SpaceX fires up Starship booster at orbital launch pad
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.

Tesla China achieves this year’s second highest domestic sales in June
The figure represents Tesla’s second-best performance in 2025 so far.
Domestic sales for Tesla China reached 61,484 units in June, marking a sharp recovery from recent months and positioning the company for a stronger finish to the second quarter. The figure represents Tesla’s second-best performance in 2025 so far, trailing only March, when the company delivered 74,127 vehicles domestically.
A strong comeback for Tesla China
According to data from the China Passenger Car Association (CPCA), Tesla sold a total of 71,599 cars wholesale in June 2025. This means that Tesla’s domestic sales last month rose 59.3% compared to May’s 38,588 units and increased 3.75% year-over-year from 59,261 units in June 2024, as noted in a CNEV Post report.
The rebound ends a two-month streak of year-over-year declines and helped lift Tesla’s Q2 retail total in China to 128,803 units, though that still marks an 11.7% drop from the same period last year. For context, Tesla China sold 263,410 vehicles domestically, down 5.36% year-over-year, in the first six months of 2025.
Tesla’s stronger domestic showing in June came as the company scaled back its export output from Giga Shanghai. The factory exported 10,115 vehicles last month, down 56.2% from May and 13.9% from a year earlier. For the first half of 2025, Tesla China’s total exports reached 101,064 units, down 31.85% compared to the same period in 2024.
Tesla China’s 2025 performance
June saw continued growth across China’s broader new energy vehicle (NEV) market, with retail sales reaching 1.11 million units, up 29.7% year-over-year. Battery electric vehicles (BEVs) accounted for 661,000 of those sales. Tesla’s NEV market share for June was then 5.53%, down from 6.92% a year earlier but an improvement over May’s 3.78%.
The Model Y continues to be Tesla China’s primary driver of sales, with the vehicle’s wholesale figures reaching 51,253 units in June, up 16.6% from a year ago and nearly 30% from May. Wholesale numbers for the Model Y totaled 214,034 units in the first six months of the year. The Model 3, in comparison, saw wholesale volumes reach 150,440 units in the first six months of the year.

Elon Musk confirms Grok 4 launch on July 9 with livestream event
The rollout will be accompanied by a livestream at 8 p.m. Pacific Time.
Elon Musk has officially confirmed that Grok 4, the latest version of xAI’s large language model, will launch on July 9. The rollout will be accompanied by a livestream at 8 p.m. Pacific Time, hosted on xAI’s official account on X.
xAI goes straight to Grok 4
Back in May, leaks indicated that xAI was getting ready to ship Grok 3.5. Considering Musk’s recent comments, however, it appears that the artificial intelligence startup would be focusing on the large language model’s fourth iteration instead. As noted in a Financial Express report, users on X have sighted references to Grok 4 in the lead up to the update’s launch, such as “grok-4-prod-mimic” and “Grok 4 Code.”
Musk’s Grok 4 announcement comes as AI competition intensifies between major players including OpenAI, Google, and xAI. With Musk’s Colossus supercomputer fully operational in Memphis, xAI appears to be accelerating its AI product roadmap.
Musk pushes Grok toward political neutrality
Grok 4’s launch also follows a recent controversy involving political bias, as noted in a CNN report. Last week, Grok responded to a user on X stating that political violence in the U.S. since 2016 had come more from the political right than the left. The chatbot noted in a later reply that its answer was based on information from sources like Reuters, the Journal of Democracy, and University of Maryland studies.
Musk stated that Grok’s response was a “major fail.” “Major fail, as this is objectively false. Grok is parroting legacy media. Working on it,” he wrote in a post on X. By the end of June, Musk noted that he was “grinding all night with the xAI team” and that they were making “good progress.” He also stated that the model “Will be called Grok 4. Release just after July 4th. Needs one more big run for a specialized coding model.”

Tesla opens massive solar Supercharger station in California
The Supercharger opened to customers ahead of Fourth of July weekend, while Tesla continues phase two of construction on the site.
Tesla has officially launched the first several Supercharging posts at a massive station in California, notably including solar canopies and grid-scale batteries to offer completely renewable charging.
Last week, Tesla announced on X that it opened the first 84 Supercharger stalls of a planned 168-stall station in Lost Hills, California. Additionally, the massive Supercharger project features 11MW of solar canopies and 10 Megapack batteries for off-grid charging powered entirely by solar energy.
Tesla completed the first phase of the project just days ahead of the busy Fourth of July holiday weekend, adding that initial construction took just eight months. In addition to the remaining charging stalls, Tesla says it’s building a set of lounge areas, renderings of which can be seen below alongside current photos of the site.
Notably, the site also includes V4 charging posts for the company’s latest available charging speeds, and it’s located near the busy junction between I-5 and Highway 46 in Kern County.
“Thank you [Kern County] and [PG&E] for collaboration and approvals,” Tesla wrote in a follow-up post.

Testing at the LA Diner, plus Musk update on potential Tesla solar Gigafactory
The huge Tesla Supercharger station completed phase one of construction fairly quickly, especially given how long Tesla has been working on its unique Los Angeles diner, drive-in, and Supercharger location. Still, the company was seen performing some testing at the nearly-completed charging station earlier this month, and will reportedly be holding a job fair.
Elon Musk also responded on Monday morning to a post on X, suggesting that Tesla is “thinking about” building a U.S.-based solar Gigafactory in order to help support increased power needs with AI growth, and to bolster domestic solar production.
