SpaceX building almost 1500 Starlink satellites per year

Published

on

SpaceX has revealed a few key details about its burgeoning Starlink satellite internet constellation in a recent regulatory presentation, touching on overall investment, user terminal development, and its spacecraft manufacturing capabilities.

Already the single largest satellite constellation in the world by a factor of three or more, Starlink is more than 500 operational satellites strong after just nine months of launches, and the company has at least 5-8 more missions planned between now and the end of 2020. To further expand the world’s largest satellite constellation, though, SpaceX also needs to be the world’s most prolific satellite manufacturer by at least an order of magnitude.

Ever since SpaceX’s first dedicated Starlink launch in May 2019, the company has remained extremely secretive about the unprecedented satellite production infrastructure it also had to develop. Aside from a few comments by CEO Elon Musk and the occasional tidbit from regulatory documents or spaceflight conferences, very little is known and not a single photo has been released. An FCC ex parte presentation with a few specific details thus came as a surprise, revealing that SpaceX is building at least 120 Starlink satellites per month in its Redmond, Washington factory.

Based on past analysis of SpaceX’s Redmond facilities, the company has about 150,000 square feet (14,000 m^2) to work with, of which a third to half is likely dedicated to a satellite assembly line. Despite the relatively small facilities, SpaceX says it is actively building 120 satellites per month – equivalent to at least 1440 spacecraft annually. By mass, it means that SpaceX is churning out more than 30 metric tons (~69,000 lb) of satellites every single month, a figure almost certainly unprecedented in the history of satellite manufacturing.

Sustained over 12 months, that would equate to ~360 metric tons (10% heavier than a fully-fueled Falcon 9 V1.0 rocket) of satellites built every year. In short, with an extremely small (and thus efficient) base of operations, SpaceX is regularly producing a vast quantity of satellites – enough to indefinitely sustain two full Starlink launches per month. At that rate, SpaceX could fairly easily complete the Starlink constellation’s first ~4400-satellite phase in just three years.

Production capacity or efficiency would need to expand significantly for SpaceX to complete the second (~12,000 satellites) and third (~40,000 satellites) phases of the Starlink constellation, By then, though, the first phase would likely be generating substantial revenue, optimistically allowing SpaceX to self-fund future growth or at least dramatically reducing the need for fundraising.

Along those lines, the same FCC ex parte presentation included a note that “SpaceX has invested hundreds of millions of dollars in Starlink to date,” including “over $70 million developing and producing thousands of user terminals per month.” In other words, SpaceX has apparently spent less – and possibly much less – than $1 billion designing, manufacturing, and launching almost 600 satellites. For comparison, competitor OneWeb apparently spent more than $3.4 billion and filed for bankruptcy before it had launched even 100 satellites.

That exceptional efficiency will, as CEO Elon Musk has noted several times, hopefully make Starlink the first low Earth orbit (LEO) satellite internet constellation in history to not go bankrupt. The company hopes to begin rolling out a much wider Starlink beta test after the 14th v1.0 satellite launch – currently four launches away. If all goes well during that beta test, Starlink could become the first LEO internet constellation in history to begin generating significant revenue not long after.

Tesla Semi catches fire in California: what we know

Published

A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.

The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.

There were no injuries reported.

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.

However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.

The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.

The truck’s driver said that the Semi caught fire, but he did not have an explanation.

An estimated 5,000 to 7,000 semi-truck and large commercial vehicle fires occur on U.S. roadways every year.

Tesla’s ‘Emergency Drive Away’ function gets its first use in the real world

Published

Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.

A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.

“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.

Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.

Tesla constitutes the following situations as reasonable justifications for activating the feature:

  • You face an immediate threat to your life or personal safety.
  • You must leave the area immediately.
  • Exiting the vehicle is unsafe.
  • Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.

After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.

Tesla’s Cybercab battery design could make robotaxis even cheaper

Tesla built the Cybercab’s battery pack with spare room for a future switch to LFP.

Published

By

Tesla built the Cybercab’s battery pack with empty space inside it on purpose, and the reason points to a cheaper robotaxi down the road.

Robert Sumpf, Tesla’s director of mechanical design engineering for battery modules and packs, said the extra room beside and beneath the Cybercab’s modules was left there so the company can move to lithium iron phosphate cells later. “So, we protected this pack to go to an even lower energy dense chemistry as we scale and need to bring LFP into the platform,” Sumpf said in a Cybercab deep dive with Munro Live.

The Cybercab runs on Tesla’s own 4680 cells with a nickel chemistry today. LFP cells store less energy for their size, so a straight swap would cut range. The reserved space lets Tesla add more LFP cells to make up the difference. In return, Tesla would get cells that cost less, run cooler and survive more charge cycles. LFP became the most used EV battery chemistry in the world last year.

Not all of that room was planned for a chemistry change. Lars Moravy, Tesla’s Vice President of Vehicle Engineering, said part of it exists because “we didn’t need as many batteries as we thought we did.” Tesla told Sandy Munro in early 2025 that it was targeting a Cybercab pack under 50 kWh with close to 300 miles of range.

The pack also breaks from the structural design Tesla used in some Model Y and Cybertruck builds. Instead of potting hundreds of cells into one block, the Cybercab uses four separate, individually sealed modules, so a bad module can be replaced without scrapping the whole pack. Sumpf was blunt about the older approach, giving the Model Y structural battery “a grade D” because it was hard to build and nearly impossible to repair. He estimated a fully structural pack gains about 10% more cell volume, but said “the issue is the service cost.”

That cost matters more for a car that rarely sits parked. Cybercab chief engineer Eric Earley said replacing an entire pack “before half a million miles is a killer on cost,” which is why remanufacturing and serviceability were built into the design from the start.

The same Munro Live tour produced Moravy’s admission that the Cybercab line at Giga Texas is now outpacing Robotaxi deployments, along with a look at the robotaxi’s unorthodox paint process. Tesla is aiming to deliver the first Cybercabs to outside customers by the end of 2026, though Elon Musk has said the vast majority will stay owned by Tesla and run as a transport service.

Sumpf did not give a date for an LFP version, name a cell supplier or say how a chemistry change would affect range. For now, the 4680 cars keep piling up: Texas DMV records from Tuesday list 544 Cybercabs authorized for Tesla’s Robotaxi fleet, more than the 507 Model Ys on the same roster for the first time.
