For the first time, SpaceX has shipped a vacuum-optimized Raptor engine to its Boca Chica, Texas Starship factory days after the company’s present reiterated plans for an inaugural orbital launch attempt as early as July.

Back in March 2021, CEO Elon Musk confirmed that he’d set SpaceX a goal of attempting Starship’s first orbital launch no later than the end of July – around four and a half months distant at the time. Fifteen weeks later, though the prospects of an orbital launch attempt happening in July have practically shrunk to zero, SpaceX COO and President Gwynne Shotwell – best known for acting as a more grounded foil to Musk’s often impractical schedule estimates – reiterated that the company is still “shooting for July” for Starship’s first orbital launch attempt.

As of late June, hitting that target would require SpaceX to string together numerous extraordinary feats of engineering and rocketry in record time or attempt some extremely unorthodox corner-cutting.

The launch pad and launch vehicle hardware needed for Starship’s first space shot are currently far from ready for flight. On June 24th, Musk unexpectedly revealed that the Super Heavy booster prototype SpaceX is now in the late stages of assembly isn’t actually the booster that will carry Starship on its first space launch attempt. In other words, though dozens of rings in various states of work are strewn about SpaceX’s Boca Chica factory, the company has yet to begin assembling the massive 65m (~215 ft) tall booster required for the first orbital launch attempt.

Elon Musk says SpaceX’s second Starship booster prototype is almost finished

Using Super Heavy Booster 3 (B3) as a ruler, assembly could easily take 9-10 weeks – starting whenever the process actually begins. If SpaceX started stacking Booster 4 today, in other words, it’s unlikely that the rocket would even be complete by the end of August. Barring SpaceX taking unprecedented shortcuts, completing the booster is just part of the process of preparing for flight and B4 would still need to be qualified for flight, likely involving at least one cryogenic proof and static fire test.

In a best-case scenario where SpaceX begins assembly today, manages to halve Booster 4 assembly time in one fell swoop, the sneaks the second Super Heavy ever completed through qualification testing in a single week, the orbital flight test booster still wouldn’t be ready for Starship installation (likely another unprecedented first) before mid-August.

That would then leave SpaceX five or six weeks to fully assemble Starship S20, a process that has yet to begin. Like Starship SN15, which Musk said sported “hundreds of improvements”, Musk has also stated that Ship 20 and all after it will feature another batch of upgrades needed to take Starship orbital. Starship SN15 was very gradually stacked and assembled over the course of almost four months, though that slow assembly can likely be blamed on the fact that SpaceX is busy testing Starships SN8 through SN11 and was effectively waiting to see if any other major changes might be required.

While most of S20’s upgrades are a mystery, the ship’s thrust dome – spotted in work at Boca Chica earlier this month – has already confirmed that the prototype will be the first with the necessary hardware for Raptor Vacuum engine installation. That likely means that S20 will also be the first Starship to attempt to static fire six Raptor engines*, potentially producing more thrust than a Falcon 9 booster. On June 27th, one such vacuum-optimized Raptor (RVac) arrived in Boca Chica for the first time ever, making it clear that the comparatively brand new engine may already be ready to start integrated Starship testing.

*Update: SpaceX CEO Elon Musk says that the Raptor Vacuum delivered to Boca Chica on June 27th is, in fact, meant for Starship S20, seemingly confirming that the prototype will fly with a full six Raptor engines.

Of course, beyond Starship and Super Heavy, SpaceX also has a great deal of work left to get the rocket’s first orbital-class launch facilities partially operational. SpaceX will need to complete and activate at least one or two more custom-built propellant storage tanks, sleeve those three or four tanks with three or four massive thermos-like ‘shells,’ complete thousands of feet of insulated plumbing and wiring, finish a massive ‘launch table,’ install that table on a six-legged ‘launch mount;’ outfit that table and mount with an array of power, avionics, hydraulics, and fueling equipment and plumbing; complete a ~145m (~475 ft) ‘integration tower,’ and perform the first fit checks and shakedown tests with a real booster or Starship.

Only then will SpaceX be able to attempt Starship’s first space launch. All told, it might not be literally impossible for SpaceX to complete all the above work in less than five weeks, but it’s safe to say that the odds of that happening could probably make a lottery ticket blush. Regardless, if Starship reaches orbit at any point before the end of 2021, it would beat out simpler “next-generation” rockets like Ariane 6, ULA’s Vulcan, and Blue Origin’s New Glenn despite beginning concerted development years later and with a far less certain funding situation.

Tesla Semi gets new adoptee in latest sighting

Tesla is continuing to increase the number of companies that have access to the Semi.

The Tesla Semi looks to have its newest adoptee as US Foods, the second-largest foodservice distributor in the United States, was seen with its badging on the all-electric Class 8 truck.

US Foods trails only Sysco Corporation in terms of foodservice distributors by volume in the United States. The company joined several other massive food industry entities, such as PepsiCo, and its subsidiary, Frito-Lay, have both utilized the Tesla Semi in their fleets.

Tesla Semi futuristic sci-fi acceleration sound will never get old

The Semi in question was spotted by X user Zanegler, a prominent tracker of the Tesla Semi and its factory, which sits near the company’s Gigafactory Nevada plant in Reno:

US Foods also has a distribution center in Reno, which could have something to do with its decision to start using the Semi in regional logistics.

With an influx of EV semitrucks hitting the market from many different manufacturers, it is evident that companies are taking the idea of making their fleets more environmentally friendly very seriously.

Tesla is still very close to unloading the Semi in a more volumized fashion, as the company’s Vice President of Vehicle Engineering, Lars Moravy, said in January:

“We just closed out the Semi factory roofing walls last week in Reno…but we’re prepping for mechanical installation of all the equipment in the coming months… The first builds of the high-volume Semi design come late this year in 2025 and begin ramping early in 2026.”

First Tesla Semi high-volume production builds expected this 2025

With the latest addition of US Foods, Tesla increases its list of companies that are planning or are already using the Semi to help with local logistics and transportation. Among them are:

  • PepsiCo
  • Walmart
  • Sysco
  • Costco
  • Martin Brower
  • Saia Inc.
  • UPS
  • Anheuser-Busch
  • DHL

Many other companies have plans to use the Semi in their fleets. Currently, Tesla appears to be hand-picking those who have access to the vehicle as the pilot program continues.

Tesla Cybertruck takes a bump from epic failing Dodge Charger

The Cybertruck seemed unharmed by the charging Charger.

There comes a time in a driver’s life when one is faced with one’s limitations. For the driver of a Dodge Charger, this time came when he lost control and crashed into a Tesla Cybertruck–an absolute epic fail. 

A video of the rather unfortunate incident was shared on the r/TeslaLounge subreddit.

Charging Charger Fails

As could be seen in the video, which was posted on the subreddit by Model Y owner u/Hammer_of_something, a group of teens in a Dodge Charger decided to do some burnouts at a Tesla Supercharger. Unfortunately, the driver of the Charger failed in his burnout or donut attempt, resulting in the mopar sedan going over a curb and bumping a charging Cybertruck.

Ironically, the Dodge Charger seemed to have been parked at a Supercharger stall before its driver decided to perform the failed stunt. This suggests that the vehicle was likely ICE-ing a charging stall before it had its epic fail moment. Amusingly enough, the subreddit member noted that the Cybertruck did not seem like it took any damage at all despite its bump. The Charger, however, seemed like it ran into some trouble after crashing into the truck.

Alleged Aftermath

As per the the r/TeslaLounge subreddit member, the Cybertruck owner came rushing out to his vehicle after the Dodge Charger crashed into it. The Model Y owner then sent over the full video of the incident, which clearly showed the Charger attempting a burnout, failing, and bumping into the Cybertruck. The Cybertruck owner likely appreciated the video, in part because it showed the driver of the Dodge Charger absolutely freaking out after the incident.

The Cybertruck is not an impregnable vehicle, but it can take bumps pretty well thanks to its thick stainless steel body. Based on this video, it appears that the Cybertruck can even take bumps from a charging Charger, all while chilling and charging at a Supercharger. As for the teens in the Dodge, they likely had to provide a long explanation to authorities after the incident, since the cops were called to the location.

Tesla confronts Service complaints with new AI-backed strategy

Tesla will use a new AI Agent to help expedite Service claims and improve communication with customers.

Tesla is implementing a new AI-based strategy to improve service for owners. Service has routinely been among the biggest complaints of owners, although it has improved drastically over the past few years.

Some of the complaints that Tesla has received regarding its Service platform have evidently been used to develop new strategies to not only streamline the entire experience but also to make things easier for the company, which deals with many claims each week.

As a result of complaints in the past, Tesla has used various strategies to make things better for customers. However, the latest improvement comes as a result of AI, something Tesla leans on in many facets of its business.

Tesla adds ingenious solution to app to streamline Service appointments

Tesla’s AI and IT Infrastructure, Cybersecurity, and Vehicle Service head Raj Jegannathan said on X this week that the company is rolling out a new AI Agent specifically designed to handle service comms with customers.

He said the new Service AI Agent will detect delays in communications between the company and the customers, monitor the sentiment of these conversations, and auto-escalate certain claims directly to leaders.

It will also allow customers to type the word ‘Escalate’ in the message center portion of the phone app after two weeks of delays. This will help customers reach higher-ups more easily and likely will eliminate the complaints that many have had over the past few years.

The company is rolling out the AI Agent in ten pilot locations to start. Its first day being active was May 8.

Jegannathan said:

“Tesla Service’s new AI Agent detects comms delays, monitors sentiment, & auto-escalates to leaders. Starts tomorrow at 10 pilot locations. In 2 weeks, type “Escalate” in ‘message center’ to reach managers. Guardrails in place to prevent abuse. We’ll keep improving!”

Service has had a lot of interesting strategies used to improve things, but it has definitely been a weak point of the Tesla ownership experience. In a perfect world, vehicles wouldn’t need repair for anything, but that is not realistic.

Instead, Tesla has worked to expedite the entire Service experience through various strategies, including F1-style service, and a goal to fix two-thirds of repair claims within the same day.

Parts availability sometimes takes this goal out of reasonableness, but these constant attempts at improving the repair experience show Tesla is doing what it can to make things better for owners.
