After traveling more than 3500 miles (5600 km), SpaceX autonomous spaceport drone ship (ASDS) Just Read The Instructions (JRTI) began its eastbound transit of the Panama Canal on August 18th, placing the vessel roughly two-thirds of the way to its unknown destination.

As previously discussed on Teslarati, JRTI’s move came as a bit of a surprise and it’s still anyone’s bet if the SpaceX recovery vessel heads for Texas or Florida immediately after exiting the Panama Canal. Nevertheless, JRTI’s presence at either (or, more likely, both) possible destinations arguably centers around the imminent demands of a planned ramp of SpaceX’s Starlink satellite constellation launch cadence, as well as an equally imminent need for recovery assets to support the first suborbital Starship test flights.

On July 31st, JRTI departed Port of Los Angeles – its home for the last four years – under tow behind tugboat Alice C. The duo arrived at the Canal on August 15th and, after a several-day wait in a large passage queue, the drone ship and its paired tugboat are finally on their way through the canal, although traffic still remains high and another day (or several) of waiting is likely in order.

After successfully making it through the first half of the transit, JRTI and Alice C are currently waiting in line while westbound traffic is routed through. That wait will likely last hours, not days, (hopefully) allowing JRTI to exit the canal on Tuesday or Wednesday, leaving drone ship free to head towards its final destination.

JRTI has two possible destinations: Port of Brownsville, Texas or Port Canaveral, Florida. Both options are roughly 1800 mi (3000 km) from the Panama Canal’s western mouth and, extrapolating from the first major leg of the journey, should take Alice C around 8 days to tow JRTI across the finish line. Barring mishaps, the drone ship should thus be able to arrive at its new home sometime in the final week of August – roughly August 27th to the 31st.

To the East, to the Gulf

As previously discussed on Teslarati, there are good cases to make for both potential drone ship destinations. On the East Coast, SpaceX’s plans to ramp up its internal Starlink launch cadence could require multiple drone ship to prevent those ambitions from seriously impacting the company’s commercial launch manifest. The readiness of one or two of the payloads is uncertain, but SpaceX has anywhere from seven to nine Falcon 9 launches scheduled in Q4 2019, requiring a cadence significantly higher than SpaceX’s activity in the first half of 2019.

At the same time, extrapolating from SpaceX’s H1 2019 cadence (1.33 launches per month), more than doubling that average cadence to 3 launches per month in the final quarter seems ambitious, at a minimum. SpaceX has achieved six-launch quarters several times in the last few years, likely a reasonable expectation for Q4 2019. In short, this is all to say that SpaceX has made do with one drone ship in the past while hitting similar launch cadences, meaning that the need for JRTI at Port Canaveral is probably not urgent.

On the Gulf Coast, SpaceX has established a Starship development facility in Boca Chica, Texas, just a handful of miles north of the southernmost tip of Texas. A full-scale, low-fidelity prototype known as Starhopper completed its first test flight on July 25th and is likely just days away from a second test flight. Meanwhile, SpaceX Boca Chica is simultaneously assembling what CEO Elon Musk has described as the “Mk1” orbital Starship prototype and is making spectacularly rapid progress.

Musk recently tweeted that SpaceX’s Mk1 Starship and a second parallel build – Starship Mk2 – could be ready for their first (suborbital) flights as early as late-September or October, followed by one of the spacecraft’s first orbital launch attempt an incredibly ambitious “2-3 months after” the first test flight. Per additional statements from Musk in 2018 and 2019, SpaceX plans to subject either or both of its Mk1 and Mk1 Starships to a high-altitude, high-velocity test program before proceeding to orbital launch attempts.

Said extreme testing could easily involve Starship traveling on high suborbital trajectories dozens or even hundreds of miles above Earth’s surface, potentially demanding an ocean-going landing platform far downrange. Given that Starship is in its very early stages of integrated development, any downrange assets (i.e. JRTI) needed for test flights will need to be very flexible, as Starship launch attempts could easily slip days or weeks with little to no notice.

Best of both worlds

Although pitting options against each other is entertaining and has its uses, the fact remains that once drone ship JRTI has passed through the Panama Canal, traveling from, say, Florida to Texas or vice versa is far less arduous a journey than the trip from Port of LA. In other words, moving JRTI between Port of Brownsville and Port Canaveral every few months should be very little trouble, easily allowing the drone ship to service both Gulf and East Coast recovery needs.

Given that SpaceX’s next Falcon 9 launch is believed to be no earlier than late-October, it’s not even out of the question that JRTI will stop in Brownsville for one month or several before heading to Port Canaveral as SpaceX attempts to complete a very busy Q4 2019 launch manifest. Stay tuned…

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.
