After a handful of days as an impressive monolith stood along the coastal wetlands of Texas, SpaceX technicians have once again separated the nose and tail sections of the first Starship prototype to allow additional integration and assembly work to continue. The craft’s three Raptors were also removed and stored nearby, shown to be barebones facsimiles standing in for flightworthy hardware that could arrive in the next month or two.

Up next, three or four propellant tank domes – currently being assembled and welded together on-site – will likely be installed inside the steel hull of the giant Starship prototype’s aft barrel section. Known as bulkheads, the installation of those tank domes will bring SpaceX one step closer to performing hop tests of the simultaneously bizarre, confusing, and beautiful craft.

At this point in time, it appears that Starhopper is some odd combination of showmanship and actual hardware meant to test certain aspects of the first orbital Starship build, said to be complete as early as June 2019 by CEO Elon Musk. In the last week or so, SpaceX technicians attached and welded over Starhopper’s two sections – an aft barrel with legs and Raptors and a conical nose – and even did a sort of photoshoot, removing an on-site fence for a photo that Musk later shared while stating that the vehicle had “completed assembly”.

One could argue that assembly is not exactly complete if the given product has to be pulled in half to install significant new components. Regardless, the external skin, aft barrel section, and rough landing legs do appear to be more or less complete from a very basic structural perspective, although there is clearly much work still to be done if the vehicle’s tank bulkheads haven’t been installed. Aside from completing the liquid oxygen and methane tank structure, SpaceX engineers and technicians will additionally have to complete the vehicle’s aft section, a massive 9m/30ft-diameter thrust structure capable of supporting the thrust of three Raptor engines and the weight of the entire fueled rocket. After that, plumbing, avionics, sensors, attitude thrusters, and more will still need to be completed and integrated.

If Starhopper’s nose section is largely a nonfunctioning aerodynamic shroud and propellant tanks will be primarily located inside the aft section, the fuel and oxidizer capacities of the vehicle’s tanks can be roughly estimated. Assuming a 9m/30ft diameter, the aft barrel stands around 13m/43ft tall. Assuming that the upper tank dome will reach a meter or two above the steel cylinder and that the aft Raptor thrust structure is also roughly 1-2 meters deep, Starhopper would have a total tank volume around 830 m3 or almost 30,000 cubic feet (~225,000 gallons), potentially 1000 metric tons of fuel or more if fully loaded.

Perhaps less than coincidentally, SpaceX already has liquid methane and oxygen tanks on-site (one is pictured above) with more than enough capacity to meet Starhopper’s potential propellant needs. However, it’s worth noting that current plans (and permissions) only show Starhopper traveling as high as 5km on flights that will last no more than 6 minutes, and CEO Elon Musk has indicated in no uncertain terms that the prototype will remain distinctly suborbital and is primarily focused on fleshing out Starship’s vertical take-off or landing (VTOL) capabilities before SpaceX proceeds to much more aggressive tests.

While it would be safe to take his schedule with many dozens of grains of salt, Musk noted last week that the first orbit-ready Starship could be finished as early as June 2019, while he expects Starhopper tests to begin as early as February or March. Where exactly that orbital Starship and its Super Heavy booster partner will be built is now much less clear after SpaceX has reportedly canceled a berth lease and thus its plans to build a BFR factory in the Port of Los Angeles. Will SpaceX build a BFR factory in Texas or will it build the orbital Starship en plein air like its Starhopper predecessor? And Super Heavy? Where will all three conduct static fires, hops, or launches from?

Stay tuned as more details and photos continue to bubble up from beneath the surface.

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.
