Update: On March 15th, SpaceX got within milliseconds of Starship serial number 11’s (SN11) first Raptor engine test but suffered an abort just before full ignition, briefly leaving the rocket on fire.

Around 12:26 pm CDT, after an otherwise nominal static fire flow, Starship SN11 momentarily ignited one or two of its three Raptor engines’ preburners, referring to a central component that burns cryogenic liquid propellant into gas that’s ready for combustion. As with all preburner tests, intentional or otherwise, the end result looked a bit like a weak static fire and produced a small but visible amount of flame and thrust. Unlike intentional preburner tests, the static fire abort seemingly ignited something hidden inside Starship SN11’s and appeared to burn for at least another 30-40 seconds.

Starship SN8 intentionally performed a preburner test representative of SN11’s abort back in October 2020.

Raptor has proven itself to be an extremely durable engine, up to and including surviving visible onboard fires during actual Starship flight tests. Nevertheless, depending on the source of SN11’s post-abort fire and what it may or may not have burned or damaged, it’s no surprise that SpaceX ended testing for the day instead of quickly trying again, which it’s done several times prior. If the fire was largely harmless, SpaceX has already distributed notices suggesting a second attempt could happen as early as 6am to 12pm CDT (UTC-5) on Tuesday, March 16th. If more time is needed, SpaceX has the rest of the week to conduct any necessary repairs or swap out SN11’s Raptor engines.

Public documents show that SpaceX has plans to static fire and launch its latest Starship prototype within a two-day period that could begin later today.

SpaceX shipped Starship SN11 from its Boca Chica, Texas rocket factory to test and launch facilities a mile down the road on March 8th, less than five days after Starship SN10 exploded minutes after touchdown. The very next day, SpaceX completed ambient-temperature proof testing, filling Starship with benign nitrogen gas to check for leaks and verify system health. Two days after that, Starship SN11 appeared to complete a several-hour cryogenic proof test – swapping nitrogen gas for its supercool liquid form – without issue.

Despite the seemingly successful ‘cryo proof,’ something prevented a subsequent static fire test planned on March 12th before any attempt could be made, delaying the next attempt until after the approaching weekend. An agreement between SpaceX, Cameron County, and the state of Texas currently prevents road closures (and thus rocket testing) on weekends falling between Labor Day and Memorial Day, rules meant to preserve some level of public access to Boca Chica Beach.

As a result, unless SpaceX is already ready to launch (it has waivers for three such weekend closures for launch attempts), the company has to wait until Monday even if a minor issue fixable in hours or a day or so scrubs Friday test plans. While inconvenient, it’s worth noting that the existence of that public beach and the strong regulations that protect its public domain is likely one of the only reasons the general public can still get as close as they can to SpaceX’s Boca Chica ‘Starbase’.

For whatever reason, that road closure agreement does still mean that SpaceX will (in theory) be able to test and launch any day of the week from May 31st to September 6th, save for a few holidays, effectively boosting the number of opportunities by 40% for those 14 weeks. Until then, SpaceX is doing everything it can to take full advantage of the five days a week it is allowed to test Starship prototypes. N

Notably, although Starships SN8 and SN9 both hit a few weeks of technical and regulatory snags while preparing for their high-altitude launch attempts, SpaceX has been gradually speeding up that process over time. Starship SN10, the first prototype of its kind to land in one piece, took just 33 days to go from pad arrival to liftoff and spent just 8 days between its first static fire and launch attempts. The same feats took Starship SN8 77 and 50 days, respectively, with SN9 splitting the difference at 43 days from transport to liftoff and 28 days between its first static fire and launch attempts.

Road closure requests, a safety warning for residents, and a Temporary Flight Restriction (TFR) filed with the FAA all suggest that SpaceX’s current plan is to attempt Starship SN11’s first triple-Raptor static fire between 6am and 12pm CDT on Monday, March 15th. If that test goes almost perfectly, SpaceX wants to turn the rocket around for a 10 km (6.2 mi) launch attempt on Tuesday, March 16th – the very next day. Given the past performance of high-altitude Starship prototypes, that target is decidedly ambitious and likely to incur delays, but it still reveals the true scope of SpaceX’s goals even at this early stage of development.

If Starship SN11 does manage to launch within a few days of its first static fire attempt, SpaceX would still crush SN10’s 33-day record by a factor of three. Stay tuned for updates on Monday’s possible Starship static fire and rapid Tuesday turnaround attempt

Tesla Robotaxi vs. New York Taxi: Why the Yellow Cab has a lot to lose

Tesla Robotaxi could spell the beginning of the end of the New York City yellow cab.

Published

on

Tesla appears to be on its way into the Big Apple, and a traditional Yellow Cab in New York City might be a thing of the past in the near future.

As Tesla continues to put an immense focus on the rollout of its Robotaxi platform, it is evident that driverless ride-hailing modes of transportation could truly be the way that many choose to get around. This is especially prevalent in cities like New York, where many people do not own cars. Instead, they choose to walk to hail a cab.

Tesla Robotaxi is headed to New York City, but one thing is in its way

But the limited number of medallions available for taxi drivers in New York City, as well as several other points of emphasis, seem to show the future is here and yellow cabs might soon be a thing of the past.

Instead of working tirelessly to pay off the debt from medallions, entrepreneurs could soon just buy a Tesla and have it work autonomously in New York City. Tesla executives have mentioned figures as high as $50,000 per year in terms of passive income from Robotaxi operation.

That is just the tip of the iceberg, and Robotaxi presents not only one but at least five distinct advantages over the traditional cab platform. With Tesla starting to seek employees to operate Robotaxi rides in New York, according to recent job postings, New York City cabs should prepare for the disruption Tesla could potentially cause.

Lower Operational Costs and Cheaper Fares

Uber and Lyft have already undercut the costs of New York City taxis, but Robotaxi is starting to undercut even those ride-sharing programs in Austin, Texas.

In terms of how much cheaper Robotaxi will be than cabs, it is an exponential measurement over time. Robotaxi will not require salaries, benefits, or tips, and the cost of Robotaxi could end up being just a fraction of what the same ride would cost in a cab.

This feeds right back into medallion expenses and union wages: even buying a Tesla in the next few years that has the capability to operate as a Robotaxi will be a fraction of what medallions cost, which is sometimes $200,000.

Availability and Scalability

Cabs are available at all hours of the day, but at certain times, they are less available.

Robotaxis can technically operate without breaks, other than charging. Tesla has an immense focus on scaling its Robotaxi platform anyway, and once it is available for the public to use in their personal cars, Model Ys and Cybercabs could be roaming the streets of the five boroughs with more reliability and lower wait times than traditional cabs could ever offer.

This is an issue that is even more relevant in smaller cities or less congested portions of New York.

Safer and More Efficient Rides

Tesla’s Full Self-Driving technology has reported recent safety figures that are ten times less likely to be involved in an accident than a human. Tesla releases a Safety Report for each quarter that proves its safety against human drivers.

As Full Self-Driving continues to advance, it will get better. Riders who want a stable and safe ride could seek Robotaxi instead of going with a human driver. This is something that we’ll likely see more of in the future as sentiment on autonomous driving grows.

Trust in autonomous vehicles has increased substantially over the past ten years. In 2015, surveys showed that trust in autonomous vehicles was low, with only 23 percent of Americans showing that they’d ride in a driverless car.

In 2021, another study performed that asked the same question showed 57 percent of adults would try an autonomous car for their travel.

Seamless App Integration and User Experience

Taxis are not always the most entertaining to ride in, and sometimes they are even more difficult to get a ride in. Robotaxi has already shown to be an incredibly user-friendly experience, with riders being able to choose what temperature the cabin is and what music they want to listen to in the cabin.

The addition of a rear screen also allows riders to choose from a selection of games or YouTube videos in the car.

Hailing a vehicle was basically resolved with the use of Uber and Lyft. Robotaxi is just as good, if not better, from an app standpoint, especially as the in-car climate is able to be adjusted from the Robotaxi app.

Music from one Robotaxi will continue to play in your next one, too. It’s a small luxury, but it’s a feature that is an improvement over a traditional taxi.

The Push for Sustainability by New York City

New York is pushing for a city-owned fleet of all-electric vehicles by 2027.

Its green initiatives, including the Green Rides Initiative, have pushed the city’s rideshare trips to be conducted by either zero-emission or wheelchair accessible vehicles by 2030.

The focus by consumers to use green or zero-emission vehicles could also steer right into the direction of Tesla Robotaxi, as none of the vehicles in the Robotaxi fleet will be anything but all-electric Teslas.

Carbon neutrality is a goal of the City and its residents. Moving forward, we could see these programs start to put immense pressure on the yellow cab, which could eventually be a thing of the past.

Tesla plans to use Unreal Engine for driver visualization with crazy upgrade

This could change the way Driver Visualization looks for Tesla owners.

Tesla looks to be planning a major upgrade to its driver visualization for Autopilot with a crazy upgrade from its current version.

Tesla’s driver visualization appears on the center screen and shows the vehicle, its surroundings, and, when it is operating on Autopilot or Full Self-Driving, shows the route of travel.

It has improved over the years, and even includes things like pedestrians, pets, and the shapes of other vehicles. It also helps with manual driving because it can be a good representation of your surroundings when trying to change lanes or merge in traffic.

However, it appears Tesla is planning a pretty substantial upgrade with the

Coding found in the 2025.20 firmware by Tesla hacker greentheonly showed the company is planning to utilize Unreal Engine for Autopilot visualization. He said the one Tesla currently uses is “godot-based.”

Unreal Engine is a 3D computer graphics game engine that was developed by Epic Games, the developer of the popular third-party shooter game Fortnite. It was first released back in 1998, and the most recent version is Unreal Engine 5. The sixth version is in development, and it could be out in 2027 or 2028.

However, Tesla could use it for a more realistic representation of vehicle surroundings. It would undoubtedly improve driver visualization, creating a smoother and freer-flowing depiction of what is outside of the car.

SpaceX is rolling out a new feature to Starlink that could be a lifesaver in some instances, but more of a luxury for others.

Starlink is the satellite internet service that Elon Musk’s company SpaceX launched several years ago. It has been adopted by many people at their homes, many airlines on their planes, and many maritime companies on their ships.

It has been a great way for customers to relieve themselves of the contracts and hidden fees of traditional internet service providers.

Now, Starlink is rolling out a new service feature on its units called “Standby Mode,” which is part of Pause Mode. The company notified customers of the change in an email:

“We’re reaching out to you to let you know the Pause feature on your plan has been updated. Pause now includes Standby Mode, which comes with unlimited low-speed data for $5.00 per month, perfect for backup connectivity and emergency use. These updates will take effect in 30 days. All of your other plan features remain the same. You are able to cancel your service at any time for no charge.”

SpaceX did not define how fast these “low speeds” will be. However, there are people who have tested the Standby Mode, and they reported speeds of about 500 kilobytes per second.

The mode is ideal for people who might deal with internet or power outages, but still need to have some sort of internet access.

It could also be used as a backup for people who want to stay with their ISP, but would like to have some sort of alternative in case of an outage for any reason.
