SpaceX’s spectacular USSF-67 Falcon Heavy launch in photos
On January 15th, SpaceX’s Falcon Heavy rocket lifted off for the second time in 75 days to launch another batch of US military payloads into orbits tens of thousands of kilometers above Earth’s surface.
Six and a half hours later, the US Space Systems Command (SSC) confirmed that Falcon Heavy had again completed the exceptionally difficult launch without issue. To deliver the USSF-67 mission’s payloads directly to geosynchronous orbit (GSO), the giant SpaceX rocket had to sacrifice one of its potentially reusable boosters and complete a complex six-hour ballet of rolls, burns, and spacecraft deployments. And for the second time in a row, Falcon Heavy did so without apparent issue.
In an SSC press release [PDF], Maj. Gen. Stephen Purdy, program executive officer for Assured Access to Space, said that the group “had another fantastic launch today on a Falcon Heavy.” He added that “while the launch itself was impressive,” he was “most proud of the fact that we placed important [national] capabilities into space.” And an impressive launch it certainly was.

A Falcon (Heavy) spectacle
As previously discussed, USSF-67 was Falcon Heavy’s first twilight launch. The extraordinary cadence of SpaceX’s workhorse Falcon 9 rocket, which Falcon Heavy is derived from, caused twilight launches and the incredible light shows they can produce to become a fairly routine phenomena. But just under five years after its February 2018 debut, there had still never been a Falcon Heavy launch ‘jellyfish’ or ‘nebula.’ That thankfully changed on Sunday.
The rocket lifted off just ten or so minutes after sunset and soared into the fading purple skies. Those skies were still relatively bright at ground-level, reducing the amount of contrast, but the resulting light show was still spectacular as Falcon Heavy and its immense exhaust plume ascended back into the sunlight. The artificial sunrise lit up that pillar-like plume with the colors of sunrise and, eventually, bright daylight.
Close-up views enabled by tracking telescopes captured the true drama, which began shortly after Falcon Heavy’s twin side boosters separated from the rocket’s main core stage and upper stage, flipped around, and ignited their engines to fly back to the Florida coast they’d only just lifted off from. As the nine-engine center core continued towards space, each booster fired up one and then three Merlin 1D engines for their boostback burns.
A view from Astronomy Live captured the moment of boostback burn ignition, during which the side boosters visibly blasted ‘craters’ the Falcon Heavy center core’s much more powerful plume. As those plumes interacted, the fluid dynamics and light produced by multiple Merlin 1D engines combined to create chaotic whisps of orange, red, and yellow – akin to an exploding nebula. The moments prior were also spectacular as the two side boosters, lit up by direct sunlight against the nearly black sky, began gently floating away from the center core and spinning around with bursts from several nitrogen gas thrusters – a brief moment of serenity before the violence of engine ignition.
On a chariot of fire
But as Maj. Gen. Purdy noted, the purpose of USSF-67 – spectacle aside – was to carry a number of important payloads into orbit.
“After both side boosters touched down, SpaceX ended its live coverage at the request of the Space Force, reiterating the mission’s secretive customer and nature. The USSF hasn’t confirmed much about the USSF-67 mission’s payloads, but Falcon Heavy is known to be carrying a geostationary communications relay satellite called CBAS-2 and likely built by Boeing. CBAS-2 is joined by Northrop Grumman’s third Long Duration Propulsive EELV or LDPE-3A, a combination of a propulsive kick stage and a satellite. LDPE-3A is carrying a collection of rideshare satellites and payloads and is designed to operate for months in orbit. Using USSF-44 as a guide, the total USSF-67 payload could weigh roughly 3.75 to 4.75 tons (8,250-10,500 lb).”
Teslarati.com – January 15th, 2023
The same SSC press release provides more detail, noting that LDPE-3A carries two hosted payloads – Catcher and WASSAT. Catcher is a space weather instrument developed by the Aerospace Corporation, while WASSAT is a prototype [PDF] of a wide-angle observation instrument designed to track other satellites in GSO. LDPE is also hosting “three payloads developed by the Space Rapid Capabilities Office (SRCO),” including “two operational prototypes for enhanced situational awareness, and an operational prototype crypto/interface encryption payload providing secure space-to-ground communications capability.”
Two down, one to go
For Falcon Heavy side boosters B1064 and B1065, both of which supported USSF-44 and USSF-67, their missions are far from over. Their second successful side-by-side landing has cleared the boosters to be reused on a third US military launch called USSF-52. Originally known as AFSPC-52, the mission was Falcon Heavy’s first operational US military launch contract and the first time the rocket beat competitor United Launch Alliance (ULA) during a competitive procurement.
Next Spaceflight reports that USSF-52 is scheduled to launch no earlier than April 10th, 2023, less than three months from now. Once that mission is complete, Falcon Heavy will have no more US military missions on contract, although more will almost certainly be rewarded sooner than later. USSF-52 is sandwiched between two other Falcon Heavy launches. Next Spaceflight also reports that Falcon Heavy could launch the ViaSat-3 communications satellite as early as March 2023 and the Jupiter-3 (EchoStar 24) communications satellite as early as May 2023, making for a busy 90 days.
For that trio to happen as scheduled, SpaceX will have to beat Falcon Heavy’s record 75-day turnaround, which has coincidentally (?) occurred twice: first between Arabsat 6A and STP-2, and again between USSF-44 and USSF-67. Including USSF-67, SpaceX has up to five Falcon Heavy launches scheduled this year.

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.
