SpaceX CEO Elon Musk explains why Falcon Heavy’s center core missed the drone ship
Some 12 hours after Falcon Heavy successfully completed what Elon Musk described as the SpaceX’s “most difficult launch ever”, the CEO took to Twitter to offer some insight into the mission’s only sad note – an unsuccessful center core recovery attempt.
The second Falcon Heavy Block 5 center core built by SpaceX, B1057 suffered an untimely demise shortly after its first (and last) launch, failing to successfully land aboard drone ship Of Course I Still Love You (OCISLY). Although an undeniable disappointment, the overall STP-2 mission was a spectacular success and will without a doubt serve SpaceX well as the company eyes its first certified Falcon Heavy launches for the US military. New center cores can and will be produced and there should be no doubt that SpaceX will eventually perfect center core recovery (or transcend the need entirely with Starship).
As noted by both CEO Elon Musk and several SpaceX engineers-turned-webcast-hosts, aside from the fact that the overall mission was by far the company’s most challenging yet, center core B1057’s recovery was also expected to be the most challenging booster landing ever. The booster’s landing target was drone ship OCISLY, stationed a record-smashing 1240 km (770 mi) off the coast of Florida – almost 30% further than any previous recovery attempt.
Sadly, SpaceX either chose not to broadcast the center core’s onboard camera during reentry or the booster could not maintain a downlink connection during the ordeal. However, based on basic info that was included in the webcast, B1057 completed its boost burn and separated from the upper stage and Space Test Program-2 (STP-2) payload some 3 minutes and 40 seconds after lifting off from Pad 39A. At MECO (main-engine cutoff), the building-sized booster was traveling a blistering 3.1 km/s (Mach 9) at an altitude of more than 120 km (75 mi).
Running on slim propellant margins, the booster coasted through vacuum almost the entire way to drone ship OCISLY. Around 9 minutes after launch, B1057 began its entry burn, likely igniting three Merlin 1D engines to effectively cushion it against the worst of atmospheric reentry heating. Unintuitively, much of the actual benefit of that burn derives from that cushioning effect, while the burn only slows the booster down by a few hundred meters per second (mph).
Effectively falling in near-vacuum conditions, pulled by gravity, B1057 could easily have been traveling 3.5-4 km/s (Mach 10-12) by the time Earth’s atmosphere began to slow it down. Described by Musk himself, back-of-the-envelope analysis of available telemetry apparently indicated that that spectacularly fast and hot reentry either burned through B1057’s heavy titanium heat shield or broke through the smaller heat shield surrounding its M1D engine bells.
In short, the brutal heating and buffeting of hypersonic atmospheric reentry damaged the rocket’s central M1D engine, necessary for an accurately controlled drone ship landing. Incredibly, B1057 actually appeared to make it almost all the way to a successful recovery, veering off course just a few hundred meters above OCISLY. Musk also noted that this may have actually been an instance of the rocket’s autonomous guidance computer intentionally abort a landing attempt to protect the drone ship. It’s possible that the reentry didn’t fully destroy components, but rather damaged them to the point that they failed only after a sustained landing burn.
Regardless, the end result is unambiguous. Falcon Heavy center core B1057 did its job perfectly, supporting the STP-2 launch, boosting the upper stage and payload almost half the way to orbit, and eventually sacrificing itself to avoid potentially damaging OCISLY. SpaceX’s next Falcon Heavy launch is currently scheduled to launch the very large AFSPC-52 military satellite no earlier than September 2020, a full 15 months away. The company should have no trouble manufacturing multiple new center cores between now and then.

Tesla called ‘biggest meme stock we’ve ever seen’ by Yale associate dean

Tesla (NASDAQ: TSLA) is being called “the biggest meme stock we’ve ever seen” by Yale School of Management Senior Associate Dean Jeff Sonnenfeld, who made the comments in a recent interview with CNBC.
Sonnenfeld’s comments echo those of many of the company’s skeptics, who argue that its price-to-earnings ratio is far too high when compared to other companies also in the tech industry. Tesla is often compared to companies like Apple, Nvidia, and Microsoft when these types of discussions come up.
Fundamentally, yes, Tesla does trade at a P/E level that is significantly above that of any comparable company.
However, it is worth mentioning that Tesla is not traded like a typical company, either.
Here’s what Sonnenfeld said regarding Tesla:
“This is the biggest meme stock we’ve ever seen. Even at its peak, Amazon was nowhere near this level. The PE on this, well above 200, is just crazy. When you’ve got stocks like Nvidia, the price-earnings ratio is around 25 or 30, and Apple is maybe 35 or 36, Microsoft around the same. I mean, this is way out of line to be at a 220 PE. It’s crazy, and they’ve, I think, put a little too much emphasis on the magic wand of Musk.”
Many analysts have admitted in the past that they believe Tesla is an untraditional stock in the sense that many analysts trade it based on narrative and not fundamentals. Ryan Brinkman of J.P. Morgan once said:
“Tesla shares continue to strike us as having become completely divorced from the fundamentals.”
Dan Nathan, another notorious skeptic of Tesla shares, recently turned bullish on the stock because of “technicals and sentiment.” He said just last week:
“I think from a trading perspective, it looks very interesting.”
Nathan said Tesla shares show signs of strength moving forward, including holding its 200-day moving average and holding against current resistance levels.
Sonnenfeld’s synopsis of Tesla shares points out that there might be “a little too much emphasis on the magic wand of Musk.”
Elon Musk just bought $1 billion in Tesla stock, his biggest purchase ever
This could refer to different things: perhaps his recent $1 billion stock buy, which sent the stock skyrocketing, or the fact that many Tesla investors are fans and owners who do not buy and sell on numbers, but rather on news that Musk might report himself.
Tesla is trading around $423.76 at the time of publication, as of 3:25 p.m. on the East Coast.

Tesla makes big change to Full Self-Driving doghouse that drivers will like
Now, it is changing the timeframe of which strikes will be removed, cutting it in half. The strikes will be removed every 3.5 days, as long as no strikes are received during the time period.

Tesla is making a big change to its Full Self-Driving doghouse that drivers will like.
The doghouse is a hypothetical term used to describe the penalty period that Tesla applies to drivers who receive too many infractions related to distracted driving.
Previously, Tesla implemented a seven-day ban on the use of Full Self-Driving for those who received five strikes in a vehicle equipped with a cabin camera and three strikes for those without a cabin camera.
It also forgave one strike per week of Full Self-Driving use, provided the driver did not receive any additional strikes during the seven-day period.
Now, it is changing the timeframe of which strikes will be removed, cutting it in half. The strikes will be removed every 3.5 days, as long as no strikes are received during the time period.
The change was found by Not a Tesla App, which noticed the adjustment in the Owner’s Manual for the 2025.32 Software Update.
The system undoubtedly helps improve safety as it helps keep drivers honest. However, there are definitely workarounds, which people are using and promoting for monetary gain, and you can find them on basically any online marketplace, including TikTok shop and Amazon:
🚨 Seeing more and more devices like this land on various online marketplaces including TikTok shop and Amazon
These devices are NOT to be used when operating Tesla Full Self-Driving and I’d love to see Tesla take action here.
These “creators” looking to make a quick buck are… pic.twitter.com/VnY25k2mPL

People are marketing the product as an FSD cheat device, which the cabin-facing camera will not be able to detect, allowing you to watch something on a phone or look through the windshield at the road.
The safeguards implemented by Tesla are designed to protect drivers from distractions and also protect the company itself from liability. People are still using Full Self-Driving as if it were a fully autonomous product, and it is not.
Tesla even says that the driver must pay attention and be ready to take over in any scenario:
“Yes. Autopilot is a driver assistance system that is intended to be used only with a fully attentive driver. It does not turn a Tesla into a fully autonomous vehicle.
Before enabling Autopilot, you must agree to “keep your hands on the steering wheel at all times” and to always “maintain control and responsibility for your vehicle.” Once engaged, Autopilot will also deliver an escalating series of visual and audio warnings, reminding you to place your hands on the wheel if insufficient torque is applied or your vehicle otherwise detects you may not be attentive enough to the road ahead. If you repeatedly ignore these warnings, you will be locked out from using Autopilot during that trip.
You can override any of Autopilot’s features at any time by steering or applying the accelerator at any time.”
It is good that Tesla is rewarding those who learn from their mistakes with this shorter timeframe to lose the strikes. It won’t be needed forever, though, as eventually, the company will solve autonomy. The question is: when?

Elon Musk teases the capabilities of the Tesla Roadster once again

Elon Musk has once again teased the capabilities of the Tesla Roadster, fueling the anticipation that many have for the vehicle, despite it still having no public production or delivery date.
The Roadster is among the most anticipated vehicles in the automotive sector currently, and as Tesla has teased its capabilities, from a lightning-fast 1.1-second 0-60 MPH acceleration to potential hovering with cold-gas thrusters, people are eager to see it.
Although the design seemed to be finalized, there was still more work to be done. Earlier this year, as Tesla was showcasing some of the Roadster’s capabilities to Musk, he stated that it was capable of even more.
This pushed back its production date even further, much to the chagrin of those who have been waiting years for it.
Musk continues to tease us all, and as we sit here waiting hopelessly for it to be revealed, he said today that it is “something special beyond a car.”
The new Roadster is something special beyond a car
— Elon Musk (@elonmusk) September 17, 2025
Musk’s words were in response to a video posted by Tesla China, showing the Roadster in a new promotional video created by a fan.
The Roadster was planned to be released in 2020, but here we are in 2025, and there is still no sign of the vehicle entering production. However, Tesla did say earlier this year that it would host a demo event for the Roadster, where the company would showcase its capabilities.
Lars Moravy said earlier this year:
“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind-blowing; We showed Elon some cool demos last week of the tech we’ve been working on, and he got a little excited.”
Tesla exec gives big update on Roadster, confirming recent rumor
The delays have been attributed to “radically increased design goals” for the vehicle, which have, without a doubt, improved its capabilities, but at the same time, we just want to know if it’s ever going to come.
Tesla can always make it “better,” but at what point do you say, “Okay, it’s time to show this thing off.” They could always build another, even more capable supercar in the next ten years.
