SpaceX Starship leaps towards Mars with picture-perfect hop debut

SpaceX’s Starship rocket has taken the biggest step towards orbit (and Mars) yet after a full-scale prototype successfully launched 150m (~500 ft) into the air and landed in one piece.

Anywhere from two to four years in the making, Starship SN5’s seemingly flawless hop debut saw the rocket carry forth a torch lit by Starhopper’s second and final flight last year. In August 2019, Starhopper completed its own 150m hop test, stunning many with the sheer oddity and unlikeliness of the achievement. Now, for the first time ever, a full-scale Starship – built with materials and methods that should translate almost 1:1 to orbital-class spaceships – has safely launched and landed.

Powered by the same methane and oxygen-fueled Raptor engine SpaceX intends to use to explore and inhabit Mars, Starship SN5’s hop debut was actually even smoother than Starhopper. Its predecessor suffered an extremely hard landing when its early Raptor engine lost power shortly before landing – a fate SN5 appears to have avoided with ease.

At this point, it’s a real possibility that SpaceX is now like the dog caught the bus – past a milestone it had not fully prepared to pass, in other words. Starship SN5’s apparent success means that SpaceX has now well and truly flight-proven the methods and materials it’s currently using to build next-generation steel rockets with. Of course, 150 meters is a drop in the bucket compared to Starship’s actual orbital destinations, but the ability to build a fully functional pressure vessel out of commodity steel and spartan facilities has always been the program’s biggest uncertainty.

With SN5 safely back on land, SpaceX can now immediately begin to work towards far more ambitious flight tests. The most notable of those tests will likely be a 20 km (~12 mi) launch followed by a bizarre skydiver-style landing attempt, second only – of course – to Starship’s first orbital launch and reentry attempts.

After weeks of attempts with SN5 alone and another seven months of work with prototypes SN1, SN3, SN4, and three smaller test tanks, Starship’s successful full-scale hop debut is simultaneously unsurprising and almost impossible to believe. Notable is the fact that even after today’s roaring success, SpaceX appears to be hard at work building a new Starship – SN8 – out of an entirely different steel alloy designed to make the rockets even sturdier than they already are.

According to NASASpaceflight.com, Starship SN8 will be the first full-scale prototype to have a functioning nose and aerodynamic control surfaces installed and will attempt the aforementioned 20 km “skydiver” recovery and landing test. SpaceX could begin stacking SN8’s components at any moment.

The fates of Starship SN5 – and outdated-alloy-sibling SN6 – is unclear but whatever they are, they are now all but guaranteed to follow on the heels of a highly successful career.

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

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.
