In 15 hours, SpaceX has rolled a new Starship to its South Texas launch and test facilities, reassembled the world’s largest rocket, launched Starlink satellites to orbit, and recovered a reused Falcon 9 booster in port.

The burst of activity began around sunset at SpaceX’s Starbase rocket factory in Boca Chica, Texas when a new orbital-class Starship prototype left its ‘nest’ for the first time. SpaceX rolled the Starship – known as Ship 25 – a few miles down the highway to its nearby launch and test facilities, where workers connected it to a large crane and waited for daylight.

Around 9 am CDT the following day, October 20th, SpaceX lifted Ship 25 onto one of two Starship test stands, where it will eventually attempt to complete several qualification tests. While Ship 25 was still suspended in mid-air, the Starbase launch pad’s orbital launch tower began lifting a different prototype, Ship 24, into the air with a pair of giant ‘chopsticks’ – mechanical arms designed by SpaceX to replace one of the largest mobile cranes in the world.

Then, while it was stacking Ship 24 on top of Super Heavy Booster 7 and installing Ship 25 on a test stand, a Falcon 9 rocket carrying 54 new Starlink satellites lifted off from Cape Canaveral, Florida. Minutes prior, SpaceX finished craning a reused Falcon 9 booster off one of its drone ship landing platforms in a port ten miles south.

Starlink 4-36 was SpaceX’s 48th launch of 2022 and 56th launch in less than 12 months, so its Falcon launch program simply doesn’t have time to waste. Drone ship Just Read The Instructions (JRTI) returned to port with Falcon 9 booster B1069 about 12 hours before the rocket was transferred from the ship’s deck to a stand on SpaceX’s Port Canaveral dock space. The company will now be able to retract B1069’s legs and complete any necessary booster and drone ship refurbishment, ensuring that both will be ready for their next missions in the near future.

Back in Texas, SpaceX is scheduled to begin thoroughly testing a fully-stacked Starship rocket for the first time as early as Monday, October 24th. Ship 24 was reinstalled on Booster 7 for that purpose after SpaceX disassembled the pair for several days, possibly due to forecasts of high winds. The test campaign is expected to begin with the first full wet dress rehearsal (WDR) of a two-stage Starship, meaning that the rocket will be fully loaded with thousands of tons of liquid methane and oxygen propellant and run through a simulated launch countdown that ends just before engine ignition.

If successful, SpaceX will likely restart Booster 7 static fire testing and continue to work its way up to the first simultaneous ignition of all 33 of its Raptor 2 engines. If the pair survive WDR and static fire testing, SpaceX could begin preparing the same rocket for Starship’s orbital launch debut.

If significant issues arise during testing, SpaceX could choose to retire Ship 24 and/or Booster 7 and move on to a new and improved pair: likely Ship 25 and Booster 8 or 9. Already complete, Super Heavy Booster 8 has been sitting untouched at Starbase’s launch site for weeks, making it uncertain whether SpaceX actually intends to test or use the prototype. Booster 9 is just one stack away from completion, at which point it will be ready to begin proof testing. According to CEO Elon Musk, B9 features significant improvements that will make it more resilient to mid-flight Raptor engine failures. It could also be the first Super Heavy booster with no hydraulic system, thanks to a new version of Raptor that replaces hydraulic thrust vectoring with a battery-powered alternative.

Starship S25 could kick off its own proof testing as early as next week. Unlike Ship 24, Ship 25 went straight from the factory to a test stand that has been modified with six hydraulic rams. Those rams will simulate the thrust of six Raptor 2 engines (up to ~1400 tons or 3.1M lbf) while the Starship is simultaneously loaded with cryogenic liquid oxygen and/or nitrogen, combining peak mechanical and thermal stresses into one test. Once Ship 25 is done, it will be rolled back to the factory for Raptor engine installation and will eventually return to the pad for static fire testing.

Tesla Robotaxi gets shade thrown on it by ex-Waymo CEO

“If they were striving to re-create today’s Bay Area Uber experience, looks like they’ve absolutely nailed it.”

Tesla Robotaxi is getting more shade thrown on it by skeptics from all corners of the industry. Recently, it received some criticism from ex-Waymo CEO John Krafcik, who led the currently sits on the board of Tesla rival Rivian.

Robotaxi is Tesla’s self-driving ride-hailing service that operates in both Austin, Texas, and the San Francisco Bay Area.

In Austin, it launched on June 22, and it was the first city where Tesla launched driverless rides to a select group of invited guests. That group, as well as the geofence in Austin, has expanded several times in the roughly two months since its launch.

In the Bay, Tesla is not legally allowed to call the platform “Robotaxi,” so it refers to it as its ride-hailing service. This was confirmed by CEO Elon Musk.

However, Krafcik, who was with Waymo for about seven years, is skeptical of the Robotaxi fleet, basically calling it less than impressive and stating that it is a lot like Uber in San Francisco.

In an interview with Business Insider, Krafcik revealed his true thoughts about Tesla’s efforts:

“If they were striving to re-create today’s Bay Area Uber experience, looks like they’ve absolutely nailed it.”

He went on to say that the company’s decision to keep Safety Monitors in the vehicle for the time being makes the vehicle not a Robotaxi. In Austin, there is not a Safety Monitor in the driver’s seat, only in the front passenger’s seat.

In the Bay Area, there is a Safety Monitor in the driver’s seat, which is a regulatory requirement with the platform currently.

Krafcik continued:

“Please let me know when Tesla launches a robotaxi — I’m still waiting. It’s (rather obviously) not a robotaxi if there’s an employee inside the car.”

The presence of a Safety Monitor is only a measure of precaution currently, and Tesla has said that it is purely a move to ensure riders are kept out of danger.

Musk said recently that Tesla is being “paranoid” over safety, and for good reason. Any instance of an accident could set Tesla, or any self-driving program for that matter, back years.

Unfortunately, Krafcik said he has no desire to try Robotaxi, so it won’t get a fair shot at changing his mind.

An early reviewer of the Tesla Model Y L in China has teased what could very well be the most comprehensive list of features that has been shared so far about the upcoming extended wheelbase crossover.

Based on the early reviewer’s insights, the Model Y L could very well become Tesla’s best-selling family vehicle by a mile.

Model Y L sightings

The Tesla Model Y L has reportedly entered production in Giga Shanghai, though the vehicle itself is not being sold in the company’s domestic website as of yet. That being said, sightings from the electric vehicle community have suggested that Tesla China is now hard at work transporting Model Y L units to select stores across the country.

The Model Y L was listed in the China Ministry of Industry and Information Technology’s (MIIT) latest batch of new energy vehicle models that are eligible for vehicle purchase tax exemptions. Based on the MIIT’s filings, the vehicle will feature a 82.0-kWh lithium-ion battery from LG Energy Solution. It is also expected to add roughly 178 mm (7 inches) to the overall length of the standard Model Y, with 152 mm (6 inches) being dedicated to stretching the wheelbase.

New Model Y L insights 

A China-based blogger who reportedly previewed the Model Y L ahead of an expected nondisclosure agreement lift on Tuesday or Wednesday shared some of the vehicle’s alleged updates. As per the blogger, the Model Y L’s biggest updates focus on comfort and interior features. The front seats have reportedly been reworked with better cushioning, leg rests and lumbar support, though they do not add zero-gravity seating or massage functions.

The vehicle also comes with Continuous Damping Control suspension, a larger central display and an upgraded audio system with about 18 speakers, which was described as a significant improvement in sound quality. Amenities have reportedly been expanded for passengers in all three rows. Heating and ventilation will reportedly be available in the first and second rows, while the third row will have heating only. 

The third-row space was described as adequate, with a passenger standing 1.78 meters tall reportedly being able to sit with a fist’s worth of headroom. Tesla’s minimalist interior design reportedly remains, but the second row now includes armrests. Both the second and third rows also reportedly fold flat to form a large bed, though not as flat as the standard Model Y. A voice wake-up feature, “Hi Tesla,” is also included for China models.

The Federal Aviation Administration has closed its review of SpaceX’s Starship Flight 9 mishap, clearing the way for the next launch attempt as soon as August 24. 

Flight 9 ended with the loss of both the Super Heavy booster and the upper stage, but regulators accepted SpaceX’s findings that a fuel component failure was the root cause. No public safety concerns were reported from the incident.

Starship recovery lessons

SpaceX noted that Flight 9 marked the first reuse of a Super Heavy booster. Unlike prior attempts, the company did not try a tower “chopsticks” recovery, opting instead for an offshore return that ended in a destructive breakup. The upper stage was also lost over the Indian Ocean. 

As per the FAA in its statement, “There are no reports of public injury or damage to public property. The FAA oversaw and accepted the findings of the SpaceX-led investigation. The final mishap report cites the probable root cause for the loss of the Starship vehicle as a failure of a fuel component. SpaceX identified corrective actions to prevent a reoccurrence of the event.”

SpaceX also highlighted that Flight 9’s debris did not harm any wildlife. “SpaceX works with an experienced global response provider to retrieve any debris that may wash up in South Texas and/or Mexico as a result of Starship flight test operations. During the survey of the expected debris field from the booster, there was no evidence of any floating or deceased marine life that would signal booster debris impact harmed animals in the vicinity,” the private space company noted.

Expanding test objectives

To mitigate risks, SpaceX plans to adjust return angles for future flights and conduct additional landing burn tests on Flight 10. SpaceX will attempt a Gulf splashdown for Flight 10 once more, instead of a tower capture, according to a report from the Boston Herald.

The upcoming Starship Flight 10, which will be launching from Starbase in Texas, will also mark SpaceX’s attempt to perform its first payload deployment and an in-space Raptor relight. Despite recent setbacks, which include the last three flights ending with the upper stage experiencing a rapid unscheduled disassembly (RUD), Starship remains central to NASA’s Artemis program, with a variant tapped as the human landing system for Artemis III, the first since the Apollo program. 

Standing more than 400 feet tall and generating 16 million pounds of thrust, Starship remains the most powerful rocket flown, though it has yet to complete an orbital mission. The FAA has expanded SpaceX’s license to allow up to 25 Starship flights annually from Texas.
