SpaceX appears to have successfully fired up its fourth full-scale Starship prototype for the third time, although the Raptor engine test ended with the aft end of the ship catching fire and burning for quite some time.

Around May 7th, hours after Starship SN4 completed its second wet dress rehearsal and Raptor static fire in ~24 hours, SpaceX removed the SN18 Raptor engine it had used to support those tests, transporting it back to storage facilities a mile down the road. Three days later, SpaceX sent Raptor SN20 down the same same road and installed it on Starship SN4 – a swap made for unknown reasons.

Regardless, that swap meant that SpaceX would need to perform at least one more static fire test to prove that Starship and its new Raptor engine were getting along before the company could proceed to hop test preparations. After several days of at least 4 aborted Starship static fire attempts, SpaceX has finally managed to fuel Starship SN4 and ignite Raptor engine SN20 – but not before a new challenge cropped up.

Just shy of 1:01 pm CDT (18:01 UTC), Starship SN4 appeared to successfully fire up Raptor SN20 for at least several seconds, serving as an in-situ acceptance test for the advanced rocket engine. Like the Merlin 1D engines that power Falcon 9 boosters, Raptors are built in Hawthorne, California, shipped to McGregor, Texas for standalone acceptance testing, installed on their assigned rocket, and static fired one more time before SpaceX deems them ready for launch.

This static fire thus served to verify that Starship SN4 and Raptor SN20 were both still in good health after a busy week of numerous tests and several weeks or months in storage, respectively. If fully successful, it would likely clear Starship SN4 to attempt what would be the inaugural flight of a full-scale Starship prototype, potentially ready to occur as early as May 21st (pending an FAA license, of course). Unfortunately, when Raptor SN20 ignited, it appeared to shake or overpressurize one or several plumbing lines, catching what must have been a methane vent or drain line on fire.

While the rocket itself is likely totally fine, much like its Starhopper predecessor suffered even worse fires during its summer 2019 test campaign, the dark smoke that appeared shortly after the secondary fire started is not a great sign. As methane and oxygen burn quite cleanly, that smoke likely means that the fire(s) got to some of the extensive wiring covering Starship and connecting to its test stand and ground controllers. If damaged, all of that wiring will need to be replaced, while the leaky methane pipe that burned for a solid 15 minutes will also need to be fixed.

As such, it’s likely that Starship SN4 will need to wait at least several more days – and may even need to complete a fourth static fire test – before SpaceX can clear it for an inaugural 150m (~500 ft) hop test.

Tesla lands new partnership with Uber as Semi takes center stage

Tesla and Uber will work together, using the company’s all-electric Semi, to make sustainable Class 8 electric trucks more affordable with three main strategies: Subsidized Pricing, Predictable Growth, and Optimization of Utilization.

The Tesla Semi has led to a new partnership between the company and Uber, as the two are launching a program that aims to revolutionize logistics by making sustainable commercial vehicles more accessible.

Uber announced on Tuesday that it was planning to launch the Dedicated EV Fleet Accelerator Program in a new partnership with Tesla. Uber’s Freight division is mainly responsible for the new program, which it calls a “first-of-its-kind buyer’s program designed to make electric freight more affordable and accessible by addressing key adoption barriers.”

Tesla and Uber will work together, using the company’s all-electric Semi, to make sustainable Class 8 electric trucks more affordable with three main strategies: Subsidized Pricing, Predictable Growth, and Optimization of Utilization.

  • Subsidized Price: Fleets purchasing Tesla Semis through this program will receive a subsidy on the purchase price.   
  • Predictable Growth: Fleets will integrate their Tesla Semis into Uber Freight’s dedicated solutions for shippers for a pre-determined period. This creates an opportunity for carriers to forecast revenue with confidence, while shippers gain consistent access to reliable, zero-emission capacity. 
  • Optimize Utilization: Uber Freight taps into its extensive freight network to match carriers with consistent, high-quality freight from our strong shipper base—helping ensure the addition of these Tesla Semis stay fully utilized and carriers see dedicated, real, measurable returns from the start

Tesla will work directly with interested companies to iron out technical details about the Semi, as well as its cost of ownership based on the tailored needs of their business. Fleets can expect savings on the first day, Uber says, as they will avoid diesel fuel costs and reduced maintenance, a widely known advantage of EVs.

Uber announced that it had partnered with select carriers to pilot the Dedicated EV Fleet Accelerator Program prior to its launch:

“During the 2-month pilot program, the Tesla Semis showcased both reliability and efficiency for Uber Freight’s shipper network. Over 394 hours of drive time, carriers covered 12,377 miles. With an average net energy consumption of just 1.72 kWh per mile and only 60 hours of total charge time, these results highlight the operational viability of Tesla Semis on demanding freight lanes. “

In its press release launching the program, Uber effectively highlights how the use of the Semi can impact a company’s margins and profitability through fuel savings, reduced maintenance costs, and lower total cost of ownership.

This is something that turns so many people away from gas cars and toward EVs, so it’s no surprise that Uber wanted to emphasize this point on a larger scale with a company that utilizes a fleet of vehicles.

Tesla has been experimenting with a select group of companies, as well. It partnered with PepsiCo. several years ago, in an effort to launch a pilot program for the Semi. It had excellent results, showing higher efficiency, lower costs, and an exceptional ability to handle long runs.

Drivers have had a lot of positive things to say:

The Semi will enter mass production next year, but we anticipate that some companies will commit to Uber’s new platform well before then.

Tesla recalls Powerwall 2 units in Australia

Tesla will recall Powerwall 2 units in Australia after a handful of property owners reported fires that caused “minor property damage.” The fires were attributed to cells used by Tesla in the Powerwall 2.

Tesla Powerwall is a battery storage unit that retains energy from solar panels and is used by homeowners and businesses to maintain power in the event of an outage. It also helps alleviate the need to rely on the grid, which can help stabilize power locally.

Powerwall owners can also enroll in the Virtual Power Plant (VPP) program, which allows them to sell energy back to the grid, helping to reduce energy bills. Tesla revealed last year that over 100,000 Powerwalls were participating in the program.

The Australia Competition and Consumer Commission said in a filing that it received several reports from owners of fires that led to minor damage. The Australian government agency did not disclose the number of units impacted by the recall.

The issue is related to the cells, which Tesla sources from a third-party company.

Anyone whose Powerwall 2 unit is impacted by the recall will be notified through the Tesla app, the company said.

Tesla launches Cybertruck orders in a new market with a catch

Tesla is launching Cybertruck orders in a new market, but there’s a bit of a catch.

The Cybertruck was launched in the Middle East earlier this year, as Tesla launched the ability to place a reservation for the all-electric pickup in the United Arab Emirates. It would be the first market outside of North America that would have the ability to place an order for the Cybertruck.

Other markets where the vehicle has been widely requested, like Europe and Asia, have still not approved the vehicle to be sold to the public, mostly because of size and design restrictions.

However, in the UAE, Tesla is opening up the ability for those who placed reservations for the vehicle to finally put in their order. The Order Configurator is only available to those who have already placed a reservation; it is not yet available to the public.

Tesla said it would open up the public online configurator across the Middle East in the coming weeks:

The UAE is not the only country that will have access to the Cybertruck, as fans in other Middle Eastern countries will also be able to place orders soon. Tesla announced back in April that Saudi Arabia and Qatar would also have Cybertruck deliveries.

These vehicles will be built at Tesla’s Gigafactory Texas plant just outside of Austin, as Gigafactory Berlin and Gigafactory Shanghai, two factories located in the same hemisphere as the Middle East, do not have established lines for Cybertruck production.

As for the other markets, Tesla CEO Elon Musk has hinted that the company could develop a smaller Cybertruck for those markets, as he admitted that in the long term, it likely made sense to build a more compact version for regions where roads are traditionally tighter.

There has been no evidence of Tesla developing this more compact version, but it could eventually happen.
