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 Full Self-Driving becomes main pillar of new Referral Program

Published

on

Credit: Tesla

Tesla Full Self-Driving is now the centerpiece of the company’s newly revised Referral Program, which launched on October 29.

Instead of referring people to purchase vehicles and the referrer receiving $250 in Tesla Credit, the new program now incentivizes Full Self-Driving subscriptions.

If a Tesla owner is on an FSD trial and uses a referral code to subscribe to Full Self-Driving, the person whose Referral Link was used will receive one month of FSD (Supervised). Their code can be utilized 12 times per year, with January 1 marking the reset date.

Realistically, this means that if your Referral Code is used by 12 Tesla owners on an FSD trial, you will receive a full year of FSD for free.

The previous program made it pretty difficult to get referrals; buying a vehicle is obviously a much larger financial strain than subscribing to Full Self-Driving for a month.

Of course, the previous Referral Program also offered a tangible benefit: $250 in credits you could use on Service, Supercharging, or anything in the Tesla Shop. It truly could pay for someone’s travel for a year. It recently bought me a new backpack and a T-shirt.

However, this new program is much more attainable for those who do not have a massive online presence of a slew of friends in the Tesla community who will use the code and max out subscriptions for vehicle purchases.

The Full Self-Driving suite will now be the keystone of the Referral Program, which makes it more inclusive and more fun for everyone with an awesome benefit.

It also gives the impression that Tesla is truly focused on FSD subscriptions, something that saw a tremendous increase in volume in Q3, as 75 percent of deliveries for the quarter came with an FSD subscription attached.

Full Self-Driving data is so instrumental to the suite’s improvement that this kind of program benefits Tesla as much as it does the consumer.

Tesla made napping in a Robotaxi easier with its latest update

Tesla’s quiet mode reaches Model Y Robotaxis, blacking out the screen for riders wanting rest.

Tesla’s quiet mode, the setting that blacks out the screen for riders who want to rest, has moved beyond the Cybercab. A video posted Thursday by Spencer (@scotsrule08) shows the feature running in a Model Y Robotaxi on a night ride that appears to be in Dallas.

The rider taps a small crescent moon icon in the bottom right corner of the map screen. The map, media player, app shortcuts and Grok prompt disappear, leaving a dark display with “Arriving soon,” the destination and a line reading “Tap display to exit quiet mode.” Controls a passenger may still need, including Pull Over, cabin temperature, volume and Support, stay visible. One tap anywhere brings the full map back.

Quiet mode first showed up in the Cybercab last week, which Teslarati reported alongside a new rear camera view. Tesla has been trimming cabin noise in other ways too. On October 25, Spencer reported that Robotaxi turn signals now chime for the first four blinks and then go silent. Tesla has not published release notes for either change.

Elon Musk has been pitching this use for more than a decade. In October 2014, he said that “maybe five or six years from now I think we’ll be able to achieve true autonomous driving where you could literally get in the car, go to sleep and wake up at your destination,”

By 2017 he was setting a higher bar. Speaking at TED, Musk said the hard part was not making self-driving work 99.9 percent of the time, “because, like, if a car crashes one in a thousand times, then you’re probably still not going to be comfortable falling asleep. You shouldn’t be, certainly.”

Owners asked for something similar in their own cars. In December 2019, a Tesla owner requested a Nap Mode that would keep the climate running and wake the occupant with an alarm, and Musk answered “Ok,” as Teslarati covered at the time.

The line returned when the Cybercab was unveiled at the We, Robot event in October 2024. “We’ll move from supervised Full Self-Driving to unsupervised Full Self-Driving, where you can fall asleep and wake up at your destination,” Musk said. On Tesla’s first quarter earnings call in April 2025, he called it the deciding measure: “The acid test is, can you go to sleep in your car and wake up in your destination and I’m confident that will be available in many cities in the US by the end of this year,”

Tesla has run driverless Model Y rides in Dallas and Houston since April, so a passenger dozing off on the way home is now a realistic use of the button. Tesla is also offering new riders a free first trip in both cities, according to an in-app screen shared by tracker Ethan McKanna, and said on its third quarter call that Cybercab rides would launch in Dallas next month.

FCC green lights SpaceX’s move to a showdown with Verizon and AT&T

The FCC advanced plans opening 482 MHz to satellite phone service, boosting SpaceX’s Starlink Mobile.

Published

A hand holds a smartphone displaying the Starlink Mobile app interface showing a strong “Connected – Direct to Cell” signal, with a Starlink satellite beaming connectivity signals down to Earth from orbit. The background features the planet’s night side glowing with city lights against the curve of the atmosphere, set above a scenic twilight landscape.

The Federal Communications Commission voted Thursday to move forward with a proposal that would open an additional 482 MHz of spectrum to satellite service beamed directly to ordinary phones, a step that could widen the road for SpaceX’s Starlink Mobile to compete with the country’s largest wireless carriers.

The commission adopted the notice of proposed rulemaking at its October open meeting in Washington, Reuters reported. The proposal would raise the number of bands eligible for Supplemental Coverage from Space from five to 13, according to the FCC fact sheet. Commissioners also advanced a companion item proposing an auction of 25 MHz in the 1675 to 1695 MHz and 2020 to 2025 MHz bands, which could be used for terrestrial service, direct to device service or both.

Thursday’s vote does not hand any spectrum to SpaceX. It opens a public comment period, and final rules will come later. Under the draft, comments would be due 60 days after the notice is published in the Federal Register. The FCC had not released the adopted text at the time of writing, so it is not yet clear whether any bands were changed before the vote.

That question is where the fight now moves. AT&T, Verizon and T-Mobile, through industry group CTIA, asked the FCC to drop the 2.5 GHz and 3.45 GHz bands, which make up 290 MHz of the 482 MHz on the table, as Teslarati reported ahead of the vote. T-Mobile argued satellite interference could wipe out up to 96% of a cell site’s uplink coverage area. SpaceX asked the commission to go the other way and add the 902 to 928 MHz band.

The rule change that matters most to SpaceX may be a structural one. Today, a satellite operator must lease spectrum from every carrier holding co-channel licenses across an entire region such as the contiguous United States. The proposal would replace that with a certification that the operator has coexistence agreements covering only the areas it plans to serve, or that it holds the terrestrial licenses itself.

SpaceX has spent this year building that second path. It bought EchoStar’s AWS-4 and H-block licenses in a deal worth roughly $17 billion, and earlier this month agreed to acquire Grain Management’s nationwide 800 MHz portfolio, which the company said would pave the way for Starlink to become a major US mobile carrier. The FCC approved SpaceX’s purchase of three unused AWS-3 licenses from Tristar on October 21, and cleared its plan for 15,000 next generation direct to cell satellites on October 6.

The regulator has not always sided with SpaceX. In April, the FCC dismissed a SpaceX petition seeking access to Mobile Satellite Service spectrum held by incumbents, and it rejected 2.5 GHz for satellite coverage when it first adopted the framework in 2024.

The carriers are also building their own defenses. In May, the three companies agreed in principle to form a joint venture pooling spectrum for satellite service, and T-Mobile remains SpaceX’s US launch partner for Starlink Mobile even as it leads the push to keep satellites out of 2.5 GHz. SpaceX President Gwynne Shotwell has said service on SpaceX’s own airwaves is targeted for early 2028.
