Thanks to a temporary reopening of the US federal government, SpaceX was finally able to continue the process of filing FCC and FAA paperwork needed to acquire permits for upcoming launches, including Falcon Heavy.

One such filing related to the first operational Falcon Heavy launch has revealed a fairly impressive statistic: comprised of three first stage boosters, SpaceX indicated that Falcon Heavy’s center core will attempt to land on drone ship Of Course I Still Love You (OCISLY) nearly 1000 km (600 mi) away from its launch site, easily smashing the record for the greatest distance traveled by a Falcon booster in flight.

The same FCC filings also revealed a No Earlier Than (NET) launch date: March 7, 2019. Originally targeted for mid to late February, the complexity and logistical challenges of building, shipping, testing, and delivering two side boosters, a center core, one upper stage, and a payload fairing from SpaceX’s California factory to its Texas test facilities and Florida launch pad unsurprisingly took a small toll on the launch’s aspirational schedule. Nevertheless, if the launch data actually holds to March 7th, SpaceX will not have missed the mark by much considering that this Falcon Heavy – based on new and more powerful Block 5 boosters – is likely a significant departure from the Block 2/Block 3 hardware that has flight heritage from the triple-booster rocket’s Feb. 2018 launch debut.

Just shy of a year after Falcon Heavy’s launch debut, it appears that the rocket’s second and third launches were pushed back by a fundamental lack of production capacity. In other words, SpaceX’s Hawthorne rocket factory simply had to focus on more critical priorities in the 6-9 months that followed the demo mission. At nearly the same time as Falcon Heavy was lifting off for the first time, SpaceX’s world-class production crew was in the midst of manufacturing the first upgraded Falcon 9 Block 5 booster (B1046) and wrapped up final checkouts just 10 days after Heavy’s Feb. 6 launch debut, sending the pathfinder rocket to McGregor, Texas for the first static fire of a Block 5 booster.

In the meantime, SpaceX’s decision to intentionally expend otherwise recoverable reused Falcon boosters after their second launches meant that the company’s fleet of flightworthy rockets was rapidly approaching zero, a move CEO Elon Musk specifically indicated was meant to make room for Block 5, the future (and final form) of the Falcon family. SpaceX’s busy 2018 launch manifest and multiple critical missions for the US government were thus balanced on the success, reliability, and rapid production of a serious number of Merlin engines, boosters, and upper stages. This included B1051 – the first explicitly crew-rated Falcon 9 – and B1054, the first SpaceX rocket rated to launch high-value US military (specifically Air Force) satellites. However, SpaceX also needed to produce a cadre of Falcon 9 boosters capable of easy reuse to support the dozen or so other commercial launches on the manifest.

That gamble ultimately paid off, with Block 5 performing admirably and supporting a reasonable – if not record-breaking – rate of reuse. SpaceX successfully launched B1054 for the USAF, completed B1051 (now at Pad 39A awaiting NASA’s go-ahead), and built enough reusable Block 5 boosters to support nine additional commercial missions in 2018. In hindsight, barring an assumption of a truly miraculous and unprecedented Falcon booster production rate, Falcon Heavy’s next launches were almost guaranteed to occur no fewer than 6-12 months after the rocket’s launch debut – SpaceX’s entire launch business depended on building 5+ unrelated Falcon 9 boosters, while Falcon Heavy customers Arabsat and the USAF were unlikely to be swayed to launch on flight-proven hardware so early into Block 5’s career.

All cylinders firing

Once Falcon 9 B1054 departed SpaceX’s Hawthorne factory (see above) in early October, it appears that the company’s production team pivoted directly to integrating and shipping the next three (or more) Falcon Heavy boosters back to back for the rocket’s second and third launches. The first new side booster departed the factory in mid-November, followed by a second side booster in early December and a (presumed but highly likely) center core at the turn of 2019. Both side boosters have been static-fired in Texas and are now at SpaceX’s Florida facilities, while the center core either just completed its Texas static fire testing or is already on its way East.

 

Once the center core and upper stage make their way to SpaceX’s Kennedy Space Center Pad 39A, the company’s technicians and engineers will be able to integrate the second Falcon Heavy to have ever existed in preparation for a critical static fire test. That could occur as early as February, although the launch debut of Crew Dragon (DM-1) – now NET March from Pad 39A after a relentless string of slips – will likely take precedence over Falcon Heavy and could thus directly interfere with its launch, as the launch pad and transporter/erector (T/E) has to undergo at least a few days of modifications to switch between Falcon 9 and Heavy.

Regardless, the next two Falcon Heavy launches will be well worth the wait. SpaceX’s FCC filings indicate that the center core may travel nearly 1000 km (600 mi) East of Pad 39A to land on drone ship OCISLY after launch, smashing the previous record attempt – during the June 2016 launch of Eutelsat 117WB – of ~700 km (430 mi). That Falcon 9 booster – albeit a less-powerful Block 2 variant – was unsuccessful in its landing attempt, running out of oxidizer seconds before landing. Falcon Heavy’s debut center core also happened to suffer a wholly different but no less fatal anomaly during landing, causing it to miss the drone ship and slam into the Atlantic Ocean at almost half the speed of sound (300 mph/480 km/h).

Known for their rocket performance estimates, NASASpaceflight forum user “Orbiter” first pointed out the impressive distance – gathered by mapping coordinates included in SpaceX’s Jan. 28th FCC filing – and estimated that the Falcon Heavy center booster flying a trajectory as implied could be traveling as fast as ~3.5 km/s (2.2 mi/s) at main engine cut-off (MECO), the point at which the booster separates from the upper stage and fairing. This would be a nearly unprecedented velocity for any Falcon booster, let alone a booster with plans to land after launch. Falcon 9 MECO typically occurs at velocities between 1.5 and 2.5 km/s for recoverable missions, while even the recent expendable GPS III launch saw F9 S1’s engines cut off around 2.7 km/s.

Whether that MECO velocity estimate is correct, Falcon Heavy’s NET March launch of the ~6000 kg (13,300 lb) Arabsat 6A satellite is likely to be an exceptionally hot reentry and recovery for the center core, while the rocket’s duo of side boosters will attempt a repeat of the debut mission’s spectacular double-landing at LZ-1.

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.
