SpaceX’s Starship comes to life for the first time in lead-up to launch debut

For the first time ever, SpaceX has pressurized Starship Mk1’s building-sized propellant tanks, a critical test that culminated in the rocket prototype essentially taking its first ‘breaths’.

An anthropomorphization sometimes used to describe the venting launch vehicles often exhibit while during and after fueling, Starship Mk1’s so-called ‘breaths’ occurred around 5:59 pm CST (23:59 UTC). Those first vents came after roughly an hour or two spent performing several different pressurization cycles, observable due to the fact that Starship’s stainless steel tanks visibly smoothed out as pressure increased.

Due to the typical distances Starship is viewed from and the nature of the mirror-finished stainless steel SpaceX has chosen to build the next-generation launch vehicle out of, the exterior of Starship prototypes can produce a reflection that looks bumpy and disjointed. This has lead many a layperson to incorrectly assume that SpaceX’s Starship prototypes are thus shoddily built. In reality, viewed from afar, the tiniest hint of surface heterogeneity on a mirror can dramatically change what is reflected on its surface.

Even at the thinness of Starship Mk1’s liquid oxygen and methane tanks, stainless steel is still extremely strong, but pressurizing the vehicle’s tanks can clearly counteract a significant portion of the slight imperfections in their curvature.

Starship Mk1 produced a jet of gas longer than its own width, visible from a webcam located a dozen or so miles away.

Although it’s now clear that SpaceX did in fact perform some kind of pressurization test with Starship Mk1, it remains to be seen what exactly the nature of that testing was. First and foremost, SpaceX did establish significant roadblocks almost six hours before testing began, and company workers vacated the launch site several hours before visible Starship pressurization and venting. Fairly soon after that vent, workers returned to the pad and may or may not have been present during additional (but more subdued) venting activity.

Most importantly, November 18th’s testing featured a sum total of zero visible activity at SpaceX’s nearby flare stack, a mechanism used to burn waste methane gas to prevent dangerous buildups at worksites (or launch pads). This almost certainly means that methane (gaseous or liquid) played no role in pressurizing Starship Mk1’s propellant tanks.

Altogether, that likely means that Monday’s proof test was not a wet dress rehearsal (WDR), a term used to describe the process of testing a launch vehicle by fully fueling it and performing a countdown identical to a real launch – but without engine ignition or liftoff. Instead, SpaceX likely began the day’s testing by pressurizing Starship several times with a neutral gas like nitrogen or helium, while gaseous oxygen is also a possibility but is significantly less likely. Simply by using pressure sensors on Starship and knowing the volume of gas that is being loaded, SpaceX could likely determine whether the prototype has any leaks.

The major vent around 6 pm local time could have simply been Starship venting that pressurant gas, which would explain why there was just a single large, observable vent. When dealing with cryogenic liquid propellant, those supercool liquids gradually heat up, causing a portion to boil and turn into gas, gas that launch vehicles then vent intermittently to prevent overpressure events (i.e. explosions). Starship Mk1 only visibly vented once, although there may have also been some additional venting even after technicians returned to the launch site (another sign that the pressurant was neither toxic or combustible).

Oddly, shortly after SpaceX workers returned to the launch pad, they appeared to begin spraying down Starship Mk1 with a large volume of water or foam, producing clouds of mist as large as Starship itself. This came as a total surprise and why it’s being done is entirely unclear. Possible explanations include simply rinsing Starship (but why and why now?), checking its tanks for leaks, applying industrial quantities of WD40 (used to protect stainless steel from rust), or maybe even testing how Starship stands up to ice (extremely unlikely as it would need to be filled with a cryogenic liquid to be cold enough).

Perhaps the morning light will bring some answers. All things considered, as long as the mysterious spraying is not indicative of any serious issues or concerns with Starship Mk1, SpaceX may now be ready to put the prototype through a true propellant loading test, potentially filling its tanks with as much as 1200 metric tons (2.65 million pounds) of liquid oxygen and methane. If or when Starship passes that test, it’s next trial will be the very first triple-Raptor-engine static fire test. For now, we wait.

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.
