on sale in the U.S. made this year’s AMI, and whether a vehicle is No. 1 or No.99, it contributes to the U.S. economy,” Patrick Masterson, lead researcher for the program, said.

More than 400 vehicles were analyzed for this year’s study, with Cars.com officially ranking 117 of them. There were two other EVs in the Top 10, as the Kia EV6 took sixth place, and the Volkswagen ID.4 finished in tenth.

This year’s study reflected major geographic and strategic shifts across the automotive industry. Of the 117 vehicles ranked in the program, they were produced at 36 domestic factories, leaving only 11 total factories that did not yield a car on the list. There are 47 assembly plants in operation in the U.S.

However, there still has not been a vehicle to quite reach the 100 percent domestic parts content, something that is extremely elusive. Masterson says the global supply chain is still extremely crucial to even the most American-built cars on the market.

The average domestic parts content of the Top 10 cars was 83.4 percent in 2006, but that number has shrunk to 70.3 percent in this year’s rankings.

Some might wonder where cars like the Tesla Cybertruck or Rivian R1T are on the list. However, these vehicles did not qualify because the study only considers cars under a gross weight of 8,500 pounds.
