SpaceX CEO Elon Musk says he will provide a public update on the development status of Starship and Super Heavy in an official presentation later this summer, possibly as soon as June 20th.

Meanwhile, SpaceX’s South Texas team have been busy at work on both Starhopper and a newer Starship, said by Musk to be the first orbit-capable prototype. In the last week, technicians have begun stacking several sections of the vehicle’s stainless steel hull, all fabricated and welded together side-by-side. On Thursday, May 9th, this progressed to the installation of the Starship’s first gently tapered nose section atop its cylindrical tank section. Likely the second- or third-to-last major stack before its aeroshell is assembled into one piece, the orbital prototype is starting to truly resemble a real Starship.

They grow up so fast…

CEO Elon Musk revealed SpaceX’s Mars colonization architecture back in September 2016 and has since provided design and development updates every 6-12 months. Between then now, Starship/Super Heavy (formerly BFR, fore-formerly ITS) has radically changed. Originally baselined with a diameter of 12 m (40 ft), an almost entirely carbon composite design, and a spaceship with bulky tripod fins/wings, SpaceX helped design, build, and test a full-scale liquid oxygen tank.

Six months after the tank was destroyed (likely intentionally) during testing, Musk announced in Sept. 2017 that ITS was now called BFR and would feature a leaner 9m (30 ft) diameter. He also revealed tentative plans to enlist BFR in a point-to-point Earth transportation scheme offering travelers access to almost anywhere on Earth in ~30 minutes. In September 2018, the design changed once more, gaining ~10m of height and three mobile tripod fins/wings/legs. Finally, just a few months after the 2018 update, Musk revealed that SpaceX was moving almost entirely away from carbon composites and would instead use stainless steel throughout BFR’s structure. BFR was also renamed to Starship/Super Heavy.

Episode 4: Revenge of the Steel

Given SpaceX’s breakneck pace of Starhopper and Starship development, it’s possible that Musk’s “probably June 20th” event is meant to correlate with a yet-unknown Starship or Starhopper milestone. Back in early January, Musk suggested that the first orbital Starship prototype could be “complete” as early as June. However, a few weeks later, Starhopper suffered a setback when its facade/nosecone toppled over and was irreparably destroyed.

Several months distant, it’s hard to actually say if that hardware loss has impacted SpaceX’s schedule much at all. Sans nose section, SpaceX instead conducted a number of wet dress rehearsals and successfully ignited Raptor and jumped the tethered Starhopper a few feet in early April, more or less right on schedule per a December 2018 Musk tweet.

At this point in time, it’s highly unlikely that the orbital Starship prototype will be truly complete just a month or two from now. Most notably, “completion” would require seven flight-ready Raptor engines, of which SpaceX is known to have only completed 3-4 in the last four months. Despite an apparent lack of Raptors for a June completion of the orbital prototype, it may actually be possible for SpaceX to complete (in a very rough sense) the main structure of the Starship.

Major progress has been made in the last few weeks and the orbital prototype is starting to look more and more like an actual Starship. Aside from finishing the vehicle’s propellant and header tanks and engine section/thrust structure, SpaceX still needs to install avionics, wiring, plumbing, cold-gas maneuvering thrusters, COPVs, access and umbilical ports and panels, an entire heat shield, its tripod wings/fins/legs, and more. At the same time, it’s unclear if SpaceX will attempt to send Starship to orbit on its own before the first Super Heavy booster prototype is complete, an even more massive undertaking ahead of the company.

For now, all we can do is wait and watch SpaceX’s gloriously bizarre steel Starship prototype continue to grow, while Starhoppper prepares for untethered hops a few thousand feet to the east. Things could be worse!

Tesla is already giving Robotaxi privileges hours after opening public app

This morning, Tesla launched the app in the Apple Store, giving iOS users the ability to download and join a waitlist in hopes of gaining access.

Tesla is already giving Robotaxi privileges to those who downloaded the app and joined its waitlist just hours after it launched in the United States.

As the Robotaxi platform has been operating in Austin for several months, Tesla is now allowing the general public to download its app and call for a driverless ride in the city.

Tesla Robotaxi makes major expansion with official public app launch

The company previously sent invitations to select media outlets and Tesla influencers, seeking initial feedback on the performance of the Robotaxi platform.

There have been positive reviews, but, as with any Beta program, some mishaps have also occurred, although none have been significant.

As of the writing of this article, the City of Austin only lists one incident involving a Tesla Robotaxi, noting it as a “Safety Concern,” but not an accident or collision.

This morning, Tesla launched the app in the Apple Store, giving iOS users the ability to download and join a waitlist in hopes of gaining access.

Tesla is already granting Robotaxi access to several of those who have downloaded the app and gotten on the waitlist early:

With the launch of the public app, we were not too sure how soon Tesla would be able to initiate bringing more riders into the Robotaxi program. The immediate admittance for some riders just hours after the launch is a big positive and is surely a sign of strength for Tesla and its Robotaxi program.

What many will look for moving forward is the expansion of the geofence, which does not seem like a problem, as Tesla has already managed to do this on three occasions. The most recent expansion has expanded the service area to approximately 190 square miles.

People will also look for evidence of fleet expansion, a concern that has been a concern for many, especially since Tesla has not been completely transparent about it. They have revealed a recent service fleet growth of 50 percent, but there has been no specific number of vehicles mentioned.

Tesla explains why Robotaxis now have safety monitors in the driver’s seat

The update to Austin’s safety monitors became a point of interest among Tesla watchers on social media.

Tesla has provided an explanation about the presence of safety monitors in the driver’s seat of its autonomous Robotaxi units.

The autonomous ride-hailing service is currently being deployed in Austin and the Bay Area, with more cities across the United States expected to gain access to the service later this year.

Safety Monitors

When Tesla launched its initial Robotaxi program in Austin, the company made headlines for operating vehicles without a human in the driver’s seat. Even with this setup, however, Tesla still had safety monitors in the passenger seat of the Robotaxis. The safety monitors, which do not interact with passengers, have been observed to report issues and other behaviors from the autonomous vehicles in real time. 

Safety monitors on the driver’s seat were also employed in the service’s Bay Area rollout, though numerous members of the EV community speculated that this was likely done to meet regulations in California. However, with the expansion of the Austin geofence, riders in Tesla’s Robotaxis observed that the safety monitors in the city have been moved to the driver’s seat as well.

Tesla’s explanation

The update to Austin’s safety monitors became a point of interest among Tesla watchers on social media. Longtime FSD tester Whole Mars Catalog, for one, speculated that the move might be due to Texas’ new regulations for autonomous vehicles, which took effect recently. Interestingly enough, the official Tesla Robotaxi account on X responded to the FSD tester, providing an explanation behind the safety monitor’s move to the driver’s seat.

“Safety monitors are only in the driver’s seat for trips that involve highway driving, as a self-imposed cautious first step toward expanding to highways,” the Tesla Robotaxi account noted.

Tesla has been extremely cautious with its autonomous driving program, particularly with the rollout of its Robotaxi service, which use Unsupervised FSD. This is quite understandable considering the negative media slant that Tesla is consistently subjected to, which could very well result in minute incidents or mistakes by Robotaxis being blown out of proportion.

Elon Musk’s The Boring Company has started recruitment efforts for the Music City Loop, an underground tunnel system designed to link downtown Nashville with Nashville International Airport. 

Tennessee Gov. Bill Lee expressed strong support for the project, describing it as a cost-free alternative to traditional mass transit systems that could ease traffic congestion in the city. Initial digging began in mid-August, with visible progress reported by September 1, as noted in a WKRN report.

Job creation and project scope

The Boring Company is currently seeking engineers, electricians, mechanics, and operations coordinators as part of its hiring drive for the Music City Loop in Nashville. Gov. Lee emphasized that unlike large-scale transit projects that typically cost billions, the tunnel system will not burden taxpayers.

“We’ve been trying to find ways, Metro Nashville has in particular, to develop transit in the city for a long time. It costs billions and billions of dollars to build out transit systems. We now have an opportunity to have a transit system that costs the taxpayers nothing,” Lee said, calling the effort the fast lane to the city’s future.

The Music City Loop aims to provide a quick and efficient link between the city center and the airport, similar to The Boring Company’s other tunnel projects like the Las Vegas Convention Center Loop. Officials have praised the company for cooperating with state permitting and regulatory requirements, suggesting that the Nashville Loop project is advancing in line with established processes.

Community reactions and concerns

While officials are optimistic, community response has been mixed. Some residents have raised concerns about the speed of approval and a lack of public discussion before construction began.

Nashville resident Taylor John cited environmental impacts and worries that the tunnel could primarily serve tourists rather than local commuters. “I have a lot of concerns, first of all, by how fast this decision was made, I don’t think there was a lot of discussion from the members of the community before this decision was made. It’s going to impact us,” the resident stated.

Others, however, see the project as an innovative leap forward. “There’s a whole untapped potential underneath our feet,” resident Nathaniel Lehrer stated. “Anything that can save time when picking up family or friends or you need to catch a flight, it’d be an awesome option to have.”
