SpaceX launch technicians and engineers have officially completed the integration and static fire testing of the second Falcon Heavy rocket ever, nearing the end of preflight preparations for the vehicle’s critical commercial launch debut.
Carrying the commercial communications satellite Arabsat 6A, the rocket will be tasked with placing the massive spacecraft into a high-energy geostationary orbit. After a combination of hurdles and conflicting priorities conspired to delay Arabsat 6A’s launch from mid-2018 to February, March, and eventually, April of 2019, both the spacecraft and rocket are nearly ready to go. If all goes as planned, SpaceX will also complete the first successful launch and near-simultaneous landings of three independent rocket boosters, preparing two of the three boosters for reuse on a launch that could happen as early as June 2019.

Falcon 9 Block 5, meet Falcon Heavy
- With this Falcon Heavy, SpaceX has effectively built – once again – a center stage that is nearly its own rocket, much like the tortured development of the first vehicle’s center stage can be blamed for a lot of its years of delays.
- Based on Falcon 9 V1.2’s Block 3 iteration, Falcon Heavy Flight 1’s center core was effectively outdated a year before it launched, and Falcon 9 Block 5 debuted just three months after its first and last launch.
- Combined with the center core’s untimely demise when it crashed into the Atlantic after running out of engine starter, the now 14 months separating Flight 1 and Flight 2 of Falcon Heavy can be explained by the rocket’s delayed path to the launch site.
- By the time the first Falcon Heavy’s main components were all present in at the launch site, SpaceX was already building Block 5 rockets and was as few as three months away from completely transitioning its Hawthorne, CA factory to Block 5.
- Due to the extensive changes in production incorporated into Block 5, this was effectively a no-turning-back deal where the cost of transitioning back was simply a non-starter.
- By the time Falcon Heavy had launched, and its center core had smashed itself to pieces on the Atlantic Ocean surface, it was far too late to begin producing a replacement copy. One step further, the process of ramping up Block 5 production had been slowed significantly by the drastic changes made across the board, taking SpaceX to the edge of production-related launch delays over the course of 2018.
- Put simply, building two side boosters and a relatively boutique Falcon Heavy center core – all three of which would be inextricably tied together for the foreseeable future – was not a practical option when three separate Falcon 9 Block 5 boosters could instead support 6-12+ launches over a period of six or so months.

(Hopefully) the first of many
- In the nominal event that SpaceX’s second Falcon Heavy launch is an unqualified success, it’s entirely possible that the doors to new markets could be opened as the world and its many spacefaring customers begin to contemplate the existence of an affordable super-heavy-lift launch vehicle – the first of its kind.
- On the outside, Falcon Heavy can begin to look like a bit of a boondoggle from a business perspective. It will have probably cost no less than $750M-$1B to develop, including the Block 5 modifications needed, and likely brought in less than $100M in gross revenue. It’s a black hole that SpaceX currently dumps huge volumes of cash into, in other words.
- However, this sort of observation is far too pessimistic and gives SpaceX far too little credit after some additional careful analysis. As of today, SpaceX has six public launch contracts for FH, two of which are from the USAF/NRO and likely valued around $130M-$150M.
- Purely commercial contracts for Falcon Heavy will probably be closer to $90M-100M, more than competitive with rockets like Atlas 5, Delta IV Heavy, Ariane 5, and other future vehicles like ULA’s Vulcan.
- Within ~12 months, the USAF will likely have awarded 10-16 additional launch contracts to some combo of Falcon 9 and Falcon Heavy as part of the latest EELV (now NSSL) acquisition phase. Assuming SpaceX is one of the two providers chosen, Falcon Heavy could receive numerous additional contracts for heavy military satellites.
- Additionally, NASA is now seriously considering Falcon Heavy for the launch of flagship missions like Europa Clipper and (maybe, maybe not) even Orion missions to the Moon.
- Falcon Heavy could also be the only vehicle in the world with the performance needed for a number of other missions that could arise from the Lunar Gateway, including launching actual segments of the space station and launching deep space cargo missions resupply said Gateway.
- Only ULA’s Delta IV Heavy can marginally compete with Falcon Heavy’s performance, but it typically costs no less than $300M per launch, a 2-3X surcharge over SpaceX’s offering. Due to the utter and complete lack of competition from both a price and performance perspective, SpaceX could essentially have the heavy life market cornered for something like 48-60+ months.
- Offering a unique product with potentially high demand and no real alternative, SpaceX would not be out of place to raise its profit margins significantly, helping to rapidly pay back the capital investment it put into Falcon Heavy’s extended development.
- Regardless, the future of Falcon Heavy has every right to be even more thrilling and diverse than the already impressive Falcon 9.

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.
