SpaceX seeks approval for Starlink internet tests on high-performance govt. planes

Published

According to updated regulatory documents and recent Aviation Week interviews with the US Air Force Research Laboratory, it can be all but guaranteed that the USAF has begun working with SpaceX to test the feasibility of using the company’s planned Starlink satellite internet constellation for military communications purposes.

In early August, SpaceX updated regulatory documents required by the Federal Communications Commission (FCC) for the company to be permitted to experimental test its two prototype Starlink internet satellites, named Tintin A and B. Launched roughly six months ago as a copassenger on one of SpaceX’s own Falcon 9 rockets, the satellite duo has been quietly performing a broad range of tests on orbit, particularly focused on general satellite operations, orbital maneuvering with SpaceX’s own custom-built electric propulsion, and – most importantly – the experimental satellites’ cutting-edge communications capabilities.

Per a public summary of the application update, SpaceX is awaiting FCC permission to begin a new series of tests of its prototype satellite internet network, this time highlighting an intriguing interest in applying Starlink connectivity to moving aircraft in order to provide them an exceptionally flexible and powerful suite of communications capabilities.

“SpaceX seeks to modify its experimental authorization to allow testing of two different antennas, both of which will operate on the ground and one of which will also operate from a moving aircraft.”

In those same documents, the company states that it is “working with a manufacturer of conformal antennas for tactical aircraft” to design and build “a custom installation kit consisting of mechanical plates for the low-profile antennas and fairings reducing wind drag”, seemingly indicating that SpaceX itself intends to supply the phased array antennae itself. Normally, this sort of testing would be fairly mundane and expected for any global satellite network, as one of the largest markets for satellite internet connectivity happens to be commercial aviation, particularly airlines and passenger entertainment.

However, the plot thickens beyond that extent thanks to a few select phrases. Most tellingly, the company writes that it “will perform a series of tests with the integrated airborne prototype terminal … varying motion for representative roll and pitch rates of a high-performance aircraft“, later also describing the program the update as a request for permission for “additional test activities undertaken with the federal government.”

It just so happens that the US Air Force’s Research Laboratory (AFRL) spoke with Aviation Week earlier this year (just weeks after SpaceX’s first prototype satellites had launched, in fact) about a nascent program exploring the potential utility of a spate of commercial Low Earth Orbit satellite internet constellations proposed for launch in recent years.

“To explore the art of the possible, AFRL is planning to contract with at least one commercial internet provider for a set of antennas that can be mounted onto Air Force test aircraft, Beal says. The team will then fly the aircraft … directly under the associated satellites and establish a communications path.”Lara Seligman/AviationWeek

As of publishing then (March 2018) and now, SpaceX is the only company in the world to have launched a pair of functional demonstration satellites as a part of its proposed megaconstellation, meaning that it’s the only company that has a (technically) operational network with which they can test inter-satellite connectivity, connection hand-offs between different satellites, and multi-satellite operations.

While it’s currently unclear how that series of tests transpired and if they were or are officially connected to the AFRL’s own program, the briefest thought of the USAF (and thus the Department of Defence) as a prospective anchor customer for SpaceX’s Starlink constellation is extraordinarily exciting, especially given the apparent difficulties and costs associated with actually deploying even the first wave (~900 satellites) of such a massive constellation (~4500 satellites total).

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.
