SpaceX sends Starship prototype to launch pad after engine installation

Published

on

After several weeks of work back at SpaceX’s Starbase rocket factory, the company has transported a new and improved Starship prototype to nearby test and launch facilities, where it joined a similarly upgraded Super Heavy booster.

That Starship prototype – Ship 24 or S24 – is closely following in the footsteps of Super Heavy Booster 7 (B7), which kicked off a similar phase of preflight testing about two weeks ago. The purposes of their latest trips from the factory to the launch pad are also largely the same and could potentially open the door for Starship’s inaugural orbital launch attempt sometime later this year if the process goes smoothly. Both protypes have a ways to go, however.

Booster 7 and Ship 24 got off to fairly rocky starts when they began a less risky phase of proof testing in May and June. Apparently caused by improper sequencing or a small design flaw, a large steel tube meant to carry liquid methane fuel through Booster 7’s liquid oxygen tank and double as a storage vessel for landing propellant violently imploded when a vacuum formed inside it. It took SpaceX several weeks to repair the damage but, defying the odds, the tube was eventually repaired and Booster 7 completed another two proof tests soon after.

A few weeks later, during one of Ship 24’s first tests, a much smaller internal pipe – likely carrying high-pressure gas – also failed, damaging heat shield tiles and other adjacent plumbing. S24’s troubles were less dramatic and only took a few days to fix, but both were still new failure modes for the Starship program and served as a reminder that Starship hardware remains relatively immature and that SpaceX is still learning. Nonetheless, they also demonstrated SpaceX’s ability to respond quickly to new problems, as both B7 and S24 sailed through additional testing without apparent issue after quick repairs.

After completing cryogenic proof and thrust simulation testing, B7 and S24 returned to SpaceX’s factory facilities for Raptor installation and finishing touches. SpaceX took about six weeks to install 33 Raptor engines and associated heat shielding on Booster 7, while installing six Raptors and wrapping up a few other aspects of Ship 24 took about four weeks.

Aside from the installation of most of the Starship’s missing heat shield tiles, Ship 24’s preparations did include one particularly unique step involving its payload bay prototype. SpaceX’s first stab at a Starship payload bay has been likened to a giant Pez dispenser, which is not entirely inaccurate. Exclusive to Starlink, satellites will be stored on a rectangular rack that’s assumed to operate like an elevator. As an unknown mechanism pushes two satellites at a time through Starship’s slot-like bay door, the stack of satellites will feed downwards like bullets in a magazine until the full set is fully deployed.

In late June, SpaceX attached a giant white box to a crane and positioned the box to interface with Ship 24’s bay door, where it hung for the better part of a day. The test confirmed speculation that the box was meant to solve perhaps the most obvious problem SpaceX’s unique payload bay design posed: payload installation. SpaceX’s solution appears to involve using the deployment mechanism in reverse, with the white box conveying Starlink Gen2 satellites through the ‘slot’ and the dispenser grabbing and lifting each pair up into the bay.

It’s possible that Ship 24 will have a handful of Starlink V2/Gen2 satellites loaded into its bay if it passes its next tests. Before being cleared for flight, Ship 24 will need to complete at least one nominal wet dress rehearsal (simulating every aspect of a launch short of engine ignition) and one six-engine static fire, though several tests are far more likely. Starship S24’s test campaign will benefit significantly from Starship S20, which survived extensive testing (and multiple six-Raptor static fires) in 2021. In comparison, Super Heavy B7’s similar wet dress rehearsal and static fire test campaign will be almost entirely new to SpaceX, save for a single three-engine static fire completed by an outdated booster prototype last year.

SpaceX could attempt to static fire Booster 7 for the first time as early as Wednesday, July 6th. It’s unclear if the company will attempt to kick off Ship 24’s next round of testing in the gaps between Super Heavy B7’s static fire testing. While unlikely, SpaceX is technically capable of testing Ship 24 and Booster 7 simultaneously.

GM takes latest step to avoid disaster as EV efforts get derailed

There was an even larger step taken this morning, as the Detroit Free Press reported that GM was idling its Factory Zero plant in Michigan until late November, placing about 1,200 workers on indefinite layoff status.

General Motors has taken its latest step to avoid financial disaster as its electric vehicle efforts have been widely derailed.

GM’s electric vehicle manufacturing efforts started off hot, and CEO Mary Barra seemed to have a real hold on how the industry and consumers were starting to evolve toward sustainable powertrains. Even former President Joe Biden commended her as being a major force in the global transition to EVs.

However, the company’s plans have not gone as they’ve drawn them up. GM has reported some underwhelming delivery figures in recent quarters, and with the loss of the $7,500 tax credit, the company is planning for what is likely a substantial setback in its entire EV division.

Earlier this month, the company reported it would include a $1.6 billion charge in its quarterly earnings results from EV investments. It was the first true sign that things with GM’s EV projects were going to slow down.

There was an even larger step taken this morning, as the Detroit Free Press reported that GM was idling its Factory Zero plant in Michigan until late November, placing about 1,200 workers on indefinite layoff status.

This is in addition to the 280 employees it has already laid off after production cuts that happened earlier this year at the Detroit-Hamtramck plant.

After November 24, GM will bring back 3,200 people to work until January 5 to operate both shifts. On January 5, GM is expected to keep 1,200 workers on indefinite layoff.

GM is not the only legacy automaker to make a move like this, as Ford has also started to make a move that reflects a cautious tone regarding how far and how committed it can be to its EV efforts.

After the tax credit was lost, it seemed to be a game of who would be able to float their efforts longest without the government’s help. Tesla CEO Elon Musk long said that the loss of these subsidies would help the company and hurt its competitors, and so far, that is what we are seeing.

Elon Musk was right all along about Tesla’s rivals and EV subsidies

However, Tesla still has some things to figure out, including how its delivery numbers will be without the tax credit. Its best quarter came in Q3 as the credit was expiring, but Tesla did roll out some more affordable models after the turn of the quarter.

Tesla expands Robotaxi geofence, but not the garage

This has broadened its geofence to nearly three times the size of Waymo’s current service area, which is great from a comparative standpoint. However, there seems to be something that also needs to be expanded as the geofence gets larger: the size of the Robotaxi fleet.

Tesla has expanded its Robotaxi geofence four times, once as recently as this week.

However, the company has seemingly kept its fleet size relatively small compared to the size of the service area, making some people — even pro-Tesla influencers — ask for more transparency and an expansion of the number of vehicles it has operating.

Over the past four months, Tesla has done an excellent job of maintaining growth with its service area in Austin as it continues to roll out the early stages of what is the Robotaxi platform.

The most recent expansion brought its size from 170 square miles (440.298 sq. km) to 243 square miles (629.367 sq. km).

Tesla sends clear message to Waymo with latest Austin Robotaxi move

This has broadened its geofence to nearly three times the size of Waymo’s current service area, which is great from a comparative standpoint. However, there seems to be something that also needs to be expanded as the geofence gets larger: the size of the Robotaxi fleet.

Tesla has never revealed exactly how many Model Y vehicles it is using in Austin for its partially driverless ride-hailing service (We say partial because the Safety Monitor moves to the driver’s seat for freeway routes).

When it first launched Robotaxi, Tesla said it would be a small fleet size, between 10 and 20 vehicles. In late August, after its second expansion of the service area, it then said it “also increased the number of cars available by 50 percent.”

The problem is, nobody knows how many cars were in the fleet to begin with, so there’s no real concrete figure on how many Robotaxis were available.

This has caused some frustration for users, who have talked about the inability to get rides smoothly. As the geofence has gotten larger, there has only been one mentioned increase in the fleet.

Tesla did not reveal any new figures or expansion plans in terms of fleet size in the recent Q3 Earnings Call, but there is still a true frustration among many because the company will not reveal an exact figure.

Tesla recalls 6,197 Cybertrucks for light bar adhesive issue

On October 20, Tesla issued a voluntary recall of the impacted vehicles and has identified 619 warranty claims and just a single field report that is related to the issue.

Tesla has recalled 6,197 Cybertrucks for a light bar adhesive issue that was utilized by Service to install the aftermarket part.

According to the National Highway Traffic Safety Administration (NHTSA), impacted vehicles may have had the light bar “inadvertently attached to the windshield using the incorrect surface primer.”

Tesla identified an issue with the light bar’s adhesion to glass back in February and worked for months to find a solution. In October, the company performed chemical testing as a part of an engineering study and determined the root cause as the BetaPrime primer it utilized, figuring out that it was not the right surface priming material to use for this specific application.

On October 20, Tesla issued a voluntary recall of the impacted vehicles and has identified 619 warranty claims and just a single field report that is related to the issue.

The component is manufactured by a Romanian company called Hella Romania S.R.L., but the issue is not the primer’s quality. Instead, it is simply the fact that it is not the correct adhesive for this specific type of application.

Tesla says there are no reports of injuries or deaths due to this issue, and it will be resolved. In the 473 report that the NHTSA released this morning, Tesla said:

“At no charge to customers, Tesla will inspect the service-installed optional off-road light bar accessory for delamination or damage and if either is present, replace the light bar with a new light bar adhered with tape and a positive mechanical attachment. If no delamination or damage is present, Tesla will retrofit the service-installed optional off-road light bar accessory with a positive mechanical attachment.”

This is the third recall applied to Cybertrucks this year, as one on March 18 highlighted the potential for exterior trim panels to detach while driving, and another earlier this month when the NHTSA said its front parking lights were too bright.

Tesla resolved the first with a free assembly replacement, while the headlight issue was fixed with an Over-the-Air software update earlier this week. Owners said there was a noticeable difference in the brightness of the lights now compared to previously.
