SpaceX installs Super Heavy booster on launch mount with giant robot arms
SpaceX has transported the most powerful rocket booster ever assembled to its Starbase orbital launch site (OLS) and used giant robotic arms to install it.
It’s not the first such trip for Starship’s Super Heavy first stage in general, nor for this specific booster, which is known as Booster 7 or B7. Booster 7 first headed to the pad on March 31st and successfully completed two major cryogenic proof tests, but was then severely damaged during a subsequent structural stress test. After a few weeks of repairs back at the factory, B7 rolled to the pad a second time and completed a third cryoproof test and returned to the factory on May 14th, where it stayed until June 23rd.
After almost six weeks of additional work, Booster 7 rolled to the launch pad for the third time – possibly its last trip.
Even Booster 7’s first rollout wasn’t unprecedented, however. In September 2021, Booster 4 – an earlier prototype with fewer engines, less thrust, and several other differences – arrived at the launch site with 29 Raptor V1 engines installed. Over the next six months, SpaceX slowly finished the booster, conducted a handful of proof tests, and eventually performed three ‘full-stack’ tests with Starship S20. For awhile, SpaceX hoped to eventually fly B4 and S20 on Starship’s first orbital launch attempt, but that plan never came close to fruition.
Booster 4 was particularly underwhelming and never even attempted a single static fire despite having all 29 of its engines fully installed and encased inside a shell-like heat shield. Thankfully, Booster 7 appears to have a much better chance of at least attempting one or several static fires, even if there’s no guarantee that it will make it through that test campaign in good enough condition to support Starship’s orbital launch debut.
SpaceX used the six weeks Booster 7 spent back in a factory assembly bay to finish installing aerocovers, surfaces known as chines or strakes, car-sized grid fins, Starlink internet dishes, and – most importantly – 33 upgraded Raptor V2 engines. Combined, Booster 7 should be able to produce up to 7600 metric tons (~16.8M lbf) of thrust – 41% more thrust than Booster 4 was theoretically capable of. Crucially, SpaceX also finished installing Booster 7’s Raptor heat shield in the same period, completing in six weeks work that took Booster 4 more like half a year.
That is likely because testing Booster 4, for whatever reason, just wasn’t a priority for SpaceX. Preparing Booster 7 for static fire testing, however, is clearly a front-and-center priority in 2022. With its heat shield and all 33 Raptors installed, Booster 7 will be ready to kick off static fire testing almost as soon as it’s installed on Starbase’s orbital launch mount.
According to CEO Elon Musk, Booster 7 will start by igniting just one or a few Raptor engines. SpaceX has never ignited more than six Raptor V1 engines simultaneously and never tested more than three engines at a time on a Super Heavy booster. That plan could have easily changed, however. Either way, Super Heavy B7 will be treading significantly new ground. Even before actual static fires begin, Booster 7 will also need to complete one or more wet dress rehearsals (WDRs), a test that exactly simulates a launch but stops just before the moment of ignition.
If SpaceX attempts a full wet dress rehearsal, in which the booster would be filled with more than 3000 tons (~6.6M lb) of liquid oxygen (LOx) and liquid methane (LCH4), it would be a first for Super Heavy and just as big of a test of the orbital launch site. Booster 7 will also need to test out its autogenous pressurization, which replaces helium with hot oxygen and methane gas to pressurize the rocket’s propellant tanks.
Several hours after Super Heavy B7 arrived (for the third time) at the orbital launch site, SpaceX used two giant arms attached to the pad’s launch tower to lift the ~70-meter (~230 ft) tall rocket onto the launch mount. While Musk says that the ultimate goal is to use those arms to catch Starship and Super Heavy out of mid-air, their current purpose is to take the place of the tall and unwieldy crane that would otherwise need to be used to lift either stage. The arms are an extremely complex solution but they do allow SpaceX to lift, install, and remove Starship stages remotely and insulate those processes from wind conditions, which cranes are sensitive to.
Once fully secured by the mount’s 20 hold-down clamps, the booster will be connected to ground systems and SpaceX can prepare B7 to start the next stage of preflight testing as early as Monday, June 27th.
Tesla has lost its Model Y Program Manager, he announced on LinkedIn, marking the second major departure from the company today.
Emmanuel Lamacchia has been in the role for 4 years and 7 months, responsible for the rollout of the all-electric crossover in several markets.
The Model Y became the best-selling vehicle in the world for two years under Lamacchia’s watch, making this a huge loss for the company. However, it seems the decision was made under Lamacchia’s own initiative.
He confirmed his decision on LinkedIn:
“After 8 incredible years, I’m moving on from Tesla.
What a journey it’s been… from leading NPI for Model 3 and Model Y variants to becoming the Vehicle Program Manager for Model Y, the best-selling car in the world!
Leading the All-New Model Y launch was the highlight: converting all 4 factories across 3 continents in just 2 weeks. Something that had never been done before in the auto industry.
To the teams who made this possible: you should be incredibly proud. This achievement belongs to you: the engineers, designers, buyers, and associates in Fremont, Shanghai, Berlin, and Austin who turned an impossible timeline into reality.
Grateful to the leaders who trusted me with programs that stretched my capabilities and to the cross-functional partners who showed me that great solutions come from collaboration, not hierarchy.
Tesla taught me how to move fast without breaking things and how to scale from prototypes to millions of units.
Excited for what’s next. More to share soon.”
It marks the second major program loss for Tesla today, as it also bid farewell to Cybertruck and Model 3 Program Manager Siddhant Awasthi, who said he left voluntarily in “one of the hardest decisions of his life.”
Lamacchia was at Tesla for just a shade under eight years, and previously worked for Rolls-Royce for roughly the same amount of time.
After the loss of both Lamacchia and Awasthi today, Tesla has lost a handful of key executives in 2025, including:
- David Imai, Director of Design
- David Lau, VP of Software Engineering
- Mark Westfall, Head of Mechanical Engineering
- Prashant Menon, Regional Director in India
- Vineet Mehta, Head of Battery Architecture
- Omead Afshar, VP/Head of Sales and Manufacturing in North America
- Milan Kovac, Head of Optimus Team
- Jenna Ferrua, Director of HR
- Troy Jones, VP of Sales, Service, and Delivery
- Pete Bannon, VP of Hardware Engineering
- Piero Landolfi, Director of Service

Tesla prepares to expand Giga Texas with new Optimus production plant
Drone operator Joe Tegtmeyer recognized Tesla construction crews performing ground leveling and clearing efforts at the plant earlier today.
Tesla is preparing to expand Gigafactory Texas once again with a brand new facility that will house the eventual manufacturing efforts for Optimus, its humanoid robot.
It is already building some units on a Pilot line at the Fremont Factory in Northern California, but Tesla is planning to build the vast majority of its Optimus project at Gigafactory Texas.
Tesla Optimus gets its latest job, and it’s not in the company’s factories
It will build one million units per year in Fremont, but CEO Elon Musk said the company would build 10 million units every year in Texas at a new building at Giga Texas.
Musk said:
“I think there could be tens of billions of Optimus robots out there. Um, now obviously it’s very important we pay close attention to safety here. Then a 10 million unit uh per year production line here the I don’t know where we’re going to put the 100 million unit production line. on Mars. Maybe on Mars, I don’t know.”
Evidently, Tesla is ready to begin thinking about the production efforts of Optimus beyond a theoretical standpoint and is starting to prepare for the construction of the manufacturing plant on Giga Texas property.
Drone operator Joe Tegtmeyer recognized Tesla construction crews performing ground leveling and clearing efforts at the plant earlier today:
Giga Texas News!
A brand-new, stand-alone factory is starting construction! This follows the Shareholders meeting & info that a 10-million-per-year @Tesla_Optimus production facility “on the Giga Texas campus” will be built & enter into production in 2027!
Here are some… pic.twitter.com/7ig5DohfOt

Production is still slated for 2027, at least at Gigafactory Texas. As previously mentioned, the company is building some units in Fremont for the time being, at least until subsequent versions of the Optimus project advance.
Tesla has done a great job of advancing Optimus forward, but it also has truly grand expectations for the project.
Musk said it could potentially be the biggest product in the history of the planet, as it will revolutionize the way humans perform tasks, probably eliminating monotonous tasks from everyday life.
Tesla revealed its first customer for the all-electric Semi truck after it launches next year. Who it truly is should not be a surprise.
The Semi is going to finally start deliveries to new companies outside of Tesla’s pilot program starting in 2026. The company has been building a dedicated production facility in Reno, Nevada, that has finally taken shape, but Tesla was evidently not finished with the Semi’s development.
Last week at the Annual Shareholder Meeting, Tesla said it had implemented some new designs into the Semi, helping with efficiency, updating its design, and making it a more suitable vehicle for hauling loads, as the changes also helped increase payload.
Tesla has obtained a lengthy list of companies that have committed to implementing the Semi in their own fleets, hoping to bring their logistics lineups up to date with electric powertrains and autonomous technologies.
While it is already operating a pilot program with PepsiCo. and Frito-Lay, Tesla will expand to other businesses, primarily using it internally after its launch.
Head of the Semi program at Tesla, Dan Priestley, said the company would be the first user of the vehicle after its launch next year. It has been using it to a certain extent, but the company has not been able to completely abandon gas haulers.
Instead, it will implement the Semi into its fleet for more sustainable vehicle logistics starting next year:
Tesla will be the first customer as we electrify our supply chain. This includes Texas operations.

Tesla has already received orders for the Semi from a variety of large companies, including Walmart, Sysco, Anheuser-Busch, UPS, DHL, J.B. Hunt, among others.
Many analysts see the Tesla Semi as a major contributor to future growth and increasing value within the company, especially from a Wall Street perspective. Some firms say the Semi is one of several near and medium-term contributors to the company increasing its market cap.
Cantor Fitzgerald is just one of those firms, as last week it explicitly listed the Semi as a catalyst.
Analyst Andres Sheppard said, “Overall, we remain bullish on TSLA over the medium to long term. We continue to see meaningful future upside from Energy Storage & Deployment, FSD, Robotaxis/Cybercab, Semis, and Optimus Bots.”
