After a brief pause, SpaceX is once again shipping pad hardware from its Boca Chica, Texas rocket factory to Starship’s rapidly growing orbital launch site (OLS).

A few days of delays aside, the latest transport simultaneously rolled a massive 12m (40 ft) wide water tank and another prefabricated section of SpaceX’s skyscraper-sized orbital launch tower to a nascent orbital launch site adjacent to two well-worn suborbital pads.

Those suborbital pads have been through dozens of ground tests of Starship test tanks, hoppers, and high-altitude prototypes over the last ~20 months, recently culminating in Starship SN15 launching to 10 km (6.2 mi), free-falling back to earth, and becoming the first prototype of its kind to successfully touch down. Since that May 5th milestone, Starship SN15 has been moved to an empty lot – likely to be put permanently on display – and SpaceX’s focus has quite clearly shifted towards Starship’s first orbital test flights.

To even be able to attempt those test flights, which will involve a Starship installed on top of the world’s most powerful rocket booster, several things must be in order. Relative to the three-engine, medium-altitude Starship prototypes SpaceX has the most experience with, CEO Elon Musk has implied that even the very first flightworthy Super Heavy boosters will be outfitted with 29 Raptor engines, representing an almost order-of-magnitude leap in lift-off thrust. In other words, SpaceX’s proven suborbital launch mounts are wholly inadequate for even a rudimentary orbital launch attempt.

Aside from being unable to withstand the immense stress of at least ~5800 metric tons (12.8 million lbf) of thrust, SpaceX’s suborbital pad also has far too little propellant storage capacity to fuel an orbital launch attempt. Enter SpaceX’s first South Texas orbital launch site.

In response, SpaceX has been gradually building out brand new orbital-class launch facilities for around nine months. Work on the pad began to significantly accelerate earlier this year, including the delivery of Starship-derived propellant storage tanks, the rapid assembly of even larger insulation ‘sleeves’ for those custom tanks, the even faster construction of multiple prefabricated launch tower segments, finishing touches on a tall six-legged ‘launch mount,’ the completion of a massive cryogenic propellant pumphouse, miles of wire and pipe runs, and far more.

As it turns out, the second propellant storage tank ‘sleeve’ is actually a massive water tank, indicating that Starship’s first orbital launch site will have some form of water deluge system to limit the damage Super Heavy’s 29 Raptors can do to the pad and rocket itself at liftoff. The tank measures 12m (40ft) wide and approximately 36m (~120ft) tall, meaning that it should be able to hold more than a million gallons (~4000 cubic meters) of water.

Additionally, SpaceX delivered the third prefabricated launch tower segment, leaving the tower more than half its full ~143m (469ft) height once installed. Two more sections are already more than half finished, likely meaning that the tower’s structural skeleton could be fully assembled by July or August.

Tesla teases new market entrance with confusing and cryptic message

Tesla teased its entrance into a new market with a confusing and what appeared to be cryptic message on the social media platform X.

The company has been teasing its entrance into several markets, including Africa, which would be a first, and South America, where it only operates in Chile.

In September, Tesla started creating active job postings for the Colombian market, hinting it would expand its presence in South America and launch in a new country for the first time in two years.

Tesla job postings seem to show next surprise market entry

The jobs were related to various roles, including Associate Sales Manager, Advisors in Sales and Delivery, and Service Technicians. These are all roles that would indicate Tesla is planning to launch a wide-scale effort to sell, manage, and repair vehicles in the market.

Last night, Tesla posted its latest hint, a cryptic video that seems to show the outline of Colombia, teasing its closer than ever to market entry:

This would be the next expansion into a continent where it does not have much of a presence for Tesla. Currently, there are only two Supercharger locations on the entire continent, and they’re both in Chile.

Tesla will obviously need to expand upon this crucial part of the ownership experience to enable a more confident consumer base in South America as a whole. However, it is not impossible, as many other EV charging infrastructures are available, and home charging is always a suitable option for those who have access to it.

Surprisingly, Tesla seems to be more concerned about these middle-market countries as opposed to the larger markets in South America, but that could be by design.

If Tesla were to launch in Brazil initially, it may not be able to handle the uptick in demand, and infrastructure expansion could be more difficult. Brazil may be on its list in the upcoming years, but not as of right now.

Tesla expands crucial Supercharging feature for easier access

It is a useful tool, especially during hours of congestion. However, it has not been super effective for those who drive non-Tesla EVs, as other OEMs use UI platforms like Google’s Android Auto or Apple’s iOS.

Tesla has expanded a crucial Supercharging feature that helps owners identify stall availability at nearby locations.

Tesla said on Tuesday night that its “Live Availability” feature, which shows EV owners how many stalls are available at a Supercharger station, to Google Maps, a third-party app:

Already offering it in its own vehicles, the Live Availability feature that Teslas have is a helpful feature that helps you choose an appropriate station with plugs that are immediately available.

A number on an icon where the Supercharger is located lets EV drivers know how many stalls are available.

It is a useful tool, especially during hours of congestion. However, it has not been super effective for those who drive non-Tesla EVs, as other OEMs use UI platforms like Google’s Android Auto or Apple’s iOS.

Essentially, when those drivers needed to charge at a Supercharger that enables non-Tesla EVs to plug in, there was a bit more of a gamble. There was no guarantee that a plug would be available, and with no way to see how many are open, it was a risk.

Tesla adding this feature allows people to have a more convenient and easier-to-use experience if they are in a non-Tesla EV. With the already expansive Supercharger Network being available to so many EV owners, there is more congestion than ever.

This new feature makes the entire experience better for all owners, especially as there is more transparency regarding the availability of plugs at Supercharger stalls.

It will be interesting to see if Tesla is able to expand on this new move, as Apple Maps compatibility is an obvious goal of the company’s in the future, we could imagine. In fact, this is one of the first times an Android Auto feature is available to those owners before it became an option for iOS users.

Apple owners tend to get priority with new features within the Tesla App itself.

Elon Musk’s Boring Co goes extra hard in Nashville with first rock-crushing TBM

The Boring Company’s machine for the project is now in final testing.

The Boring Company is gearing up to tackle one of its toughest projects yet, a new tunnel system beneath Nashville’s notoriously tough limestone terrain. Unlike the soft-soil conditions of Las Vegas and Austin, the Music City Loop will require a “hard-rock” boring machine capable of drilling through dense, erosion-resistant bedrock. 

The Boring Company’s machine for the project is now in final testing.

A boring hard-rock tunneling machine

The Boring Company revealed on X that its new hard-rock TBM can generate up to 4 million pounds of grip force and 1.5 million pounds of maximum thrust load. It also features a 15-filter dust removal system designed to keep operations clean and efficient during excavation even in places where hard rock is present.

Previous Boring Co. projects, including its Loop tunnels in Las Vegas, Austin, and Bastrop, were dug primarily through soft soils. Nashville’s geology, however, poses a different challenge. Boring Company CEO and President Steve Davis mentioned this challenge during the project’s announcement in late July.

“It’s a tough place to tunnel, Nashville. If we were optimizing for the easiest places to tunnel, it would not be here. You have extremely hard rock, like way harder than it should be. It’s an engineering problem that’s fairly easy and straightforward to solve,” Davis said.

Nashville’s limestone terrain

Experts have stated that the city’s subsurface conditions make it one of the more complex tunneling environments in the U.S. The Outer Nashville Basin is composed of cherty Mississippian-age limestone, a strong yet soluble rock that can dissolve over time, creating underground voids and caves, as noted in a report from The Tennessean.

Jakob Walter, the founder and principal engineer of Haushepherd, shared his thoughts on these challenges. “Limestone is generally a stable sedimentary bedrock material with strength parameters that are favorable for tunneling. Limestone is however fairly soluble when compared to other rack materials, and can dissolve over long periods of time when exposed to water. 

“Unexpected encounters with these features while tunneling can result in significant construction delays and potential instability of the excavation. In urban locations, structures at the ground surface should also be constantly monitored with robotic total stations or similar surveying equipment to identify any early signs of movement or distress,” he said.
