SpaceX’s South Texas Starship Mk1 prototype is on the verge of kicking off a critical period of ground tests, ranging from tank pressurization and propellant loading to the rocket’s first triple-Raptor engine static fire. The campaign could begin soon – perhaps as soon as later today, in fact.

Over the last two weeks, SpaceX’s South Texas team has faced bad winter weather, among the many other challenges associated with building giant rockets almost entirely out in the elements. Nevertheless, company technicians and engineers continue to check off task after task along the path towards Starship Mk1 completion, the next-generation launch vehicle’s first full-scale, high-fidelity prototype.

In the month of November alone, SpaceX has (re)installed Starship Mk1’s nose and aft section flaps (this time outfitted with heavy-duty actuator mechanisms), nearly completed the process of routing and integrating the vehicle’s external liquid and gas plumbing, and more or less finished a barebones launch mount. Starship Mk1 was snugly attached atop that launch mount around the start of the month and workers have continuously swarmed around the rocket and pad in scissor and boom lifts and ever since, closing out umbilical connections, insulating cryogenic propellant pipes, and much, much more.

Within the last week or so, SpaceX has apparently also begun the process of expanding its presence around its existing Boca Chica pad facilities, where Starship Mk1 is preparing for testing. The purpose of that expansion is unclear, but the first phase – extending the existing square landing pad – is essentially complete and will presumably give Starship Mk1 a better chance of successfully landing in the event that its first skydiver-style landing attempt is not as accurate as predicted.

Based on official renders/mockups in SpaceX’s updated 2019 launch animation, it could also eventually become the foundation of a much more permanent integration and processing hangar, much like the hangars that SpaceX uses to integrate Falcon 9 and Heavy at its Florida and California launch sites. It could even be the foundation for a dramatically larger Super Heavy-class launch mount and water-cooled flame deflector like the one shown in that same video. For now, Starship Mk1 will begin testing (and presumably first flights) off of a minimal steel mount that was built up from almost nothing in barely two months.

No nose, no problem?

As previously discussed on Teslarati, the testing Starship Mk1 is preparing for could take a number of routes to completion, but all of those routes will likely involve several main events. First, SpaceX may or may not decide to do a preliminary tank proof test with neutral (i.e. non-explosive) liquid nitrogen, which would verify the structural integrity and determine if there are leaks in what is essentially a building-sized pressure vessel.

SpaceX may instead skip that – it would require a vast and unwieldy quantity of liquid nitrogen – and move directly into the first cryogenic propellant loading test, in which SpaceX would attempt to fully fill Starship’s tanks with liquid oxygen and liquid methane. Assuming Starship Mk1 is 1:1 scale, that could involve as much as 1200 metric tons (2,650,000 lbs) of propellant, more than twice as much fuel as a Falcon 9.

In other words, Starship’s inaugural propellant loading attempt will be almost at the same scale as Falcon Heavy’s, which took several attempts, broke some hardware, and was a major learning experience and challenge on its own. A structural failure or explosion could be absolutely catastrophic, as those ~1200 tons of fuel and oxidizer could act as a massive bomb under the right conditions.

According to road closure notices published by Cameron County, SpaceX is expected to begin operations that require road closures as early as November 18th from noon to 8 pm CST, with backups on the 19th and 20th. Another window opens on the 25th at the same time, with backups on the 26th and 27th. To be clear, there is no official word that SpaceX actually means to start cryogenic ground testing with Starship Mk1 today, but it’s not necessarily out of the question.

Whenever SpaceX does decide to start Starship Mk1 ground testing, it will be an immensely important milestone, signifying the start of the period that will essentially determine whether SpaceX’s deeply unusual manufacturing methods can build a structurally-sound, high-performance rocket prototype for pennies on the dollar. In simple terms, if Starship Mk1 behaves as planned, commercial spaceflight may never be the same.

Elon Musk reveals Tesla’s next Robotaxi expansion in more ways than one

Tesla Robotaxi is growing in more ways than one. Tesla wants to expand and hopes to reach half the U.S. population by the end of the year.

Tesla CEO Elon Musk revealed the company’s plans for its next expansion of the Robotaxi in terms of both the geofence in Austin and the platform overall, as it looks to move to new areas outside of Texas.

Tesla launched the Robotaxi platform last month on June 22, and has since expanded both the pool of users and the area that the driverless Model Y vehicles can travel within.

The first expansion of the geofence caught the attention of nearly everyone and became a huge headline as Tesla picked a very interesting shape for the new geofence, resembling male reproductive parts.

The next expansion will likely absolve this shape. Musk revealed last night that the new geofence will be “well in excess of what competitors are doing,” and it could happen “hopefully in a week or two.”

Musk’s full quote regarding the expansion of the geofence and the timing was:

“As some may have noted, we have already expanded our service area in Austin. It’s bigger and longer, and it’s going to get even bigger and longer. We are expecting to greatly increase the service area to well in excess of what competitors are doing, hopefully in a week or two.”

The expansion will not stop there, either. As Tesla has operated the Robotaxi platform in Austin for the past month, it has been working with regulators in other areas, like California, Arizona, Nevada, and Florida, to get the driverless ride-hailing system activated in more U.S. states.

Tesla confirmed that they are in talks with each of these states regarding the potential expansion of Robotaxi.

Musk added:

“As we get the approvals and prove out safety, we will be launching the autonomous ride-hailing across most of the country. I think we will probably have autonomous ride-hailing in probably half the population of the US by the end of the year.”

We know that Tesla and Musk have been prone to aggressive and sometimes outlandish timelines regarding self-driving technology specifically. Regulatory approvals could happen by the end of the year in several areas, and working on these large metros is the best way to reach half of the U.S. population.

Tesla said its expansion of the geofence in Austin is conservative and controlled due to its obsession with safety, even admitting at one point during the Earnings Call that they are being “paranoid.” Expanding the geofence is necessary, but Tesla realizes any significant mistake by Robotaxi could take it back to square one.

Tesla warns customers of incentive strategy on EVs as tax credit nears end

If you’re thinking of buying a Tesla, the time to order is now, the company claimed.

Tesla has warned customers about its incentive strategy for qualifying electric vehicles, as the days of both the $7,500 EV tax credit for new EVs and the $4,000 credit for used EVs are coming to a close.

Both tax credits, which impact some of the vehicles in the Tesla lineup, are set to be eliminated at the end of Q3. The phase out of these consumer credits was always in the plans of the Trump Administration, but now we’re in the final quarter of their existence.

As a result, EV companies are scrambling to see how they can reduce costs or make their vehicles more affordable for customers. The $7,500 will price many consumers out of many EVs on the market, and Tesla is not immune to that.

However, Tesla has made a significant push into Q3 deliveries, rolling out numerous incentives to customers, including 0% APR on select purchases, lease deals, free upgrades on certain inventory units, and more.

The extensive list of incentives on Tesla vehicles in the quarter will not get any longer, either. During last night’s Tesla Earnings Call for the second quarter of 2025, company executives stated that their intention for these incentives was to encourage customers to place orders early in the quarter.

Tesla will only be able to apply the $7,500 credit with deliveries that occur before the end of September. Even if an order is placed before then, delivery must be completed by September 31 to receive the tax credit.

CFO Vaibhav Taneja confirmed that the incentives for the quarter are already out and encouraged customers to place an order sooner rather than later:

“Given the abrupt change, we have a limited supply of vehicles in the US this quarter. As we are already within lead times to order parts for cars, we have rolled out all our planned incentives already and will start pairing them back as we start to sell. If you are in the US and looking to buy a car, let’s roll now as we may not be able to guarantee delivery for orders placed in the later part of August and beyond.”

The loss of the incentives will impact every EV maker in the United States. Tesla has a plan moving forward, and it said last night that its affordable models would be rolled out in Q4, as introducing these cars any earlier could have detrimental effects on Model 3 and Model Y sales.

Tesla Model Y awarded Top Safety Pick+ from IIHS

The new Model Y continues to impress with this new award.

The 2025 Tesla Model Y was one of two midsize luxury SUVs to receive the Top Safety Pick+ award from the Insurance Institute for Highway Safety (IIHS).

To qualify for the IIHS’s Top Safety Pick+ or even the lower-tier Top Safety Pick label, vehicles need good ratings in the small overlap front and side crash tests, an acceptable or good rating in the pedestrian front crash prevention evaluation, and acceptable or good ratings for headlights across all trim levels.

The difference between the two labels is that an “Acceptable” rating in the moderate overlap front test will get a car the Top Safety Pick rating, but a “Good” rating in this category will win the elusive Top Safety Pick+ category.

The 2025 Model Y, codenamed “Juniper” internally by Tesla, was released in the United States earlier this year and received the top rating across each of the categories, automatically qualifying it for the Top Safety Pick+ label:

Other vehicles in Tesla’s lineup have extraordinary marks in crash testing according to other agencies, like the National Highway Traffic Safety Administration (NHTSA), but there are reasons those cars are not on the IIHS lists.

In 2024, we reported that the IIHS had evaluated some Tesla vehicles for the necessary tests to achieve these marks. Joe Young of the agency told us that the Model 3, for example, was not featured on either the Top Safety Pick or Top Safety Pick+ lists because the vehicle had several missing tests.

Here’s why the Tesla Model 3 wasn’t an IIHS Top Safety Pick+, and why it could be soon

This is not to say those other Tesla vehicles would not perform well. The Cybertruck performed better than any pickup has ever in NHTSA crash testing assessments.

The Model Y is Tesla’s most popular vehicle and was the best-selling car in the world over the past two years. Tesla’s intense focus on safety continues to show that this priority goes into every decision the company makes regarding design and engineering. This focus has continued to pay dividends as some real-world crashes save the lives of those inside the cars.
