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

Published

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 reveals it is using AI to make factories more sustainable: here’s how

Tesla is using AI in its Gigafactory Nevada factory to improve HVAC efficiency.

Tesla has revealed in its Extended Impact Report for 2024 that it is using Artificial Intelligence (AI) to enable its factories to be more sustainable. One example it used was its achievement of managing “the majority of the HVAC infrastructure at Gigafactory Nevada is now AI-controlled” last year.

In a commitment to becoming more efficient and making its production as eco-friendly as possible, Tesla has been working for years to find solutions to reduce energy consumption in its factories.

For example, in 2023, Tesla implemented optimization controls in the plastics and paint shops located at Gigafactory Texas, which increased the efficiency of natural gas consumption. Tesla plans to phase out natural gas use across its factories eventually, but for now, it prioritizes work to reduce emissions from that energy source specifically.

It also uses Hygrometric Control Logic for Air Handling Units at Giafactory Berlin, resulting in 17,000 MWh in energy savings each year. At Gigafactory Nevada, Tesla saves 9.5 GWh of energy through the use of N-Methylpyrrolidone refineries when extracting critical raw material.

Perhaps the most interesting way Tesla is conserving energy is through the use of AI at Gigafactory Nevada, as it describes its use of AI to reduce energy demand:

“In 2023, AI Control for HVAC was expanded from Nevada and Texas to now include our Berlin-Brandenburg and Fremont factories. AI Control policy enables HVAC systems within each factory to work together to process sensor data, model factory dynamics, and apply control actions that safely minimize the energy required to support production. In 2024, this system achieved two milestones: the majority of HVAC infrastructure at Gigafactory Nevada is now AI-controlled, reducing fan and thermal energy demand; and the AI algorithm was extended to manage entire chiller plants, creating a closed-loop control system that optimizes both chilled water consumption and the energy required for its generation, all while maintaining factory conditions.”

Tesla utilizes AI Control “primarily on systems that heat or cool critical factory production spaces and equipment.” AI Control communicates with the preexisting standard control logic of each system, and any issues can be resolved by quickly reverting back to standard control. There were none in 2024.

Tesla says that it is utilizing AI to drive impact at its factories, and it has proven to be a valuable tool in reducing energy consumption at one of its facilities.

Tesla analysts believe Musk and Trump feud will pass

Tesla CEO Elon Musk and U.S. President Donald Trump’s feud shall pass, several bulls say.

Tesla analysts are breaking down the current feud between CEO Elon Musk and U.S. President Donald Trump, as the two continue to disagree on the “Big Beautiful Bill” and its impact on the country’s national debt.

Musk, who headed the Department of Government Efficiency (DOGE) under the Trump Administration, left his post in May. Soon thereafter, he and President Trump entered a very public and verbal disagreement, where things turned sour. They reconciled to an extent, and things seemed to be in the past.

However, the second disagreement between the two started on Monday, as Musk continued to push back on the “Big Beautiful Bill” that the Trump administration is attempting to sign into law. It would, by Musk’s estimation, increase spending and reverse the work DOGE did to trim the deficit.

President Trump has hinted that DOGE could be “the monster” that “eats Elon,” threatening to end the subsidies that SpaceX and Tesla receive. Musk has not been opposed to ending government subsidies for companies, including his own, as long as they are all abolished.

Despite this contentious back-and-forth between the two, analysts are sharing their opinions now, and a few of the more bullish Tesla observers are convinced that this feud will pass, Trump and Musk will resolve their differences as they have before, and things will return to normal.

ARK Invest’s Cathie Wood said this morning that the feud between Musk and Trump is another example of “this too shall pass:”

Additionally, Wedbush’s Dan Ives, in a note to investors this morning, said that the situation “will settle:”

“We believe this situation will settle and at the end of the day Musk needs Trump and Trump needs Musk given the AI Arms Race going on between the US and China. The jabs between Musk and Trump will continue as the Budget rolls through Congress but Tesla investors want Musk to focus on driving Tesla and stop this political angle…which has turned into a life of its own in a roller coaster ride since the November elections.”

Tesla scrambled its executives around following the exit of CEO Elon Musk’s sidekick last week, Omead Afshar. Afshar was relieved of his duties as Head of Sales for both North America and Europe.

Bloomberg is reporting that Musk is now overseeing both regions for sales, according to sources familiar with the matter. Afshar left the company last week, likely due to slow sales in both markets, ending a seven-year term with the electric automaker.

Tesla’s Omead Afshar, known as Elon Musk’s right-hand man, leaves company: reports

Afshar was promoted to the role late last year as Musk was becoming more involved in the road to the White House with President Donald Trump.

Afshar, whose LinkedIn account stated he was working within the “Office of the CEO,” was known as Musk’s right-hand man for years.

Additionally, Tom Zhu, currently the Senior Vice President of Automotive at Tesla, will oversee sales in Asia, according to the report.

It is a scramble by Tesla to get the company’s proven executives over the pain points the automaker has found halfway through the year. Sales are looking to be close to the 1.8 million vehicles the company delivered in both of the past two years.

Tesla is pivoting to pay more attention to the struggling automotive sales that it has felt over the past six months. Although it is still performing well and is the best-selling EV maker by a long way, it is struggling to find growth despite redesigning its vehicles and launching new tech and improvements within them.

The company is also looking to focus more on its deployment of autonomous tech, especially as it recently launched its Robotaxi platform in Austin just over a week ago.

However, while this is the long-term catalyst for Tesla, sales still need some work, and it appears the company’s strategy is to put its biggest guns on its biggest problems.
