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.

Elon Musk hints at when Tesla could reduce Safety Monitors from Robotaxi

Tesla could be reducing Safety Monitors from Robotaxi within ‘a month or two,’ CEO Elon Musk says.

Elon Musk hinted at when Tesla could begin reducing Safety Monitors from its Robotaxis. Safety Monitors are Tesla employees who sit in the front passenger seat during the driverless rides, and are there to ensure safety for occupants during the earliest rides.

Tesla launched its Robotaxi fleet in Austin last Sunday, and after eight days, videos and reviews from those who have ridden in the driverless vehicles have shown that the suite is safe, accurate, and well coordinated. However, there have been a few hiccups, but nothing that has put anyone’s safety in danger.

A vast majority — close to all of the rides — at least according to those who have ridden in the Robotaxi, have been performed without any real need for human intervention. We reported on what was the first intervention last week, as a Safety Monitor had to step in and stop the vehicle in a strange interaction with a UPS truck.

The Tesla and UPS delivery truck were going for the same street parking space, and the Tesla began to turn into it. The UPS driver parallel parked into the spot, which was much smaller than his truck. It seemed to be more of an instance of human error instead of the Robotaxi making the wrong move. This is something that the driverless cars will have to deal with because humans are aggressive and sometimes make moves they should not.

The Safety Monitors have not been too active in the vehicles. After all, we’ve only seen that single instance of an intervention. There was also an issue with the sun, when the Tesla braked abnormally due to the glare, but this was an instance where the car handled the scenario and proceeded normally.

With the Robotaxi fleet operating impressively, some are wondering when Tesla will begin scaling back both the Safety Monitors and Teleoperators that it is using to ensure safety with these early rides.

CEO Elon Musk answered the inquiry by stating, “As soon as we feel it is safe to do so. Probably within a month or two.”

Musk’s response seems to confirm that there will be fewer Teleoperators and Safety Monitors in the coming months, but there will still be some within the fleet to ensure safety. Eventually, that number will get to zero.

Reaching a point where Tesla’s Robotaxi is driverless will be another significant milestone for the company and its path to fully autonomous ride-sharing.

Eventually, Tesla will roll out these capabilities to consumer-owned vehicles, offering them a path to generate revenue as their car operates autonomously and completes rides.

For now, Tesla is focusing on perfecting the area of Austin where it is currently offering driverless rides for just $4.20 to a small group of people.

After months of declining deliveries and market pressure, Tesla appears to be regaining its footing in Europe. Tesla saw a significant spike in electric vehicle registrations across several key markets in June, signaling renewed momentum for the EV maker.

In countries like the UK, Spain, and the Netherlands, Tesla’s June sales surged significantly compared to May.

Explosive growth in the UK, Spain, and the Netherlands

Tesla’s most notable performance came in the United Kingdom, where June registrations jumped 224% month-over-month, and Spain, where registrations more than tripled. This made Tesla the top-selling electric car brand for the month in both countries, as per a CarUp report.

The Netherlands saw Tesla become the best-selling car brand in June across all vehicle segments. Tesla’s continued success in Norway also appears to be holding steady, though full figures for the market have not yet been finalized.

These numbers suggest Tesla’s European sales slump may have been temporary, with strong demand returning amid the ramp of the new Model Y, which was largely unavailable in the first quarter.

Mixed results in Sweden but signs of progress

In Sweden, Tesla’s performance remained mixed in June. While year-over-year registrations dropped over 70% in June, the company’s market share jumped 72% compared to May. Tesla now holds an 8.6% market share in the Swedish EV market, which means that one in every twelve new electric vehicles registered in the country last month was a Tesla, as per data compiled by eu-evs.com.

So far in 2025, Tesla ranks as the fourth-largest EV brand in Sweden, with 3,461 vehicles registered, trailing Volkswagen, Volvo, and Kia. The Tesla Model Y has remained a strong seller, ranking as the third most registered electric vehicle this year, behind the Volkswagen ID.7 and Volvo XC40, despite being largely absent in Q1 2025.

Just days after unveiling the Xiaomi YU7, a vehicle that is considered as the Model Y’s strongest competitor yet, Xiaomi CEO Lei Jun gave a nod of respect to Tesla and its Full Self-Driving (FSD) program. 

In a post on Weibo, Lei Jun highlighted the remarkable nature of Tesla’s first autonomous delivery. He also acknowledged that Xiaomi still has much to learn in the electric vehicle industry.

Xiaomi CEO’s Nod of Respect

Lei Jun’s comments about Tesla’s FSD delivery were shared as a response to Tesla VP Grace Tao’s post about the recent feat. The Tesla VP shared several key aspects of the delivery, from the fact that there was no driver in the Model Y to the vehicle reaching over 70 mph as it drove to its owner. 

“For the first time in history, the vehicle was delivered to the owner by itself. There was no driver or remote control throughout the journey, and the maximum speed reached 115 kilometers per hour, and it arrived safely at the customer’s door. This is a brand new Model Y. Tesla always surpasses imagination with disruptive innovation. A new era, exciting!” Tao wrote in her post.

In his response, the Xiaomi CEO acknowledged Tesla’s incredible feat. “Tesla is indeed amazing, leading the industry trends in many areas, especially FSD. We still have to continue learning!” he wrote.

Xiaomi’s Recent Tesla Competitor

The Xiaomi CEO’s comments show that Tesla’s projects and leadership garner a lot of respect in the global electric vehicle sector. While Tesla and Elon Musk tend to be media punching bags in the United States and Europe, the company and its CEO seem to be taken very seriously in China. This was despite China being the world’s most competitive electric vehicle market.

Xiaomi itself has become one of Tesla’s strongest rivals in China, with its first car, the SU7, bringing the fight to the Tesla Model 3. Its most recent vehicle, the YU7, could very well be the Model Y’s most legitimate rival yet, as it is more affordable, bigger, and more feature-laden than Tesla’s best-selling crossover. The YU7 has garnered quite a lot of attention, with Xiaomi receiving 200,000 firm orders for the vehicle within the first three minutes of its launch.
