SpaceX to livestream private BFR Moon mission “in high-def VR” with Starlink satellites

Published

on

Following a detailed update to SpaceX’s BFR plans and the first privately contracted mission to the Moon, CEO Elon Musk has tweeted that the company intends to stream the entire six-day journey in “high def VR”, a plan that would demand unprecedented communications capabilities between the Moon and the Earth.

Musk further confirmed that “Starlink should be active by [2023]”, suggesting – at a minimum – that the SpaceX-built and SpaceX-launched internet satellite constellation will have reached what is known as ‘initial operating capability’, pegged for Starlink at roughly 800 satellites launched.

No small task

To give some rough context for what Musk wants, streaming in high-enough quality for a good virtual reality (VR) experience on a deep space voyage around the Moon will demand a sea of bandwidth that’s difficult to find even on the surface of Earth, let alone in space. A 2017 estimate pegged the bandwidth requirements for 4K VR streaming around 300 megabits per second (Mbps), while a solution more fitting for five years of iterative improvement between now and 2023 might demand almost a magnitude greater bandwidth (~3000+ Mbps).

For context, the average American internet connection hovers around 15-20 Mbps while the average 4K YouTube video takes about 25 Mbps to stream, meaning that BFR’s communications link between the ~390,000 km (240,000 mi) Earth-Moon gap would need to be anywhere from 10 to more than 100 times faster than typical Earthly connectivity. While NASA has already completed a successful tech demonstration of laser communications from the Moon to the Earth, maxing out at a rather impressive ~620 Mbps in 2013, that one-off test concluded years ago, and there simply is no infrastructure available to achieve the sort of capabilities SpaceX will need to stream a lunar voyage in VR.

Starlink to the rescue

The only possible way SpaceX could accomplish this sort of technical feat is by having their own high-bandwidth satellite constellation at least partially operational, needs that mesh reasonably well SpaceX’s public planning schedule for their Starlink constellation. Speaking in late-2017, SpaceX VP of Satellite Government Affairs Patricia Cooper laid out a timeline that would see ~800 satellites launches sometime in the early 2020s, followed later by the remaining ~3600 spacecraft in the Phase 1 constellation. Those launches would take place between 2019 and 2024.

Since then, Musk has indirectly hinted that Starlink’s schedule has slipped or stretched 6-12 months, unsurprising for such a massive technical task at hand. This still leaves a fair amount of time for some sort of initial operational capability to be realized, even if it is little more than the skeleton necessary for Musk’s high-def VR-streaming ambitions. Although the tweet response that triggered it was deleted, Musk confirmed in the comments of his original tweet that Starlink would be the relay network of choice – having an Earth network already installed would certainly minimize the need for global ground stations to receive a BFR spaceship’s continuous lunar downlink.

Evidenced by previous comments from Musk and NASA execs expressing interest in developing a commercial communications relay between Earth and Mars, the thought is at least there that the Starlink satellite bus may sooner or later be called upon to serve as deep space communications relays throughout the solar system, beginning with the Moon and Mars.

It’s possible that those distinct space environments would necessitate changes to the spacecraft’s hardware and software, but the fundamental goal of mass-producing Starlink satellites at an unprecedented scale and cost means that a few off-the-shelf satellites could plausibly be placed in relay positions under the assumption that they will die faster than those in Earth orbit. At just a few hundred kilograms apiece, Falcon 9 would have no problems launching a handful to the Moon or elsewhere, and they could potentially be included as copassengers on BFR launches, acting as a sort of a la carte communications relay for the spaceship.

Time will tell, but SpaceX fans certainly have an incredible amount of things to look forward too from the last 48 hours alone, regardless of whether the #dearMoon BFR mission’s 2023 launch target slips (spoiler: it probably will).

Tesla Cybercab uses a unique strategy for picking up the right rider

Published

Tesla Cybercab is using a unique strategy for picking up the correct rider, which is a crucial part of ride-hailing to ensure people end up in the right place and are charged the correct price.

Cybercab will utilize an RGB strip in its front light bar that will illuminate in a variety of different colors to mark itself.

This identifying mark will also appear in the Robotaxi app, giving riders in the same location a notable distinction in an effort to avoid any confusion regarding who should get in each vehicle.

Other ride-hailing services use similar strategies: Lyft and Uber rides are recognizable through driver identity, vehicle type and color, as well as license plate. Waymo will display the rider’s initials on top of the vehicle, letting them know that the specific vehicle for them has arrived.

Tesla’s strategy is unique and interesting, but there are some flaws. Cybercab’s main purpose is aimed toward being an autonomous ride for all, including those who have disabilities like being blind or even color blind.

Tesla will likely have something in the pipeline for those who cannot see colors or have limited vision. There will definitely be multiple ways to identify which vehicle is the one that “you” specifically ordered.

Cybercab is set to start giving public rides next Thursday, September 3, in Austin, as it announced a dedicated event last week and invited many members of the Tesla community.

Tesla ends in-house wrap service that always seemed like a short-term program

Published

Tesla has said goodbye to one customization option for its vehicles: the wrap service it launched several years ago.

After launching an in-house wrap service in August 2020 for the first time in China. In the U.S., it launched in October 2023. Tesla continued to expand the program and adjust it with better pricing and fewer options for the Cybertruck.

By December 2023, it was giving owners of the Model 3, Model Y, and the Cybertruck the opportunity to give their vehicle a fresh look with a vinyl wrap.

Tesla revamps in-house vinyl wrap service with better pricing

It was only available in five locations: Costa Mesa, Oceanside, Santa Clara, West Covina, all in California, and Seattle, Washington.

However, Tesla made some big adjustments to its shop, and the wrap service is officially gone:

Wraps are very popular across the Tesla lineup, especially since the company offers relatively few colors. Many choose to wrap their Teslas with interesting colors, patterns, or even finishes, turning their cars from glossy to satin or matte.

However, Tesla’s wrap service was so limited geographically that it never really had a chance to get off the ground or compete with local shops. Every area in the United States is now overflowing with detailing shops, mobile detailers, and other automotive specialists, many of whom perform wrap services.

Tesla’s service was confined to the Pacific time zone and only spanned across two states. It was never going to be something Tesla was a major competitor in, nor was it going to disrupt the wrapping industry. Now that the program has ended, it seems pretty ideal to believe it was always going to be a short-term thing.

Along with the wrap service, Tesla removed several other products, but nothing too crazy. The Model 3 Door Pocket and Cupholder Liners, the Model S 19″ Magnetite Wheel and Winter Tire Package, Model X/Y Ski/Snowboard Carrier for Hitch Rack, Tesla’s Electric Summer Party Tee, and the Electric Summer Tee were the other items the company totally eliminated from its online shop.

Tesla Robotaxi fleet gets a brain upgrade ahead of Cybercab launch event

Tesla’s Robotaxi service now runs longer hours nationwide as its unsupervised fleet quietly grows larger.

Published

Tesla’s Robotaxi service just got easier to catch, with the company’s official Robotaxi account noting that rides are now available from 6 a.m. to 10 p.m., seven days a week, across its operating footprint. The account also said its unsupervised fleet is “a lot bigger” than before, though without specifics. The bigger change is what Tesla says upgraded intelligence in vehicle distribution and routing is what’s actually cutting wait times, not a new Full Self-Driving version.

While Tesla did not name the team behind the upgrade, the language points to its AI and fleet software group rather than the driving stack itself. Vehicle distribution and routing in Robotaxi has functioned mostly as a dispatch problem with the software deciding which idle car goes to which rider, and how far it has to travel to get there. “Upgraded intelligence” suggests a smarter version of that dispatch logic, likely using demand forecasting to position idle cars near where riders are about to request them rather than reacting once a request comes in. Tesla’s AI division has built similar prediction systems for other parts of the business, including the neural networks that power FSD itself, so applying that same approach to fleet logistics would be a natural extension rather than a new discipline for the team.

Tesla is also about a week away from a separate robotaxi milestone. The company plans to launch Cybercab, its purpose built two seat robotaxi with no steering wheel or pedals, in Austin on September 3. Cybercab has been giving employees rides on public and private roads for weeks, and the September event is expected to fold those vehicles into the existing Robotaxi fleet within days of the launch.


Austin previously ran Robotaxi from 6 a.m. to 2 a.m. as of last September, a schedule set before the service expanded into Dallas, Houston, Miami, Tampa, Orlando and the Bay Area. Wednesday’s post did not specify whether that extended overnight window still applies in Austin specifically or whether 6 a.m. to 10 p.m. is now the standard across every market. Tesla’s post, visible on its official Robotaxi account, framed the change simply as fewer riders waiting around for a car.

Whether the wider hours hold once Cybercab enters the fleet next week is the next thing worth watching. Tesla has tended to expand Robotaxi in increments, first geofence, then hours, then fleet size, and each step so far has arrived without much advance notice.
