Update: Less than five days after Starship serial number 10 (SN10) briefly became the first prototype to launch and land in one piece, SpaceX has rolled its successor – Starship SN11 – from factory to launch pad.

The goal: complete cryogenic proof and static fire testing within the next 4-7 days to clear the way for another Starship launch as early as next week. Already outfitted with three Raptor engines, SN11 may have a limited chance of hitting SpaceX’s ambitious schedule targets, but the experiences of Starships SN8, SN9, and SN10 suggest that a launch sometime before the end of March is a more reasonable expectation. Stay tuned for updates as SpaceX prepares to install Starship SN11 at the launch pad and put its cryogenic proof test on the calendar.

NASASpaceflight.com reports that SpaceX – already scheduled to transport a new Starship to the launch pad on Monday, March 8th – wants that prototype ready to launch as early as next week.

According to the same report, SpaceX – having already installed three Raptor engines on Starship serial number 11 (SN11) – aims to more or less wrap up all qualification testing by the end of the week. No different than the test campaigns that all other flightworthy Starships had to pass before being cleared for launch, that process includes – at minimum – a good cryogenic proof test and a combined wet dress rehearsal (WDR) and static fire.

Excluding Starhopper, of the five Starship prototypes that have taken flight, SpaceX has consistently managed to speed up the process of preparing each vehicle for flight, but the average time spent from rollout to liftoff is still more than a month. In other words, even accounting for the general improvements SpaceX seems to make between tests, readying Starship SN11 for flight within a week or two of the prototype arriving at the launch pad would be anywhere from a factor of two to five faster than any prior test campaign.

Excellent data recent collated by a new Twitter account (@BocaCharts) exemplifies both SpaceX’s continuous improvement and the unlikelihood of SN11 being ready for flight by next week.

Still, it’s not entirely impossible. If SpaceX can borrow from the most efficient Starship launches and test campaigns its completed and combine them all with a few new, unspecified efficiencies, it’s reasonable to conclude that Starship SN11 could be ready to fly near the end of next week (around March 19th). More specifically, SpaceX would have to complete a successful static fire on the first try within a week of SN11’s scheduled March 8th rollout, followed by a brisk two or three-day turnaround for a launch attempt.

While not impossible, it’s safe to say that that scenario is unlikely. Nevertheless, assuming SpaceX continues to find ways to expedite preflight processing like it has with SN8, SN9, and SN10, it’s reasonable to assume that Starship SN11 could be ready for an inaugural launch attempt as early as the last week of March.

All the above ignores the possibility that SpaceX will choose to physically modify Starship SN11 to mitigate the possibility of some or all aspects of Starship SN10’s hard landing and subsequent explosion from recurring. If that is the plan, those changes will have to be done at the launch site after Starship SN11’s scheduled Monday, March 8th rollout.

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.
