SpaceX tweaks Starlink Gen2 plans to add Falcon 9 launch option

Published

on

SpaceX says it has revised plans for its next-generation Starlink Gen2 constellation to allow the upgraded satellites to launch on its workhorse Falcon 9 rocket in addition to Starship, a new and unproven vehicle.

Set to be the largest and most powerful rocket ever flown when it eventually debuts, SpaceX’s two-stage Starship launch vehicle is also intended to be fully reusable, theoretically slashing the cost of launching payloads into and beyond Earth orbit. Most importantly, SpaceX says that even in its fully-reusable configuration, Starship should be capable of launching up to 150 tons (~330,000 lb) to low Earth orbit (LEO) – nearly a magnitude more than Falcon 9. However, once said to be on track to debut as early as mid-2021 to early 2022, it’s no longer clear if Starship will be ready for regular Starlink launches anytime soon.

In August 2021, SpaceX failed a major Starlink Gen2 revision with the FCC that started the company along the path that led to now. That revision revealed plans to dramatically increase the size and capabilities of each Gen2 satellite, boosting their maximum throughput from about 50 gigabits per second (Gbps) to ~150 Gbps. Just as importantly, SpaceX’s August 2021 modification made it clear that the company would prefer to launch the entire constellation with Starship, although it included an alternative constellation design that would lend itself better to Falcon 9 launches.

In January 2022, SpaceX chose to solely pursue the constellation optimized for Starship, strongly indicating that the company believed the rocket would be ready to support Starlink launches in the near future – or at least around the same time the constellation receives its Gen2 FCC license. With the benefit of technical Starlink Gen2 satellite details and renders provided by SpaceX and CEO Elon Musk in Q2 2022, a single Starship Gen2 launch using the current satellite and rocket designs and carrying 54 satellites could potentially deploy around 7-8 times more usable bandwidth than a Falcon 9 with Starlink V1.5, meaning that Starship could achieve similar deployment results with just a few launches per year.

In theory, that makes it at least somewhat easier for Starship to make a major impact even as SpaceX works to ramp up the brand-new rocket’s launch cadence, a task that has almost always taken several years.

However, additional changes made to its Starlink Gen2 FCC license application in August 2022 suggest that SpaceX has at least partially tempered that all-in bet on Starship. The most important modification: developing a different Starlink Gen2 satellite variant that will be optimized to fit inside Falcon 9’s much smaller payload fairing. According to SpaceX, despite the seemingly major form-factor changes required to make Gen2 fit, Starship and Falcon 9-optimized satellites will still be “technically identical.”

The implication is that the satellites launched on Falcon 9 will still offer the same performance as those launched on Starship, albeit in a different form factor. Nonetheless, the only thing SpaceX guarantees in the document is that the Falcon 9-launched Gen2 satellites won’t be more powerful than those launched on Starship, presumably preserving the applicability of existing analysis in the current Starlink Gen2 application. It’s thus possible that Falcon 9-optimized Starlink Gen2 satellites will have to sacrifice some of their performance relative to the unconstrained Starship-optimized variant.

With a usable diameter of 4.6 meters (~15 ft), Falcon 9’s payload fairing is about 50% narrower than the payload bay present on early Starship prototypes. Without a major redesign, Starlink Gen2 satellites optimized for Falcon 9 will likely need to sit vertically inside the fairing, the standard version of which stands 6.7 meters (~22 ft) tall before its conical tip begins curving inwards. Weighing about 1.25 tons (~2750 lb) and measuring 7 meters (~23 ft) long, Starlink Gen2’s design may only need a few moderate tweaks to fit on Falcon 9, but they’ll have to be stacked vertically instead of horizontally. Falcon 9’s established performance of roughly 16.5 tons (payload adapter included) to LEO means that the rocket will be limited to around 12 or 13 Gen2 satellites per launch, however, making the task somewhat easier.

If SpaceX can squeeze that many Starlink Gen2 satellites inside of Falcon 9’s existing reusable fairing, it could still boost the efficiency (total bandwidth per launch) of each Starlink mission by ~50% relative to the same rocket carrying 50-60 Starlink V1.5 satellites. It’s no surprise, then, that SpaceX appears to be doing everything it can to begin launching Starlink Gen2 as quickly as possible, whether or not Starship is ready to help.

Tesla Phone? Not quite, but close: analyst

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.”

Tesla will continue to roll out the v14 Lite suite more widely in the coming weeks, the company said.
