On the morning of Friday, July 6, Andrew Branagh received a call that would put his company’s 30-year experience in the field to the test. Branagh, who serves as the CEO of Arcata-based Wing Inflatables, had been asked by Elon Musk’s engineering team from SpaceX to construct an inflatable escape pod for the 12 children and their coach who are currently stranded in an air pocket inside the sprawling Tham Luang Nang Non cave complex in Thailand. Knowing that time is of the essence, Branagh and his team got to work.

The stranded members of the Wild Boar Soccer Team have been stranded in the caves since June 23, after a casual excursion into the underground caverns turned into a pitch-black ordeal due to flash floods. The group of 13, comprised of boys aged 11-16 and their 25-year-old coach, were missing until this past Monday, when they were located by two UK divers. The children and their coach have been given food and survival supplies, and on Tuesday, a doctor and a nurse spent the night with them. While the group is safe for now, however, retrieving them is not easy, considering that they are located 2.5 miles away from the entrance to the caves. Parts of the cave systems are also underwater, which would force the children to dive into murky waters during their retrieval.

In a tweet on Friday, Elon Musk posted a brief update on Twitter stating that SpaceX and Boring Co. engineers are headed to Thailand in order to see if they can be helpful to the government’s rescue efforts. That was the same day that Branagh woke up to a text and call from the SpaceX team. Branagh notes that the message was brief, but the request was clear.

“Elon has an idea, or our team does.”

Musk’s initial idea to rescue the trapped children is to use an inflatable tube. Considering Wing’s experience in the field, Branagh and his team went to work refining the idea. The result was a submersible “torpedo,” which could hold a person with an air tank and a breathing apparatus. The torpedo is designed to be towed by its front and back, and be sleek enough to be guided through the cave system’s trickiest sections. Branagh opted to utilize 30% of his company’s workforce for the fast-track effort, reducing his business’ usual output by half. The CEO’s gambit worked, and by 9:30 a.m. on Friday, a prototype was ready. Branagh noted that the first rescue pod, which is 7-feet-long, sealed with velcro, and inflatable with the passenger’s exhaled air, was a finished product. There were no throw-away units or re-dos. There was just not enough time.

By 1:00 p.m., Wing’s rescue pod was tested on the Arcata Community Pool, with a certified dive instructor and two individuals who do not know how to swim. The tests were encouraging, with both test individuals being able to breathe comfortably inside the rescue pod. Branagh had also been speaking with Musk and his engineering staff in a conference call.

“He (Elon) was very direct and clear on supporting getting a solution in place,” Branagh said.

By 5:15 p.m., the first set of Wing Inflatables rescue pods were ready to be transported from Arcata-Eureka airport in Northern CA.

Apart from the inflatable pods that the engineers from SpaceX and The Boring Company transported to Thailand on Friday, Musk and his team at LA are also designing a mini-submarine for the children. In a series of tweets over the weekend, Musk stated that the mini-sub would be small enough to fit through the contours of the cave and its hull will be made of the same material as the oxygen transfer tube of a Falcon rocket, making it extremely durable. The mini-sub would have four handles and hitch points for the front and rear, with two air tanks on both front and rear, allowing up to four tanks to be connected.

Rescue efforts for the stranded children are already underway as of Sunday. For this rescue attempt, the children would have to dive using scuba gear into the waters with two experienced divers. Divers who will be conducting the retrieval of the soccer team are expected to spend 11 hours inside the caves, six hours heading to the children, and five hours going out. It remains unknown for now if the rescuers will be utilizing the rescue pods delivered by the SpaceX and Boring Co. team. Musk’s mini-sub continues testing in LA, just in case it’s needed for the cave rescue efforts.

Tesla’s Roadster appearance at SpaceX has merger watchers talking

Tesla’s next generation Roadster was spotted at SpaceX’s Hawthorne headquarters, two weeks after its unveiling.

Tesla’s next generation Roadster turned up at SpaceX’s headquarters in Hawthorne, California on Wednesday, less than two weeks after the car flew off a ramp at its unveiling in Texas.

Photos shared on X by SpaceX Engineer (@DeannaRiceSPCX) show the new Roadster parked outdoors beside the famed Falcon 9 that stands outside company headquarters at the corner of Crenshaw Boulevard and Jack Northrop Avenue. Rocket B1019 was the first orbital-class booster ever to land after a launch on December 21, 2015 after it sent 11 Orbcomm satellites to orbit and then flew back to Landing Zone 1 at Cape Canaveral, which would be the first landing in what became SpaceX’s reusable rocket program. SpaceX chose not to fly it again. After a test fire in Florida, the booster was shipped to Hawthorne and raised upright as a permanent monument in August 2016, as Teslarati reported at the time. Putting the Roadster, which flies on SpaceX cold gas thrusters, next to the rocket that started SpaceX’s landings is symbolic in itself.

The Thrust and Rocket versions of the Roadster use cold gas thrusters fed by composite overwrapped pressure vessels, the same type of tank SpaceX flies on Falcon 9, and Elon Musk described the car as the work of Tesla and SpaceX engineers working together. Tesla lists 0 to 60 mph in under 0.9 seconds for Thrust and under 0.59 seconds for Rocket, while the base Performance model relies on a fan and ground sealing system for grip, as Teslarati detailed in its breakdown of the three Roadster configurations.

Tesla has kept the car in the spotlight since the October 15 event near Waco. Last week, the company posted a video of the Roadster’s fighter jet inspired cockpit, including a Track Mode screen with a “Thruster · 5,500 PSI” readout, which we covered in our look at the Roadster’s center display. Musk also said owners will be able to ask the car to perform the stunts autonomously, and promised a looping track at Tesla’s Texas headquarters.

The visit comes as special committees at Tesla and SpaceX weigh a possible merger, a step Musk confirmed on SpaceX’s third quarter earnings call. The Roadster, built on SpaceX hardware, has become one of the clearest examples of the two companies already building products together.

Musk said at the unveiling that Roadster production will begin in 2028. Reservations are open with a $50,000 payment, Thrust is listed as a limited release and Rocket is invite only. Tesla says the car is not approved for public road use.

Verizon, AT&T and T-Mobile are trying to shut Starlink out before FCC vote

AT&T, Verizon and T-Mobile want 290 MHz cut from an FCC satellite plan before Thursday.

AT&T, Verizon and T-Mobile are asking the Federal Communications Commission to pull nearly 300 MHz of spectrum out of a proposal that would let satellite companies like SpaceX offer cell service directly to ordinary phones. The request lands one day before the agency votes on it.

The FCC will vote Thursday, October 29, on a notice of proposed rulemaking that would make an additional 482 MHz available for direct to device service, expanding the number of eligible bands from five to 13, according to the FCC fact sheet. It would also scrap the rule requiring a satellite operator to lease spectrum from carriers, replacing it with a certification that the operator has coexistence agreements in place or holds the terrestrial license itself.

That second path matters for SpaceX. As Teslarati reported earlier this month, SpaceX agreed to buy Grain Management’s nationwide 800 MHz portfolio to turn Starlink Mobile into a full US carrier, adding to the spectrum it already bought from EchoStar.

The carriers want two bands removed, 2.5 GHz and 3.45 GHz, which make up 290 MHz of the 482 MHz on the table. Through industry group CTIA, they argued that about 300 million users depend on those bands and that satellite operations in them are not technically feasible. T-Mobile, which calls 2.5 GHz the foundation of its Ultra Capacity 5G network, said in its own filing that satellite interference could wipe out up to 96% of a cell site’s uplink coverage area and cut uplink speeds by 88% to 99%.

Executives from all three carriers met with FCC staff on October 20, and T-Mobile CEO Srini Gopalan met separately with FCC Chairman Brendan Carr. T-Mobile’s role stands out because it is still SpaceX’s US launch partner for Starlink Mobile. The three carriers have also teamed up on their own satellite joint venture to pool spectrum, a move widely seen as a response to Starlink.

SpaceX is asking for the opposite. In an October 23 filing after meetings with FCC staff and commissioners’ offices, the company asked regulators to add the 902 to 928 MHz band to the proposal. “Doing so now saves time later,” SpaceX wrote. The company also asked the FCC to modernize interference rules and align satellite deployment requirements with those for terrestrial cell networks, saying the goal is to let satellite and ground networks work together so Americans stay connected wherever they are.

The carriers have not been shy about how they view SpaceX as a competitor. On Verizon’s third quarter earnings call Monday, its chief executive said Starlink Mobile “just can’t compete with a terrestrial network” and estimated SpaceX would need four to six years and $300 billion to $500 billion to build a full US carrier network.

Thursday’s vote will not settle which bands survive. Adopting the notice opens a public comment period, with final rules to come later in the proceeding. The FCC already considered and rejected 2.5 GHz for satellite coverage once, in 2024. SpaceX also is not the only satellite player watching: the FCC approved Amazon’s $11.6 billion acquisition of Globalstar on October 27, giving its planned direct to device fleet its own mobile satellite spectrum.

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.
