SpaceX Starship prototype returns to factory after simulated Raptor testing

Published

A SpaceX Starship prototype that could become the first to launch into space has returned to the company’s Starbase rocket factory after completing a series of thorough proof tests.

Starship S24’s test campaign got off to a rough start when the roughly nine-meter (30 ft) wide, 50-meter (~165 ft) tall rocket blew a high-pressure pipe during its very first test – a generally benign ‘pneumatic proof.’ While it appears that most of the ship passed the test, the burst pipe damaged a section of the heat shield and took several days of continuous work to repair and replace. With that hiccup behind it, however, Ship 24 appears to have performed excellently during the next two phases.

On June 1st, the ship fully passed pneumatic proof testing on the second try. On June 2nd, it completed its first cryogenic proof test, referring to the process of filling and pressurizing Starship’s tanks with liquid nitrogen – ultra-cold like its methane and oxygen propellant but without the risk of fire or explosion. Once the basics were out of the way, Ship 24 was cleared for installation on one of two of SpaceX’s suborbital Starship test and launch pads. Over the course of about two months, Pad A was significantly modified both to support Ship 24’s upgraded design and to put it to the test by using giant hydraulic rams to simulate the thrust of Raptor engines.

Ship 24 was installed on the modified mount on June 4th, just 12 hours after completing its first cryoproof. On June 6th and 7th, SpaceX then put the prototype through another pair of cryogenic proof tests, both of which appeared to be completed without issue on the first try. The first test even saw Ship 24 use its nose vents, suggesting that SpaceX may have filled and pressurized both its main tanks and a smaller pair of landing propellant or ‘header’ tanks.

At some point during either or both of the Pad A cryoproofs, it’s believed that the mount’s hydraulic rams were used to test Ship 24’s upgraded aft end by simulating the thrust of six Raptor engines. Like Ship 20, Ship 24 will eventually be outfitted with three smaller sea level-optimized Raptors and three larger vacuum-optimized Raptors. However, Ship 24 will be the first Starship to use new Raptor 2 engines, which are capable of generating almost 25% more thrust. At full throttle, Ship 24 could theoretically produce almost 1400 tons (~3.1M lbf) of thrust at sea level, just shy of twice the thrust of an entire Falcon 9 booster. Starship will be the most powerful orbital spacecraft in history.

First, though, the rocket needs engines. After completing all three cryoproof tests without apparent issue, SpaceX removed Ship 24 from Pad A and transported it back to the Starbase factory on June 9th. While it’s not actually clear if those tests were fully successful, the general assumption is that SpaceX returned the prototype to the factory to fill gaps in its heat shield; complete its aerocovers and raceway; and, most importantly, install six Raptor 2 engines.

If that is the case, Ship 24’s second trip to the launch site could be for wet dress rehearsal and static fire testing – a campaign that could ultimately qualify the ship for Starship’s first orbital launch attempt.

Lucid denies rumors of bankruptcy after over 40% stock drop

Electric vehicle maker Lucid Group has denied rumors of an imminent bankruptcy after a report from this morning sent the stock on a dramatic drop on Wall Street, seeing losses of more than 40 percent during trading hours.

Lucid’s Director of Communications, Nick Twork, responded to the report from Eletric-Vehicles.com, which stated the company’s restructuring advisor, AlixPartners, was asked to review two decisions: taking Lucid shares private or filing for Chapter 11 bankruptcy protection.

The report also claims AlixPartners told the Lucid board to “concentrate on Gravity production while improving its quality, and to temporarily hold back the Lucid Air, the sedan that has defined the company since its launch.”

Twork said:

Shares rebounded after the response to the report, halving its losses as the trading day neared 3 p.m. Eastern.

Lucid has struggled to get its sales off the ground and into more respectable numbers, but the company is in its early years, when things are hard to begin with. It is also backed by several notable investors, including the Saudi Public Investment Fund (PIF), which has nearly limitless money and likely would not ditch an investment of this size so soon.

Lucid shares were down just 14 percent at the time of publication, a far cry from the 55 percent its losses topped out at during the day.

Tesla owner attempts resale of Model S Signature Edition for over $260k

A Tesla owner who purchased a Model S Signature Edition, one of the final 250 units of the all-electric flagship vehicle that the company discontinued earlier this year, is attempting to sell the car despite a no-resale clause that prohibits reselling for the first year.

The car is being sold by J&S Autohaus in Ewing, New Jersey, and is priced at $260,490, well above the $159,420 that Tesla sold it for earlier this year.

To those who do not know, the Model S Signature was a highly exclusive, limited-run farewell variant of the Model S Plaid that was produced this year to mark the end of production of both the Model S and Model X, Tesla’s two flagship vehicles.

Limited to just 250 units with invite-only sales, it serves as a collector’s item celebrating the legacy of the Model S, which helped pioneer Tesla’s electric vehicle success since its 2012 launch.

It bundles top-tier performance with bespoke cosmetic and luxury upgrades, plus Tesla’s Luxe Package. Here’s what the Model S Signature has over the typical Model S Plaid:

  • Exclusive Exterior – Unique Garnet Red Paint, matching door handles, gold Tesla “T” badges upfront, gold Plaid and Signature badging at the rear.
  • Premium Interior – White Alcantara upholstery with gold piping/accents, gold Plaid seat badges, Signature-marked door sills, individually numbered dashboard plaque, gold puddle lights, special interior lighting sequence, and a custom Signature key fob.
  • Performance Upgrades – Carbon-ceramic brakes with gold calipers
  • Bundled Luxe Package – Full Self-Driving (Supervised), four years of Premium Connectivity, free lifetime Supercharging
  • Performance Metrics – ~1,020 horsepower, sub-2-second 0-60 MPH, ~390-mile range

Tesla quickly introduced a No Resale Agreement for the Signature Editions of the Model S and Model X, which would penalize the seller for “the amount of $50,000 or the value received as consideration for the sale or transfer, whichever is greater.”

The company continues:

“If you sell or otherwise transfer the ownership of your Model S or Model X, the remainder of the Recommended Maintenance, Wheel and Tire Protection Plan, and Windshield Protection Plan will transfer automatically to the buyer. The Full Self-Driving (Supervised), Free Supercharging and Premium Connectivity will not transfer with the vehicle and will terminate once the ownership of the Model S or Model X is transferred.”

Tesla will likely come after the seller, especially as it has been about two months since Tesla launched deliveries.

Tesla Full Self-Driving v14.3.5 Early Impressions: new features and early performance

Tesla rolled out Full Self-Driving (Supervised) v14.3.5 yesterday, and about fifty miles of driving on the new version has given me enough time to highlight what seems to be strong about the release and what is not.

Additionally, Tesla has added a few new features with this specific update, which we’ll highlight as well.

Tesla Full Self-Driving v14.3.5 Performance

The new update is business as usual. Things seem to be running completely normal and necessary, but there are a few things that we’ve seemed to pick up on based on our own experience with v14.3.5, as well as what other users are seeing.

Initially, it seems to be more aware of its surroundings, making moves that are incredibly courteous to other drives and operating just a tad more reserved than what the suite might have done previously.

We had two instances where it showed this, the first being FSD needing to pass a Flagger Force vehicle that was placing down signage for the day. Their work truck was right at the front corner of a right-hand turn; typically where most cars travel when they take that turn.

FSD v14.3.5 recognized this, slowed down, and took the turn wide with no issues:

Additionally, v14.3.5 backed up for a semi truck that was making a wide turn onto a road my car was on. This is not new, but it seemed to be backing up for courtesy; it didn’t seem completely necessary, but it might have put some peace of mind in the truck driver’s head:

X user Mike P, also a Pennsylvania native like myself, shared three clips of his Tesla running v14.3.5 performing similar maneuvers. He said:

“FSD turns right into a small alley that only fits one car at a time, sees oncoming car, reverses out of alley to make space, realizes oncoming car is actually parking, re-enters alley.”
Check it out here:

It seems like Speed Profiles are still in need of some tweaking; I am adjusting what Speed Profile I’m in frequently, constantly changing it to get it to travel at the correct speed. This was an issue for me on v14.3.4. It seems like they’re just a little inconsistent.

Terrible Parking

Parking attempts on v14.3.5 were not good. There are quite a few people who have said this:

David Moss, the Tesla owner who has taken multiple coast-to-coast drives without any interventions, also has had some issues with parking early on with v14.3.5:

New Features

Tesla has added the ability to open Camera Preview at any time. Previously, it was only available in Park. Here’s what that feature looks like in action:

Check back later this week for a longer review of what we’ve noticed on Full Self-Driving v14.3.5.
