SpaceX has at long last transported its fifth full-scale Starship prototype to a nearby launch pad, kicking off a week of busy pre-test preparations while the sixth rocket is already nipping at its heels.

Starship SN5’s move to the pad ends the longest gap between full-scale prototype testing since Starship Mk1 was destroyed in November 2019, a partially-expected failure that began a more than three-month period of infrastructure upgrades. The first upgraded Starship (SN1) rolled to the pad on February 25th, followed by SN3 on March 29th and SN4 on April 23rd, indicative of a fairly consistent monthly cadence of Starship production (and destruction).

Almost exactly two months after its predecessor headed from the factory to SpaceX’s Boca Chica, Texas launch facilities, Starship SN5 has taken its place on a brand new launch mount. The cause of that month-long delay is fairly simple. When Starship SN4 exploded on May 29th, it damaged the existing launch mount and some additional ground support equipment (GSE), forcing SpaceX to scrap the destroyed mount and build a new one from scratch. In a matter of weeks, SpaceX’s crack team of pad engineers and technicians have done exactly that.

While, judging from several sets of canceled road closure days, the new mount wasn’t built quite as quickly as someone high up in SpaceX would have hoped, the speed of the recovery from SN4’s destructive demise is still extremely impressive. For full-scale operations, SpaceX needs a strong metal structure capable of providing a Starship prototype the propellant, power, and communications links it needs to perform tests, as well as standing up to the weight of a full-loaded Starship (>1000 metric tons) and preventing the rocket from flying away during static Raptor engine tests. Additionally, the launch mount will eventually need to survive the fury of one and even three Raptor engines once Starships graduated to flight testing.

As of June 3rd, the replacement launch mount was partially-completed steel skeleton.

Barely two weeks later, SpaceX had flipped that skeleton, installed it on the actual launch mount table, finished all structural work, installed a conical frame to enable hydraulic ram testing to simulate Raptor engine thrust, and outfitted the mount with a wide variety of complex plumbing, wiring, and fixtures. The current design is about as simple as it can get but is still relatively complicated, with a wide range of systems that must work perfectly together throughout an equally wide range of temperatures and other stressful conditions.

Starship SN5’s installation on that replacement mount serves as a final confirmation that the new structure is more or less complete. Now SpaceX will be faced with the different challenges of christening the new launch mount and ensuring that it’s functioning as planned at the same time as Starship SN5 is attempting to do the same thing. The company also appears to have taken the previous launch mount’s demise as an opportunity to implement some minor design changes, all of which will also need to be tested and verified.

Delays are quite likely but Starship SN5 is currently scheduled to kick off its first test campaign as early as June 29th. SpaceX will likely begin with an ambient pressure test to check for leaks, followed by a cryogenic proof test with liquid nitrogen to confirm that SN5 performs as expected while subjected to the ultra-cold temperatures its liquid methane and oxygen propellant will be kept at. SN5 would then move into wet dress rehearsals (WDR) with live propellant and one or several static fires with a single Raptor engine. Finally, if that complex series of tests goes a little bit better than it did with SN4, Starship SN5 will become the first full-scale prototype to attempt controlled flight, hopping to at least 150m (~500 ft).

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.

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.
