A SpaceX Falcon 9 booster had all four of its landing legs successfully retracted after a flawless fourth launch and landing, highlighting the impressive margins and durability of the rocket’s upgraded Block 5 design.

On April 22nd, Falcon 9 booster B1051 lifted off on its fourth orbital-class mission – also its second 60-satellite Starlink launch this. Around eight minutes later, B1051 successfully landed aboard drone ship Of Course I Still Love You (OCISLY), ending a back-to-back streak of failed ocean recoveries for SpaceX and verifying that the cause of a March 2020 in-flight engine failure had been rectified. After the loss of booster B1056 and B1048 in February and March, it was also simply a relief to have B1051 safe and sound aboard OCISLY, ensuring that the rocket should be able to support another launch in the near future.

After sailing in port on April 26th, SpaceX technicians lifted a booster off of drone ship OCISLY’s deck for the first time since late January – coincidentally (or maybe not) also Falcon 9 B1051. Two days after its arrival in port and transfer onto dry land, SpaceX successfully retracted all of the massive booster’s landing legs in less than three hours and had it ready for transport less than two hours after that. While B1051’s brisk fourth recovery didn’t break any records, it still serves as a reminder of Falcon 9’s impressive durability in light of the landing it experienced just ~85 days prior.

B1051’s successful leg retraction after its fourth launch and landing is particularly impressive for one main reason: after its third launch, the booster suffered perhaps the hardest drone ship landing any Block 5 rocket has thus far experienced.

Taken in March 2019 and February 2020 after Falcon 9 B1051’s first and third launches and landings, the photo below reveals just how hard a landing B1051 experienced after its Starlink-4 launch. Built almost entirely out of carbon fiber composites and mounted directly to the rocket’s tank walls, Falcon’s telescoping landing legs rely on something known as a ‘crush core’ – made out of aluminum honeycomb – that’s designed to intentionally collapse under a very specific amount of stress.

The crush core is situated in the very tip of the cylindrical leg booms and is easily visible above on the left, while it has nearly disappeared in the right (after) photo after an exceptionally hard landing used up what looks like 90+% of the booster’s safety margin. In other words, if B1051 had landed just a little harder after its third launch, it’s possible that the booster’s landing leg booms would have used up all their crush cores and been driven into the kerosene tank they attach to, potentially totaling the Falcon 9 first stage.

Instead, while clearly a rough landing, B1051 appears to have had its landing leg crush cores replaced and was made ready for another Starlink launch less than three months after that exceptionally hard landing. In other words, despite the rarity of similar hard landings over dozens of recent booster landings, SpaceX was apparently almost entirely unconcerned about the rocket’s state.

As usual, the company almost certainly checked the structural integrity of B1051’s major welds and landing leg hardware before certifying the vehicle for its fourth launch, but the fact that its reuse was so seemingly unexceptional is a testament to the sheer durability of SpaceX’s reusable rocket boosters. Thanks to the modularity of its design, B1051 should have no trouble performing at least several more orbital-class launches over the next several months (if not years). More likely than not, the Falcon 9 Block 5 rocket will fly again just two or so months from now on another Starlink mission, of which SpaceX has 20+ nominally scheduled this year alone.

Tesla rival’s CEO makes shock suggestion to customers about Model Y

“The Model Y is a great car, and Tesla also announced a number of promotions yesterday, so you might want to consider it.”

Tesla rival Xiaomi is experiencing demand that is off-the-charts with its new YU7 crossover, which competes with the Model Y. The company’s CEO has stated that demand is truly outpacing what it can build, and that customers in limbo should consider the Model Y because “it’s a great car.”

The Xiaomi YU7 has already gained an incredible number of orders so far. Its launch a few months ago had consumers busting down doors to place an order before others, and demand has been so high that customers will wait, on average, between 56 and 59 weeks for delivery.

Tesla Model Y meets new competition from Xiaomi 

Within 18 hours, Xiaomi received about 240,000 orders, CarScoops reported. Some customers are truly interested in the vehicle, but cannot wait the extended period to take delivery as they might need a car now.

Xiaomi CEO Lei Jun said on social meida that there are other cars out there that would be suitable as a replacement to the YU7:

“If you need to buy a car quickly, other China-produced new energy vehicles are pretty good.”

He explicitly mentioned the Model Y, Xpeng G7, and Li Auto i8.

Regarding the Model Y, he said:

“The Model Y is a great car, and Tesla also announced a number of promotions yesterday, so you might want to consider it.”

The Model Y has been the best-selling car in the world over the past two years, and it still leads in many markets as the most sought-after EV. However, in China, there are so many formidable competitors that customers are seemingly going for whatever they can get to first.

Of course, a car is a car, but Tesla has gained a more notable reputation for its industry-leading tech and driver assistance systems, including City Autopilot, which has been used in China for a few months now.

Tesla offers tasty Supercharging incentive as Q3 push continues

Tesla is offering a tasty Supercharging incentive on inventory Model 3 units in Canada as it continues to push sales in the third quarter.

In the United States, Tesla is preparing for the end of the $7,500 electric vehicle tax credit. While it is offering a multitude of incentives in the U.S. to help push sales of its vehicles before the credit goes away, it is not saving the deals for Americans exclusively.

Yesterday, the company announced it is now offering Free Supercharging for life on all Model 3 inventory in Canada, a massive incentive for those who would use the vehicle as a daily driver:

The deal would normally only apply to Superchargers located in Canada, meaning if a Canadian drove over the border into the United States and Supercharged, they would have to pay for it.

However, Tesla also confirmed that the charging deal would extend to the U.S. Canadians will be able to drive across the U.S. and Supercharge for free for the life of the vehicle.

Free Supercharging is such a great perk because the money an owner saves on charging factors directly into what they are saving if they were to own a gas car. While Supercharging and home charging are, on average, cheaper than filling up with gas, the savings are not massive.

When Supercharging is free, it can save consumers hundreds of dollars per month, especially if they plan to use the Tesla for their daily commute. Some people could fill their gas cars up two times a week to get to work, spending $80-$100 every five days on gas.

Tesla has been using incentives like this to push vehicles into customers’ hands. Q3 could be one of the best three-month spans in recent memory with the push it is making.

Tesla is preparing to take on autonomy’s final boss

India’s city streets are notorious for their complexity and congestion.

If there is any sign that Tesla is now confident about its self-driving program, it would be this. As could be seen on Tesla’s Careers page, the company is now hiring Autopilot Vehicle Operators in Delhi and Mumbai, India. 

As far as real-world traffic is concerned, one could argue that India’s city streets are the final boss of autonomous driving systems due to their complexity and congestion.

Tesla job openings

As per Tesla in its recent job openings, Prototype Vehicle Operators will be responsible for driving an engineering vehicle for extended periods and conducting dynamic audio and camera data collection for testing and training purposes. In both its job listings for Mumbai and Delhi, Tesla noted that successful applicants will be gathering real-world data on the weekends and around the clock. 

Considering the job openings in India, Tesla seems to be intent on rolling out its advanced driver-assist systems like FSD in the country. This is quite interesting, as Tesla is not hiring Prototype Vehicle Operators in other territories that recently launched, such as the Philippines. Perhaps Tesla intends to tackle FSD’s final boss of sorts before rolling out FSD in other territories.

FSD’s rollout

Tesla’s autonomous driving program uses the company’s Full Self-Driving system, which is currently available on vehicles in North America and China. Tesla, however, has a more advanced version of FSD called Unsupervised FSD, which is currently being used in vehicles that are part of the Robotaxi pilot in Austin and the Bay Area.

Elon Musk has also recently announced on X that Tesla will be releasing FSD V14 in the coming weeks. He also shared a number of improvements that can be expected from FSD V14. “The FSD release in about 6 weeks will be a dramatic gain with a 10X higher parameter count and many other improvements. It’s going through training & testing now. Once we confirm real-world safety of FSD 14, which we think will be amazing, the car will nag you much less,” Musk wrote in his post.
