The first orbital spacecraft designed and built by SpaceX is set to smash a reusability record on its 20th and final International Space Station (ISS) resupply launch, hopefully ending an exceptional career with yet another noteworthy achievement.

After a rocket-related hardware issue forced a four-day delay, a flight-proven Cargo Dragon spacecraft and Falcon 9 rocket are set to lift off no earlier than (NET) 11:50 pm EST, March 6th (04:50 UTC, March 7th) on NASA’s 20th and final SpaceX Commercial Resupply Services (CRS-20) mission. Although SpaceX’s final CRS1 launch, 20th mission milestone, flight-proven Dragon, and fairly quick Falcon 9 booster turnaround are all significant and exciting in their own ways, the most noteworthy technical aspect of CRS-20 can be found in the Dragon capsule that will soon be perched atop the tip of the rocket.

Shared on March 1st alongside confirmation of a successful Falcon 9 wet dress rehearsal (WDR) and static fire at its Cape Canaveral, Florida Launch Complex 40 (LC-40) pad, SpaceX revealed that Cargo Dragon capsule C112 (C1: Dragon 1; 12: capsule #12) will be supporting CRS-20 as early as this Friday. If all goes according to plan, it will be the spacecraft’s third cargo mission to the ISS since February 2017, becoming the third orbital SpaceX vehicle to do so. Even more significantly, C112 is poised to crush Cargo Dragon’s own previous record for the shortest time between two orbital launches.

Back in June 2017, SpaceX became the first private company in history to successfully reuse an orbital-class spacecraft on its CRS-11 Cargo Dragon mission, itself the first private spacecraft in history to successfully rendezvous with the space station. Since then, all but one CRS mission has featured an orbit-proven Dragon capsule, making CRS-20 the ninth time SpaceX will attempt to launch a spacecraft into orbit for the second (or third) time.

In other words, nearly half of all of SpaceX’s NASA CRS missions have featured flight-proven spacecraft, while several have also launched with flight-proven Falcon 9 boosters. Still, while extremely impressive that SpaceX has managed to convince the risk-averse space agency to fly several dozen tons of critical hardware on flight-proven rockets and spacecraft, Cargo Dragon capsule reuse has always been a comparatively lengthy and complex process.

Back in July 2017, just a month after SpaceX’s first successful Cargo Dragon reuse, CEO Elon Musk offered some insight into the capability’s potential value.

“Musk said he expects the next Dragon reuse and all future reuses to save SpaceX nearly 50% of the cost of manufacturing an entirely new spacecraft. Musk admitted that the first refurbishment of Dragon likely ended up costing as much or more than a new vehicle, but this is to be expected for the first attempt to reuse any sort of space hardware that must survive some form of reentry heating and saltwater immersion.”

Ultimately, SpaceX has almost certainly realized Musk’s ambition of cutting the cost of orbital space station resupply missions in half (at least). Scheduled to launch on March 6th, Cargo Dragon capsule C112 last launched in December 2018, reentering Earth’s atmosphere and splashing down on January 13th, 2019. With CRS-20, the capsule could thus crush the previous record – 19 months – by more than 25%. Measured from splashdown to the capsule’s shipment to the launch pad, SpaceX may have spent less than a year refurbishing the Cargo Dragon spacecraft, likely more than a 50% improvement over all past refurbishment operations.

CRS-20 should thus mark a climactic and fitting end to Cargo Dragon 1’s nine-year spaceflight career. While bittersweet that the spacecraft and its many siblings will likely never fly again, Musk has said that Dragon 2 (Crew Dragon) – the spacecraft intended to replace it – is dramatically easier (and thus cheaper) to reuse than Dragon 1. As such, SpaceX should have no issue continuing its trend of lowering the cost of access to space after it begins space station cargo deliveries under its CRS2 NASA contract later this year.

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.
