SpaceX has completed a Falcon 9 static fire test ahead of the company’s first launch of 2019, kicking off what is looking to be a truly jam-packed year for Falcon 9 and BFR. Most important, of course, is SpaceX’s primary business and main sources of revenue – safely and reliably launching customer satellites, payloads, and – soon – astronauts into orbit.

Previously tasked with launching heavy communications satellite Telstar 18V in September 2018, Falcon 9 B1049 is now set to launch an arguably historic mission for both SpaceX and customer Iridium, the eighth and final contracted launch of the upgraded Iridium NEXT satellite communications constellation.

Struck all the way back in June 2010, Iridium’s decision to award the full NEXT constellation launch contract to SpaceX less than two weeks after Falcon 9’s first and only launch may well be the greatest calculated leap of faith in the history of commercial spaceflight. SpaceX did admittedly offer an unbeatable price ($492M for eight launches, $61.5M per launch) that may have allowed Iridium to afford a new constellation in the first place, but the risk Iridium took was truly immense at the time.

Originally launched between 1997 and 1998, the first Iridium constellation became and still remains the only satellite communications constellation in history to offer global and persistent coverage anywhere on Earth, allowing those with Iridium devices to guarantee connectivity no matter where they are. To some extent, the original constellation has become a subtle but omnipresent backbone of a huge variety of ventures, companies, and services, ranging from marine vessel tracking and emergency response to the go-to solution for those heading far off the beaten path. As just one small example, SpaceX’s large fleet of sea-going vessels and its cross-country transport infrastructure both rely on Iridium for streamlined company-wide movement tracking, making life considerably easier for logistics and planning teams.

Iridium’s decision to use SpaceX for its NEXT constellation likely also gave SpaceX a massive stature boost, taking it from the company with just a handful of commercial contracts that had failed three of its last five launches to the company that secured what was at the time the largest single commercial launch contract in history. Alongside NASA’s Commercial Orbital Transport Services (COTS) and Resupply Services (CRS) commitments (~14 launches as of 2010), Iridium NEXT raised SpaceX’s commercial manifest from perhaps 2 missions to ~10 while also taking the value of those contracts from an almost negligible sum to well over half a billion dollars.

Although SpaceX and Iridium originally planned for launches to take place over a roughly 24-month period stretch from 2015 to 2017, unplanned technical delays and a duo of catastrophic Falcon 9 failures (CRS-7 and Amos-6) in 2015 and 2016 ultimately pushed Iridium NEXT’s launch debut back several years. Despite those immense hurdles and a range of smaller issues, SpaceX and Iridium were finally able to begin launching satellites in January 2017 and have continued to consistently do so every 3-4 months since then. Aside from one partial NASA rideshare mission that featured five NEXT satellites in May 2018, all seven launches have placed ten NEXT satellites (weighing approx. 10,000 kg or 22,000 lb total) in a variety of low polar orbits without a single known hitch.

Falcon 9 enters the era of reusability

Closely following SES, NASA, and SSL (BulgariaSat), Iridium also became the fourth commercial entity to launch on a flight-proven Falcon 9 rocket for the launch vehicle’s fourth flight-proven mission ever. Iridium-8 will become the fourth constellation launch to fly aboard a sooty Falcon 9 rocket, meaning that a full 50% of the next-gen satellites will have launched on reused rockets, easily one of the coolest bragging rights ever. Currently standing at 65 NEXT satellites in orbit and rapidly nearing operational status, Falcon 9 B1049 and a fresh upper stage will (fingers crossed) place the last ten satellites in orbit to complete the constellation’s last plane and seal the last gap in its perfect global coverage.

Although NEXT would have been valuable for the sole reason that its predecessor satellites are now 5-10 years past their designed lifespans, NEXT will also serve to dramatically increase Iridium’s overall bandwidth, slash concurrent user bottlenecks, and provide a platform for new services like Aireon, which hopes to become the first operator of a truly commercial aircraft tracking service with global satellite-based coverage.

All things considered, it will be hugely bittersweet to watch Iridium and SpaceX’s direct relationship come to a close with the launch of Iridium-8. Aside from nine additional on-orbit spares once all 75 are launched, Iridium will also have a complement of six more spares that will be kept in storage on the ground until they are required in orbit. If or when those times come, SpaceX will be able to compete with other launch providers for the opportunity to carry maybe one or two Iridium satellites – likely as rideshare payloads – into orbit sometime in the future.

In the meantime, stay tuned for Iridium-8’s official launch time and date, likely to be announced by SpaceX sometime within the next 24-48 hours.

Tesla shows what Roadster drivers will see on screen before thruster activation

Tesla’s Roadster video reveals a fighter jet inspired cockpit with a 5,500 PSI thruster gauge.

Tesla has given future owners their clearest look yet at the cockpit of its next generation Roadster. In a 34 second video posted to X on Friday afternoon, the company walked through the car’s touchscreen with a caption: “Inspired by fighter jet cockpits, Roadster’s interface was designed around the pilot.”

The clip opens on a black screen with red graphics and a 3D wireframe of the car, which sits beside the Roadster’s squared off yoke. Tapping parts of the model brings up controls for the rear wing, including low drag and high downforce positions, along with a charging page with a charge limit bar and a small music player. A row of tabs along the bottom reads Home, Vehicle, Listen, Climate and Navigate.

Most of the video is spent in Track Mode. The dashboard shows a live circuit map, a list of session lap times, brake and motor temperatures, and pressure and temperature readouts for each tire. A setup page lets the driver pick Auto, Low Drag, High Downforce or Custom aero modes, adjust aero balance and brake balance, and switch stability and traction control off. Along the bottom, a status bar reads “Thruster · 5,500 PSI” next to a “Boost Ready” indicator.

That gauge ties the software to the hardware Tesla showed off near Waco, Texas on October 15. The Thrust and Rocket versions use cold gas thrusters fed by carbon overwrapped pressure vessels, and Tesla lists 0 to 60 mph times of under 0.9 seconds and under 0.59 seconds for them, as Teslarati detailed in its breakdown of the three Roadster configurations. The base Performance car relies on a fan and ground sealing system for grip, and the aero settings on screen match the active wings and suction setup covered in our look at how the Roadster generates downforce.

The Roadster layout is a departure from the rest of Tesla’s lineup. Instead of a map centered screen, the Roadster puts the car itself at the center of the home page, and Tesla’s Roadster page lists two smaller forward displays alongside the main touchscreen. Tesla has not said whether any of the Track Mode telemetry will make its way to the Model 3 Performance or other vehicles.

The interface could still change before deliveries. Elon Musk said at the event that Roadster production will begin in 2028, and Tesla says the flagship Rocket version is not approved for public road use. Reservations are open with a $50,000 payment, while Thrust is listed as a limited release and Rocket is invite only.

Those who want to see the car in person will get their first chance this weekend. The Roadster goes on display in the lobby of the Petersen Automotive Museum in Los Angeles from October 24 to 27, according to Sawyer Merritt, the first time the public will be able to view it up close.

Tesla reveals Optimus Academy, where robots teach themselves

Tesla has begun building production quality Optimus robots in Fremont and revealed its training plan.

Tesla has started building Optimus on the high volume line it set up inside its Fremont factory, and the company says the robots coming off it are the first that meet the bar for a real product. “The bots coming off this line are the first production-quality bots that we have manufactured,” Tesla wrote in its third quarter shareholder letter, adding that it has “proven that the current manufacturing process for Optimus is suitable for a commercial product.”

The line sits in space that built the Model S and Model X until this spring. Tesla cleared the old vehicle line in 46 days, as Teslarati reported in July, to make room for robot production sized for one million units a year. On Wednesday’s earnings call, Elon Musk said most of the equipment for that capacity is already in Fremont, with output set to climb toward roughly 20,000 robots a week as the line ramps.

Musk described the ramp as a classic S curve. “The growth of Optimus is an S curve, but the initial curve is a shallow slope,” he said. The team is now refining the robot’s AI, electromechanical design, reliability and service life, and Musk expects that work to be finished by the end of next year, when Tesla plans to start delivering Optimus to outside companies for dangerous, repetitive and around the clock jobs.

The most interesting part of the call was how Tesla plans to teach the robots. Its cars send real driving data back to the AI team from millions of vehicles, but Optimus has no fleet like that yet. “A big difference with Optimus versus the cars is we don’t have this vast fleet of cars from which we can gather training data,” Musk said. Tesla’s answer is an Optimus Academy, where 10,000 to 20,000 robots will practice a wide range of tasks and feed what they learn into the next version of the model. Every unit off the Fremont line becomes a source of that training data.

Smarter hardware is on the way too. Tesla plans to put its AI5 chip into Optimus next year, and Musk said a new Optimus video should arrive within one or two months showing the robot completing tasks driven by AI rather than preprogrammed motions. He took aim at rival humanoid demos that only run scripted routines, saying those would not hold up in the real world.

The supply chain is lining up behind the program. In September, Tesla certified Tuopu, Joyson and Sanhua as mass production partners for Optimus components. A far larger Optimus factory is also rising at Giga Texas, where drone footage from Joe Tegtmeyer showed the steel frame nearing completion, and Musk has pegged that plant’s long term target at 10 million robots a year.

Tesla executives also said Optimus production costs are trending toward the expected manufacturing cost of Cybercab, a sign the robot is being engineered for volume from the start. The hands remain the toughest piece of the design, a point Musk also made at the X Takeover event earlier this month, as Teslarati covered at the time, and that is where much of the current engineering effort is focused.

The Starship moon landing number NASA and Elon Musk can’t agree on

Musk disputes NASA estimate of 22 Starship launches for Moon landing, predicting 6 to 8.

Elon Musk is disputing a new NASA safety panel estimate of how many Starship launches it will take to put astronauts on the Moon, saying the real number will be less than half the panel’s figure.

On Thursday, NASA’s Aerospace Safety Advisory Panel held its quarterly public meeting. Panel member Charlie Precourt, a former NASA astronaut, flagged the fueling process for SpaceX’s lunar lander as a major risk for Artemis IV, the mission planned to land a crew on the Moon in 2028. “We need to keep our eyes on numerous required fuelings for the lander,” Precourt said, according to Ars Technica. “I think the last estimate is around 22 flights.”

Ars Technica’s Eric Berger posted the comment on X, and Musk replied. “That’s way too high,” Musk wrote. “Actual number will be more like 6 to 8.”

The disagreement comes down to a basic problem with sending a ship as large as Starship to the Moon. Starship burns nearly all of its propellant just reaching Earth orbit, so it cannot continue on to the Moon without stopping for a refill. SpaceX’s answer is a gas station in space. First, a Starship that works as a storage tank, called a depot, is launched into orbit. Then a series of tanker Starships launch one at a time, dock with the depot and pump their leftover propellant into it. Once the depot is full, the lunar lander version of Starship launches, docks, fills up and heads for the Moon.

Every tanker trip is its own full rocket launch, which is why the count matters. More launches mean more time, more cost and more chances for something to go wrong before astronauts ever leave Earth. Berger estimated that even if SpaceX reaches twice weekly Starship launches by the end of 2027, filling a depot at the panel’s number would still take roughly three months.

How many tankers are needed depends mostly on how much propellant each one can carry to orbit and how much is lost along the way. Starship’s fuel and oxygen are stored at extremely cold temperatures, and some of it slowly boils off while waiting in orbit. More is lost in each transfer. NASA appears to be working from what Starship can lift today, while Musk’s range assumes a more capable rocket.

Musk has pushed back on higher counts before. In 2021, after a government document suggested 16 launches, he called that “extremely unlikely” and said eight tankers would be the most required.

Much of the answer depends on hardware SpaceX has not finished flying. As Teslarati noted earlier this year, the company plans to carry out the refueling process with its upgraded V3 Starship, and Precourt described Artemis IV as carrying “a large number of firsts.” He also praised NASA Administrator Jared Isaacman’s team for working to clear obstacles for both SpaceX and Blue Origin, whose Blue Moon lander does not rely on orbital refueling for its first mission.
