For the second time, SpaceX is gearing up to install a full six Raptor engines on the first orbital-class Starship prototype.

This time around, though, there’s reason to believe that the preparations SpaceX is making aren’t a false start and could culminate in one or several record-breaking Starship static fires as early as next week.

SpaceX installed Raptors on Starship S20 for the first time in early August, outfitting the 50m (165 ft) tall prototype with a full six engines as part of a fit test that ultimately saw it installed on top of a Super Heavy booster. Ship 20 only spent an hour on top of Booster 4, though, and was quickly returned to Starbase build site for Raptor removal and final outfitting. Ship 20 was then rolled back to the launch site and installed on one of two suborbital launch mounts and test stands in mid-August, where it has sat ever since.

Between September 4th and 10th, SpaceX then appeared to install three sea-level-optimized Raptor Center (RC) engines and one Raptor Vacuum (RVac) engine on Starship S20 before the prototype had completed any proof testing. Whether that set of installs was a fit test or an aborted attempt at full installation, SpaceX seemingly paused at three or four Raptors and ultimately removed the lone RVac and one or more of S20’s sea-level engines. Another sea-level Raptor was (re)installed on September 15th.

After a frenetic month of back and forth with no obvious rhyme or reason, all of Ship 20’s Raptors were removed and a series of hydraulic rams used to simulate engine thrust – removed, unused, back in August – were reinstalled. Starship then completed pneumatic and cryogenic proof tests in the last few days of September.

After another ten or so days of unusual downtime, SpaceX began reinstalling Raptors on Ship 20 – one sea-level and one vacuum – around October 10th for a static fire test campaign that began about a week later. Finally, on October 21st, SpaceX fired up the orbital-class prototype for the first time, also completing the first test of a Raptor Vacuum engine installed on a Starship. Barely an hour later, Starship S20 performed a second test, simultaneously firing up both RVac and RC engine in another first.

Barely a full day after that successful back-to-back static fire test, SpaceX rolled two more sea-level Raptors to the suborbital pad and installed them on Ship 20. Another unusual week of downtime later and, on October 28th, SpaceX has rolled two more Raptor Vacuum engines from the build site to the launch pad and staged them beside Starship. Once installed, Starship S20 will, for the second time, be fully outfitted with six Raptors. Having already fired up two of those engines without needing either replaced, though, there’s a decent chance that all six will actually be used before Ship 20’s next bout of engine removal/installation deja vu.

SpaceX has never fired more than three engines at a time on a Starship prototype or at its suborbital test site, so a number of firsts potentially lay before Ship 20 as it nears a second round of static fire testing. There is some uncertainty as to whether the suborbital test stands can actually handle the stress from static fires with more than three Raptors, but if they can, then S20 will likely be the first prototype to ignite more 4+ engines and could become the first Starship to fire all six engines at once.

SpaceX currently has one possible test window scheduled from 10am to 6pm CDT on Monday, November 1st, though it could be another week or more before Starship S20’s next static fire attempt if past trends continue.

Tesla states Giga Berlin workforce is stable, rejects media report

As per the electric vehicle maker, production and employment levels at the facility remain stable.

Tesla Germany has denied recent reports alleging that it has significantly reduced staffing at Gigafactory Berlin. As per the electric vehicle maker, production and employment levels at the facility remain stable.

Tesla denies Giga Berlin job cuts report

On Wednesday, German publication Handelsblatt reported that Tesla’s workforce in Gigafactory Berlin had been reduced by about 1,700 since 2024, a 14% drop. The publication cited internal documents as its source for its report. 

In a statement to Reuters, Tesla Germany stated that there has been no significant reduction in permanent staff at its Gigafactory in Grünheide compared with 2024, and that there are no plans to curb production or cut jobs at the facility. 

“Compared to 2024, there has been no significant reduction in the number of permanent staff. Nor are there any such plans. Compared to 2024, there has been no significant reduction in the number of permanent staff. Nor are there any such plans,” Tesla noted in an emailed statement. 

Tesla Germany also noted that it’s “completely normal” for a facility like Giga Berlin to see fluctuations in its headcount.

A likely explanation

There might be a pretty good reason why Giga Berlin reduced its headcount in 2024. As highlighted by industry watcher Alex Voigt, in April of that year, Elon Musk reduced Tesla’s global workforce by more than 10% as part of an effort to lower costs and improve productivity. At the time, several notable executives departed the company, and the Supercharger team was culled.

As with Tesla’s other factories worldwide, Giga Berlin adjusted staffing during that period as well. This could suggest that a substantial number of the 1,700 employees reported by Handelsblatt were likely part of the workers who were let go by Elon Musk during Tesla’s last major workforce reduction.

In contrast to claims of contraction, Tesla has repeatedly signaled plans to expand production capacity in Germany. Giga Berlin factory manager André Thierig has stated on several occasions that the site is expected to increase output in 2026, reinforcing the idea that the facility’s long-term trajectory remains growth-oriented.

Elon Musk gets brash response from Ryanair CEO, who thanks him for booking increase

Published

ARLINGTON, Va., May 9, 2023 – Boeing [NYSE: BA] and Ryanair announced Europe’s leading low-cost airline has selected the largest 737 MAX model to power its future growth with an order for up to 300 airplanes. The purchase agreement is the biggest in Ryanair’s history and includes a firm order for 150 737-10 jets and options for 150 more. Image credit: Boeing

Elon Musk got a brash response from Ryanair CEO Michael O’Leary, who said in a press conference on Wednesday afternoon that the Tesla frontman’s criticism of the airline not equipping Starlink has increased bookings for the next few months.

The two have had a continuing feud over the past several weeks after Musk criticized the airline for not using Starlink for its flights, which would enable fast, free, and reliable Wi-Fi on its aircraft.

Tesla CEO Elon Musk trolls budget airline after it refuses Starlink on its planes

Musk said earlier this week that he was entertaining the idea of purchasing Ryanair and putting someone named Ryan in charge, which would oust O’Leary from his position.

However, the barbs continued today, as O’Leary held a press conference, aiming to dispel any beliefs about Starlink and its use case for Ryanair flights, which are typically short in length.

O’Leary said in the press conference today:

“The Starlink people believe that 90% of our passengers would happily pay for wifi access. Our experience tells us less than 10% would pay; He (Elon) called me a retar*ed twat. He would have to join the back of a very, very long queue of people that already think I’m a retar*ed twat, including my four teenage children.”

He then went on to say that, due to Musk’s publicity, bookings for Ryanair flights have increased over the past few days, up 2 to 3 percent:

“But we do want to thank him for the wonderful boost in publicity. Our bookings are up 2-3% in the last few days. So thank you to Mr. Musk, but he’s wrong on the fuel drag. Non-European citizens cannot own a majority of European airlines, but if he wants to invest in Ryanair, we think it would be a very good investment.”

O’Leary didn’t end there, as he called Musk’s social media platform X a “cesspit,” and said he has no concern over becoming a member of it. However, Ryanair has been very active on X for several years, gaining notoriety for being comical and lighthearted.

The public spat between the two has definitely benefited Ryanair, and many are calling for it to end, especially those who support Musk, as they see it as a distraction.

Nevertheless, it is likely going to end with no real movement either way, and is more than likely just a bit of hilarity between the two parties that will end in the coming days.

Tesla CEO Elon Musk outlines expectations for Cybercab production

“…initial production is always very slow and follows an S-curve. The speed of production ramp is inversely proportionate to how many new parts and steps there are. For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow, but eventually end up being insanely fast.”

Tesla CEO Elon Musk outlined expectations for Cybercab production as the vehicle is officially set to start rolling off manufacturing lines at the company’s Giga Texas factory in less than 100 days.

Cybercab is specifically designed and catered to Tesla’s self-driving platform and Robotaxi ride-hailing service. The company has been pushing hard to meet its self-set expectations for rolling out an effective self-driving suite, and with the Cybercab coming in under 100 days, it now needs to push for Unsupervised Self-Driving in the same time frame.

Tesla CEO Elon Musk confirms Robotaxi is set to go unsupervised

This is especially pertinent because the Cybercab is expected to be built without a steering wheel or pedals, and although some executives have said they would build the car with those things if it were necessary.

However, Musk has maintained that the Cybercab will not have either of those things: it will have two seats and a screen, and that’s it.

With production scheduled for less than 100 days, Musk broke down what people should expect from the initial manufacturing phases, being cautiously optimistic about what the early stages will likely entail:

“…initial production is always very slow and follows an S-curve. The speed of production ramp is inversely proportionate to how many new parts and steps there are. For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow, but eventually end up being insanely fast.”

Musk knows better than most about the challenges of ramping up production of vehicles. With the Model 3, Musk routinely refers to it as “production hell.” The Cybertruck, because of its polarizing design and stainless steel exterior, also presented challenges to Tesla.

The Cybercab definitely presents an easier production process for Tesla, and the company plans to build millions of units per year.

Musk said back in October 2024:

“We’re aiming for at least 2 million units a year of Cybercab. That will be in more than one factory, but I think it’s at least 2 million units a year, maybe 4 million ultimately.”

When April comes, we will find out exactly how things will move forward with Cybercab production.
