SpaceX has kicked off a series of major upgrades planned for its East Coast fleet of drone ships, centered around Just Read The Instructions (JRTI) and most recently culminating in the apparent fabrication of a second tank-like rocket recovery robot.

Back in Q4 2019, West Coast drone ship JRTI officially departed the Port of Los Angeles berth it operated out of for 3+ years — traversing the Panama Canal, making a weeks-long pit-stop in a Louisiana port, and ultimately arriving at Port Canaveral on December 11th. The modified barge spent more than a month relatively untouched – as was the somewhat mysterious cargo it had brought with it from the Gulf Coast – before SpaceX began JRTI’s long-awaited upgrades around a month ago.

For almost half a year, it’s looked like that SpaceX would move its West Coast drone ship to Florida after the company’s Vandenberg Air Force Base (VAFB) pad entered a major lull in launch activities in early 2019. Aside from one launch in June 2019, SpaceX’s West Coast pad has remained unused and that isn’t expected to change anytime soon. With Cape Canaveral potential reopening its dormant polar launch corridor just weeks from now, it’s entirely possible that SpaceX will be able to perform all of its planned launches from Florida alone for at least the next 6-12 months. Targeting more than 30 East Coast launches in 2020 alone, SpaceX could also benefit from at least one additional drone ship to continue high-volume Falcon booster recoveries without ship availability becoming a major launch constraint. Thankfully, JRTI may be the perfect solution.

Informally known as ‘Octagrabber’, a reference to the robot’s primary function, SpaceX has been using the only operational instance of the vehicle on drone ship Of Course I Still Love You (OCISLY) for more than two years, beginning in 2017. While far from autonomous, Octagrabber helps SpaceX’s maritime rocket recovery team minimize the risks workers are subjected to and gives the company a bit more flexibility to attempt Falcon booster landings in less-than-pristine ocean weather.

While Falcon boosters are relatively stable once landed, thanks to the vast majority of their empty mass being concentrated around their nine Merlin 1D engines, even moderate waves can cause them to slip and slide around the drone ship deck.

In fact, the best operational demonstration of the value of Octagrabber-style recovery robots came after SpaceX’s historic Falcon Heavy triple-booster recovery in April 2019 – the first time all three of the rocket’s first stage boosters successfully landed after liftoff. As it turns out, thanks to moderate hardware differences between Falcon Heavy center core boosters and normal Falcon 9 boosters, OCISLY’s Octagrabber robot did not have the attachment mechanisms needed to ‘grab’ the center core (B1055, in this case). In theory, this could be a non-issue but the drone ship unfortunately ran into high seas, making its deck to pitch and tilt and ultimately causing to B1055 to tip over, breaking in half and effectively destroyed the booster.

With Octagrabber robots, drone ships should almost never lose recovered boosters because of high seas (within reason). As such, it should come as no surprise at all that SpaceX is building a new recovery robot for drone ship JRTI – the newest addition to its Florida fleet.

Aside from the discovery of a second Octagrabber being built at SpaceX’s former East Coast Starship factory, the nature of other upgrades planned for drone ship JRTI are more mysterious. For several months, the rocket landing platform has had almost a dozen massive generators and new thruster pods stored on its deck, seemingly waiting on an unknown impetus for their installation. In recent weeks, visible work to prepare the new hardware for installation has begun.

Notably, the thrusters and power supplies that seem destined for installation on JRTI would make for a dramatic upgrade, potentially giving the drone ship more power than the tug boats that must currently tender and tow them to landing zones. In other words, that’s a complicated way of saying that SpaceX may be trying to make drone ship JRTI almost entirely independent of contracted tugboats, potentially simplifying and lowering the cost of booster recoveries.

One day soon, SpaceX’s upgraded drone ships may be able to recover boosters and return them to shore without any human technicians. (Richard Angle)

While less likely, it’s also possible that SpaceX is finally in a position to fully realize the “autonomous” namesake of its autonomous spaceport drone ships (ASDS), with high-powered thrusters potentially giving JRTI the ability to leave port, cruise to Atlantic Ocean landing zones, deploy an Octagrabber, and return to port with a booster – all without humans in the loop. That capability is likely still on the horizon but powerful thrusters and generators would bring port-to-port drone ship autonomy within SpaceX’s grasp in the near future.

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.
