New information from both NASA and the US Government Accountability Office (GAO) confirm that SpaceX is currently targeting – at least very tentatively so – Crew Dragon’s first launch with astronauts aboard no earlier than November 15th, 2019.

SpaceX is currently in the midst of a complex, high-stakes anomaly investigation after its flight-proven DM-1 Crew Dragon capsule suffered a catastrophic failure on April 20th. That investigation is nowhere near full closure due to the fact that the interests of NASA and the Commercial Crew Program (CCP) are equally interwoven into the work involved. Given the potential consequences of a similar failure occurring with astronauts (public or private) aboard, NASA is unlikely to accept anything less than a no-stone-left-unturned analysis and failure resolution, including any necessary design changes to Crew Dragon, no matter how far-reaching.

As NASASpaceflight.com’s Chris Gerbhardt notes, the Crew Dragon-related dates included in the NASA Flight Planning Integration Panel (FPIP) document are extremely tentative. They’re really only there to serve as placeholders for longer-term International Space Station planning, already a necessarily uncertain endeavor. Nevertheless, NASA’s NET November 15th 2019 planning date for Crew Dragon DM-2 (the first crewed test flight) was likely okayed by SpaceX – if not provided outright by the company – before going into an official FPIP.

In other words, November 15th is probably a real target but should be treated as an absolutely-positively-no-earlier-than launch date for Crew Dragon’s first astronaut-laden mission to the ISS. Back in late March (after DM-1’s successfully completion but before the capsule’s ground failure), anonymous Russian space industry sources confirmed that NASA’s DM-2 planning date was July 25th, while also indicating that the space agency was already preparing for delays that could push DM-2 as late as November 2019.

Specifically, an anonymous Roscosmos source told Russian outlet TASS that “the [DM-2] launch of Crew Dragon is likely to be postponed to November”. Given that that delay was rumored – albeit quasi-officially – and reported on nearly a month before Crew Dragon capsule C201 catastrophically exploded during testing, it doesn’t exactly inspire confidence in a November 2019 DM-2 planning date officially released by NASA more three months later.

Crew Dragon stumbles, but optimism remains

As is often said, things were going perfectly up to the point that they weren’t. Despite 2-3 months of NASA paperwork and review-related delays, SpaceX’s first flightworthy Crew Dragon performed flawlessly during orbital rendezvous, docking, departure, and reentry to the extent that NASA and SpaceX officials were joking on-webcast about their partial disbelief. NASA’s lengthy post-mission review effectively concluded as much, although there is always room for improvement.

Due to those aforementioned DM-1 delays (roughly early January to early March), DM-2’s Crew Dragon assembly and integration was delayed in turn to preserve access in case DM-1 revealed flaws or necessary changes. Things didn’t quite go as planned, but the delayed integration has turned out to be beneficial, preserving access to most of Dragon 2’s critical subsystems without requiring major disassembly before any anomaly-related changes are implemented.

A May 2019 NASA update indicated that SpaceX’s DM-2 Crew Dragon (likely the vehicle previously assigned to the subsequent USCV-1 mission) is in the late stages of assembly. Once the anomaly investigation is complete and the DM-2 spacecraft is updated with any necessary modifications, SpaceX will likely require an additional ~4 months of work to reach flight-readiness.

Per a late-May update from CCP manager Kathy Lueders, SpaceX has effectively shifted its Crew Dragon hardware assignments over one to account for the loss of the DM-1 capsule, C201. The vehicle previously assigned to DM-2 has been reassigned to a critical in-flight abort (IFA) test, previously meant to use flight-proven C201. Per charts provided during Lueders’ presentation, SpaceX’s replacement DM-2 capsule (likely the capsule previously assigned to the following mission, Crew-1) is in a sort of holding pattern to allow for modifications that may be required after the DM-1 failure investigation concludes.

Per a previous December 2018 update from Lueders, SpaceX’s original DM-2 spacecraft (now assigned to IFA) was expected to be fully assembled, shipped to Pad 39A, and ready for launch by June 2019. Accounting for DM-1’s delays, that spacecraft could likely be ready for the abort test as early as July or August, which meshes with post-anomaly indications that IFA is now scheduled no earlier than fall (September 2019)

All things considered, a pragmatic analysis suggests that Crew Dragon‘s DM-2 launch will most likely happen no earlier than Q1 2020, although miracles (and nightmares) are certainly possible. For the time being, all that really matters to SpaceX is wrapping up the C201 failure investigation as quickly and accurately as possible. Only after the company has publicly announced the results of that investigation should any IFA or DM-2 launch dates be taken with anything less than a full shaker of salt.

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.
