Geostationary satellite communications startup Astranis has decided to move its first operational satellite launch from a SpaceX Falcon 9 to a Falcon Heavy, effectively securing the massive rocket its first commercial rideshare payload.

While not technically Falcon Heavy’s first rideshare payload and not the rocket’s first commercial rideshare launch contract, Astranis’ first 400 kg (~900 lb) MicroGEO satellite nevertheless appears set to become the first commercial rideshare payload to actually fly on the world’s largest operational rocket. Not all that dissimilar to Starlink in scope and its desire to disrupt a stagnant industry, Astranis wants to offer global communications services providers a different route to geostationary internet and broadcast solutions. Unlike SpaceX’s constellation, the startup’s MicroGEO satellites are designed for geostationary orbits ~36,000 km (~22,200 mi) above Earth’s surface and more than 60 times higher than Starlink.

However, like Starlink satellites, MicroGEO will feature exceptional density (throughput per kilogram), weighing a magnitude less than average modern geostationary communications satellites while still offering up to 10 Gbps of bandwidth. Expected to cost around $40M apiece compared to ~$100M+ for most traditional offerings, the value proposition of small Astranis satellites with 5-10 times less bandwidth admittedly gets a bit blurrier, but the company should still offer a viable alternative for companies and countries that just don’t need a massive satellite.

For example, Astranis’ first customer and the buyer behind the first MicroGEO satellite – known as Aurora 4A – is Pacific Dataport, a company focused on delivering connectivity throughout Alaska – one of the most remote and sparsely populated places on Earth. That combination of attributes makes providing broadband communication services spectacularly difficult and satellite internet the perfect (and, to an extent, the only viable) solution. However, a full $100M+ geostationary communications satellite with 50-100+ Gbps of bandwidth would likely far outweigh the needs of Alaska’s ~730,000 residents – especially when most Alaskans live in the state’s few large cities, most of which already have passable internet connectivity.

As such, it’s easy to see why a small but high-performance geostationary satellite like the kind Astranis offers might be a perfect fit for an Alaskan internet provider. While low Earth orbit (LEO) constellations like OneWeb and SpaceX’s Starlink do offer far more bandwidth and a user experience potentially as good or better than a wired connection almost anywhere on Earth, both companies first have to launch hundreds or thousands of satellites to ensure continuous coverage. Both Starlink and OneWeb are a ways away from offering continuous coverage in polar regions.

Geostationary satellites – especially those as small as Aurora 4A – offer a significant shortcut, requiring just a single satellite and ground stations in one or a few very specific regions to fully complete a communications network. Of course, thanks to universal limits posed by the speed of light, geostationary internet customers end up saddled with extreme latency (ping on the order of 300-1000ms) and strict individual bandwidth limits. But in places like Alaska, where there can easily be no alternative for the most rural residents, Astranis – or just about anything – could bring welcome relief.

Now, Astranis says it has moved the first MicroGEO satellite from a SpaceX Falcon 9 rocket to rideshare payload on Falcon Heavy’s upcoming ViaSat-3 launch, scheduled no earlier than Q2 2022. According to the startup, doing so will allow the tiny satellite to begin operations over Alaska mere days or a few weeks after launch, saving months of orbit-raising thanks to Falcon Heavy’s performance. That’s only possible because, as the Astranis press release also revealed, Falcon Heavy is scheduled to launch the 6.4 ton (~14,100 lb) ViaSat-3 and 400 kg (~900 lb) Aurora 4A satellites directly to geostationary orbit (GEO). If Falcon Heavy’s upcoming USSF-44 mission launches on schedule next month, ViaSat-3 will be SpaceX’s second direct-to-GEO mission ever and the company’s first for a commercial customer.

Assuming SpaceX is still able to recover two – or even all three – of Falcon Heavy’s side boosters while launching almost 7 tons (~15,500 lb) of satellites directly to GEO, it will also demonstrate just how much of a force to be reckoned with it really is, well and truly leaving competitors ULA and Arianespace with nowhere to hide on the open market.

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.
