SpaceX board member says Starlink prototype satellites “are working wonderfully”

Published

on

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.

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.

 

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.

Tesla flexed the new features of the Model Y L with a dedicated media event at the company’s Diner on Santa Monica Boulevard in Los Angeles.

The Model Y L is the extended-wheelbase version of the all-electric crossover, which has been voted the best-selling car in the world on three occasions. The vehicle is already rolling off production lines at Gigafactory Texas, and first deliveries are slated to take place later this year.

Tesla brings Model Y L ‘Launch Series’ to the U.S. at $61,990

Teslarati was invited to the event, but due to some scheduling conflicts, we could not make it to Los Angeles. Instead, we will have our hands on a media unit sometime in August, so we’ll be able to spend some more extended time with the Model Y L.

However, plenty of those who made it to LA shared some cool features that set the Model Y L apart from the Model Y.

Multi-Row Climate Control

Tesla fitted the Model Y L with full climate control on all three rows on the front screen. It can be adjusted by selecting which row you’d like to modify on the right-hand side of the touch screen:

Better Rear Window Visibility

One of the strangest things about the Model Y, especially the Juniper iteration, is the rear window has extremely limited visibility when looking into the rearview mirror.

Tesla has improved upon this with the Model Y L:

PowerShare will be included

Model Y L will come with PowerShare in North America, with an 11.5kW output to your home. Tesla said it would require Powerwall 3 for operation.

Wireless Charging Pad

There has been some speculation that Tesla would upgrade the wireless charging pads in the United States, but this is not the case.

Tesla owner fixes common feature complaint with crafty DIY retrofit

Tesla confirmed that it does not come with the cooled pads as the Y L in China does. This is because North America has not adopted Qi charging yet.

Thermal Management Improvements

These improvements in the Model Y L were seen with thermal management:

  • Up to 15% faster cabin cooling
  • +23% thermal efficiency gained in hot weather, 7 miles of real-world range gained
  • 8x more solar energy reflection off of glass roof
  • 30% reduction in solar energy entering the cabin

Demand

Tesla said the Model Y L is almost sold out in the U.S. It comes with

Tesla CEO Elon Musk denies ridiculous Gigafactory Shanghai rumor

Tesla CEO Elon Musk took to his social media platform X on Thursday night to deny a ridiculous rumor regarding the sale of the company’s Chinese vehicle production plant, Gigafactory Shanghai.

On Thursday, the Wall Street Journal, citing sources familiar with the matter, claimed in a scathing new report that Tesla was exploring a potential sale of the entire China business in an effort to help bolster a potential merger between SpaceX and Tesla.

Musk immediately denied the rumor not once but twice, initially calling it “fake news,” and then calling it “absurdly fake news” in a separate post just a few moments later:

The original poster of the Wall Street Journal article that Musk saw deleted the initial post sharing the headline and the rumored sale of Tesla’s China business.

The report seemed absolutely and unequivocally false to begin with; Tesla’s business in China is among the most important pieces of the company’s business. Not only does the factory supply vehicles for the domestic market, but also for various other markets in Asia and Europe.

China is also one of the largest automotive markets in the world, and Tesla has performed well there despite the robust competition.

The speculation regarding a Tesla and SpaceX merger has started to gain steam this year as the space exploration company went public just a month ago. There has been speculation that Musk will bridge all of his companies under one “umbrella company,” and analysts believe this could happen before the end of the decade.

This is the latest iteration of Musk’s very evident war on mainstream media. Reports regarding any of Musk’s companies are quick to get the dreaded “false” or “fake news” response from the CEO when they are unfounded.

Tesla AI boss reveals how big Optimus is going to get

Tesla’s Optimus chief corrected himself on X, confirming a staggering 10 million robot production target.

Tesla’s Optimus program has a new number attached to it, after Ashok Elluswamy, the executive who has run the humanoid robot program since June 2025, posted a three word correction on X Thursday, “Correction, 10 million robots.”

The line clarifies the long term annual capacity Tesla is building toward its planned second Optimus production line at Gigafactory Texas, a figure Musk has cited repeatedly since last year’s shareholder meeting.

The scale is worth noting, because ten million robots a year would mean Tesla building more units annually than most countries sell in new cars. Tesla has framed this as a second line, not the first. The buildout is happening in two phases: a roughly one million unit per year line inside Tesla’s Fremont factory, installed on the floor space vacated when Model S and Model X production ended earlier this year, and a much larger dedicated facility under construction at Giga Texas that broke ground on its first steel structure in May. That Texas facility is the one Elluswamy’s correction refers to, and is expected to reach volume production sometime in 2027.

Tesla Optimus project fires up as Musk sees production line progress

Elluswamy took over Optimus from Milan Kovac last summer and has spent the months since talking up the program’s trajectory. Elon Musk has also floated the ten million figure at Tesla’s 2025 shareholder meeting.

Ending Model S and Model X production to make room for the first Optimus line was one of the more consequential manufacturing decisions in the company’s recent history, retiring two flagship vehicles in favor of a robot that has yet to enter mass production. Musk has previously estimated per unit production costs at $20,000 to $25,000 once Tesla reaches a million units a year, though he hasn’t said what that cost looks like at ten times the volume.
