Reuters reports that SpaceX has proposed modifying a second Florida launch pad to support Crew Dragon missions after NASA raised concerns about the threat posed by plans to launch Starship out of the only pad currently certified for Dragon.

After more than a year of downtime, SpaceX restarted the construction of an orbital Starship launch site at NASA’s Kennedy Space Center LC-39A pad in late 2021. SpaceX has leased Pad 39A since 2014 and conducted 49 Falcon rocket launches out of the facility since its first use in 2017. Prior to SpaceX’s lease, Pad 39A supported 82 Space Shuttle launches from 1981 to 2011 and every Apollo Program launch to the Moon in the 1960s and 1970s, making it one of the most storied and well-used launch sites in the history of US spaceflight.

In 2018, Pad 39A began supporting launches of SpaceX’s Falcon Heavy, which was and still is the most powerful and capable rocket currently in operation. In May 2020, a Falcon 9 rocket and Crew Dragon spacecraft lifted off with two NASA astronauts in tow, marking SpaceX’s first human spaceflight and the United States’ first domestic astronaut launch of any kind since 2011. The next era of the historic pad could include Starship, a fully-reusable two-stage rocket that SpaceX has been developing in earnest since the mid-2010s. However, NASA is worried that a failure of that immense and unproven rocket could almost instantly destroy what is currently the only launch pad on Earth capable of launching the space agency’s astronauts to the International Space Station (ISS).

One certainly can’t blame NASA for worrying. In its latest iteration, SpaceX’s Starship 39A launch mount will sit roughly 1000 feet (~300m) East of Pad 39A’s existing Falcon launch facilities, which include a tower and arm that are needed for astronauts and cargo to access and board Crew and Cargo Dragons. The Starship mount is also around 1600 feet (~500m) northeast of Pad 39A’s lone horizontal integration hangar, without which Falcon launch operations would become far more difficult or even impossible.

For the Falcon pad and tower, there is a slight consolation: Starship’s own skyscraper-sized launch tower will be located directly between those Falcon facilities and Starship before and during launches and could partially protect them from any hypothetical blast. The hangar will be fully unprotected, however.

NASA is worried that if a Starship fails before or shortly after launch and explodes at or near its adjacent launch mount, it could destroy or damage the infrastructure the space agency and SpaceX need to launch Crew Dragon to the International Space Station (ISS). At the moment, Boeing – NASA’s second Commercial Crew partner – is likely a year or more away from its first operational astronaut launch, during which Falcon 9 and Crew Dragon will remain a single point of failure that could theoretically sever the space agency’s connection to its own space station at any moment.

In response to NASA’s concern, NASA executive Kathy Lueders – in an interview with Reuters – says that SpaceX has begun working with the agency on plans to both “harden” Pad 39A and modify its Cape Canaveral Space Force Station (CCSFS) LC-40 pad to support Dragon launches. According to Reuters, however, receiving approval to put those plans into action “could take months.” Depending on how significant the facilities LC-40 would need are, there’s also a chance that SpaceX would need to complete a new FAA environmental review to construct a crew access tower.

Meanwhile, Pad 39A is also the only launch pad in the world capable of supporting Falcon Heavy, which has also become an extremely important rocket for uncrewed NASA spacecraft launches, NASA’s plans to get cargo to its lunar Gateway space station, and to the US military. Modifying one of SpaceX’s other pads to support Falcon Heavy would likely be even harder and take even longer than adding Crew Dragon capabilities to LC-40. In both cases, it’s likely that NASA and the US military would strongly prefer – if they don’t eventually outright require – that SpaceX have backup options already constructed and ready to go before risking the destruction of Pad 39A with its first Starship launch.

39A’s Starship facilities could easily require another 6-12 months of work before they’ll be ready for launch, however, leaving a good amount of time for SpaceX to alleviate the concerns of its US government customers before they might actually start to disrupt plans for East Coast Starship launches.

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.
