SpaceX fires up Starship booster at orbital launch pad

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

Published

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 Robotaxi geofence expansion enters Plaid Mode and includes a surprise

Now, on August 26, the Robotaxi geofence has expanded once again, and is estimated to be about 130 square miles.

Published

Tesla has expanded its Robotaxi geofence in Austin for the third time since its launch in late June, and the company added a big surprise with this new service area.

After launching on June 22, Tesla’s driverless Robotaxi service has been expanded three times. Its initial launch was about 20 square miles in size. The first expansion occurred on July 14 and was roughly 42 miles large, more than double the initial geofence size.

The second expansion occurred on August 3 and brought the total service area to roughly 80 square miles.

Now, on August 26, the Robotaxi geofence has expanded once again, and is estimated to be about 170 square miles.

The expansion of the Robotaxi geofence seemed to show the company’s focus on getting the service to the areas East and West of downtown was an utmost priority.

We reported on the Bee Cave region of the Austin suburbs being a place where Robotaxi validation vehicles were spotted testing in recent days.

Bee Cave is included in the new geofence.

However, that is not the biggest addition to the geofence, and it’s not even close. Tesla added a major area to the new geofence, one that fans of the company will absolutely love: Tesla Gigafactory Texas.

The big question that remains is whether Tesla is expanding the size of its fleet of Robotaxi vehicles in Austin. There have been many questions about the expansions of the fleet and not necessarily the geofence, and while the latter is certainly considered progress, Tesla will need to enable more Robotaxi into the vehicle population to handle the additional rides.

Tesla has been planning to do so, but is still prioritizing safety and does not want to rush any part of the Robotaxi process.

Tesla is also looking to expand to new cities altogether. It is currently moving toward a Robotaxi launch in Florida, Arizona, and Nevada, and has also opened up job postings for Robotaxi operators in New York.

Elon Musk reiterates his most optimistic prediction yet with “UHI” forecast

Despite his polarizing nature, Elon Musk is, at his core, an optimist.

Despite his polarizing nature, Elon Musk is, at his core, an optimist. If he were not one, he would never have founded Tesla or SpaceX, or pursued projects such as Neuralink or xAI.

Musk’s optimism was on full display on social media platform X recently, when he shared what could very well be his most optimistic prediction yet.

Robots and humans

The Tesla CEO recently responded to a post from David Scott Patterson, who estimated that all jobs will be replaced by AI and robots easily by 2030. In his post, Patterson noted that if robots are sold at the same rate as vehicles, it could result in an output of 320 million robots per year. 

Musk responded that eventually, intelligent humanoid robots will far exceed the population of humans, and “there will be many robots in industry for every human to provide products & services.” 

Musk is already taking steps to achieve such a future. Tesla’s Optimus humanoid robot is expected to see its first “legion” produced this 2025. During an All-Hands meeting earlier this year, Musk also hinted to Tesla employees that the company will try to produce about 50,000 Optimus robots next year.

Universal High Income (UHI)

Musk has shared similar sentiments in the past, so it was no surprise that some X users asked the CEO how humans could sustain their lives when robots replace working individuals. To this, Musk responded that a Universal High Income (UHI) would be implemented, which should provide people with the best medical care, food, and transport available.

“There will be universal high income (not merely basic income). Everyone will have the best medical care, food, home, transport and everything else. Sustainable abundance,” Musk wrote in his post

Musk’s comment about sustainable abundance seems to be a prevalent theme in his recent optimistic comments. During Tesla’s second quarter earnings call, for example, Musk hinted that his Master Plan Part Four will describe a path towards sustainable abundance in a post-autonomy world.

New videos from Australia have fueled speculations that Tesla’s Full Self-Driving (FSD) will be rolling out in the country soon. 

The videos, which were shared widely on social media, showed Teslas navigating lane changes, slowing for traffic, and handling curves without driver input, but still with active supervision.

New FSD footage

One video, posted by lifestyle outlet Man of Many and narrated by journalist Ben McKimm, highlighted how quickly the system responded to real-world conditions. McKimm seemed quite impressed with FSD’s performance, stating that the vehicle performs maneuvers much like a human driver. 

Another video, which featured reporter Danielle Collin, featured a Tesla operating on public roads using its FSD (Supervised) system. Similar to McKimm, Collin seemed very impressed with the capabilities of FSD, as the vehicle was reacting to things like stop signs on its own. 

No regulatory barriers

This isn’t the first time the software has been seen on Australian roads. Earlier this year, Tesla released a clip of a Model 3 driving through Melbourne’s central business district with no visible driver input. A second video later surfaced from Sydney, reinforcing expectations that Australia could be among the first right-hand-drive markets to receive access.

According to Tesla’s Australian website, FSD (Supervised) uses 360-degree camera visibility to manage blind spots, execute lane changes, and maintain awareness of surrounding vehicles, cyclists, and motorcycles. While Tesla notes that constant human oversight is still required for now, FSD is designed to handle city intersections, multi-lane highways, and traffic signals.

In an earlier statement to news.com.au, Tesla country director Thom Drew previously confirmed there were “no blockers in Australia” for a supervised release of FSD, similar to North America. “It’s something our business is working on releasing,” Drew said, though he did not provide a timeline.
