A SpaceX Super Heavy booster prototype has survived its first major test seemingly without issue, potentially opening the door for a static fire test with several Raptor engines as early as this week.

Not long after the latest line of propellant storage implements was transported from SpaceX’s Boca Chica, Texas factory to Starship’s first orbital launch pad, the company officially closed the one highway to the pad and nearby beach. By ~4:30pm CDT (UTC-5), the first major test of an integrated Starship booster was under way and clouds of cryogenic vapors were pouring off of Super Heavy B3’s thrust (aft) dome as the humid air came in contact with steel cooled to around –330°F (–200°C).

While technically known as a cryogenic proof test, Booster 3’s first major challenge looked more like a basic pressure test. Curiously, only small amount of frost – the telltale sign of a ‘cryo proof’ – formed on the outside of Super Heavy’s ~65m (~215 ft) tall propellant tanks in two hours of activity, indicating that SpaceX likely chose a more cautious approach to Booster 3’s first cryo proof.

In short, Booster 3 was likely filled with a few hundred tons of liquid nitrogen relative to the more than 3000 tons its tanks could easily hold and the fraction of that total capacity SpaceX’s suborbital launch site can actually supply. Teams have been working around the clock for months to outfit Starship’s first orbital launch site with enough propellant storage for at least one or two back to back orbital launches – on the order of 10,000 tons (~22M lb) – but the nascent tank farm is far from even partially operational. That’s left SpaceX with its ground testing and suborbital Starship launch facilities, which appear to be able to store around 1200 tons of propellant.

Assuming the suborbital pad’s main liquid oxygen and methane tanks can also both store and distribute liquid nitrogen, which isn’t guaranteed, SpaceX thus has the ability to fill approximately 30-40% of Super Heavy B3’s usable volume. Frost lines aren’t always a guaranteed sign of fill level but if they’re close, SpaceX likely filled Booster 3’s tanks just 5-10% of the way during the rocket’s first cryoproof.

Based on loud, visible venting that occurred throughout the process, it’s likely that Super Heavy’s first cryo proof was more focused on pressure testing with just a small taste of the true thermal shock, loads, and general mechanical stress Starship boosters will have to withstand when loaded with thousands of tons of propellant and generating thousands of tons of thrust with dozens of Raptor engines.

Following July 12th’s test, Super Heavy B3’s next steps could either be one or several additional cryo proofs or a static fire test with an unknown number of Raptor engines installed. The booster completed Monday’s testing with one Raptor installed, while the most engines ever tested simultaneously is three. SpaceX has yet to update backup test windows scheduled from noon to 10pm CDT on July 13th, 14th, and 15th, any of which could be used for additional cryo proof or static fire testing.

Tesla is opening Cybercab rides to a select few

Tesla has opened a new sweepstakes to allow the public to be among the first to take an initial ride in a Cybercab. This all-electric, steering-wheel-less, pedal-less vehicle is the centerpiece of the company’s autonomous ride-hailing platform, Robotaxi.

There are two ways Tesla fans can get to Austin to take part in the first public rides of the Cybercab: by riding on the Robotaxi platform by August 23, or by mailing a very specific entry to their Headquarters at Gigafactory Texas.

Tesla announced the latter portion of the sweepstakes last night:

Tesla will give one entry into the sweepstakes if you mail a 3″ by 5″ piece of paper with your full name, mailing address, telephone number, email address, and date of birth to their address:

Tesla, Robotaxi Sweeps Event

1 Tesla Road,

Austin, TX 78725

There is a limit of one entry per stamped envelope. You can send as many as you’d like, but they must be in separate envelopes.

The company’s unique strategy to give people the opportunity to ride in a Cybercab before pretty much anyone else outside of the company is a hilarious but spot-on representation of how Tesla operates. In classic fashion, they had the perfect response to the event:

Cybercab will launch later this month, it appears, especially as it plans to announce the winners of the sweepstakes on August 25. The car has already been operating internally, as employees have been able to utilize the Cybercab for rides in some capacity, something it announced earlier this month.

Tesla weirdly confirms Cybercab employee rides, a huge milestone

Moving forward, the big goal is to get Cybercab out on the roads and integrated into the public Robotaxi fleet, one that will pick up real-world ride-hailers and give them a ride from Point A to Point B.

No matter which way you cut it, it appears Tesla is close to putting a vehicle with no steering wheel and no pedals on the road to help people travel autonomously.

You can ride along with us in our first Cybercab ride from the We, Robot event in October 2024. The video is embedded below:

Tesla reveals plans for Robotaxi charging hub in Austin

Tesla has revealed plans through permit submissions for a massive Robotaxi charging hub in Austin, Texas.

Tesla plans to build the Supercharger hub in multiple phases, with the second phase potentially introducing wireless induction charging, something the company has been developing for the Robotaxi fleet.

Initially, 48 Tesla Robotaxi-geared Superchargers will be built on a lot just across from the St. Elmo, Texas, Service Center. There are about 80 additional spots that will not be impacted by phase 1 of the construction process.

Filings show that the second phase of the project will turn those 80 additional spots into wireless charging for Robotaxi, but it might be an error. The Key Notes state that item 3 is listed as “V4 Charging Cabinet to Support 80 Wireless Chargers in Phase 2. However, the drawings point to V3 Cabinets that are already tied to Superchargers:

There are roughly 128 total spots in the lot, but it is unclear if they will all be used for charging based on what appears to be some sort of typo in the blueprint.

This is among the first Robotaxi charging hubs Tesla has started to develop, as it currently has four others planned throughout various areas: one in Phoenix, one in San Antonio, another in Irving, which will serve the Dallas-Fort Worth area, and another in Las Vegas.

These projects are necessary as Tesla expands its Robotaxi program. Now that preparations have started for the public launch of Cybercab, Robotaxi will likely be expanding aggressively, especially over the next two to three years.

Last night, The Information reported that Tesla was planning to launch Cybercab as soon as the end of August. Hours later, Tesla then announced it was launching a competition for fans to potentially ride in Cybercab during its first public rides.

Tesla Cybercab launch preparations have begun

Tesla’s plan to expand its charging infrastructure in the regions where Robotaxi will initially operate is great preparation for the expanding service. There is still a lot to do, including launching the Cybercab on time.

Tesla got its largest order for the all-electric Class 8 Semi yet, a 500-unit order from Einride AB, a Swedish trucking company.

Einride made the announcement this morning following its second-quarter earnings call. The company said it plans to use 500 Tesla Semi units on its fleet intelligence platform, called Saga AI. The deployments will serve large companies like Amazon and will extend Einride’s electric freight network across logistics routes in California, New Jersey, Texas, Illinois, and Georgia.

The deployment is being carried out in several phases over the next two years as Tesla ramps production of the Semi at its dedicated production facility in Sparks, Nevada. Einride will receive its first Semi units in September.

Saga AI

Saga AI is Einride’s dedicated fleet intelligence platform. It enables scaled adoption of electric trucks for freight use and allows shippers to integrate electric capacity without the operational burden or capital risks of managing a fleet. This helps integrate cost-efficient logistics and makes budgeting and forecasting much more accurate.

Tesla Semi’s Adoption

The Tesla Semi is now gathering large-scale clients past those who have helped the company operate a Pilot Program to gain initial information and feedback from real-world drivers.

Perhaps the biggest and most notable is that of Frito-Lay and PepsiCo., who have worked with Tesla for the past several years to dial in the finer details of the truck, including its efficiency and operation-related components.

Tesla Semi gets strange-but-understandable comparison from Jay Leno

There has been tremendous progress in that time, and it even catalyzed Tesla to make some design changes, which were unveiled earlier this year.

But Einride CEO Roozbeh Charli says his company’s partnership with Tesla will continue to push those things forward:

“This deployment is yet another proof point that we can execute at the scale our customers demand. Working closely with Tesla to bring next-generation Semis into active operations quickly and at scale is a testament to the strength of that partnership, and how quickly this technology is maturing from promise to daily operations.”

Tesla Semi is already winning over truck drivers

Additionally, Dan Priestley, the Director of the Semi Program at Tesla, said the partnership is ideal due to Einride’s focus on sustainable transport:

“Einride is at the forefront of sustainable freight, and we are thrilled to deepen our relationship with them through this order of 500 Semis. EV heavy trucks provide lower costs per mile from fuel savings, reduced maintenance, and better uptime over diesel trucks. These savings increase further through operational efficiency when deploying EV trucks at scale, and we are excited that Einride recognizes this and look forward to supporting their deployments.”
