SpaceX board member says Starlink prototype satellites “are working wonderfully”
Speaking in a Satellite Innovation 2018 keynote, long-time SpaceX investor and board member Steve Jurvetson made a quiet but significant comment about the company’s Starlink satellite constellation efforts, stating that the first two prototype spacecraft – currently in orbit – “are working wonderfully.”
Standing in contrast to recent speculation that SpaceX’s Starlink project had experienced major failures with on-orbit hardware, Jurvetson may be a biased source but still has a major vested interest in SpaceX’s long-term success – supporting billions dumped into a satellite constellation with no real returns in sight would serve to seriously harm his significant investments in the company.
He would say that? Maybe, but @dfjsteve Jurvetson, early @SpaceX & @planet investor, told Satellite Innovation conference Oct 10, regarding SpaceX's two Starlink test sats launched in February: pic.twitter.com/WHzJlPUEPA

Perhaps the most trustworthy source of SpaceX information outside of the company itself, Jurvetson expressed considerable confidence in SpaceX’s Starlink achievements thus far.
“I personally think SpaceX is in the lead [with Ku- and Ka-band phased arrays that could make (global LEO satellite broadband) possible] … Tintin 1 and 2 [are working wonderfully].” – Steve Jurvetson, Satellite Innovation 2018
Previously discussed on Teslarati, SpaceX’s growing experience with phased array antennas is undoubtedly a boon for the company’s proposed Starlink internet constellation, just one of several companies actively pursuing the increasingly competitive low Earth orbit (LEO) satellite broadband market. Fundamentally, phased array antennas will eventually take over nearly all multipurpose orbital communications thanks to the sheer simplicity and potential technical superiority of the technology.
Phased array antennas get their name from the fact that they have no moving parts – rather than moving a physical dish or angling dedicated ‘beams’, phased arrays actively use signal interference to very precisely shape, direct, and regulate line-of-sight communications beams. Currently quite immature, the draw of the technology is the sheer simplicity and reliability of antennas that require no moving parts, eliminating a major mode of failure and the inherent physical limitations of current antenna tech. Without something like phased arrays, LEO communications satellites would struggle to accurately and reliably track ground stations and gateways while traveling multiple kilometers per second.

- LEO communications satellites like Iridium’s NEXT constellation feature totally flat panels of phased array antennas, capable of forming beams digitally. (Harris)
Large communications satellites in geostationary orbit do not face this problem. Thanks to their inherently fixed positions over ground targets (hence “geostationary“), designers and manufacturers have learned to quite literally mold each satellite’s on-orbit antennas to explicitly prioritize certain areas on the ground. This process tends to involve a prior determination of markets where demand for satellite communications is or will be highest, while also avoiding wasted coverage over areas with no need for it. However, once the antenna is launched, its beams are almost completely permanent. If markets change, the satellite simply cannot adapt.
Phased arrays, on the other hand, can almost entirely change where their many beams are directed, how much bandwidth is dedicated to certain locations, and all while accurately tracking moving targets with very few limitations. As a result, satellites with phased array antennas are sort of the communications jacks of all trades, capable of offering high-bandwidth connectivity to stationary user terminals, large ground stations, and moving vehicles simultaneously from with the same antenna array.

If SpaceX can perfect this, they will be the only company in the world to have done so on-orbit, while other satellite operators like Iridium have managed to build and launch low-bandwidth phased arrays but have yet to attempt to do so with the bands optimal for broadband internet or at a scale that might work for constellations of hundreds or even thousands of satellites. If Jurvetson is to be believed, SpaceX’s first foray into dedicated communications satellites and specialized hardware design and manufacturing has been a major success.
Even if the orbits of Tintin A and B do suggest that some difficulties were had with at least one satellite’s electric propulsion thrusters, it’s obvious that the experience and data derived from testing the vast majority of each satellite’s non-propulsion-related systems were invaluable and well worth the effort. Another group of prototypes will likely be launched according to Elon Musk, but that’s simply how SpaceX develops complex systems – build, launch, learn, and repeat.

For years, there have been images and videos across social media platforms that have reminded me of when I was a 15-year-old kid teased by “Xbox 720” videos on YouTube. These videos are of the supposed “Tesla Phone” that Elon Musk was secretly developing in between leading Tesla with its electric cars and SpaceX with its reusable rockets.

Although Musk has put those rumors to bed several times, it was never completely out of the realm that he could get involved in cell phones in some capacity. Think outside the box and more macro-level, though. Instead of reinventing the computer, Musk reinvented connectivity by developing Starlink with SpaceX.
It could be something similar, TD Cowen analyst Gregory Williams said in a note last week, where he hinted SpaceX could be gathering some steam to acquire T-Mobile.
Williams said it would be the “clear choice” for SpaceX if it decided to go through with a network acquisition. He also suggested AT&T.
The move would be possible through selling more of its own stock, which would help SpaceX raise the money to purchase T-Mobile, which would cost roughly $300 billion. It could be one of the moves SpaceX makes post-IPO in terms of an acquisition: it already acquired Cursor AI for $60 billion.
Other analysts, like Dan Ives of Wedbush, believe SpaceX and Tesla will eventually merge into one anyway, and that conglomeration could come as soon as this year, some have said.
The implications of SpaceX purchasing T-Mobile are massive. A combined entity would create a truly ubiquitous network: T-Mobile’s terrestrial 5G towers and Starlink’s growing constellation of Direct-to-Cell satellites. This would essentially eliminate dead zones across the U.S. and potentially globally.
SpaceX would instantly become a full-scale facilities-based carrier with satellite differentiation; a huge advantage. This would pressure AT&T and Verizon heavily.
There are also concerns like a potential reduction in long-term competition, and of course, a deal of that size would face intense scrutiny from government agencies.
The strategic fit is compelling due to the existing Starlink–T-Mobile partnership and complementary technologies (space + terrestrial). It could create a dominant integrated communications player. However, the regulatory, financial, and execution hurdles are enormous — this remains highly speculative with no indication SpaceX is actively pursuing it right now.
Tesla revealed a major new Cybercab detail in a guide it released for First Responders, showing new territory in its beliefs and intentions for the ride-hailing-focused vehicle that entered production in April.
The First Responders Guide is released to give fire departments, paramedics, and other emergency personnel the proper guidance on what to do in the event of an accident, entrapment, or other situation that would require immediate attention.
On one of the pages of the First Responders Guide, Tesla revealed a stark detail about the Cybercab, which could help personnel enter the vehicle more easily in case of an emergency.
Tesla Cybercab has one important piece that AI4 cars might need for FSD
It shows Tesla has no intention of releasing any Cybercab units that were initially proposed for ride-hailing services for the general public with any manual controls, meaning a steering wheel or pedals:
“A Cybercab equipped with steering wheel, brake pedal, and an acceleration pedal is typically an engineering or test vehicle, and operates at SAE Level 2 autonomy. Cybercab is not typically equipped with a steering wheel or acceleration and brake pedals.”

This is a major development for those who continue to believe Tesla planned to release the Cybercab with any sort of manual controls so that passengers could take over if needed. However, when Tesla started manufacturing production versions of the Cybercab in Giga Texas earlier this year, they were spotted without a steering wheel or pedals.
It essentially confirms the company has no intentions of bringing manual controls to the car’s production versions. Some have argued that the likelihood of Tesla having something
There still are some Cybercab units out there with a steering wheel and pedals, and as Tesla said, these cars are engineering or test vehicles, which have Safety Monitors on board to help the car out of a precarious situation or emergency.
Tesla released the Full Self-Driving v14 ‘Lite’ suite to owners of Hardware 3 or AI3 vehicles today, adding several new features to the vehicles that were once believed to be capable of unsupervised self-driving.
Now, Tesla has released this modified suite to older Tesla vehicles, adding plenty of new features and capabilities.
Here are the full release notes for the suite:
- Distilled the intelligence from HW4 V14 into HW3. This allows HW3 to directly learn how to handle scenarios using HW4 V14 as a guide. This process unlocks the improvements that have been made to HW4 including Reinforcement Learning (RL) and offline models for HW3.
- Improved both proactive and reactive responsiveness across a wide variety of categories including navigation handling, merges and forks, pedestrian interactions, traffic lights, and vehicle cut-in scenarios.
- Improved general comfort in nominal scenarios through fewer false slowdowns, smoother steering and more consistent lane centering.
- Introduced parking, unparking, and reversing capabilities.
- Added Arrival Options for you to select where FSD should park: in a Parking Lot, on the Street, in a Driveway, or at the Curbside.
- Speed Profiles are now available at all times, to further customize driving style preference.
These improvements, according to Tesla’s Head of AI, Ashok Elluswamy, help distill the driving behavior from AI4’s v14 series into both the camera and compute configurations of AI3.
Tesla Full Self-Driving v14 ‘Lite’ for older cars finally gets released
He added:
“It includes destination options and speed profiles on city roads, but more importantly significantly improved safety. We hope you’ll enjoy it, once the build ships wide.”
FSD v14 Lite is now rolling out to AI3 early-access customers. Based on the feedback, will rollout to more customers over the next few weeks.
