Update: After spinning itself around its vertical axis a bit like a propeller, SpaceX’s expendable Falcon 9 upper stage has successfully released a massive stack of 60 Starlink v1.0 satellites for the second time in two months. Designing to tolerate the occasional bump during their bizarre deployment, those 60 satellites will quickly spread out in space and deploy their solar arrays an hour or so after separating from Falcon 9’s upper stage.

Perhaps as early as later this evening or sometime on January 7th, all 60 satellites will fire up their krypton ion thrusters, beginning the process of temporarily raising their orbits to 350 km (220 mi). Once there, SpaceX will more extensively verify the health of each spacecraft and – if all looks well – send all 60 on their way to a final circular 550 km (340 km) orbit where they will join their brethren and begin operating as communications satellites.

A SpaceX Falcon 9 has kicked off what could be a record-smashing year, potentially making SpaceX the world’s most prolific launch company thanks in large part to the game-changing reusability of its Falcon rockets.

At 9:19 pm ET on January 6th (02:19 UTC, Jan 7), Falcon 9 booster B1049’s nine Merlin 1D engines came to lift, lifting the two-stage rocket and its payload of 60 Starlink satellites off the pad and sending them on their way to orbit. Minutes later, the Falcon 9 booster shut off – completing its fourth successful launch in 17 months – and flipped around with small cold-gas thrusters, beginning its trip back down to Earth.

Less than nine minutes after lifting off from SpaceX’s LC-40 pad at Cape Canaveral Air Force Station (CCAFS), Falcon 9 B1049 began its landing burn and gently touched down on drone ship Of Course I Still Love You (OCISLY), stationed more than 600 km (375 mi) downrange in the Atlantic Ocean. Seconds later, the mission’s expendable Falcon 9 upper stage shut off its Merlin Vacuum (MVac) engine, completing the first of two burns and placing the rocket and its Starlink payload in a parking orbit.

Known as Starlink V1 L2, referring to the second launch of Starlink v1.0 satellites, this mission crossed off several SpaceX milestones – both internal and external. For Falcon 9, it marked the company’s 48th successful landing of an orbital-class rocket booster, as well as the second time SpaceX has successfully launched and landed the same booster (this time B1049) four times in a row.

Even more significantly, it’s almost certain that – so long as all 60 Starlink V1 L2 satellites successfully deploy and begin orbit-raising – SpaceX will have become the owner and operator of the world’s largest commercial satellite constellation. After tonight’s launch, SpaceX’s Starlink internet constellation will likely measure some 175 operational satellites strong less than eight months after the company began dedicated internal launches.

Assuming drone ship OCISLY safely returns Falcon 9 B1049 to port and including SpaceX’s successful November 2019 Starlink V1 L1 launch, the company now possesses two Falcon 9 boosters – B1048 and B1049 – that have successfully performed four separate orbital-class launches apiece. With two rockets in hand, SpaceX should be able to far more accurately determine just how well they’re standing up to the rigors of the latest reusability milestone, hopefully giving the company the data it needs to rapidly turn around one or both boosters for a fifth launch in the near future.

SpaceX has 20-24 Starlink launches planned for 2020, so the company will have a wealth of opportunities to push its fleet of reusable rockets to their limits, ranging from attempting nth booster reuses to testing and expanding the envelope of SpaceX’s nascent payload fairing reuse program.

In fact, fairing recovery ship GO Ms. Tree is perhaps just a few minutes away from her third successful fairing half catch – set to occur roughly 45 minutes after Falcon 9’s 9:19 pm EST liftoff. At the same time, Falcon 9’s upper stage is coasting in low Earth orbit (LEO) and preparing to ignite one more time to circularize its orbit and send SpaceX’s third batch of 60 Starlink satellites on their way.

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.
