SpaceX fires up Starship booster at orbital launch pad

SpaceX has fired up a Super Heavy booster for the second time ever.

Published

on

For the first time, SpaceX has static fired a Starship booster at its South Texas orbital launch pad, marking important milestones for both.

After months of cautious testing and multiple rounds of repairs, Super Heavy Booster 7 made it through its first Raptor tests (without causing an explosion) on August 8th, completing a pair of “spin-prime” tests with one Raptor engine. Booster 7 began testing in early April, more than four months ago. As previously discussed on Teslarati, the massive 69-meter-tall (~227 ft) rocket has had an exceptionally rocky journey to its current test campaign.

“Booster 7 first headed to the pad on March 31st and successfully completed two major cryogenic proof tests, but was severely damaged during a subsequent structural stress test. After a few weeks of repairs back at the factory, B7 rolled out to the pad a second time, completed a third cryoproof test, and returned to the factory again on May 14th, where it stayed until June 23rd.”

After several halting, minimal tests in late June and early July, Booster 7 – partially loaded with either propellant or a combination of more neutral cryogenic fluids – attempted a spin-prime test with all 33 of its Raptor 2 engines on July 11th. The mixture of gas that testing created found an unintended ignition source and violently exploded, significantly damaging parts of Super Heavy’s aft section. For the third time, SpaceX returned Booster 7 to its Starbase factory and spent another three weeks removing the rocket’s just-installed Raptor engines and repairing the damage.

On August 6th, Booster 7 rolled to the pad for the fourth time, revealing that SpaceX had only reinstalled 20 of the rocket’s maximum 33 Raptor engines. On August 8th, clearly indicative of a much more cautious second attempt at engine testing, SpaceX ‘primed’ just one of those 20 Raptors by flowing high-pressure gas through the engine to spin up its turbopumps without igniting its preburners (used to generate the gas that powers the turbopumps) or main combustion chamber.

Less than 24 hours later, SpaceX successfully kicked off another round of testing and ignited the same spin-primed engine on the first try. Super Heavy B7 survived the test without visible issue and was safely depressurized and detanked soon after. The lone Raptor engine also appeared to perform perfectly and shut down cleanly after a stable three or four-second burn.

Booster 7’s first static fire – also the second static fire test of a Super Heavy – was the first test of an upgraded Raptor 2 engine on any rocket prototype. At the cost of slightly less efficient combustion, Raptor 2 is designed to produce up to 230 tons (~510,000 lbf) of thrust – almost 25% more than Raptor 1 (185 tons or ~410,000 lbf).

With about four hours left in August 9th’s test window, which closes at 10 pm CDT (03:00 UTC), SpaceX still has time to test Starship S24, which also completed Raptor spin-prime tests on August 8th. SpaceX has an additional 10am-10pm road closure scheduled on Wednesday, August 10th.

Investor's Corner

Lucid denies rumors of bankruptcy after over 40% stock drop

Published

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

Published

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.
