Relativity Space has shipped both stages of its first 3D-printed Terran-1 rocket to a launch pad it recently finished constructing at Florida’s Cape Canaveral Space Force Station (CCSFS), leaving the startup just a few steps away from its first orbital launch attempt.

As Relativity CEO Tim Ellis himself noted, the company is about two years behind its initial goal of a 2020 launch debut, but it’s far from alone in that regard. Virtually all of its most direct competitors are in similar boats. Out of sheer coincidence, startups ABL Space and Firefly Space are working towards orbital launch attempts of their similarly sized RS1 and Alpha rockets – ABL for the first time and Firefly for the second time – as early as summer 2022. Now, so is Relativity.

Almost simultaneously, all three companies have announced that both stages of their Terran-1, RS1, and Alpha rockets have arrived at their respective launch sites in Florida, Alaska, and California. Firefly, who has already successfully static fired Alpha’s first and second stages, is undoubtedly in the lead, but ABL Space and Relativity are neck and neck for second.

Both of the latter startups have successfully qualified the smaller, less powerful upper stages of their RS1 and Terran-1 rockets. Both intend to conduct final booster qualification testing – including the first all-engine, full-power static fires – at their launch sites. ABL has a bit of a leg up over Relativity, as it delivered its RS1 booster to its Kodiak, Alaska launch pad months ago. Still, Relativity appears to be on a roll and delivered both stages of its unique 3D-printed Terran-1 rocket to its Cape Canaveral launch site just a few weeks apart in May and June 2022. ABL Space also suffered a major failure during its first attempted upper stage qualification, though the company rapidly recovered. At least publicly, Relativity has experienced no major stage failures while developing Terran-1.

Firefly has finished qualifying the first and second stages of its second Alpha rocket.
ABL Space has finished qualifying its first flightworthy RS1 upper stage and is closing in on its first attempted booster static fire.
Relativity has also qualified its first Terran-1 upper stage and is preparing to static fire the rocket’s booster.

Alpha, RS1, and Terran-1 are all designed to launch roughly 1.2-1.35 tons (2600-3000 lb) to low Earth orbit. All three are roughly the same size and designed to be expended after every launch. Terran-1 and RS1 are designed to launch up to 1.25 and 1.35 tons for $12 million, while Alpha is a bit more expensive at $15 million for 1.17 tons. RS1 is a largely traditional welded-aluminum rocket not unlike SpaceX’s Falcon 1, but with nine smaller booster engines instead of Falcon 1’s one. Alpha is almost entirely built out of carbon fiber composites and is powered by four slightly larger main engines.

Terran-1 has nine 3D-printed booster engines and is also made mostly of aluminum. However, Relativity’s claim to fame is 3D printing, and it says that even its very first Terran-1 rocket is 85% 3D-printed by mass and is the largest single 3D-printed object ever built. Terran-1 reportedly weighs around 9.3 tons (20,500 lb) empty.

If Terran-1’s booster qualification testing goes as smoothly as it did for the rocket’s upper stage, Relativity could be ready for its first orbital launch attempt as early as summer (Q3) 2022, just in time to join Firefly (July) and ABL (August). Relativity Space’s ultimate goal? 3D-print similar rockets on Mars.

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.”
