SpaceX assembles Falcon Heavy rocket for first launch in 40 months

Published

on

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.

Elon Musk secretly acquires $1B energy company to power the AI future

Elon Musk flew under the radar with his recent purchase of a $1 billion energy company, according to Federal Trade Commission (FTC) documents.

Transaction number 202612350 listed Tesla and SpaceX frontman Elon Musk as the acquiring party and CF APR Super Holdings LLC as the seller, with New APR Energy, LLC as the acquired entity. The deal, which closed without public announcement, came to light on May 14.

Analysts inferred the deal’s scale from minority stakeholder disclosures, including one report of a 5 percent interest sold for approximately $50.4 million. Fortress Investment Group had purchased APR’s assets in late 2024, rebranded the operation as New APR Energy, and subsequently transferred ownership to Musk.

APR Energy specializes in rapidly deployable power infrastructure. The company maintains one of the world’s largest fleets of mobile gas and diesel turbines, with more than 1.1 gigawatts of generation capacity. Its modular units, which are often trailer-mounted, enable turnkey installations ranging from 20 MW to over 500 MW.

Elon Musk admits he was ‘clearly wrong’ about Anthropic

APR provides full engineering, procurement, construction, operation, and maintenance services for behind-the-meter power plants, serving everything from data centers, utilities, and industrial clients.

The firm has expanded aggressively to meet surging demand, recently adding turbines and deploying over 100 MW for a major AI hyperscaler. Its solutions bridge critical gaps where grid interconnections face delays of two to five years, according to Yahoo.

The acquisition means something more for Musk. As he continues to expand projects in artificial intelligence, especially xAI, his AI venture, there is a greater need to supply energy-intensive supercomputing clusters, including the Colossus project, with what they need: reliable and high-capacity power.

Ownership of APR provides immediate access to flexible generation assets that can be deployed adjacent to data centers, reducing dependence on a strained infrastructure. It also complements Tesla’s energy storage business, so Musk will be able to pull from his own entities to address the rapid scaling demands of AI training and compute.

Tesla has to fix a big problem with its old headlights, NHTSA says

Tesla had a petition protesting a recall to fix a potential issue with 2017-2023 Model Y and Model 3 vehicles’ headlights was denied, as the National Highway Traffic Safety Administration (NHTSA) disagreed with the company’s opinion of things.

The recall covers approximately 19,917 Model Y and Model 3 vehicles built from 2017 to 2023. Tesla initially submitted a noncompliance report for the headlights on these vehicles on March 15, 2024. Tesla then petitioned for an exemption from the fix, which violated FMVSS No. 108 (40 CFR 571.108), arguing that the “noncompliance is inconsequential as it relates to motor vehicle safety.

The NHTSA disagreed, stating that Tesla’s conclusion that the headlights do not increase any risk was not an opinion it shared. The agency said it disagreed with Tesla’s assumption that glare is not increased to surrounding traffic. This issue could be highlighted even more in certain weather conditions.

Tesla will be required to remedy the issue, the NHTSA ruled:

“In consideration of the foregoing, NHTSA has decided that Tesla has not met its burden of persuasion that the subject FMVSS No. 108 noncompliance is inconsequential to motor vehicle safety. Accordingly, Tesla’s petition is hereby denied, and Tesla is consequently obligated to provide notification of and free remedy for that noncompliance under 49 U.S.C. 30118 and 30120.”

The issue here appears to be the angle of the headlights and the brightness they emit during operation. The NHTSA report states that:

“Tesla’s headlamp supplier, Marelli Automotive Lighting, tested 25 right-hand and 25 left-hand lamps, and for this sample, found the maximum photometric intensity measured in the 10°U to 90°U and 90°L to 90°R zone was between 136.2 cd and 230.1 cd for the right-hand lamps and between 117.5 cd and 160.3 cd for the left-hand lamps. According to Tesla, these tests revealed that the photometric intensity of the right-hand and left-hand headlamp lower beam on the subject vehicles may measure as much as 230.1 cd in the 10°U to 90°U and 90°L to 90°R zone, exceeding the maximum photometric intensity by 105.1 cd. Additionally, Tesla states that a left-hand lamp tested by a Transport Canada recognized laboratory measured a maximum of 171.27 cd in the 10°U to 90°U and 90°L to 90°R zone. Despite these measurements exceeding the allowed photometric maximum of 125 cd, Tesla believes that the subject noncompliance is inconsequential to motor vehicle safety.”

Tesla also argued at some points that the headlights had not been deemed responsible for any complaints, accidents, or injuries related to the noncompliance.

NTSB findings on fatal Tesla crash tell a very different story

The NTSB confirmed the driver, not Tesla’s FSD, caused the fatal Texas house crash.

Published

The National Transportation Safety Board released preliminary findings Wednesday confirming that a Tesla driver, not the vehicle’s software, caused a fatal crash in Katy, Texas in June. The driver, 44-year-old Michael Butler, had engaged Full Self-Driving Supervised mode on Rose Hollow Lane, a residential street with a 30 mph speed limit, before manually overriding the system by pressing the accelerator pedal all the way to 100%. Data recovered from the 2025 Tesla Model 3 showed the vehicle was traveling over 70 miles per hour when it struck a home and killed 76-year-old Martha Avila, who was inside. Weather was clear, the road was dry, and it was daylight.

Texas man charged in fatal Tesla crash where he blamed Autopilot

Butler told authorities he had passed out at the wheel. But security camera footage obtained by the NTSB told a different story, and showed the car accelerating through an intersection before leaving the road entirely. Police also found that Butler’s phone had Google searches including the terms “Tesla FSD not aggressive enough 2026” and “Tesla FSD too timid,” raising serious questions about how he was using the system before the crash. Butler has since been charged with manslaughter. The victim’s family has filed a lawsuit against both Butler and Tesla, alleging negligence.

The NTSB findings aligned directly with what Tesla VP of AI Software Ashok Elluswamy had already stated publicly on X in the weeks after the crash, writing that “the driver manually overrode self-driving by pressing the accelerator all the way to 100%.” The data confirmed his account.
