SpaceX assembles Falcon Heavy rocket for first launch in 40 months

Published

SpaceX has assembled the fourth Falcon Heavy for the rocket’s first launch in 40 months.

A photo shared by SpaceX on October 23rd shows that it has mated Falcon Heavy’s three first stage boosters together while preparing for prelaunch testing. Simultaneously, workers have completed the equally important task of converting 39A’s transporter/erector (T/E), which has been configured for single-core Falcon 9 rockets for over three years.

The transporter/erectors SpaceX use for all Falcon launches are a bit like a mobile backbone and launch tower combined. Their first purpose is to transport horizontal Falcon rockets to and from their integration hangars and launch pads. They’re also tasked with raising Falcon rockets vertical and lowering them back down for transport or worker access. Most importantly, they connect to a pad’s ground systems and distribute propellant, gases, power, and communications to Falcon 9 and Falcon Heavy through multiple umbilicals and quick-disconnect ports.

Falcon Heavy, which can only be launched out of LC-39A, has three times as many boosters as Falcon 9 and necessitates significant modifications to the pad’s T/E when switching between the two. The process is much harder when moving from F9 to FH, and waiting almost three and a half years between Falcon Heavy launches likely hasn’t made the conversion any easier. But on October 23rd, after numerous tests and weeks of work, the Pad 39A T/E picked up the ‘reaction frame’ that attaches to the bottom of Falcon rockets and was brought horizontal.

Thanks to the nature of Falcon Heavy and Pad 39A’s infrastructure, what happens next is more or less guaranteed. During normal Falcon 9 operations, 39A’s integration hangar is large enough for two or three unrelated Falcon boosters to remain while the T/E rolls inside to pick up a full Falcon 9. More importantly, Falcon 9’s booster and upper stage can technically be integrated off to the side and craned onto the T/E when ready. But with Falcon Heavy, which has a first stage akin to three Falcon 9 boosters sitting side by side, there isn’t enough room inside the hangar to integrate the rocket with the T/E inside.

For Falcon Heavy, the T/E can thus only roll back into the hangar once the rocket’s three boosters and upper stage have been fully assembled and are suspended in mid-air. SpaceX’s October 23rd photo shows that three of the four cranes required for that lift appear to already be in position, further confirming that T/E rollback is imminent. Once the T/E rolls back to the hangar and Falcon Heavy is attached, the rocket will eventually be transported to the pad and brought vertical for wet dress rehearsal (WDR) and static fire testing.

Update: SpaceX began rolling the T/E to Pad 39A’s integration hangar around 1 am EDT, October 24th.

The US Space Force’s USSF-44 payload – a mysterious pair of satellites that are more than two years behind schedule – will almost certainly not be installed on Falcon Heavy during prelaunch testing, so the rocket will need to roll back to the hangar at least one more time after testing to have its payload fairing attached.

Combined, that prelaunch process could easily take a week or more. Multiple sources report that Falcon Heavy is scheduled to launch no earlier than (NET) 9:44 am EDT (13:44 UTC) on Halloween, October 31st. But even if the rocket rolls out today (Oct 24), the odds are stacked against Falcon Heavy sailing through its first integrated prelaunch tests in 40 months, and delays are likely.

For Falcon Heavy’s fourth launch, all three of the rocket’s boosters – B1064, B1065, and B1066 – are new, as are its upper stage and payload fairing. An FCC permit for the launch has confirmed that SpaceX will intentionally expend the rocket’s new center core while its twin side boosters will attempt a near-simultaneous landing back at Cape Canaveral. USSF-44 will be SpaceX’s first attempted launch directly to geostationary orbit (GEO), an exceptionally challenging mission that requires the rocket’s upper stage to coast in space for around 4-6 hours between two major burns.

If successful, Falcon Heavy will insert the USSF-44’s mystery satellites into a circular orbit ~35,600 kilometers (~22,150 mi) above Earth’s surface. At that altitude, orbital velocity matches Earth’s rotation and spacecraft can effectively hover – indefinitely – above their region of choice.

Falcon Heavy is the most powerful operational rocket in the world. At liftoff, it weighs around 1420 tons (~3.1M lb) and can produce more than 2300 tons (~5.1M lbf) of thrust. In a fully expendable configuration, Falcon Heavy can launch 26.7 tons (59,000 lb) to an elliptical geostationary transfer orbit and 63.8 tons (141,000 lb) to low Earth orbit. SpaceX doesn’t advertise its direct-to-GEO capabilities.

Tesla starts Full Self-Driving rollout to owners in Australia

“To have this car drive me around Brisbane for an hour, we’re talking in the city, motorway, spaghetti bowl of on-ramps, it handled it so well. It was mind-blowing.”

Tesla has already started rolling out its Full Self-Driving suite to owners in Australia after officially launching the driver assistance suite in the country yesterday.

Earlier this week, Tesla seemed to be moving toward the launch of Full Self-Driving (Supervised) in Australia after numerous media members received early access to test its performance.

Tesla officially launched Full Self-Driving (Supervised) in Australia yesterday. The company told media members who got early access to the suite that the rollout would begin with Hardware 4-equipped Model 3 and Model Y vehicles.

The release would be slow and gradual, with the process performed in stages.

The first stage of the rollout has already begun in Australia:

Tesla is reminding drivers in Australia who are using the suite for the first time that they must not become complacent while FSD is in operation. It is not fully autonomous and still requires the driver to remain attentive to road conditions and the vehicle’s surroundings.

Currently, the suite is only available to purchase outright, and it comes at a cost of $10,100. A subscription model is in the works, similar to the one in the United States, but Tesla has not yet announced its plans or pricing model for this.

Australia is the sixth country to receive Full Self-Driving (Supervised), or at least some version of it, as the United States, Canada, Mexico, China, and Puerto Rico all have access to the suite currently. In China, it is slightly different and is referred to as “City Autopilot” due to regulatory boundaries.

Early reviews of the suite have been very strong, as local media have also had the opportunity to try it, with one journalist saying, To have this car drive me around Brisbane for an hour, we’re talking in the city, motorway, spaghetti bowl of on-ramps, it handled it so well. It was mind-blowing.”

Tesla expands crazy new lease deal for insane savings on used inventory

Tesla was able to work through the hurdles in three states, expanding the deal to New York, New Jersey, and Florida.

Tesla has expanded its new lease deal, offering people insane savings on used inventory.

Last week, we reported on Tesla offering crazy good lease deals on some of its used inventory, as people were able to grab monthly payments for as little as $225 per month with no money down.

There was only one catch: the deal was only available in California and Texas.

Tesla offers new deal on used inventory that you won’t want to pass up

However, Tesla has been working hard to get the lease deal expanded, and it finally has. Last night, Tesla’s VP of Finance, Sendil Palani, confirmed the deal had made it to three additional states.

Palani explained that the deal was only available in California and Texas because the leasing process requires working through regulatory hurdles in each state. He said it “involves a nontrivial amount of work,” which makes things more difficult to iron out.

Tesla was able to work through the hurdles in three states, expanding the deal to New York, New Jersey, and Florida. It is currently active in those states, Palani said:

Tesla is really making a concerted effort to push its inventory out the door, and many areas already are running low on both new and pre-owned inventory. It has cut prices on some new inventory, while offering these new lease deals on used vehicles that remain.

It is beneficial to the consumer for obvious reasons: cheaper payments and the ability to get a great deal on a car for no money down. Tesla is also getting rid of vehicles that were once thought to be intended for the Robotaxi fleet, but it appears these older hardware vehicles are no longer in the company’s plans for that purpose.

This is the first time Tesla has offered lease deals on used inventory, as it has only offered an outright purchase option in the past. In an effort to boost deliveries and rid itself of older cars, these lease deals are truly beneficial for both parties. It is only a wonder how long they will last.

Elon Musk shares unbelievable Starship Flight 10 landing feat

Flight 10’s Starship upper stage demonstrated impressive accuracy when it came to its target landing zone.

SpaceX CEO Elon Musk recently shared an insane feat accomplished by Starship’s upper stage during its tenth test flight.

Despite the challenges it faced during its return trip to Earth, Flight 10’s Starship upper stage demonstrated impressive accuracy when it came to its target landing zone.

Against the odds

Musk’s update was shared on social media platform X. In a conversation about Starship upper stage’s return to Earth, Musk revealed that the upper stage splashed down just 3 meters (under 10 feet) from its intended target. Considering the size of the Starship upper stage and the ocean itself, achieving this accuracy was nothing short of insane.

Starship Flight 10 was a success as both the Super Heavy booster and Ship upper stage completed all their mission objectives. However, videos and images released by SpaceX showed the upper stage’s heat shield scorched golden-brown and parts of its aft skirt visibly missing. The flaps and other surfaces also bore signs of heavy stress from reentry.

SpaceX highlighted this in a post on X: “Starship made it through reentry with intentionally missing tiles, completed maneuvers to intentionally stress its flaps, had visible damage to its aft skirt and flaps, and still executed a flip and landing burn that placed it approximately 3 meters from its targeted splashdown point,” SpaceX noted.

A key milestone

The result stands in stark contrast to Starship’s earlier test flights this year, when all three prior upper-stage flights in 2025 ended in premature breakup before splashdown. Flight 10 not only marked the first successful splashdown of the year for the Starship upper stage, but it also delivered near-perfect precision despite its battered state, according to a Space.com report.

For SpaceX, this success is a critical proof point in developing a fully reusable launch system. A spacecraft capable of surviving severe reentry conditions and still landing within meters of its target underscores the robustness needed for future missions, including orbital payload deliveries and, eventually, landings on the Moon and Mars.
