SpaceX CEO Elon Musk announced via Twitter that Starhopper’s first untethered hover tests – flying as high as ~20 meters (65 ft) – could be attempted as early as Tuesday, July 16th.

SpaceX engineers and technicians have been working around the clock the last several months to prepare Starhopper for flight and – even more importantly – prepare the company’s next-gen Raptor engine to ensure it is reliable enough to risk losing the Hopper in flight. Neither task is a small challenge, with both pushing SpaceX’s workforce into new and (partially) unfamiliar territory, ranging from Starhopper’s use of steel propellant tanks to Raptor’s adoption of liquid methane and oxygen instead of the kerosene/oxygen or hydrazine SpaceX’s workforce is familiar with

Back in April 2019, SpaceX – having installed Raptor SN02 roughly two weeks prior – static fired Starhopper for the first time ever, simultaneously lifting the massive craft a few inches off the ground as it strained against its tethers. Three and a half months later, SpaceX engineers appear to have finally solved a mechanical resonance (vibration) issue that plagued all Raptors that came before SN06, forcing aborts, limiting test length, and even destroying or damaging engines beyond repair.

As previously discussed on Teslarati, Starhopper’s first true flight tests have been a long time coming. 9m (30 ft) in diameter and perhaps 25m (80 ft) tall, Starhopper is an extremely unusual and visually bizarre test article, effectively acting like a (vaguely) mobile Raptor test stand and a full-fidelity way for SpaceX’s aluminum-focused welding and fabrication crews to gain experience building a moderately functional stainless steel rocket.

Last month, there was some hope that Raptor SN05 would be capable of supporting Starhopper’s first hover tests as early as mid-to-late June, but it’s understood that the vibrational issue described above by Musk damaged the engine during one of its final acceptance tests, delaying Starhopper testing by several weeks. Had that resonance issue been solved months ago, it’s probable that Raptor SN02 could have taken Starhopper directly from its first static fires to untethered flight operations in April.

According to CEO Elon Musk, SpaceX’s Raptor manufacturing team is rapidly moving from a development-focused line to something more like mass-production. Once the design has been more thoroughly pinned down, the production ramp could max out with up to two Raptor engines completed daily, averaging out to an annual production rate of an incredible ~500 engines.

Additionally, Musk tacitly acknowledged that SpaceX’s recent development Raptors likely cost around $2M apiece, but the final mass-production cost could drop as low as $200,000 per engine, almost unfathomable for such a high-performance, cutting-edge engine.

For the time being, SpaceX will be focused on wringing out any subtler design flaws and general bugs in Raptor as the engines are gradually produced and tested at increasing volumes. This includes hop/hover tests like those Starhopper is scheduled to attempt next Tuesday, as well as even wilder ~20-km suborbital flight tests that could come once one or both of SpaceX’s “orbital” Starship prototypes are fully integrated.

Tesla lands approval for Robotaxi operation in third U.S. state

On Tuesday, Tesla officially received regulatory approval from the State of Arizona, making it the third state for the company to receive approval in.

Tesla has officially landed approval to operate its Robotaxi ride-hailing service in its third U.S. state, as it has landed a regulatory green light from the State of Arizona’s Department of Transportation.

Tesla has been working to expand to new U.S. states after launching in Texas and California earlier this year. Recently, it said it was hoping to land in Nevada, Arizona, and Florida, expanding to five new cities in those three states.

On Tuesday, Tesla officially received regulatory approval from the State of Arizona, making it the third state for the company to receive approval in:

Tesla has also been working on approvals in Nevada and Florida, and it has also had Robotaxi test mules spotted in Pennsylvania.

The interesting thing about the Arizona approval is the fact that Tesla has not received an approval for any specific city; it appears that it can operate statewide. However, early on, Tesla will likely confine its operation to just one or two cities to keep things safe and controlled.

Over the past few months, Robotaxi mules have been spotted in portions of Phoenix and surrounding cities, such as Scottsdale, as the company has been attempting to cross off all the regulatory Ts that it is confronted with as it attempts to expand the ride-hailing service.

It appears the company will be operating it similarly to how it does in Texas, which differs from its California program. In Austin, there is no Safety Monitor in the driver’s seat, unless the route requires freeway travel. In California, there is always a Safety Monitor in the driver’s seat. However, this is unconfirmed.

Earlier today, Tesla enabled its Robotaxi app to be utilized for ride-hailing for anyone using the iOS platform.

Tesla ride-hailing Safety Monitor dozes off during Bay Area ride

We won’t try to blame the camera person for the incident, because it clearly is not their fault. But it seems somewhat interesting that they did not try to wake the driver up and potentially contact Tesla immediately to alert them of the situation.

A Tesla Robotaxi Safety Monitor appeared to doze off during a ride in the California Bay Area, almost ironically proving the need for autonomous vehicles.

The instance was captured on camera and posted to Reddit in the r/sanfrancisco subreddit by u/ohmichael. They wrote that they have used Tesla’s ride-hailing service in the Bay Area in the past and had pleasant experiences.

However, this one was slightly different. They wrote:

“I took a Tesla Robotaxi in SF just over a week ago. I have used the service a few times before and it has always been great. I actually felt safer than in a regular rideshare.

This time was different. The safety driver literally fell asleep at least three times during the ride. Each time the car’s pay attention safety alert went off and the beeping is what woke him back up.

I reported it through the app to the Robotaxi support team and told them I had videos, but I never got a response.

I held off on posting anything because I wanted to give Tesla a chance to respond privately. It has been more than a week now and this feels like a serious issue for other riders too.

Has anyone else seen this happen?”

My Tesla Robotaxi “safety” driver fell asleep
byu/ohmichael insanfrancisco

The driver eventually woke up after prompts from the vehicle, but it is pretty alarming to see someone like this while they’re ultimately responsible for what happens with the ride.

We won’t try to blame the camera person for the incident, because it clearly is not their fault. But it seems somewhat interesting that they did not try to wake the driver up and potentially contact Tesla immediately to alert them of the situation.

They should have probably left the vehicle immediately.

Tesla’s ride-hailing service in the Bay Area differs from the one that is currently active in Austin, Texas, due to local regulations. In Austin, there is no Safety Monitor in the driver’s seat unless the route requires the highway.

Tesla plans to remove the Safety Monitors in Austin by the end of the year.

Tesla opens Robotaxi access to everyone — but there’s one catch

Tesla has officially opened Robotaxi access to everyone and everyone, but there is one catch: you have to have an iPhone.

Tesla’s Robotaxi service in Austin and its ride-hailing service in the Bay Area were both officially launched to the public today, giving anyone using the iOS platform the ability to simply download the app and utilize it for a ride in either of those locations.

It has been in operation for several months: it launched in Austin in late June and in the Bay Area about a month later. In Austin, there is nobody in the driver’s seat unless the route takes you on the freeway.

In the Bay Area, there is someone in the driver’s seat at all times.

The platform was initially launched to those who were specifically invited to Austin to try it out.

Tesla confirms Robotaxi is heading to five new cities in the U.S.

Slowly, Tesla launched the platform to more people, hoping to expand the number of rides and get more valuable data on its performance in both regions to help local regulatory agencies relax some of the constraints that were placed on it.

Additionally, Tesla had its own in-house restrictions, like the presence of Safety Monitors in the vehicles. However, CEO Elon Musk has maintained that these monitors were present for safety reasons specifically, but revealed the plan was to remove them by the end of the year.

Now, Tesla is opening up Robotaxi to anyone who wants to try it, as many people reported today that they were able to access the app and immediately fetch a ride if they were in the area.

We also confirmed it ourselves, as it was shown that we could grab a ride in the Bay Area if we wanted to:

The launch of a more public Robotaxi network that allows anyone to access it seems to be a serious move of confidence by Tesla, as it is no longer confining the service to influencers who are handpicked by the company.

In the coming weeks, we expect Tesla to then rid these vehicles of the Safety Monitors as Musk predicted. If it can come through on that by the end of the year, the six-month period where Tesla went from launching Robotaxi to enabling driverless rides is incredibly impressive.
