SpaceX Starship booster heads to launch pad for the fifth time

Published

on

For the fifth time in five months, SpaceX has transported its most advanced Starship booster prototype from the Starbase factory to the launch pad, setting the stage for another round of testing.

Super Heavy Booster 7 (B7) returned to the factory for the fourth time on August 12th after becoming the first prototype of any kind to perform a static fire engine test while installed on SpaceX’s orbital Starship launch mount. In the days prior, the booster completed two back-to-back static fire tests with one of the 20 Raptor engines installed on the rocket, both of which apparently gave SpaceX enough confidence to prepare for the next phase of testing.

That relatively cautious progress only came after SpaceX attempted to test all 33 of the prototype’s Raptors at once during its first engine test. Whether it was the fault of overzealous managers or executives or a genuine oversight is not clear, but the combined behavior of Super Heavy and the orbital launch pad was not properly characterized before testing began. As a result, the cloud of flammable gas the rocket released during its attempted 33-engine ‘spin-prime’ test found an ignition source and violently exploded on July 11th, causing damage throughout Booster 7’s aft engine section that required several weeks of repairs between July 15th and August 6th.

When the Super Heavy rolled to the pad for the fourth time on August 6th, it was missing all 13 center Raptors, leaving only the outer ring of 20 Raptor Boost engines partially installed for the tests that followed. Thankfully, things went much better on the second try and Booster 7 completed two spin-prime tests with a single Raptor engine, followed by two successful static fire tests on August 9th and 11th. The latter test was the longest Starbase static fire ever (by a factor of ~3) and lasted about 20 seconds, allowing SpaceX to test Booster 7’s autogenous pressurization. That system pressurizes Super Heavy’s tanks by turning small quantities of cryogenic liquid propellant into gas, ensuring that its tanks remain stable as they’re rapidly drained of thousands of tons of propellant.

On August 12th, Booster 7 returned to the factory, where workers installed the rocket’s 13 center engines for the second time. Booster 7 headed back to the orbital launch site (OLS) on August 23rd and the pad’s robotic launch tower used a pair of arms to lift the rocket off its transport stand and place it on the launch mount by the end of the day.

In addition to readying Booster 7 for its next phase of static fire testing, teams of SpaceX workers took advantage of the unplanned lull in testing to modify the orbital launch mount. It’s impossible to know what exactly was done without official confirmation, but it’s likely that SpaceX was attempting to quickly fix the shortcoming(s) that allowed the July 11th explosion to happen. Without a fix, it’s unlikely that SpaceX would want to proceed with plans to ignite large numbers of Raptor engines simultaneously – a series of tests that must be completed before Starship can safely attempt its first orbital launch.

It’s unclear what exactly that fix entails, but it could involve a system to constantly flood the engine section with fire-stopping nitrogen gas or potentially take the shape of a system of vents that will connect to every Raptor engine and remove methane gas before it can turn into flammable clouds.

It’s possible that Booster 7 has returned to the launch pad solely for fit checks or some other basic proof-of-concept testing. It’s also possible that the returns signifies that SpaceX is confident in its quick launch mount fix and ready to restart static fire testing.

As Booster 7 prepares for that next phase of testing, SpaceX may also be ready to restart static fire testing with Starship S24, which paused shortly before Super Heavy returned to the factory. SpaceX appears to be modifying the suborbital launch mount and test stand Ship 24 is installed on, which could explain the lack of ship testing since August 11th. SpaceX has 12-hour test windows tentatively scheduled on August 24th and 25th, either of which could be used to test either or both prototypes.

If all goes to plan, Ship 24 and Booster 7 will eventually complete all the qualification testing SpaceX can throw at them and be ready to support Starship’s first orbital launch attempt sometime before the end of 2022.

Tesla analysts are expecting big things from the stock

Tesla analysts are expecting big things from the stock (NASDAQ: TSLA) after many firms made price target adjustments following the Q3 Earnings Call.

Last Wednesday, Tesla reported earnings with record revenue but missed EPS estimates.

It blew delivery expectations out of the water with its strongest quarter in company history, but Tesla’s future relies on the development of autonomous vehicles, robotics, and AI, which many bullish firms highlight as major strengths.

The earnings call reiterated those points, along with the belief that Tesla CEO Elon Musk should be rewarded with a newly proposed pay package that would enable him to gain $1 trillion in wealth if he comes through on a lengthy list of performance tranches.

Nine Wall Street firms made adjustments to their outlook on Tesla shares in the form of price target increases since last Wednesday’s call, all of which are indications of big expectations for the stock moving forward.

Here are the nine firms that made moves:

  • Truist – $280 to $406, reiterated Hold rating
  • Roth MKM – $395 to $404, reiterated Buy rating
  • Cantor Fitzgerald – $355 to $510, reiterated Overweight rating
  • Deutsche Bank – $435 to $440, reiterated Buy rating
  • Mizhuo – $450 to $485, reiterated Outperform rating
  • New Street Research – $465 to $520, reiterated Buy rating
  • Evercore ISI – $235 to $300, reiterated In Line rating
  • Freedom Capital Markets – $338 to $406, upgraded to Hold rating
  • China Renaissance – $349 to $380, reiterated Hold rating

The boosts in price target are largely due to Tesla’s future projects, as Roth MKM, Cantor Fitzgerald, Mizuho, New Street Research, and Evercore ISI all explicitly mention Tesla’s autonomy, robotics, and AI potential as the main factors for its price target boosts.

Cantor Fitzgerald raises Tesla PT To $510, citing Cybercab, Semi, and AI momentum

It is no surprise that many firms are adjusting their outlook on Tesla shares considerably in an effort to prepare for the company’s transition to even more of a tech company than a car company.

The issue with many analysts is that they treat the company’s vehicle deliveries as the main indicator of value.

However, Tesla has a robust energy division, which was a major contributor to the company’s strong margins and gross profit in Q3, as well as its prowess in robotics and AI.

Additionally, the company is seen as a key player in the autonomy field, especially after launching driverless rides on a Robotaxi platform in Austin and expanding a similar program in the Bay Area.

Tesla shares were up over 5 percent at 12:18 p.m. on the East Coast.

Tesla Board Chair Robyn Denholm has provided a rather compelling update on Optimus’ improving dexterity. As per the executive, the humanoid robot, which is expected to enter initial production next year, is now able to perform more deliberate tasks, such as folding laundry. 

Optimus’ dexterity

During an interview with CNBC, Denholm was asked how close Optimus was to true dexterity. Achieving human-like dexterity is a key goal for Optimus as the robot is designed to be able to perform tasks that are traditionally performed by humans. This means that Optimus should be able to move its hands in a very delicate manner. During the segment, one of CNBC’s hosts mentioned that humanoid robots today are not able to fold laundry just yet. 

Denholm responded that Tesla’s robot is now able to perform the task. “Optimus can fold laundry. I’ve been in the lab with Optimus. He can fold laundry. He can wipe the table really well. He can hand things to you. You can actually shake hands with him. The tactile nature of his hand is actually really very good,” the Tesla Board Chair stated.

Redefining robotics

The executive reiterated that Optimus is already operating in Tesla’s Palo Alto offices today. “We’re redefining what transportation is, but we’re also redefining robotics and what AI brings to robotics and how versatile the robots will be in the future,” Denholm noted.

Elon Musk has reiterated the importance of Optima’s hands during the Q3 2025 earnings call. While discussing the humanoid robot’s capabilities, Musk stated that Optimus, in its production form in the future, should be able to perform incredibly delicate tasks such as surgery. This, the CEO noted, would be pivotal in Tesla’s efforts to push the world towards sustainable abundance.

“Going beyond sustainable energy to say, sustainable abundance is the mission, where we believe with Optimus and self-driving, we can actually create a world where there is no poverty, where everyone has access to the finest medical care. Optimus will be an incredible surgeon, for example. Imagine if everyone had access to an incredible surgeon,” Musk said.

Tesla comes through on huge promise for Bay Area ride-hailing service

Tesla’s ride-hailing service in the California Bay Area is somewhat similar to what the company is doing with Robotaxi in Austin, Texas.

Tesla has come through on a huge promise for its Bay Area ride-hailing service just two months after aiming to expand to a new territory.

Tesla’s ride-hailing service in the California Bay Area is somewhat similar to what the company is doing with Robotaxi in Austin, Texas.

However, regulatory rules and the fact that the company is operating with someone in the driver’s seat —a stark difference from the operation in Austin —have kept the business categorized as a ride-hailing application in California.

But Tesla is still breaking barriers down with its service, which operates entirely using the Full Self-Driving (Supervised) platform, as the “Safety Monitors” are only there to ensure safety and take over in the most necessary circumstances.

In September, Tesla filed to begin operating its ride-hailing service at various airports in the Bay Area, including San Francisco International Airport, San Jose Mineta International Airport, and Oakland International Airport.

Tesla targets Bay Area airports as next step for Robotaxi rollout

It officially came through on that promise last night, as it announced its Bay Area ride-hailing service would now go to San Jose Mineta International Airport:

The expansion signals a key approval for Tesla to travel to one of the more popular places where people would need or simply want a drop-off. Airports are expensive to park in, so many people utilize ride-hailing services to enable a more economical experience from start to finish.

With this approval for SJC, Tesla will likely gain even more approvals for other airports in the Bay Area in the coming weeks or months.

While Tesla believes at least half of the U.S. population will have access to the company’s Robotaxi program or its ride-hailing service by the end of the year, the first step will be gaining approval in more metropolitan areas.

Tesla is looking to expand to other states, including Nevada, Florida, and Arizona, with its Robotaxi platform in the near future.
