Just a few days after CEO Elon Musk said that SpaceX’s first true Super Heavy prototype was “almost done,” the booster has been stacked to its full height.

Standing more than 65 meters (~215 ft) tall, Super Heavy Booster 3 (B3) assembly is now just a few major welds away from completion after SpaceX teams mated the final two sections of its propellant tanks and structure. Assembled separately out of approximately 12 barrel sections each made up of 2-4 steel rings, Booster 3’s methane tank (13 rings) and oxygen tank (23 rings) were stacked together on June 29th, just over six weeks after the process began.

Earlier the same day, speaking at the 2021 Mobile World Congress, Musk confirmed what was now fairly clear to most observers, stating that SpaceX is “going to do its best” to complete Starship’s first orbital (or, at least, space) launch attempt “in the next few months.” In other words, a several-month-old launch target of no later than July 2021 is most likely out of reach despite a strong effort from SpaceX.

The most significant technical hurdles still in the way involve a few incremental Starship milestones and, more importantly, the qualification of the largest and most powerful rocket booster ever built. Standing almost as tall as an entire two-stage Falcon 9 or Falcon Heavy, Super Heavy is expected to weigh more than 3500 tons (~7.7 million lbs) and produce at least ~5000 tons (~11 million lbf) of thrust at liftoff – more than any other rocket booster in history, liquid or solid.

Borrowing heavily from Starship, Super Heavy is mostly built with the same techniques out of the same steel rings, stringers, and structures, save for a few booster-specific components. However, Super Heavy is also designed to use 29-32 Raptor engines while the most SpaceX has ever simultaneously installed, tested, or flown is three. In other words, while Super Heavy is in many ways simpler than Starship, it will still be treading plenty of new ground when it heads to the launch pad for the first time.

Plenty of final integration tasks remain before Super Heavy B3 will be ready to start qualification testing but SpaceX could feasibly be ready to roll the booster to the launch site within the next week or two. Once installed on a former Starship launch mount that’s been customized for booster testing, Super Heavy will likely be put through its first cryogenic proof and static fire test(s) to verify that the massive rocket is performing as expected. The static fire process could be fairly lengthy if SpaceX decides to incrementally increase the number of Raptor engines installed.

In the likely event that Booster 3 begins testing without engines installed, SpaceX will also have to go through the process of installing up to 29 Raptors while Super Heavy is sitting out in the elements on a launch mount. Based on experience with Starship, installing that many engines in situ could take at least several days – and maybe longer. All told, the fun is only just beginning.

California proposal to allow self-driving tests for heavy-duty trucks

Published

Tesla-semi-production-ramp-2023

A new proposal in the state of California would allow initial testing of self-driving heavy-duty trucks, as Tesla and others aim to bring their driverless technologies to market with Class 8 trucks and other large vehicles.

On Friday, the California Department of Motor Vehicles (DMV) said that it’s proposing self-driving vehicle tests be allowed on public roads for heavy-duty trucks and other large vehicles, as detailed in a report from Reuters. The news comes as heavy-duty vehicles about 10,001 pounds are currently unable to utilize public self-driving tests in California, as well as others such as Texas, Arizona, and Arkansas.

The proposal would restrict autonomous testing for semi-trucks and other oversized vehicles to specified, pre-selected routes that would be pre-determined to be legal for size, weight, and loading requirements. It would also ban testing these vehicles on city streets, with selected routes primarily including major highways.

The state would also prohibit testing of specific heavy-duty vehicles until further notice under the proposal, including household movers, commercial vehicles used to transport passengers, oversize loads, bulk liquids, or hazardous materials.

The DMV plans to hold a public hearing on the proposal on June 10, after which point it would be allowed to move forward with the agency.

California has been preparing regulations for autonomous trucking since at least last August, when the state submitted an initial draft for such a legal framework.

The state is also evaluating whether light-duty vehicle testing requirements should be updated. Currently, the state requires a permit to test self-driving vehicles utilizing a safety driver, before applying for subsequent phases of driverless testing and deployment permits.

To apply for driverless testing permits, manufacturers are required to conduct testing for a minimum of 50,000 miles, while heavy-duty manufacturers would be required to complete at least 500,000 autonomous testing miles under the proposal. Of them, up to 40,000 of the miles are allowed to be completed outside of California.

The news also follows the Trump administration’s aims to accelerate self-driving deployment this week through the expansion of exemptions for certain reporting requirements.

Although Tesla’s Full Self-Driving (FSD) is not currently available for the company’s electric Semi, it’s expected to become available at some point in the future. Tesla has also been spotted testing its FSD on the Semi in and around Giga Nevada, ahead of the company’s plans to launch the software on the Class 8 truck.

Tesla is currently aiming to ramp up production of the Semi, and it’s constructing an expansion to its Gigafactory in Nevada to eventually scale up to volume production.

Tesla reservation emails hint at imminent launch in India

Tesla appears to be nearing the launch of vehicle sales in India, as hinted at in a recent correspondence with early reservation holders.

Published

on

A report this week says that Tesla has sent out a new batch of emails to some of its earliest reservation holders in India, suggesting that the company’s highly anticipated launch of electric vehicles (EVs) in the country could be imminent.

As seen in emails viewed by Bloomberg in a Friday report, Tesla has begun refunding early reservation holders in India, indicating that the U.S. automaker seems to be nearing its official debut in the country. Some Model 3 reservation holders in India initially paid deposits to purchase a Tesla as early as 2016, and they come due to the company having refreshed the vehicle’s design last year.

“We would like to return your reservation fee for the time being,” Tesla writes in the email. “When we finalize our offerings in India, we will reach out in the market again. We hope to see you back with us once we are ready to launch and deliver in your country.”

The launch is thought to be highly consequential for Tesla, as India is the world’s third-largest auto market, and thousands of people in the nation are employed by vehicle and component manufacturing facilities. However, years of talks between Tesla and the government about launching sales and potentially a factory there have hit a standstill multiple times, largely due to disagreements over the country’s high import duties.

While many are speculating as to when exactly Tesla could launch vehicle sales in India, several other indicators have also suggested that the maker is getting close to doing so.

Last weekend, a Tesla Model Y with a privacy wrap was seen being tested in India, marking the second such sighting to take place in the past few weeks. The company also officially began the certification and homologation processes for the new versions of both the Model Y and Model 3 in India last month, and it has been hiring and picked out two sites for initial stores in the country, the first in Mumbai and a second in New Delhi.

A Bloomberg report in February also claimed that Tesla was aiming to sell vehicles in India around the third quarter of the year, though models being sold in the country had not yet been revealed at the time.

Tesla’s Superchargers in North America opening to non-Tesla EVs

Along with allowing Tesla’s vehicles to charge at Supercharger stations, the company has slowly been rolling out access to other, non-Tesla electric vehicle (EV) brands in North America over the past several months. For example, Superchargers opened to Kia’s EVs in North America on Thursday, increasing the company’s chargers to the over 40,000 DC fast-charging stations and doubling the number of stations owners of the car brand can use.

Other brands with access to Tesla’s Superchargers include Kia parent company Hyundai, Ford, GM, Genesis, Lucid, Mercedes, Nissan, Polestar, Rivian, and Volvo, and Volkswagen and subsidiary Audi are the next brands in line to gain access.

Tesla also runs three-month Supercharger voting periods for owners to cast votes on where they’d like to see new Superchargers built, and the company recently opened its voting round for the second quarter along with revealing the winning locations from Q1.
