Relativity’s first 3D-printed rocket aims to debut a new rocket fuel
Relativity can almost taste the vacuum of space. A substantial amount of work remains, but the startup continues to defy expectations with its relentless and methodical push towards the first orbital launch of a 3D-printed rocket.
Founded in 2015, the Los Angeles-based aerospace company has taken its few years of obligatory delays in stride while pursuing a 2020 debut for its (relatively) small Terran 1 rocket. In a world with dozens of serious rocket startups, missing one’s initial launch target is practically a rite of passage – the path to orbit is never as straight and bump-free as the highway on-ramps that are often promised in pitch decks. Relativity Space, however, is no average rocket startup.
Save for SpaceX, which operates in a league of its own, no other private rocket startup has come close to matching the $1.3 billion Relativity has raised to develop Terran 1 and the much larger Terran R. More importantly, in a recent interview with Aviation Week, CEO Tim Ellis (a former Blue Origin engineer) revealed that the company could be “weeks away” from the first launch of Terran 1, a rocket that is 85% 3D-printed by mass and could simultaneously debut a new kind of rocket fuel.
Once fully assembled, Terran 1 – weighing around 9.3 tons (~20,500 lb) empty and measuring 33.5 meters (110 ft) tall – will be the largest metal 3D-printed object in the history of the technology. From that perspective, it’s hardly surprising that Relativity Space is a few years behind schedule. In fact, it’s odd that the startup isn’t more delayed, and it’s even more impressive that Terran 1’s first launch campaign has gone as smoothly as it has.
Slow, Smooth and Fast
Terran 1 Flight 1’s booster stage and upper stage both arrived at the company’s leased Cape Canaveral Space Force Station LC-16 pad sometime in May 2022. Terran 1’s first stage came directly from the California factory. The second stage (S2), however, first shipped to a Mississippi test stand a few months prior and, on its first try, completed a full-duration multi-minute static fire test known as a mission duty cycle (MDC) – about as close as it’s possible to get to replicating orbital upper stage operations on the ground. The flawless MDC was preceded by a number of simpler precursor tests, of course, but the rocket performed more or less as expected throughout the entire qualification program. If Terran’s second stage ignites again, it’ll be at the edge of space.
Since June, the critical path for Terran 1’s launch debut has thus been qualifying the first finished Terran booster. Rather than modify its Mississippi test facilities, Relativity decided to temporarily modify its heavily upgraded LC-16 pad to support booster qualification testing. Thanks to the heroic work of a shockingly small team of five people, the pad was ready to kick off testing as soon as the Terran 1 booster arrived in Florida. Even more surprisingly, senior manager Lorenzo Locante says that LC-16 – practically a new pad after Relativity’s extensive modifications – has “performed perfectly” during every booster qualification test attempted thus far.
That testing has included pneumatic proofing (an ambient-temperature gas pressure test), possible cryogenic proof tests, multiple rounds of propellant loading, preignition testing of its nine Aeon engines, and multiple spin-start tests (the last step before static fire testing) with the same engines. Given that LC-16 and Terran 1 must handle cryogenic oxidizer (liquid oxygen) and cryogenic fuel (liquid methane), which can easily create a flammable and bomb-like mixture of gases from even the smallest of leaks, it’s difficult to emphasize just how difficult it is to ensure that a complex launch pad and rocket perform nominally during their first joint testing.


According to engineers onsite during a private Teslarati tour of Relativity’s Florida launch facilities, Terran 1 S1’s next goal is to fully ignite its Aeon engines. After one or more successful static fires, the booster will be integrated with the upper stage and nosecone for a final full-duration static fire test that will also double as a full wet dress rehearsal (WDR). Testing the fully-integrated Terran 1 rocket will only be possible once LC-16’s full strongback and launch mount (also known as a transporter/erector) is completed, but that final piece of the puzzle should be ready any day now.
De Terra Ad Astra
The coming weeks will likely be some of the company’s riskiest and most difficult yet. If the rocket and LC-16 continue to operate as smoothly as they have been, however, there’s a nonzero chance that Terran 1 could beat the likes of SpaceX (Starship), Blue Origin (New Glenn), and the United Launch Alliance (Vulcan Centaur) to the punch to become the first methane and oxygen-fueled rocket in history to attempt an orbital launch.*
*While SpaceX’s Starship is technically the first large-scale suborbital methalox rocket to attempt (and complete) a launch, there has never been an orbital methalox launch attempt.
Capable of carrying up to 1.25 tons (~2750 lb) to low Earth orbit for as little as $12 million, Terran 1 also has a shot at becoming the first new privately-developed 1-ton-class rocket of any kind to successfully reach orbit. On that front, though, Relativity is in a neck-and-neck race with Firefly Aerospace and ABL Space, both of which intend to launch similarly-sized rockets at some point in the next few months. It’s never been less clear who will cross the finish line first but one would be hard-pressed to count Relativity out.

Tesla officially launches Robotaxi service with no driver
Tesla launches its driverless Robotaxi in Austin, marking the first time the company has offered its ride-hailing service anywhere in the world.

Tesla has officially launched its Robotaxi service platform with no driver in Austin, Texas. This is the first time Tesla has allowed driverless Robotaxis to pick up members of the public and take them around via the ride-sharing service the company has been developing for several years.
Teslarati had a first-hand look at the launch of the Robotaxi service in Austin, as we are part of the Early Access group, which is a limited group of people that will be able to hail a driverless Model Y in the geofenced area in Texas.
The Robotaxi platform is currently geofenced in a small portion of South Austin. It is roughly thirty minutes from end to end, and Tesla’s strategy is prioritizing safety through a number of safeguards that are implemented in this early program.
There is a fixed price of just $4.20 for any ride, regardless of duration, at this time. This will not always be the case, however. When a wider customer base is allowed to hail Robotaxis, ride fares will vary on things like travel distance, length of trip, and potentially time of day.
Here’s one of the first videos of Tesla Robotaxi ride

The first rides kicked off at around 2 p.m. local time in Austin. They are confined to the back row of the Model Y, while a Tesla safety monitor sits in the passenger seat. Passengers will have their personal media and streaming settings available to them as the car will sync with their driver profiles.
Rides are requested through a Robotaxi addition on the regular Tesla iOS app:

The safety monitor is only there to ensure things go smoothly with each ride. They do not have pedals or a steering wheel on their side. The car is doing everything during these Robotaxi rides.
The big takeaway from Robotaxi’s launch is that Tesla will begin generating additional revenue through this new stream. As concerns over demand and annual growth rate continue to take focus from doubters, Tesla’s continuous rollout of the Robotaxi fleet will expand potential revenue opportunities, potentially creating billions upon trillions of dollars in value.
This is something Tesla permabulls like Cathie Wood of ARK Invest and Dan Ives of Wedbush have talked about for years: the launch of a driverless Robotaxi fleet that generates new income streams for Tesla.

First Look at Tesla’s Robotaxi App: features, design, and more
Tesla is using a Robotaxi section of its normal smartphone application to enable access to driverless vehicles roaming around Austin.

Tesla has officially launched the Robotaxi platform to a limited number of people, giving them the ability to ask for a ride from a driverless Model Y in Austin, Texas. But how do you hail a ride?
Through the Tesla Robotaxi app, which officially launched on June 22 as the company initiated the first rides for non-employees, people can request rides from driverless cars that are traveling around Austin. Teslarati gained access to the app as we are members of the Early Access Rider program.
There are only a very limited number of vehicles operating within the fleet currently, as Tesla has said the number is between 10 and 20 vehicles.
Tesla is using a Robotaxi section of its iOS smartphone app for the launch, confirming what the company said prior to the program’s maiden voyage: there would not be a separate app for the Robotaxi.
First Look at the Robotaxi App
The Tesla Robotaxi app, similar to the official Tesla App, features a simple interface that should be familiar to anyone who has used a ride-sharing app in the past. Downloading the app brings users to a sign-in page, which features a Tesla Model Y Robotaxi as a header image. Users can then log in or create an account to access the service.

A Clean, Simple UI
Upon logging in, users are presented with a clean user interface that allows them to select a destination and pickup point. Upon booking, users are provided with a real-time update on when their Robotaxi will arrive. Users could also select some settings for their upcoming ride, such as their preferred temperature in the cabin.
Smart Suggestions
If there is one evident thing about Tesla’s Robotaxi App, it is the fact that it is smart and designed to make driverless ride sharing services feel as normal as possible. While waiting for their ride, customers are presented with a number of tips that should help them understand their robotaxi better.
These include tips on how to use the Model Y’s door handles, as well as information about the vehicle’s light signals. The app also includes smart suggestions on destinations that riders can visit using their Robotaxi. These include cafes, restaurants, parks, shopping centers, and other pertinent locations.
Cybercab Theme
Another thing that is evident with the Robotaxi App is its Cybercab-inspired color theme. This is evident from the login page, which already features the golden hues of the dedicated two-seater autonomous car. The golden Cybercab color theme is used to great effect inside the app itself as well.
No Tips, at Least for Now
As observed by Tesla owner-enthusiast @BLKMDL3, Tesla is not accepting anything more than the service’s flat $4.20 rate per ride for now. If customers wish to leave a tip for the service, they would be presented with a page featuring Tesla’s hedgehog mascot saying “Just Kidding.”
Tips will likely be an option in the future, but for this stage of the Robotaxi rollout, it appears that the service really will follow a flat rate system.

Watch Tesla’s first driverless public Robotaxi rides in Texas
Tesla’s first driverless Robotaxi rides for non-employees are starting with the first drives beginning today.

Tesla has finally launched its Robotaxi platform to members of the public for the first time in Austin, Texas.
The Tesla Robotaxi platform is a driverless ride-hailing service that will enable people to use their cars for passive income as they will ride around, find riders, and drive them to their destinations in exchange for money. For right now, Tesla is using company vehicles, the Model Y specifically, and has opened up rides to a small number of people who are a part of the Early Access Program.
Teslarati is a member of the Early Access Program, as we were invited to Austin for the launch. We have gained access to Tesla’s new Robotaxi app, which lies within the main Tesla iOS app, and we are able to use the Robotaxi fleet during the Early Access Program.
The first rides are already occurring as Tesla launched the platform at around noon local time in Austin on Sunday:

The video shows that Tesla’s initial Robotaxi rides are being quite cautious. Currently, the Robotaxis can only travel within a geofenced portion of Austin. This area will eventually be expanded.
For the time being, Tesla is keeping a safety rider in the vehicles with occupants, but they do not take up the driver’s seat. Instead, they are sitting in the passenger’s seat. This is simply a safety precaution that Tesla is using to keep Early Access riders safe, although there are ways riders can alert Tesla of any issues.
In the initial communication Tesla sent to members of the Early Access Rider program, the company said the Cabin Camera would be deactivated for the duration of their rides, but can be used if the rider needs support. Additionally, the in-cabin microphone will be deactivated, but can also be used to get in contact with support if there are any issues during the ride.
We have seen a variety of different Robotaxis rolling around Austin for the past several weeks. The company has been testing the vehicles in a very limited way for the time being, and it only has between 15 and 20 Robotaxis in the city for the launch. This number will slowly grow over time.
