SpaceX has kicked off a record-breaking 2020 launch manifest with a spectacular combination of Starlink satellites and a Falcon 9 rocket, the first of perhaps two dozen such launches planned this year alone.

Falcon 9 booster B1049 supported the mission, becoming the second SpaceX rocket ever to complete four launches and landings after B1048 did it first in November 2019. Starlink-2’s Falcon 9 booster is now safely aboard drone ship Of Course I Still Love You and beginning the 600 km (375 mi) journey back to Port Canaveral, Florida, where it will likely be processed and turned around for a fifth launch in the near future.

Teslarati photographer Richard Angle was on-site to capture the event and caught a number of spectacular photos of SpaceX’s Starlink-2 launch, ranging from an excellent visualization of the rocket’s trajectory to a close-up view highlighting the fury of Falcon 9’s nine Merlin 1D engines seconds after liftoff.

Falcon 9 Block 5 boosters are loaded with some 520 metric tons (1.2 million lb) of liquid oxygen, refined kerosene (RP-1), helium, and nitrogen. At full throttle, the nine Merlin 1D engines that power each Falcon booster can produce more than 7600 kN (1.7 million lbf) of thrust, equivalent to more than 60 737 passenger jets chained together. At the same time, every one of those nine Merlin 1D engines likely consumes more than 270 kg (600 lb) of liquid oxygen and kerosene every second, with all nine engines combining to burn the equivalent of one and a half Tesla Model 3s worth of propellant per second.

A step further, the 1.5 Teslas of propellant Falcon 9 boosters burn each second exits the nozzles of their nine Merlin 1D engines traveling almost 3 kilometers per second (1.9 miles per second) – more than 35 times faster than the fastest hurricane windspeeds every recorded. In simple terms, the exhausts of even tiny orbital-class rockets create a spectacularly violent and unearthly environment in the seconds immediately following liftoff, exaggerated by the ground and pad hardware reflecting all that energy and fury.

And Falcon 9 (let alone Falcon Heavy) is no tiny rocket. While it’s still extremely difficult to get a good sense of scale while looking at launch photos, it’s safe to say that photos of Falcon 9’s nine Merlin 1D engines shortly after launch undeniably capture at least a small sense of the sheer heat, fury, and stress experienced by SpaceX’s orbital launch pads. One of the most obvious features are giant clouds backlit by the rocket’s own engines, produced as a side effect of the common use of water deluge systems to protect launch pads and keep launch vehicles from damaging themselves.

In the handful seconds the rocket is near the pad, swimming pools worth of water are almost instantaneously vaporized by into superheated steam clouds by its exhaust and then violently buffeted by the shockwaves and vibrations they produce. In simple terms, the sound alone – let alone the heat or debris kicked up by the exhaust – would likely kill or at least severely injure an unprotected human observer standing nearby, while the heat would probably incinerate immediate bystanders.

Regardless of the pedantry of observing rocket launches up close and really personal, January 6th’s Starlink launch is the first of as many as 36 launches SpaceX has planned in 2020 – some two dozen of which could end up being dedicated Starlink missions. SpaceX’s next two Starlink launches – Starlink-3 and -4 – are already scheduled to lift off as early as later this month.

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.
